This action sets up a go environment for use in actions by:
|
|
|
|
- optionally downloading and caching a version of Go by version and adding to PATH
|
|
- registering problem matchers for error output
|
|
|
|
# V3
|
|
|
|
The V3 offers:
|
|
- Adds GOBIN to the PATH
|
|
- Proxy Support
|
|
- `stable` input
|
|
- Check latest version
|
|
- Bug Fixes (including issues around version matching and semver)
|
|
|
|
The action will first check the local cache for a version match. If a version is not found locally, it will pull it from the `main` branch of the [go-versions](https://github.com/actions/go-versions/blob/main/versions-manifest.json) repository. On miss or failure, it will fall back to downloading directly from [go dist](https://storage.googleapis.com/golang). To change the default behavior, please use the [check-latest input](#check-latest-version).
|
|
|
|
Matching by [semver spec](https://github.com/npm/node-semver):
|
|
```yaml
|
|
steps:
|
|
- uses: actions/checkout@v2
|
|
- uses: actions/setup-go@v3
|
|
with:
|
|
go-version: '^1.13.1' # The Go version to download (if necessary) and use.
|
|
- run: go version
|
|
```
|
|
|
|
Matching an unstable pre-release:
|
|
```yaml
|
|
steps:
|
|
- uses: actions/checkout@v2
|
|
- uses: actions/setup-go@v3
|
|
with:
|
|
stable: 'false'
|
|
go-version: '1.14.0-rc1' # The Go version to download (if necessary) and use.
|
|
- run: go version
|
|
```
|
|
|
|
# Usage
|
|
|
|
See [action.yml](action.yml)
|
|
|
|
## Basic:
|
|
```yaml
|
|
steps:
|
|
- uses: actions/checkout@v2
|
|
- uses: actions/setup-go@v3
|
|
with:
|
|
go-version: '1.16.1' # The Go version to download (if necessary) and use.
|
|
- run: go run hello.go
|
|
```
|
|
|
|
|
|
## Check latest version:
|
|
|
|
The `check-latest` flag defaults to `false`. Use the default or set `check-latest` to `false` if you prefer stability and if you want to ensure a specific Go version is always used.
|
|
|
|
If `check-latest` is set to `true`, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, a Go version will then be downloaded. Set `check-latest` to `true` if you want the most up-to-date Go version to always be used.
|
|
|
|
> Setting `check-latest` to `true` has performance implications as downloading Go versions is slower than using cached versions.
|
|
|
|
```yaml
|
|
steps:
|
|
- uses: actions/checkout@v2
|
|
- uses: actions/setup-go@v3
|
|
with:
|
|
go-version: '1.14'
|
|
check-latest: true
|
|
- run: go run hello.go
|
|
```
|
|
|
|
## Matrix Testing:
|
|
```yaml
|
|
jobs:
|
|
build:
|
|
runs-on: ubuntu-latest
|
|
strategy:
|
|
matrix:
|
|
go: [ '1.14', '1.13' ]
|
|
name: Go ${{ matrix.go }} sample
|
|
steps:
|
|
- uses: actions/checkout@v2
|
|
- name: Setup go
|
|
uses: actions/setup-go@v3
|
|
with:
|
|
go-version: ${{ matrix.go }}
|
|
- run: go run hello.go
|
|
```
|
|
|
|
### Supported version syntax
|
|
The `go-version` input supports the following syntax:
|
|
|
|
Specific versions: `1.15`, `1.16.1`, `1.17.0-rc2`, `1.16.0-beta1`
|
|
SemVer's version range syntax: `^1.13.1`
|
|
