|
|
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."
