npm install doom-wad
Tries to take a DOOM WAD (Heretic et al. not supported at present, PRs welcome) and mangle it into something useful.
Can handle most of the data used by DOOM and DOOM 2, see nlump for more details on which lumps are supported
It basically just uses nlump to convert the lumps, and tries to organise them meaningfully, eg. grouping map lumps together etc.
Known to work with DOOM and DOOM 2 IWADs, the handful of map-only PWADs I tried also worked
const fs = require( 'fs' )
const wad = require( 'doom-wad' )
fs.readFile( 'doom.wad', ( err, buffer ) => {
const data = wad( buffer )
console.dir( data )
})
