Hi all,
(Catching up). Do people deploy ocitysmap/maposmatic with their
private/own stylesheet? Or do they use what we are providing in
ocitysmap? If we assume that stylesheets are nicely integrated with
ocitysmap and that most people will be happy with them, I believe we
should 1/ ship them all with ocitysmap, 2/ go away from using
configuration files to declare them and register them in a more pythonic
way.
For example, if we assume we ship them all in ocitysmap2/stylesheet,
then IMHO it's enough to add a __init__.py file in the stylesheet
subdirs (eg. maposmatic-printable/) with something like:
import os
import ocitysmap2
class MaposmaticPrintableStyleSheet(ocitysmap2.Stylesheet):
def __init__(self):
ocitysmap2.Stylesheet.__init__(self)
self.name = _('maposmatic printable stulesheet')
self.path = os.path.join(os.path.dirname(__file__), 'osm.xml')
self.description = _('blah')
....etc...
And then, in ocitysmap2/stylesheet/__init__.py:
import ocitysmap2
import ocitysmap2.stylesheet.maposmatic_printable as MP
import ocitysmap2.stylesheet.pierre_orange as PO
# default stylesheet comes first
ocitysmap2.register_stylesheet(MP.MaposmaticPrintableStylesheet())
ocitysmap2.register_stylesheet(PO.PierreOrangeStylesheet())
....etc...
And people who want to have their own stylesheet can easily add the glue
code in ocitysmap2/stylesheet. They also can send us the patch so that
we integrate them.
Of course, it means we should add the default stylesheet there (and
rename the dirs with underscores instead of hyphens).
Regards,
