SublimeText Syntax highlighting for J.

Contains the following scopes:

• string.quoted.j (matches strings)
• constant.numeric.j (matches numbers)
• comment.line.j (matches NB. and Note to end of line)
• copula.global.j (matches =:)
• copula.local.j (matches =.)
• keyword.control.j (matches while/whilst/if/elseif/else/do/end etc.)
• identifier.noun.j (matches all primitive nouns)
• identifier.conjunction.j (matches all primitive conjunctions)
• identifier.adverb.j (matches all primitive adverbs)
• identifier.verb.j (matches all primitive verbs)
• invalid.illegal.unclosed-string.j (identifies open quotes)
• invalid.deprecated.trailing-whitespace (identifies lines with trailing whitespace)
• definition.explicit.block.j (matches multi-line verb, adverb & conjunction definitions)
• string.noun.j (matches multi-line nouns)
• comment.block.j (matches multi-line notes)
• variable.parameter.j (matches explicit references to arguments within explicit blocks)

Syntax highlighting is context aware, so keyword.control.j and variable.paramenter.j are only identified if contained within the definition.explicit.block.j context.

Supports toggling single-line comments and comment blocks.

Sublime Text 3 can use both .tmLanguage and (after build 3103) .sublime-syntax file formats for syntax highlighting. The .sublime-syntax format is more concise and easier to develop. The .sublime-syntax file here is more complete.

Add the J folder and contents to:

• "%APPDATA%/Sublime Text 3/Packages/" (Windows),
• ~/Library/Application\ Support/Sublime\ Text\ 3/Packages/ (Mac)
• ~/.config/sublime-text-3/Packages/ (Ubuntu)

or install through Package control. You may need to edit your Color Scheme Preferences to highlight all available scopes.

The .tmLanguage file in this repository is used by the github/linguist library for syntax highlighting J code on GitHub. The YAML reference version of this TextMate grammar is used for any development and the PLIST version here is generated by converting the YAML reference to PropertyList format using the TextMate Languages extension for VS Code.
