Interesting. I think it could grab information locally (from the available =E2=80=98guix pull=E2=80=99 generations) and from the Guix Data S= ervice. However, it might give the false idea that users can pick package versions independently (as in: I want esbuild X, GCC Y, and Go Z), which is not really the case: packages are interrelated. > I make this proposal because I perceive the following advantages: > - It makes no the assumption that the operator knows what git is, cares > about the internal git structure of Guix, wants to read git commits, or > wants to master the details of the internal "inferiors" mechanism we use > to provide this functionality. Yeah, I think =E2=80=98guix git log=E2=80=99 can be very useful for develop= ers, but is not a great UI for browsing package history for the reasons you give. > - It answers directly the operator's practical questions rather than > providing oblique advice which depend upon the operator's tacit > knowledge. > - The user can act immediately upon the output of the command to create > a manifest that represents the software they want to use. Yes, that is a really nice property, as long as it doesn=E2=80=99t suggest = that one can do that with any number of packages at once. (Whether =E2=80=98-m= =E2=80=99 should accept rec files or not can be treated separately.) Thanks, Ludo=E2=80=99.
