popen eating quotes?

[Bryan]

i have a batch file that contains these two lines:

-- args.bat

echo %1
echo %2
when i run args.bat from the command line it works correctly... notice that
abc has quotes in the first example and not in the second.

C:\Temp>"c:\pro gram files\test\args " -vv abc
C:\Temp>echo -vv
-vv
C:\Temp>echo abc
abc

C:\Temp>"c:\pro gram files\test\args " -vv "abc"
C:\Temp>echo -vv
-vv
C:\Temp>echo "abc"
"abc"
from python, i'm having trouble getting the quotes around abc to work

import os
def run_args(arg): .... i, o = os.popen4('"c:/program files/test/args.bat" -vv %s' % arg)
.... print o.read()
.... run_args('abc') C:\python\pytho n23\lib\site-packages>echo -vv
-vv
C:\python\pytho n23\lib\site-packages>echo abc
abc
run_args('"abc" ')

'c:/program' is not recognized as an internal or external command,
operable program or batch file.
what is going on here? why does "abc" effect the uoted program name. does
anyone know how to fix this? how to pass a quoted arguments through to
popen? i need to do this because in my real code, i'm passing paths as
arguments and need them quoted.

i'm using python 2.3 on winxp.

thanks,

bryan

This has been discussed before. One such thread that I participated in

This really is a cesspool on Windows, and the fault isn't Python's.
Python is just calling the Windows functions, which insist on behaving
badly compared to the Unix behavior.

thanks for the link, but it didn't help me solve my problem. i just read
many articles posted about popen and windows and there seems to be a
solution to this problem. i need to pass a path to a program using popen so
i can capture the output. since the path and/or file name can have spaces
in it, i need to quote it. what's the way to get around this issue? i saw
it mentioned in several places to try win32pipe.popen , but it had the same
problem as os.popen. so, is this something that cannot be done in python at
all with no work-around? is there another way besides using os.system or
os.popen?

import os
def run_args(arg): .... i, o = os.popen4('"c:/program files/test/args.bat" -vv %s' % arg)
.... print o.read()
.... run_args('"this is a very long path with spaces"')

'c:/program' is not recognized as an internal or external command,
operable program or batch file.

thanks,

Not memorable, but at least shorter, is
<http://groups.google.c om/groups?threadm= 0000161b%40boss ar.com.pl>
In general all you need is the threadm or selm parameter, which
gives the message-id of the post in question; if memory serves,
threadm and selm differ in whether the resulting page shows the
rest of the thread.

(Ignore the selm in your URL above; it's inside the prev
parameter, which stores information about where you were before
arriving at the page the URL is actually for.)

It seems that Google also assigns an id to each thread; with
suitable poking around (see, e.g., the source for the page at the
above URL) you can locate a 'th' parameter which can be used in
place of the threadm/selm parameter if you wish to refer to the
thread as a whole. In your case that's
<http://groups.google.c om/groups?th=77576 209b6262476>
(As this illustrates, the resulting URL is often shorter than one
using the message-id.) The first ten messages in the thread
appear on the page obtained thus, with anchors, so you can refer
to them individually by appending '#link1', '#link2', etc. This
makes nice short URLs too (though I'm not certain that *which*
messages such anchors refer to is constant over time as the thread
grows).

All discovered empirically. Use at your own risk.

I just got the following working where os.getcwd() is returning:

If this dosen't help, then (sound of large hammer being removed
from a tool box) maybe this will:

def g(arg):
x = os.getcwd()
os.chdir( "c:/program files/test/" )
i, o = os.popen4( 'args.bat -vv %s' % arg )
os.chdir( x )
print o.read()

rob,

thanks... this is exactly the solution i came up with too. it does remove
the path, but not the spaces in the file name. i _might_ be able to live
with this hack though.

the code i'm porting to python is from perl, and the perl code doesn't have
the popen issue.

@xxxoutput=`xxx -vv "$file"`;

now i won't be able show how cool python is :(

threadm and selm differ in whether the resulting page shows the
rest of the thread.
Fortunately, the Message-Id: is available in the message itself (it's
part of every NNTP posting), so even without Google you theoretically
have complete information to give the Google Groups URL for any post:

<http://groups.google.c om/groups?threadm= MESSAGE-ID>

for threaded, or

<http://groups.google.c om/groups?selm=MES SAGE-ID>

for the message alone.

Hello Bryan,

run_args('"abc" ')

'c:/program' is not recognized as an internal or external command,
operable program or batch file.

Didn't check but maybe win32api.GetSho rtPath will help.
(Get Mark's excellent package from http://starship.python.net/crew/mhammond/)

HTH.

If all you want is a short URL for posting, have a look at
http://tinyurl.com/

Jeff's *long* URL would then be: http://tinyurl.com/iy1q

I came across this problem too - I got round it by adding the executable directory to the start of my path, then calling just the executable filename:

path = os.getenv("PATH ")
os.putenv("PATH ", r"C:\Program Files\Microsoft Visual Studio .NET\Common7\ID E;" + path)
vsCommand = 'devenv.com /build debug myproj.vcproj'
processHandles = popen2.popen4(v sCommand)
