[QGIS-Developer] etc/ini/python-core.bat

[VOLPES-EXT, Jacky]

Hi Jürgen,

OK I understand.
But as a result it could be considered to update the documentation just before this section here :
https://github.com/qgis/QGIS-Documentation/blob/master/source/docs/pyqgis_developer_cookbook/plugins/ide_debugging.rst#debugging-using-eclipse-and-pydev
which gives the following as an example of script to prepare Eclipse development environment for plugins (now in Python 3):

	call "C:\OSGeo4W\bin\o4w_env.bat"
	set PATH=%PATH%;C:\path\to\your\qgis_core.dll\parent\folder
	C:\path\to\your\eclipse.exe

This does not call py3_env.bat
I guess it would be sufficient to add just this line to the example after the call to o4w_env.bat :

	call "C:\OSGeo4W\bin\ py3_env.bat"

Thanks for you quick answer,
What do you think ?

You need to call py3_env.bat - like everything else in OSGeo4W that uses python3.

python2 is still the default python, although the last bit that was using
python2 - read GRASS - was upgraded to python3 a few days ago.
