Setup Guide

Unfortunately wasm-pack does not support compiling C dependency with stdlib. We have to use emcc.

We have to use web-tree-sitter

~~

1. Install emcc
2. rustup target add wasm32-unknown-emscripten
3. cargo install -f wasm-bindgen-cli
4. EMCC_CFLAGS="-s ERROR_ON_UNDEFINED_SYMBOLS=0 --no-entry" cargo build --target wasm32-unknown-emscripten
5. wasm-bindgen --target web ../../target/wasm32-unknown-emscripten/debug/ast_grep_wasm.wasm --out-dir pkg
