EditorConfig—TextMate PlugIn

This is a TextMate plug-in that provides support for EditorConfig. It will cause TextMate to set its editing features (e.g. tab style and size) according to a .editorconfig file you include alongside your source code.

Download it now at:

EditorConfig-TextMate only supports TextMate 2 (see below for information about TextMate 1) on MacOS 11.0 or later. It works with both Intel and Apple processors.

Feature Support

The following Editor Config features are supported:

  • root
  • indent_style ("tab" or "space")
  • indent_size
  • tab_width
  • insert_final_newline (newline is added when saving a document)
  • trim_trailing_whitespace (whitespace is trimmed when saving a document)
  • end_of_line
  • charset (the charset utf-8-bom is not supported; if you need it, please file an issue.)
  • max_line_length (sets TextMate’s “wrap column,” but does not necessarily trigger hard line wraps)


You can download a precompiled binary from:

Unzip it and double-click the editorconfig-textmate.tmplugin file to install. You can also manually drag the .tmplugin bundle into ~/Library/Application Support/TextMate/PlugIns/ in Finder.

Note: the plug-in will be loaded automatically after restarting TextMate. It will not be listed in the bundles list, since bundles and plug-ins are different things in TextMate.


If you encounter issues or are interested in seeing new features added, please file an issue:

I am also happy to take pull requests :)

TextMate 1

The current version of this plugin only supports TextMate 2, but version 0.2.6 and earlier support TextMate 1. That version only supports the following EditorConfig properties:

  • root
  • indent_style ("tab" or "space")
  • indent_size
  • tab_width

You can find older versions on the releases page.

Release Process

As of the final, non-beta TextMate 2.0 release, TextMate uses MacOS’s runtime hardening feature. That means any loaded bundles (like this plugin) must be properly signed. As of MacOS 10.15, they must also be notarized by Apple. Xcode is set up to automatically sign the bundle, but it will only automatically notarize apps. That means notarization is a manual process for this project.

You can find some general info about notarization at:

And much more detailed info about the manual notarization process at:

In practice, the process is:

  1. Build a release bundle via the “archive” command in Xcode.

  2. Use the organizer to export the bundle from the archive.

  3. Open a command-line prompt wherever the bundle is and make a zip of it:

    $ ditto -c -k --keepParent editorconfig-textmate.tmplugin
  4. Send the zip off to Apple for notarization:

    # This uploads the zip to Apple and might take a minute.
    $ xcrun notarytool submit \
        --apple-id "$NOTARIZE_USERNAME" \
        --password "$NOTARIZE_PASSWORD" \
        --team-id "$NOTARIZE_TEAM" \
    # Should result in something like:
    # Conducting pre-submission checks for and initiating connection to the Apple notary service...
    # Submission ID received
    #   id: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
    # Successfully uploaded file
    #   id: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
    #   path: /path/to/
    # Waiting for processing to complete.
    # Current status: Accepted........
    # Processing complete
    #   id: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
    #   status: Accepted

    NOTE: you’ll need to have an app-specific password for the AppleID account you are notarizing with. You can set one up on the AppleID profile page. You’ll also need to know your WWDRTeamID, which you can get by running xcrun altool --list-providers.

    The above command also assumes you have some environment variables with the appropriate values.

  5. The above command should keep running until notarization is complete. If it times out, though, you can also poll for the status on the command line:

    $ xcrun notarytool history \
        --apple-id "$NOTARIZE_USERNAME" \
        --password "$NOTARIZE_PASSWORD" \
        --team-id "$NOTARIZE_TEAM"
    # Successfully received submission history.
    #  history
    #     --------------------------------------------------
    #     createdDate: 2021-11-01T03:02:21.177Z
    #     id: f868dd45-7c71-4f48-a678-8fa1d1718d2d
    #     name:
    #     status: Accepted

    For troubleshooting help here, see the “Check the Status of Your Request” section of Apple’s docs.

  6. “Staple” the notarization to the bundle:

    # Note this runs against the actual bundle, NOT the zip
    # we uploaded when notarizing.
    $ xcrun stapler staple editorconfig-textmate.tmplugin
  7. Finally, zip up the notarized & stapled bundle and upload that to GitHub releases. Whew!

You can verify the code signature with:

$ codesign --verify --deep --strict --verbose=2 editorconfig-textmate.tmplugin
# Results in:
# editorconfig-textmate.tmplugin: valid on disk
# editorconfig-textmate.tmplugin: satisfies its Designated Requirement

And then verify that it is properly notarized for GateKeeper with:

$ spctl -a -t install -vv editorconfig-textmate.tmplugin
# Results in:
# editorconfig-textmate.tmplugin: accepted
# source=Notarized Developer ID
# origin=Developer ID Application: Rob Brackett (ABCXYZ)
