Atlas Core
A library (currently only for configs) used by Atlas Development projects
Quick answer
Which Atlas Core release should I use?
Atlas Core 1.1.3-26.2-Fabric targets 26.2 with Fabric, Quilt. Installation on the client is optional. Installation on the dedicated server is optional. All 2 required mods have matching files.
Where it goes
Is Atlas Core required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does Atlas Core 1.1.3-26.2-Fabric need?
1.1.3-26.2-Fabric. Change the file and its required mods may change too.
Install Fabric API, Cloth Config API first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Atlas Core add?
Atlas Core
A mod library for Atlas Projects
A simple library that currently provides a command library and a robust config system, if admittedly incomplete.
However, it will be expanded to suit more needs as time progresses, and improvements to the config will be made.
Commands
As of right now, the command library consists of adding an argument type that allows you to use interchangeable arguments, as in, if certain arguments are not needed, then one can have the user specify the arguments provided with proper suggestions in the format <arg_name>=<arg_value>.
However, in the future the plan is to create a parameters argument which allows you to insert [--someArg value -someOtherArg], matching usual command line parameters, with suggestions for what to input.
In addition, eventually an easier way to achieve wanted results for vanilla argument types and ones which are added by Atlas Core when they are used as opts arguments.
Configs
By default, configs are stored in ./config/<mod_id>/<config_path>.json, which is where you will be able to access and edit them.
If the config has a GUI, it will appear in the Atlas Configs menu inside of Options on both pause screen and title screen. If Mod Menu is installed, the Atlas Configs menu appears as the config for Atlas Core. If a mod has an attached default config with a screen, it will become the config screen for that mod in Mod Menu.
Configs can also be read or manipulated using the command /atlas_config, which lets you reset, read, or reload configs all at once, reset, read, or reload a particular config, or edit, reset, or retrieve the value of a specific option.
