# Set CodeQL Language Matrix

This action reads the languages API for your repository and sets the CodeQL supported languages as the job matrix for your Actions run.

## Background 

The default Actions workflow for CodeQL auto-populates the job matrix with your repo's supported CodeQL languages.  However, as new code is added to a repository, that language matrix is not updated.  You need to manually add those languages to the matrix definition to have CodeQL scan them.  

This action reads the repository languages API and adds all supported languages to the job matrix.  No additional configuration is required.

Learn more about the supported CodeQL languages [here](https://docs.github.com/en/free-pro-team@latest/github/finding-security-vulnerabilities-and-errors-in-your-code/configuring-code-scanning#changing-the-languages-that-are-analyzed)

## How to use this action

Call this action before defining the CodeQL analyze job strategy, then set the matrix to the output from the action: `${{ fromJSON(needs.create-matrix.outputs.matrix) }}`

**Example**

``` yaml

name: "CodeQL Auto Language"

on:

  push:

    branches: [ main ]

  pull_request:

    branches: [ main ]

  schedule:

    - cron: '17 19 * * 6'

jobs:

  create-matrix:

    runs-on: ubuntu-latest

    outputs:

      matrix: ${{ steps.set-matrix.outputs.languages }}

    steps:

      - name: Get languages from repo

        id: set-matrix

        uses: advanced-security/set-codeql-language-matrix@v1

        with:

          access-token: ${{ secrets.GITHUB_TOKEN }}

          endpoint: ${{ github.event.repository.languages_url }}

          

  analyze:

    needs: create-matrix

    if: ${{ needs.create-matrix.outputs.matrix != '[]' }}

    name: Analyze

    runs-on: ubuntu-latest

    permissions:

      actions: read

      contents: read

      security-events: write

    strategy:

      fail-fast: false

      matrix: 

        language: ${{ fromJSON(needs.create-matrix.outputs.matrix) }}

    steps:

    - name: Checkout repository

      uses: actions/checkout@v3

    # Initializes the CodeQL tools for scanning.

    - name: Initialize CodeQL

      uses: github/codeql-action/init@v2

      with:

        languages: ${{ matrix.language }}

 

    # Autobuild attempts to build any compiled languages  (C/C++, C#, or Java).

    - name: Autobuild

      uses: github/codeql-action/autobuild@v2

    - name: Perform CodeQL Analysis

      uses: github/codeql-action/analyze@v2

      with:

        category: "/language:${{matrix.language}}"

```      

### Excluding CodeQL Languages

It's possible you may choose to exclude specific languages from your CodeQL scans. In that case, use the `exclude` input.

Example:

``` yaml

  create-matrix:

    runs-on: ubuntu-latest

    outputs:

      matrix: ${{ steps.set-matrix.outputs.languages }}

    steps:

      - name: Get languages from repo

        id: set-matrix

        uses: advanced-security/set-codeql-language-matrix@v1

        with:

          access-token: ${{ secrets.GITHUB_TOKEN }}

          endpoint: ${{ github.event.repository.languages_url }}

          exclude: 'java, python'

```
