Reusable Gitea Actions for CI workflows.

Actions

nix-setup

Installs Nix and sets up Nix store caching for Gitea Actions workflows.

Features:

Uses DeterminateSystems/nix-installer-action for reliable Nix installation
Caches /nix/store, /nix/var/nix, and ~/.cache/nix
Cache key based on flake.lock hash for automatic invalidation
Each repo gets isolated cache (different flake.lock = different cache)

Usage:

  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: johno/gitea-actions/nix-setup@main
      - run: nix flake check

With custom cache prefix:

- uses: johno/gitea-actions/nix-setup@main
  with:
    cache-name: 'my-project-'

Inputs:

Input	Description	Required	Default
`cache-name`	Optional cache name prefix for disambiguation	No	`''`
