Description-en: Flex-style scanner generator for C++
Flexc++ was designed after `flex'. Flexc++ offers as compared to flex's C++
option a cleaner class-design.
.
Flexc++ generates a scanner class that is ready for use, as well as a member
function producing the lexical scanner tokens (lex()). The class can easily
be provided with additional members without the need for polymorphic
functions. Consequently, classes generated by flexc++ have no virtual members
and actually have but one public member: lex(), replacing the old-style flex
and flex++ yylex() function.
.
Flexc++ offers many options, among which an option to define classes
generated by flexc++ in a separate namespace. This allows developers to
define additional symbols, even outside of the class generated by flexc++,
without encountering name-collision problems. With flexc++, artificial means
to prevent name-collisions, like the yy-conventions used by flex and flex++
are no longer required. Flexc++ generates C++ code. If C code is required,
flex should be used. Flexc++'s grammar requirements are highly compatible
with flex's requirements, so converting a flex grammar into a flexc++ grammar
should be fairly simple.
.
In addition to the flexc++ scanner generator itself and several skeleton
files, the package contains an extensive man-page, as well as a full manual
rewritten after the original flex manual, and several examples.
