[Jython-dev] pip-related option -J-Dcpython_cmd

[Jeff A. <ja...@fa...>]

HI Stefan:

I'm rationalising the Jython main program and the options parser, and 
I'm looking at the code added by this change:

https://hg.python.org/jython/rev/03f4808038f8#l3.8

which is clearly a work-around you seemed to intend be resolved another 
way eventually. It deals as a specific case with the 
option-J-Dcpython_cmd=python, which ends up as a Jython argument when 
using pip with --global-options. (That's if I've understood correctly.) 
Am I right in thinking this is a specific case of a general problem when 
Java options mix with Python ones (observed here in 2.7.1):

PS startup2> jython -E -J-Dtest=TEST
Unknown option: J-Dtest=TEST
usage: ...

Since that time, and with an unconnected motive, I've changed the 
Windows launcher so that it shuffles recognisable Python options and 
Java options (-J<stuff>) to their proper places. 
(https://hg.python.org/jython/rev/b556dcdf8258) In the tip now, I get:

PS jython-trunk> dist\bin\jython -E -J-Dtest=TEST -c "import sys; print sys.registry.getProperty('test')"
TEST

Do you think this means I can I safely omit the special case from the 
options parser?

Jeff
