The idea has me really excited. But how do I make this happen, so that copy-assets appears in $PATH? I am trying to do something with "guix environment" that does this, but I'm pretty confused as to how it could be done. How would you turn a gexp into a package object? Would it just be a lot of package object stuff stubbed out? >> The developer would have to explicitly run that script to have the fil= es >> copied under extlib/. > > That is a really neat use of gexps, and I guess running the script > manually would be akin to running 'bower install', so that should work. > > I envision the package recipe below, is this approximately what you wer= e > describing? > > (package > (name "mediagoblin") > (version "0.8.0") > ... > (inputs > `(("python" ,python) > ("assets" ,(web-assets jquery > videojs > bootstrap)))) > ...) Does web-assets generate that package object I assume? I tried looking for examples of other package definitions that include derivations from gexps, and couldn't find anything clear... It also isn't clear to me: is it okay for (inputs) to include things that aren't packages? I'd really like to explore this, though!
