X-Perl UnitFrames

This project has become inactive.

This project is inactive and its default file will likely not work with the most recent version of World of Warcraft. The author may have abandoned it, or it may have outlived its usefulness.

Main Frames

Patch 6.0.3 compatibility and future of X-Perl

Use latest alpha from WoWAce for using in Patch 6.0.3


May still has problems but for most cases it should be working(at least was tested on beta), if not, clearing old setting by killing(and backup) XPerlxxxxxxx.lua in the WTF directory of your WoW installlation and try again with fresh new default setting, thanks your patience.

If still someone want to help Zeksie for he earns his donates from X-Perl then that's fine for Zek and X-Perl, but seems like it's time to cut him out as no one want to help X-Perl anymore (as many of users already heard about the mess of this poor addon), I guess.

I don't know X-Perl will still be continue or not(it's highly possible it won't be, as the new maintainer Resike continued the developing and forked to Z-Perl, and he said he won't abandon his addons), I won't force everyone should must to use Resike's one at this point, as his Z-Perl isn't stable yet, and for some reasons, I don't think he want to port his fixes back to X-Perl as he knows about how Zek did about his addons and everyone who helped Zek to maintaining this poor addon...and, of course...X-Perl may broken again when next time Blizzard's patches released..... /sigh

(At this point, I won't force everyone who used X-Perl to go Z-Perl until it's more stable than now, feel free to use Z-Perl or other Unitframe addons if you want, and do NOT hold your breathe about X-Perl too much, too. I already lost my hope on X-Perl, at least I can trust Resike and Z-Perl now...)


PlayerLin - Maintainer of X-Perl but not a proper skilled coder, just a locale translator and do some shitty PRs. :(

Bug Reporting

Please use the Ticketing System on WoWAce Here and avoid posting bugs using comments on Curse because they're difficult to track and they will probably get lost.

Use a good error catcher (like BugSack from files.wowace.com) and provide the full error text, and give as much information as possible to recreate the problem. Don't assume We know what you're talking about with some three word report.


Perl, with Extra stuff. Much enchanced from Nymbia's Perl UnitFrames, and a complete replacement for Blizzard's default unit frames, including raid frames and raid tools, with little remaining of the original Nymbia code.

  • Range Finder (combined with optional health check and/or debuff check) for all frames based on spell or item range test.
  • HoT Monitor will highlight units clearly that have ''your own'' active Heal over Time spells. Regardless of how many other heal over time buffs are on the raid members, you can keep track of your own ones and when they expire.
  • Debuff Highlighting in standard debuff colours on all friendly frames. Priority given to show debuffs that ''you'' can cure first.
  • Raid Frames, buff icons, MT list units and some other portions or X-Perl are Created on demand. Saving a lot of time and memory at system startup. Defering the creation of many parts of X-Perl to when they are actually required. And of course, most often outside of raids they are never required and are never created.
  • Raid Target icon support for Target, Target's Target, MT Targets.
  • Raid Tooltip will show combat rezzers available (druids with Rebirth ready (or very soon available) and any normal rezzers out of combat) if you bring up tooltip of a dead person.
  • In-combat indicators for all units.
  • 3D Portraits for player, pet, target, focus, party. Optional. Of course this may degrade your framerate somewhat because you are displaying more 3D character models that without this option. But some like it pretty, and it does look cool.
  • Red and Green combat flashes for frames when player, pet, target, party, partypets, raid take damage/heals. Useful indication of things happening.
  • Added '''time left''' on party member/target buffs/debuffs when in a raid, these depend somewhat on CTRA sending appropriate information over the addon channel, although some of it can be determined at run time by X-Perl, when a player gets a buff for example, we know how long it should last, and therefor when it should expire.
  • Totally new options window including all X-Perl options and access via minimap icon and the /xperl splash command.
  • Configurable colours for borders and backgrounds. Including class coloured names, and configurable reaction colours.

Much care has been taken with code size, memory load, memory usage per cycle and so on. LuaProfiler/OnEvent mods used extensively and regularly to ensure that X-Perl does not do more work than is absolutely necessary.

Assists View

Will show anyone from raid assising you with your target, and can also show healers or all plus known enemies targetting you.

Tooltips for the same also available (on player and target frames) if you prefer to not use the main window.

MT Targets

Replaces CTRA MT Targets window, and doubles as a replacement for the Perl RaidFrames warrior targets.

Indicator shows which target you are on.

Frames will be coloured to show if tanks have duplicate targets.

Casting Monitor


Shows selected classes (defaults to healer classes) in a list (much like the MT List), but with some differences.

Shows mana bars and cast bars on left. Their targets on right. Health bar as normal, but a secondary small red bar on targets which shows the maximum single hit this unit has received since entering combat. The secondary bar will extend downwards from their current HP level down to as far as zero.

A green name on the targets indicates this is the same target that you have. You can click on casters or their targets as expected.

For druids, right clicking on a caster will cast Innervate on them.

For shamans, right clicking on a caster will cast Mana Tide Totem. Check the * indicator to see if they're in your group.

All bars can be re-sized in X-Perl main options (Monitor section).

Totals can be toggled (from the 'T' minibutton at top of frame) which gives overview of raid mana status.

Raid Admin


Save/Load raid roster setups Only does direct save and load for the moment, but more to come (templates and such).

Item Check

Replacement for /raitem /radur /raresist /rareg. Use the old commands before, or drop items in the left item list.

Query button will perform /raitem on all ticked items (query always includes dur and resists) and you can then view and review all the results whenever, without having to re-query each item.

Includes everyone in raid, so you don't have to work out who doesn't have items, it'll list them with 0 instead of no entry.

Active Scanner to check raid member's equipment for the item selected. So you can be sure that people actually have the item worn (Onyxia Cloak for example), without having to go round single target inspecting everyone who 'forgot' to install CTRA for the 50th raid in a row.

Grim Reaper

Removed from X-Perl, but continues as it's own standalone Ace mod.


More Buffing Features

Can be found in my new universal buffing mod, ZOMGBuffs

    That lua error is caused by trying to set values before settings are even loaded, there was a REASON some things were called after variables loaded.

    I'm going to have someone look over the changes and refix them when they have time. I have no clue where to start in fixing it. Aside from reverting it all. Even if deleting config files fixes it, that's simply not an option, the proper way to do an update that affects config is to write in code to convert incompatabile config to new config. also error doesn't occur on reload UI only on player login, which leads me to suspect the only problem is a function is being called too early for login but it doesn't affect reloadui.

    OK, looks like Sontix's fixes working fine (at least) in my end and only one LUA error about conf when every time login.

    But I can't find any broken-age in X-Perl so I guess this is OK?

    Last time I checked in 4.0 launches, it should be player frame, buffs overlapping on player frame itself and it's looking funny, I don't know it did that in 3.x and older but I think it's not normal.

    EDIT: Checked ingame, the buffs on above of frame did funny shit when my buffs have 2 lines or more, it give me a line of empty between the frame and buffs lines, but not overlapping on player frame anymore. Target frame do nothing when I checked the "buffs on above", its buffs still display on under of frame. ToT one works fine at all...

    For "many functions are copied in every module" one, I guess it may due you can disable some X-Perl module...
    Like I sometimes just disable all X-Perl Raid module addons and X-Perl still working fine, but I don't know if this make sense or...

    buffs above frame

    On which frame? player or target?

    I have them working on player (above and below) and the only bug i see on the target frame is that sometimes if you have big debuffs enabled some debuffs overlap the big one (and i haven't fixed that yet)

    I haven't changed too much to the raid frame, my role icons are working the right way, i've heard that in the official version there problems when you change position to the players with the wrong role icon being displayed.

    I'd like to make it look like voodho or make the custom highlight look like a debuff icon with stacks, timer etc

    I still don't get why many functions are copied in every module or why there are huge _init functions that also update the frames etc. If i could get the animation around dispellable debuffs and the xperl skin in another better organized frame like ouf i'd change to it in no time :P

    we have no idea what MoP does to it yet, they haven't enabled mods. but it's likley it will break a ton of stuff.

    Actually, NOT every files, many directories of X-Perl that got changed in your modified r629 package just a TOC file modified due......stupid WoWAce/Curse Packager adding the X-Curse-blahblah shit after someone commit the change to SVN repo so they don't count if you ask me, and options UI, many localization files also not changed. Yes, it's pointless and fxxxing stupid to care them but I just care when you say something like "I changed many files of X-Perl", I'm sorry but I just cannot resist. :\
    (You didn't changing any X-Perl_Raidxxxxxx files except XPerl_Raid.lua, right? :P)

    OK, I don't know that's your version and it doesn't compatible with official one. Just my fault.
    Here is the patch based on the one that based on official r629.
    (And will find some time to check them in game again...)

    If Mysticalos did not want give a shit about make X-Perl working on MoP then whatever, maybe someone want to do, maybe.
    And...the worst case still X-Perl just die in a shit and no one cares to fix it anymore. I don't care. :\

    What needed fixed in MoP, I guess when MoP beta can using 3rd-party addons and you'll know.
    But now, many X-Perl functions or features was worked then broken on patch 4.x like X-Perl info on guildmates and buffs above frame still no one can fix, maybe you can try them?

    Rewritten? Personally, I guess unless you really get what Zek was did on his code and get it, else it's just hard.

    @Sontix : I checked your changes and made a patch file for it, but for some reasons, I see a lot of other changes, so I don't want just push it right now.
    (It already on my current xperl checkout directory but I don't want push to commit without some checks by other or something. :3)
    And I still testing those changes with my end...

    This is a TortoiseSVN patch file for all of Sontix's fixes.
    (Yes, I did some pointless comment changes but actual code do not changed at all!)

    Also, attaching all other unchanged files to finding actual changes is STILL pain in my ass. :p

    EDIT : Ok, I guess I needed a change list for your fixes, sontix...(I know you did on sometime but I just lazy to find it out again...) :\

    EDIT 2 : Shit, your specialbar fixes do not work when I log on my Paladin, throw LUA errors to me.

    The id 3 one appears when try to attacking enemy and get Holy Power...it's not appears anymore, I guess because error id 1 and 2 said specialbar is a nil value.

    @sontix: I'll download your fix and try using that for a while and see does it works or still not...I guess it needed take some time to make sure......but...that stupid uploading.com refuse let me download it again after I click to cancel for some reasons...maybe try it again tomorrow... :\

    Zek...never heard him again for a long time, very very long time... (Last time we talking about X-Perl was 1 year and 2 months ago...guess the Real-Life(TM) got him down or he just tried about WoW or X-Perl broken-age...or maybe mysticalos knows...)

    Reverted the aura's change. unitaura fails quite consistently. I don't think the API is as fast or has some kind of throttle cause in 25 man raids it isn't trigger crap. I haven't seen a working custom highlight since trying to use UnitAura instead of UnitDebuff api. So i reverted it back to UnitDebuff, that means flag carrior "buff" won't work again, but that's no real loss, that's like the only debuff in game that's flagged improperly, people will live.
