Finding out how many maps are in a zip

[Doomkid]

Let’s say you have a huge zip file or other archive full of WADs. Is there any way to determine how many actual maps are present? I’m just curious to count the sheer number of maps present in various different wad packs I have. Thank you in advance!

I ran into problems like that often, which is why I created wadcat. For a zip, you would need to unzip the files. Otherwise you just need:

 

1. A command to list all the files

2. A way to extract the MAPxx/ExMy header entries (under the assumption they are all valid, of course; this is what wadcat does).

3. A way to count the number of things extracted.

 

So in Unix/Linux, this would be:

$ find . -iname *.wad -print0 | xargs -0 -L1 -- wadcat -qm | wc -l
     174

find = find all the wad files in a folder hierarchy

xargs = pass them to wadcat

wc = count the number of printed lines in the output

 

In my case, I learned I have 174 maps in my "to play" folder. I guess I have a lot to do! :)

Thank you, JadingTsunami!

so you need Yet Another Utility? (winks)

@Doomkid here: CountMaps.

 

use like this:

countmap.exe *.zip >list.txt

 

it understands ".wad", ".zip", ".pk3" files. for zips, it will check if there are ".wad" or ".pk3" files inside, and check them. i.e. you don't need to unpack anything. enjoy. ;-)

 

p.s.: if wildcards don't work, ping me here, and i'll fix it (i am too used to shell wildcard expansion on *nix, and don't remember if MinGW runtime does it on Windows, or not).

Ketmar, I cannot thank you enough..!

 

EDIT: uh oh, I'm getting "k8vavoom fatal error: out of memory for 66528 bytes!"

[ketmar]

your zip is freakin' huge, right? ;-) currently, the program tries to load things in memory for speed. i'll take a look, and maybe will add a switch for slower mode.

[ketmar]

@Doomkid ok, try this one instead. it should be better (if i didn't messed the things yet again ;-).

[Doomkid]

You are so talented with Doom programs, Ketmar.. Thanks for using it to help me so many times now. Works like a charm!

 

Turns out, there's 8,589 maps in the Big Vanilla Wad Pack (though probably 200 or so are duplicates between Doom1 and 2, demo "map fragments" that come with DEU and such, yadda yadda..) but still, that's a whole hell of a lot of Doom!

great! no problems, i'm simply reusing k8vavoom code here (and found some small bugs there, so you prolly helped me more than i helped you ;-). glad it worked.

p.s.: if anybody's interested, the source is here. but it is using my own build tools, and k8vavoom core libraries, so it is prolly of no much use. yet GPL demands is, so here it is. ;-)
