Yacc
Yacc (Yet Another Compiler Compiler) is a parser generator tool used in compiler construction and language processing. It takes a formal grammar specification as input and generates source code (typically in C) for a parser that can analyze and process input based on that grammar. It is commonly used to build compilers, interpreters, and other language processing tools.
Developers should learn Yacc when working on projects that involve parsing structured text, such as creating domain-specific languages, implementing compilers, or building interpreters for programming languages. It is particularly useful in academic and legacy systems where C-based parsing is required, as it automates the generation of efficient parsers from grammar rules, reducing manual coding effort and minimizing errors.
