Hello.
Are there any plans on adding javascript support?
I wasn't thinking about it. It's just not something I use. If tree-sitter parsers were supported, then adding JS could be easy. However, I was put off by the necessity to deal with Rust and JS to try even their C parser and haven't done it, so their trees might not even be suitable for diffing.
I'm on the lookout for a patch tool whose intelligence stretches beyond linenumbers, that can be run in a post-install script.
I don't remember seeing AST patching tools. The research papers on diffing always talk about edit scripts, but the tools usually show differences or statistics on code changes. It would probably take a combination of source (unpatched) file and a tree diff to be able to apply patches to modified files.
What are you trying to patch? Is it some kind of automatically generated file?
Thanks for the swift reply.
I did some heavy alterations to a js application – little pieces of code injected here and there. Now that I'm happy with the result I'd like to apply them automatically in a build pipe every time the original js app changes.
I know there will be bugs and breaks, but I figured I have an easier life if the patch could be done with some "intelligence" as opposed to attacking mere line numbers.
Your comment lead me in a direction that winded up here: https://github.com/Vunovati/astii which might be what I need...
Keep up the good work :>

Strictly speaking it's not just line numbers. I think unchanged lines (context) in unified diffs are also taken into account. You could also try automating git-rebase
of your branch onto upstream's master
. This will effectively "update" patches to reflect upstream changes if there are no conflicts.

It's not really AST-aware, it just does source code normalization before diffing and patching, but it can help.
Keep up the good work :>
Thanks, I'll try.

Zograscope looks interesting. Are there any plans on adding javascript support?
