GitHub Action to compile Erlang files to executable (.exe) or run them in debug mode. This action will automatically detect and download the dependencies needed by your Erlang code.

• ✅Automatically detects dependencies** from your Erlang files
• ✅Download dependencies** via Hex package manager
• ✅Handles various Erlang file types** dynamically
• ✅Compile to executable** with all dependencies
• ✅Debugging mode for development
• ✅Supportsmultiple files in one project
• ✅ Automatically create build directories

Create a workflow file .github/workflows/erlang-build.yml in your repository with the following content:

name: Build Erlang Project

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]
  workflow_dispatch:

  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      
      - name: Build Erlang Project
        uses: 4211421036/[email protected]
        with:
          erlang-source: './src'  # Path ke file atau direktori Erlang Anda
          build-mode: 'build'     # 'build' untuk executable, 'debug' untuk debugging
          output-dir: './build'   # Direktori output (akan dibuat otomatis)
          erts-version: '25.0'    # Versi Erlang/OTP (opsional)
          hex-packages: 'cowboy,jsx,lager'  # Tambahan Hex packages (opsional)

1.Dynamic Dependency Analysis:

• Action will automatically analyze Erlang files to find modules that are used
• Detects include files and module calls

2.Dependency Management:

• Uses rebar3 to download required dependencies.
• Supports adding additional hex packages via parameters

3.Build Process:

• Compiles all found Erlang files
• Creates a complete Erlang application with dependencies
• Generates an executable that can be run independently

4.Debug Mode:

• Runs Erlang files in debug mode
• Automatically detects start/0 functions if present

- name: Build Single Erlang File
  uses: 4211421036/[email protected]
  with:
    erlang-source: './src/my_web_app.erl'
    build-mode: 'build'
    hex-packages: 'cowboy,jsx'

- name: Build All Erlang Files
  uses: 4211421036/[email protected]
  with:
    erlang-source: './src'
    build-mode: 'build'

- name: Debug Erlang Application
  uses: 4211421036/[email protected]
  with:
    erlang-source: './src'
    build-mode: 'debug'
    hex-packages: 'lager,jsx,cowlib'

• This action uses Erlang/OTP and rebar3 for dependency management.
• Build mode will generate an executable package containing the Erlang runtime
• Automatic dependency detection works best for standard modules and popular hex packages
• For custom dependencies, use the hex-packages parameter
