Hi Guix, I think it’s a bit difficult to install the Guix Workflow Language at this point and I’d like to change that.
Currently, new sub-commands for Guix are looked up by module name on the Guile load path. When installing the “gwl” package, though, the Guile load path is not automatically altered, so users need to set it up by themselves. The load path is only altered automatically when users install the “guile” package. This is not a good recommendation because users may have Guile 2.2 in their profile, and not Guile 3.0 or whatever version may be needed by the extension. I wonder if we can make this a little nicer by letting Guix look for sub-command scripts in directories that are listed in an environment variable, such as GUIX_EXTENSIONS_PATH. The “guix” package would set this search path and packages wanting to provide a sub-command (such as “guix workflow” or “guix home”) would arrange to have their scripts placed in that sub-directory of their outputs. What do you think? -- Ricardo
