Thank you, Yury. Looks like your lines are already in FAQ. At least I couldn't find reasonable way to update any chapter.
Thing look clear in theory. However I cannot go on in practice. How to launch any test for micronumpy in interactive mode? I suppose it should be possible to import some modules from micronumpy using interactive mode of pypy. I check out branch release-4.0.x, then ~/work/pypy/pypy_src$ python pypy/bin/pyinteractive.py --allworkingmodules -c "import pypy.module.micronumpy.MultiArrayModule" I complains about signal module and fails. The same happens when I use python 2.7 and pypy 4.0.1 for launching pyinteractive. The same for module micronumpy.ctor. Whole output is here: https://gist.github.com/serge-m/d3f9f9863e15fc5c6af2 What am I doing wrong? In general I want to run a test for micronumpy. Then make it debuggable to see how micronumpy works. I also tried to use pytest and test. I extracted a single test from pypy/pypy_src/pypy/module/micronumpy/test/test_selection.py into test_selection_2.py to make things faster. Output is here: https://gist.github.com/serge-m/3c51f35c702cc57b00c2 On Sun, Jan 3, 2016 at 8:19 AM, Yury V.
