LL file extension - Lex source code file
What is ll file? How to open ll files?
File type specification:
lex is a program that generates lexical analyzers. Lex is commonly used with the yacc parser generator. Lex 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 analyser 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 (fast lexical analyser).
