Python Ruff Linter for TextMate2

Ruff is an extremely fast Python linter, written in Rust. This is the TextMate bundle implementation of ruff linter with fantastic features 🎉

---

Installation

You need to install ruff. I prefer brew. It’s also available via pip. Set the TM_PYRUFF variable to your ruff binary. There is a fall-back mechanism, if you have already installed ruff, bundle check the command existance with command -v ruff if TM_PYRUFF is not set. If both fails, you need to set the value of TM_PYRUFF by hand :)

brew install ruff
cd "${HOME}/Library/Application\ Support/TextMate/Bundles/"
git clone https://github.com/vigo/textmate2-ruff-linter.git Python-Ruff-Linter.tmbundle

TextMate sometimes doesn’t apply environment variable creation from command-line. If this doesn’t work, you need to apply/set manually from TextMate > Settings > Variables pull down menu.

$ defaults write com.macromates.TextMate environmentVariables \
    -array-add "{enabled = 1; value = \"$(command -v ruff)\"; name = \"TM_PYRUFF\"; }"

# enable auto fix
$ defaults write com.macromates.TextMate environmentVariables \
    -array-add "{enabled = 1; value = \"true\"; name = \"TM_PYRUFF_ENABLE_AUTOFIX\"; }"

You can set environment variables on a project basis if you prefer. For this, you can use the .tm_properties file under anywhere in your project root:

.tm_properties example:

TM_PYRUFF=/path/to/bin/ruff
TM_PYRUFF_ENABLE_AUTOFIX=1   # if you want to enable autofix by default

For older users like myself, you can define the tooltip to make it easier to read:

defaults write com.macromates.TextMate NSToolTipsFontSize 24

Bonus

When you press ⌥ (option) + R error reporting pops. TextMate’s built-in markdown parser is super outdated, this is normal. I’ve modified the original Markdown.pl file and shared under Goodies/ folder. Just copy the file under correct location:

# backup the original first :)
cp "~/Library/Application Support/TextMate/Managed/Bundles/Bundle Support.tmbundle/Support/shared/bin/Markdown.pl" "~/Library/Application Support/TextMate/Managed/Bundles/Bundle Support.tmbundle/Support/shared/bin/Markdown-original.pl"

# replace with new one.
cp Goodies/Markdown.pl "~/Library/Application Support/TextMate/Managed/Bundles/Bundle Support.tmbundle/Support/shared/bin/"

You should see fancy code-blocks parsed as expected:

TextMate Variables

Variable	Default Value	Description
ENABLE_LOGGING		Set for development purposes
TM_PYRUFF		Binary path of ruff
TM_PYRUFF_DISABLE		Disable bundle
TM_PYRUFF_ENABLE_AUTOFIX		Autofix fixables on save
TM_PYRUFF_OPTIONS		Pass custom options if there is no config file
TM_PYRUFF_GFM_ZOOM_FACTOR	100%	Zoom factor for report errors screen

---

Usage

After setting the TM_PYRUFF variable, you need to select the language as Python Ruff.

IMPORTANT: Bundle ships with TextMate grammar: Python Ruff. You must set your language scope to Python Ruff for the bundle to function/work properly. Scope automatically loads source.python and source.python.django grammars. Due to TextMate’s callback flow, I was forced to create a separate scope. Otherwise, it would conflict with all bundles that use source.python. Due to this situation, previous version was working too slow.

When you hit ⌘ + S (save the file) bundle runs:

• Import sorting
• Code formatting
• Autofixing autofixable errors if TM_PYRUFF_ENABLE_AUTOFIX is set.

You don’t need to enable TM_PYRUFF_ENABLE_AUTOFIX by default. You can manually trigger by pressing ⌥ + A (Option + A)

If you have lint errors, you can directly navigate error by pressing ⌥ + G (Option + G). User cursor keys (Up/Down) and hit enter to jump related line:column.

Enable / Disable Bundle or Features

To completely disable the bundle, simply assign a value to TM_PYRUFF_DISABLE. This allows you to proceed as if the bundle does not exist. Additionally, if the first line of your Python file contains comment TM_PYRUFF_DISABLE:

# TM_PYRUFF_DISABLE
print('ok')

If you want to enable autofix set TM_PYRUFF_ENABLE_AUTOFIX variable (any value):

TM_PYRUFF_ENABLE_AUTOFIX=1

You can also pass extra options with using TM_PYRUFF_OPTIONS variable. If you don’t have .ruff.toml, you can set TM_PYRUFF_OPTIONS for custom format or custom check operations (via .tm_properties or TextMate > Settings > Variables):

.tm_properties file:

TM_PYRUFF_OPTIONS="--config \"format.quote-style = 'single'\""

TextMate > Settings > Variables (you don’t need to escape quotes):

TM_PYRUFF_OPTIONS  --config "format.quote-style = 'single'"

Keep in mind, TM_PYRUFF_OPTIONS passed on format and check operations.

Bug Report

Please set/enable the logger via setting ENABLE_LOGGING=1. Logs are written to the /tmp/textmate-ruff.log file. You can tail while running via; tail -f /tmp/textmate-ruff.log in another Terminal tab. You can see live what’s going on. Please provide the log information for bug reporting.

After you fix the source code (next run) bundle removes those files if there is no error. According to you bug report, you can tail or copy/paste the contents of error file to issue.

Also, while running bundle script (which is TextMate’s default ruby 1.8.7), if error occurs, TextMate pops up an alert window. Please add that screen shot or try to copy error text from modal dialog.

Logger output should look like this:

Keep in mind that when logging is enabled, there may be some performance degradation due to file I/O operations.

Personal Notes

I know and unfortunately, this wonderful editor, TextMate, is now in its final days. I could not use many of the beauties from the UI library that it spawned. The built-in Ruby 1.8.7, Ruby 2 have always been compiled according to the old CPU architecture and when I use nib files, TextMate randomly hangs and crashes at random times.

I couldn’t use the built-in autocompletion features and similar alert mechanisms. (I can generate tooltips in HTML format, but it crashes after a while).

If you are still using TextMate like me, I eagerly await your comments, bug reports, and feature requests.
