The subset can also be set with ``configure``, but the local parameter overrides the option if set. +Returns an object with the following properties: + +* ``language``: detected language +* ``relevance``: integer value +* ``value``: HTML string with highlighting markup +* ``second_best``: object with the same structure for second-best heuristically detected language, may be absent + + +``fixMarkup(value)`` +-------------------- + +Post-processing of the highlighted markup. Currently consists of replacing indentation TAB characters and using ``<br>`` tags instead of new-line characters. Options are set globally with ``configure``. + +Accepts a string with the highlighted markup. + + +``highlightBlock(block)`` +------------------------- + +Applies highlighting to a DOM node containing code. + +This function is the one to use to apply highlighting dynamically after page load +or within initialization code of third-party Javascript frameworks. + +The function uses language detection by default but you can specify the language +in the ``class`` attribute of the DOM node. See the :doc:`class reference +</css-classes-reference>` for all available language names and aliases. + + +``configure(options)`` +---------------------- + +Configures global options: + +* ``tabReplace``: a string used to replace TAB characters in indentation. +* ``useBR``: a flag to generate ``<br>`` tags instead of new-line characters in the output, useful when code is marked up using a non-``<pre>`` container. +* ``classPrefix``: a string prefix added before class names in the generated markup, used for backwards compatibility with stylesheets. +* ``languages``: an array of language names and aliases restricting auto detection to only these languages. + +Accepts an object representing options with the values to updated. Other options don't change +:: + + hljs.configure({ + tabReplace: ' ', // 4 spaces + classPrefix: '' // don't append class prefix + // … other options aren't changed + }) + hljs.initHighlighting(); + + +``initHighlighting()`` +---------------------- + +Applies highlighting to all ``<pre><code>..</code></pre>`` blocks on a page. + + + +``initHighlightingOnLoad()`` +---------------------------- + +Attaches highlighting to the page load event. + + +``registerLanguage(name, language)`` +------------------------------------ + +Adds new language to the library under the specified name. Used mostly internally. + +* ``name``: a string with the name of the language being registered +* ``language``: a function that returns an object which represents the + language definition. The function is passed the ``hljs`` object to be able + to use common regular expressions defined within it. + + +``listLanguages()`` +---------------------------- + +Returns the languages names list. + + + +.. _getLanguage: + + +``getLanguage(name)`` +--------------------- + +Looks up a language by name or alias. + +Returns the language object if found, ``undefined`` otherwise. |
