Semi-automatically change talents

[Malsomnus]

I'm working on an add-on that will remind people to change their talents before specific boss fights (by their personal choice, of course). Is there a way to automate any part of the talent switching process?
(The holy grail here would be creating a button that says Click Here To Learn These 4 Talents, but I've been unable to find a way to do that)

Ro posted a talent-swapping macro here, but apparently it's not always reliable when trying to switch multiple talent tiers at once.

You could use a secure action button with type = macro and dynamically build up a macro for each tier you need to swap.

Hmmm... that thread implies that it's possible to switch one talent with an add-on, but doesn't say how. Does it mean the way to do this via add-on is, as you said, to make a secure button which creates and calls that sort of talent swapping macro?

Also I'm starting to think it might be best to not fully automate it anyway, but to list the talents that you presumably want to learn and put a button next to each.

should be possible:

have a look at the last 3 there.

None of these functions are usable from add-ons, or even from macros :/

[Edit]
And while I'm at it, how can I open the talents frame programmatically?

You can call LearnTalents, you don't even need a hardware event for it.
All the issues are from RemoveTalent, which is not only locked to hardware events, but can only be called from blizzard code.
The only calls to the function and made in the StaticPopup handlers in Blizzard_TalentUI.lua, trigged in PlayerTalentFrameTalent_OnClick, only called by the OnClick handler for PlayerTalentButtonTemplate in Blizzard_TalentUI.xml.
The talent UI needs to be loaded though a hardware event to avoid taint, the easiest way to do that is to toggle the frame though a double /click TalentMicroButton.

Eventually you'll end up with something like this:

/stopmacro [combat]
/click TalentMicroButton
/click TalentMicroButton
/click PlayerTalentFrameTalentsTalentRowXTalentY -- talent you want to learn (row/col)
/click StaticPopup1Button1 -- should probaly had some checking for which popup is actually the talent one.
/click PlayerTalentFrameTalentsTalentRowXTalentY -- repeat as needed....
/click StaticPopup1Button1
...
/run LearnTalents(a,b,c,d,e,...) -- will need to be a slightly delayed call to give the server time to process the unlearns

I explained in the other thread that the game generally won't let you unlearn multiple talents at once, you will get "another action is in progress" error if you try to make one large macro like that.

Occasionally it does let you swap more than one at a time, the problem is that since it's completely inconsistent you can't rely on it correctly changing out your talents.

Thought cause it is flagged as noncombat and not as protected it works, but while removetalent is protected learntalents is not, just tested that.

You could probably dispatch the LearnTalents() call to a C_Timer.After() function.

/run C_Timer.After(1,function() LearnTalents(a,b,c,d,e,...) end)

The first argument to C_Timer.After() is how many seconds to delay running the function defined as the second argument.
