Overview
PHP parser for the output of reid/node-jslint, get lovely things such as:
- a list of errors
- error counts
- % of content scanned
- bunnies
If you're building a PHP-based application that programmatically interfaces with node-jslint, this is for you.
Usage
The "Hello World" example
Running JSLint from the command line through node-jslint can give you a nice collection of error information to process:
node jslint.js --json /home/jon/www/gears.simplytestable.com/src/SimplyTestable/WebClientBundle/Resources/public/js/app.js [ "/home/jon/www/gears.simplytestable.com/src/SimplyTestable/WebClientBundle/Resources/public/js/app.js", [ { "id":"(error)", "raw":"Missing 'use strict' statement.", "evidence":" var nextTaskIdCollection = [];", "line":6, "character":5, "a":"var", "reason":"Missing 'use strict' statement." }, { "id":"(error)", "raw":"Unexpected '{a}'.", "evidence":" ", "line":7, "character":1, "a":"(space)", "reason":"Unexpected '(space)'." },
Let's parse that in a unit test and see what we can get:
<?php $parser = new webignition\NodeJslintOutput\Parser(); $parser->parse($rawOutputString); $nodeJsLintOutput = $parser->getNodeJsLintOutput(); $this->assertNotNull($nodeJsLintOutput); $this->assertEquals(7, $nodeJsLintOutput->getEntryCount()); $this->assertEquals(4, $nodeJsLintOutput->getPercentScanned()); $outputEntries = $nodeJsLintOutput->getEntries(); foreach ($outputEntries as $outputEntry) { /* @var $outputEntry \webignition\NodeJslintOutput\Entry\Entry */ echo $outputEntry->getReason() . "\n"; echo $outputEntry->getEvidence() . "\n"; }
See? Useful. We can see how many entries are in the output, what the entries are and how much of the linted content was scanned.
Seeing Why JSLint Stopped Scanning
Sometimes JSLint encounters too many errors, sometimes it stops scanning if the code quality is just not up to scratch.
It's nice to see why scanning stopped.
<?php $parser = new webignition\NodeJslintOutput\Parser(); $parser->parse($rawOutputString); $nodeJsLintOutput = $parser->getNodeJsLintOutput(); $this->assertTrue($nodeJsLintOutput->wasStopped()); $this->assertFalse($nodeJsLintOutput->hasTooManyErrors());
Building
