Omgifol is a Python library for WAD files. It is open source software originally written by Fredrik Johansson and currently maintained by Devin Acker (Revenant), and is released under the terms of the MIT License. The most recent version, 0.4.0, was released February 22, 2018.
In September 2015 Fredrik confirmed that the original library was no longer being maintained, and recommended to use a more actively maintained fork by Revenant. In November of the same year, this fork was given Fredrik's blessing to become the basis of a new release, and nearly two years later it was finally published to the Python Package Index as version 0.3.0.
As of version 0.3.0, the library aims for out-of-the-box compatibility with both Python 2.7 and Python 3.
- Basic lump management (copying, moving, renaming, saving to files, etc)
- Editing the following special lumps: COLORMAP, PLAYPAL, TEXTURE1/PNAMES
- Saving/loading most common image and sound formats
- Editing maps
- Encoding/decoding linedef types (including Boom types)
mirror.py, a demo script that mirrors maps in a WAD, which is included in the 0.2 release:
from sys import argv from omg import * from omg.mapedit import * def mirror(map): ed = MapEditor(map) for v in ed.vertexes: v.x = -v.x for l in ed.linedefs: l.vx_a, l.vx_b = l.vx_b, l.vx_a for t in ed.things: t.x = -t.x t.angle = (180 - t.angle) % 360 ed.nodes.data = "" return ed.to_lumps() def main(args): if (len(args) < 2): print " Omgifol script: mirror maps\n" print " Usage:" print " mirror.py input.wad output.wad [pattern]\n" print " Mirror all maps or those whose name match the given pattern" print " (eg E?M4 or MAP*)." print " Note: nodes will have to be rebuilt externally.\n" else: print "Loading %s..." % args inwad = WAD() outwad = WAD() inwad.from_file(args) pattern = "*" if (len(args) == 3): pattern = args for name in inwad.maps.find(pattern): print "Mirroring %s" % name outwad.maps[name] = mirror(inwad.maps[name]) print "Saving %s..." % args outwad.to_file(args) if __name__ == "__main__": main(argv[1:])
Another included demo script is drawmaps.py to save map preview images. This script is one of the tools most suitable for creating map views on Doom Wiki. After the initial v0.2 release, Fredrik made further improvements to its handling of the specified image dimensions.
In April 2016, Frans P. de Vries added support for a scale parameter that is applied to all requested map images, and for optional verbose logging. The following example command renders all DOOM2.WAD maps at the same scale (with only the largest maps sized down to fit within 1600 pixels) so the viewer gets a good impression of the size differences between them:
python drawmaps.py DOOM2.WAD MAP* 1600 4.0
A subsequent addition in September/October 2018 was to optionally render numbered spawn points for deathmatch starts (in green) and Capture the Flag/Capture the Chalice starts (in blue and red), allowing such map views to illustrate multiplayer map analysis and tactics.
"OMGIFOL" stands for "Oh My God! It's Full Of Lumps!"
