Swifty Linux Action

This action sets up a Swift environment on Linux.

Note that Linux is currently the only system supported by this action. Running it on other platforms will fail.

Inputs

release-version

The (released) Swift version (e.g. 5.6) to install.
If github-token is also set, it will automatically resolve to the latest matching version.
Note: If given, branch-name and version-tag are ignored.

branch-name

The branch of the Swift version to install (e.g. swift-5.6.1-release).
Required if release-version is not set!

version-tag

The version tag of the Swift version to install (e.g. swift-5.6.1-RELEASE).
Required if release-version is not set!

platform

The platform for which to install the Swift version (e.g. ubuntu20.04). Note that the github-actions notations with a dash (e.g. ubuntu-20.04) is also valid.
If not given, the action tries to determine the system it currently runs on. Note that this might fail if Swift is not available on this platform, or it's not yet supported by this action!.

skip-dependencies

Whether the installation of dependencies (currently via apt) should be skipped.
Default: false

skip-gpg-check

Whether the GPG check should be skipped.
Default: false

github-token

The token to use for searching for the latest matching release. Can be set to ${{secrets.GITHUB_TOKEN}}.
Default: ${{ github.token }}

Outputs

install-path

The path where Swift was installed.
Note that this can usually be ignored, since swifty-linux-action adds the ${{install-path}}/usr/bin to the PATH environment variable.

full-version

The full version of Swift that was installed (e.g. swift-5.6.1-RELEASE).
This can be used to narrow down for example caches across builds.

Example Usage

In general, the release-version input parameter should be used to install a final release of Swift.
To for example install Swift 5.6.1, use the following snippet:

uses: sersoft-gmbh/swifty-linux-action@v3
with:
    release-version: 5.6.1

If you automatically want to install the latest matching version, also provide the github-token input. This will search for the latest matching release using the following rules:

• '5' -> Finds the latest swift-5.x.y release.
• '5.6' -> Finds the latest swift-5.6.x release.

To for example install the latest Swift 5.4.x release, use the following snippet:

uses: sersoft-gmbh/swifty-linux-action@v3
with:
    release-version: '5.6'
    github-token: ${{secrets.GITHUB_TOKEN}}

However, swifty-linux-action also supports installing other snapshots using the branch-name and version-tag input parameters.
So, to for example install the Swift 5.7 development snapshot built on 13th of June 2022, use the following snippet:

uses: sersoft-gmbh/swifty-linux-action@v3
with:
    branch-name: swift-5.7-branch
    version-tag: swift-5.7-DEVELOPMENT-SNAPSHOT-2022-06-13-a
