I'm new to (f)lex and I'd like to experiment writing a new language using a
syntax similar to Python (but with strong typing). However, I'm not know how
(or even whether) you can use flex for tokenising dedents.
E.g.
while true:
print
print
print "Done"
Should generate something like the following tokens:
WHILE
BOOL
":"
NEWLINE
INDENT
PRINT
NEWLINE
PRINT
NEWLINE
DEDENT
PRINT
STRING
NEWLINE
Any ideas?
Cheers,
Stuart
PS. Had a look in the through the Python distribution and could only find
the source for the grammar.
