This mod manager is made a protect the game files & mods files at all costs. if an operation or a mod tries to modify the files they will be stocked in and overlay folder (~/.local/share/modmanager/UPPER_DIRS/appid)

this mod manager will try to enable casefold inside the mods folder as a way of ensuring that there will not be two file with the same name.

mods conflicts are solved by priority, currently we still have to implements a way to change the priority.

Use --list-games or -l to list compatible games
Use --add or -a <APPID> <FILENAME> to add a mod to a game
Use --list-mods or -m <APPID> to list all mods for a game
Use --install or -i <APPID> <MODID> to add a mod to a game
Use --remove or -r <APPID> <MODID> to remove a mod from a game
Use --deploy or -d <APPID> to deploy the mods for the game
Use --unbind or -u <APPID> to rollback a deployment
Use --fomod <APPID> <MODID> to create a new mod using the result from the FOMod

Requirements:

glib2

Optional requirements:

Fuse (2 or 3)
Fuse-overlayfs

instructions and warnings about casefold:

Casefold is and options in some linux filesystem that will make a folder (not the whole filesystem) case insensitive, this is really good for proton since it gives a small lookup performance boost and allow us to install mods without fearing having two file with the same name.

sadly i don't think overlayfs support it, but it might still be worth a try. currently i haven't tested without casefold and mods might break because of that.

TODO:

we need a name for this.
allow to change mod priority.
add more game to the code, currently i only have Skyrim se.
replace the copy of the games files by hard links if available.
try alternatives to overlayfs (searching for casefold support)
adding a hook for %command% in steam

How to contribute:

if you have creation engine based games not listed in src/steam.h please open an issue with the EXACT name of the game folder in steamapps/common/

otherwise if you know how to code in c don't be scared to create mr or suggest changes.

don't try to make me change the licence i chose GPL-2 on purpose and i won't use GPL-3.

Compilation and install instructions:

download a version from the releases(please avoir a simple clone of the git).
