Cache Action
============
A Gitea Action that caches build files under `~/.cache/` using a key file hash. This action uses `actions/cache@v5` under the hood and automatically saves the cache when the job completes successfully.
## Inputs
| Input | Description | Required | Default |
|-------|-------------|----------|---------|
| `path` | Files/directories to cache | No | `~/.cache/` |
| `key` | Explicit cache key | No | Auto-generated from hash |
| `key-file` | File to hash for cache key generation | No | Auto-detects lockfiles |
| `restore-keys` | Fallback prefix-matched keys | No | `{os}-cache-` |
## Outputs
| Output | Description |
|--------|-------------|
| `cache-hit` | `true` if exact key match found, `false` otherwise |
## Quick Start
### Basic Usage
```yaml
name: Build with Cache
on: push
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: Actions/Cache@main
- run: echo "Cache restored, proceeding with build..."
```
### Rust Example
```yaml
name: Rust Build
on: push
defaults:
run:
shell: bash
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: Actions/Cache@main
with:
key-file: 'Cargo.lock'
path: |
~/.cache/
~/.cargo/registry
~/.cargo/git
target
- name: Build
run: |
cargo build --release
```
### Skip Steps on Cache Hit
```yaml
name: Build with Conditional Steps
on: push
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: Actions/Cache@main
id: cache
with:
key-file: 'Cargo.lock'
- name: Install dependencies
if: steps.cache.outputs.cache-hit != 'true'
run: cargo fetch
- name: Build
run: cargo build --release
```
## How It Works
1. **Cache Key Generation**: If no explicit `key` is provided, the action auto-generates one by:
- Hashing the specified `key-file` if provided
- Otherwise, hashing all detected lockfiles (package-lock.json, Cargo.lock, go.mod, etc.)
- Falls back to hashing all non-git files if no lockfiles found
2. **Cache Restore**: Uses `actions/cache@v5` to restore the cache from `~/.cache/`
3. **Cache Save**: Automatically saves the cache when the job completes successfully (handled by `actions/cache@v5`)
## Cache Scope
The cache is scoped to the key, version, and branch. The default branch cache is available to other branches.
## Remarks
- Requires Gitea Actions runner version >= 2.327.1 for `actions/cache@v5`
- The cache server must be enabled on your Gitea instance
- Maximum cache size per repository is 10GB
