They don't affect the compiled <code>.mo</code> file or app behavior.</p> </div> <h4 id="initialize-a-message-catalog-for-a-locale">Initialize a message catalog for a locale<a class="headerlink" href="#initialize-a-message-catalog-for-a-locale" title="Permanent link">¶</a></h4> <p>The second step is to initialize the catalog for the specific locale of your choice. These locales are the keys of the <code>I18N_LANGUAGES</code> configuration variable. For example, for <em>German</em> would be:</p> <div class="highlight"><pre><span></span><code><span class="c1"># invenio.cfg file</span> <span class="na">I18N_LANGUAGES</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s">[</span> <span class="w"> </span><span class="na">('de', _('German')),</span> <span class="na">]</span> </code></pre></div> <div class="highlight"><pre><span></span><code>invenio-cli<span class="w"> </span>translations<span class="w"> </span>init<span class="w"> </span>-l<span class="w"> </span>de </code></pre></div> <p>Running this command will produce the corresponding <code>.po</code> files:</p> <div class="highlight"><pre><span></span><code>/translations |- babel.ini |- messages.pot |- de/LC_MESSAGES |- messages.po </code></pre></div> <h4 id="compile-the-catalogs">Compile the catalogs<a class="headerlink" href="#compile-the-catalogs" title="Permanent link">¶</a></h4> <p>Finally, you need to compile the catalogs. That can be achieved with the <code>translations</code> command. However, this process is also a part of the <em>setup</em> process so it will be executed when running <code>invenio-cli services setup</code> (or its containerized counter part).</p> <div class="highlight"><pre><span></span><code>invenio-cli<span class="w"> </span>translations<span class="w"> </span>compile </code></pre></div> <p>Running this command will produce the corresponding <code>.mo</code> files:</p> <div class="highlight"><pre><span></span><code>/translations |- babel.ini |- messages.pot |- de/LC_MESSAGES |- messages.po |- messages.mo </code></pre></div> </article> </div> <script>var target=document.getElementById(location.hash.slice(1));target&&target.name&&(target.checked=target.name.startsWith("__tabbed_"))</script> </div> </main> <footer class="md-footer"> <nav class="md-footer__inner md-grid" aria-label="Footer" > <a href="../../topics/administration_panel/" class="md-footer__link md-footer__link--prev" aria-label="Previous: Administration panel"> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M20 11v2H8l5.5 5.5-1.42 1.42L4.16 12l7.92-7.92L13.5 5.5 8 11z"/></svg> </div> <div class="md-footer__title"> <span class="md-footer__direction"> Previous </span> <div class="md-ellipsis"> Administration panel </div> </div> </a> <a href="../custom_fields/" class="md-footer__link md-footer__link--next" aria-label="Next: Create a new custom field"> <div class="md-footer__title"> <span class="md-footer__direction"> Next </span> <div class="md-ellipsis"> Create a new custom field </div> </div> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M4 11v2h12l-5.5 5.5 1.42 1.42L19.84 12l-7.92-7.92L10.5 5.5 16 11z"/></svg> </div> </a> </nav> <div class="md-footer-meta md-typeset"> <div class="md-footer-meta__inner md-grid"> <div class="md-copyright"> <div class="md-copyright__highlight"> Copyright © 2019-2024 CERN, Northwestern University and contributors. </div> Made with <a href="https://squidfunk.github.io/mkdocs-material/" target="_blank" rel="noopener"> Material for MkDocs </a> </div> <div class="md-social"> <a href="https://github.com/inveniosoftware" target="_blank" rel="noopener" title="github.com" class="md-social__link"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 496 512"><path d="M165.9 397.4c0 2-2.3 3.6-5.2 3.6-3.3.3-5.6-1.3-5.6-3.6 0-2 2.3-3.6 5.2-3.6 3-.3 5.6 1.3 5.6 3.6m-31.1-4.5c-.7 2 1.3 4.3 4.3 4.9 2.6 1 5.6 0 6.2-2s-1.3-4.3-4.3-5.2c-2.6-.7-5.5.3-6.2 2.3m44.2-1.7c-2.9.7-4.9 2.6-4.6 4.9.3 2 2.9 3.3 5.9 2.6 2.9-.7 4.9-2.6 4.6-4.6-.3-1.9-3-3.2-5.9-2.9M244.8 8C106.1 8 0 113.3 0 252c0 110.9 69.8 205.8 169.5 239.2 12.8 2.3 17.3-5.6 17.3-12.1 0-6.2-.3-40.4-.3-61.4 0 0-70 15-84.7-29.8 0 0-11.4-29.1-27.8-36.6 0 0-22.9-15.7 1.6-15.4 0 0 24.9 2 38.6 25.8 21.9 38.6 58.6 27.5 72.9 20.9 2.3-16 8.8-27.1 16-33.7-55.9-6.2-112.3-14.3-112.3-110.5 0-27.5 7.6-41.3 23.6-58.9-2.6-6.5-11.1-33.3 2.6-67.9 20.9-6.5 69 27 69 27 20-5.6 41.5-8.5 62.8-8.5s42.8 2.9 62.8 8.5c0 0 48.1-33.6 69-27 13.7 34.7 5.2 61.4 2.6 67.9 16 17.7 25.8 31.5 25.8 58.9 0 96.5-58.9 104.2-114.8 110.5 9.2 7.9 17 22.9 17 46.4 0 33.7-.3 75.4-.3 83.6 0 6.5 4.6 14.4 17.3 12.1C428.2 457.8 496 362.9 496 252 496 113.3 383.5 8 244.8 8M97.2 352.9c-1.3 1-1 3.3.7 5.2 1.6 1.6 3.9 2.3 5.2 1 1.3-1 1-3.3-.7-5.2-1.6-1.6-3.9-2.3-5.2-1m-10.8-8.1c-.7 1.3.3 2.9 2.3 3.9 1.6 1 3.6.7 4.3-.7.7-1.3-.3-2.9-2.3-3.9-2-.6-3.6-.3-4.3.7m32.4 35.6c-1.6 1.3-1 4.3 1.3 6.2 2.3 2.3 5.2 2.6 6.5 1 1.3-1.3.7-4.3-1.3-6.2-2.2-2.3-5.2-2.6-6.5-1m-11.4-14.7c-1.6 1-1.6 3.6 0 5.9s4.3 3.3 5.6 2.3c1.6-1.3 1.6-3.9 0-6.2-1.4-2.3-4-3.3-5.6-2"/></svg> </a> </div> </div> </div> </footer> </div> <div class="md-dialog" data-md-component="dialog"> <div class="md-dialog__inner md-typeset"></div> </div> <script id="__config" type="application/json">{"base": "../../..", "features": ["navigation.tabs", "navigation.footer", "content.code.copy"], "search": "../../../assets/javascripts/workers/search.6ce7567c.min.js", "translations": {"clipboard.copied": "Copied to clipboard", "clipboard.copy": "Copy to clipboard", "search.result.more.one": "1 more on this page", "search.result.more.other": "# more on this page", "search.result.none": "No matching documents", "search.result.one": "1 matching document", "search.result.other": "# matching documents", "search.result.placeholder": "Type to start searching", "search.result.term.missing": "Missing", "select.version": "Select version"}}</script> <script src="../../../assets/javascripts/bundle.83f73b43.min.js"></script> </body> </html>
