This is a brief description of whats included.</p> <p>Files to help integration are available <a class="reference external" href="https://github.com/mitsuhiko/jinja2/tree/master/ext">here.</a></p> <div class="section" id="babel-integration"> <span id="id1"></span><h2>Babel Integration<a class="headerlink" href="#babel-integration" title="Permalink to this headline">¶</a></h2> <p>Jinja provides support for extracting gettext messages from templates via a <a class="reference external" href="http://babel.edgewall.org/">Babel</a> extractor entry point called <cite>jinja2.ext.babel_extract</cite>. The Babel support is implemented as part of the <a class="reference internal" href="extensions.html#i18n-extension"><em>i18n Extension</em></a> extension.</p> <p>Gettext messages extracted from both <cite>trans</cite> tags and code expressions.</p> <p>To extract gettext messages from templates, the project needs a Jinja2 section in its Babel extraction method <a class="reference external" href="http://babel.edgewall.org/wiki/Documentation/messages.html#extraction-method-mapping-and-configuration">mapping file</a>:</p> <div class="highlight-ini"><div class="highlight"><pre><span class="k">[jinja2: **/templates/**.html]</span> <span class="na">encoding</span> <span class="o">=</span> <span class="s">utf-8</span> </pre></div> </div> <p>The syntax related options of the <tt class="xref py py-class docutils literal"><span class="pre">Environment</span></tt> are also available as configuration values in the mapping file. For example to tell the extraction that templates use <tt class="docutils literal"><span class="pre">%</span></tt> as <cite>line_statement_prefix</cite> you can use this code:</p> <div class="highlight-ini"><div class="highlight"><pre><span class="k">[jinja2: **/templates/**.html]</span> <span class="na">encoding</span> <span class="o">=</span> <span class="s">utf-8</span> <span class="na">line_statement_prefix</span> <span class="o">=</span> <span class="s">%</span> </pre></div> </div> <p><a class="reference internal" href="extensions.html#jinja-extensions"><em>Extensions</em></a> may also be defined by passing a comma separated list of import paths as <cite>extensions</cite> value. The i18n extension is added automatically.</p> <p class="versionchanged"> <span class="versionmodified">Changed in version 2.7.</span></p> </div> <div class="section" id="pylons"> <h2>Pylons<a class="headerlink" href="#pylons" title="Permalink to this headline">¶</a></h2> <p>With <a class="reference external" href="http://www.pylonshq.com/">Pylons</a> 0.9.7 onwards it’s incredible easy to integrate Jinja into a Pylons powered application.</p> <p>The template engine is configured in <cite>config/environment.py</cite>. The configuration for Jinja2 looks something like that:</p> <div class="highlight-python"><div class="highlight"><pre><span class="kn">from</span> <span class="nn">jinja2</span> <span class="kn">import</span> <span class="n">Environment</span><span class="p">,</span> <span class="n">PackageLoader</span> <span class="n">config</span><span class="p">[</span><span class="s">'pylons.app_globals'</span><span class="p">]</span><span class="o">.</span><span class="n">jinja_env</span> <span class="o">=</span> <span class="n">Environment</span><span class="p">(</span> <span class="n">loader</span><span class="o">=</span><span class="n">PackageLoader</span><span class="p">(</span><span class="s">'yourapplication'</span><span class="p">,</span> <span class="s">'templates'</span><span class="p">)</span> <span class="p">)</span> </pre></div> </div> <p>After that you can render Jinja templates by using the <cite>render_jinja</cite> function from the <cite>pylons.templating</cite> module.</p> <p>Additionally it’s a good idea to set the Pylons’ <cite>c</cite> object into strict mode. Per default any attribute to not existing attributes on the <cite>c</cite> object return an empty string and not an undefined object. To change this just use this snippet and add it into your <cite>config/environment.py</cite>:</p> <div class="highlight-python"><div class="highlight"><pre><span class="n">config</span><span class="p">[</span><span class="s">'pylons.strict_c'</span><span class="p">]</span> <span class="o">=</span> <span class="bp">True</span> </pre></div> </div> </div> <div class="section" id="textmate"> <h2>TextMate<a class="headerlink" href="#textmate" title="Permalink to this headline">¶</a></h2> <p>Inside the <cite>ext</cite> folder at the root of the Jinja2 project there is a bundle for TextMate that supports syntax highlighting for Jinja1 and Jinja2 for text based templates as well as HTML. It also contains a few often used snippets.</p> </div> <div class="section" id="vim"> <h2>Vim<a class="headerlink" href="#vim" title="Permalink to this headline">¶</a></h2> <p>A syntax plugin for <a class="reference external" href="http://www.vim.org/">Vim</a> exists in the Vim-scripts directory as well as the <cite>ext</cite> folder at the root of the Jinja2 project. <a class="reference external" href="http://www.vim.org/scripts/script.php?script_id=1856">The script</a> supports Jinja1 and Jinja2.
