String map works with literals but not with variables
0
This is the script that I'm running
set input_file [ open $ORIGINAL_TESTS_FILE r ];
set output_file [ open $TESTS_FILE w ];
set CLASS_NAME "RandTest";
set NEW_CLASS_NAME "JuanDeLosPalotes";
while { [gets $input_file line] >= 0 } {
#echo $line
# Replacing string
set line [ string map { "RandTest" "JuanDeLosPalotes" } $line ];
#echo $line
puts $output_file $line
}
close $input_file
close $output_file
This reads a text file and replaces RandTest with JuanDeLosPalotes whereever it finds it.
However, if I replace this line
set line [ string map { "RandTest" "JuanDeLosPalotes" } $line ];
With this line
set line [ string map { $CLASS_NAME $NEW_CLASS_NAME } $line ];
It does not work (line remains unaltered).
What am I doing wrong?

Fixed it!!!
Curly braces prevent substitution. So I needed to use quotes.
set line [ string map "$CLASS_NAME $NEW_CLASS_NAME" $line ];
I case anyone needs it.
