How use tags saved in savedVariable?

[zork]

I'm currently writing an ingame config for oUF_Diablo.

I set up 2 dropdown menus a user can choose tags from.

--health tag list for dropdown
  db.list.health_tag = {
    { value = "[diablo:healthorbtop]",  key = "oUF_Diablo top default", },
    { value = "[diablo:healthorbbottom]",  key = "oUF_Diablo bottom default", },
    { value = "[perhp]",  key = "Health Percent", },
    { value = "[perhp]%",  key = "Health percent + %", },
    { value = "[curhp]",  key = "Current health", },
    { value = "[diablo:curhpshort]",  key = "Current health short", },
    { value = "[maxhp]",  key = "Max health", },
    { value = "[diablo:maxhpshort]",  key = "Max health short", },
    { value = "[curhp]/[maxhp]",  key = "Current/Max health", },
    { value = "[diablo:curhpshort]/[diablo:maxhpshort]",  key = "Current/Max health short", },
    { value = "[diablo:empty]",  key = "Empty", },
  }
  db.getListHealthTag = function() return db.list.health_tag end
 
  ---------------------------------------------
  --LIST / POWER TAGs
  ---------------------------------------------
 
  --power tag list for dropdown
  db.list.power_tag = {
    { value = "[diablo:powerorbtop]",  key = "oUF_Diablo top default", },
    { value = "[diablo:powerorbbottom]",  key = "oUF_Diablo bottom default", },
    { value = "[perpp]",  key = "Power Percent", },
    { value = "[perpp]%",  key = "Power percent + %", },
    { value = "[curpp]",  key = "Current power", },
    { value = "[diablo:curppshort]",  key = "Current power short", },
    { value = "[maxpp]",  key = "Max power", },
    { value = "[diablo:maxppshort]",  key = "Max power short", },
    { value = "[curpp]/[maxpp]",  key = "Current/Max power", },
    { value = "[diablo:curppshort]/[diablo:maxppshort]",  key = "Current/Max power short", },
    { value = "[diablo:empty]",  key = "Empty", },
  }
  db.getListPowerTag = function() return db.list.power_tag end

Currently I initiate my unitframes right on code execution.

I add the tag via:

self:Tag(fontString, tagName)

The problem that occured is the following.

I cannot "reset" the tag later on (on "VARIABLES_LOADED" event) to another tag. Or atleast I do not know how. Because I tried and it did not work.

Basically I initialize my unitframe with a default tag and rewrite it later if the savedVariables are loaded to the database values. Well that is my plan that I fail to succeed.

How do you handle unit tag initilization, especially with tags only available later on?

Actually I did not plan to suppress unit initilization until the database is loaded. Currently I run it with default values and have view functions that update stuff later on when needed.

Can I not add a tag on unitframe init and just add it once on VARIABLES_LOADED? That would be enough for my needs.

*edit*

Hmm...I think I have an idea. Why should I change the tag if I can change how the tag function reacts.

This may work out:

---------------------------------------------
 
  --HealthOrbTop
  oUF.Tags.Methods["diablo:HealthOrbTop"] = function(unit)
    local methodName = db.char["HEALTH"].value.top.tag
    return oUF.Tags.Methods[methodName](unit) or ""
  end
  oUF.Tags.Events["diablo:HealthOrbTop"] = "UNIT_HEALTH UNIT_MAXHEALTH UNIT_CONNECTION"
  
  ---------------------------------------------
 
  --HealthOrbBottom
  oUF.Tags.Methods["diablo:HealthOrbBottom"] = function(unit)
    local methodName = db.char["HEALTH"].value.bottom.tag
    return oUF.Tags.Methods[methodName](unit) or ""
  end
  oUF.Tags.Events["diablo:HealthOrbBottom"] = "UNIT_HEALTH UNIT_MAXHEALTH UNIT_CONNECTION"
 
  ---------------------------------------------
 
  --PowerOrbTop
  oUF.Tags.Methods["diablo:PowerOrbTop"] = function(unit)
    local methodName = db.char["POWER"].value.top.tag
    return oUF.Tags.Methods[methodName](unit) or ""
  end
  oUF.Tags.Events["diablo:PowerOrbTop"] = "UNIT_DISPLAYPOWER UNIT_POWER UNIT_MAXPOWER UNIT_CONNECTION"
  
 
  ---------------------------------------------
 
  --PowerOrbBottom
  oUF.Tags.Methods["diablo:PowerOrbBottom"] = function(unit)
    local methodName = db.char["POWER"].value.bottom.tag
    return oUF.Tags.Methods[methodName](unit) or ""
  end
  oUF.Tags.Events["diablo:PowerOrbBottom"] = "UNIT_DISPLAYPOWER UNIT_POWER UNIT_MAXPOWER UNIT_CONNECTION"
  
  ---------------------------------------------

Basically on my orbs I have 2 value strings each. Thus I run 4 tags. Each of those tags can be set to any methodName. The choosen method is then loaded on tag update by itself.

Going to test it later.

You should be using ADDON_LOADED and watching for your AddOn, as VARIABLES_LOADED is non-AddOn-specific.

Also, in addition to oUF's self:Tag(fontstring, tag) method, there is also a self:Untag(fontstring) method, so if you can't wait until your saved variables are loaded to initialize your frames, just untag the fontstring and re-tag it with the saved info.

Thanks Phanx. I tried Untagging. Didn't work for me. The idea I had worked out though.

If Untag doesn't work, you should probably report it to Haste so he can fix it.
