Would be nice to have an online playground with nimbleparse like:

• https://yhirose.github.io/cpp-peglib/
• https://chrishixon.github.io/chpeg/playground/
• https://peggyjs.org/online.html
• https://mingodad.github.io/CocoR-Typescript/playground

This is also what ratmice/nimbleparse_lsp#6 is about, my original plan there of porting the lsp to a vscode web-extension has turned out to be a fairly difficult though, there is a project using the same underlying lsp library which does run on monaco so that might be a faster way forward.

I was thinking in something like:

#[no_mangle]
pub extern "C" fn lrpar_main(yacc_src: &str, lex_src: &str, input: &str, quiet: bool, recoverykind_str: &str, yacckind_str: &str) -> str {
}

As an exported function from nimbleparse that way we could have plyaground with only one exported function where all output is buffered and returned as String.

If someone wanted to host such a thing, that would be fine, but I won't be able to host myself, I'm afraid.

This can be hosted on github pages like :

• https://yhirose.github.io/cpp-peglib/
• https://chrishixon.github.io/chpeg/playground/
• https://mingodad.github.io/CocoR-Typescript/playground

If someone wanted to make a PR to do so I'm game!

[mingodad]

I could try but I'm not familiar with rust if you could implement:

#[no_mangle]
pub extern "C" fn lrpar_main(yacc_src: &str, lex_src: &str, input: &str, quiet: bool, recoverykind_str: &str, yacckind_str: &str) -> str {
}

Then I could try to create/adapt the Javascript/Html needed to host the playground on github pages.

This is, effectively, what cargo run --release --bin nimbleparse does:

$ cargo run --release --bin nimbleparse
    Finished release [optimized] target(s) in 0.05s
     Running `target/release/nimbleparse`
Too few arguments given.
Usage: nimbleparse [-r <cpctplus|none>] [-y <eco|grmtools|original>] [-q] <lexer.l> <parser.y> <input file>

So maybe that's enough as-is?

It would be if there was a way to create a virtual filesystem like it's possible with emscripten but I didn't found anything like that for rust.
