That is the root of the issue.  You shouldn't be parsing source code
with ad-hoc tools.  You need to use a real compiler.  Just because it
happened to work with, say C, does not mean that you got it right.  I
doubt that a program that you described was correctly handling, say,
line continuations in comments.

The bottom line is, you need to use a real compiler frontend to parse
source code.
