Traverses the AST to perform static analysis, semantic checks, and error detection.

Package Exports

  • @je-es/ast-analyzer
  • @je-es/ast-analyzer/dist/ast-analyzer.js
  • @je-es/ast-analyzer/dist/ast-analyzer.mjs

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@je-es/ast-analyzer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme


ast-analyzer

A static analysis tool that traverses the AST
to perform semantic checks, validation, scope resolution, and error detection.

  • Install

    npm install @je-es/ast-analyzer
    import { Analyzer } from "@je-es/ast-analyzer";

  • Usage

    // suppose we want to analyze the represented AST for this statement:
pub let mut x: i32 = 42
    // [1] Create syntax
const syntax = Syntax.create({ // :: using @je-es/syntax(parser/lexer)
        name     : 'Kemet',
        version  : '0.0.1',
        lexer    : lexerRules,
        parser   : parserRules,
        settings : parserSettings
    } as syntax.SyntaxConfig
);

// [2] Parsing the input
const parser_result = syntax.parse('pub let mut x: i32 = 42');

// [3] Create module using the parser result
const main_module   = AST.Module.create( // :: using @je-es/ast
    // Name
    'main',

    // Statements
    parser_result.ast.length > 0
        // in my case, first item refers to an array of stmts.
        ? parser_result.ast[0].getCustomData()! as AST.StmtNode[]
        // otherwise, empty module.
        : [],

    // Metadata
    { path: './src/main.k' }
);

// [4] Create program with the created module
const program = AST.Program.create([main_module], { entryModule: 'main', path: './' });

// [5] Create analyzer for the created program
const analyzer = Analyzer.create({ debug: 'off' });
const analyzer_result = analyzer.analyze(program);
