 Posted: Tue Aug 05, 2008 12:22 pm Post subject: replace every "*" in string |
 |
|
Hi,
I'm keeping the channels banlist in a text file but got a problem removing the entries from that file as I can't figure out how to escape the asterisks.
sed expects every "*" and "!" to be escaped like "\*" and "\!"
What's the easiest way to replace _every_ "*" with "\*" in a given string? (Replacing just one isn't a problem, but for 5 my code had around 50 lines and is fugly) |

Regsub with a regular expression:
| Code: | | set maskedString [regsub -all -- {\*|!} $oldString {\\\0}] |

doesn't work 
Tcl error [delban]: wrong # args: should be "regsub ?switches? exp string subSpec varName"
Entered the command exactly like you said, only changed the variable names: | Code: | | set maskedString [regsub -all -- {\*|!} $mask {\\\0}] |
also tried with just "{\*}" as expression but that failed as well. |

That's odd... which version of tcl are you using?
Most versions of tcl have the varName argument optional. Nevertheless, try using something like this instead then:
| Code: | | regsub -all -- {\*|!} $mask {\\\0} maskedString |
