I have seen the answers you provided, thank you.
Also, I forgot to mention that the generated scripts look like the
following :
#!/usr/bin/python
# EASY-INSTALL-ENTRY-SCRIPT: 'rdflib==4.0.1','console_scripts','csv2rdf'
__requires__ = 'rdflib==4.0.1'
import sys
from pkg_resources import load_entry_point
if __name__ == '__main__':
sys.exit(
load_entry_point('rdflib==4.0.1', 'console_scripts', 'csv2rdf')()
)
... which leads to problems with (recursive) dependencies mentioned in the
.egg-info that may not be satisfied in Debian :-/
And also, the original rdflib/tools/*.py modules don't have a sheebang
on first line, which prevents a direct symlink option from /usr/bin/...
So... after various experiments, I think I'll go this way :
- get rid of these scripts installed through eazy_install
- add a python-rdflib-tools package that contains shell scripts of the
form :
#!/bin/sh
exec /usr/bin/python -m rdflib.tools.csv2rdf $*
- make this package depend on python-rdflib | python3-rdflib
Thus, I hope we have something basic which works in most cases (I hope I
haven't overlooked some details).
I wonder if this would sound reasonable to add a feature to dh-python or
pybuild so that such "conversions" of 'console_scripts' could be done
automatically...
Comments/remarks much welcome.
Best regards,
