AriaLinter goal is twofold:
- provide a simple accessibility linter for HTML documents
- provide a Grunt task based on the linter in order to integrate accesibility best practices right into the developer workflow
The demo is currently deployed in http://arialinter.aws.af.cm/.
This plugin requires Grunt ~0.4.0
If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
$ npm install grunt-arialinter --save-dev
Once the plugin has been installed, it can be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-arialinter');
Afterwards, files, markup, and url's can be linted:
grunt.initConfig({
arialinter: {
files: [
'https://www.google.com/',
'./templates/*.html',
'<!doctype html><html lang="en"><head><title>titulo test</title></head><body style="background-color: white;"> <h1 style="color: black;">hola</h1><img src="asdf.jpg" alt="woop" /> <div class="entry"> <p>{{title}}</p> <h2>By {{author.name}}</h2> <div class="body">{{body}}</div></div> </body> </html>'
],
options: {
templates: true,
levels: 'A'
}
}
});
grunt.registerTask('default', ['arialinter']);
Options:
- templates: if templates is true then a subset of the rules will be run. This subset comprises those rules that can be checked against a static HTML template. Rules that require checking the correct event-handlers or any other dynamic condition wont be run. By contrast, if templates is false then all rules will be run
- levels: indicates which rules will be run according to the level they belong to. If you dont specify any level, it'' run for all the levels.
You can also use it with nodejs like a regular library
Install the package from npm
$ npm install arialinter --save-dev
Then, using arialinter, is as easy as:
var AriaLinter = require('arialinter');
var linter = new AriaLinter();
linter.initialize(fileOrUrl, function() {
if (linter.evaluate()){
console.log('success');
} else {
console.log('failed');
}
});
You can also pass an options argument to the evaluate() method:
var AriaLinter = require('arialinter');
var linter = new AriaLinter();
linter.initialize(fileOrUrl, function() {
if (linter.evaluate({level: 'A', template: true})){
console.log('success');
} else {
console.log('failed');
}
});
To run arialinter from the command line:
$ npm install -g arialinter
Display all the rules
$ arialinter --rules
Execute the linter just for templates
$ arialinter --templates test/testFiles/template.html
Execute the linter using all the rules of the level A
$ arialinter --level A test/testFiles/index.html
Execute the linter using all the rules of the level A and the rules that just apply for templates
$ arialinter --level A --templates test/testFiles/index.html
