Maya Module Actions

Three actions for streamlining the compiling and distribution of maya modules: getMayaDevkit, mesonBuild, packageMayaModule

Get Maya Devkit

Downloads (and caches) the maya devkit for all the versions and updates you use in your matrix

Basic Usage:

- name: Get Maya Devkit
  id: get-devkit
  uses: blurstudio/mayaModuleActions/getMayaDevkit@v1
  with:
    maya: 2023
    update: 3
    cache: true

This action also outputs the devkit path, which can be accessed like so (assuming the id is set to get-devkit)

${{ steps.get-devkit.outputs.devkit-path }}

And, just for convenience, it also outputs the maya plugin extension for the current operating system

${{ steps.get-devkit.outputs.plugin-ext }}

Meson Build

This is just a conveneince wrapper for setting up and building with Meson (vs CMake)

Basic Usage:

- name: Build
  uses: blurstudio/mayaModuleActions/mesonBuild@v1
  with:
    setup-args: >
      -Dmaya:maya_version=${{ matrix.maya }}
      -Dmaya:maya_devkit_base=${{ steps.get-devkit.outputs.devkit-path }}
      --buildtype release
      --backend ninja

This is not maya specific, so you can re-use this elsewhere if you like. And it automatically detects a Windows build, and sets up the visual studio environment for compiling. You could invoke meson directly, But dealing with the different shells required is a pain, and this action handles that part cleanly.

Package Maya Module

Grabs all the compiled artifacts, and builds a .mod file for distributing your plugins.

Basic Usage:

- name: Package
  uses: blurstudio/mayaModuleActions/packageMayaModule@v1
  with: 
    module-name: TwistSpline
    folder-list: scripts icons
    version: v1.2.3

This would upload an artifact named TwistSpline-v1.2.3.zip.

Requirements

All of your plugin artifacts must be named like this

<operatingSystem>-<mayaYear>-plugin/<pluginName>.mll

Any Python modules that go with your plugin must be named like this

<operatingSystem>-<mayaYear>-pyModule/<pythonModule>.pyd

OR

The python modules may be compiled with the limited api, and can therefore be reused across all maya versions. If so, pass py-limited-api: true, and build the python modules without a year in their folder structure

<operatingSystem>-pyModule/<pythonModule>.pyd

Full Example

Here's an example of a full yaml that will build, package, and upload artifacts, and release them when properly tagged.

name: build

on:
  push:
    branches: [ master ]
    tags:
      - v*
  pull_request:
    branches: [ master ]

#       update: 2
