+# 2.68.0
+
+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.
+* 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.
+
+Logos:
+* Added macOS_old
+* Added Omarchy, Omarchy2
+
+# 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)

+
+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:
+* Added Flatcar, Azure Linux
+* Added Chimera_small, Chimera2, Parabola2_small, PostmarketOS2, Qubes_small

+* Cleaned up distro names
+
+# 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
+
+Bugfixes:
+* 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)

+Thanks 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 is borderline obsessive about **startup time** and **optional dependencies** — many design decisions only make sense under that constraint, and this document keeps coming back to it.

+## 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` | `cmake -B build && cmake --build build -j` |
+| Add a platform implementation | `src/detection/<name>/<name>_<platform>.c` | 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 normal code change, the shortest useful loop 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 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 already has it, and only `Debug` builds lack it. This matters because LTO here is not merely an optimization: it is what strips the code of disabled modules. See [Gotchas](#gotchas).
+
+### 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, pulse, ddcutil, elf, libzfs, and more.

+```
+
+Flow of control:
+
+```
+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 and detection directories does not match, and that 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 someone else'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`.
+
+So do not assume `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 |
+
+The test is simple: **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 single most important convention in the codebase. Every feature is 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 — usually just two things:
+
+```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 payoff:** 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 openly admits this is UB — `void*` is not compatible with `FF*Options*`. It is a pragmatic compromise to get polymorphism in C. Don't try 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)) { ... }
+}
+```
+
+The registry is small enough that a subtraction plus 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`; 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");
+```
+
+**Meaning: no module option struct may exceed 256 bytes.** 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 |
+| `ffParseModuleOptions` | `common/impl/commandoption.c:13` | **deprecated** — see [Gotchas](#4-cli-module-options-are-removed) |
+
+### Build-time module discovery
+
+`CMakeLists.txt:131` globs `src/modules/*/` and generates a `MODULE_DISABLE_<UPPER>` option per directory:
+
+```cmake
+file(GLOB FF_MODULE_DIRS RELATIVE "..." ".../src/modules/*/")
+foreach(FF_MODULE_DIR ${FF_MODULE_DIRS})
+    option(MODULE_DISABLE_${FF_MODULE_UPPER} "Disable module ${FF_MODULE_DIR}" OFF)
+endforeach()
+```
+
+**Adding a module requires no CMake change.** The same trick generates the package manager switches (`:146` regex-scans `src/modules/packages/option.h` for `FF_PACKAGES_FLAG_*_BIT`).
+
+---
+
+## 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()` can handle these generically and you get them **for free — no parsing code to write**.
+
+Note these fields can only be set through the JSON config; CLI module options have been removed (see [Gotchas](#4-cli-module-options-are-removed)).
+
+### 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, and a `foo_nosupport.c` fallback for the rest.** There are already 45 `*_nosupport.c` files doing exactly this.
+
+### 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 a neighboring 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 [Gotchas](#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`; **anything you omit is invisible and unusable to 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`, makes the module **disappear** from the interactive `--gen-config` picker. Only `logo`, `command` and `custom` do this deliberately, because they need 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. 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 right first-letter `case`. Six modules do this today: CPUUsage, DiskIO, NetIO, PublicIP, Top and Weather.
+
+### 6. 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` does not work, only `fastfetch -h foo-format`.
+
+---
+
+## 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. Drop in the ASCII file
+
+```
+src/logo/ascii/<first-letter>/<distro>.txt
+```
+
+For example `src/logo/ascii/o/omarchy.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 (`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**; 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` 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
+#ifdef FASTFETCH_DATATEXT_LOGO_OMARCHY
+// Omarchy
+{
+    .names = { "omarchy", "Omarchy" },
+    .lines = FASTFETCH_DATATEXT_LOGO_OMARCHY,
+    .colors = {
+        FF_COLOR_FG_BLUE,
+        FF_COLOR_FG_WHITE,
+        FF_COLOR_FG_CYAN,
+    },
+},
+#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 `--logo <source>`.
+
+### 3. Verify
+
+```sh
+./build/fastfetch --logo omarchy
+./build/fastfetch --list-logos | grep -i omarchy
+```
+
+---
+
+## 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.)
+
+**Don't pile `#ifdef __linux__` into one file.** When adding platform support, copy the closest existing implementation and change the suffix.
+
+`common/` uses the same idea: `common/impl/` contains `io_unix.c` / `io_windows.c`, `netif_linux.c` / `netif_apple.c` / `netif_bsd.c` and so on, 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` adds LF line endings, 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` |
+
+### Spelling
+
+CI runs codespell (`.codespellrc`). Known false positives live in `ignore-words-list` (`iterm`, `compiletime`, and various non-English distro words). Add new words there rather than changing the code.
+
+### 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
+CI: disables fail on alert
+Doc: updates README
+Presets: moves `top` to the bottom of running modules [ci skip]
+```
+
+Common verbs: `adds`, `removes`, `fixes`, `improves`, `updates`, `corrects`, `prefers`, `honors`, `disables`, `enables`, `introduces`, `detects`, `reports`, `skips`, `uses`.
+
+Scopes in use: `Top`, `Processes`, `Memory`, `Logo (Builtin)`, `CI`, `Doc`, `Presets`, `Global`, plus individual module names.
+
+Documentation-only changes get a `[ci skip]` suffix.

+## 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 (it depends too heavily on a real system) and is instead covered by the CI matrix — 20 workflows under `.github/workflows/` spanning Linux (including musl, loong64, armv7l, i686), macOS, Windows, FreeBSD, NetBSD, OpenBSD, DragonFly, Solaris, OmniOS and Haiku, plus spellcheck and benchmark jobs.
+
+**If you touch `common/FFstrbuf.h`, `common/format.h` or `common/color.h`, please extend the matching test.**
+

+
+## Pull requests
+
+1. **Open an issue first** (feature request / bug report / logo request) so you don't waste effort. Templates are in `.github/ISSUE_TEMPLATE/`.

+

+
+## Gotchas
+
+Things that are easy to get wrong when reading this codebase. Most of them follow from the "obsessively fast startup" goal.
+
+### 1. Option structs must not exceed 256 bytes
+
+`FF_OPTION_MAX_SIZE = 1 << 8`. Exceeding it is caught at compile time by `static_assert`. Don't try to raise 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. CMake globs don't trigger reconfiguration
+
+Both the module directories and the logo files are discovered by glob. CMake will not notice new files on its own — you need to re-run `cmake -B build` (or delete `build/CMakeCache.txt` and start over). This is the classic CMake footgun.
+
+### 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` do this on purpose.
+
+`defaultOrder` affects only the ordering in the interactive `--gen-config` picker; it has no effect on 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 silently scrambles every language.
+
+### 7. The `multithreading` switch barely does anything
+
+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.
+
+### 8. Don't print or read config 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.
+
+### 9. `src/logo/builtin.c` and `3rdparty/` are formatting-exempt
+
+The former is a large generated/hand-maintained data table, the latter is upstream code. Both are excluded via `.clang-format-ignore` — leave them alone.

 ### Q: Fastfetch shows fewer dpkg packages than neofetch. Is it a bug?
 
-Neofetch incorrectly counts `rc` packages (packages that have been removed but still have configuration files remaining). See bug: https://github.com/dylanaraps/neofetch/issues/2278
+1. Neofetch incorrectly counts `rc` packages for apt (packages that have been removed but still have configuration files remaining). See bug: https://github.com/dylanaraps/neofetch/issues/2278
+2. Neofetch incorrectly counts `gpg-pubkey` as packages for rpm. You may check the results of `dnf list --installed | wc -l` and `rpm -qa | wc -l` to see the difference.
 
 ### Q: I use Debian / Ubuntu / Debian-derived distro. My GPU is detected as `XXXX Device XXXX (VGA compatible)`. Is this a bug?
