Incompatibility with rollup sourcemaps

[GauBen]

Hi!

I'm trying to use esrap in a Rollup plugin's transform hook. It works perfectly for the code, but sourcemaps are not generated. After a quick investigation, it turns out esrap uses loc and range for sourcemaps, while Rollup uses start and end.

import { print } from "esrap";

const plugin = {
  name: "dummy-plugin",

  transform(code, id) {
    // Works perfectly for the code, fails for sourcemaps
    return print(this.parse(code), { sourceMapSource: id, sourceMapContent: code });
  },
};

Is there a way to make esrap and Rollup work together? ^{Especially since you created both tools 👀}

Thanks!

Is it still the case? We have some tests that generate source maps.
