Impossible pattern in highlights query

Sjord opened this issue · comments

The tests give an error about the highlights. E.g. when running tree-sitter test:

tree-sitter: src/./query.c:1236: ts_query__analyze_patterns: Assertion `exists' failed.

Locally, my newer tree-sitter gives the following error:

Query error at highlights.scm:231. Impossible pattern:
(type_parameter_constraint (identifier) @type)

commented

I guess the problem is that there is no identifier in a type_parameter_constraint. Should this be type_parameter_constraints_clause instead of type_parameter_constraint? @jcs090218, can you look into this?

I've removed that line for now but for me the main error was the multi-match specifier on prefix_unary so I've changed that too for now. I need to setup something where I can check the syntax highlighting locally and dig into the syntax.

PR is at #180

You should be able to test the highlights at the command line by running ‘tree-sitter highlight some-file’. I think this works on windows, but I haven’t actually tested it.
