(grammar update required) JavaScript parsing error: Error parsing source code at ...

[Sec-ant]

The JavaScript snippet below will trigger an Error parsing source code at ... error:

Code

true ? function(){return true} : function(){};

Error

Error Error parsing source code at 1:30 in /tmp/marzano-cli-d8845386-5e0c-4c15-b11f-6edccb7573ff/grit/example-1.js. This may cause otherwise applicable queries to not match.

If I add a semicolon after return true, the error disappears:

true ? function(){return true;} : function(){};

tree sitter javascript	tree sitter typescript

This seems to be a bug of the tree-sitter typescript grammar. No more errors will be thrown if I change the target language to js(js_do_not_use).

engine marzano(0.1)
language js(js_do_not_use)

`$body`

As this seems not a bug of gritql and has a workaround, I'm going to close this issue.

Thanks for the follow up, feel free to open an issue upstream and we will pull it in the next time we update the tree-sitter grammar.

FYI: The tree-sitter-typescript bug is quickly fixed by its author: tree-sitter/tree-sitter-typescript#296

Thanks, reopening this for us to update the grammar.
