## Historique du projet et usages

hellwal is a small color-palette generator for wallpaper-driven desktop theming. Its repository describes it as a Pywal-like generator that is faster and written in C, with templates, themes, JSON output, light and dark modes, and terminal color helpers.

The available authoritative history is thin but useful: the GitHub repository and release notes show a young project that quickly accumulated practical theming features after its first public release.

### Historique du projet

The repository was created in November 2024. The first public release, v1.0.0, described hellwal as a pywal-inspired color palette generator with support for templates, themes, and command-line arguments.

Subsequent releases added cache support, JSON output, neon mode, preview flags, contrast checking, more templates, and fixes to parser and palette behavior. The README credits pywal as the inspiration.

### Historique d'adoption

The project crossed from source builds into package-manager use early in its life. The README documents Homebrew and Nix installation, and the supplied package metadata also lists Homebrew and Nix packaging.

Its audience is the Unix desktop theming and 'rice' community: users who want one image or theme file to drive terminal, launcher, compositor, notification, editor, and shell color files.

### Modes d'utilisation

Users run `hellwal -i [image]` to generate a palette from a wallpaper image, or use `--theme` to apply a static palette. Generated templates are written under the user's cache directory, and theme files can live under `~/.config/hellwal/themes`.

The tool can emit JSON for scripts, write terminal color scripts, run a post-generation command, choose light or dark modes, adjust brightness and grayscale, and fill template variables such as `color0.hex`, `background.rgb`, and alpha values.

### Pourquoi les passionnés de paquets s'y intéressent

hellwal is notable as a compact C entry in a space often occupied by Python scripts. That makes it attractive to packagers who want a fast, dependency-light theming utility with predictable build behavior.

It is also a good example of desktop theming tools becoming package-manager artifacts: templates, cache paths, shell completions, and example themes matter almost as much as the binary.

### Chronologie

- 2024: Public GitHub repository created.
- 2024: v1.0.0 release published with templates, themes, and command-line options.
- 2024: v1.0.2 added palette caching under the user cache directory.
