To incorporate new changes into the Unison grammar, you will need to look into the source grammar: src/unison.tmLanguage.yml.

Once your modifications are in place, you can generate the derived grammars located in grammars/ by running:

npm install

Once the derived grammars are generated, you can write tests for your modifications taking one of the file in test/ as an example. You can then run the tests with:

npm test

unison-tmlanguage's Issues

Properly highlight [Int]

in [+4, +3, +4] the left brace is not highlighted

Add a contribution guide

It can be difficult to differentiate between the source and the derived grammars.

Highlight multiline strings

Make the CI depend on the source syntax

Atm, the CI depends on a derived syntax which means changes to the source syntax which are not reflected in the derived syntaxes don't make the CI fail.

Highlight characters

?a

Higlight handle keyword

handle
  doOneThing
  doAnotherThing
with
  theHandler

Upgrade vscode-textmate

The latest version use Promises and my knowledge of TypeScript is too limited for now to work with that in the tests.

Highlight base types

Such as List, Nat and co.

Support doc

unisonweb/unison#914 (comment)

Properly highlight record types

type Vec = {x: Int, y: Int, z: Int}, { and } are mismatched.

Highlight && and ||

Highlight cases

sum = cases
  [] -> 0
  hd +: tl -> hd + sum tl
