How to scan the command line for an item link with spaces

Hello there.

I am nearly finished with my addon "restack" but now I have a little problem with scanning the command line.

I use a function GetCmd() from somewhere, but that one splits arguments when there is a space in the line.

So when I get a line with a link in it that has space, it breaks.

What I want to have is a function that does the following:

cmdline = "a test" -> returns "a","test"

cmdline = "4231:0:0...[name with spaces] 3" -> returns "4231:0:0...[name with spaces]","3"

I know there must be a very easy regex for this, if I only would be better in this. :-)

Pls help.

why cant you have each word(characters seperated by space) returned seperatly?

what are you trying to do

I guess you could do

local thiscommandarray =GetCommand()
for key, value in thiscommandarray do
if(not thiscommandstring)and (value) then thiscommandstring = value end
elseif(thiscommandstring) and (value) then thiscommandstring = thiscommandstring.." "..value end

that should do what you want...dunno if its the best way though

see which pattern match comes first.
function parseCommand( cmdLine )
local a={}
local linkPat = "|?|H.-|h.-|h";
local wordPat = "%S+";

while ( ""~=gsub(cmdLine, "%s", "") ) do
	local word, link, pattern;
	word = strfind( cmdLine, wordPat);
	link = strfind( cmdLine, linkPat);
	pattern = word and link;
	if ( word and not link or pattern and word < link ) then
		pattern = wordPat;
		pattern = linkPat;
	cmdLine = gsub( cmdLine, pattern, function(i)
		table.insert(a, i);
	end, 1 )
return a;
