![]() ![]() This will build the grammar files and run vscode-tmgrammar-test on all the files in the testsuite. To run the test-suite, simply call make test. The scopes of a Haskell source file, run: npx vscode-tmgrammar-test "-s" "source.haskell" "-g" "syntaxes/haskell.json" "-t" "myTestFile.hs" To generate JSON grammars (which is the format VS Code expects), we use the Node package js-yaml (requires npx in PATH): npx js-yaml haskell.YAML-tmLanguage > haskell.jsonįor testing, we use the Node package vscode-tmgrammar-test. The grammars can be found in the syntaxes directory. This project currently uses the YAML-tmLanguage format for language grammars (Haskell, Cabal, alex, happy. with developers who would write above average code in any language. We now publish an automatically generated, complete list of the textmate scopes Haskell code tends to be of high quality by construction, but for several reasons. Let me know if there are any questions about the scope assignment in thisĮxtension or if there are further scope assigments you'd like to see added. With version 3.0.0 some new tm scopes were added, such that now record and GADT definitions can beĭistinguished. Use Haskell specific rules, or are aware of a theme with Haskell specific rules, feel free to get in Rules and how changes to this extension affect such themes. I recently realized that I am woefully unaware of whether there are any themes with Haskell-specific Result different tokens can end up with identical colours.įor a theme that supports all the scopes provided by this extension, see the Unfortunately many themes have incomplete support for the different TextMate scopes, and as a This extension provides TextMate scopes for use in syntax highlighting, but the colours displayed If you happen to notice bugs or have suggestions for improvements visit the issue The syntax file from the Haskell TextMate bundle.Īdditionally there is support for Cabal files (.cabal) via a concoction of my own.Īlso adds automatic indentation after where, do, -> etc. This is a (now heavily) modified version of 'ghc') installed, then you can save the example to a text file called 'calendar.hs' and then run the following command at a command line: runghc calendar. Syntax highlightingĪdds syntax highlighting support for Haskell (.hs and. If you have the Glasgow Haskell compiler (i.e. Cabal, Happy and Alex) in Visual Studio Code. Syntax highlighting support for Haskell and associated languages (e.g.
