string containing * (asterisk)

[NewzNZ]

Hi there

Am trying to detect strings with * (asterisks) in them to do (something)...

Have tied:

Code: Select all

if {[string match "{*\*}*" $tt]}
and
if {[string match "*\**" $tt]}

...but no luck. Any help would be appreciated!
Cheers

Code: Select all

% set text "* bla bla * bla"
* foo
% string first * $text
0
% set text "bla bla * bla"
bla bla * bla
% string first * $text
8

as you can see it returns the position of first match.

Playing in partyline, I first did:

Code: Select all

.set testtext "bla bla * bla"

Next:

Code: Select all

<myhandle> .tcl string match {*\**} $testtext
<botnick> Tcl: 1

Compared to yours, all I did was move the last asterisk to be inside the curly braces.

For the heck of it, I then played with it some more:

Code: Select all

<myhandle> .tcl string match {*\* *} $testtext
<botnick> Tcl: 1
<myhandle> .tcl string match {* \* *} $testtext
<botnick> Tcl: 1
<myhandle> .tcl string match {* \*  *} $testtext
<botnick> Tcl: 0
<myhandle> .tcl string match {* \* *} $testtext
<botnick> Tcl: 1

I hope this helps.
