| <h1>Pedantic</h1> |
| <h2>Configuration</h2> |
| <p> |
| The 'Pedantic' filter is enabled by specifying: |
| <dl> |
| <dt>Apache:<dd><pre class="prettyprint" |
| >ModPagespeedEnableFilters pedantic</pre> |
| <dt>Nginx:<dd><pre class="prettyprint" |
| >pagespeed EnableFilters pedantic;</pre> |
| </dl> |
| <p> |
| in the configuration file. |
| |
| <h2>Description</h2> |
| <p> |
| The 'Pedantic' filter is used to make PageSpeed more HTML4 compliant. Some |
| filters remove type attributes in style and script tags, which are |
| required for HTML4 validation checks but not HTML5. This filter adds default |
| types to script and style tags. Note that it will increase HTML size and thus |
| possibly increase latency so use it only if you require HTML4 validation. |
| </p> |
| |
| <h2>Operation</h2> |
| <p> |
| There are two cases where a <code>type</code> attribute can be added. First, if |
| a <code><style></code> tag does not have a <code>type</code> attribute |
| then a <code>type="text/css"</code> attribute will be added to |
| the <code>style</code> tag. Second, if a <code><script></code> tag does |
| not have a <code>type</code> attribute then |
| a <code>type="text/javascript"</code> attribute will be added to |
| the <code>script</code> tag. |
| </p> |
| <p> |
| The expected method of using the pedantic filter is via a query parameter |
| such as: '<code>?ModPagespeedFilters=+pedantic</code>'. |
| </p> |
| <p> |
| You can see the filter in action at <code>www.modpagespeed.com</code> on |
| this <a |
| href="https://www.modpagespeed.com/examples/pedantic.html?ModPagespeed=on&ModPagespeedFilters=pedantic" |
| >example</a>. |
| </p> |
| |
| <h2>Requirements</h2> |
| <p> |
| The 'Pedantic' filter will not alter a page with an HTML5 DOCTYPE. |
| </p> |
| |
| <h2>Risks</h2> |
| <p> |
| This filter is considered medium risk. It is safe for most pages, but could |
| possibly break scripts by adding <code>text/javascript</code> to a tag if the |
| default mime type is something other than <code>text/javascript</code>. |
