Branch: pkgsrc-2022Q4, Version: 2.6.4, Package name: flex-2.6.4, Maintainer: pkgsrc-users

flex is a tool for generating scanners: programs which recognized
lexical patterns in text. flex reads the given 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 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.
