add Fable support to FsLexYacc.Runtime #203

Closed dawedawe closed 2 months ago

This allows easy usage of FsLexYacc-generated lexers/parsers with Fable.

I'm a little confused what this does. Does it allow you to consume the generated pars.fs and lex.fs? Or are you generating those file with Fable? In what language did this work for you?

Yes, with this PR I can

copy the generated Lexer/Parser to a fable project
add the new FsLexYacc.Runtime package to it
compile to Javascript and use the parser in the browser (or locally with bun, of course).

No need for WASM or a full fledged .NET backend just to parse sources and give feedback to the user.

Would be really, really helpful for me to have this.

Thanks! A new release is all I need for the showcase.

dawedawe commented 2 months ago

Yeah, I'm ok with having this, thanks 🤘! (Would be cool to have a branch in https://github.com/dawedawe/agentleintroductiontofslexyacc showcasing this.)

I added a new project to showcase in the browser: https://github.com/dawedawe/agentleintroductiontofslexyacc/tree/main/src/AfLang.Js
