Add a multiline trigger with addtriggerex alias?

I'd like to make triggers that match on room descriptions and output my own notes, I know it's possible with world.DoCommand "MakeMultiLineTrigger"

However I plan on doing quite a few of these triggers so I was hoping to move the trigger creation to the command line for speed and less futzing around through the full list of triggers.

I thought one way I could set it up would be similar to an addtriggerex alias but it would also have to parse the clipboard text into a multiline trigger the same way world.DoCommand "MakeMultiLineTrigger" does to the input box... I'd be grateful for any insight.


<aliases>
  <alias
   match="room * "
   enabled="y"
   group=""
   send_to="12"
   sequence="100"
  >
  <send>
AddTriggerEx ("", GetClipboard(), "%1", trigger_flag.Enabled, custom_colour.NoChange, 0, "", "", 0, 0)

</send>
  </alias>
</aliases>

You might find it easier to use addxml (see http://www.gammon.com.au/forum/?id=7123).

However your core problem, if I understand the question correctly, would be to take a multi-line room description, and turn it into a regular expression.

This would basically involve these things:

Converting things (like *, + and brackets) into an escaped form, so that they don't get misinterpreted. A simple string.gsub should do it, with a list of characters you need to escape, and put a backslash in front of them. I think basically any character except A-Z, 0-9 could use such a conversion (excepting newlines). So something like this might do it:
```
s = string.gsub (s, "[^%d%a%c]", "\\%1")
```
Converting newlines to \n in the string
Put \A (start of subject) at the front, and \z (end of subject) at the end.
Count the newlines, and make that, plus one, be the number of lines to check in the multi-line trigger.

Bah, I haven't found success yet but thanks for pointing me in the right direction.
