factorio-hs

Very early and experimental library for working with Factorio data. Assume it doesn't work. The solver is intended to be a port of Foreman, but is a long way from being so. It should be platform agnostic, but I've only tried it on Ubuntu.

All command line tools will require an existing Factorio installation:

export FACTORIO_PATH=/opt/factorio

factorio-recipes is a debug tool that prints all loaded recipes. It can be a quick way to find recipe names for constructing graphs.

$ factorio-recipes $FACTORIO_PATH | grep rocket
Recipe {name = "rocket-part", items = [Ingredient "low-density-structure" (-10.0),Ingredient "rocket-fuel" (-10.0),Ingredient "rocket-control-unit" (-10.0),Ingredient "rocket-part" 1.0], category = "rocket-building"}

factorio-solve takes a graphviz representation of an assembly line and annotates it with perfect ratio data:

$ cat example.dot
digraph {
  "copper-cable"
  "copper-plate"
  "iron-plate"
  "electronic-circuit" [factorioTarget = 10]

  "iron-plate" -> "electronic-circuit";
  "copper-plate" -> "copper-cable" -> "electronic-circuit";
}
$ factorio-solve $FACTORIO_PATH example.dot
digraph {
    "copper-cable" [factorioRate=15.0];
    "copper-plate" [factorioRate=15.0];
    "iron-plate" [factorioRate=10.0];
    "electronic-circuit" [factorioRate=10.0
                         ,factorioTarget=10];
    "iron-plate" -> "electronic-circuit";
    "copper-plate" -> "copper-cable";
    "copper-cable" -> "electronic-circuit";
}

This tells us that to run the electronic-circuit recipe 10 times, we need to run the copper-cable recipe 15 times (which actually generates 30 cable).

Installation

None provided yet. Please follow the development instructions.

Development

Some one time setup is needed to install GLPK and Stack. For Ubuntu something like:

sudo apt-get install libglpk-dev haskell-stack
stack upgrade

You can then use standard stack commands to run the programs:

stack build && stack exec factorio-solve $FACTORIO_PATH example.dot

Wishlist

• Arbitrary supply/consume/passthrough nodes.
• Show assembler/module needs.
• Calculate power usage.
• Auto graph generation (so you don't need to map a rocket build out by hand...)
• Better frontend than graphviz.
• Test coverage.
