SSLR in Action

If you want to start working with SSLR, you must be familiar with the following standard concepts : Lexical Analysis, Parsing Expression Grammar and AST(Abstract Syntax Tree). From there you can directly have a look to the source code of the JavaScript (lexer/parser, rules), Flex (lexer/parser, rules) or Python (lexer/parser, rules) plugins to see how those languages are analysed with help of SSLR.
