Adds multi-theme support using the new THEMES setting.
You can specify all the themes that you will be using in python
dicionary form. You can then inherit from the themes specified
in THEMES using the corresponding key in the dictionary.
This change partially addresses issue #1019, by teaching Pelican to distinguish
between static files and content source files. A user can now safely add the
same directory to both STATIC_PATHS and PAGE_PATHS (or ARTICLE_PATHS). Pelican
will then process the content source files in that directory normally, and
treat the remaining files as static, without copying the raw content source
files to the output directory. (The OUTPUT_SOURCES setting still works.)
In other words, images and markdown/reST files can now safely live together.
To keep those files together in the generated site, STATIC_SAVE_AS and
PAGE_SAVE_AS (or ARTICLE_SAVE_AS) should point to the same output directory.
There are two new configuration settings:
STATIC_EXCLUDES=[] # This works just like PAGE_EXCLUDES and ARTICLE_EXCLUDES.
STATIC_EXCLUDE_SOURCES=True # Set this to False to get the old behavior.
Two small but noteworthy internal changes:
StaticGenerator now runs after all the other generators. This allows it to see
which files are meant to be processed by other generators, and avoid them.
Generators now include files that they fail to process (e.g. those with missing
mandatory metadata) along with all the other paths in context['filenames'].
This allows such files to be excluded from StaticGenerator's file list, so they
won't end up accidentally published. Since these files have no Content object,
their value in context['filenames'] is None. The code that uses that dict has
been updated accordingly.
Old system was using manual string formatting for log messages.
This caused issues with common operations like exception logging
because often they need to be handled differently for Py2/Py3
compatibility. In order to unify the effort:
- All logging is changed to `logging.level(msg, arg1, arg2)` style.
- A `SafeLogger` is implemented to auto-decode exceptions properly
in the args (ref #1403).
- Custom formatters were overriding useful logging functionality
like traceback outputing (ref #1402). They are refactored to be
more transparent. Traceback information is provided in `--debug`
mode for `read_file` errors in generators.
- Formatters will now auto-format multiline log messages in order
to make them look related. Similarly, traceback will be formatted in
the same fashion.
- `pelican.log.LimitFilter` was (ab)using logging message which
would result in awkward syntax for argumented logging style. This
functionality is moved to `extra` keyword argument.
- Levels for errors that would result skipping a file (`read_file`)
changed from `warning` to `error` in order to make them stand out
among other logs.
- Small consistency changes to log messages (i.e. changing all
to start with an uppercase letter) and quality-of-life improvements
(some log messages were dumping raw object information).
CACHE_PATH can now be relative to settings file like OUTPUT_PATH.
Also add --cache-path commandline option.
Change cache loading warning to a less scary and more helpful message.
This is a reworked and improved version of content caching.
Notable changes:
- by default only raw content and metadata returned by readers are
cached which should prevent conficts with plugins, the speed benefit
of content objects caching is not very big with a simple setup
- renamed --full-rebuild to --ignore-cache
- added more elaborate logging to caching code
Drop duplicates logs.
Allow for logs to be grouped, enforcing a maximum number of logs per group.
Add the LOG_FILTER setting to ask from the configuration file to ignore some
logs (of level up to warning).
`get_instance()` returns two values. Old code, instead of unpacking two
values in two variables, placed the tuple in a single variable
`pelican`.
Later in the same block when `pelican.run()` was called, it resulted in
error.
```

Either the returned value should be unpacked properly or
`pelican[0].run` should be called.
Add a `Readers` class which contains a dict of file extensions / `Reader`
instances. This dict can be overwritten with a `READERS` settings, for instance
to avoid processing *.html files:
READERS = {'html': None}
Or to add a custom reader for the `foo` extension:
READERS = {'foo': FooReader}
This dict is no storing the Reader classes as it was done before with
`EXTENSIONS`. It stores the instances of the Reader classes to avoid instancing
for each file reading.
If DELETE_OUTPUT_DIRECTORY is set to True, all files and directories are
deleted from the output directory. There are, however, several reasons
one might want to retain certain files/directories and avoid their
deletion from the output directory. One such use case is version control
system data: a versioned output directory can facilitate deployment via
Heroku and/or allow the user to easily revert to a prior version of the
site without having to rely on regeneration via Pelican.
This change introduces the OUTPUT_RETENTION setting, a tuple of
filenames that will be preserved when the clean_output_dir function in
pelican.utils is run. Setting OUTPUT_RETENTION = (".hg", ".git") would,
for example, prevent the relevant VCS data from being deleted when the
output directory is cleaned.
If a setting exists in DEFAULT_CONFIG, assume it will be there
(instead of checking and/or providing a local default). The earlier
code was split between the two idioms, which was confusing.
Python generates certain exception messages (like IOError) in system
language, if locale is set. This ensures that the message is properly
converted to unicode in Python 2.
