Here it is redone. This time, I didn't touch the Common Lisp or R uglify business and just made a new one. The R people are welcome to update their packages to use the up to date their UglifyJs. I took your advice and put a public uglifyjs variable in uglifyjs.scm. That way when UglifyJs is rewritten in Rust, the same (gnu packages uglifyjs) module can be used. ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Monday, July 12th, 2021 at 7:52 AM, Efraim Flashner wrote: > This should be two patches, one to add node-uglify-js and one to switch > > over to the new version.
