ast-grep VS multi-gitter

This article illustrates the usage of ast-grep, a tool designed to locate and substitute patterns in your codebase, towards easing your migration to React 19.

This looks great, thanks for building and sharing it.

Interested folks may also want to check out ast-grep:

ast-grep is a command-line tool that lets you search and transform code written in many programming languages using abstract syntax trees (ASTs). ASTs are data structures that capture the syntactic and semantic structure of source code. With ast-grep, you can write patterns as if you are writing ordinary code, and it will match all code that has the same syntactical structure. And if you need more power, you can use YAML, a rule system that allows you to write more sophisticated linting rules or code modifications.

I really like this - it means the tool is available to people with familiarity of any of those four distribution mechanisms.

You can also download pre-built binaries from their releases page: https://github.com/ast-grep/ast-grep/releases/tag/0.14.2

On top of that, they offer API bindings for it in three different languages:

- Rust (not yet stable): https://docs.rs/ast-grep-core/latest/ast_grep_core/

- JavaScript/TypeScript: https://ast-grep.github.io/guide/api-usage/js-api.html

- Python: https://ast-grep.github.io/guide/api-usage/py-api.html

It's rare to see a tool/library offer this depth of language support out of the box.

Is there an open source library that does this? Maybe something on top of ast-grep

Sounds similar to multi-gitter https://github.com/lindell/multi-gitter

It's not necessarily enforcement like the compliance pipeline but I use Multi-gitter to check if our compliance.yml is an entry in the include portion of the ci yaml file. If it's not detected it raises a MR to add it. I think this workflow would work pretty well for you too.

Multi-gitter - Run scripts across Git repos.

Yesterday I posted about multi-gitter (https://github.com/lindell/multi-gitter), but I've since found mu-repo much I much prefer. Really is fantastic for managing a large number of repos you need to perform operations on. It's lightweight and simple.

If you have a lot of repositories, in for example a GitHub org, you can do this for all of them with multi-gitter.

This is very similar to a project I created around a year ago. https://github.com/lindell/multi-gitter

Multi-gitter does also have support for other source control systems, and from what I can gather, does in general have more configuration options. But I will definitely take a look at the differences and take inspiration.
