# The devel/flex port

## flex-2.5.35 – fast lexical analyzer generator

## Description

    Flex is a tool for generating scanners. A scanner, sometimes called a
    tokenizer, is a program which recognizes lexical patterns in text. The
    flex program reads user-specified input files, or its standard input
    if no file names are given, 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 a C source file named, "lex.yy.c",
    which defines the function yylex(). The file "lex.yy.c" can be compiled
    and linked to produce an executable. When the executable is run, it
    analyzes its input for occurrences of text matching the regular
    expressions for each rule. Whenever it finds a match, it executes the
    corresponding C code.
