Summary: A fast lexical analyzer generator
Description:
flex is a tool for generating scanners: programs which recognized
lexical patterns in text. flex reads the given input files for a
description of a scanner to generate. The description is in the form
of pairs of regular expressions and C code, called rules. flex
generates as output a C source file, lex.yy.c, which defines a routine
yylex(). This file is compiled and linked with the -lfl library
to produce an executable. When the executable is run, it analyzes
its input for occurrences of the regular expressions.
Whenever it finds one, it executes the corresponding C code.
The behaviour of Flex has undergone a major change since version
2.5.4a. Flex scanners are now reentrant, you may have multiple
scanners in the same program with differing sets of defaults, and
they play nicer with modern C and C++ compilers. The Flip side is
that Flex no longer conforms to the POSIX lex behaviour, and the
scanners require conforming implementations when flex is used in ANSI
C mode. The package flex-old provides the older behaviour.
