Hello

I have such a problem.

My mud outputs me a string, beginning with the "tab character", and continuing with consequent characters "Str" (and further nonspecial characters): so this mud's output string is like:

" Str..."

I enabled "con {convert meta} {on}". It shows me that string as

"\C-iStr..."

(where "\C-i", as I guess, is "tab character").

I need to write substitute triggering this string (which replaces it to something new). Please help me how to write substitute that will trigger that string (by now, no luck... )

Looks like you're running an old tt++ version.

In the current version it should show \t for tabs, and you can use \t in your subs and actions to trigger tabs.

Then, in new version, I do this like following?:

#sub {^\tStr...} {newtext}

?

--------------------------------------

One new question.

What is the correct format for checking by regexp if the string is empty.

Please, give an example.

[Scandum]

Yes.

To check for an emptry string use something like #gag {^$}
