#131 Error when running on Postgres lex file

[txntxn]

Great project!

Let's say you run JFlex on the postgres lex file:

https://github.com/postgres/postgres/blob/master/src/backend/parser/scan.l

You get the following error:

Reading "/Users/txn/utils/i386-apple-darwin13.1.0/src/postgresql-9.3.5/src/backend/parser/scan.l"

Error in file "/Users/txn/utils/i386-apple-darwin13.1.0/src/postgresql-9.3.5/src/backend/parser/scan.l" (line 388):
Unexpected character

{whitespace} {
^
1 error, 0 warnings.

The lex file you pointed to is for lex/flex, not JFlex.

See this section of the JFlex manual for information on porting lex/flex specifications to JFlex: http://jflex.de/manual.html#SECTION00092000000000000000
