I almost got brain aneurysm thinking that the query syntax of tree-sitter and ast-grep differ.

Fortunately that's not the case, but - contrary to Internet wisdom - query syntax is not compatible between languages (parsers).

Also, ast-grep's Playground is insanely useful:

On the other hand ast-grep's pattern/rule syntax is **not** compatible with Semgrep's :(

@buherator
If your ever write a bit (just a bit) about, I would be thankful.

@joxean write about what exactly? :)

@buherator
The differences about. Or just a bit about ast-grep.

@joxean Oh OK, I'm still learning, but this usually accumulates in some tips&tricks so I'll keep that in mind!

@buherator @joxean having written too many tree-sitter queries, ast-grep looks a lot friendlier for anything that isn't syntax-highlighting.

@tmr232 @joxean Infact I'm playing with it rn because tree-sitter query CLI doesn't seem to support structured output...

@buherator @joxean I've only used it in code (TypeScript, specifically, for my function control flow project)...
