Reindent on Save

A simple VSCode formatter extension that wraps editor.action.reindentlines.

This allows things like formatting on save and "Format Document".

Based on example code here: https://github.com/jrieken/vscode-formatter-sample.

This extension is language agnostic. So long as your language extension has indentation rules this should work for you.

Tested against VS Code 1.35.1

Supported Languages

While theoretically this will work with any programming language the built-in indentation logic in VS Code leaves much to be desired.

The following languages have been tested and will indent by default:

• Ruby
• JSON

Reindent for all file types

If you would like to reindent for all file types you will need to add "editor.formatOnSave": true to your settings.json.

To go from this:

{
    "a setting": 42,
    "another example setting": "Hello, world!",
}

to:

{
    "a setting": 42,
    "another example setting": "Hello, world!",
    "editor.formatOnSave": true
}
