Patterns contains the array of regex patterns that will determine how the file is tokenized. We're interested in highlighting the Flight Manual's Markdown files, so add the md extension to the list and remove the others. Rename it to Flight Manual.įileTypes is an array of filetypes that language-flight-manual should highlight. Again, this name should describe what the grammar package is highlighting. Name is the user-friendly name that is displayed in places like the status bar or the grammar selector. This should generally describe what language your grammar package is highlighting for example, language-javascript's scopeName is source.js and language-html's is. ScopeName is the root scope of your package. This is the main file that we will be working with - start by populating it with a boilerplate template. Now create a new folder called grammars, and inside that a file called flight-manual.cson. Furthermore, in package.json, remove the activationCommands section. Go ahead and delete the keymaps, lib, menus, and styles folders. The default package template creates a lot of folders that aren't needed for grammar packages. Tip: Grammar packages should start with language. Select 'Package Generator: Generate Package,' and you'll be asked for the path where your package will be created. To get started, press Cmd+Shift+P Ctrl+Shift+P and start typing 'Generate Package' to generate a new grammar package. Whichever one you decide to use is up to you, but this tutorial will be written in CSON. Grammar files are written in the CSON or JSON format. the docs for the Oniguruma regex engine.contains a cheat sheet for various regex expressions.provides a comprehensive regex tutorial.

Note that Atom uses the Oniguruma engine, which is very similar to the PCRE or Perl regex engines. TextMate Grammars depend heavily on regexes, and you should be comfortable with interpreting and writing regexes before continuing. Note: This tutorial is a work in progress.
