deduplicate steam card online tool [beta]

halloween update : it seems the script is not working anymore since a few days. I will fix that soon and improve it ^_^

Read me:

So, i just wrote this script: Steam Card Deduplicator that will generate this kind of result.
It's like steamcardexchange.net but directly from friend to friend (no bot).

How it works :

• 1: You pick two steam users, let's say A is on left, B on right then you press « deduplicate », this will load and compare every game cards of A and B, and will automatically match cards ( middle of screen ) to trade between A and B ( 1v1 in same set of card only) in such a way both will have less duplicates at the end ( never more ).
• 2: A and B do a steam trade and just follow their « give » column.

This is BETA, so please be constructive in your comments ^_^

Optional read :

When you look at the « give » columns, there are 3 possible situations :

• A and B have both duplicates they don't have each others=> mutual benefits.
• A have duplicate that B don't have, B swap any card => B is helping A. ( B can say « hey, i have nothing to win in this situation! », well, the look at the last case then… ).
• B have duplicate that A don't have, A swap any card => A is helping B.

You can use a direct link to post in chat : example (change the left and right parameters).

If you are curious or want to help, just look at source code, yeah just a plain html and javascript.

I made this to have a faster way to compare cards with friends ( because looking in each steam card set to see who have cards i want and having to cross-compare inventories and do this for every game takes way too long ) so that i can just say « hey, let's deduplicate, just put the cards you see [link to site] in your trade window ».

I know there are currently a few « glitches » :

• sometimes it won't pick all the possible swap (you have to launch it again to see if you can do a second pass).
• it will work only with public profiles, and i don't know ( yet ) how to parse the cards that a user is selling ( cards must be in inventory to be compared ).
• tested with chrome and firefox. If you have some strict ad-block rules it may block steam cdn card pictures ( their url are strange ).
• there is no hidden goal in using this tool, the only downside i can think is « maybe » in some set, at a certain time, all the cards don't have the exact same value. If you have a concern about this you can just … not use this tool :D
• it may be a little confusing at first glance, help me to explain it in a shorter way if you can ( i will edit the « how it work » section ), thank you.
