If I change from:
   
        <trigger
        enabled="y"
        match="^{chan ch=(?<channel>\w+)}(?<msg>.*)"
        regexp="y"
        script="chats"
        omit_from_output="y"
        sequence="100"
        ></trigger>

to 

    <trigger
    enabled="y"
    multi_line="y"
    lines_to_match="2"
    match="^{chan ch=(?<channel>\w+)}(?<msg>.*)$\n$"
    regexp="y"
    script="chats"
    omit_from_output="y"
    sequence="100"
    ></trigger>

It seems to work (calls the chats function), but no longer omits from output. Am I doing it wrong?

Multi-line triggers can't omit from output.

The way they are implemented, it gathers output lines (the last 200) into a deque, and then for multi-line triggers concatenates the required number into a string, then submits that string to the regexp handler.

This method ensures that any intervening note lines, or player input, are not counted as part of the multi-line sequence.

However since the multi-line triggers are not as immediate as single-line triggers (ie. they didn't *just* arrive) then omitting from output, and other things like colouring output, are disabled for them.

The only way you can omit a sequence of lines (eg. an inventory) is to detect the start of it, omit that, detect the middles lines, one by one, and then detect the end of it.

See:

Scroll down to "Limitations on multi-line triggers".
