Any ideas? I don't think you can do that. Whenever you start an application from the command prompt the title is modified by appending a dash and the name of the program you started. When the application terminates the title is reset (to remove the name of the running program). So any change to the title will only last until the next time CMD.EXE prompts for input. The exception is that any title set using the TITLE command becomes the reset title for that command prompt. I can think of only one way round this, which is to run your python program from a batch file and find some way to pass the desired title back to the batch file where you can set it with the TITLE command. For example, you could write the title to a temporary file, or if your program doesn't produce much other output print it to stdout and parse the program output using a for command: e.g. This sets the title to the current time: C:\FOR /F tokens=* %i in ( More? 'python -c from time import *; print asctime(localtime())' More? ) DO @TITLE %i C:\ Obvious notes: In a batch file you would double the % characters, and you don't type C:\ or More? as these are the prompts from CMD.EXE. Also this won't work on really old versions of CMD.EXE or with COMMAND.COM. -- http://mail.python.org/mailman/listinfo/python-list
Re: Setting win32 console title from Python
Hmm.
From an interactive interpreter this works for me.
import os
os.system('title Jay')
but the title returns to its previous value when I Ctrl-Z out of the
process.
If I save this as a file and run it, it seems to work without spawning
a new window but resets it the title after the program finishes like
above.
import os
os.system('title Jay')
x = raw_input()
You mention that the SetConsoleTitle api resets itself after the script
finishes so I'm assuming that 'title' command is just calling the same
api under the covers.
What is your requirement specifically? I do something similar but in a
different way but it might not be what you are after.
I have a 'projects' directory where I keep all of my work. I have
written a small python script 'p.py' that I call like this
p [s|e|*] projectname
the 's' is for shell
the 'e' is for explorer window
the '*' is for both shell and explorer
If there is only one argument, I assume it is the project name and I
default the other argument to 'e'.
if the projectname doesn't have any wildcard characters, I append a '*'
and glob my project directory with that value. if the glob call only
returns a single value, I go ahead and do what was requested (open a
shell or explorer window to that directory) if there is more than one
value returned, I present a numbered menu of project directories that
match and wait for input on which one to open.
The point to all this, is that when I open a shell from p.py I use this
command.
os.system(r'start %s /D%s\%s' % (proj,directory,proj))
This spawns a new cmd window with the title of my project name.
Spawning the process with the correct name from the beginning seems to
do the trick.
But like I said, I don't really know your exact requirements.
HTH.

What I do today is actually using a .BAT file and read the name from a temp file created by a python script. It works, but it's slow and the batchfile-language gives me the creep ;-) I'll try to find out why it does work in command.exe/WConio though. -- http://mail.python.org/mailman/listinfo/python-list
Re: Setting win32 console title from Python
Hi Jay. It seems like my requirement is a light edition of your. I like having many console windows open, and to make it easier to switch between them, I like to name them. Todays solution is rather tedious - a batch file that calls a python script that isolates the directory name and stores it in temp file the batch file reads and use as argument in the title command. It works fine, but I dislike the combination and the entire concept of having to create a temporary file for such a small task. The batch language is probably the most terrible scripting environment ever created ;-) -- http://mail.python.org/mailman/listinfo/python-list
Re: Setting win32 console title from Python
Cool. Let me know if you want a copy of p.py (in all of it's hard-coded glory). I can easily put it under Public Domain and you can copy whatever you want out of it. ... jay -- http://mail.python.org/mailman/listinfo/python-list

As I showed in my other post you can parse program output without using a
temporary file.
If all you want to do is to run a script which sets the title when CMD.exe
starts, that is actually quite easy:
c:\temp\startcmd.py
import os
print Python startup
os.execv('c:\\windows\\system32\\cmd.exe',
[/D, /C, title, CMD - + os.getcwd()]
-
Then run regedit and find the key
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun
edit it and insert the name of your script (in this example
c:\temp\startcmd.py).
Now whenever you start a new command processor the script will set the
title and CMD will NOT reset it. It seems that if you set the title from a
subprocess when CMD is starting it will accept your change.
Warning: don't use os.system from the startcmd.py script as that would run
CMD.exe without the /D flag which would run the script recursively as it
starts.

Re: Setting win32 console title from Python
Hi Duncan, sorry, I was unprecise. I'm thinking of a script, called t.py that can be used in the console like an ordinary command. Som if I change directory from S:\scripts to d:\projects and execute the script the title changes to projects etc. I have that functionality today with a combination of a python script and a batch file. I just wondered if I could use python all the way. Apparently I cannot.

I.e., from some old API docs: The SetConsoleTitle function sets the title bar string for the current console window. BOOL SetConsoleTitle( LPTSTR lpszTitle // address of new title ); Parameters lpszTitle Points to a null-terminated string that contains the string to appear in the title bar of the console window. Return Value If the function succeeds, the return value is TRUE. If the function fails, the return value is FALSE. To get extended error information, call GetLastError. See Also GetConsoleTitle Alternatively, you could compile your own extension for title setting/getting called consoletitle.dll using the above API (assuming it works) and its companion GetConsoleTitle.
