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

• Regular FTL mods (Slipstream compatible¹)
• Supports mod tags from Blizz's Slipstream fork
• Supports an ftlman-specific Lua patching API (documentation available here)
• Automatic Hyperspace installer
• Functional² XML and Lua Sandbox (syntax highlighting, WIP diagnostics)

Currently automatic hyperspace installation is supported for the following FTL versions:

• Steam (Linux and Windows)
• Epic (untested)
• Origin (untested)

Patching the Microsoft version is technically supported but you may encounter permission problems if you try to patch it in the original installation directory.

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

¹ ftlman's XML parser is modeled closely after FTL's (RapidXML). This means it is very lenient but behaviour may be slightly different than Slipstream, due to Slipstream's messy handling of sloppy parsing.
² Struggles with files hundreds of kilobytes in size.

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 --locked --git https://github.com/afishhh/ftlman 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
