Extend String TLO to parse links

[dewey2461]

EQ now has active links in most of its text. It would be nice to have a way with in a macro to extract the link text.

String.LinkText[N] would return the TEXT portion of the Nth's link in the string.

For example a simple farming macro might detect when an item is left on corpse by advloot.

Event String:
-- You have decied to not loot 1 item(s): [Bloodstained Journal Vol.5]. The items(s) will be avialable to anyone after the corpse(s) unlock.--

The actual text for the link is hex 0x12, followed by 90 digits, followed by the text you can see and a matching 0x12.

To parse out the text of the link is painful because the link is coded with hidden character 0x12 that we have no way of passing in to the string Arg or Token methods.

The code to perform this function is fairly trivial but since it would need to be part of the string TLO it will take one of the Dev's to make it happen.

Tested it with the following macro snippet

Usage

Code: Select all

#event TEXT "You #*#"
#event TEXT "Your #*#"
#event TEXT "--You #*#"

Sub Event_TEXT(string line)
     /echo /mqlog LINE [${line}]
     /echo /mqlog LINK [${line.LinkText}]
/return

Went to Everfrost and cast some spells on mobs and got faction hits. Link some items etc.


Here is the TLO code

Code: Select all

	// Return the Text portion of the "Nth" link 
	// Item  Links : [0x12]0044BC000000000000000000000000000000000000000000000000000000000000000000000000000003B91A689Orbweaver Silk[0x12]
	// Spell Links : [0x12]63^6271^'Spirit of Vesagran[0x12]

	case LinkText:

		strcpy_s(DataTypeTemp, "");

		char *Src = (char *)VarPtr.Ptr;

		int N = GETNUMBER();
		if (N == 0) N = 1;
		int LinkLen = 92;										// This is the size of the link data. Change it for EMU's
		int i;

		while (Src && Src[0])
		{
			if (Src[0] == 0x12)
			{	
				Src++;											// Found the marker for the start of a link - skip first 0x12
				for (i = 1; i < LinkLen; i++)					// Loop to eat up to LinkLen characters
				{												
					if (Src[0] == '^' && Src[1] == 39)			// Check to see if we have a ending token  "^'"

						Src++;									// Eat one character and let next block eat 2nd

I don't remember where I have the list, but the first character after the first 0x12, tells you the type of link it is.

0 = Item Link
3 = Achievements Link

I'll try and find that list.

I may not need a complete list if they are get decoded the same way. It seems Item links are a fixed size while other 0x12 links all use a series of numbers with ^ to indicate breaks with a ^` at the end.

I did briefly toy with the idea of trying to make the TLO do something more interesting like return the raw data but ... too much work.
