What is it?


Jekyll is very powerful. It is very conveniect to write bolg with Jekyll.

If we write mainly in English, and sometimes in other languages, now we can do this in a easy way.

Name rule

THe default language:

  • Page: $page_name.$ext. For example: index.md, about.md.

  • Post: _posts/$dir_pre/$date-$post_name.$ext. For example: _posts/blog/2014-02-26-hi.md.

The other language, short as $lang, put $lang and a dot . after $page_name or $post_name

  • Page: page_name.$lang.$ext, for example:

    index.md => index.cn.md

  • Post: _posts/$dir_pre/$date-$post_name.$ext

    2014-02-26.hi.md => 2014-02-26-hi.cn.md

Build result

  • The default language will build into destination directory as usually, _site, for example.

  • The other language (mark as: $lang), will build into the subdirectory /$lang in the destination directory.

    For example: _site/$lang. If the $lang is en, will be built into _site/en.

Data

  • You can create a data file in the directory _data, for example: i18n.yaml:

    en:
        previous_page: Previous
        next_page:    Next
    
    cn:
        previous_page: 上一页
        next_page:    下一页
    
  • Then use the language variables in pagination.html:

    <li>
    <a href="{{ paginator.previous_page_path }}" aria-label="Previous">
        <span>{{ site.data.i18n[page.language].previous_page }}</span>
    </a>
    </li>
    

Paginate

This plugin enables that we can write blog in multiple languages easily, it also enables that we can use any files that end with differents extensions.


The template

  • Page named index.* is the paginate template for default language, no limited to index.html.

    For example: index.md, index.html.

  • Page named index.$lang.$ext is the paginate template for the other languages(short for $lang).

    For example: index.cn.md, index.html.
