|
The flex program generates scanners.
|
|
|
|
|
Scanners are programs which can recognize lexical patterns in text.
|
|
|
|
|
Flex takes pairs of regular expressions and C code as input and generates a C source file as output.
|
|
|
|
|
The output file is compiled and linked with a library to produce an executable.
|
|
|
|
|
The executable searches through its input for occurrences of the regular expressions.
|
|
|
|
|
When a match is found, it executes the corresponding C code.
|
|
|
|
|
Flex was designed to work with both Yacc and Bison, and is used by many programs as part of their build process.
|

|
|
You should install flex if you are going to use your system for application development.
