asm.js-lint

0.1.3 verified Fri May 01 auth: no javascript deprecated

asm.js-lint is a linting plugin for CodeMirror that validates asm.js code. Version 0.1.3, released around 2013, is the latest stable release. The package is minimal and designed to be used alongside CodeMirror's existing lint addon. It provides a helper script for validation and requires browserification for development. This plugin is rarely updated and has limited adoption, serving as a niche tool for asm.js development within CodeMirror.

Common errors

error Cannot find module 'asm.js' ↓

cause Development build requires asm.js to be installed globally or locally.

fix

Run 'npm install asm.js' before browserifying.

error Uncaught TypeError: Cannot read property 'asm' of undefined ↓

cause CodeMirror's lint addon has not been loaded before asm-lint.js.

fix

Ensure the script tag for 'addon/lint/lint.js' is included before asm-lint.js.

error asm-lint.js requires a CodeMirror instance ↓

cause asm-lint.js expects CodeMirror to be globally available.

fix

Load CodeMirror as a script tag before asm-lint.js.

Warnings

deprecated Project is no longer maintained. Use it at your own risk. ↓

fix Consider using a modern linting tool for JavaScript asm.js modules.

gotcha The package does not list CodeMirror as a peer dependency, leading to potential version mismatches. ↓

fix Ensure you manually install a compatible version of CodeMirror.

gotcha The library requires browserify for development builds, which may not be obvious. ↓

fix Run 'browserify src/asm-lint-helper.js -o dist/asm-lint-helper.compiled.js' after installing asm.js.

gotcha The plugin only works in browser environments; Node.js usage is unsupported. ↓

fix Use only in browser-based CodeMirror instances.

Install

npm install asm.js-lint

yarn add asm.js-lint

pnpm add asm.js-lint

Imports

asm-lint

wrong

Using npm package without proper script loading

correct

Include script tag: <script src="<path-to>/asm.js-lint/lib/asm-lint.js"></script>

This library is not a standard npm module; it must be loaded as a script in the browser.

asm-lint-helper

wrong

Requiring via Node.js require()

correct

Include script tag: <script src="<path-to>/asm.js-lint/dist/asm-lint-helper.compiled.js"></script>

The helper is a browserified script; it cannot be used in Node.js.

CodeMirror.asmLint

wrong

Using 'asm' as a mode without enabling lint

correct

Use the 'asm' lint option: CodeMirror.fromTextArea(element, { mode: 'asm', lint: true })

The plugin registers itself as a lint source for the 'asm' mode in CodeMirror.

Quickstart

Shows how to set up asm.js linting in CodeMirror with script tags and configuration.

// Ensure you have CodeMirror and its lint addon included.
// Then add script tags:
// <script src="path/to/codemirror.js"></script>
// <script src="path/to/addon/lint/lint.js"></script>
// <script src="path/to/asm.js-lint/lib/asm-lint.js"></script>
// <script src="path/to/asm.js-lint/dist/asm-lint-helper.compiled.js"></script>
//
// Initialize CodeMirror with asm linting:
var editor = CodeMirror.fromTextArea(document.getElementById('code'), {
  mode: 'asm',
  lint: true
});
