  • Go into Edit > Preferences > Modules
  • Choose mod-script-pipe (which should show New) and change that to Enabled.

Getting Started

All the commands assume that the Audacity application is up and running; That is mandatory as we communicate with Audacity's pipe to execute all the commands.

NOTE: See the GitHub Actions Tests Workflow to check it in action.

Remove spaces between clips

This command copies the original file and removes spaces (gaps) between audio clips from the copied file.

audacity_scripting clean-spaces --path "/path/to/my_project.aup3"

Send a command to Audacity

Send a command to Audacity according to Audacity's Scripting Reference.

audacity_scripting do-command --command "Select: Tracks=0.0 Start=0.0 End=0.0"

Development Requirements

• macOS

  • Install HomeBrew Package Manager

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
    

  • Install required packages with HomeBrew

    brew install make
    

• Windows

  • Install Chocolatey Package Manager

  • Install required packages with Choco

    IMPORTANT: Open a PowerShell window with elevated permissions (As Administrator)

    choco install -y make
    

From now on, we'll use make commands to develop and build this Python package locally.

1. Fork this repository on GitHub

2. Git clone your forked repository

3. Add this repository as a "source" remote

   cd audacity-scripting
   

   git remote add source https://github.com/unfor19/audacity-scripting.git
   

   Check git remotes

   git remote -v
   

   Assuming you are willywonka, here's the desired output:

   origin https://github.com/willywonka/audacity-scripting.git (fetch)
   origin https://github.com/willywonka/audacity-scripting.git (push)
   source https://github.com/unfor19/audacity-scripting.git (fetch)
   source https://github.com/unfor19/audacity-scripting.git (push)
   

4. Prepare .VENV directory - This step also installs the latest version of pip and wheel

   make venv-prepare
   

5. IMPORTANT: The Makefile activates .VENV for any venv- target.

6. Install this package's development requirements.txt in .VENV

   make venv-install
   

7. Install this package in edit mode

   IMPORTANT: For any change in ./src/audacity_scripting/cli/, it's best to re-run this command to update the CLI commands; see Click Framework.

   make venv-install-edit
   

You can now start the development process!

Development Process

1. Checkout to a new branch feature/my-awesome-feature
2. (Optional) Add a new Python package and update ./requirements.txt accordingly

   make venv-install PACKAGE_NAME=click==8.1.7
   

   make venv-requirements-update
   

3. Add tests on your feature in ./tests; all tests are based on the Python's unittest framework
4. Run tests - This wrapper command kills existing Audacity instances, cleans up test outputs, starts Audacity, and then starts the tests.

   make wrapper-run-test
   

5. Commit changes to your cloned fork

   git commit -am "added an awesome feature"
   

6. Create a GitHub Pull Request from your fork to the source repository.

Syncing with the "source" code

You've already added source as a git remote, to sync from source to your current branch, execute this command:

git pull source main

Following that, you might need to handle some merge conflicts, but that's it; you're up-to-date with the latest version of the source code.
