This article introduces the fundamentals of compiler front‑end development, covering lexical analysis with finite automata, syntax analysis using context‑free grammars and parsing strategies, and semantic analysis concepts, while providing practical Antlr examples for Java code tokenization, parsing, and semantic checks.
This article walks through the design and implementation of a lightweight JSON parser in Java, covering the underlying lexical and syntax analysis, token definitions, core parsing algorithms, testing strategies, and a brief demonstration of JSON beautification, providing developers with a clear understanding of JSON processing fundamentals.
This article explains ECMAScript's cover grammars and finite lookahead mechanisms for resolving ambiguous syntax, focusing on arrow function parameter lists versus parenthesized expressions.
This tutorial explains how to implement a simple LL(1) parser in Go for SQL queries, covering lexical analysis, syntax analysis, finite‑state‑machine strategy, and testing, providing complete code snippets and practical guidance for developers interested in parser construction.
