[wingide-users] Wing 2.0 plugin question

[Adam Feuer]

Wingware folks,
  Hi, I'm developing a Wing plugin for bicycle repairman. My platform
is Mac OSX.
  
  I built a small plugin using the example.py script, and can access
it from the keyboard.

  I am trying to get the current editor cursor or selection position.
When I access wingapi.gApplication.GetActiveEditor(), I get an
exception NameError: global name singletons is not defined.

  This appears to occur because of an error in the wingapi.py code-
the GetActiveEditor() function should be using self.fSingletons
instead of the global singletons.
  I couldn't test this fix, since I am not set up to build Wing.
  
  I have a couple of questions. How can I work around this problem? Is
there another way to get the cursor position and selection in the
current file...?



Here's my test plugin script:

......

import os
import sys
from wingutils import datatype
from guiutils import formbuilder
from guiutils import dialogs
from scripting import wingapi
from guimgr import messages

import gettext
_ = gettext.translation('scripts_example', fallback = 1).gettext
_i18n_module = 'scripts_example'

_AI = wingapi.CArgInfo


def brm_rename( newname ):
   cursorPos = None
   selectionEndPos = None
   message = ""
   try:
      wingApplication = wingapi.gApplication
      activeEditor = wingApplication.GetActiveEditor()
      if activeEditor is not None:
         scintilla = activeEditor._fScint
         cursorPos, selectionEndPos = scintilla.get_selection()
   except:      
      type, value = sys.exc_info()[:2]
      message = "%s %s" % ( type, value ) 
   buttons = ( dialogs.CButtonSpec( _( 'OK' ), None ), )
   dlg = messages.CMessageDialog( wingapi.gApplication.fSingletons, _(
"brm-rename" ), 
                               _( "New name: %s [%s, %s] (%s)" ) % (
newname, cursorPos, selectionEndPos, message ), [], buttons )

brm_rename.arginfo = {}
brm_rename.arginfo[ 'newname' ] = _AI( _( "New name" ),
datatype.CType( '' ), formbuilder.CSmallTextGui() )
brm_rename.label = _( "brm-rename" )
brm_rename.contexts = [wingapi.kContextScriptsMenu,]

......


  Here's a diff of my attempted fix for wingapi.py:


$ diff wingapi.py wingapi.py.orig 
181c181
<     return CAPIEditor(self.fSingletons, editor)
---
>     return CAPIEditor(singletons, editor)
189c189
<     return CAPIDocument(self.fSingletons, editor.fCache)
---
>     return CAPIDocument(singletons, editor.fCache)


cheers
