unmatched open quote in list

I get this error "unmatched open quote in list"
I guess it's because I need to escape something in my string... so I was wondering if there was a way to escape a string and unescape it... some functions?

This is not due to a character being un-escaped

It is likely to have allready been excaped, yet due to bad handling of strings (using list commands), it is processed wrong.

If you post the script, we can pinpoint the problem.

I think I fixed the problem with

Code: Select all

regsub -all "\\\\" $text "" text

It works now anyway, are there any tcl functions used for escaping, and unescaping? besides subst? because subst only escapes?

Your regsub is a temporary solution. It could break again when you modify the script. PPslim was right in saying that it is due to bad handling of the string.

You are probably saying [lindex $text 1] or something. To correct this code, use [split] on $text, not regsub.

Nice, thanks... so list functions suck?

how do I make split work like lindex?

No list functions don't suck. But they are not designed to operate on strings. A word in a string does not equal an element in a list.

Split takes a string and turns it into a list, based on spaces. So after split, each word is an element in a list.

So to use lindex and split together, simply say:

lindex [split $text] 1

Thank you, I'll try that...

Code: Select all

set text [string trimleft $text "$trigger "]

This code seems to make trubble...

If $text is "$trigger ic is fun"
Then it not only strips down the "$trigger " but also the i in "ic"

Is this the same problem?

Hehe no that's a misunderstanding of what the trim command does. You give it a list of characters and it trims them. You're giving it a whole word, but it only sees individual letters. So if there's an i in your trigger, it trims all i's, etc.

You're probably better off using regsub.

oh... hehehe, I see... learning a lot here

I was using regsub before, but that replaces all occurences of the pattern, I only want to kill the first word in a string...

It only replaces all matches if you use the -all flag.

regsub {^[^\w]*[\w]+[^\w]*} $text "" text

That replaces the first word and any space around it.
