Hi Philipp,
just now I'm trying to use pySim to read a SIM card, but I notice:
ImportError: No module named pytlv.TLV
I can find no pytlv in the debian packaging; and I notice this dependency was
added only recently. When going back to
859e0fd1ce08699930064c12fb9f7908ef972b50 I can use pySim fine without that.
a) I think the readme should hint at dependencies that pySim requires, which
should include pytlv and where to find it.
b) In python, it is easy to import pytlv only in case it is actually used,
which would simplify dependencies for users that don't need to "get file/record
length from FCP (USIM)" -- would that make sense?
What are your thoughts?

Hello Neels,
just now I'm trying to use pySim to read a SIM
card, but I notice:
ImportError: No module named pytlv.TLV
I can find no pytlv in the debian packaging; and I notice this dependency was
added only recently. When going back to
859e0fd1ce08699930064c12fb9f7908ef972b50 I can use pySim fine without that.
Yes, there is no debian package. Those packages have to be installed
using python-pip.
a) I think the readme should hint at dependencies that
pySim requires, which
should include pytlv and where to find it.
I have added pyscard and pytlv notes to the readme but I am not sure if
this is really all.

b) In python, it is easy to import pytlv only in case
it is actually used,
which would simplify dependencies for users that don't need to "get file/record
length from FCP (USIM)" -- would that make sense?
I have tried it out, syomoUSIM-SJS1 currently does not have to look at
card responses.
I have no experience with optional imports, you mean we should do it
like this?

best regards,
Philipp

I really don't think it is a good idea to depend on modules that are not
part of major distributions, not even debian with its tens of thousands of
packages.
So if we can somehow avoid it without reinventing the wheel (maybe there's
an alternative python module that is shipped?), I would try to avoid it.
Regards,
Harald
