Python macro access to command output window

Posted by man_who_was_thursday on 2009-08-07 11:38

This seems like it should be simple, but I've searched and can't find the answer. I am running a Python macro that interacts with another proprietary IDE. I can build and capture the error output. Is there a way to send this output to the "Command Output" tab and have it parsed the way you can with a simple "Run" item in the toolbox?

I am new to Python, but I'm using it because it allowed access to the ActiveX control used to script the proprietary IDE.

Regards,
Dave

It is not easy for Python macros to access to the actual UI elements, but here is some code that should get you there:

from xpcom import components
wm = components.classes["@mozilla.org/appshell/window-mediator;1"].getService(components.interfaces.nsIWindowMediator)
win = wm.getMostRecentWindow("Komodo")
# Get the run output element in the UI.
elem = win.document.getElementById('runoutput-scintilla')
elem.QueryInterface(components.interfaces.koIScintillaView)
scimoz = elem.scimoz
scimoz.readOnly = False
scimoz.text = "Hello\nthere\n"
from xpcom import components
wm = components.classes["@mozilla.org/appshell/window-mediator;1"].getService(components.interfaces.nsIWindowMediator)
win = wm.getMostRecentWindow("Komodo")
# Get the run output element in the UI.
elem = win.document.getElementById('runoutput-scintilla')
elem.QueryInterface(components.interfaces.koIScintillaView)
scimoz = elem.scimoz
scimoz.readOnly = False
scimoz.text = "Hello\nthere\n"

Cheers,

Todd,

Thanks for the code. I had to change it slightly to make it run without errors. I added an import line, and changed the case. Unfortunately, the text is not being displayed.

Here's the code:

from xpcom import components
wm = components.classes["@mozilla.org/appshell/window-mediator;1"].getService(components.interfaces.nsIWindowMediator)
win = wm.getMostRecentWindow("Komodo")
# Get the run output element in the UI.
elem = win.document.getElementById('runoutput-scintilla')
elem.QueryInterface(components.interfaces.koIScintillaView)
scimoz = elem.scimoz
scimoz.text="Hello\nthere\n"
from xpcom import components 
wm = components.classes["@mozilla.org/appshell/window-mediator;1"].getService(components.interfaces.nsIWindowMediator)
win = wm.getMostRecentWindow("Komodo")
# Get the run output element in the UI.
elem = win.document.getElementById('runoutput-scintilla')
elem.QueryInterface(components.interfaces.koIScintillaView)
scimoz = elem.scimoz
scimoz.text="Hello\nthere\n"

Komodo Version: 5.1.4, build 3797
WinXP Pro

Any more info (Bump)

I still can't get this to work. Any other ideas?

The above code should work - note you'll need the "from xpcom import components" line as noted by Dave.

If it's not working for you, you might want to install the Komodo Developer Extension:
http://community.activestate.com/xpi/komodo-developer-extension

then use the "Tools->Extension Developer->PyShell" to launch an interactive Python window, paste in line by line and see where it's failing...

Cheers,
Todd

Slight improvement

Actually Todd's code works. I made it append to existing text instead of overwriting it:

from xpcom import components

def log(line):
    wm = components.classes["@mozilla.org/appshell/window-mediator;1"].getService(components.interfaces.nsIWindowMediator)
    win = wm.getMostRecentWindow("Komodo")
    # Get the run output element in the UI.
    elem = win.document.getElementById('runoutput-scintilla')
    elem.QueryInterface(components.interfaces.koIScintillaView)
    scimoz = elem.scimoz
    scimoz.text += line + '\n'

log('hello there?')

from xpcom import components

def log(line):
    wm = components.classes["@mozilla.org/appshell/window-mediator;1"].getService(components.interfaces.nsIWindowMediator)
    win = wm.getMostRecentWindow("Komodo")
    # Get the run output element in the UI.
    elem = win.document.getElementById('runoutput-scintilla')
    elem.QueryInterface(components.interfaces.koIScintillaView)
    scimoz = elem.scimoz
    scimoz.text += line + '\n'

log('hello there?')

Error when running in pyshell
man_who_was_thursday | Wed, 2009-09-23 06:18

I loaded the developer extension and ran the macro line by line in pyshell. When I type the line:

elem.QueryInterface(components.interfaces.koIScintillaView)

I get the following error message:

XPCOM component '' (implementing koIScintillaView, nsIDOM3Node, nsIDOMElement, nsIDOMElementCSSInlineStyle, nsIDOMEventTarget, nsIDOMNSElement, nsIDOMXULElement)

I can continue and append text to the scimoz text property. If I do a "print(scimoz.text)" the text is echoed to the python console, but the text does not appear in the Command tab.

Any ideas?

re: adding the text to scimoz

SciMoz may be in a read-only state, so try adding this before the set text call:

scimoz.readOnly = False
scimoz.readOnly = False

It works

That did the trick! Thanks. I had tried this awhile back, but I think there was another error and I took the line out.
