[Python-apps-team] Bug#880497: pytimechart: missing dependencies

[Antonio Ospite]

Package: pytimechart
Version: 1.0.0~rc1-3.2
Severity: grave
Justification: renders package unusable

Dear Maintainer,

it looks like pytimechart misses some dependencies, and this makes the
package unusable for me.

Here are some examples:

---------------------------------------------------------------------
$ pytimechart 
Traceback (most recent call last):
  File "/usr/bin/pytimechart", line 9, in <module>
    load_entry_point('pytimechart==1.0.0.rc1', 'gui_scripts', 'pytimechart')()
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 564, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 2662, in load_entry_point
    return ep.load()
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 2316, in load
    return self.resolve()
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 2322, in resolve
    module = __import__(self.module_name, fromlist=['__name__'], level=0)
  File "/usr/lib/python2.7/dist-packages/timechart/timechart.py", line 39, in <module>
    from  kiva.fonttools.font_manager import fontManager, FontProperties
  File "/usr/lib/python2.7/dist-packages/kiva/__init__.py", line 21, in <module>
    from fonttools import Font
  File "/usr/lib/python2.7/dist-packages/kiva/fonttools/__init__.py", line 1, in <module>
    from font import Font, str_to_font
  File "/usr/lib/python2.7/dist-packages/kiva/fonttools/font.py", line 11, in <module>
    from .font_manager import FontProperties, fontManager
  File "/usr/lib/python2.7/dist-packages/kiva/fonttools/font_manager.py", line 65, in <module>
    from fontTools.ttLib import TTFont, TTLibError
ImportError: No module named fontTools.ttLib
---------------------------------------------------------------------

The error from above can be fixed by installing the "python-fonttools"
package, so this one should be added as a dependency of the package.

However this is not enough to have a completely usable package, there is
still a missing dependency:

---------------------------------------------------------------------

    format_exception_only(t, v))
ImportError: Unable to import the image backend for the wx toolkit (reason: ['ImportError: No module named kiwisolver\n']).
---------------------------------------------------------------------

The "kiwisolver" dependency is also missing, and it looks like it's not
available in Debian.

A temporary workaround is to install it from pip:

---------------------------------------------------------------------
$ pip install kiwisolver
---------------------------------------------------------------------

After that pytimechart works fine.

Thanks,
   Antonio

P.S. the link in the Homepage field of the package is broken, I think
the current upstream is https://github.com/tardyp/pytimechart
