strings

[Snapple]

hmm
is there a command to do like in mirc if (%var isin %var2)....
I mean, for example %var will be #Help
and %var2 will be #OperHelp #Help #Mirc
then it will return true
anyone know?

Consult the string manual page.

Command: string match

Purpose: Test whether a given string matches a specified glob-style pattern.

Command Syntax: string match -nocase pattern string

Return Value: 1 if string matches pattern; 0 if not


The string match subcommand tests to see whether a
given string matches a specified glob-style pattern.
If you specify the -nocase option, the match is evaluated without regard to case.

If you don't use this option, you may end up with a different result than you intended.
For example, the character "_" lies between the upper-case and
lower-case ASCII letters in the Unicode collating sequence.

So if your pattern is [A-z], the underscore character will match the pattern.
If you intend to match only an alphabetic character,
you should specify -nocase and a pattern of [a-z].

Here's an example:

Code: Select all

set input "Help" 
set c_list "OperHelp Help Mirc"

  if {[string match -nocase "$input" "$c_list"]} {

Would return true

I already used string last... which working just fine, thanks.
hmm
I have another question, how can I remove from a string a part of it?

[Dedan]

this might work:

Code: Select all

set input "Help" 
set c_list "OperHelp Help Mirc"

proc update:list {} {
  global input c_list
  if {[string match -nocase "$input" "$c_list"]} {
    set position [lsearch -exact $c_list $input]
    set c_list [lreplace $c_list $position $position]
  }
}

give it a try

First get it's position in the list with lsearch then remove it with lreplace.

this might work:

Code: Select all

set input "Help" 
set c_list "OperHelp Help Mirc"

proc update:list {} {
  global input c_list
  if {[string match -nocase "$input" "$c_list"]} {
    set position [lsearch -exact $c_list $input]
    set c_list [lreplace $c_list $position $position]
  }
}

give it a try

Since we are talking about strings this is NOT the way to go..
As mentioned numerous times on the forum, you can NOT treat strings as lists and visa versa without first doing conversions.

If there is particular text you are trying to remove from a string, might I suggest either using regsub or string map.

Thanks strikelight.

Would you care to expand on the subject?

Sounds like a good candidate for the FAQ section.

Nothing I could say that hasn't already been said here in the forum,
and also @ http://www.peterre.com/characters.html

Also, do consult the regsub manual.
