You can install this bundle in TextMate by opening the preferences and going to the bundles tab. After installation it will be automatically updated for you.

The commands run bin/rails in the Rails application of the current file (the closest directory with bin/rails), using the application’s Ruby version: through mise when it is installed, otherwise with the PATH from TextMate’s Preferences → Variables. If mise is installed somewhere unusual, set TM_MISE to its path in Preferences → Variables.

• Create Migration… (⌃⇧M): asks for the migration name, optionally followed by columns (AddEmailToUsers email:string:index), runs bin/rails generate migration, and opens the new migration.
• Migrate, Rollback, Redo Last Migration, Migrate to Version…, and Migration Status (⌃|): run the corresponding db:migrate tasks and show the output in a window.
• Generate Model from Migration (⌃|): in a migration that creates a table, runs bin/rails generate model with the table’s columns (without creating another migration) and opens the model. Existing files are left untouched.
• Test All, Test Current File, Test at Caret, Test Models, Test Controllers, Test Integration, and Test System (⌃\): run bin/rails test for everything, the current file’s test (app/models/user.rb → test/models/user_test.rb), the test around the caret, or a group of tests.
• Load Fixtures, Load Schema into Database, Dump Schema from Database, and Prepare Test Database (⌃|): run the corresponding db: tasks. Loading fixtures or the schema into the development database asks for confirmation first.
• Alternate File (⌥⌘↓): switches between a controller action and its view, and between a file and its test (app/models/post.rb ↔ test/models/post_test.rb, app/jobs/… ↔ test/jobs/…).
• Go to Controller, Model, View, Helper, Controller Test, Model Test, Fixture, JavaScript, and Stylesheet (⌥⇧⌘↓): open the related file of the current resource. Missing files can be created, views ask for their name.
• File on Current Line (⌥⌘↑): opens the partial, template, or layout rendered on the current line, the asset of a stylesheet_link_tag, javascript_include_tag, or image_tag, or the file of a require_relative.
• Show DB Schema for Current Class (⌃⇧⌘S) and List Columns of Model (⌥Space): show the columns of the model at the caret from db/schema.rb, or insert one of its columns or associations.
• Jump to Method Definition (⌃F): opens the definition of the method, class, association, or instance variable at the caret in app, lib, config, or test.
• Generate… (⌃|): choose one of the application’s generators, enter its arguments, and see what was generated, with links to the new files. Existing files are kept.
• Create Partial From Selection (⌃⇧H, in views): moves the selected part of a view to a new partial and renders it instead. Without a selection, shows the partials rendered by the view inline for editing; run it again to write them back. In Ruby files, ⌃⇧H is the Ruby bundle’s Format Document (RuboCop).
• Autocomplete Routes (⌥⎋): completes route helpers (posts_path, edit_post_url, …) in controllers and views. The routes are cached until a routes file changes. With the Language Server bundle and a language server for the file (such as ruby-lsp, from the Ruby bundle), its completions follow the routes, so ⌥⎋ completes methods and constants too.
• Autocomplete Foreign Key Fixture Reference (⌥⎋): completes fixture labels, e.g. author: da in a fixture or users(:da in a test. The (List) variant (⌥⇧⎋) adds to a list, e.g. tags: ruby, ra.
• Documentation for Word (⌃H): opens the Rails API documentation for the method or class at the caret, looked up in the api.rubyonrails.org search index.
• Help (⌃H): shows this list of commands.
• Migration tab triggers mcol, mind, and mtab: insert a column, index, or table change. In migrations with a down method, the reverse is inserted there. Choosing Remove / Add Column or Drop / Create Table and pressing tab twice on the placeholder completes the line from db/schema.rb, making it reversible in a change method.

The commands only use the shell and the application’s Ruby, as TextMate’s Ruby support library can’t be loaded on Apple silicon.

Grammar changes are covered by scope tests in test/syntax. Each file starts with a # SYNTAX TEST "source.ruby.rails" header, and lines with ^ markers assert the scopes of the source line above them (see vscode-tmgrammar-test). Run them with:

npm install
npm test

The command helpers have tests too, e.g. ruby test/commands/rails_navigator_test.rb (see test/commands).

The tests use the Ruby and HTML grammars from textmate/ruby.tmbundle and textmate/html.tmbundle, pinned in test/fetch-grammars to the revisions that TextMate installs.

ERB tests (*.erb) use ## as the assertion prefix, as HTML has no line comments; these lines are plain text to the HTML grammar.
