EVEShip.fit's Dogma Engine for Python
This library calculates accurately statistics of an EVE Online ship fit.
The input are several data-files provided by EVE Online, together with a ship fit. The output are all the Dogma attributes of the ship, its items and the character.
The engine is written in Rust; this package wraps it, so every lookup happens inside Rust.
Install
The sde extra brings in eveshipfit-sde, which ships sde.dat.
pip install eveshipfit-dogma-engine[sde]
Usage
import esf_dogma_engine as dogma
from eveshipfit_sde import sde_path
build_number = dogma.load_sde_from_file(sde_path())
fit = {
"ship": {"type_id": 587},
"items": [
{
"type_id": 2873,
"slot": {"type": "high", "index": 0},
"state": "active",
"charge": {"type_id": 185},
}
],
"character": {"skills": {3300: 5}},
}
calculation = dogma.calculate(fit)
# Or if you want to know the source of the effects:
with_sources = dogma.calculate(fit, {"sources": True})
# Or if you have a beacon in space (like wormhole effects):
with_beacon = dogma.calculate({**fit, "incoming": dogma.beacon(beacon_type_id)})
# Or if you have an EFT, the text format EVE copies a fit to the clipboard in:
imported = dogma.calculate(dogma.load_eft("[Rifter, My Rifter]\n200mm AutoCannon I"))
# And to write a fit back out as EFT:
eft = dogma.save_eft(fit)
# What EVE would not let you fly, in `violations` of the calculation:
validated = dogma.calculate(fit, {"validate": True})
load_sde_from_file may only be called once per process.
An EFT import matches the English names in sde.dat.
To also match the other languages EVE supports, load names.dat as well:
from eveshipfit_sde import names_path
dogma.load_names_from_file(names_path())
Fits and calculations are plain dicts, typed with TypedDict in esf_dogma_engine.types.
What every field means is explained under Input and output.
load_eft, calculate and beacon release the GIL while they work, so a thread pool calculates fits in parallel.
