Currently, large modpacks such as the Versatile v7.5 pack triggers a SIGABRT caused by the following

runtime/cgo: pthread_create failed: Resource temporarily unavailable

This is caused by the value in the --dl-threads flag not being used in the Downloader. Here is a snippet of the relevant code from main.

I use local packs for my server since i distribute mods with automodpack rather than by having people download the pack manually. I have a script that runs mrpack-install latest-pack.mrpack on every restart, and this worked until i replaced a mod with a mutually incompatible one. it was at this point i realized that the program only deletes files when running update, and that the update command has no code path for files. Could this capability be added?

I wanted to install a pack with mrpack-install on a raspberrypi, but sadly the downloaded mods are named mods\modname.jar in are located in the server's root directory not in the mods one. I think this occures because mrpack-install isn't noticing that it is running in a linux enviroment and uses \ instead of / so the files are named instead of beeing moved.

In order not to have client-side mods, such as Embeddium, Rubidium, JEI, REI, etc...
Mods have a data on the Modrinth API that tells if the mod is client-side, server-side or both

Currently there is no automatically way with the installer to handle optional mods (that I can find in the help options). There should be an interactive (select the optional mods you want installed) and an automatic (command line options that disable all, enable all, or enable select mods) way of managing optional mods upon installation.

• Finalize concept for update behaviour
• Review packstate.json schema and implementation.
• Review implementation of update command
• Write tests with realistic test-scenarios

I noticed this tool creates a server folder and installs mods for the server. If I just copy the generated mods folder to my local game's Minecraft folder, will my local game have all the mods from the modpack?

I am trying to use this to update a pack I've been managing with it and there is a 404 for one of the mods or mod updates. Problem is, this is all I get:

mc@mineos_server:~/servers/CobblemonPlus$ /var/games/minecraft/util/mrpack-install-linux install 'Cobblemon Fabric Plus 1.4.1-plus-1.0.5.mrpack' --server-dir "${PWD}"
2024/05/17 18:50:20 http status 404

I can't tell what the mod or file is thats throwing a 404, and so i can't fix it. This is where the verbose mode mentioned in the repo docs would be needed, however in the most recent version, verbose is no longer an option:

mc@mineos_server:~/servers/CobblemonPlus$ /var/games/minecraft/util/mrpack-install-linux --version

Unsure if this was mistakenly removed or intentionally removed, but we need to be able to have more info than 2024/05/17 18:50:20 http status 404 to diagnose issues with packs.

FWIW - ATLauncher can install this version update with no errors, no 404s occur.

Github Action has new version (#50) with version option for choosing between v1 or v2 goreleaser.

Upgrading is outlined here:

Bug reproduced:

Hello, I came across this from the modrinth website. I am relatively new to linux and cannot figure out the proper command to run the install file for mrpack-install. If someone could guide me the right way that would be awesome. Sorry about the fact this probably isn't the best place to post this.

I have a modpack that my friend made, and when I try to create a server using this tool the overrides fail to extract.

Running this command:

Results in this:

Not a huge issue as the overrides can be extracted manually, but would be awesome if It can be addressed.
Cheers! Awesome tool btw!

v0.17.2-beta

c:\MCServers>mrpack-install "c:\MCServers\mrpacks\Prominence II [RPG] 2.8.4.mrpack" Installing "Prominence II [RPG]" from "c:\\MCServers\\mrpacks\\Prominence II [RPG] 2.8.4.mrpack" to "c:\\MCServers\\mc" File path is not safe: c:\MCServers\mc\mods\do-a-barrel-roll-3.3.7+1.20-fabric.jar

Nothing is created at all so it seems to be failing in the first step

Because the path format is different, additional processing may be required
Such as:\ and /

When installing a pack with Quilt, the command java -jar quilt-installer-latest.jar ... has an exit code to 1 : the jar file is corrupted.

After looking in the code, the link to download the quilt universal installer is not working (error 404).

To fix this, I think we must just change the https://maven.quiltmc.org/repository/release/org/quiltmc/quilt-installer/latest/quilt-installer-latest.jar to https://maven.quiltmc.org/repository/release/org/quiltmc/quilt-installer/0.5.0/quilt-installer-0.5.0.jar.

I'll do a PR to fix this.

As seen in #15.

For practical use, would it not be more convenient to integrate the start-server directly into the program。It will allow you to run on more systems

I've ran the forge installer with --installServer in my server dir (cl5)

If I run this command:

mrpack-install https://cdn.modrinth.com/data/VUmd23oG/versions/OB9wIUXt/Create%20Live%205%201.0.0.mrpack --server-dir cl5 --server-file cl5/libraries/net/minecraftforge/forge/1.20.1-47.2.0/forge-1.20.1-47.2.0-server.jar

I still get this:

Why does it create a .mrpack file when all I ask is server files? Like how can I go on forge and it has a .zip of server files for pretty much all modpacks, but that's not possible with mrpack-install?

Is there a way to actually get the files for this so that all I have to do is cd into the minecraft server directory and do ./run.sh?

Local cache for downloads with lookup based on some file hashing algo.

Use xdg for path lookup.
