Native Lua statement: | |||
for [variable] = [lowvalue], [highvalue],[step] do [statements] end | |||
''' | Executes 'statements' for each value of 'variable' from 'lowvalue' to 'highvalue', at a step value of 'step' inclusive. Other syntax options yet unknown. | ||
Executes 'statements' for each | for [key],[value] in pairs([table]) do [statements] end | ||
Executes 'statements' for each element of the 'table'. 'key' contains element key (index), 'value' contains element value. | |||

Examples: | |||
/script for i=1,10 do DEFAULT_CHAT_FRAME:AddMessage(format("%d",i));end | /script for i=1,10 do DEFAULT_CHAT_FRAME:AddMessage(format("%d",i));end | ||

name,description,standingID,barValue,atWarWith,canToggleAtWar,isHeader,isCollapsed=GetFactionInfo(i); | name,description,standingID,barValue,atWarWith,canToggleAtWar,isHeader,isCollapsed=GetFactionInfo(i); | ||
DEFAULT_CHAT_FRAME:AddMessage(format("%s %d/%d,name,barValue*21000,21000)); | DEFAULT_CHAT_FRAME:AddMessage(format("%s %d/%d",name,barValue*21000,21000)); | ||
end | end | ||
A few examples using the newly found <step> value: | |||
/script for i=10,1,-1 do DEFAULT_CHAT_FRAME:AddMessage(format("%d",i));end | |||
Will count from 10 to 1. | |||
/script for i=10,0,-2 do DEFAULT_CHAT_FRAME:AddMessage(format("%d",i));end | |||
Will count from 10 to 0 skipping every other number. | |||
/script for i=2,10,2 do DEFAULT_CHAT_FRAME:AddMessage(format("%d",i));end | |||
Will count even numbers from 2 to 10. | |||
Examples for the 'in' version of the syntax: | |||
/script myTable = {"a","b","c","d"}; | |||
for k,v in pairs(myTable) do | |||
DEFAULT_CHAT_FRAME:AddMessage("The value of index "..k.." is "..v); | |||
end; | |||
Output: | |||
The value of index 1 is a | |||
The value of index 2 is b | |||
The value of index 3 is c | |||
The value of index 4 is d | |||
