Languages are supported through language-specific queries. Each language needs at lease one query which matches the most common delimiters, usually (, ), [, ], {, }, < and >. Read :h ts-rainbow-custom-queries in the manual first to understand how to write queries. Your query should meet the following criteria:
- Named
rainbow-parens - Few if any
@intermediatecapture groups; we do not want the default query to be too vibrant - Write one or more files in the language under
test/highlight/<lang>(where<lang>is the language) - The test code must have at least one instance of each pattern in the query
- The test code must not have parsing errors
- The test code should ideally have multiple levels of nesting
- The test code should compile and have no linter errors if that is feasible (this is not a hard rule though)
If there are many test cases or if the code becomes too verbose feel free to created multiple test files.
