That regular expression only matches (non-augmented) top-level
variable assignment statements. It's also a legible regular expression
- silly to say the least!
This regex should be better:
"^ *\\([a-zA-Z0-9_]+\\)
*\\(?:+\\|*\\|/\\|//\\|%\\|**\\|>>\\|<<\\|&\\|\\^\\||\\)?="
I haven't tried this rx regex, but maybe something along the lines of...
(rx bol (0+ space) (group (1+ (any alnum ?_))) (0+ space)
(any "=" "+=" "-=" "*=" "/=" "//=" "%=" "**=" ">>=" "<<=" "&=" "^=" "|=")
