01. Blog

So, you have your web site in both English and Russian. You start to feel the need to regularly share your thoughts with the world as blog posts.

You set on to create the following directory structure:

pskov.cfg
en/blog/
- item.template
- index.template
- preview.template
- pagination.template
- pagination.prev.template
- pagination.next.template
- 1885.md
- 1886.01.md
- 1886.02.md
- 1887.01.md
- 1887.02.md
- 1888.md
- 1896.md
- 1899.md
en/page/
- item.template
- about.md
- cv.md
ru/blog/
- item.template
- index.template
- preview.template
- pagination.template
- pagination.prev.template
- pagination.next.template
- 1885.md
- 1886.01.md
- 1886.02.md
- 1887.01.md
- 1887.02.md
- 1888.md
- 1896.md
- 1899.md
ru/page/
- item.template
- about.md
- cv.md

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

02. Investigate `pskov.cfg` file

pskov.cfg file has the following contents:

input = en/page;ru/page;en/blog;ru/blog
item = item.template
preview = preview.template
index = index.template
paginationPrev = pagination.prev.template
paginationNext = pagination.next.template
paginationPrevNext = pagination.template
previewSize = 200
previewEnding = . . .
previewsPerPage = 3
previewPageBaseName = index

You already met input and item keys. Let's see into new ones:

Key	Description
`preview`	Points to an HTML template that is used to generate HTML preview out of the first `previewSize` (approximately) characters for each Markdown file
`index`	Points to an HTML template that is used to generate preview page to host previews
`paginationPrev`	Points to an HTML template that is used to generate pagination section to navigate backwards
`paginationNext`	Points to an HTML template that is used to generate pagination section to navigate forward
`paginationPrevNext`	Points to an HTML template that is used to generate pagination section
`previewSize`	How many characters (approximately) to take out of a Markdown file to generate a preview
`previewEnding`	String to use at the end of each preview
`previewsPerPage`	Maximum number of previews hosted by a preview page
`previewsPageBaseName`	Base file name for preview pages

In our case:

we restrict previews to 200 characters in size (approximately)
we use . . . string at the end of each preview
preview pages host 3 previews maximum
preview pages are saved as index.html, index2.html, index3.html, etc.

03. Investigate item templates of the blog

en/blog/item.template contents:

- - - - Collapsed for brevity - - - -
<body>
    <div id="header">
        <strong>Serov</strong>
        <a href="../../en/blog/index.html">Blog</a>
        <a href="../../en/page/about.html">About me</a>
        <a href="../../en/page/cv.html">CV</a>
        <div id="lang">
            <a href="../../en/blog/PSKOV_ITEM_URL">EN</a>
            <a href="../../ru/blog/PSKOV_ITEM_URL">RU</a>
        </div>
    </div>
    <center>
        <h1>In the blog...</h1>
        <div class="contents">
            <h2 class="itemTitle">
                <a href="PSKOV_ITEM_URL">PSKOV_ITEM_TITLE</a>
            </h2>
            <p class="itemDate">PSKOV_ITEM_DATE</p>

PSKOV_ITEM_CONTENTS

This sample web site has been generated by PSKOV.

ru/blog/item.template contents:

- - - - Collapsed for brevity - - - -
<body>
    <div id="header">
        <strong>Серов</strong>
        <a href="../../ru/blog/index.html">Блог</a>
        <a href="../../ru/page/about.html">Обо мне</a>
        <a href="../../ru/page/cv.html">Резюме</a>
        <div id="lang">
            <a href="../../en/blog/PSKOV_ITEM_URL">EN</a>
            <a href="../../ru/blog/PSKOV_ITEM_URL">RU</a>
        </div>
    </div>
    <center>
        <h1>В блоге...</h1>
        <div class="contents">
            <h2 class="itemTitle">
                <a href="PSKOV_ITEM_URL">PSKOV_ITEM_TITLE</a>
            </h2>
            <p class="itemDate">PSKOV_ITEM_DATE</p>

PSKOV_ITEM_CONTENTS

Этот пример сайта сгенерирован ПСКОВОМ.

- - - - Collapsed for brevity - - - - ```

Note: beginning and ending were collapsed for brevity.

As you can see, both files look similar to item.template files we saw before.

The changes include:

new URLs to reference pages in page directory and the first preview page in blog directory
title is referenced inside contents section as a link pointing to a complete blog post
date is referenced to highlight relationship among different blog posts in time

Date reference uses new PSKOV_ITEM_DATE constant:

PSKOV constant	Description
`PSKOV_ITEM_DATE`	Value of `Date` key of the page's Markdown file

04. Investigate preview templates

en/blog/preview.template contents:

<div class="contents">
    <h2 class="itemTitle">
        <a href="PSKOV_ITEM_URL">PSKOV_ITEM_TITLE</a>
    </h2>
    <p class="itemDate">PSKOV_ITEM_DATE</p>
PSKOV_PREVIEW
    <div class="itemMore">
        <a href="PSKOV_ITEM_URL">Continue reading</a>
    </div>
</div>

ru/blog/preview.template contents:

<div class="contents">
    <h2 class="itemTitle">
        <a href="PSKOV_ITEM_URL">PSKOV_ITEM_TITLE</a>
    </h2>
    <p class="itemDate">PSKOV_ITEM_DATE</p>
PSKOV_PREVIEW
    <div class="itemMore">
        <a href="PSKOV_ITEM_URL">Читать дальше</a>
    </div>
</div>

Previews have no <head>, <body>, and similar full page HTML tags. Previews represent sections inserted into preview pages.

Preview itself is referenced by PSKOV_PREVIEW constant:

PSKOV constant	Description
`PSKOV_PREVIEW`	Provides contents of a Markdown file limited by `previewSize` characters (approximately)

05. Investigate templates of preview pages

en/blog/index.template contents:

- - - - Collapsed for brevity - - - -
<body>
    <div id="header">
        <strong>Serov</strong>
        <a href="../../en/blog/index.html">Blog</a>

        <a href="../../en/page/cv.html">CV</a>
        <div id="lang">
            <a href="../../en/blog/PSKOV_INDEX_URL">EN</a>
            <a href="../../ru/blog/PSKOV_INDEX_URL">RU</a>
        </div>
    </div>
    <center>
        <h1>Blog</h1>
PSKOV_PREVIEWS
PSKOV_PAGINATION
        <div id="footer">
            This sample web site has been generated by <a href="http://opengamestudio.org/pskov">PSKOV</a>.
        </div>
    </center>
</body>
- - - - Collapsed for brevity - - - -

ru/blog/index.template contents:

        <a href="../../ru/page/cv.html">Резюме</a>
        <div id="lang">

- - - - Collapsed for brevity - - - -

Notes:

beginning and ending were collapsed for brevity
PSKOV_INDEX_URL constant is used to provide language selection

Here are new PSKOV constants explained:

PSKOV constant	Description
`PSKOV_INDEX_URL`	Provides generated preview page file name: `<previewsPageBaseName><id>.html`
`PSKOV_PREVIEWS`	Provides a set of previews
`PSKOV_PAGINATION`	Provides pagination section to navigate preview pages

06. Investigate pagination templates

Pagination templates represent HTML sections to navigate preview pages.

There are free pagination templates:

Pagination template	Description
Previous	A visitor can only go backwards
Next	A visitor can only go forward
Both	A visitor can either go backwards, or forward

Let's look at English pagination templates:

en/blog/pagination.prev.template contents:

<p>Page PSKOV_PAGE_ID of PSKOV_PAGES_COUNT</p>
<p>
    <a href="PSKOV_PREV_PAGE_URL">« Newer</a>
</p>

en/blog/pagination.next.template contents:

<p>Page PSKOV_PAGE_ID of PSKOV_PAGES_COUNT</p>
<p>
    <a href="PSKOV_NEXT_PAGE_URL">Older »</a>
</p>

en/blog/pagination.template contents:

<p>Page PSKOV_PAGE_ID of PSKOV_PAGES_COUNT</p>
<p>
    <a href="PSKOV_PREV_PAGE_URL">« Newer</a>
    <a href="PSKOV_NEXT_PAGE_URL">Older »</a>
</p>

Russian counterparts look similar. Here's ru/blog/pagination.template contents:

<p>Страница PSKOV_PAGE_ID из PSKOV_PAGES_COUNT</p>
<p>
    <a href="PSKOV_PREV_PAGE_URL">« Новее</a>
    <a href="PSKOV_NEXT_PAGE_URL">Старее »</a>
</p>

Here are new PSKOV constants we used:

PSKOV constant	Description
`PSKOV_PAGE_ID`	Provides preview page id starting from `1`
`PSKOV_PAGES_COUNT`	Provides total number of generated preview pages
`PSKOV_PREV_PAGE_URL`	Provides previous preview page file name
`PSKOV_NEXT_PAGE_URL`	Provides next preview page file name

07. Investigate Markdown files

Markdown files represent blog posts and they look almost like Markdown files for pages. Here's en/blog/1885.md contents:

 Title: Bullocks
 Date: 1885
 Slug: 1885.01.bullocks

 ![Bullocks][bullocks]

 I've been painting "Bullocks" sketch while I was staying in Odessa at Kuznetsov's in 1885.

 [bullocks]: https://upload.wikimedia.org/wikipedia/commons/c/cb/Walentin_Aleksandrovich_Serov_Bullocks.jpg

Date is used to sort blog posts by date in descending order:

Header key	Description
`Date`	Provides value for `PSKOV_ITEM_DATE` constant when generating HTML out of Markdown

08. Launch LFSA

ERROR Your browser does not support HTML5 video

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

$ /path/to/lfsa_1.0.0.py /path/to/dir/03.Blog

09. Generate the site

ERROR Your browser does not support HTML5 video

Go to Tool page and press Generate button to generate HTML files right where Markdown ones reside.

10. Observe the site
