Thanks!

Hi @v217 !

Thanks for your request. It looks like a lot of work, and also to run against the spirit of srgn a bit. The "prepared queries" are a large part of what makes srgn useful in my mind, and with a pluggable aka custom language, they couldn't be offered anymore. At that point, using tools like ast-grep or the tree-sitter CLI directly seems like suitable solutions.

Hi Alex!
Thanks for srgn!
The motivation for this issue was, that in ast-grep you can't (like in srgn) use “tree-sitter queries” to select matches. If you don't write grammars, that is probably not an issue, but if you want to customize the tooling for a language, you have to remember two queries: The tree-sitter query and the query used, e.g., in ast-grep. That's in my view the main advantage of srgn over ast-grep, but this advantage mainly is important, if you are familiar with the tree-sitter queries, e.g., you most likely wrote or modified your own custom grammar. So even for a subset of features of srgn custom language support might be motivated?
Or, as you mentioned, using tree-sitter directly in your scripts.
