01. Localization

Now that you have your web site in English you start to wonder why there's no Russian version, you're Russian after all!

You set on to create the following directory structure:

cfg
en/item.template
en/about.md
en/cv.md
ru/item.template
ru/about.md
ru/cv.md

Let's look at the contents of these files closer.

02. Investigate `cfg` file

cfg file has the following contents:

input = en;ru
item = item.template

As you see, input can accept multiple directories separated by ; symbol: PSKOV will go over each directory specified and run as before.

In this case, both en/ and ru/ directories have their own item.template file.

03. Investigate template files

en/item.template contents:

- - - - Collapsed for brevity - - - -
        <title>Serov</title>
    </head>
    <body>
        <div id="header">
            <strong>Serov</strong>
            <a href="about.html">About me</a>
            <a href="cv.html">CV</a>
            <div id="lang">
                <a href="../en/PSKOV_ITEM_URL">EN</a>
                <a href="../ru/PSKOV_ITEM_URL">RU</a>
            </div>
        </div>
        <center>
- - - - Collapsed for brevity - - - -

ru/item.template contents:

- - - - Collapsed for brevity - - - -
        <title>Серов</title>
    </head>
    <body>
        <div id="header">
            <strong>Серов</strong>
            <a href="about.html">Обо мне</a>
            <a href="cv.html">Резюме</a>
            <div id="lang">
                <a href="../en/PSKOV_ITEM_URL">EN</a>
                <a href="../ru/PSKOV_ITEM_URL">RU</a>
            </div>
        </div>
        <center>
- - - - Collapsed for brevity - - - -

Note: beginning and ending were collapsed for brevity.

As you can see, both en/item.template and ru/item.template look similar to item.template we saw before.

The changes include:

use of <div id="lang">...</div> section to present language selection
localization of titles into English and Russian

Language selection uses new PSKOV constant:

PSKOV constant	Description
`PSKOV_ITEM_URL`	Provides generated page's file name: `<slug>.html`

As you see, PSKOV_ITEM_URL is all you need to have your page in as many languages as you please.

04. Investigate Markdown files

en/about.md and en/cv.md files look almost exactly as before. ru/about.md and ru/cv.md are simply Russian variants of the same pages.

For example, ru/cv.md has the following contents:

 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 |
 | Семейное положение | Женат |
 | Страна | Российская Империя |
 | Учёба | Императорская Академия художеств |
 | Звания | * академик ИАХ (1898) <br> * действительный член ИАХ (1903) |

Note: Russian page has exactly the same Slug: value as English one.

05. Launch LFSA and generate the site

Launch LFSA so that it points to directory with the files we just observed:

$ /path/to/lfsa-201905.py /path/to/dir/02.Language

Generate the site:

Go to Tool page
Press Generate button
Open generated en/about.html or ru/about.html from the site's directory locally
Switch language to verify language selection works fine
