## Historique du projet et usages

usage is both a specification and a CLI for describing command-line interfaces. The official README compares a Usage spec to OpenAPI for CLIs, covering arguments, flags, environment variables, and config files so downstream tools can generate completions, documentation, man pages, parsers, SDKs, and framework scaffolding.

### Historique du projet

The project grew out of the modern CLI tooling ecosystem around jdx's tools and the KDL document language. Public GitHub releases show early v0.1.x releases in 2024 and v3.x releases in 2026, while the docs describe an expanding scope from shell completions and man pages toward type-safe SDK generation.

### Historique d'adoption

The official CLI docs list installation through mise, Cargo, Homebrew, and Arch Linux. The input metadata also records Homebrew, Nix, and pacman package names, indicating adoption by users who want the same CLI-spec tool available across developer workstations and Linux distributions.

### Modes d'utilisation

A Usage spec is written in KDL and can describe a CLI's name, binary, about text, version, author, license, flags, arguments, subcommands, config files, environment variables, and defaults. The `usage` CLI then consumes that spec to generate shell completions, Markdown, man pages, JSON, and related artifacts.

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

Package nerds care about usage because it treats CLI metadata as a portable build artifact. Instead of each package separately hand-maintaining completions, man pages, and docs, maintainers can ship a spec and generate those outputs consistently.

### Chronologie

- 2024: Early v0.1.x GitHub releases published.
- 2026-06-23: GitHub release v3.5.3 published.

### Related projects

- The official docs relate Usage to OpenAPI for CLIs, KDL as the spec language, and integrations for CLI frameworks such as clap, Cobra, Click, Typer, yargs, oclif, and Commander.js.
