Zugg Software :: View topic - Differences between calling an alias and triggering a command trigger

Posted: Tue Jan 06, 2009 6:18 pm

I need a little refresher on how aliases and command triggers can be called from within an alias.

If I'm in an alias and I want to call an alias and the name of the alias is inside a variable, I think I can do the following to call the alias:

#var function_name function1
@function_name

However, if instead of having an alias named function1 I have a 'command' type trigger with "^function1" as the trigger text, the trigger doesn't fire.

Is there any way for text output from an executing alias to trigger a 'command' trigger?

You forget about "Start line with command" requirement in CMUD. Your @function_name alone should not work.
Write it as #EXEC @function_name - it will call an alias with name of "function1" or trigger Command Input trigger with "^function1" pattern - it depends on what setting you have.

What settings does it depend upon for triggering the command input trigger?

I meant that if you have the function1 alias, then "#EXEC @function_name" will call it; if you have Command Input trigger with input pattern "^function1", then "#EXEC @function_name" will cause it to fire. Just use "#EXEC @function_name" in any case. Sorry if I hadn't write my previous post clear.

If all you're trying to do is get a trigger to fire, though, you might find it easier to move the code from the trigger into something else (alias, function, event) to save having to go through the trigger engine. Calling the script directly will always be faster than running a regex.

I'd love to change it, but I thought this was the best way to accomplish it. What I'm doing is using the command input trigger to match when any of the directions are used, ie "n|ne|e|se|s|sw|w|nw|in|out" and if they are then I set some variables so I know in my own code that I'm moving. Since I want the same thing to run when any of those 10 things are input, I used a command input trigger "^\s*(n|ne|e|se|s|sw|w|nw|in|out)" and then I only have to write the code once. If I switched this to aliases then I'd have to create 10 aliases.

Is there a better way to accomplish this?

Maybe try #send instead of #exec?

I'll investigate further to see if I can figure out the discrepancy.

It should and does fire the command input trigger (in a mocked up example), but somehow in my event it is not. It may be a bug in Cmud or something really strange I have going on, but it isn't firing in mine like it should. I've tried debugging this, but I ran into a whole other set of bugs so it may be a while until I can properly untwist this one.

From what you've described in the other postings, your package(s) have gotten really mucked up. Once that happens, almost anything could happen. You might have to copy your code into new packages.

That's a really complex way to match cardinal directions. Very Happy

Is the '?>' equivalent to the '?:'?
