35b9e423 | 75 | "Flex is a tool for generating scanners. A scanner, sometimes |
e2b2c466 | 76 | called a tokenizer, is a program which recognizes lexical patterns in |
35b9e423 | 77 | text. The flex program reads user-specified input files, or its standard |
e2b2c466 | 78 | input if no file names are given, for a description of a scanner to |
35b9e423 EB |
79 | generate. The description is in the form of pairs of regular expressions |
80 | and C code, called rules. Flex generates a C source file named, | |
81 | \"lex.yy.c\", which defines the function yylex(). The file \"lex.yy.c\" | |
82 | can be compiled and linked to produce an executable. When the executable | |
e2b2c466 | 83 | is run, it analyzes its input for occurrences of text matching the |
35b9e423 | 84 | regular expressions for each rule. Whenever it finds a match, it |
e2b2c466 | 85 | executes the corresponding C code.") |
