CodeMirror 6 language package template

This is an example repository containing a minimal CodeMirror language support package. The idea is to clone it, rename it, and edit it to create support for a new language.

Things you'll need to do (see the language support example for a more detailed tutorial):

• git grep EXAMPLE and replace all instances with your language name.

• Rewrite the grammar in src/syntax.grammar to cover your language. See the Lezer system guide for information on this file format.

• Adjust the metadata in src/index.ts to work with your new grammar.

• Adjust the grammar tests in test/cases.txt.

• Build (npm run prepare) and test (npm test).

• Rewrite this readme file.

• Optionally add a license.

• Publish. Put your package on npm under a name like codemirror-lang-EXAMPLE.
