Github Action to install Lua/LuaJIT on Unbutu/macOS/Windows.

Builds and installs Lua into the .lua/ directory in the working directory using CMake. Adds the .lua/bin to the PATH environment variable so lua can be called directly in workflows.

This project is hightlly inspired by (and this README is initially copied from) leafo/gh-actions-lua. The difference is this project use CMake to support Unbutu/macOS/Windows.

Many thanks to leafo!

Install Lua:

Will install the latest stable release of PUC-Rio Lua.

- uses: xpol/setup-lua@v1

Install specific version of Lua:

- uses: xpol/setup-lua@v1
  with:
    lua-version: "5.1.5"

Install specific version of LuaJIT:

- uses: xpol/setup-lua@v1
  with:
    lua-version: "luajit-2.0.5"

Default: "5.3.5"

Specifies the version of Lua to install. The version name instructs the action where to download the source from.

All supported of versions:

• "5.3.5"
• "5.3.4"
• "5.3.3"
• "5.3.2"
• "5.3.1"
• "5.3.0"
• "5.2.4"
• "5.2.3"
• "5.2.2"
• "5.2.1"
• "5.2.0"
• "5.1.5"
• "5.1.4"
• "5.1.3"
• "5.1.2"
• "5.1.1"
• "5.1.0"
• "luajit-2.0.5"
• "luajit-2.1.0-beta3"
• "luajit-2.1.0-beta2"
• "luajit-2.1.0-beta1"
• "luajit-2.0.4"
• "luajit-2.0.3"
• "luajit-2.0.2"
• "luajit-2.0.1"
• "luajit-2.0.0"

Note: Beta versions will removed when the stable version is released.

You may also need an action to install luarocks:

• leafo/gh-actions-luarocks
  • inputs: luarocksVersion

This example is for running tests on a Lua module that uses LuaRocks for dependencies and busted for a test suite.

Create .github/workflows/test.yml in your repository:

name: test

on: [push]

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@master

    - uses: xpol/setup-lua@v1
      with:
        lua-version: "5.1.5"

    - uses: leafo/gh-actions-luarocks@v2

    - name: build
      run: |
        luarocks install busted
        luarocks make

    - name: test
      run: |
        busted -o utfTerminal

This example:

• Uses Lua 5.1.5 — You can use another version by chaning the lua-version varible. LuaJIT versions can be used by prefixing the version with luajit-, i.e. luajit-2.1.0-beta3
• Uses a .rockspec file the root directory of your repository to install dependencies and test packaging the module via luarocks make

View the documentation for the individual actions (linked above) to learn more about how they work.

You can test against multiple versions of Lua using a matrix strategy:

jobs:
  test:
    strategy:
      matrix:
        luaVersion: ["5.1.5", "5.2.4", "luajit-2.1.0-beta3"]

    steps:
    - uses: actions/checkout@master
    - uses: xpol/setup-lua@v1
      with:
        lua-version: ${{ matrix.luaVersion }}
