Blender and pycharm

Question

I'm trying to configure pycharm so it can autocomplete blender python. When searching the web, I only found a solution to autocomplete bge. This was done using preconfigurated files though. Is there a way I can get this to work?

Debug error when running refresh_python_api.bat:

Here is a tutorial I used and it worked for me. How to Set Up PyCharm for Blender — Râistlìn Majere, Apr 3 '15 at 3:16
@BertVdB yes. I have followed the tutorial on Windows with no success though. But then again, it was my first time compiling C code so it might be a beginners mistake. — Nathan, Jun 27 '16 at 1:41

I found that the script mentioned by neowitch had some shortcomings (the fact that data and context were assigned at the top of bpy.py made pycharm sad), so I made a modified version:

https://github.com/mutantbob/pycharm-blender

Unfortunately, right now it does not offer pre-dumped API stubs. You'll have to run it either from the command line, or from a text buffer inside blender. Github isn't really set up to offer pre-built packages (which is essentially what a precomputed set would be).

Also, there are a couple of techniques for getting the generated python into the namespace of your pycharm that I consider better than copying into Python's Lib folder

add the python_api/pypredef folder to the Project Structure as another source root.
add they python_api/pypredef folder to the interpreter's library set (a little trickier, but makes it work in all pycharm projects)

$\begingroup$ I'm sorry, but I do not understand where your script is better than the original... When I run your refresh_python it gives an error... $\endgroup$ – Bert VdB May 26 '17 at 19:36
$\begingroup$ It worked on my linux laptop. If you're using windows run it from a text buffer inside blender, or you can read the shell script to learn the command-line invocation. If there's some other sort of error, i can not troubleshoot the error without knowing what the error is. $\endgroup$ – Mutant Bob May 30 '17 at 21:26
$\begingroup$ When I run this script inside blender, blender crashes... $\endgroup$ – Bert VdB May 31 '17 at 8:49

$\begingroup$ I'm having the same problem as @BertVdB. I downloaded the script and invoked Blender 2.78 to run it (on Windows). It works for a few seconds then fails with Error: Not freed memory blocks: 124, total unfreed memory 0.030273 MB. The last line it printed before that is updating: mathutils.py. The script did generate a bunch of Python files in a pypredef/ subdirectory but I have no idea if they're complete. $\endgroup$ – François Beaune Jul 28 '17 at 18:13

Download pydev-blender.zip from http://airplanes3d.net/pydev-000_e.xml

Quoted from ba:

unzip into Blender folder(where blender.exe is).
go into doc folder and run refresh_python_api.bat.
go into doc\python_api\pypredef folder and change all extensions to .py instead of pypredef.
cut or copy contents of pypredef folder to you Python's Lib folder.*

Be warned, that zip is from some time between 2011 and 2013. It's all Blender 2.5 and I cannot say if or what changes have been made since then.

*EDIT: After working with pycharm for a while, I strongly recommend Mutant Bob's method of adding the generated python file folder to either the Interpreter or the Project Structure instead of copying them to the Python Lib!

$\begingroup$ This doesn't work correctly for me. I configured an interpreter path to look up the pypredef folder, but PyCharm still doesn't know about bpy.props for example. I tried adding the single files instead of the folder, but they disappeared after restarting PyCharm. I just have import bpy at the top of a python module, then try to use it like bpy.props.BoolProperty(...). Any ideas? $\endgroup$ – Ray Jul 19 '16 at 19:29
$\begingroup$ I had the same problem when I started working with the blender interface and it is still something I haven't found a perfect solution for tbh. Some time ago I found this definition: github.com/nazodane/pydev_predef I'm using both this and the definition above in conjunction. That seems to cover everything. Download the repository, In PyCharm-installation-folder/bin locate idea.properties, open with nodepad and change idea.max.intellisense.filesize to 999999 (99999 works just fine too) Then add the predev folder to your project via Project Structure > Add Content Root $\endgroup$ – neowitch Jul 20 '16 at 14:51
$\begingroup$ That sounds like a better solution, but it's a shame the defs don't contain bpy.context and bpy.data =( I wish there would be just autocompletion files shipped with Blender itself... $\endgroup$ – Ray Jul 20 '16 at 16:34
