regexp -all bad switch? why?

Hi,

I have some tcl problem.
The shell server I use has the following tcl versions

[15:48] TCL Version: 8.2
[15:48] TCL Patchlevel: 8.2.3

I am using a script which utilizes regular expressions.
Using 'regexp -all'.

When I execute the script it says -all is a bad switch.
And use others such as -nocase, -indices and bla bla.

What can be the problem? The tcl version? It doesn't
support regexp -all.

When I simply use regexp without any switches it works
fine or with all other switches except -all. Even regular
substitions, regsub -all works fine... but why not regexp -all?

Does anyone know the answer, maybe?

As the manual page for Tcl 8.2 indicates, it doesn't have a -all trigger (In Tcl 8.2, that is. Tcl 8.3 and up have it.).

Thanks... for letting me know.
I'll insist my admin to upgrade to the newer versions
as the regexp -all is quite a usefull and common command
and I need to use it in quite alot of my tcls

you can always use string map ...

string map?

or did you mean

string match?

I am aware with what string match does (similar to regexp -all)
but have no idea of string map.

i ment string map, you use it like this:

Code: Select all

set str [string map {"b" "B"} "abcd"]

and it'll replace the 'b' with a 'B'

thats doing the same as:

Code: Select all

regsub -all "b" "abcd" "B" str

Oic... thanks again... I will look that up in the
manual as well.. good command to use to
so I can change regsub to string map.

regsub is slow and string manipulation
commands are fast as we know.

Didn't he wanted the regexp not regsub?
