Dinghy: Versatile AST Generator for Shell Scripts and Dockerfiles

Dinghy is a robust library designed to generate Abstract Syntax Trees (ASTs) for both shell scripts and Dockerfiles. It offers developers a solution for parsing and analyzing these files, facilitating advanced automation and analysis tasks.

For detailed documentation, please visit https://durieux.me/Dinghy/.

Features

• AST Generation: Effortlessly generate ASTs for shell scripts and Dockerfiles.
• Parsing: Accurately parse complex Dockerfiles, capturing their structure and directives.
• Traversal: Traverse the AST to perform various analysis tasks such as linting or modification.
• Querying: Extract specific information about commands, arguments, and more with ease.
• Modular Design: Built with modularity in mind, enabling easy extension and customization.
• TypeScript Support: Fully compatible with TypeScript for type-safe development.

Installation

npm install @tdurieux/dinghy

Usage

import dinghy from "@tdurieux/dinghy";

// Parse Dockerfile
const dockerAST = dinghy.parseDocker(/* file path or file content */);
dockerAST.traverse((node) => {
  if (node instanceof dinghy.AbstractValueNode) {
    console.log(node.value);
  }
});

// Parse Shell Script
const shellAST = dinghy.parseShell(/* file path or file content */);
shellAST.traverse((node) => {
  if (node instanceof dinghy.AbstractValueNode) {
    console.log(node.value);
  }
});
Copy

Additional examples are available in the library's test suite.
