The Svelte compiler, rewritten in Rust.
This projects aims to make Svelte usable without Node.js and make the compiler blazingly fast.
This is still a big work in progress. Only a few parts of Svelte are working now and the CLI tool still needs some work.
To install with cargo, run cargo install rustle_cli" to install the alpha version of the CLI.
Run rustle_cli app.rustle to generate an app.js file. You can optionally specify a different output file with the -o flag.
You can also specify a directory for example rustle_cli src to parse all the files in that directory.
For debugging, you can print the generated AST with the -a or --ast flag and pretty print it with -p.
A lot of features still need to be implemented before rustle is ready for use. Check the examples folder or rustle/tests to get a better look at currently is supported:
