I would like to find out how I can launch an independent Python
program from existing one in a cross-platform way. The result I am
after is that a new terminal window should open (for io independent of
the original script).
The following seems to work correctly under Ubuntu and Windows ... but
I haven't been able to find a way to make it work under Mac OS.
Forgot to add that there was an import as follows:
import os # should have been obvious
from subprocess import Popen # slightly less so
def exec_external(code, path):
"""execute code in an external process
currently works under:
* Windows NT (tested)
* GNOME (tested) [January 2nd and 15th change untested]
This also needs to be implemented for OS X, KDE
and some form of linux fallback (xterm?)
"""
if os.name == 'nt':
current_dir = os.getcwd()
target_dir, fname = os.path.split(path)
filename = open(path, 'w')
filename.write(code)
filename.close()
if os.name == 'nt':
os.chdir(target_dir) # change dir so as to deal with paths
that
# include spaces
Popen(["cmd.exe", ('/c start python %s'%fname)])
os.chdir(current_dir)
elif os.name == 'posix':
try:
os.spawnlp(os.P_NOWAIT, 'gnome-terminal', 'gnome- terminal',
'-x', 'python', '%s'%path)
except:
raise NotImplementedError
else:
raise NotImplementedError
==========================
Any help would be greatly appreciated.
