python - Installing dependencies of debian/control file -


i in process of porting ruby file used in our build system python. file looks depends lines in debian/control file in our repository, checks every dependency, , apt-get installs isn't installed. trying reproduce functionality.

as part of porting python, looked @ deb_pkg_tools module. pip installed , created simple script, install-dep2.py.

#!/usr/bin/python import deb_pkg_tools  controldict = deb_pkg_tools.control.load_control_file('debian/control')

however, when run script, following error:

$ build/bin/install-dep2.py traceback (most recent call last):   file "build/bin/install-dep2.py", line 4, in <module>     controldict = deb_pkg_tools.control.load_control_file('debian/control') attributeerror: 'module' object has no attribute 'control'

the debian/control file exists:

$ ls -l debian/control -rw-rw-r-- 1 stephen stephen 2532 jul 13 14:28 debian/control

how can process debian/control file? don't need use deb_pkg_tools if there better way.

the problem have not python thinks debian/control not exist, rather seems deb_pkg_tools.control not exist.

i use python-debian package debian parse control file if you. here code parse control file dependencies. should work packages multiple binary packages.

import deb822  paragraph in deb822.deb822.iter_paragraphs(open('debian/control')):     item in paragraph.items():         if item[0] == 'depends':             print item[1]

each item in above example tuple pairs "key" "value", item[0] gives "key" , item[1] gives "value".

obviously above sample prints out dependencies in control file, dependencies aren't in format suitable directly plug apt-get install. also, parsing control file, got stuff ${python:depends} in addition actual package names, have consider. here example of output got above example:

joseph@crunchbang:~$ python test.py    bittornado,  ${python:depends},  python-psutil,  python-qt4,  python-qt4reactor,  python-twisted,  xdg-utils,  ${misc:depends},  ${shlibs:depends}

i found this bug report , python-debian source code quite useful resources when answering question.
