COMPILER DESIGN

Detailed explanation-1: -Parser Generators They take in a grammar as input and produce Java code to parse input.

Detailed explanation-2: -Parsing, syntax analysis, or syntactic analysis is the process of analyzing a string of symbols, either in natural language, computer languages or data structures, conforming to the rules of a formal grammar. The term parsing comes from Latin pars (orationis), meaning part (of speech).

Detailed explanation-3: -In computing, parsers create logical diagrams called trees. The purpose is to help the compiler understand the context of each token and its relationship to the underlying structure of the source code. Parsers are widely used in the following technologies: Java and other programming languages.

Detailed explanation-4: -Write many functions and keep them small. In every function, do one thing and do it well. Do not try to use regexps for parsing. They don’t work. Don’t attempt to guess. When unsure how to parse something, throw an error and make sure the message contains the error location (line/column).
