<h2 id="01localization">01. Localization</h2>
<p>Now that you have your web site in English you start to wonder why there's no Russian version, you're Russian after all!</p>
<p>You set on to create the following <a href="https://github.com/OGStudio/site-pskov-sample/tree/master/02.Language">directory structure</a>:</p>
<ul>
<li><code>cfg</code></li>
<li><code>en/item.template</code></li>
<li><code>en/about.md</code></li>
<li><code>en/cv.md</code></li>
<li><code>ru/item.template</code></li>
<li><code>ru/about.md</code></li>
<li><code>ru/cv.md</code></li>
</ul>
<p>Let's look at the contents of these files closer.</p>
<p><a name="cfg"/></p>
<h2 id="02investigatecfgfile">02. Investigate <code>cfg</code> file</h2>
<p><code>cfg</code> file has the following contents:</p>
<pre><code>input = en;ru
item = item.template
</code></pre>
<p>As you see, <code>input</code> can accept multiple directories separated by <code>;</code> symbol: <strong>PSKOV</strong> will go over each directory specified and run as before.</p>
<p>In this case, both <code>en/</code> and <code>ru/</code> directories have their own <code>item.template</code> file.</p>
<p><a name="item"/></p>
<h2 id="03investigatetemplatefiles">03. Investigate template files</h2>
<ul>
<li><p><code>en/item.template</code> contents:</p>
<pre><code>- - - - Collapsed for brevity - - - -
        &lt;title&gt;Serov&lt;/title&gt;
    &lt;/head&gt;
    &lt;body&gt;
        &lt;div id="header"&gt;
            &lt;strong&gt;Serov&lt;/strong&gt;
            &lt;a href="about.html"&gt;About me&lt;/a&gt;
            &lt;a href="cv.html"&gt;CV&lt;/a&gt;
            &lt;div id="lang"&gt;
                &lt;a href="../en/PSKOV_ITEM_URL"&gt;EN&lt;/a&gt;
                &lt;a href="../ru/PSKOV_ITEM_URL"&gt;RU&lt;/a&gt;
            &lt;/div&gt;
        &lt;/div&gt;
        &lt;center&gt;
- - - - Collapsed for brevity - - - -
</code></pre></li>
<li><p><code>ru/item.template</code> contents:</p>
<pre><code>- - - - Collapsed for brevity - - - -
        &lt;title&gt;Серов&lt;/title&gt;
    &lt;/head&gt;
    &lt;body&gt;
        &lt;div id="header"&gt;
            &lt;strong&gt;Серов&lt;/strong&gt;
            &lt;a href="about.html"&gt;Обо мне&lt;/a&gt;
            &lt;a href="cv.html"&gt;Резюме&lt;/a&gt;
            &lt;div id="lang"&gt;
                &lt;a href="../en/PSKOV_ITEM_URL"&gt;EN&lt;/a&gt;
                &lt;a href="../ru/PSKOV_ITEM_URL"&gt;RU&lt;/a&gt;
            &lt;/div&gt;
        &lt;/div&gt;
        &lt;center&gt;
- - - - Collapsed for brevity - - - -
</code></pre></li>
</ul>
<p><strong>Note</strong>: beginning and ending were collapsed for brevity.</p>
<p>As you can see, both <code>en/item.template</code> and <code>ru/item.template</code> look similar to <code>item.template</code> we saw <a href="education.03.site.html">before</a>.</p>
<p>The changes include:</p>
<ul>
<li>use of <code>&lt;div id="lang"&gt;...&lt;/div&gt;</code> section to present language selection</li>
<li>localization of titles into English and Russian</li>
</ul>
<p>Language selection uses new <strong>PSKOV</strong> constant:</p>
<table>
<thead>
<tr>
<th>PSKOV constant</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td><code>PSKOV_ITEM_URL</code></td>
<td>Provides generated page's file name: <code>&lt;slug&gt;.html</code></td>
</tr>
</tbody>
</table>
<p>As you see, <code>PSKOV_ITEM_URL</code> is all you need to have your page in as many languages as you please.</p>
<p><a name="md"/></p>
<h2 id="04investigatemarkdownfiles">04. Investigate Markdown files</h2>
<p><code>en/about.md</code> and <code>en/cv.md</code> files look almost exactly as <a href="education.03.site.html">before</a>. <code>ru/about.md</code> and <code>ru/cv.md</code> are simply Russian variants of the same pages.</p>
<p>For example, <code>ru/cv.md</code> has the following contents:</p>
<pre><code> Title: Резюме
 Slug: cv

 Здесь вы можете увидеть моё резюме в том случае, если мои произведения всё ещё вас интересуют. Я использовал современный подход ИТ для структурирования своего резюме в виде пар ключ-значение словаря (карты). Наслаждайтесь!

 | Ключ | Значение |
 |---|---|
 | Имя | Валентин Серов |
 | Возраст | 46 |

 | Звания | * академик ИАХ (1898) &lt;br&gt; * действительный член ИАХ (1903) |
</code></pre>
<p><strong>Note</strong>: Russian page has exactly the same <code>Slug:</code> value as English one.</p>

<h2 id="05launchlfsaandgeneratethesite">05. Launch LFSA and generate the site</h2>
<p>Launch <a href="http://opengamestudio.org/lfsa">LFSA</a> so that it points to directory with the files we just observed:</p>
<pre><code>$ /path/to/lfsa-201905.py /path/to/dir/02.Language
</code></pre>
<p>Generate the site:</p>
<ul>
<li>Go to <a href="http://opengamestudio.org/pskov">Tool</a> page</li>
<li>Press <code>Generate</code> button</li>
<li>Open generated <code>en/about.html</code> or <code>ru/about.html</code> from the site's directory locally</li>
<li>Switch language to verify language selection works fine</li>
</ul>
