Script bracelevel.tcl: Purpose: to output to the screen a tcl script with indicators of the nesting level of the code.
# prefix the current brace level on each line -jcw
# I guess the reason for this script is to help in finding missing braces AK.
proc bracelevel {str} {
set lev 0
set out ""
foreach l [split $str \n] {
append out $lev \t
foreach c [split $l ""] {
append out $c
switch -- $c \{ { incr lev } \} { incr lev -1 }
}
append out \n
}
return $out
}
puts [bracelevel [read stdin]]Output of running bracelevel.tcl with itself as input:
