Support for Modrinth ModPacks

[ModProg]

Enhancement Type

New server type

Describe the enhancement

Currently, Modrinth mod packs are still in alpha, but as far as I can tell the format seems to be stable.
It is described here: https://docs.modrinth.com/docs/modpacks/format_definition/

That file format looks awesome. I wish all the modpacks would align on this format.

I'll probably implement this within https://github.com/itzg/mc-image-helper, but will track integration with this issue.

...and just noting the CDN URL seems to be:

https://cdn.modrinth.com/data/{projectId}/versions/{version}/{name}-{version}.jar

EDIT this note is no longer relevant, due to API usage to locate project assets.

FYI the initial steps towards Modrinth modpack support is included in #1577

Modrinth admin here -- just wanted to let it be known that the format of CDN URLs should not be relied upon, since the file name can be whatever the author wants. The exact CDN URL can be obtained via use of the Get version from hash route (example) or from the Get a version route (example) depending on what information you already have.

I'm not sure how relevant it is, but you might also get some use out of the Latest versions of multiple project from hashes, loader(s), and game version(s) route (wow that's a mouthful), looking at how the initial implementation was done.

If you've got any other questions or issues with Modrinth feel free to get in touch with me, here or Discord (Emmaffle#1787) or email (emmaffle@modrinth.com) :)

Thanks @wafflecoffee . Please disregard my note about CDN structure. I'm already using the API as you described for retrieval of individual mod project files

When will modpack support leave alpha? To be honest I am hesitant to put more effort into this until I see traction with the modpacks published on Modrinth; however, I'm assuming traction will be slow until it leaves alpha.

[triphora]

Alpha doesn't really mean that it's unstable; the pack format is set in stone until we bump it to 2. More or less, it's meant as an indicator that our plans for modpacks are not yet complete. Once https://github.com/modrinth/theseus is complete, that's when it'll leave alpha.

[itzg]

Cool, I'll works towards modpack retrieval and extraction shortly.

Is this still planned as a feature? Would be great to have a way to pull down a modrinth pack!

It sure is @lizardfish0
