```bash
# Option 1: Clone only main branch
git clone -b main --single-branch https://github.com/zackees/fastled-wasm-compiler.git
# Option 2: Clone normally then configure to exclude gh-pages
git clone https://github.com/zackees/fastled-wasm-compiler.git
cd fastled-wasm-compiler
git config remote.origin.fetch "+refs/heads/*:refs/remotes/origin/* ^refs/heads/gh-pages"
```
## Development
Run `./install` to install the dependencies.
Run `./lint` to run the linter.
Run `./test` to run the tests.
## Thin Precompiled Headers (Thin PCH)
The FastLED WASM compiler now supports Thin Precompiled Headers (Thin PCH), which provide faster rebuild times and better cacheability compared to traditional PCH.
To enable Thin PCH:
- Set the `THIN_PCH=1` environment variable
- Or use the `--thin-pch` flag with the build scripts
Example:
```bash
# Using environment variable
THIN_PCH=1 ./build_tools/build_lib.sh --all
# Using command line flag
./build_tools/build_lib.sh --thin-pch --all
```
