HCL support coming to ast-grep! Thanks TheTeaCat's contribution!🚀 github.com/ast-grep/ast...

#ast_grep_trick ast-grep's rule is heavily inspired by CSS selectors. The rule `identifier` node is `inside` the node `call_expression` is something similar to `call_expression > identifier`

ast-grep is my personal hobby project, and all user feedback, whether good or bad, is voluntary. I don't request comments from users. If you see statements that ast-grep's community is attacking others, they are fake rumors, or more precisely, narrative trickery.

ast-grep | structural search/rewrite tool for many languages https://ast-grep.github.io/ What on earth! You can grep-replace parts of your code-base, but instead of string matching, you write AST matching expressions? That's wild.

ast-grep rule cheat sheet

Compare biomejs plugin with ast-grep in one picture: both syntax and speed.

One pic to compare ast-grep rule syntax with biome plugin syntax. The example shows the rule no-implicit-bool-jsx-attr, e.g. <div draggable /> => <div draggable={true} />

A proof of concept to run ast-grep via OXC parser

just some (probably filthy) vimscript to get ast-grep to run on the current buffer and update it cc @hd-nvim.bsky.social 👀

Ohh I didn't see that ast-grep has a VSCode extension nowadays. This tool just keeps getting better. marketplace.visualstudio.com/items/?itemN...

ast-grepは自分みたいにソフトウェアのバージョンアップや代替案への移行をよくやるものには必修科目かもしれん

🌈 vibe coding 🌈

TSLA IS DOWN! TWTR IS DOWN! ELON IS DOWN!

> No JavaScript developer knows that query language. How do you debug it? How do you test it? etc. try ast-grep maybe?

ast-grep playground now shows the wasm parser version it is using. convenient to debug parser version difference from CLI

Learning a tool can be overwhelming, but ast-grep's new UI makes it easier to explore bit by bit. 📊 Better visuals: Show more rule information 🔍 Filter examples: By rules, features, and languages 📈 Sort by complexity: Start with easy rules and explore sophisticated ones

my hand-rolled code is better than AI i guess

New ast-grep example from @tmcw.mastodon.social.ap.brid.gy ! ast-grep.github.io/catalog/tsx/...

TypeScript Puzzle!

Writing good TypeScript type definition should consider these factors: * Correct * Concise * Performant * Robust TS libs now probably pay too much attention to correctness IMHO

New ast-grep feature! You can now use `range` to select AST nodes in the source code. Why will it be useful? Find nodes using sources like Rust Analyzer, TypeScript, and other language tools! e.g. Use tsc to find errors and tell ast-grep to fix them!

Pro tip: You can combine three ast-grep flags: `--stdin` , `--inline-rules`, and `--json`, to use the tool programmatically without API! The image is an example of using bash to invoke ast-grep.
