path mapping starting with "/"

[hyrious]

maybe related: dividab/tsconfig-paths#128

Me recently work on an vite app which does not support path mapping starting with '@', instead it could use '/@' (vitejs/vite#279). However this extension can not handle these paths like "/@assets/aqua.png". I think it is caused by:

gutter-preview/src/mappers/relativetoworkspacerootmapper.ts

Line 32 in e8c746b

const segments = pathName.split('/');

Me locally make some dirty works by adding these code and it seems to be working fine:

if (!firstSegment && this.aliases.indexOf('/' + segments[1]) > -1) {
    segments.shift(); // shift ""
    let aliases = this.paths['/' + segments[0]];
    if (!Array.isArray(aliases)) aliases = [aliases];
    aliases.forEach((alias) => {
        if (alias.endsWith('/')) alias = alias.substring(0, alias.length - 1);
        segments[0] = alias;
        const resolvedPath = segments.join('/');
        pathsToTest.push(resolvedPath);
    });
}
