This commit adds optional fabfile.py generation during the
pelican-quickstart process. Reasons include:
* "make" is cumbersome to install on Windows
* Fabric runs in any Python environment
* fabfile is just Python and thus more flexible and extensible
This is an initial implementation and does not currently provide as many
upload options as its Makefile counterpart.
Refs #584.
The `slugify()` function used by Pelican is in general very good at
coming up with something both readable and URL-safe. However, there are
a few specific cases where it causes conflicts. One that I've run into
is using the strings `C++` and `C` as tags, both of which transform to
the slug `c`. This commit adds an optional `SLUG_SUBSTITUTIONS` setting
which is a list of 2-tuples of substitutions to be carried out
case-insensitively just prior to stripping out non-alphanumeric
characters. This allows cases like `C++` to be transformed to `CPP` or
similar. This can also improve the readability of slugs.
The documentation doesn't make it very clear how to prevent certain
pages from being generated, such as the Authors, Tags, and Categories
collection pages. This change makes it slightly more obvious how to
prevent these pages from being generated. Fixes#940.
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.
We no longer instantiate the Static object in the StaticGenerator, so
we can't set the save_as argument anymore. If you want to adjust the
output path, use the upcoming EXTRA_PATH_METADATA setting.
Support the forms listed by the W3C [1]. I also removed the
'%Y-%d-%m' form, which can be confused with the '%Y-%m-%d' ISO form.
The new ISO forms can use 'Z' to designate UTC or '[+-]HHMM' to
specify offsets from UTC. Other time zone designators are not
supported.
The '%z' directive has only been supported since Python 3.2 [2], so if
you're running Pelican on Python 2.7, you're stuck with 'Z' for UTC.
Conveniently, we get ValueErrors for both invalid directives and
data/format missmatches, so we don't need special handling for the 2.7
case inside get_date().
