# setup-bazel
This action allows to properly configure Bazelisk and Bazel on all operating systems
and provides an advanced fine-grained caching to improve workflows performance.
## Inputs
### `bazelisk-cache`
Cache [`bazelisk`][1] downloads based on contents of a `.bazelversion` file.
Default `false`.
### `bazelisk-version`
[`bazelisk`][1] version to download and use.
Supports semver specification and ranges.
Leave empty to use [pre-installed Bazelisk][8].
Default `""`.
### `bazelrc`
Extra contents to write to a user's [`bazelrc`][4] file.
Default `""`.
### `disk-cache`
Enable [`disk_cache`][2] and store it on GitHub based on contents of `BUILD` files.
You can also pass a string to use as a cache key to separate caches from different workflows.
Default `false`.
### `external-cache`
Cache `external/` repositories based on contents of a `WORKSPACE` file.
Only repositories exceeding 10MB are being cached.
You can also pass a YAML object where key is the name of the external repository
and value is the list of files which contents are used to calculate cache key.
Default `false`.
### `repository-cache`
Enable [`repository_cache`][3] and store it on GitHub based on contents of a `WORKSPACE` file.
Default `false`.
## Examples
### Simple configuration
```yaml
- uses: p0deje/setup-bazel@0.6.0
```
### Custom Bazelisk version
```yaml
- uses: p0deje/setup-bazel@0.6.0
with:
bazelisk-version: 1.19.0
```
### Additional `.bazelrc` options
```yaml
- uses: p0deje/setup-bazel@0.6.0
with:
bazelrc: |
build --show_timestamps
```
### Full caching enabled
```yaml
- uses: p0deje/setup-bazel@0.6.0
with:
bazelisk-cache: true
disk-cache: true
external-cache: true
repository-cache: true
```
### Separate disk cache between workflows
```yaml
- uses: p0deje/setup-bazel@0.6.0
with:
disk-cache: ${{ github.workflow }}}
```
### Cache external repository based on different files
```yaml
- uses: p0deje/setup-bazel@0.6.0
with:
external-cache: |
manifest:
npm: package-lock.json
```
### Disable individual external repositories conditionally
```yaml
- uses: p0deje/setup-bazel@0.6.0
with:
external-cache: |
manifest:
ruby: ${{ matrix.os == 'windows' && 'false' || '.ruby-version' }}
```
## Migrating from [`bazelbuild/setup-bazelisk`][6]
You can simply replace `bazelbuild/setup-bazelisk` action with `p0deje/setup-bazel`.
However, if you used a `bazel-version` input before, you will need to remove it in favor
[other ways to specify Bazel version][7].
