Parse RNG directly from string?

[siefkenj]

Is there a way to parse RNG source directly from a string? It appears that convertRNGToPattern only accepts a URL. (I am trying to use salve from the browser where I already have a string that has been fetched).

It's been over 2 years since I've worked on this code so it is not fresh in my memory. I'd expect you to be able to use a data: URL . See this documentation:

https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URLs

If that does not work, please let me know.

Thanks for the reply! I just tried that, but it doesn't work in the browser. I suspect it's because of the use of the fs module...Was there any ever work to get salve to run in the browser?

Salve was working in the browser. There's also this package which is made to parse DOM trees: salve-dom

I'd look here:

salve/lib/salve/parse.ts

Line 68 in d3dcea5

export async function parse(rngSource: string | Grammar,

And specifically the grammarFromSource function which is not exported. It does take a string of the RNG as input. I don't think we're exporting it, but you could write a function that works in the same way. Or use the parse function that I link to above if it does what you want. This code still uses fs but there is no reason that fs has to be used.

Otherwise, you might want to paste example code in your issue. I'm not sure I understand exactly the problem.

The code I am trying is

function processRelaxNgSchema(relaxNgSource: string) {
    const url = new URL(
        URL.createObjectURL(new Blob([relaxNgSource], { type: "text" }))
    );
    console.log("SALVE", salve.convertRNGToPattern(url));
}

and I am getting an error salve__WEBPACK_IMPORTED_MODULE_3___default() is undefined which I am guessing comes from not being able to transpile the fs module.

The parse function looks like what I need! It doesn't seem to be on the default export. Is it exported somewhere else?
