SDE Patched

A patched EVE Online SDE to work better with EVEShipFit's dogma-engine.

The main goal is to produce a small data-file, with everything included for dogma-engine to calculate fit statistics.

Prerequisite

• Go 1.27 or later
• flatc

Usage

go run ./cmd/sde-patched download        # fetch the latest SDE into sde/
go run ./cmd/sde-patched build           # write dist/sde.dat and dist/names.dat
go run ./cmd/sde-patched compare old/    # tell whether dist/ differs from old/, ignoring the SDE build
go run ./cmd/sde-patched patches         # list all patches
go run ./cmd/sde-patched ids             # give an ID to anything added without one
go run ./cmd/sde-patched explain alignTime
go run ./cmd/sde-patched explain --type "Rifter"
go run ./cmd/sde-patched serve           # edit the patches in a browser

build downloads the SDE when there is none yet, and uses the one on disk otherwise. Use --build <number> to pin a version.

Editing

The patches are best edited via the web-editor (via serve). It allows for full customization of all existing and new attributes.

This editor is fully vibe-coded, and it is very likely no human actually understands how it works. It is also not meant as "production-ready" software, but much more as "an easier way to digest patches".

Output

build writes two flatbuffers, described in specs/:

• dist/sde.dat holds the types, dogma, groups, categories, buffs and mutaplasmids, with English names only. It is all a dogma-engine needs.
• dist/names.dat maps a name in any of the eight languages EVE supports back to a type ID. Only an EFT-fit importer needs it, and only ever to search.

npm

npm install @eveshipfit/sde

@eveshipfit/sde ships both files and the schemas, under dist/ and specs/.

Python

pip install eveshipfit-sde

eveshipfit-sde ships both files and the schemas, and the paths to them.

from eveshipfit_sde import build_number, names_path, sde_path, specs_path

dogma.load_sde_from_file(sde_path())

build_number() reads the SDE build straight off the version.

Releasing

Every day at 12:00 UTC, main is built against the latest SDE. When the result differs from the latest release, the SDE build number aside, a new release is made and published on npm and PyPI. A change to the patches is released this way too.

Patches

The SDE describes what the EVE client needs, not what a fitting tool needs. Align time, for example, is not an attribute; the client works it out. Patches add the missing attributes and effects, so a dogma-engine can work them out instead.
