It looks like the format of the link strings for tradeskills has changed... I'll dig in; almost for sure the exact same issue in lots of other addons too.

I am getting this error too. Thank you for looking into it!

The format of a TradeSkillLink has changed. Someone posted a link on the main page to this page, which shows the difference:

http://www.wowpedia.org/TradeSkillLink

Same :(

I'm also getting this error, but only the first time I load. (Gnomeworks doesn't start working afterward, just doesn't give me the error message)

Looking at this briefly last night, it seemed like GetSpellLink() wasn't giving any tradeskill info in the trade link, just a "bare" link with the trade's name in it, colorized.

This:

http://www.wowpedia.org/TradeSkillLink

says that you can get the link from GetTradeSkillListLink() which returns a new format of the link, but only for the "currently open" tradeskill, which sucks mightily... Hopefully I'm just wrong about the failure of GetSpellLink – it was returning , but they both seemed to not contain the detailed skill data.

Never mind, I'm an idiot – was just printing wrong and so it was hiding the extra data because it was pretty-printing the link...

from just a quick glance, it looks like the GUID is now the first field in the link and the trade id is the second field.

looking at cooking, tho, is rather daunting... seems to have all the sub classes listed as individual fields with thier own levels and bitmaps.

sadly, they still don't give smelting links.  no clue why they treat mining/smelting different from other trade skills.  my gut says it was an oversight based on the names of the skills ("smelting" is the name you get in your window, but your profession is "mining") but that oversight has become gospel.

it would probably be good to push all the link parsing to a single function so it could be more easily modified.  something that would return the pertinent pieces in a defined order that won't change.

edit: looks like the wiki updated with the cooking example.  do the cooking links show the specializations even if you only have level 1 cooking?

@lilsparky: Go

Yeah, I was taking a look. Basically, instead of one skill:current:max:bitfield it's now a series of them (at least for cooking), and the GUID moved out-of-line. I haven't looked to see if they do something similar to cooking for goblin vs gnome engineering... Needs some changes to all the parsing code, at least for cooking, it's not a few-line change to fix the regexes sadly.

something like

guid,skills,name =
     string.match(tradeLink,
        "|cffffd000|Htrade:([0-9a-fA-F]+)([^|]+)|h%[([^]]+)%]|h|r")
repeat
  skill,current,max,bitmap,skills =
        string.match(skills,
           ":(%d+):(%d+):(%d+):([0-9a-zA-Z+/]+)(.*)")
   parse(bitmap)
until not skills

@hughescr: Go

i think it's just cooking that has this weird stuff, but i would anticipate that other skills might end up with it.

your code really illustrates why they moved the guid to the start - it makes nice quads of tradeID, rank, maxRank, bitmap.

that makes me think a generic parsing function could return the "basic" level stuff and then an additional table for the subskills (or nil if there are none). that's probably more useful than returning a table all the time with index 1 being the base skill info given the likely usage. if i was more hip to metatables, it'd probably be worth keeping the resuls around with the link as the metatable key.

this also means my hacky level code for local cooking can be removed.

i'm hopeful of some way to discover the names associated with the sub-skill id's via the game client. i suppose maybe worst case we link the subskill id's to the official "way" spells. like: id[975] = 125589 - not sure that's the right one, but tha'ts the idea.

@lilsparky: Go

IMO metatable shenanigans aren't worth it. We do a lot of Lua coding at work, and I'm constantly trying to get the smarter/more clever devs to stop using fancy Lua metatable features, because it makes their code a lot less readable for other people who might need to interact with it. Better to keep things slightly less fancy but more readable/maintenable but other people.
