Support file: protocol

[sapphi-red]

Currently file protocol (e.g. /__open-in-editor?file=file%3A%2F%2F%2FC%3A%2Ffoo.js:13:24) is not supported.

Because using fileURLToPath in browser requires a polyfill, I think it would be nice if file protocol is supported.

afaik that is impossible; the file: protocol is handled by your browser, meaning you can't bind some node code to a file URL. you'd need to patch your browser, or patch your kernel's filesystem read operations

I'm not saying that launch-editor should intercept requests accessing to URLs with file: protocol which is impossible as you say.
I'm saying that I want launch-editor to support file URLs to be accepted as the first parameter.

import launch from 'launch-editor'
launch('file:///foo/bar/foo.js:12:34')

ah i see - one way to implement this would be something like:

const toFsPath = (path:string) => (new URL(path,'file:///')).pathname;

which works with both file:///'s (ie toFsPath('file:///foo/bar/foo.js:12:34');) aswell as raw paths, like toFsPath('/foo/bar/foo:12:34');
