UI Lua API import (WAR 1.4.8)

New page

{{LuaApi|group=Time}}
Returns the name of a month in the language of the computer's regional settings.

<pre>
name = GetMonthName(monthIndex, abbreviated)
</pre>

== Arguments ==
;monthIndex : <code>number</code> – Month, 1 (January) to 12 (December). Fractions are dropped.
;abbreviated : <code>boolean</code> – <code>true</code> for the short form of the name, <code>false</code> for the full name.

== Returns ==
;name : <code>wstring</code> – The month name.

== Details ==
* The name comes from Windows' locale data for the current thread locale, not from the game's string tables.
* If Windows cannot supply the name, an empty string is returned.
* With a <code>monthIndex</code> outside 1–12 the client logs the ''Invalid month index'' error and returns nothing.
* <code>abbreviated</code> must be a real boolean. Passing <code>nil</code> or a number raises an ''Invalid Parameters'' error.
* The function needs at least two arguments and only reads the last two.
* The stock UI never calls <code>GetMonthName</code>.

== Errors ==
This is written to the UI log; the call returns normally.
* <code>Error in function call 'GetMonthName': Invalid month index.</code>

== Example ==
A minimal example built from the signature above:
<pre>
local fullName = GetMonthName( 3, false )
local shortName = GetMonthName( 3, true )
</pre>
