How to add a file to a notebook via command line

wxPython Users

Can somebody point me to information to build a programm that behaves
like most text editors.

python nameOfProgram.py sampleFile.txt
=> Program start with sampleFile opend OR
     if programm is already running opens the sample File in a new
Tab.

I don't know what to google for, I get mostly entries for optparse,
but not to this specific topic.

Best,
Marco

Hi,

Can somebody point me to information to build a programm that behaves
like most text editors.

if programm is already running opens the sample File in a new
Tab.

The wxPython Demo includes "Editra" that might give you some pointers.
The Demo is available here:
Redirecting... (scroll down)

On my Pyhton 2.5 installation the following works:

"C:\Python25\Lib\site-packages\wx-2.8-msw-unicode\wx\tools\Editra>python
Editra NEWS"

That pops up an Editra window with the NEWS file opened for editing.

More information about Editra is at http://editra.org

I don't know what to google for, I get mostly entries for optparse,
but not to this specific topic.

Best,
Marco

HTH a little.

Cheers,
Scott.

That's not exactly a wxPython specific question. You may have tried
on comp.lang.python.

I wrote an app that behaves like that under Windows.
The program checks via DDE whether another instance is running already.
If that's the case, the filename is sent to the other instance and the
program terminates.

You can have a look at PythonWin how to implement this.
It's in two files:

...\Lib\site-packages\pythonwin\pywin\framework\intpyapp.py
  Methods:
   MakeExistingDDEConnection
   InitDDE
   InitInstance
   OnDDECommand

...\Lib\site-packages\pythonwin\pywin\framework\intpydde.py

The program checks via DDE whether another instance is running already.

or use wx.SingleInstanceChecker for a platfrom-nuetral option.

The trick then is how to find the running app, and how to send it a message.

It would be nice to have this built-in to wxPython, but alas, it's not, and there are many ways to do it. Try googling SingleInstanceChecker for discussion of some of the options.

I found out that this is more complicated than I exspected. So I put
this feature a bit behind.
I too think Editra is a good example, src/ed_ipc.py is the central
file that manages the messaging. I will investigate this later.

Thanks to all.

That's part of the DDE solution.

Hi,

I found out that this is more complicated than I exspected. So I put
this feature a bit behind.

If your not expecting any other arguments simplest case is just to use sys.argv

i.e)

if __name__ == '__main__':
     import sys
     app = wx.App(False)
     file_name = sys.argv[1]
     frame = MyFrame()
     frame.doOpen(file_name)
     frame.Show()
     app.MainLoop()

Not so complicated right?

I too think Editra is a good example, src/ed_ipc.py is the central
file that manages the messaging. I will investigate this later.

That is only used for IPC (inner process communication) when a second instance starts up it can send any command line args or other commands over to the currently running instance before exiting.
