Validator

The validator is a reference static analysis tool and language specification checker designed to verify that JavaScript source code strictly adheres to the defined grammar, type rules, and structural requirements of the asm.js subset standard. By inspecting source files without execution, it acts as a syntax linter that catches structural errors, malformed syntax, and standard violations early.

The tool parses source code into hierarchical token structures to analyze grammatical correctness and language feature usage. It measures code against formal grammar definitions and matches programmatic rules against syntax nodes to enforce strict language subset constraints, utilizing recursive tree traversal to check isolated language requirements efficiently.

Features

CLI Coding Standard Validators - Verifies JavaScript source files against structural rules and language standards to ensure strict subset compliance.
Asm.js Validators - Acts as a reference tool checking JavaScript source code specifically against asm.js language specification rules.
JavaScript Linters - Verifies the correctness and structural conformance of JavaScript code written for subset standards.
Language Compatibility Checkers - Ensures source code strictly follows defined grammar and type rules to verify subset standard conformance.
Subset Validations - Verifies that target source files strictly adhere to defined subset specifications before compilation.
Language Specification Compliance - Measures source code against formal language specifications to guarantee strict adherence to standard subset constraints.
Abstract Syntax Tree Parsing - Parses source code into structured syntax tree representations to analyze grammatical correctness and language feature usage.
Structural Rule Enforcement - Enforces strict language subset constraints by inspecting code structure against programmatic rules without execution.
Static Code Analysis - Inspects source code without execution to catch structural errors, malformed syntax, and standard violations early.
Tree Traversal - Traverses syntax trees recursively using visitor pattern logic to check isolated language requirements efficiently.

JSHint is a JavaScript static analysis tool and linter designed to detect errors and enforce coding standards. It functions as a syntax validator that scans source code to identify potential logic problems and programming mistakes before the code is executed. The tool provides a command line interface for analyzing files and directories. It supports the export of analysis results into standardized formats such as Checkstyle for integration with external build tools. Analysis is managed through a system of linting rule management and environment global configuration. This includes the ability

Esprima is a JavaScript parser that converts source code into a structured abstract syntax tree. It implements a specification-driven grammar to ensure compliance with ECMAScript standards, enabling the programmatic analysis and transformation of JavaScript programs. The project provides capabilities for lexical tokenization to break source code into individual symbols and static syntax validation to verify that scripts are well-formed without executing the code. Its functional surface covers JavaScript static analysis, lexical analysis, and the generation of abstract syntax trees.

Recast is a JavaScript AST parser and printer designed for automated code refactoring. It converts source code into abstract syntax trees that can be modified and then printed back into source code. The project focuses on formatting-preserving transformations, storing original whitespace and indentation metadata within syntax tree nodes to reconstruct code without losing its original layout. It also generates character-level source maps to maintain precise correspondences between original input and transformed output. The toolkit includes utilities for syntax tree manipulation using a visito

Unified is a syntax tree processing engine and content ecosystem designed to parse, transform, and serialize text content. It functions as a plugin-based content pipeline that converts raw text into structured abstract syntax trees using plain JavaScript objects for programmatic inspection and modification. The project distinguishes itself through a modular architecture that enables cross-ecosystem translation, allowing syntax trees to be converted between different specifications such as HTML and Markdown. It utilizes a system of immutable processor cloning and shared state containers, ensur
