<paragraph role="paragraph" xml-lang="en-US" id="par_id411585843652556">This service provides a number of methods related to the translation of strings with minimal impact on the program's source code. The methods provided by the <literal>L10N</literal> service can be used mainly to:</paragraph>
<list type="unordered">
<listitem>
<paragraph id="par_id601614351922212" role="listitem">Create POT files that can be used as templates for translation of all strings in the program.</paragraph>
</listitem>
<listitem>
<paragraph id="par_id131614352196513" role="listitem">Get translated strings at runtime for the language defined in the <literal>Locale</literal> property.</paragraph>
</listitem>
</list>
</section>
<note id="par_id971614966420419">The acronym <literal>L10N</literal> stands for Localization and refers to a set of procedures for translating software to a specific country or region.</note>
<paragraph role="paragraph" id="par_id291585843652438" xml-lang="en-US">PO files have long been promoted in the free software community as a means to providing multilingual user interfaces. This is accomplished through the use of human-readable text files with a well defined structure that specifies, for any given language, the source language string and the localized string.</paragraph>
<paragraph role="paragraph" id="par_id181585843652814" xml-lang="en-US">The main advantage of the PO format is dissociation of the programmer and the translator. PO files are independent text files, so the programmer can send POT template files to translators, who will then translate their contents and return the translated PO files for each supported language.</paragraph>
<tip id="par_id811614352321187">The <literal>L10N</literal> service is based on the GNU implementation of PO (portable object) files. To learn more about this file format, visit <link href="https://www.gnu.org/software/gettext/manual/html_node/PO-Files.html" name="GetText">GNU gettext Utilities: PO Files</link>.</tip>
<paragraph role="paragraph" id="par_id91585843652832" xml-lang="en-US">This service implements the methods listed below:</paragraph>
<list type="unordered">
<listitem>
<paragraph id="par_id1158584365237" role="listitem" xml-lang="en-US"><emph>AddText</emph>: Used by the programmer to build a set of strings that will be translated later.</paragraph>
</listitem>
<listitem>
<paragraph id="par_id81637866601151" role="listitem"><emph>AddTextsFromDialog</emph>: Extracts all strings from a <literal>Dialog</literal> service instance.</paragraph>
</listitem>
<listitem>
<paragraph id="par_id681585843652331" role="listitem" xml-lang="en-US"><emph>ExportToPOTFile</emph>: Exports the strings added by the <literal>AddText</literal> method to a POT file.</paragraph>
</listitem>
<listitem>
<paragraph id="par_id531585843652697" role="listitem" xml-lang="en-US"><emph>GetText</emph>: Gets the translated strings at runtime.</paragraph>
</listitem>
</list>
<note id="par_id361614361362393">Note that the first two methods are used to build a set of translatable strings and export them to a POT file. However, it is not mandatory to create POT files using these methods. Since they are text files, the programmer could have created them using any text editor.</note>
