vscode-task-runner 1.3.4

Task runner for VS Code tasks.json

VS Code Task Runner

---

This is a command-line tool to execute VS Code tasks defined in the .vscode/tasks.json file. This allows you to write tasks once, and be able to run them in your editor, and in CI/CD. Basically, use .vscode/tasks.json as a Makefile.

This tool aims to be as feature-complete as possible with what VS Code supports for Windows, MacOSX and Linux. Much of the logic is taken directly from the VS Code source code and reimplemented in Python.

This pairs well with VS Code extensions that add buttons to run tasks such as actboy168.tasks.

Usage

Python 3.8+ is required.

Install with pip/pipx:

pip install vscode-task-runner

Use the command vtr on the command line and provide the label of the task(s). There must be a .vscode/tasks.json file in the working directory you run the command in. (You can also use the vscode-task-runner command instead if it makes you feel better).

Examples

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "pre-commit",
      "type": "shell",
      "command": "poetry run pre-commit run --all-files"
    }
  ]
}

$ vtr pre-commit
[1/1] Executing task "pre-commit": C:\Program Files\WindowsApps\Microsoft.PowerShell_7.3.4.0_x64__8wekyb3d8bbwe\pwsh.exe -Command poetry run pre-commit run --all-files

Additionally, for convenience, extra arguments can be tacked on to a task. For example, you can add extra settings or overrides when running in CI/CD. Continuing the example above:

$ vtr pre-commit --color=always --show-diff-on-failure
[1/1] Executing task "pre-commit": C:\Program Files\WindowsApps\Microsoft.PowerShell_7.3.4.0_x64__8wekyb3d8bbwe\pwsh.exe -Command poetry run pre-commit run --all-files --color=always --show-diff-on-failure

absolufy-imports.........................................................Passed
ruff.....................................................................Passed
black....................................................................Passed
pyleft...................................................................Passed
pyright..................................................................Passed
markdownlint.............................................................Passed

This can only be used when running a single task. You can also use -- as a separator to add additional arguments that do not start with a --. Example:

$ vtr test -- option1 option2
# This will run the task "test" with the arguments "option1" and "option2"

If your task uses an ${input:id} variable, you can provide the value for this variable as an environment variable named VTR_INPUT_{id}. Example:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "tests",
            "command": "pytest --cov=vtr/ --cov-report ${input:report_format}",
            "type": "shell"
        }
    ],
    "inputs": [
        {
            "id": "report_format",
            "description": "Coverage report format",
            "type": "pickString",
            "options": [
                "html",
                "xml",
                "annotate",
                "json",
                "lcov"
            ]
        }
    ]
}

Then in GitHub Actions:

  - name: Run tests
    run: vtr tests
    env:
      VTR_INPUT_report_format: html

The dependsOn key is also supported:

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "install",
      "type": "shell",
      "command": "poetry install --sync"
    },
    {
      "label": "build",
      "type": "shell",
      "command": "poetry build",
      "dependsOn": ["install"]
    }
  ]
}

$ vtr build

You can also use it as a pre-commit hook if desired:

repos:
  - repo: https://github.com/NathanVaughn/vscode-task-runner
    rev: v0.1.7
    hooks:
      - id: vtr
        # Optionally override the hook name here
        # name: Build & Test
        args:
          - build # put the tasks you want to run here
          - test

The pre-commit hook does not match on any file types, and and will always execute.

If using pre-commit and poetry is part of your task, you may need to add the following

"options": {
    "env": {
        "VIRTUAL_ENV": "${workspaceFolder}${pathSeparator}.venv"
    }
}

and set virtualenvs.in-project to true.

Otherwise, poetry may think the pre-commit virtual environment is your project's virtual environment.

Differences from VS Code

• If a task is of type "shell", and a specific shell is not defined, the parent shell will be used
• Only schema version 2.0.0 is supported
• If no cwd is specified, the current working directory is used for the task instead
• Does not support any extensions that add extra options/functionality
• Does not load any VS Code settings
• Extra arguments option
• VTR_INPUT_${id} environment variables
