Kind of funny to read this. Before doing a lot of Python packaging, I
was doing some PHP PEAR packaging. There as well, they forced the users
to use "pear install" instead of apt / dpkg. There as well, they were
writing stuff in their README about how to use PEAR. I suppose we have
lots of this kind of occurrence all over the place in Debian (Piotr, you
mentioned Ruby, it must be a good example, I guess (I don't know ruby at
all)).
In PHP, having the pear shell tool wasn't a problem, even if you don't
use it (and even if I would recommend against using it). Then Mathieu
Parent wrote pkg-php-tools, and I wrote "debpear" over it, which
automatically transforms a PEAR package into a Debian package. The same
way, I wrote debpypi, so that I don't waste my time writing again and
again the same stuff. Though my debpypi isn't good enough to be
released, I heard Piotr wrote the same kind of tool.
Shouldn't we go the same way, and encourage our users to use a kind of
wrapper around pip, so that they really get a Debian package installed
instead of a "pip install" thing which will mess everything? Piotr,
where is the tool you told me about? Could you share it? I've attached
my stupid script, just as a reference (though please don't tell me it's
not good enough, I know that already).
Cheers,
Thomas
