    nwad

    Read/write WAD files, as used by Doom et al.

    npm install nwad

    Usage

    NB: All this module does is read from and write to the WAD data structure - reading or creating the appropriate file header, indices etc. A WAD is just a packed collection of "lumps" - to actually do anything interesting with the WAD you will need to work with these lumps - nlump is underway, this module serves as a base for that one.

    nwad.load

    Takes a Uint8Array and returns a WAD data structure:

    {
      "type": "", //"IWAD" or "PWAD"
      "lumps": [] //an array of lumps, as below
    }

    The lump structure:

    {
      "name": "",  //name as per the WAD info table
      "data": [] //a Uint8Array containing the lump data
    }

    Example:

    const fs = require( 'fs' )
    const nwad = require( 'nwad' )
     
    fs.readFile( 'doom.wad', ( err, buffer ) => {
      if( err ) throw err
     
      const wad = nwad.load( buffer )
     
      console.log( wad.type, wad.lumps.length )
    })

    nwad.save

    Takes a WAD data structure (as above) and returns a buffer:

    const fs = require( 'fs' )
    const nwad = require( 'nwad' )
    const getLumps = require( './some-module-for-getting-lumps-from-somewhere' )
     
    const wadBuffer = nwad.save({
      type: 'PWAD',
      lumps: getLumps()
    })
     
    fs.writeFile( 'my.wad', wadBuffer, err => {
      if( err ) throw err
    })
