 Posted: Sun Mar 03, 2019 8:34 pm Post subject: string containing * (asterisk) |
 |
|
Hi there
Am trying to detect strings with * (asterisks) in them to do (something)...
Have tied:
| Code: |
if {[string match "{*\*}*" $tt]}
and
if {[string match "*\**" $tt]}
|
...but no luck. Any help would be appreciated!
Cheers |

| Code: |
% 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: |
.set testtext "bla bla * bla"
|
Next:
| Code: |
<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: |
<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.
