=======================
I18N Sub-sites Plugin
=======================
This plugin extends the translations functionality by creating
internationalized sub-sites for the default site.
This plugin is designed for Pelican 3.4 and later.
What it does
============
1. When the content of the main site is being generated, the settings
are saved and the generation stops when content is ready to be
written. While reading source files and generating content objects,
the output queue is modified in certain ways:
- translations that will appear as native in a different (sub-)site
will be removed
- untranslated articles will be transformed to drafts if
``I18N_UNTRANSLATED_ARTICLES`` is ``'hide'`` (default), removed if
``'remove'`` or kept as they are if ``'keep'``.
- untranslated pages will be transformed into hidden pages if
``I18N_UNTRANSLATED_PAGES`` is ``'hide'`` (default), removed if
``'remove'`` or kept as they are if ``'keep'``.''
- additional content manipulation similar to articles and pages can
be specified for custom generators in the ``I18N_GENERATOR_INFO``
setting.
2. For each language specified in the ``I18N_SUBSITES`` dictionary the
settings overrides are applied to the settings from the main site
and a new sub-site is generated in the same way as with the main
site until content is ready to be written.
3. When all (sub-)sites are waiting for content writing, all removed
contents, translations and static files are interlinked across the
(sub-)sites.
4. Finally, all the output is written.
Setting it up
=============
For each extra used language code, a language-specific settings overrides
dictionary must be given (but can be empty) in the ``I18N_SUBSITES`` dictionary
.. code-block:: python
PLUGINS = ['i18n_subsites', ...]
# mapping: language_code -> settings_overrides_dict
I18N_SUBSITES = {
'cz': {
'SITENAME': 'Hezkej blog',
}
}
You must also have the following in your pelican configuration
.. code-block:: python
JINJA_ENVIRONMENT = {
'extensions': ['jinja2.ext.i18n'],
}
Default and special overrides
-----------------------------
The settings overrides may contain arbitrary settings, however, there
are some that are handled in a special way:
``SITEURL``
Any overrides to this setting should ensure that there is some level
of hierarchy between all (sub-)sites, because Pelican makes all URLs
relative to ``SITEURL`` and the plugin can only cross-link between
the sites using this hierarchy. For instance, with the main site
``http://example.com`` a sub-site ``http://example.com/de`` will
work, but ``http://de.example.com`` will not. If not overridden, the
language code (the language identifier used in the ``lang``
metadata) is appended to the main ``SITEURL`` for each sub-site.
``OUTPUT_PATH``, ``CACHE_PATH``
If not overridden, the language code is appended as with ``SITEURL``.
Separate cache paths are required as parser results depend on the locale.
``STATIC_PATHS``, ``THEME_STATIC_PATHS``
If not overridden, they are set to ``[]`` and all links to static
files are cross-linked to the main site.
``THEME``, ``THEME_STATIC_DIR``
If overridden, the logic with ``THEME_STATIC_PATHS`` does not apply.
``DEFAULT_LANG``
This should not be overridden as the plugin changes it to the
language code of each sub-site to change what is perceived as translations.
Localizing templates
--------------------
Most importantly, this plugin can use localized templates for each
sub-site. There are two approaches to having the templates localized:
- You can set a different ``THEME`` override for each language in
``I18N_SUBSITES``, e.g. by making a copy of a theme ``my_theme`` to
``my_theme_lang`` and then editing the templates in the new
localized theme. This approach means you don't have to deal with
gettext ``*.po`` files, but it is harder to maintain over time.
- You use only one theme and localize the templates using the
`jinja2.ext.i18n Jinja2 extension
<http://jinja.pocoo.org/docs/templates/#i18n>`_. For a kickstart
read this `guide <./localizing_using_jinja2.rst>`_.
Additional context variables
............................
It may be convenient to add language buttons to your theme in addition
to the translation links of articles and pages. These buttons could,
for example, point to the ``SITEURL`` of each (sub-)site. For this
reason the plugin adds these variables to the template context:
``main_lang``
The language of the main site — the original ``DEFAULT_LANG``
``main_siteurl``
The ``SITEURL`` of the main site — the original ``SITEURL``
``lang_siteurls``
An ordered dictionary, mapping all used languages to their
``SITEURL``. The ``main_lang`` is the first key with ``main_siteurl``
as the value. This dictionary is useful for implementing global
language buttons that show the language of the currently viewed
(sub-)site too.
``extra_siteurls``
An ordered dictionary, subset of ``lang_siteurls``, the current
``DEFAULT_LANG`` of the rendered (sub-)site is not included, so for
each (sub-)site ``set(extra_siteurls) == set(lang_siteurls) -
set([DEFAULT_LANG])``. This dictionary is useful for implementing
global language buttons that do not show the current language.
``relpath_to_site``
A function that returns a relative path from the first (sub-)site to
the second (sub-)site where the (sub-)sites are identified by the
language codes given as two arguments.
If you don't like the default ordering of the ordered dictionaries,
use a Jinja2 filter to alter the ordering.
All the siteurls above are always absolute even in the case of
``RELATIVE_URLS == True`` (it would be to complicated to replicate the
Pelican internals for local siteurls), so you may rather use something
like ``{{ SITEURL }}/{{ relpath_to_site(DEFAULT_LANG, main_lang }}``
to link to the main site.
This short `howto <./implementing_language_buttons.rst>`_ shows two
example implementations of language buttons.
Usage notes
===========
- It is **mandatory** to specify ``lang`` metadata for each article
and page as ``DEFAULT_LANG`` is later changed for each sub-site, so
content without ``lang`` metadata would be rendered in every
(sub-)site.
- As with the original translations functionality, ``slug`` metadata
is used to group translations. It is therefore often convenient to
compensate for this by overriding the content URL (which defaults to
slug) using the ``url`` and ``save_as`` metadata. You could also
give articles e.g. ``name`` metadata and use it in ``ARTICLE_URL =
'{name}.html'``.
Development
===========
- A demo and a test site is in the ``gh-pages`` branch and can be seen
at http://smartass101.github.io/pelican-plugins/

-----------------------------
Implementing language buttons
-----------------------------
Each article with translations has translations links, but that's the
only way to switch between language subsites.
For this reason it is convenient to add language buttons to the top
menu bar to make it simple to switch between the language subsites on
all pages.
Example designs
---------------
Language buttons showing other available languages
..................................................
The ``extra_siteurls`` dictionary is a mapping of all other (not the
``DEFAULT_LANG`` of the current (sub-)site) languages to the
``SITEURL`` of the respective (sub-)sites
.. code-block:: jinja
<!-- SNIP -->
<nav><ul>
{% if extra_siteurls %}
{% for lang, url in extra_siteurls.items() %}
<li><a href="{{ url }}/">{{ lang }}</a></li>
{% endfor %}
<!-- separator -->
<li style="background-color: white; padding: 5px;">&nbsp</li>
{% endif %}
{% for title, link in MENUITEMS %}
<!-- SNIP -->
Notice the slash ``/`` after ``{{ url }}``, this makes sure it works
with local development when ``SITEURL == ''``.
Language buttons showing all available languages, current is active
...................................................................
The ``lang_subsites`` dictionary is a mapping of all languages to the
``SITEURL`` of the respective (sub-)sites. This template sets the
language of the current (sub-)site as active.
.. code-block:: jinja
<!-- SNIP -->
<nav><ul>
{% if lang_siteurls %}
{% for lang, url in lang_siteurls.items() %}
<li{% if lang == DEFAULT_LANG %} class="active"{% endif %}><a href="{{ url }}/">{{ lang }}</a></li>
{% endfor %}
<!-- separator -->
<li style="background-color: white; padding: 5px;">&nbsp</li>
{% endif %}
{% for title, link in MENUITEMS %}
<!-- SNIP -->
Tips and tricks
---------------
Showing more than language codes
................................
If you want the language buttons to show e.g. the names of the
languages or flags [#flags]_, not just the language codes, you can use
a jinja filter to translate the language codes
.. code-block:: python
languages_lookup = {
'en': 'English',
'cz': 'Čeština',
}
def lookup_lang_name(lang_code):
return languages_lookup[lang_code]
JINJA_FILTERS = {
...
'lookup_lang_name': lookup_lang_name,
}
And then the link content becomes
.. code-block:: jinja
<!-- SNIP -->
{% for lang, siteurl in lang_siteurls.items() %}
<li{% if lang == DEFAULT_LANG %} class="active"{% endif %}><a href="{{ siteurl }}/">{{ lang | lookup_lang_name }}</a></li>
{% endfor %}
<!-- SNIP -->
Changing the order of language buttons
......................................
Because ``lang_siteurls`` and ``extra_siteurls`` are instances of
``OrderedDict`` with ``main_lang`` being always the first key, you can
change the order through a jinja filter.
.. code-block:: python
def my_ordered_items(ordered_dict):
items = list(ordered_dict.items())
# swap first and last using tuple unpacking
items[0], items[-1] = items[-1], items[0]
return items
JINJA_FILTERS = {
...
'my_ordered_items': my_ordered_items,
}
And then the ``for`` loop line in the template becomes
.. code-block:: jinja
<!-- SNIP -->
{% for lang, siteurl in lang_siteurls | my_ordered_items %}
<!-- SNIP -->
.. [#flags] Although it may look nice, `w3 discourages it
<http://www.w3.org/TR/i18n-html-tech-lang/#ri20040808.173208643>`_.

-----------------------------
Localizing themes with Jinja2
-----------------------------
1. Localize templates
---------------------
To enable the |ext| extension in your templates, you must add it to
``JINJA_ENVIRONMENT`` in your Pelican configuration
.. code-block:: python
JINJA_ENVIRONMENT = {
'extensions': ['jinja2.ext.i18n', ...]
}
Then follow the `Jinja2 templating documentation for the I18N plugin
<http://jinja.pocoo.org/docs/templates/#i18n>`_ to make your templates
localizable. This usually means surrounding strings with the ``{%
trans %}`` directive or using ``gettext()`` in expressions
.. code-block:: jinja
{% trans %}translatable content{% endtrans %}
{{ gettext('a translatable string') }}
For pluralization support, etc. consult the documentation.
To enable `newstyle gettext calls
<http://jinja.pocoo.org/docs/extensions/#newstyle-gettext>`_ the
``I18N_GETTEXT_NEWSTYLE`` config variable must be set to ``True``
(default).
.. |ext| replace:: ``jinja2.ext.i18n``
2. Specify translations location
--------------------------------
The |ext| extension uses the `Python gettext library
<http://docs.python.org/library/gettext.html>`_ for translating
strings.
In your Pelican config you can give the path in which to look for
translations in the ``I18N_GETTEXT_LOCALEDIR`` variable. If not given,
it is assumed to be the ``translations`` subfolder in the top folder
of the theme specified by ``THEME``.
The domain of the translations (the name of each translation file is
``domain.mo``) is controlled by the ``I18N_GETTEXT_DOMAIN`` config
variable (defaults to ``messages``).
Example
.......
With the following in your Pelican settings file
.. code-block:: python
I18N_GETTEXT_LOCALEDIR = 'some/path/'
I18N_GETTEXT_DOMAIN = 'my_domain'
the translation for language 'cz' will be expected to be in
``some/path/cz/LC_MESSAGES/my_domain.mo``
3. Extract translatable strings and translate them
--------------------------------------------------
There are many ways to extract translatable strings and create
``gettext`` compatible translations. You can create the ``*.po`` and
``*.mo`` message catalog files yourself, or you can use some helper
tool as described in `the Python gettext library tutorial
<http://docs.python.org/library/gettext.html#internationalizing-your-programs-and-modules>`_.
You of course don't need to provide a translation for the language in
which the templates are written which is assumed to be the original
``DEFAULT_LANG``. This can be overridden in the
``I18N_TEMPLATES_LANG`` variable.
Recommended tool: babel
.......................
`Babel <http://babel.pocoo.org/>`_ makes it easy to extract
translatable strings from the localized Jinja2 templates and assists
with creating translations as documented in this `Jinja2-Babel
tutorial
<http://pythonhosted.org/Flask-Babel/#translating-applications>`_
[#flask]_ on which the following is based.
1. Add babel mapping
~~~~~~~~~~~~~~~~~~~~
Let's assume that you are localizing a theme in ``themes/my_theme/``
and that you use the default settings, i.e. the default domain
``messages`` and will put the translations in the ``translations``
subdirectory of the theme directory as
``themes/my_theme/translations/``.
It is up to you where to store babel mappings and translation files
templates (``*.pot``), but a convenient place is to put them in
``themes/my_theme/`` and work in that directory. From now on let's
assume that it will be our current working directory (CWD).
To tell babel to extract translatable strings from the templates
create a mapping file ``babel.cfg`` with the following line
.. code-block:: cfg
[jinja2: templates/**.html]
2. Extract translatable strings from templates
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Run the following command to create a ``messages.pot`` message catalog
template file from extracted translatable strings
.. code-block:: bash
pybabel extract --mapping babel.cfg --output messages.pot ./
3. Initialize message catalogs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you want to translate the template to language ``lang``, run the
following command to create a message catalog
``translations/lang/LC_MESSAGES/messages.po`` using the template
``messages.pot``
.. code-block:: bash
pybabel init --input-file messages.pot --output-dir translations/ --locale lang --domain messages
babel expects ``lang`` to be a valid locale identifier, so if e.g. you
are translating for language ``cz`` but the corresponding locale is
``cs``, you have to use the locale identifier. Nevertheless, the
gettext infrastructure should later correctly find the locale for a
given language.
4. Fill the message catalogs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The message catalog files format is quite intuitive, it is fully
documented in the `GNU gettext manual
<http://www.gnu.org/software/gettext/manual/gettext.html#PO-Files>`_. Essentially,
you fill in the ``msgstr`` strings
.. code-block:: po
msgid "just a simple string"
msgstr "jenom jednoduchý řetězec"
msgid ""
"some multiline string"
"looks like this"
msgstr ""
"nějaký více řádkový řetězec"
"vypadá takto"
You might also want to remove ``#,fuzzy`` flags once the translation
is complete and reviewed to show that it can be compiled.
5. Compile the message catalogs
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The message catalogs must be compiled into binary format using this
command
.. code-block:: bash
pybabel compile --directory translations/ --domain messages
This command might complain about "fuzzy" translations, which means
you should review the translations and once done, remove the fuzzy
flag line.
(6.) Update the catalogs when templates change
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you add any translatable patterns into your templates, you have to
update your message catalogs too. First you extract a new message
catalog template as described in the 2. step. Then you run the
following command [#pybabel_error]_
.. code-block:: bash
pybabel update --input-file messages.pot --output-dir translations/ --domain messages
This will merge the new patterns with the old ones. Once you review
and fill them, you have to recompile them as described in the 5. step.
.. [#flask] Although the tutorial is focused on Flask-based web
applications, the linked translation tutorial is not
Flask-specific.
.. [#pybabel_error] If you get an error ``TypeError: must be str, not
bytes`` with Python 3.3, it is likely you are
suffering from this `bug
<https://github.com/mitsuhiko/flask-babel/issues/43>`_.
Until the fix is released, you can use babel with
Python 2.7.

Series plugin
-------------
**NOTE:** [This plugin has been moved to its own repository](https://github.com/pelican-plugins/series). Please file any issues/PRs there. Once all plugins have been migrated to the [new Pelican Plugins organization](https://github.com/pelican-plugins), this monolithic repository will be archived.
The series plugin allows you to join different posts into a series.
In order to mark posts as part of a series, use the `:series:` metadata:
:series: NAME_OF_THIS_SERIES
or, in Markdown syntax
Series: NAME_OF_THIS_SERIES
The plugin collects all articles belonging to the same series and provides
series-related variables that you can use in your template.
#### Indexing
By default articles in a series are ordered by date and then automatically numbered.
If you want to force a given order just specify the `:series_index:` metadata or in Markdown `series_index:`,
starting from 1. All articles with this enforced index are put at the beginning of
the series and ordered according to the index itself. All the remaining articles
come after them, ordered by date.
The plugin provides the following variables to your templates
* `article.series.name` is the name of the series as specified in the article metadata
* `article.series.index` is the index of the current article inside the series
* `article.series.all` is an ordered list of all articles in the series (including the current one)
* `article.series.all_previous` is an ordered list of the articles published before the current one
* `article.series.all_next` is an ordered list of the articles published after the current one
* `article.series.previous` is the previous article in the series (a shortcut to `article.series.all_previous[-1]`)
* `article.series.next` is the next article in the series (a shortcut to `article.series.all_next[0]`)
For example:
{% if article.series %}
<p>This post is part {{ article.series.index }} of the "{{ article.series.name }}" series:</p>
<ol class="parts">
{% for part_article in article.series.all %}
<li {% if part_article == article %}class="active"{% endif %}>
<a href='{{ SITEURL }}/{{ part_article.url }}'>{{ part_article.title }}</a>
</li>
{% endfor %}
</ol>
{% endif %}

# Subcategory Plugin
This plugin adds support for subcategories in addition to article categories.
Subcategories are hierarchical. Each subcategory has a parent, which is either a regular category or another subcategory.
Feeds can be generated for each subcategory, just like categories and tags.
## Usage
### Metadata
Subcategories are an extension to categories. Add subcategories to an article's category metadata using a `/` like this:
```
Category: Regular Category/Sub-Category/Sub-Sub-category
```
Then create a `subcategory.html` template in your theme, similar to the `category.html` or `tag.html` templates.
In your templates, `article.category` continues to act the same way. Your subcategories are stored in the `articles.subcategories` list. To create breadcrumb-style navigation you might try something like this:
```
<nav class="breadcrumb">
<ol>
<li>
<a href="{{ SITEURL }}/{{ article.category.url }}">{{ article.category}}</a>
</li>
{% for subcategory in article.subcategories %}
<li>
<a href="{{ SITEURL }}/{{ subcategory.url }}">{{ subcategory.shortname }}</a>
</li>
{% endfor %}
</ol>
</nav>
```
### Subcategory folders
To specify subcategories using folders you can configure `PATH_METADATA`<br>
to extract the article path (containing all category and subcategory folders) into the `subcategory_path` metadata. The following settings would use all available subcategories for the hierarchy:
```
PATH_METADATA= '(?P<subcategory_path>.*)/.*'
```
You can limit the depth of generated subcategories by adjusting the regular expression to only include a specific number of path separators (`/`). For example, the following would generate only a single level of subcategories regardless of the folder tree depth:
```
PATH_METADATA= '(?P<subcategory_path>[^/]*/[^/]*)/.*'
```
## Subcategory Names
Each subcategory's full name is a `/`-separated list of it parents and itself. This is necessary to keep each subcategory unique. It means you can have `Category 1/Foo` and `Category 2/Foo` and they won't interfere with each other. Each subcategory has an attribute `shortname` which is just the name without its parents associated. For example if you had...
```
Category/Sub Category1/Sub Category2
```
... the full name for Sub Category2 would be `Category/Sub Category1/Sub Category2` and the "short name" would be `Sub Category2`.
If you need to use the slug, it is generated from the short name -- not the full name.
## Settings
Consistent with the default settings for Tags and Categories, the default settings for subcategories are:
```
'SUBCATEGORY_SAVE_AS' = os.path.join('subcategory', '{savepath}.html')
'SUBCATEGORY_URL' = 'subcategory/(fullurl).html'
```
`savepath` and `fullurl` are generated recursively, using slugs. So the full URL would be:
```
category-slug/sub-category-slug/sub-sub-category-slug
```
... with `savepath` being similar but joined using `os.path.join`.
Similarly, you can save subcategory feeds by adding one of the following to your Pelican configuration file:
```
SUBCATEGORY_FEED_ATOM = 'feeds/%s.atom.xml'
SUBCATEGORY_FEED_RSS = 'feeds/%s.rss.xml'
```
... and this will create a feed with `fullurl` of the subcategory. For example:
```
feeds/category/subcategory.atom.xml
```
Article urls can also use the values of `subpath` and `suburl` in their definitions. These are equivalent to the `fullurl` and `savepath` of the most specific subcategory. If you have articles that don't have subcategories these values are set to the category slug.
```
ARTICLE_SAVE_AS = os.path.join('{subpath}' 'articles' '{slug}.html')
ARTICLE_URL = '{suburl}/articles/{slug}.html'
```

tag_cloud
=========
**NOTE:** `This plugin has been moved to its own repository <https://github.com/pelican-plugins/tag-cloud>`_. Please file any issues/PRs there. Once all plugins have been migrated to the `new Pelican Plugins organization <https://github.com/pelican-plugins>`_, this monolithic repository will be archived.
This plugin generates a tag-cloud.
Installation
------------
In order to use to use this plugin, you have to edit(*) or create(+) the following files::
blog/
├── pelicanconf.py *
├── content
├── plugins +
│ └── tag_cloud.py +
└── themes
└── mytheme
├── templates
│ └── base.html *
└── static
└── css
└── style.css *
In **pelicanconf.py** you have to activate the plugin::
PLUGIN_PATHS = ["plugins"]
PLUGINS = ["tag_cloud"]
Into your **plugins** folder, you should add tag_cloud.py (from this repository).
In your theme files, you should change **base.html** to apply formats (and sizes) defined in **style.css**, as specified in "Settings", below.
Settings
--------
================================================ =====================================================
Setting name (followed by default value) What does it do?
================================================ =====================================================
``TAG_CLOUD_STEPS = 4`` Count of different font sizes in the tag
cloud.
``TAG_CLOUD_MAX_ITEMS = 100`` Maximum number of tags in the cloud.
``TAG_CLOUD_SORTING = 'random'`` The tag cloud ordering scheme. Valid values:
random, alphabetically, alphabetically-rev, size and
size-rev
``TAG_CLOUD_BADGE = True`` Optionnal setting : can bring **badges**, which mean
say : display the number of each tags present
on all articles.
================================================ =====================================================
The default theme does not include a tag cloud, but it is pretty easy to add one::
<ul class="tagcloud">
{% for tag in tag_cloud %}
<li class="tag-{{ tag.1 }}">
<a href="{{ SITEURL }}/{{ tag.0.url }}">
{{ tag.0 }}
{% if TAG_CLOUD_BADGE %}
<span class="badge">{{ tag.2 }}</span>
{% endif %}
</a>
</li>
{% endfor %}
</ul>
You should then also define CSS styles with appropriate classes (tag-1 to tag-N,
where N matches ``TAG_CLOUD_STEPS``), tag-1 being the most frequent, and
define a ``ul.tagcloud`` class with appropriate list-style to create the cloud.
You should copy/paste this **badge** CSS rule ``ul.tagcloud .list-group-item <span>.badge``
if you're using ``TAG_CLOUD_BADGE`` setting. (this rule, potentially long , is suggested to avoid
conflicts with CSS libs as twitter Bootstrap)
For example::
ul.tagcloud {
list-style: none;
padding: 0;
}
ul.tagcloud li {
display: inline-block;
}
li.tag-1 {
font-size: 150%;
}
li.tag-2 {
font-size: 120%;
}
/* ... add li.tag-3 etc, as much as needed */
ul.tagcloud .list-group-item span.badge {
background-color: grey;
color: white;
}
By default the tags in the cloud are sorted randomly, but if you prefers to have it alphabetically use the `alphabetically` (ascending) and `alphabetically-rev` (descending). Also is possible to sort the tags by it's size (number of articles with this specific tag) using the values `size` (ascending) and `size-rev` (descending).
