Why is it so difficult to compare/catch [ and ] in tcl ... h

if {[string match *\[*\]* $var]} {
return 1
} else {
return 0
}

the characters [ and ] parsed by the string command as metacharacters, thus the double escapeage

if {([string match "]" "$var"]) || ([string match "[" "$var"])} {return 1} {return 0}

in short, enclose the brackets in quotes in your string match and that should identify it as a string and not a tcl bracket.

anyone know how to "catch" character [ and ] ?

I want to make a function "if there is [ and ] return 1"

tclsh
% set a x
x
% set b x
x
% string match $a $b
1
% set a "*[*]*"
*[*]*
% set b "[]"
[]
% string match $a $b
0
% set b "["
[
% string match $a $b
0
%
