Ich Entwickel gern mit virtualenv und nutzte dabei pip install --editable
I.d.R. hab ich einige 'git' repros unter foo_env/src/
Um alle git repros auf den neusten Stand zu bringen hatte ich erst ein shell Skript und nun das:

Code: Alles auswählen

Aktuelle Version hier: https://github.com/jedie/python-code-sn ... t_repos.py


Im Grunde wird das gemacht:
  • git fetch --all
  • git pull origin master
Wobei immer 'origin' genommen ist, aber 'master' immer durch den aktuellen Branch ersetzt wird.

Nicht schön, aber hilfreich ;)
