In the editor when a string contains a variable set the text color of the varible to the one defined for variables.
Ex.
print "The color is $color.\n";
$color would be the color of variables, the rest of the string would be the color for strings.
This is similiar to the behavior in vim.
Thanks.
Diff:
Rather unlikely, as it requires a new parser for strings. Closing as duplicate of https://sourceforge.net/p/e-p-i-c/feature-requests/141/
