@webassemblyjs/helper-code-frame

What is @webassemblyjs/helper-code-frame?

The @webassemblyjs/helper-code-frame npm package is designed to help generate code frames in WebAssembly files. This is particularly useful for debugging and error reporting, where you need to highlight specific parts of the code to the user.

What are @webassemblyjs/helper-code-frame's main functionalities?

Generate code frames

This feature allows developers to generate a code frame from a WebAssembly source code. It highlights a specific part of the code based on the provided location, which is useful for pinpointing errors or important sections in the code.

const { codeFrameFromSource } = require('@webassemblyjs/helper-code-frame');
const wasmSource = '...';
const location = { start: { line: 1, column: 5 }, end: { line: 1, column: 10 } };
const frame = codeFrameFromSource(wasmSource, location);
console.log(frame);

Other packages similar to @webassemblyjs/helper-code-frame

babel-code-frame

Similar to @webassemblyjs/helper-code-frame, babel-code-frame provides functionality to generate code frames for JavaScript files. It is used extensively in the Babel compiler to help developers understand where errors occur in their JavaScript code. While @webassemblyjs/helper-code-frame focuses on WebAssembly, babel-code-frame is specific to JavaScript.

highlight.js

While not exclusively for code frames, highlight.js is a syntax highlighter that can be used to visually distinguish code blocks, similar to how code frames highlight specific parts of code. It supports multiple languages, including JavaScript, but does not have built-in support for WebAssembly like @webassemblyjs/helper-code-frame.
