Github Action for Lua and LuaJIT

`leafo/gh-actions-lua`

Update Nov 18, 2020: You must use version 8.0.0 or greater as GitHub has deprecated older versions of the actions core libraries.

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

Other Lua GitHub actions:

leafo/gh-actions-luarocks
- inputs: luarocksVersion

Usage

Install Lua: (Will typically default to the latest release, 5.4.2 as of this readme)

- uses: leafo/gh-actions-lua@v8.0.0

Install specific version of Lua:

- uses: leafo/gh-actions-lua@v8.0.0
  with:
    luaVersion: "5.1.5"

Install specific version of LuaJIT:

- uses: leafo/gh-actions-lua@v8.0.0
  with:
    luaVersion: "luajit-2.1.0-beta3"

Inputs

`luaVersion`

Default: "5.4"

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

Examples of versions:

"5.1.5"
"5.2.4"
"5.3.5"
"5.4.1"
"luajit-2.0.5"
"luajit-2.1.0-beta3"
"luajit-openresty"

The version specifies where the source is downloaded from:

luajit-openresty — will allways pull master from https://github.com/openresty/luajit2
Anything starting with luajit- — from http://luajit.org/download.html
Anything else — from https://www.lua.org/ftp/

Version aliases

You can use shorthand 5.1, 5.2, 5.3, 5.4, luajit version aliases to point to the latest (or recent) version of Lua for that version.

`luaCompileFlags`

Default: ""

Additional flags to pass to make when building Lua.

Example value:

- uses: leafo/gh-actions-lua@master
  with:
    luaVersion: 5.3
    luaCompileFlags: LUA_CFLAGS="-DLUA_INT_TYPE=LUA_INT_INT"

Note that compile flags may work differently across Lua and LuaJIT.

Full Example

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: leafo/gh-actions-lua@v8.0.0
      with:
        luaVersion: "5.1.5"

    - uses: leafo/gh-actions-luarocks@v4.0.0

    - 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 luaVersion 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.

Version build matrix

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: leafo/gh-actions-lua@v8.0.0
      with:
        luaVersion: ${{ matrix.luaVersion }}
