feat: add basic theme system

Browse source

to allow testing of Vue 3 + Oruga, to eventually replace Vue 2 + Buefy
as the default theme.

def get_available_themes(config):
"""
Returns the official list of theme names which are available for
use in the app. Privileged users may choose among these when
changing the global theme.
If config specifies a list, that will be honored. Otherwise the
default list is: ``['default', 'butterfly']``
Note that the 'default' theme is Vue 2 + Buefy, while 'butterfly'
is Vue 3 + Oruga.
You can specify via config by setting e.g.:
.. code-block:: ini
[wuttaweb]
themes.keys = default, butterfly, my-other-one

Validate and return the "effective" theme.
If caller specifies a ``theme`` then it will be returned (if
"available" - see below).
Otherwise the current theme will be read from db setting. (Note
we do not read simply from config object, we always read from db
setting - this allows for the theme setting to change dynamically
while app is running.)
In either case if the theme is not listed in
:func:`get_available_themes()` then a ``ValueError`` is raised.

that happens in :func:`get_effective_theme()`, which this function
will call first.
Once we have the valid theme name, we check config in case it
specifies a template path override for it. But if not, a default
template path is assumed.
The default path would be expected to live under
``wuttaweb:templates/themes``; for instance the ``butterfly``
theme has a default template path of
``wuttaweb:templates/themes/butterfly``.
