Hi Erik,
no options. As an example of the errors I get let's consider the ticket I am
working on (#21254).
I installed pylint via
$ sage -pip install pylint
my sage install is in /opt/sage so
$ /opt/sage/local/bin/pylint
/opt/sage/src/sage/algebras/cluster_algebra.py | grep E: | head
No config file found, using default configuration
E:327, 0: No name 'morphism' in module 'sage.categories'
(no-name-in-module)
E:335, 0: No name 'constructor' in module 'sage.matrix'
(no-name-in-module)
E:337, 0: No name 'cachefunc' in module 'sage.misc' (no-name-in-module)
E:338, 0: No name 'misc_c' in module 'sage.misc' (no-name-in-module)
E:339, 0: No name 'free_module_element' in module 'sage.modules'
(no-name-in-module)
E:341, 0: No name 'integer' in module 'sage.rings' (no-name-in-module)
E:342, 0: No name 'integer_ring' in module 'sage.rings'
(no-name-in-module)
E:347, 0: No name 'element_wrapper' in module 'sage.structure'
(no-name-in-module)
E:348, 0: No name 'parent' in module 'sage.structure'
(no-name-in-module)
E:349, 0: No name 'sage_object' in module 'sage.structure'
(no-name-in-module)
I get many more warnings about lines being too long, having too many/too few
methods etc but I do not care about those.
Something weird: line 326 and 327 are
from sage.categories.homset import Hom
from sage.categories.morphism import SetMorphism
pylint complains only about the second.
Best

Hi,
I thought this was a question for sage-devel because it is about tickets I
am currently working on (#21254 specifically). Sorry for the wrong
assumption.
I did try sage -pip install pylint before posting but the results were
identical (even launching it from within sage -sh)
That sounds suspicious, though I admit I haven't tried it myself yet.
With what options did you run pylint? If it installed correctly into
Sage's Python it should work.
I wouldn't mind getting that working myself. It would be very nice to
see what cleanup pylint can suggest (though a foolish consistency is
the hobgoblin of little minds--I suspect pylint will require a lot of
exceptions for sage :)

Hi,
note that https://ask.sagemath.org is a nice place to ask such questions
that are not related to sage development but still interesting.
Anyway, Sage uses its own Python install, so you should install pylint
within Sage and import it from there.
A priori, the following should work:
sage -pip install pylint
If you really want to use the pylint from your distro, you should add the
path to your distro's '/${WHATEVER}/python2.7/dist-packages' directory to
Sage's PYTHONPATH, at your own risks.
Ciao,
Thierry

Dear all,
I am trying to use pylint to validate some of the code in a patch I wrote
for sage and, unsurprisingly, I am getting several complaints because my
system-wide pylint can't resolve modules like sage.something.
What is the correct way of doing this? Is there any other alternative to
pylint that I should use instead?
Thanks
S.
