  448. <p name="d206" id="d206" class="graf--p">Today, we’re going to look at the powerful new <strong class="markup--strong markup--p-strong">auto-formatting</strong> feature in <a href="http://jscs.info" data-href="http://jscs.info" class="markup--anchor markup--p-anchor" rel="nofollow"><strong class="markup--strong markup--p-strong">JSCS</strong></a> for automatically applying style guide rules in our scripts. This has been <a href="https://github.com/jscs-dev/node-jscs/issues/516" data-href="https://github.com/jscs-dev/node-jscs/issues/516" class="markup--anchor markup--p-anchor" rel="nofollow">in-development</a> for some time and is in my view, a game changer.</p>
  449. <h3 name="61ad" id="61ad" class="graf--h3">JSCS</h3>
  450. <p name="aed0" id="aed0" class="graf--p">In a number of the OSS projects we hack on at Google, we love using JSCS<strong class="markup--strong markup--p-strong"> </strong>for linting JS against rules in our style guide. JSCS excels at catching style issues like mixing spaces and tabs, inconsistent quote marks, trailing whitespace &amp; it can enforce several other <a href="http://jscs.info/rules.html" data-href="http://jscs.info/rules.html" class="markup--anchor markup--p-anchor" rel="nofollow">validation rules</a>.</p>
  451. <p name="3558" id="3558" class="graf--p">For convenience, JSCS includes presets for the <a href="https://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xml" data-href="https://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xml" class="markup--anchor markup--p-anchor" rel="nofollow">Google</a>, <a href="https://github.com/felixge/node-style-guide" data-href="https://github.com/felixge/node-style-guide" class="markup--anchor markup--p-anchor" rel="nofollow">Node</a> and <a href="https://contribute.jquery.org/style-guide/js/" data-href="https://contribute.jquery.org/style-guide/js/" class="markup--anchor markup--p-anchor" rel="nofollow">jQuery</a> style guides, amongst others. This makes setup super convenient. Custom configuration can be applied via a <a href="https://github.com/google/web-starter-kit/blob/master/.jscsrc" data-href="https://github.com/google/web-starter-kit/blob/master/.jscsrc" class="markup--anchor markup--p-anchor" rel="nofollow">.jscsrc</a> file and for the projects I work on we usually only require minimal additional tweaking here.</p>

  476. <p name="ad3d" id="ad3d" class="graf--p">Note: JSCS 1.12.0 includes support for auto-formatting a number of popular rules, including <strong class="markup--strong markup--p-strong">EOF, spacing and indentation validation</strong>. Any augmentation of the AST is not yet supported, however JSCS will eventually support all rules. The other good news is that the internal `token-assert` module makes writing custom autoformatting rules quite trivial.</p>
  477. <p name="67a2" id="67a2" class="graf--p">That said, there are still more rules they would love to support and help is always <a href="http://jscs.info/contributing.html" data-href="http://jscs.info/contributing.html" class="markup--anchor markup--p-anchor" rel="nofollow">welcome</a>. Examples of more specific rules that they are interested in adding include disallowing commas before line breaks and disallowing anonymous functions.</p>

  481. <p name="50d1" id="50d1" class="graf--p graf--last">If you haven’t been using JSCS for style validation, hopefully the idea of <strong class="markup--strong markup--p-strong">automatically formatting your source </strong>will make it sweet enough to try out.
