Hi Steve,
I've been using Python for many years, just hadn't had to deal with an
escape sequence in the command line args. :-) and couldn't find the solution
in the docs.
It is easy to prove my assertion:
import sys
c = sys.argv[1]
print len(c)
print 'Line 1', c, 'Line 2'
Output:
2
Line 1 \n Line 2
The "2" appears to prove *my* assertion that the argument passed by the
shell to your Python program consists of 2 characters, "\\" followed by "n".
Versus:
import sys
c = sys.argv[1]
print len(c)
print 'Line 1', c.decode('string_escape'), 'Line 2'
Output:
2
Line 1
Line 2
As does this.
Agreed, it is much easier on Unix to deal with this, I have not seen a way
to get the XP command interpreter to allow a multiline command line as you
described.
Your solution was exactly what I need. I had an escape sequence entered on
the command line and needed to decode the string so that Python used it as
an escape sequence, in fact the sequence really is part of the output that
the program produces.
In fairness it was Steven Bethard's solution that gave you the solution
you needed. As long as ytour problem is solved, that's fine, and it
appears that you've solved it in a reasonably cross-platform way.
Thanks again for your assistance.
Always happy to help when I can!
regards
Steve
