Update the i18n_subsites plugin, addresses many issues

Browse Source 
Major highlights
................
- fixed and improved cross-linking (fixes #333) with URLs
  containing e.g. localized month names
  (thanks to issue getpelican/pelican#1198)
- support for custom ``SITEURL`` and ``OUTPUT_PATH`` hierarchy
  (fixes #182)
- sharing of static files (including those of the theme) among
  subsites (fixes #180)

Technical highlights
....................
- added a test suite (works with pelican 3.4)
- translations are installed into Jinja2 environments of all
  generators
- old locale is restored after generation, fixes autoreload

The documentation has been updated and improved (mostly in terms of
formatting).

Known issues
............
- due to the redesign required for correct cross-linking, older
  versions of Pelican (<3.4) are not supported, because they lack
  certain signals
- the ``HIDE_UNTRANSLATED_CONTENT`` setting has been deprecated in
  favor of the ``I18N_UNTRANSLATED_{ARTICLES,PAGES}`` settings which
  offer more control in order to fix #211.
- the test suite works only with pelican 3.4, later versions add a
  timezone field to the date

I18N Sub-sites Plugin
======================
=======================
This plugin extends the translations functionality by creating internationalized sub-sites for the default site. It is therefore redundant with the *\*_LANG_{SAVE_AS,URL}* variables, so it disables them to prevent conflicts.
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. The *\*_LANG_URL* and *\*_LANG_SAVE_AS* variables are set to their normal counterparts (e.g. *ARTICLE_URL*) so they don't conflict with this scheme.
2. While building the site for *DEFAULT_LANG* the translations of pages and articles are not generated, but their relations to the original content is kept via links to them.
3. For each non-default language a "sub-site" with a modified config [#conf]_ is created [#run]_, linking the translations to the originals (if available). The configured language code is appended to the *OUTPUT_PATH* and *SITEURL* of each sub-site. For each sub-site, *DEFAULT_LANG* is changed to the language of the sub-site so that articles in a different language are treated as translations.
If *HIDE_UNTRANSLATED_CONTENT* is True (default), content without a translation for a language is generated as hidden (for pages) or draft (for articles) for the corresponding language sub-site.
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:
.. [#conf] For each language a config override is given in the *I18N_SUBSITES* dictionary.
.. [#run] Using a new *PELICAN_CLASS* instance and its ``run`` method, so each sub-site could even have a different *PELICAN_CLASS* if specified in *I18N_SUBSITES* conf overrides.
- 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 variables overrides dictionary must be given (but can be empty) in the *I18N_SUBSITES* dictionary
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 -> conf_overrides_dict
# mapping: language_code -> settings_overrides_dict
I18N_SUBSITES = {
'cz': {
'SITENAME': 'Hezkej blog',
}
}
- The language code is the language identifier used in the *lang* metadata. It is appended to *OUTPUT_PATH* and *SITEURL* of each I18N sub-site.
- The internationalized config overrides dictionary may specify configuration variable overrides — e.g. a different *LOCALE*, *SITENAME*, *TIMEZONE*, etc. However, it **must not** override *OUTPUT_PATH* and *SITEURL* as they are modified automatically by appending the language code.
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:
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>`_.
- 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>`_.
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:
Additional context variables
............................
main_lang
The language of the top-level site — the original *DEFAULT_LANG*
main_siteurl
The *SITEURL* of the top-level 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.

for example, point to the ``SITEURL`` of each (sub-)site. For this
reason the plugin adds these variables to the template context:
If you don't like the default ordering of the ordered dictionaries, use a Jinja2 filter to alter the ordering.
``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.
This short `howto <./implementing_language_buttons.rst>`_ shows two example implementations of language buttons.
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 woudl 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.
Future plans
============
- add a test suite
- 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'``.
