including a "[" in a regexp

[bradfisher133]

Hello All,

I want to search a string containing brackets or braces.
How do I escape brackets or braces in a regexp command?
For example, consider the following illegal regexp command:

set i 5
regexp "path($i)" "path(5)"

I want the braces to be viewed as a character, not a grouping device.

thanks

Not sure what you are doing with that regexp call but usually when i want tcl to ignore grouping devices i put a \ just before any characters that I want ignored. For instance

>set i 5
>puts $i
5
>puts \$i
$i

and it works for () {} [] just make sure you get the opening and closing braces/paren/brackets
