This project is mostly aimed at generating large Crusader Kings 2 modpacks for private use. The patcher reads the settings.txt file of the game and uses those mods as the list to determine mod conflicts and what mod content to package. By default, the patcher will only generate a mod that contains the files which conflicted and an accompanying .mod description file that lists its dependencies to ensure load order.

These patches seem to work for most mods, but run into issues specifically with overhaul mods, or other mods which conflict in the same files as their specified replacement paths.

Using the extract flag is recommended, as it ensures that every person using the modpack has identical data and only needs to enable a single mod.

The current state of the project is experimental at best. Requires rust's cargo/rustup to compile.

Install cargo and clone the repository.

cd /path/to/repository
cargo build --release --features command-line --bin merger-cli

Requires the GTK-3 dev libraries for your OS or distribution.

On Arch:

# pacman -S gtk3

On Ubuntu:

# apt install libgtk-3-dev

On Windows:

Install the gtk3 libraries using MSYS2

After installing the dependencies run cargo using the following flags.

and then build using:

cargo build --release --features gui-interface --bin merger-gui
