Hi all,
I asked a few questions today on the IRC channel about a julia import script. Just to summarize and be able to follow the subject later: - I was looking for a way to write a julia import script base on information in julia general package repository, which can be quite simple if we have a functional guile toml/ini parser included (I couldn't get my parser to work properly, but that might be fixable). - jvb shared his julia importer code here : https://gitlab.com/vjb/guix.jl - Apparently Nicolo also has a similer code. - jvb and zimoun defended that the Julia ecosystem evolves so quickly that writing a manual functional julia import script might be difficult to maintain, in particular because Julia uses an advanced resolver for its compatibilities. - My approach was a bit different but indeed didn't have the ambition to resolve compatibilities between packages (I need to check that but the check or the build phase should fail it packages are incompatible, thus when trying to build the imported package, we should now which packages should be updated if necessary). If we only restrain imports to the general package repository, then the task becomes much more simple : - from the package name, you can generate the uri of the following files - parse Project.toml to get source information - parse Versions.toml to get source hash information - parse Deps.toml to get information about dependencies Well there is no package description or such, but I think it makes a decent start for writing package information. These are all unnested toml/ini files, so if we manage to parse them with a simple function, I guess we could have such a small / limited importer. I do have the very beginning of a script here, but couldn't finish the parser : https://paste.sr.ht/~ngraves/bbeb74a720e717319344ee3c3e6ea477b378068f/manage - Maybe we could combine both by - using this limited importer if julia is not in the PATH - using a proper guix.jl importer if julia and the importer are present in the PATH or something like that ? I do not have a strong opinion about which option is more suitable, but would greatly profit from having a functional and supported julia import script. Sorry for inaccuracies if there are some, I do this from memory mostly. -- Best regards, Nicolas Graves
