[Python-de] Entrypoint Spezifikation : String oder Dict und wie beides?

[Dr. Volker Jaenisch]

Servus Python Freaks!

Zuerst die schlechte Nachricht. Setup-Tools speichert die Entrypoints in
den Egg-Infos ab. Das ist an sich ja nicht verkehrt. Aber es erzeugt
unnötige Fehler, weil setup-tools offenbar auch die schon erzeugten
entrypoints.txt Dateien parsed.

Erzeuge ein neues VEnv.
$ mkvirtualenv test321

Die setup.py im VEnv
# -*- coding: utf-8 -*-

Geht schief.

Anpassen der setup.py:
...
    ],
    extras_require={
        'test': [
        ],
    },
    entry_points={
       'console_scripts' : ['bokeh_server =
inqbus.bokeh_plone.bokeh.startup:startup_bokeh'],
    }
)

Erneutes installieren:
python setup.py install
...

    _setup_distribution = dist = klass(attrs)

Suche nach Dateien die z3c.autoinstall beinhalten

(test321) volker at runner:~/workspace/test321/inqbus.plone_bokeh$ grep -R

Löschen der Dateien
Erst das Löschen von
../lib/python2.7/site-packages/inqbus.plone_bokeh-1.0a1-py2.7.egg/EGG-INFO/entry_points.txt:
ermöglichte, das die setup.py sauber geparsed wurde.

Das ist IMHO ein Fehler in Setup-Tools. Was in die Egg-Info geschrieben
wurde darf nicht das erneute Ausführen der setup.py behindern.


Beste Grüße
