This project is an alternative to the Slipstream Mod Manager, written in Rust and with some additional features.

• Regular FTL mods (mostly Slipstream compatible*)
• Automatic Hyperspace installer

Currently automatic hyperspace installation is only supported on the following OS + Store combinations:

• Windows + Steam
• Linux + Steam

Adding support for other game stores is possible, but I only own the game on Steam so I have no way of testing potential implementations. If anyone wants an implementation and is willing to test changes for me, open an issue.

* Most Slipstream mods are supported but these Slipstream features are currently unimplemented:

• .rawappend.xml/.xml.rawappend files
• .rawclobber.xml/.xml.rawclobber files
• Some ill-formed XML files may still be rejected by ftlman but accepted by Slipstream.

These features are not particularly difficult to implement but I just don't have any mods that actually use these features so I can't test them. If you find a mod that requires this please open an issue.

If you a mod that fails to patch with ftlman but works with slipstream or one that works different under ftlman also open an issue.

Pre-built binaries for both Linux and Windows are available in the Releases tab.

Compilation requires a nightly Rust toolchain due to questionable design decisions I made in silpkg. For instructions on installing Rust go to https://www.rust-lang.org/tools/install, make sure to select the nightly toolchain release during installation.

After installing Rust, open a terminal then execute the following command:

cargo install --git https://github.com/afishhh/ftlman

You should then be able to run ftlman in a terminal to start the program.

Add this repository to your flake inputs and then use the default package output.

{
  # ... other inputs ...
  inputs.ftlman.url = "github:afishhh/ftlman";
  # Optionally reuse top-level nixpkgs
  # inputs.ftlman.inputs.nixpkgs.follows = "nixpkgs";

  outputs = { self, ftlman, ... }:
    let
      package = ftlman.packages.${system}.default;
    in {
      # use package
    };
}

You can also try out the program using nix run:

nix run github:afishhh/ftlman
