Sitemap
|
||||
-------
|
||||
|
||||
The plugin generates a sitemap of the blog.
|
||||
It can generates plain text sitemaps or XML sitemaps.
|
||||
|
||||
Configuration
|
||||
"""""""""""""
|
||||
|
||||
You can use the setting ``SITEMAP`` variable to configure the behavior of the
|
||||
plugin.
|
||||
|
||||
The ``SITEMAP`` variable must be a Python dictionary, it can contain tree keys:
|
||||
|
||||
|
||||
- ``format``, which set the output format of the plugin (``xml`` or ``txt``)
|
||||
|
||||
- ``priorities``, which is a dictionary with three keys:
|
||||
|
||||
- ``articles``, the priority for the URLs of the articles and their
|
||||
translations
|
||||
|
||||
- ``pages``, the priority for the URLs of the static pages
|
||||
|
||||
- ``indexes``, the priority for the URLs of the index pages, such as tags,
|
||||
author pages, categories indexes, archives, etc...
|
||||
|
||||
All the values of this dictionary must be decimal numbers between ``0`` and ``1``.
|
||||
|
||||
- ``changefreqs``, which is a dictionary with three items:
|
||||
|
||||
- ``articles``, the update frequency of the articles
|
||||
|
||||
- ``pages``, the update frequency of the pages
|
||||
|
||||
- ``indexes``, the update frequency of the index pages
|
||||
|
||||
An valid value is ``always``, ``hourly``, ``daily``, ``weekly``, ``monthly``,
|
||||
``yearly`` or ``never``.
|
||||
|
||||
|
||||
If a key is missing or a value is incorrect, it will be replaced with the
|
||||
default value.
|
||||
|
||||
The sitemap is saved in ``<output_path>/sitemap.<format>``.
|
||||
|
||||
.. note::
|
||||
``priorities`` and ``changefreqs`` are informations for search engines.
|
||||
They are only used in the XML sitemaps.

||||
