+# 2.70.0
+
+Changes:
+* LocalIP flags on Windows now describe the interface itself — its operational status, its media connection state and its type, for example `ETHERNET_CSMACD`, `IEEE80211` or `SOFTWARE_LOOPBACK` — instead of the `IP_ADAPTER_*` bits.
+    * Interfaces that carry no unicast address are no longer reported, since both the addresses and the interface properties are now enumerated from the unicast address table. (LocalIP, Windows)
+* libpulse and libddcutil are no longer used on Linux. Package managers should remove them from their fastfetch package.
+* QuickJS format scripting has been removed (deprecated in v2.69.0). Migrate scripts to Lua if necessary. (General)
+* The Command module option `useStdErr` has been replaced with `useOutput`, which selects which of the command's output streams to capture: `"stdout"`, `"stderr"` or `"both"`.
+    * It defaults to `"both"`, so a command that logs to stderr now has that output captured instead of discarded.
+    * Set it to `"stdout"` or `"stderr"` to restore the old single-stream behavior. (Command)
+* The Shell module now reports the shell from the password database (`/etc/passwd`) instead of the `$SHELL` environment variable, which may differ when the login shell was changed after the session started. (Title)
+* The Disk custom format no longer provides `{size-available}`. `{size-free}` now reports whichever of the two the `disk.useAvailable` option selects, and the raw byte counts are available as `{bytes-used}` and `{bytes-total}`. (Disk)
+    * This also means `{size-free}` now changes with `disk.useAvailable`; it used to always report the file system's free size.
+* The Disk JSON output no longer includes `bytes.available` and `bytes.used`. (Disk)
+    * `bytes.free` and `bytes.total` are unchanged; the used size can be derived as `total - free`.
+
+Features:
+* Added Sound detection on Android. (Sound, Android)
+* Added display detection on Android over binder, which needs neither a child process nor a permission. (Display, Android)
+* Added battery temperature, remaining time and charger type (AC / USB / wireless) detection on Android. (Battery, Android)
+* Added media detection on Android when fastfetch runs as an app UID. (Media, Android)
+    * Requires `Notification access` permission
+* Added app display-name detection on Android, so the media module names the player the way the app names itself instead of by its package name, and the terminal module reports the label Termux is installed under. (Media, Terminal, Android)
+* Performance improvements & internal cleanups
+* Added Finnish language support. (General)
+* Added pkgsrc package detection on macOS. (#2627, Packages, Apple)
+* Added an ALSA fallback to Sound on Linux, so a machine that runs no sound server reports its output device and volume instead of an error. (Sound, Linux)
+
+Bugfixes:
+* Fixed `--config`/`-c` bash completion offering one candidate per word instead of one candidate per file for paths containing spaces. (Completion, Bash)
+* Fixed external monitors detected via DDC/CI being randomly reported as built-in on Linux. (#2615, Brightness, Linux)
+* Fixed the Vulkan driver name being concatenated with the name of a previously enumerated device on multi-GPU systems. (#2619, Vulkan)
+* Fixed the foot terminal font size not being parsed when written as `Font Name-size`, e.g. `Berkeley Mono-12`. (#2624, TerminalFont, Linux)
+* Fixed `/boot` being hidden by default on Haiku, where it is the system volume. (Disk, Haiku)
+* Improved Snapdragon X1/X2 model name detection on Linux. (#2625, CPU, Linux)
+* Fixed the Android build failing with `GL/gl.h` not found, because the NDK ships the EGL headers that turned OpenGL detection on but not the desktop GL headers it includes. (OpenGL, Android)
+* Fixed MAC address reporting `02:00:00:00:00:00` on macOS 27. (LocalIP, Apple)
+* Fixed assertion failure when percentage exceeds 100. (Percent)
+* Fixed a non-existent command being reported as a generic child process error on Windows instead of `command not found`. (Command, Windows)
+* Fixed Android display detection on devices running Android 17. (Display, Android)
+* Fixed Windows volumes with a per-user quota (such as network shares) reporting a wrong total size and a wrapped-around used size, because the total size was quota-limited while the free size was not. (#2651, Disk, Windows)
+    * On Windows 10 1809 (build 17763) and later, the whole volume's capacity and free space are now reported by default. Set `disk.useAvailable` to `true` to keep reporting the space that is available to the current user, quota included.
+
+Logos:
+* Added filled Artix logo (#2631)
+* Renamed PostmarketOS to nura (#2626)
+
+# 2.69.0
+
+Changes:
+* ImageMagick 6 is deprecated and will be removed in a future release. It remains available for older Debian and Ubuntu releases; upgrade to ImageMagick 7 when possible.
+* The experimental QuickJS format scripting is deprecated, disabled by default, and planned for removal in the next release. Re-enable it with `cmake -DENABLE_QUICKJS=ON`, or migrate scripts to Lua. (General)
+* Replaced `--logo-recache` and `logo.recache` with `--logo-cache` and `logo.cache`. Use `true` to reuse or create valid cache entries, `false` to disable caching, or `regen` to force regeneration. (Logo)
+* Modules selected with `--structure` now honor their options from the JSON config.
+
+Features:
+* Added `logo.position: "auto"` and `--logo-position auto` to place wide logos above module output when the terminal has less than 32 columns available for text. (Logo)
+    * The position can also be selected in interactive `--gen-config`. 
+    * For now, the default position is `left` for compatibility with previous releases. This may change to `auto` in future releases.
+* Improved Bluetooth detection support:
+    * Added Bluetooth Low Energy detection on Windows and macOS.
+    * Report device type (LE or classic) and signal quality, if available.
+    * Added Bluetooth Core 6.0–6.3 version reporting. (BluetoothRadio)
+* Improved image log support:
+    * Image logos on Windows, macOS, and Android now use native image processing libraries instead of ImageMagick. 
+        * For package managers: ImageMagick dependencies can be removed on macOS, Windows and Android as they are no longer used for image logos.
+        * Windows Terminal supports sixel logos out of the box
+    * Changes to a source image now correctly invalidate its cache. (Logo)
+    * Added GIF and APNG support to `--kitty` image protocol. Set `logo.animationFrame` to `0` to play animations in compatible kitty terminals; positive or negative values select a still frame. Android animation requires Android 12 (API 31); terminals without kitty graphics protocol support report an error and fall back to the built-in logo instead. (Logo)
+    * Added cmake option `-DENABLE_IMAGE_LOGO=<BOOL>` (default `ON`) to disable image logos and reduce binary size. `raw` logos remain available. (Logo)
+* Improved Linux support:
+    * Added RakuOS rum overlay package counting (`{rum}`) and CRUX package detection (`{crux}`). (Packages)
+    * Added CPU name and frequency detection on SPARC. (CPU)
+    * Improved COSMIC version detection and added Umbriel version detection. (DE / WM)
+* Improved Android support:
+    * Expanded ROM detection to HarmonyOS, Flyme, OneUI, LineageOS, and many other ROMs. (DE)
+    * Improved camera detection; Android 7 (API 24) or later is required. (Camera)
+    * Battery level and charging state are now available to apps; detailed battery information requires root or ADB. (Battery)
+    * Added display mode, physical size, rotation, and HDR information. App-based detection requires Android 13 (API 33); root or ADB can also detect displays on older versions. (Display)
+    * Added Wi-Fi interface, connection, standard, and security information. Android 11 (API 30) or later is required. Termux:API is needed for the Wi-Fi permission, and location permission is needed to reveal SSID and BSSID; without location permission the two names appear as `<redacted>`. (Wifi)
+    * Added Wallpaper detection, which effectively reports `/data/system/users/0/wallpaper`. (Wallpaper)
+    * Added Media detection, root/ADB only. (Media / Player)
+* Improved macOS support:
+    * Improved process-name detection in Top. (Top)
+    * Improved wallpaper detection on macOS Sonoma and later. (#2559, Wallpaper)
+* Improved Windows support:
+    * `winget` now counts packages from configured sources, excludes Microsoft Store apps, and caches results. It remains disabled by default. (Packages)
+    * Player names now match the names shown by Windows (for example, Chrome is reported as Google Chrome). (Player)
+* Added battery-level detection for more controllers on Windows and macOS. (Gamepad)
+* Improved macOS controller name detection (macOS, Gamepad)
+    * macOS controller names now match the system; configs that filter by name may need updating.
+    * Requires macOS 11 or later.
+* Improved the built-in HTTP client used by PublicIP and Weather; it now supports custom ports and chunked responses. (PublicIP / Weather)
+* Reduced the default `waitTime` for DiskIO, NetIO, and Top from 500 ms to 250 ms. (DiskIO / NetIO / Top)
+* Added `general.preload.lua` for loading shared Lua helpers before modules run. It requires a Lua-enabled build and starts the Lua interpreter whenever configured. (General)
+    * Lua format scripting is now considered stable.
+
+Bugfixes:
+* Fixed Snapdragon X2 series model detection on Linux. (#2611, CPU / Linux)
+* Fixed image logo caching, padding, and positioning issues, including an iTerm display bug. (Logo)
+* Fixed several Windows issues, including Windows Terminal font detection, redirected `--gen-config` output, and gamepad battery reporting for DualShock 4 and Switch controllers. (#2573, TerminalFont; Gamepad; General)
+* Fixed formatting and display issues, including ANSI-aware truncation, date/time formatting, and bright key/title colors. (Format / DateTime / Display)
+* Fixed `--dynamic-interval` retries and stale results across multiple rounds. (PublicIP / Weather / Display / Monitor / WM / DE / Media / Player / Shell / Terminal)
+* Fixed invalid numeric and color options that could cause hangs or excessive output. (Separator / CPUUsage / NetIO / DiskIO / LoadAvg / Colors)
+* Fixed JSON output and config validation across several modules, including GPU, Btrfs, Gamepad, Packages, and Custom. (General)
+* Fixed GPU memory and device-type reporting, GNOME Classic and Trinity version detection, and default-route family names. (GPU / DE / LocalIP)
+* Fixed module output and filtering issues affecting editor failures, sound status, command selection, and ignored keyboard/gamepad devices. (Editor / Sound / Command / Keyboard / Gamepad)
+* Fixed package counting with read-only databases and corrected other package detection and JSON output issues. (Packages)
+* Fixed Base64 encoding, big-endian handling, and 64-bit value truncation on 32-bit platforms. (General)
+
+Logos:
+* Added ALT Atomic
+* Removed Zerene
+
+# 2.68.1
+
+Changes:
+* The DE / WM / LM modules now reports the full name "Desktop Environment" / "Window Manager" / "Login Manager" instead of the abbreviations.
+
+Features:
+* Improved Login Manager (LM) module
+    * Added support on macOS, Windows and POSIX systems without systemd (by process list enumeration).
+    * Reports pretty name on Linux.
+* Added Top module to print processes with the highest CPU, memory or disk I/O usage. (Top)
+* Added module key localization support. (General)
+    * Added a new option `--key-language <?lang>` (`display.key.language: "<?lang>"` in JSON config). When left empty, it defaults to the system locale.
+    * See `fastfetch -h key-language` for all supported languages.
+    * Exposed in custom key format as `{module-name}`.
+* Improved Wi-Fi module
+    * Added Wifi channel width detection, exposed via `{channel-width}` in custom format (reports 0 when not supported).
+    * Improved Wifi channel frequency accuracy and fortified detection on Windows, macOS.
+    * Added Wifi detection support on SunOS, Haiku.
+* Added Battery detection support on SunOS. (Battery, SunOS)
+* Added terminal font size detection support on Termux. (TerminalFont, Android)
+* Improved GTK theme/icons/font detection on standalone WMs such as Hyprland, sway, niri and i3. (Theme, Linux)
+* Improved fish completion scripts to print enum descriptions. (Completion)
+* Enabled Wayland support on Android. (DisplayServer, Android)
+* Added DE detection support for ASUS Zenfone. (DE, Android)
+* Added new ARM SoCs (CPU, Linux / Android)
+
+Bugfixes:
+* Fixed I/O rate calculation precision in DiskIO and NetIO, and prevented division by zero. (DiskIO / NetIO)
+* Fixed the fast path of ash version detection. (Shell)
+* Fixed memory usage detection support on x86-32 FreeBSD (Memory, FreeBSD)
+    * Note: Although 32-bit systems are still supported, they are deprecated and barely tested. Users are encouraged to upgrade to 64-bit systems.
+* Some internal cleanups and optimizations.
+* Attempted to fix potential issues on big-endian systems
+    * Not tested due to lack of access to big-endian hardware.

+
+# 2.67.1
+
+Bugfixes:
+* Fixed a `Symbol not found` error when running on macOS 10.15. (#2499, Codec, macOS)
+* Fixed Alacritty font size never being parsed from the TOML config. (#2501, TerminalFont)
+* Fixed bright colors incorrectly being active when the terminal uses a light theme. (#2509, Display)
+* Fixed Ghostty terminal font detection (TerminalFont)
+    * Now tries to load the config with the `.ghostty` extension. (#2500)
+    * Fixed `font-family` fallback order. (#2510)
+* Some internal cleanups and optimizations.
+
+Features:
+* Added a C23 compiler check so the build process gracefully exits during CMake configuration if the compiler is unsupported. (CMake)
+* Added compatibility workarounds for Apple Clang 16 to fix building on macOS 14. (CMake, macOS)
+* Reported real Android version codenames (e.g., "Baklava", "Vanilla Ice Cream") instead of "REL". (OS, Android)
+* Added Loadavg detection support on Haiku R1B6. (Loadavg, Haiku)
+* Enabled image logo support in the Zellij terminal multiplexer. (#2507, Logo)
+* Improved Locale detection on Windows (Locale, Windows)
+    * Now respects `LC_ALL` and `LANG` environment variables if set for better compatibility with MSYS2/cygwin.
+    * Appends the active system Code Page (e.g., `.UTF-8` or `.Windows-1252`) to the default system locale fallback.
+
+# 2.67.0
+
+Changes:
+* The minimum supported compiler version has been raised to GCC 13 (released on 2023-04-26) and Clang 16 (released on 2023-03-17) to accommodate the new C23 syntax used throughout the codebase. (General)
+    * As a result, building from source in Debian 12 (which only ships GCC 12 by default) is no longer supported. Users must upgrade their compiler or use the prebuilt binaries from the GitHub releases page.
+* The `general.preRun` option has been removed due to security concerns. (General)
+    * Users who relied on this option to run a command before printing output will need to move that logic to an external wrapper.
+* The `{status}` placeholder in Battery custom format is now an array type instead of a single comma-separated string. (Battery)
+    * This is a breaking change for users who print `{status}` in Lua scripts. They can use `table.concat(...)` to join the array into a single string if needed.
+* The `--gen-config-*` flags (`--gen-config-full`, `--gen-config-force`, `--gen-config-full-force`) have been removed and their functions have been merged into `--gen-config`. (Global)
+    * See features below.
+
+Features:
+* `--gen-config` now opens an interactive configuration TUI to make generating config files easier.
+    * It falls back to non-interactive generation when `$NO_COLOR` is set or when stdin/stdout is not a TTY. This behavior can also be used to disable the interactive mode.
+* Added an experimental [WebUI](https://fastfetch-cli.github.io/fastfetch-config/) ([separate project](https://github.com/fastfetch-cli/fastfetch-config)) for generating and editing configs.
+* Added `-w`/`--watch` as a seconds-based alias for `--dynamic-interval`, defaulting to 1 second when no value is provided. (#2478, Watch)
+* Added InitSystem detection on Windows, reporting the first userland process (`smss.exe`). (InitSystem, Windows)
+* Added CPU and GPU temperature detection support for Apple M5 series chips. (CPU / GPU, macOS)
+* Reported `Basic` as the Windows theme when DWM is disabled. (Theme, Windows)
+* Improved Ghostty terminal font detection performance. (#2122, TerminalFont)
+    * It now parses Ghostty directly instead of running `ghostty +show-config`.
+* Added support for a wider range of TOML config syntaxes used by Alacritty. (#2456, TerminalFont)
+
+Bugfixes:
+* Fixed a potential fish version detection error. (Shell, Linux)
+* Fixed incorrect resolution reporting when a monitor advertises multiple preferred modes. (#2481, Display, Linux)
+* Fixed connected monitors being missed when Wayland output events arrive late. (#2451, Display, Linux)
+* Fixed VP9 codec detection on macOS. (Codec, macOS)
+* Corrected Base64 encoding on big-endian hosts. (#2470)
+* Fixed invalid URL parsing in the PublicIP module. (PublicIP)
+* Correctly reported virtual GPUs on Windows. (#2461, GPU, Windows)
+* Added a size limit for network responses to prevent excessive memory usage and mitigate potential attacks. (PublicIP / Weather)
+* Fixed Ubuntu Studio Core detection. (OS, Linux)
+* Relaxed the HTTP response check so that both `HTTP/1.0` and `HTTP/1.1` responses are accepted when fetching data over the network. (PublicIP / Weather)
+* Various internal cleanups and optimizations:
+    * Fixed multiple memory leaks (Separator, Camera, Codec, Display).
+    * Added integer overflow checks to the string buffer implementation.
+    * Various code cleanups and compiler warning fixes.
+
+Logos:
+* Removed Hypros, MagpieOS, Furreto, EmperorOS and Magix
+
+# 2.66.0
+
+Changes:
+* CPU package count is no longer reported in the default output.
+    * Users can still print it in custom formats via `{packages}`
+
+Bugfixes:
+* Fixed compatibility with WSL 2.9.3 (#2433, WM, Linux)
+* Fixed AMD GPU names not being queried accurately in `driverSpecific` mode (GPU, Linux)
+* Fixed GPU core counting for Apple Silicon GPU on Asahi Linux (GPU, Linux)
+* Some internal cleanups and optimizations.
+
+Features:
+* Added Astra Linux version detection (OS, Linux)
+* Improved performance of Windows PowerShell version detection (Shell, Windows)
+* Improved performance of Media module on macOS (Media, macOS)
+* Added proxmox backup server detection (#2443, OS, Linux)
+
+Logos:

+
+# 2.65.2
+
+Changes:
+* Memory usage calculations now exclude the ZFS ARC cache on Linux, FreeBSD, NetBSD, and SunOS. (#1995 / #2418, Memory)
+    * This prevents the Memory module from reporting artificially high memory usage on systems with the ZFS kmod enabled.
+
+Bugfixes:
+* The GPU module no longer pings sleeping dedicated GPUs on dual-GPU laptops. (#2419, GPU)
+    * As a result, PCIe link speed detection (introduced in v2.65.0) is now only enabled in `driverSpecific` mode.
+* Fixed a crash when detecting hardware codec support with the `amdgpu` driver on Linux. (#2419, Codec, Linux)
+
+Logos:
+* Updated CachyOS_small; fixed CachyOS logo colors to match the official logo better
+* Added Turkish
+
+# 2.65.1
+
+No changes
+
+# 2.65.0
+
+Changes:
+* `display.disableLinewrap` now defaults to `false`.
+    * This allows long lines to wrap instead of being truncated, preventing confusion for new users.
+    * Wrapped lines may overlap with the image logo. Users who prefer the old behavior can set `display.disableLinewrap: true` in their config file or use `--disable-linewrap true` on the command line.
+* Reorders package manager variables in custom format strings, moving aggregate variables (e.g., `all`, `brew-all`, `flatpak-all`) to the end. (Packages)
+    * This is a breaking change for users relying on numeric placeholders (e.g., `{1}`). Numeric placeholders are a long-deprecated feature; named placeholders (e.g., `{pacman}`) are always preferred and future-proof.
+* Enables `showPeCoreCount` by default to better display hybrid-architecture core counts. (CPU)
+* No longer accepts `chafa` options in config files if `chafa` support was disabled at compile time. (Logo)
+    * This may affect users who generated their config files using `fastfetch --gen-full-config`. To resolve this, simply remove the `chafa` section from the config file.
+
+Features:
+* Adds detection for CPU code names (e.g., "Alder Lake", "Zen 4") and manufacturing technologies (e.g., "Intel 7", "TSMC N4") on x86 processors. (#1501, CPU, X86)
+    * These can be used in custom formats via `{code-name}` and `{technology}`.
+* Adds PCIe link speed detection (current and max generation & lanes) for GPUs on Linux and Windows.
+    * These can be used in custom formats via `{pcie-max-speed}` and `{pcie-curr-speed}`.
+* Adds HDR display detection via the `wp-color-management-v1` Wayland protocol. (#2356, Display, Linux)
+    * Previously, HDR detection was only supported on KDE Plasma.
+* Adds the `egl-ext` detection method, which uses `EGL_EXT_device_enumeration` for GPU enumeration. (GPU)
+* Adds terminal version and font detection for `kmscon`. (#2393, Terminal / TerminalFont, Linux)
+* Adds the currently-in-beta code name "Golden Gate" for macOS 27. (OS, macOS)
+* Adds WPA version detection on FreeBSD. (Wifi, FreeBSD)
+* Adds package manager support for `porg` (#2405) and `install-release` (#2342). (Packages, Linux)
+* Adds Weston version detection. (WM, Linux)
+* Improves the core type (P-Core/E-Core) fetching mechanism on Windows by using `EfficiencyClass` instead of legacy frequency inference. (CPU, Windows)
+* Improves display detection compatibility with KDE 6.7. (Display, Linux)
+* Improves display serial number detection, now preferring alphanumeric serial numbers when available. (Display)
+    * This can be used in custom formats via `{serial}`.
+* Improves the performance of `emerge` package manager detection. (#2406, Packages, Linux)
+* Improves error messages for config file parsing errors.
+* Improves reliability of the `Codec` module on Linux (Codec, Linux)
+    * Adds `va-x11` backend for VA-API and VDPAU, which is used if `va-drm` backend fails to initialize.
+    * Fixes an issue where the Codec module incorrectly reports no results when the `codec.showType` option is set.
+
+Bugfixes:
+* Fixes physical core detection on non-x86 architectures and simplifies the frequency detection code. (CPU, Linux)
+* Fixes console mode and output code page initialization issues when running `fastfetch` in `Conhost`. (#2383, Windows)
+* Fixes public IP detection randomly failing on Linux. (#2401, PublicIP, Linux)
+* Fixes several memory leaks.
+
+Logos:
+* Adds Zerene OS. (#2404)
+
+# 2.64.2
+

+* Fixes image rendering being wiped quickly (#2374)
+    * Regression from v2.64.0
+* Fixes ASCII logo being overwritten in `--dynamic-interval` mode
+    * Regression from v2.64.0
+
+Logos:
+* Updates OpenWrt and adds a small variant (#2376)
+    * The old one is renamed to `openwrt_old`
+
+# 2.64.1
+
+Features:
+* Adds a CMake option `-DPACKAGES_REMOVE_DISABLED` to remove detection code of disabled packages (`-DPACKAGES_DISABLE_<PACKAGE_NAME>`) for slightly smaller binary size (Packages)
+
+Bugfixes:
+* Fixes compatibility issues with Lua 5.3
+* Avoid possible infinite recursion in `encode_json` when encoding deeply nested tables or circular references
+* Fixes compilation issues when building with old macOS SDKs
+
+# 2.64.0
+
+New **optional build** dependencies:
+* [`libva`](https://github.com/intel/libva) and [`libvdpau`](https://www.freedesktop.org/wiki/Software/VDPAU) for the new `Codec` module.
+* [Lua 5.3 to 5.5](https://www.lua.org/) for Lua scripting support, or [QuickJS](https://github.com/quickjs-ng/quickjs) v0.15.0 or newer for JavaScript scripting support.
+
+Features:
+* Adds `Codec` module support for Windows, macOS, Linux, and Android for hardware-accelerated video codec detection (Codec)
+    * Backends used (results may vary depending on the backend due to driver differences):
+        * Linux and BSD: VA-API (default) and VDPAU (fallback for NVIDIA). Fastfetch must be built with `libva` and `libvdpau` support to enable these backends.
+        * Windows: D3D12VA (Windows 11) and D3D11VA+MFT (Windows 10 or older)
+        * macOS: VideoToolbox
+        * Android: AMediaCodec
+        * Common: Vulkan Video (disabled by default; can be enabled with `"useVulkan": true`)
+    * By default, both encoders and decoders are reported. If no codecs are detected for a given type, `None` is reported. This behavior can be configured using the `"showType": "encoder|decoder"` option.
+* Adds experimental Lua script support for custom formats (Global)
+    * Basic usage (using `Title` as an example): `{ "type": "title", "format": "lua:return string.format('Hello %s@%s', (...).userName, (...).hostName)" }`. The `lua:` prefix indicates a Lua script. A `return` statement is required to pass the final result back to the fastfetch module; otherwise, `nil` is returned implicitly and the entire module output is skipped.
+    * Parameters are passed via variable arguments `(...)`. Users can assign them to named variables for better readability. For example: `lua:local args = ...; string.format('Hello %s@%s', args.userName, args.hostName)`.
+    * The Lua interpreter instance is shared across all modules. This allows users to store and manipulate data across modules. For example:
+        * `{ "type": "shell", "format": "lua:shell = ..." } // Note: no "return" here`
+        * `{ "type": "terminal", "format": "lua:return shell.prettyName .. ' in ' .. (...).prettyName" } // This will print the detected shell and terminal names`
+    * A `json_encode(table, is_pretty)` function has been added to the Lua API for easier debugging. For example, `lua:return json_encode(...)` will print all available variables and their values in JSON format.
+    * Supported Lua versions: Lua 5.3 to 5.5 (Lua 5.1 and LuaJIT are not supported). The Lua version is auto-detected at build time. Once built, users can check the configured Lua version using `fastfetch --list-features`.
+* Adds experimental QuickJS script support for custom formats as an alternative to Lua (Global)
+    * Basic usage: `{ "type": "title", "format": "qjs:`Hello ${this.userName}@${this.hostName}`" }`. The `qjs:` prefix indicates a JavaScript script. No `return` statement is needed; the final result is simply the evaluated value of the script.
+    * Parameters are passed via the `this` object. Usage is mostly the same as Lua, but using JavaScript syntax.
+    * Requires [quickjs-ng v0.15.0](https://github.com/quickjs-ng/quickjs/releases/tag/v0.15.0) or newer.
+* Adds CMake options `-DMODULE_DISABLE_<MODULE_NAME>=ON` to disable modules at compile time for a smaller binary size
+    * Use `cmake -L . | grep MODULE_DISABLE_` to list all available options.
+    * These options rely on LTO for dead code elimination (`-DCMAKE_BUILD_TYPE=Release` should enable LTO by default).
+* Adds the ability to remove unneeded ASCII logos without modifying the fastfetch source code, further reducing binary size
+    * Simply remove the corresponding logo file from the logo directory (`src/logo/ascii/[a-z]/*`) and re-run `cmake`.
+* Improves string manipulation specifiers in custom formats
+    * They are now ANSI escape-aware and work correctly with colored output (e.g., percentages with `num-color`) (#2364). Limitations:
+        * They are still not wide-character aware and treat CJK and emoji characters as raw bytes.
+        * Escape sequences in the middle of strings are not supported.
+    * A new `|` specifier has been added to center strings. For example, `{user-name|20}` will center the username in a 20-character-wide field.
+* Adds preliminary `Bootmgr`, `Brightness`, and `WMTheme` detection support for Haiku (#2358, Haiku)
+* Adds `Wallpaper` and `WMTheme` detection support for the COSMIC desktop environment (Linux)
+* Improves terminal name detection for Nix packages (#2352, Terminal, Linux)
+* Adds DDC/CI brightness detection support for FreeBSD (Brightness, FreeBSD)
+    * DDC/CI communication can be very slow. Users can set the `ddcciSleep: null` option to skip DDC/CI detection.
+* Reworks the built-in logo printing logic. ASCII logos and modules are now printed line by line, avoiding issues like #2239
+    * Note: Image logos are not affected by this change and still print the entire image first before printing any modules.
+* Adds a new `--logo-padding-bottom` option to control the padding between the bottom of the logo and the first module when `--logo-position top` is used
+    * Previously, `--logo-padding-right` was used for both right and bottom padding.
+* Adds `Samsung Exynos 2600` to CPU detection (CPU, Android)
+* Adds terminal font detection support for the Muxy terminal (TerminalFont, macOS)
+* Improves the performance of BusyBox (ash) version detection and always reports `ash` as the pretty name (Shell, Linux)
+
+Bugfixes:
+* Fixes SwayFX version detection (WM, Linux)
+* Fixes fallback font detection for Ghostty (TerminalFont, macOS)
+* Fixes `--stat` output to correctly align with the right border (Global)
+* Fixes boot manager on macOS 26 (mBoot) is incorrectly reported as `iBoot` (Bootmgr, macOS)
+
+Logos:
+* Adds Quasar (#2338, #2323), Origami, Origami_small (#2321, #2322), BerserkArch (#2324, #2310), and NixOS2 (#2346)
+* Minor tweaks and color fixes for the NixOS_small logo (#2357)

+Thank you for your interest in fastfetch. This document covers building, architecture, how to add a module or a logo, code style, commit conventions, and the pull request workflow.
+
+fastfetch is a system information tool written in C23, supporting Linux, macOS, Windows, the BSDs, Solaris, Haiku and Android. The project places strong emphasis on **startup time** and on keeping **dependencies optional**; many design decisions only make sense under that constraint, and this document returns to it repeatedly.

+## Contributor quick reference
+
+| Task | Start here | Verify with |
+|---|---|---|
+| Build and run fastfetch | `run.sh`, `CMakeLists.txt` | `./run.sh` |
+| Add a module | `src/modules/<name>/`, `src/detection/<name>/`, `src/modules/modules.c`, `CMakeLists.txt` | `cmake -B build && cmake --build build -j` |
+| Add a platform implementation | `src/detection/<name>/<name>_<platform>.c`, the matching platform block in `CMakeLists.txt` | Build on the target platform or CI |
+| Add an ASCII logo | `src/logo/ascii/<letter>/<name>.txt`, matching `<letter>.inc` | `./build/fastfetch --logo <name>` |
+| Change formatting or JSON output | `src/modules/<name>/<name>.c` | `./build/fastfetch -s <name> --format json` |
+| Change shared formatting or containers | `src/common/format.h`, `src/common/color.h`, `src/common/FFstrbuf.h` | Build and run the matching test |
+| Run the test suite | `tests/`, `build/` | `cd build && ctest --output-on-failure` |
+
+For a typical code change, the shortest useful iteration is: configure, build the `fastfetch` target, run the affected module, then run the tests. If you add a directory or a generated input, re-run `cmake -B build` so that CMake refreshes its file globs.
+
+---
+
+## Getting started
+
+### Building
+
+The quickest way is `run.sh` in the repository root: it creates `build/`, configures, compiles and runs the binary.
+
+```sh
+./run.sh                 # build and run
+./run.sh --format json   # arguments are forwarded to fastfetch
+```
+
+Manual build:
+
+```sh
+cmake -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo
+cmake --build build --target fastfetch -j$(nproc)
+./build/fastfetch
+```
+
+The default build type is `RelWithDebInfo`. LTO is enabled whenever `ENABLE_LTO=ON` **and** `CMAKE_BUILD_TYPE != Debug`, so the default configuration enables it and only `Debug` builds omit it. This is significant because LTO here is not merely an optimization: it is what removes the code of disabled modules. See [Pitfalls](#pitfalls).
+
+### Common build options
+
+| Option | Default | Notes |
+|---|---|---|
+| `CMAKE_BUILD_TYPE` | `RelWithDebInfo` | LTO is on for anything but `Debug` |
+| `BUILD_TESTS` | `OFF` | Builds the unit tests in `tests/` |
+| `BUILD_FLASHFETCH` | `ON` | Also builds the stripped-down `flashfetch` |
+| `BINARY_LINK_TYPE` | `dlopen` | `dlopen` / `dynamic` / `static` |
+| `ENABLE_ASAN` | `OFF` | Address Sanitizer |
+| `ENABLE_LTO` | `ON` | Link-time optimization |
+| `MODULE_DISABLE_<NAME>` | `OFF` | Disable a module, e.g. `MODULE_DISABLE_GPU=ON` |
+| `SET_TWEAK` | `ON` | Appends a tweak to the dev version; turned off for releases |
+
+`BINARY_LINK_TYPE=dlopen` (the default) is a deliberate design choice: optional dependencies (Vulkan, Wayland, DBus, ImageMagick, chafa, …) are loaded at runtime, so a missing library never prevents startup. When adding a third-party dependency, use the dlopen helpers in `common/library.h` — do not link it directly.
+
+For a minimal-dependency build, see `.github/workflows/build-no-features-test.yml`:
+
+```sh
+cmake -DBUILD_TESTS=On -DENABLE_VULKAN=OFF -DENABLE_WAYLAND=OFF -DENABLE_X11=OFF \
+      -DENABLE_DBUS=OFF -DENABLE_ZLIB=OFF ... .
+```
+
+### Dependencies
+
+Required: CMake ≥ 3.21 and a C23 compiler (GCC, Clang or MSVC). Everything else is optional.
+
+Optional dependencies are auto-detected: libpci, libdrm, vulkan, wayland, xcb, xrandr, dbus, sqlite3, rpm, imagemagick{6,7}, chafa, zlib, egl, glx, opencl, freetype, elf, libzfs, and more.

+fastfetch.c  →  options/    (global configuration)
+             →  modules/    (76 modules, formatting and output)
+             →  detection/  (one platform implementation each, raw data)
+             →  common/     (infrastructure)
+```
+
+The number of module directories does not match the number of detection directories, which is expected. The following relationships are structural rather than a fixed inventory:
+
+- **13 modules have no detection directory** — they are either pure layout (`break`, `separator`, `colors`, `title`, `logo`) or reuse another module's detection result (`display`, `monitor`, `kernel`, `shell`, `terminal`, `player`, `custom`, `datetime`).
+- **4 detection directories serve modules with different names** — `displayserver` (→ `display`, `monitor`), `gtk_qt` (→ `theme`, `icons`, `font`, `cursor`), `terminalshell` (→ `terminal`, `shell`) and `libc`.
+
+Therefore, do not assume that `modules/<x>/` always has a matching `detection/<x>/`.
+
+### Layer boundaries
+
+| Layer | Owns | Must not |
+|---|---|---|
+| `options/` | **Global** config (colors, logo, threading, timeouts) | hold per-module options |
+| `modules/` | formatting, printing, JSON serialization | read `/proc`, call Win32 APIs, parse sysfs |
+| `detection/` | cross-platform data retrieval, clean result structs | print anything, read display config |
+| `common/` | general-purpose utilities, no business logic | depend on a specific module |
+
+A simple check: **no file under `detection/` should contain `printf` or read `instance.config`.** Symmetrically, no file under `modules/` should contain `#ifdef __linux__`.
+
+---
+
+## Core architecture: modules vs. detection
+
+This is the most important convention in the codebase. Every feature consists of a fixed set of files; using CPU as the example:
+
+```
+modules/cpu/option.h           module option struct
+modules/cpu/cpu.c              formatting and output
+detection/cpu/cpu.h            platform-independent interface
+detection/cpu/cpu_linux.c     ┐
+detection/cpu/cpu_apple.c     │
+detection/cpu/cpu_windows.c   ├─ platform implementations, one linked per build
+detection/cpu/cpu_bsd.c       │
+detection/cpu/cpu_nosupport.c ┘
+```
+
+The interface is deliberately minimal, typically consisting of only two declarations:
+
+```c
+typedef struct FFCPUResult { ... } FFCPUResult;   // result struct
+const char* ffDetectCPU(const FFCPUOptions* options, FFCPUResult* cpu);
+```
+
+The `const char*` return value is an **error string**; `nullptr` means success. This pattern is used throughout `detection/` — please keep it consistent.
+
+Helper functions are only exposed when they are genuinely shared between platform implementations (as in `cpu.h`: `ffCPUAppleCodeToName`, `ffCPUDetectByCpuid`).
+
+**The benefit of this separation:** adding a platform never touches `modules/`; fixing output formatting never touches `detection/`.
+
+---
+
+## Module registration
+
+### The descriptor
+
+Every module exports one `FFModuleBaseInfo` (defined in `common/option.h:46`) — essentially a hand-written vtable:
+
+```c
+typedef struct FFModuleBaseInfo {
+    const char* name;                    // lookup key, e.g. "cpu"
+    const char* description;             // help text
+    FFModuleDisplayName displayName;     // module name in 20 languages
+
+    void (*initOptions)(void* options);
+    void (*destroyOptions)(void* options);
+    void (*parseJsonObject)(void* options, struct yyjson_val* module);
+    bool (*printModule)(void* options);
+    bool (*generateJsonResult)(void* options, yyjson_mut_doc*, yyjson_mut_val*);
+    void (*generateJsonConfig)(void* options, yyjson_mut_doc*, yyjson_mut_val*);
+
+    FFModuleFormatArgList formatArgs;    // format placeholder table
+    const uint8_t defaultOrder;          // sort weight
+} FFModuleBaseInfo;
+```
+
+The source comment acknowledges that this is undefined behavior, since `void*` is not compatible with `FF*Options*`. It is a pragmatic compromise to obtain polymorphism in C; do not attempt to "fix" it.
+
+### The registry: a first-letter hash bucket
+
+`src/modules/modules.c` defines 26 `static FFModuleBaseInfo*` arrays (`A[]` through `Z[]`), each terminated by `nullptr`, collected into `ffModuleInfos[26]`:
+
+```c
+FFModuleBaseInfo** modules = ffModuleInfos[toupper(name[0]) - 'A'];  // O(1) bucket lookup
+for (; *modules; ++modules) {                                        // linear scan in the bucket
+    if (ffStrEqualsIgnCase(name, (*modules)->name)) { ... }
+}
+```
+
+Because the registry is small, a single arithmetic bucket lookup followed by a few string comparisons is preferable to a general-purpose hash table. When adding a module, place its descriptor in the bucket matching the first letter of `.name`, and keep the existing `nullptr` terminator at the end.
+
+### The calling convention: zero heap allocation
+
+Every dispatch site (`jsonconfig.c:98`, `commandoption.c:189`) follows the same pattern:
+
+```c
+alignas(uint64_t) uint8_t optionBuf[FF_OPTION_MAX_SIZE];  // 256 bytes, on the stack
+baseInfo->initOptions(optionBuf);
+baseInfo->parseJsonObject(optionBuf, jsonVal);             // JSONC path only
+baseInfo->printModule(optionBuf);                          // or generateJsonResult
+baseInfo->destroyOptions(optionBuf);
+```
+
+`FF_OPTION_MAX_SIZE = 1 << 8` (256 bytes). Every module's `option.h` must end with:
+
+```c
+static_assert(sizeof(FFCPUOptions) <= FF_OPTION_MAX_SIZE, "FFCPUOptions size exceeds maximum allowed size");
+```
+
+**In other words, no module option struct may exceed 256 bytes.** This is a hard constraint, enforced at compile time.
+
+The three dispatch entry points:
+
+| Entry point | Location | Used for |
+|---|---|---|
+| `parseModuleJsonObject` | `common/impl/jsonconfig.c:90` | the `modules[]` array in a JSONC config |
+| `parseStructureCommand` | `common/impl/commandoption.c:181` | the colon-separated structure string |
+
+### Build-time module discovery
+
+`CMakeLists.txt:134` globs `src/modules/*/*.c`, keeps only the entries whose file name matches their directory name, and generates a `MODULE_DISABLE_<UPPER>` option for each:
+
+```cmake
+file(GLOB FF_MODULE_SRCS CONFIGURE_DEPENDS RELATIVE "..." ".../src/modules/*/*.c")
+set(FF_MODULE_DIRS "")
+foreach(FF_MODULE_SRC ${FF_MODULE_SRCS})
+    get_filename_component(FF_MODULE_DIR "${FF_MODULE_SRC}" DIRECTORY)
+    get_filename_component(FF_MODULE_NAME "${FF_MODULE_SRC}" NAME_WE)
+    if("${FF_MODULE_DIR}" STREQUAL "${FF_MODULE_NAME}")
+        list(APPEND FF_MODULE_DIRS "${FF_MODULE_DIR}")
+    endif()
+endforeach()
+
+foreach(FF_MODULE_DIR ${FF_MODULE_DIRS})
+    string(TOUPPER "${FF_MODULE_DIR}" FF_MODULE_UPPER)
+    option(MODULE_DISABLE_${FF_MODULE_UPPER} "Disable module ${FF_MODULE_DIR}" OFF)
+endforeach()
+```
+
+Because the glob matches sources rather than directories, a directory counts as a module only when `src/modules/<name>/<name>.c` exists. Empty directories — which git does not track, so they are easy to leave behind — and stray files are ignored instead of breaking the configure step with `Cannot find source file`.
+
+### Module sources are discovered automatically
+
+`FF_MODULE_DIRS` also drives the source list (`CMakeLists.txt:516`):
+
+```cmake
+foreach(FF_MODULE_DIR ${FF_MODULE_DIRS})
+    list(APPEND LIBFASTFETCH_SRC
+        src/modules/${FF_MODULE_DIR}/${FF_MODULE_DIR}.c
+    )
+endforeach()
+```
+
+Consequences:
+
+- `src/modules/<name>/<name>.c` is compiled as soon as the file exists — **there is no source list to edit for the module layer**.
+- The file name must match the directory name. A directory whose `.c` file is named differently, or has none at all, is silently not a module: a typo therefore shows up as a module missing from `fastfetch --list-modules`, not as a build error.
+- The glob uses `CONFIGURE_DEPENDS`, so with the Makefile and Ninja generators the build re-evaluates it and re-runs CMake when a module source is added or removed. With other generators, or to be safe, re-run `cmake -B build` explicitly.
+
+Only the module layer is automated. Sources under `src/detection/` and `src/common/impl/` are **not** globbed and must still be listed by hand — see [step 5](#5-add-the-platform-sources-to-cmakeliststxt).
+

+
+## Walkthrough: adding a module
+
+Adding a `Foo` module, step by step.
+
+### 1. Define the option struct
+
+`src/modules/foo/option.h`:
+
+```c
+#pragma once
+
+#include "common/option.h"
+
+typedef struct FFFooOptions {
+    FFModuleArgs moduleArgs;   // must be the first field
+    bool showBar;
+} FFFooOptions;
+
+static_assert(sizeof(FFFooOptions) <= FF_OPTION_MAX_SIZE, "FFFooOptions size exceeds maximum allowed size");
+```
+
+`FFModuleArgs` must come first. It provides `key`, `format`, `outputColor`, `keyColor`, `keyIcon` and `keyWidth`; because it is the first field, `ffJsonConfigParseModuleArgs()` handles these generically, **so no parsing code is required**.
+
+### 2. Implement detection
+
+`src/detection/foo/foo.h`:
+
+```c
+#pragma once
+#include "fastfetch.h"
+
+typedef struct FFFooResult {
+    FFstrbuf name;
+    uint32_t count;
+} FFFooResult;
+
+const char* ffDetectFoo(const FFFooOptions* options, FFFooResult* result);
+```
+
+`src/detection/foo/foo_linux.c`:
+
+```c
+#include "foo.h"
+
+const char* ffDetectFoo(const FFFooOptions* options, FFFooResult* result) {
+    // read /sys, /proc, sysfs, dbus, ...
+    return nullptr;  // success; return an error string on failure
+}
+```
+
+**Write one file per target platform, plus a `foo_nosupport.c` fallback for the remaining platforms.** The repository currently contains 45 `*_nosupport.c` files serving this purpose.
+
+### 3. Implement the module
+
+`src/modules/foo/foo.c` — implement the six functions, then define the descriptor:
+
+```c
+FFModuleBaseInfo ffFooModuleInfo = {
+    .name = "Foo",
+    .description = "Print foo information",
+    .displayName = {
+        .en = "Foo", .ar = "Foo", .cs = "Foo", .de = "Foo", .es = "Foo",
+        .fr = "Foo", .gl = "Foo", .he = "Foo", .id = "Foo", .it = "Foo",
+        .ja = "Foo", .ko = "Foo", .pl = "Foo", .pt = "Foo", .ru = "Foo",
+        .tr = "Foo", .uk = "Foo", .vi = "Foo", .zh_CN = "Foo", .zh_TW = "Foo",
+    },
+    .initOptions = (void*) ffInitFooOptions,
+    .destroyOptions = (void*) ffDestroyFooOptions,
+    .parseJsonObject = (void*) ffParseFooJsonObject,
+    .printModule = (void*) ffPrintFoo,
+    .generateJsonResult = (void*) ffGenerateFooJsonResult,
+    .generateJsonConfig = (void*) ffGenerateFooJsonConfig,
+    .formatArgs = FF_FORMAT_ARG_LIST(((FFModuleFormatArg[]) {
+        { "Name", "name" },
+        { "Count", "count" },
+    })),
+    .defaultOrder = 73,
+};
+```
+
+Points to note:
+
+- **`displayName`** is a literal block of all 20 language fields; there is no shortcut macro, so copy the layout from an existing module: **`en`, `ar`, `cs`, `de`, `es`, `fr`, `gl`, `he`, `id`, `it`, `ja`, `ko`, `pl`, `pt`, `ru`, `tr`, `uk`, `vi`, `zh_CN`, `zh_TW`**.
+  **Fill in all 20.** The struct is read by byte offset (see [Pitfalls](#6-localization-uses-byte-offsets-not-enums)) and there is **no fallback** — a missing field means the key prints empty in that language.
+- **`formatArgs`** must be exhaustive. It drives the placeholder list printed by `fastfetch -h foo-format`; **any placeholder omitted here is neither listed nor usable by the user.**
+- The `moduleFormat` section in `doc/json_schema.json` is generated by `fastfetch -h format-json`. Its metadata comes from `FFModuleBaseInfo::formatArgs`. To keep the schema and module descriptors consistent, do not edit the `moduleFormat` section in `doc/json_schema.json` by hand; update the module metadata and regenerate it instead.
+- **`defaultOrder`**: use the current maximum plus 1. Search the existing descriptors for `.defaultOrder =` before choosing a value; do not copy a hard-coded value from this document. Leaving it out, or setting it to `0`, excludes the module from the interactive `--gen-config` picker. Only `logo`, `command` and `custom` rely on this behavior, because they require user arguments or are invoked directly by the display layer.
+
+### 4. Register it
+
+- Add `#include "modules/foo/foo.h"` to `src/modules/modules.h`
+- Insert into the `F[]` array in `src/modules/modules.c`:
+
+```c
+#if !FF_MODULE_DISABLE_FOO
+    &ffFooModuleInfo,
+#endif
+```
+
+`FF_MODULE_DISABLE_FOO` is generated by CMake — you do not define it yourself.
+
+### 5. Add the platform sources to `CMakeLists.txt`
+
+The module layer is discovered by glob (see [Build-time module discovery](#module-sources-are-discovered-automatically)), **but `src/detection/**` and `src/common/impl/**` are not**. `CMakeLists.txt` lists them explicitly, inside one mutually exclusive chain of platform blocks:
+
+| Block | Line | Covers |
+|---|---|---|
+| `if(LINUX)` | `CMakeLists.txt:522` | Linux |
+| `elseif(ANDROID)` | `CMakeLists.txt:608` | Android (Termux) |
+| `elseif(FreeBSD)` | `CMakeLists.txt:691` | FreeBSD, MidnightBSD, DragonFly |
+| `elseif(NetBSD)` | `CMakeLists.txt:788` | NetBSD |
+| `elseif(OpenBSD)` | `CMakeLists.txt:872` | OpenBSD |
+| `elseif(APPLE)` | `CMakeLists.txt:959` | macOS / iOS |
+| `elseif(WIN32)` | `CMakeLists.txt:1046` | Windows |
+| `elseif(SunOS)` | `CMakeLists.txt:1121` | Solaris / illumos |
+| `elseif(Haiku)` | `CMakeLists.txt:1204` | Haiku |
+| `elseif(GNU)` | `CMakeLists.txt:1282` | GNU/Hurd |
+
+Add the platform implementation to every block whose platform it supports, and `foo_nosupport.c` to every remaining block, so that all ten platforms still link:
+
+```cmake
+elseif(FreeBSD)
+    list(APPEND LIBFASTFETCH_SRC
+        ...
+        src/detection/foo/foo_bsd.c
+    )
+```
+
+Points to note:
+
+- Exactly one block is compiled per build, so a file omitted from a block does not exist for that platform, and the link fails with an undefined reference to `ffDetectFoo()` — **on that platform only**. A missing entry therefore builds fine locally and fails in CI; this is why every block must be covered.
+- A platform may reuse another platform's implementation instead of a stub. `src/common/impl/networking_linux.c`, for example, is listed in nine of the ten blocks (all but `WIN32`). Check where the closest sibling module points before adding a new file.
+- `DragonFly` is handled by the inner `if(DragonFly)` sub-block inside the FreeBSD block (`CMakeLists.txt:773`); add the variant there, as `processes`, `top` and `wifi` do.
+- New helpers under `src/common/impl/` follow the same rule: they are not globbed, and each block that needs one must list it.
+- A few files are appended outside the platform chain because they depend on an option or on a specific feature — for example the proprietary GPU backends (`CMakeLists.txt:1379`) and `src/common/impl/wcwidth.c` (`CMakeLists.txt:1408`). Those are written by hand as well.
+
+### 6. Modules that need warm-up
+
+If your module needs a sampling interval (CPU usage) or a network round-trip (public IP, weather), also implement `ffPrepareFoo()` and register it in the switch inside `ffPrepareCommandOption()` in `common/impl/commandoption.c`, under the matching first-letter `case`. Six modules currently do this: CPUUsage, DiskIO, NetIO, PublicIP, Top and Weather.
+
+### 7. Verify
+
+```sh
+cmake -B build && cmake --build build -j
+./build/fastfetch -s foo --format json    # JSON output
+./build/fastfetch -h foo-format           # list formatArgs placeholders
+./build/fastfetch --gen-config            # confirm it appears in the picker
+```
+
+Note the `-format` suffix on the help flag: `fastfetch -h foo` is not supported; only `fastfetch -h foo-format` works.
+
+If you added detection sources, re-check [step 5](#5-add-the-platform-sources-to-cmakeliststxt) before pushing: a platform block you missed compiles fine locally and fails only when that platform is built.
+

+
+## Walkthrough: adding a logo
+
+A new logo **must** have a corresponding "Logo Request" issue, linked from the PR with `Closes #1234`. Logo PRs without a linked issue are not accepted.
+
+### 1. Add the ASCII file
+
+```
+src/logo/ascii/<first-letter>/<distro>.txt
+```
+
+For example `src/logo/ascii/d/distro.txt`. Directories are already split by first letter (`a/` … `z/`, plus `_/`).
+
+The file is plain ASCII art with `$1` … `$9` as color placeholders:
+
+```
+                 $3 ,-^-___
+$3                /\\\///
+$2refined.$1       /\\\\//
+```
+
+- `$1` … `$9` map to palette slots 1–9; at most 9 are supported (`FASTFETCH_LOGO_MAX_COLORS = 9`)
+- `$$` is a literal `$`
+- Characters without a placeholder inherit the current color. Of the 530 existing logos, 239 use no placeholders at all (monochrome) and 291 do; **new logos should use placeholders**, as monochrome is a legacy style
+- Tabs are expanded to 4 spaces
+- Colors can be overridden with `--logo-color-1` … `--logo-color-9`
+
+### 2. Register it in the `.inc`
+
+CMake turns each `.txt` file into a `FASTFETCH_DATATEXT_LOGO_<UPPERCASE>` macro (`CMakeLists.txt:418`), but **the registry itself is maintained by hand**. Edit `src/logo/ascii/<first-letter>.inc`:
+
+```c
+// src/logo/ascii/d.inc
+
+#ifdef FASTFETCH_DATATEXT_LOGO_DISTRO
+// Distro
+{
+    .names = { "Distro" }, // ID (preferred) or NAME from /etc/os-release, do NOT add both
+    .lines = FASTFETCH_DATATEXT_LOGO_DISTRO,
+    .colors = {
+        FF_COLOR_FG_PRIMARY, // recommended for using as WHITE replacement, light-theme terminal friendly
+        FF_COLOR_FG_BLUE, // preferred
+        FF_COLOR_FG_256 "34",
+        FF_COLOR_FG_RGB "0;255;0", // not recommended because of bad compatibility with raw TTY
+    },
+},
+#endif
+```
+
+- `names` is matched case-insensitively. Do not add names that differ only by case, because they can never be distinguished. Every name is also shown by `--list-logos`, so use user-friendly spelling such as an initial capital where appropriate.
+- For a new logo, use exactly one name unless there is a specific compatibility reason to add more. That name should first be the `ID` from `/etc/os-release`. If the ID cannot distinguish this logo from another logo for the same OS, use the `NAME` value instead. `logoGetBuiltinDetected` in `src/logo/logo.c` documents the detection order: `ID`, then `NAME`, then tokens from `ID_LIKE`, then the platform name fallback. Manual `logo-source` selection uses the name directly.
+- `colors` is positional — entry 0 is `$1`, entry 1 is `$2`, and so on
+- `colors[0]` also becomes the title color and `colors[1]` the key color, unless the user overrides them
+
+If the same OS has multiple logo variants, mark the variant explicitly with `.type`:
+
+```c
+.type = FF_LOGO_LINE_TYPE_SMALL_BIT,
+```
+
+Use `FF_LOGO_LINE_TYPE_ALTER_BIT` for an alternate logo, `FF_LOGO_LINE_TYPE_SMALL_BIT` for a small logo, or combine the flags when both apply. This is also a lookup optimization: a logo marked `FF_LOGO_LINE_TYPE_SMALL_BIT` is considered only for `type = small`, while a logo marked `FF_LOGO_LINE_TYPE_ALTER_BIT` is never selected by automatic detection. Alternate logos are available only when explicitly requested through `-l <source>`.
+
+### 3. Verify
+
+```sh
+./build/fastfetch -l distro
+./build/fastfetch --list-logos | grep -i distro
+```
+
+---
+
+## Platform conventions
+
+The `detection/` layer picks its implementation by **filename suffix**; the choice is made at build time from `CMAKE_SYSTEM_NAME`:
+
+| Suffix | Platform |
+|---|---|
+| `_linux.c` | Linux |
+| `_apple.c` / `_apple.m` | macOS / iOS (`.m` for Objective-C) |
+| `_windows.c` / `_windows.cpp` | Windows (`.cpp` for WinRT / WMI) |
+| `_bsd.c` | FreeBSD |
+| `_nbsd.c` | NetBSD |
+| `_obsd.c` | OpenBSD |
+| `_sunos.c` | Solaris / illumos |
+| `_haiku.c` / `.cpp` | Haiku |
+| `_android.c` | Android (Termux) |
+| `_gnu.c` | GNU/Hurd |
+| `_nosupport.c` | Empty fallback |
+
+Current distribution of platform files in `detection/`:
+
+| Suffix | Files | Suffix | Files |
+|---|---|---|---|
+| `_linux` | 58 | `_obsd` | 16 |
+| `_windows` | 47 | `_haiku` | 13 |
+| `_apple` | 46 | `_android` | 12 |
+| `_nosupport` | 45 | `_gnu` | 3 |
+| `_bsd` | 29 | | |
+| `_sunos` | 19 | | |
+| `_nbsd` | 17 | | |
+
+(These are repository inventory figures, counting `.c`, `.m`, `.cpp`, and `.h`; they may change as platforms and modules are added.)
+
+**Do not accumulate `#ifdef __linux__` blocks in a single file.** When adding platform support, copy the closest existing implementation and change the suffix.
+
+`common/` follows the same convention: `common/impl/` contains `io_unix.c` / `io_windows.c`, `netif_linux.c` / `netif_apple.c` / `netif_bsd.c` and similar files, with `common/apple/`, `common/windows/` and `common/haiku/` holding platform-specific helpers.
+
+When several platform suffixes could apply, use the most specific implementation supported by the build system (for example, `_nbsd.c` instead of the generic `_bsd.c` on NetBSD). Keep the generic file as the fallback for platforms that share its conventions.
+
+---
+
+## Code style
+
+### Formatting
+
+The project uses clang-format with `BasedOnStyle: LLVM` plus these key overrides:
+
+```yaml
+IndentWidth: 4
+UseTab: Never
+ColumnLimit: 0              # never wrap
+InsertBraces: true          # braces even on single-statement ifs
+PointerAlignment: Left      # char* p, not char *p
+SortIncludes: Never         # include order is managed by hand
+AlignAfterOpenBracket: DontAlign
+BinPackParameters: false    # all params on one line, or one per line
+```
+
+Before committing:
+
+```sh
+clang-format -i src/modules/foo/*.c src/modules/foo/*.h
+```
+
+`src/3rdparty/**`, `build/**` and `src/logo/builtin.c` are listed in `.clang-format-ignore` — **do not reformat them.**
+
+`.editorconfig` specifies LF line endings, a 4-space indent, a final newline, and trailing whitespace trimmed (except in Markdown).
+
+### Naming
+
+| Kind | Convention | Example |
+|---|---|---|
+| Functions | `ff` + PascalCase | `ffDetectCPU`, `ffPrintCPU` |
+| Types | `FF` + PascalCase | `FFCPUResult`, `FFModuleBaseInfo` |
+| Variables / fields | camelCase | `coresPhysical`, `keyWidth` |
+| Macros | SCREAMING_SNAKE_CASE | `FF_OPTION_MAX_SIZE` |
+| Module options | `FF<Name>Options` | `FFCPUOptions` |
+| Detection results | `FF<Name>Result` | `FFCPUResult` |
+
+### Compiler warnings
+
+The build enables `-Wall -Wextra -Wconversion` plus several `-Werror`s:
+
+```
+-Werror=uninitialized -Werror=return-type -Werror=vla
+-Werror=incompatible-pointer-types -Werror=implicit-function-declaration -Werror=int-conversion
+```
+
+**`-Wconversion` is strict**: every implicit narrowing conversion needs an explicit cast.
+

+
+## Commit messages
+
+Format:
+
+```
+<Scope>[ (Platform)]: <third-person singular verb> <object>
+```
+
+Scope is the module or subsystem name; Platform is optional. Use the third-person singular present tense, capitalize the first letter, no trailing period.
+
+Real examples from recent history:
+
+```
+Processes (Haiku): honors `options->countKprocs`
+WM (macOS): improves reliability of WM plugin detection
+Memory (Windows): prefers `NQSI`
+Top (Linux): improves performance of `stat` parsing
+Logo (Builtin): adds omarchy
+Global: introduces global macro `FF_PATH_PKG_BASE` to replace `_PATH_LOCALBASE`
+LM (OpenBSD): adds support

+## Tests
+
+Tests are standalone executables in `tests/` using a `VERIFY` macro that exits non-zero on failure:
+
+```c
+#define VERIFY(expression) \
+    if (!(expression)) testFailed(&strbuf, #expression, __LINE__)
+```
+
+Current tests: `strbuf.c`, `list.c`, `format.c`, `color.c`, `duration.c`, `strutil.c`.
+
+```sh
+cmake -B build -DBUILD_TESTS=On
+cmake --build build
+cd build && ctest --output-on-failure
+```
+
+Coverage focuses on the core data structures and the formatting engine in `common/`. The `detection/` layer has no automated tests, because it depends on the state of a running system; it is instead covered by the CI matrix — 20 workflows under `.github/workflows/` spanning Linux (including musl, loong64, armv7l, i686), Android, macOS, Windows, FreeBSD, NetBSD, OpenBSD, DragonFly, Solaris, OmniOS and Haiku, plus a benchmark job. The Android job is the one that does not run what it builds: it cross-compiles for arm64-v8a, armeabi-v7a and x86_64 with the NDK at API 24 and inspects the result instead, because CI has no device or emulator. Its dynamic-symbol checks are what keep the weak references the platform branch depends on from turning into load failures on older devices.
+
+**If you modify `common/FFstrbuf.h`, `common/format.h` or `common/color.h`, extend the corresponding test.**

+## Pull requests
+
+1. **Open an issue first** (feature request / bug report / logo request) to confirm that the change is wanted before investing effort. Templates are in `.github/ISSUE_TEMPLATE/`.
+2. Branch off `dev` — **`dev` is the main development branch**, not `master`.
+3. Follow the [commit message convention](#commit-messages).
+4. Update `CHANGELOG.md` for user-visible changes.
+5. Open the PR against `dev` and fill in `.github/pull_request_template.md`:
+   - Summary
+   - Related issue (**required for new logos**; otherwise the PR is not accepted)
+   - Changes
+   - Screenshots (required for visual changes)

+./build/fastfetch -c presets/all.jsonc --stat false   # smoke-test every module
+```
+
+---
+
+## Pitfalls
+
+The following points are easy to misinterpret when reading this codebase. Most of them follow from the startup-time objective described above.
+
+### 1. Option structs must not exceed 256 bytes
+
+`FF_OPTION_MAX_SIZE = 1 << 8`. Exceeding it is caught at compile time by `static_assert`. Do not attempt to increase the value: it determines the stack cost of every module invocation.
+
+### 2. `FF_MODULE_DISABLE_*` controls registration, not compilation
+
+```c
+// verbatim from the top of modules/modules.c:
+// FF_MODULE_DISABLE_<module> only controls if the module is registered,
+// the module code itself is still compiled.
+// We rely `LTO` to remove the unused code (only enabled in Release mode)
+```
+
+**Disabling modules in a Debug build does not shrink the binary.** LTO is enabled whenever `CMAKE_BUILD_TYPE != Debug`, and the default `RelWithDebInfo` already satisfies that — so measure size with `RelWithDebInfo` or `Release`, never with `Debug`. (The "Release mode" wording in the comment above is imprecise.)
+
+### 3. Only two things are discovered by glob
+
+The module sources (`CMakeLists.txt:134`) and the logo `.txt` files (`CMakeLists.txt:429`). Both use `CONFIGURE_DEPENDS`, so with the Makefile and Ninja generators the build re-checks the glob and re-runs CMake when the result changes; other generators (Visual Studio and Xcode in particular) do not track it as reliably. Re-run `cmake -B build` after adding a module source or a logo file rather than relying on that behavior.
+
+Everything else — `src/detection/**` and `src/common/impl/**`, and any source outside the platform chain — must be listed in `CMakeLists.txt` by hand; see [step 5](#5-add-the-platform-sources-to-cmakeliststxt).
+
+### 4. CLI module options are removed
+
+Per-module command-line flags such as `--cpu-temp` are **no longer supported**. The only job of `ffParseModuleOptions` now is to translate the flag into a JSON key, then `exit(477)` with a pointer to the config file:
+
+```
+Error: Unsupported module option: --cpu-temp
+       Support of module options has been removed. Please add the flag to the JSON config instead.
+       Example (demonstration only): `{ "modules": [ { "type": "cpu", "temp": true } ] }`
+```
+
+**JSONC is the first-class configuration interface; the command line is not.** When adding module options, implement `parseJsonObject` only — do not add a CLI branch.
+
+### 5. `defaultOrder = 0` hides a module from `--gen-config`
+
+`collectModuleInfos` (`genconfig.c:186`) skips any module whose `defaultOrder` is `0`. C zero-initializes the field, so **omitting it is the same as setting it to 0**. Only `logo`, `command` and `custom` rely on this intentionally.
+
+`defaultOrder` affects only the ordering in the interactive `--gen-config` picker; it has no effect on the runtime output order.
+
+### 6. Localization uses byte offsets, not enums
+
+`instance.config.display.keyLanguage` does not hold a language enum — it holds a **byte offset** such as `offsetof(FFModuleDisplayName, zh_CN)`. The macro `FF_MODULE_GET_DISPLAY_NAME` (`common/option.h:123`) does plain pointer arithmetic with it:
+
+```c
+#define FF_MODULE_GET_DISPLAY_NAME(moduleName) \
+    (*(const char**) ((uint8_t*) &ff ## moduleName ## ModuleInfo.displayName + instance.config.display.keyLanguage))
+```
+
+Consequence: **the field order of `FFModuleDisplayName` must never change** — reordering the fields silently corrupts the output for every language.
+
+### 7. The `multithreading` option has limited effect
+
+The global `multithreading` option currently takes effect in exactly one place: `common/impl/networking_linux.c:339`. Modules are still printed sequentially. Modules that need concurrency go through the `ffPrepare*` warm-up hooks instead, which start sampling or fire off requests before the print loop begins.
+
+This may change in the future. The main blocking issue is that there are dependencies between different modules.
+
+### 8. Do not print or read configuration inside `detection/`
+
+The `detection/` layer must stay pure: read system state, fill a struct, return an error string. Any `printf` or any read of `instance.config` there is a design error.
+
+Use `FF_DEBUG` (`src/common/debug.h`) for logging.
+
+### 9. `src/logo/builtin.c` and `3rdparty/` are formatting-exempt
+
+The former is a large generated and hand-maintained data table; the latter is upstream code. Both are excluded via `.clang-format-ignore`; do not reformat either.

+# libsixel (encoder subset, vendored)
+
+Encoder-only subset of [libsixel](https://github.com/saitoha/libsixel) `1.8.7-r2`,
+used by `src/logo/image/` to render the `sixel` logo type **on Windows and macOS**.
+
+## Why this is vendored
+
+Neither MSYS2 nor vcpkg packages libsixel, so on Windows there is nothing to
+`dlopen()` or to link against. The encoder is small and has no external
+dependencies, so the necessary files are embedded instead. The intent is to upstream
+a libsixel package to MSYS2 later and switch to it; until then this directory is the
+source of truth.
+
+macOS *does* have a package — Homebrew's `libsixel` is this very version, `1.8.7-r2`
+(`brew info libsixel`) — but it is deliberately not used. It drags in `jpeg-turbo` /
+`libpng` for the decoder side we never call, and linking it would mean a different
+encoder on each platform. Since Windows needs an embedded copy regardless, one shared
+copy is simpler than two.
+
+## Why only Windows and macOS
+
+Windows loses ImageMagick entirely — its image backend moves to WIC, which decodes
+and scales but cannot *encode* sixel — so it needs an encoder of its own.
+
+macOS does not get ImageMagick either: `ENABLE_IMAGEMAGICK6` / `ENABLE_IMAGEMAGICK7`
+are gated on `LINUX OR FreeBSD OR OpenBSD OR NetBSD OR ANDROID OR SunOS OR Haiku OR
+GNU`, with no `APPLE`, and its image backend is ImageIO. So it shares the same
+requirement.
+
+On every other platform ImageMagick stays, and it already produces sixel through
+its own SIXEL coder. Adding libsixel there would mean a second encoder for a
+capability that already works: one more dependency for zero gain. So `ENABLE_SIXEL`
+is gated on `WIN32 OR APPLE`, and these sources are **not compiled at all** on
+Linux / the BSDs.
+
+Consequence: sixel bytes differ between Windows / macOS (libsixel) and the rest
+(ImageMagick). That is deliberate and accepted — see
+`doc/windows-image-backend.md` decision 9.
+
+## Transparency
+
+The subset is used for its keycolor support. `sixel_dither_set_transparent()` marks a
+palette index as the transparent one; `output_rgb_palette_definition()` then leaves that
+entry out of the palette definition, and `sixel_encode_body()` never puts a keycolor
+pixel into the node map, so nothing is drawn there and the terminal background shows
+through. `src/logo/image/sixel.c` drives this for sources that contain fully transparent
+pixels — it maps those pixels onto a dedicated index one past the quantized palette,
+because keying a *content* colour would also drop every opaque pixel that shares it.
+
+Two things have to line up for the background to actually be transparent: the caller has to
+mark a keycolor, so the keyed pixels are never painted (above), **and** the encoder has to ask
+for a transparent background, so the terminal leaves those unpainted pixels alone instead of
+filling them. The second half is the DCS `P2` parameter — see
+[Local modifications](#local-modifications) item 3.
+
+Note what this is and is not: it is a **palette-index** keycolor, not alpha support. A
+partially transparent pixel has to be drawn in its unblended colour, since a sixel has
+no way to blend with whatever the terminal has behind it.
+
+⚠️ Do not vendor a *newer* libsixel in the belief that this version cannot do
+transparency. It can, and it was measured: the official `1.8.7-r2` omits the keycolor
+entry and leaves the keyed pixels unpainted, with the remaining pixels correctly placed.
+When a transparent background is not showing up, check the caller first — historically
+the caller simply never called `sixel_dither_set_transparent()`, and an image logo only
+renders correctly once it does. If the caller *is* setting a keycolor and the background is
+still solid, check `P2` instead: the keyed pixels are being left unpainted correctly, but the
+terminal is filling them.
+
+## What was kept
+
+Starting from `sixel_dither_new` / `sixel_dither_initialize` / `sixel_output_new` /
+`sixel_encode` and following the dependency closure, only these files are reachable:
+
+| File | Provides |
+|---|---|
+| `tosixel.c` | `sixel_encode`, `sixel_putc`, `sixel_node_*`, DCS envelope handling |
+| `dither.c` / `dither.h` | `sixel_dither_new`, `sixel_dither_initialize`, `sixel_dither_unref` |
+| `output.c` / `output.h` | `sixel_output_new`, `sixel_output_unref` |
+| `quant.c` / `quant.h` | Median-cut palette construction |
+| `pixelformat.c` | `sixel_helper_compute_depth`, `sixel_helper_normalize_pixelformat` |
+| `allocator.c` / `allocator.h` | `sixel_allocator_*` |
+| `status.c` / `status.h` | `sixel_helper_set_additional_message` |
+| `malloc_stub.h` | Included by `allocator.c`; compiles to nothing when `HAVE_MALLOC` |
+| `sixel.h` | Public API (upstream `include/sixel.h`) |
+
+## What was removed
+
+Everything else in the upstream tree, in particular:
+
+- **Decoding**: `decoder.c`, `fromsixel.c`, `frompnm.c`, `fromgif.c`, `frame.c`,
+  `loader.c`, `stb_image.h`, `stb_image_write.*`. Image decoding is done by the
+  platform backend (WIC on Windows, ImageIO on macOS, ImageMagick elsewhere), so
+  libsixel only ever sees an RGBA8 buffer here.
+- **The `sixel_encoder_*` / `sixel_decoder_*` high-level API**: `encoder.c`,
+  `writer.c`, `tty.c`, `scale.c`. These pull in file I/O, terminal probing and the
+  loader registry. We call the dither/output/encode trio directly.
+- **`rgblookup.h` / `rgblookup.gperf`**: a gperf-generated color-name table used
+  only by `encoder.c` for `--builtin-palette` parsing.
+- **`converters/`** (`img2sixel`, `sixel2png`), **`python/`**, **`tools/`**,
+  **`tests/`**, **`images/`** (216 test images), and the packaging templates
+  (`package.json.in.in`, `libsixel.pc.in`).
+- **The autotools machinery**: `configure`, `Makefile.in`, `aclocal.m4`, `m4/`,
+  `ltmain.sh`, `config.h.in`, … See item 2 under
+  [Local modifications](#local-modifications).
+- **Six of the nine `LICENSE.*` files**: `LICENSE.images` / `.mesa` / `.pngsuite` /
+  `.sdump` / `.stb` cover only material that was dropped (test images, the OpenGL
+  example, the `sdump` tool, stb). The three that remain are the complete set
+  required by the files above — verified against each file's own header, see
+  [License](#license).
+
+Result: **20 files / 256 KB**, down from 319 files / 11.3 MB. Note that 8.0 MB of
+that 11.3 MB was `images/` fixtures, so the meaningful comparison is code:
+`src/` + `include/` went from 50 files / 1.17 MB to 20 files / 256 KB.
+
+## Local modifications
+
+Four deliberate divergences from upstream. Re-apply all four when re-syncing.
+
+1. **`sixel.h` — `SIXELAPI` is empty.** Upstream defines it as
+   `__declspec(dllexport)` on Windows. This subset is compiled into `libfastfetch`
+   statically rather than into a standalone DLL, so the attribute would (a) add
+   every libsixel symbol to fastfetch's export table and (b) make `sixel.h`'s
+   declarations disagree with the ones in `dither.h` / `output.h` / `quant.h` /
+   `allocator.h`, which do not carry it (clang warns:
+   `-Wdll-attribute-on-redeclaration`).
+
+2. **`config.h` is hand-written.** Upstream generates it with `configure`. Only
+   these vendored files read it, and they reference a small fixed set of macros,
+   so the values are hard-coded. Two things to watch:
+   - `HAVE_TESTS` must stay **undefined**, not `0`: `sixel.h` gates its test-only
+     declarations with `#ifdef HAVE_TESTS`, so `#define HAVE_TESTS 0` would still
+     pull in declarations for functions we do not compile.
+   - `HAVE_MEMORY_H` / `HAVE_STRING_H` must be `1`. fastfetch builds with
+     `-Werror=implicit-function-declaration`, so a missing `<memory.h>` /
+     `<string.h>` include in `pixelformat.c` / `status.c` is a hard error.
+
+3. **`tosixel.c` — the DCS `P2` parameter is initialised to 1.** `sixel_encode_header()`
+   declares `int p[3] = {0, 0, 0}`, and the trailing-zero trimming right below it then drops
+   all three, so the envelope is a bare `ESC P q`. That means `P2 = 0`, which tells the
+   terminal to fill every unset pixel with **colour-table entry 0** — and that entry is
+   defined by the image's own palette, so a keycolor image comes out with a solid rectangle
+   behind it rather than transparency. Setting `p[1] = 1` leaves unset pixels untouched.
+
+   The trimming still drops the trailing aspect-ratio parameter, so the envelope is
+   `ESC P 0;1 q`. `P3` defaults to 0 and the two spellings are equivalent — verified by
+   decoding both with libsixel's own decoder and with ImageMagick's. ImageMagick's SIXEL
+   coder and chafa both write `0;1;0` explicitly.
+
+   This only shows up on a terminal that implements the VT340 background rule. Windows
+   Terminal does (`_backgroundFillRequired = (_conformanceLevel == 1 || !transparent)` in
+   `src/terminal/adapter/SixelParser.cpp`), which is where it was reproduced; WezTerm does
+   not fill, so the identical bytes look correct there. It is also why Linux never showed
+   the problem: that path goes through ImageMagick, which already sends `P2 = 1`.
+
+4. **`output.c` — release the allocator reference if output allocation fails.**
+  `sixel_output_new()` creates an allocator or takes an additional reference before
+  allocating the output context. If that allocation fails, the reference is not owned by
+  an output object and must be released before returning `SIXEL_BAD_ALLOCATION`.
+  Fastfetch passes a null allocator, so without this cleanup the newly created allocator
+  becomes unreachable on this error path. The successful path and returned error code are
+  unchanged.
+
+The vendored sources are also exempted from `-Wconversion` in `CMakeLists.txt`:
+upstream has ~160 implicit int→`unsigned char` narrowing warnings. Everything else
+(`-Wall -Wextra` and fastfetch's `-Werror=` set) applies unchanged, and the subset
+compiles clean.
+
+## Re-syncing with upstream
+
+```sh
+VER=1.8.7-r2
+git clone --depth 1 --branch "$VER" https://github.com/saitoha/libsixel /tmp/libsixel
+
+# 1. copy the closure (paths change from src/foo.c to foo.c, include/sixel.h to sixel.h)
+for f in tosixel.c dither.c dither.h output.c output.h quant.c quant.h \
+         pixelformat.c allocator.c allocator.h status.c status.h malloc_stub.h; do
+    cp "/tmp/libsixel/src/$f" .
+done
+cp /tmp/libsixel/include/sixel.h .
+cp /tmp/libsixel/LICENSE /tmp/libsixel/LICENSE.sixel /tmp/libsixel/LICENSE.pnmcolormap .
+
+# 2. re-apply the four local modifications listed above
+# 3. verify
+```
+
+Verification (must be 0 diagnostics, and the encoder must emit a DCS-wrapped stream).
+Both platforms compile this subset, so run it on both:
+
+```sh
+# Windows: CC=/c/msys64/clang64/bin/cc.exe
+# macOS:   CC=cc   (verified with Apple clang 21: 0 diagnostics)
+CC=cc
+FLAGS="-I. -Wall -Wextra -Wconversion -Wno-conversion -Werror=uninitialized \
+ -Werror=return-type -Werror=vla -Werror=incompatible-pointer-types \
+ -Werror=implicit-function-declaration -Werror=int-conversion -std=gnu23"
+for f in tosixel dither output quant allocator pixelformat status; do
+    $CC $FLAGS -c $f.c -o /dev/null || echo "FAILED: $f"
+done
+```
+
+If upstream adds a call from the closure to a new file, the build fails at link
+time with an undefined `sixel_*` symbol — add that file and repeat.
+

+// ---------------------------------------------------------------------------------------------
+// Contract attributes used throughout this header:
+//
+// `gnu::pure` marks a function that reads memory (through its arguments and through globals) but
+// writes nothing observable, so the compiler may cache and reorder calls to it. It is applied to
+// the comparison / search accessors, and deliberately NOT to:
+//   * the `To*` converters -- `strtod` / `strtoull` / `strtoll` write `errno`;
+//   * `ffStrbufEndsWithFn` -- the caller-supplied `fn` may have side effects;
+//   * `ffStrbufWriteTo` / `ffStrbufPutTo` -- they write to a `FILE*`.
+//
+// `gnu::nonnull(N)` is added wherever the function dereferences argument N unconditionally. The
+// two cannot be combined with a null check: clang reports `-Wtautological-pointer-compare` /
+// `-Wpointer-bool-conversion` (both in `-Wall`) when a `nonnull` parameter is compared against
+// null, so a redundant `assert(p != nullptr)` is dropped in favour of the attribute. Asserts that
+// state something `nonnull` cannot express -- pointer aliasing (`value != strbuf`), index ranges
+// (`start <= strbuf->length`), or a non-pointer invariant -- are kept.
+//
+// `nodiscard` is NOT applied to the "was the buffer modified" boolean returns
+// (`ffStrbufSubstr*`, `ffStrbufRemoveSubstr`, `ffStrbufEnsureEndsWithC`, ...). Ignoring that
+// result is a normal, intended use of those functions -- `ffStrbufSubstrBefore` alone has 153 call
+// sites and ~147 of them discard the result -- so `nodiscard` would only produce noise.

+// NDK has no BatteryManager / WifiManager, libbinder_ndk only speaks to AIDL HALs (it refuses to
+// prepare a transaction for a binder that has no NDK class), and `/system/bin/service call` costs a
+// fork/exec worth 15-20 ms. What is left is /dev/binder itself, which is all that `service` uses
+// underneath. This header speaks that protocol directly: open() + mmap() + BINDER_WRITE_READ, no
+// extra shared library, no child process, ~0.13 ms per call once a handle is cached.
+//
+// Three details are easy to get wrong. All three were confirmed against the device's own
+// libbinder.so and with a ptrace trace of `service`, and getting any of them wrong makes the
+// service answer BAD_TYPE (0x80000001) or BR_FAILED_REPLY (0x7211):
+//
+//   * A request parcel must start with three int32 values -- strict mode policy, work source and
+//     'SYST'. Parcel::markForBinder() writes nothing for kernel binder, but the receiving side's
+//     Parcel::enforceInterface() still compares the third word against its own header.
+//   * Parcel::writeString16() writes the length, the UTF-16 code units, a UTF-16 NUL terminator and
+//     then pads to four bytes. Skipping the terminator shifts every following field by four bytes.
+//   * A handle arriving in a reply is owned by that reply buffer. It has to be acquired
+//     (BC_ACQUIRE + BC_INCREFS) before BC_FREE_BUFFER; otherwise only a weak reference survives and
+//     every later transaction on it fails, because the kernel looks up a strong reference.

+// dex stores a class's instance fields sorted by field index, which is sorted by *name*, so the
+// declaration order a reader would want is not recorded anywhere but the method body.
+//
+// Recovering it therefore means walking the bytecode. The compiler emits
+//
+//     iget v0, p0, LDisplayInfo;->logicalWidth:I
+//     invoke-virtual {p1, v0}, Landroid/os/Parcel;->writeInt(I)V
+//
+// once per field, in write order, so the `iget` opcodes in a linear pass over the instruction grid
+// are the sequence. Two things have to be got right for that pass to stay on the grid, and both are
+// easy to get wrong in a way that still produces a plausible-looking list:
+//
+//  * Instructions are 1, 2, 3, 4 or 5 code units wide, and the width is a property of the opcode.
+//    The table below is ART's `Instruction::SizeInCodeUnits`.
+//  * The payload pseudo-instructions a `switch` or a `fill-array-data` leaves in the stream have a
+//    low byte of zero and a high byte of 1, 2 or 3. They are not instructions, they sit behind every
+//    reachable instruction, and stepping into one desynchronises the grid -- so the walk stops at the
+//    first of them rather than trying to step over it.
+//
+// An array field is read twice: once for its `length`, which is the count that goes on the wire, and
+// again inside the loop that writes the elements. A class cannot declare two instance fields under
+// one name, so a repeat is always that reload, and the first occurrence is where the field is
+// written. The reader de-duplicates by name for that reason.
+//
+// What is *not* recovered is how each field is framed -- `writeString` against `writeString8`,
+// `writeParcelable` against `writeTypedObject`. That is a property of the method the field is handed
+// to, not of the field, and two `String` fields of the same class can differ: `DisplayInfo.name` goes
+// through `writeString8` while `DeviceProductInfo.mName` goes through `writeString`. Telling them
+// apart would mean resolving every invoke target, so the type descriptor is reported instead and the
+// caller frames the fields its descriptor settles -- an `I`, a `J`, an `[F` -- and names the few it
+// does not. Measured over three releases' own `framework.jar`, that is four names per class.
+//
+// The point of asking the device rather than carrying a table is that the field set moves: `DisplayInfo`
+// has 34 instance fields on Android 11, 42 on 13 and 59 on 16, and the fields that arrived in between
+// (`displayGroupId`, `renderFrameRate`, `appsSupportedModes`, `committedState`, ...) are exactly the

+// Locating an entry inside a zip, which is what both the jar reader and the app label reader need:
+// one looks for `classesN.dex`, the other for the resource table of an APK.
+//
+// The entry is found through the central directory rather than by scanning for its local header,
+// and that is not a micro-optimisation. A local header is preceded by everything that came before
+// it, so scanning costs a pass over all of it, once per lookup: `framework.jar` is 52 MB and its

+// seven codes, looking the entries up by scanning was the difference between 30 ms and 2 seconds.
+//
+// The sizes and the compression method are read from the directory rather than from the entry's own
+// local header, which is the more reliable of the two: a local header is allowed to leave its sizes
+// at zero and put them in a data descriptor behind the payload, and an archive writer is free to
