LEX file extension - Lex or Flex file
What is lex file? How to open lex files?
File type specification:
The LEX file extension is associated with the Lex and Flex.
In computer science, lex is a program that generates lexical analyzers ("scanners" or "lexers"). Lex is commonly used with the yacc parser generator. Lex, originally written by Eric Schmidt and Mike Lesk, is the standard lexical analyzer generator on many Unix systems, and a tool exhibiting its behavior is specified as part of the POSIX standard.
Lex reads an input stream specifying the lexical analyzer and outputs source code implementing the lexer in the C programming language.
Though traditionally proprietary software, versions of Lex based on the original AT&T code are available as open source, as part of systems such as OpenSolaris and Plan 9 from Bell Labs. Another popular open source version of Lex is Flex, the "fast lexical analyzer".
