Re: [Pydev-code] PyDev & Plone

[Fabio Z. <fa...@gm...>]

Hi Timothy,

Well, I haven't gotten zope myself, so, I think I should get it to see how
it works, but I don't know when I'll be able to get it so that I can help
you further... I've passed another message (regarding turbogears) in the
forum, where I give some tips on how to check the debugger... (
https://sourceforge.net/forum/message.php?msg_id=3761753) so, if you have
time and can check it yourself, it would be great (I can give you tips on
things you want to know about), or you can wait for me, but I don't know
when I'll be able to get zope to try it myself...

Cheers,

Fabio

[Pydev-code] Finding imported code

[Timothy R. <tr...@si...>]

	For PyDev - PYTHONPATH I have my project (root folder) in the  
Project Source Folder, and in the External Source Folders I have / 
zope/Products.  For those unfamiliar, with Zope, products that can be  
installed are in this folder. So one of the folders under Products is  
Archetypes. My class extends one of the classes in Archetypes.

class MyClass(OrderedBaseFolder):

PyDev can not find OrderedBaseFolder.  I have tried to add /zope/ 
Products/Archetypes to the ESF's but to no avail.

	Any ideas?  Thanks!

[Pydev-code] PyDev & Plone

[Timothy R. <tr...@si...>]

	O.K., I believe I have everything configured properly.  I have my  
Eclipse workspace added to my zope.conf file as a Products entry, and  
this works, as I could then install into Plone.  I can run, and  
interact with the code.  When an error or warning happens, I can  
click that line and the file opens.  All well and good.  But I can't  
seem to debug.

	I have created a Zope Run instance (as per the Plone site).  I run  
this in debug mode.  I set a breakpoint (or several).  When that code  
gets executed, no breakpoint is hit.

	After starting is debug mode, is there anything that needs to be  
done to connect to the python engine?  Is just setting a breakpoint  
sufficient?  Has anyone else debugged Zope or Plone products under  
PyDev?

	Thanks.

Re: [Pydev-code] Getting bookmarks to display without closing/re-opening file

[Fabio Z. <fa...@gm...>]

You should try to create the markers with the Pydev marker utils:

from org.python.pydev.builder import PydevMarkerUtils

with the method:

createMarker(IResource resource, IDocument doc, String message, int
lineNumber, String markerType, int severity, boolean userEditable, boolean
istransient, List<IMarker> existingMarkers)

You can see an example that uses it at
http://pydev.cvs.sourceforge.net/pydev/org.python.pydev/src/org/python/pyde=
v/builder/todo/PyTodoVisitor.java?view=3Dmarkup

If that does fail, you can try doing a refreshLocal (but I don't really
think it should be needed):

from org.eclipse.core.resources import IResource
from org.eclipse.core.runtime import NullProgressMonitor
resource.refreshLocal(IResource.DEPTH_ZERO, NullProgressMonitor())

Cheers,

Fabio

[Pydev-code] Getting bookmarks to display without closing/re-opening file

[Don T. <nos...@gm...>]

Hi Fabio:

I am trying to write an extension to bookmark all occurrences of a 
selection but I am having trouble getting the bookmark icons to show up 
unless the file is closed and re-opened again.

I have the following code:

     class BookmarkOccurrences(Action):
         def run(self):
             selection = PySelection(editor)
             line = selection.getCursorLine()

             resource = editor.getIFile()
             if not resource:
                 log("Did not get a file resource")
                 return # Give up.

             marker = resource.createMarker(IMarker.BOOKMARK)
             if not marker:
                 log("Did not get a marker")
                 return # Give up

             marker.setAttribute(IMarker.MESSAGE, "This is my marker")
             marker.setAttribute(IMarker.LINE_NUMBER, line)

When this code is executed in a Pydev extension the bookmark shows up 
immediately in the bookmark view, but the little symbol does not show up 
until the file is closed and re-opened.

As far as I can tell the file is synchonized, and I have tried touching 
the file to make sure that it is up to date.

             resource.touch(None)
             if resource.isSynchronized(IResource.DEPTH_INFINITE): 
log("Resource is synchonized")

Any suggestions?

Thanks,

Don.

Hi Don,

Well, I usually look at http://sourceforge.net/docs/a04 (which is pointing
that the cvs will be down for 30 minutes, so, should be shortly up again).

You can get the code from the released source (I'm putting it in sourceforg=

Hi All,

Pydev and Pydev Extensions 1.0.7 have been released

Check http://www.fabioz.com/pydev for details on Pydev Extensions

and http://pydev.sf.net for details on Pydev

Release Highlights in Pydev Extensions:
-----------------------------------------------------------------

- Mark Occurrences is able to highlight all the occurrences of some token i=
n
a file (and is python-aware)

a file (Ctrl+2+R)
- Hierarchy view is final (can now find children classes in referencing
modules)
- Remote debugger
      - Can redirect the output to the client (the signature for starting
the remote debugger became settrace(host=3D'localhost', stdoutToServer =3D
False, stderrToServer =3D False))
      - Maps the locations from the server to the client even if they are
not in the same exact paths
- Force code-analysis in the current editor (Ctrl+2+C)


Release Highlights in Pydev:
----------------------------------------------

- Assign variables to attributes (Ctrl+2+a): Contributed by Joel Hedlund
(this is the first contribution using the new jython scripting engine).
- 3 minor 'quirks' were fixed in the indentation engine
- The debugger had some changes (so, if you had halts with it, please try i=
t
again).
- Allow changing the keybinding for activating the Find next problem
(Ctrl+.)
- The debugger step-return had its behaviour changed.
- Additional scripts location added to pythonpath in the jython scripting
engine
- Transversal of nested references improved
- Fixed problems with compiled modules when they had 'nested' module
structures (e.g.: wx.glcanvas)

That is really good.  Done - I have updated the version on the web page:
http://pilger.googlepages.com/pydevstuff

Actually, this brings up an observation about Pydev extension scripts: 
there is no mechanism to allow a script to have preferences.  I don't 
know how you could provide one, but it would be nice.

I have kept this thing simple as I did not want to get into analyzing 
what the text actually is (code or text) because then I would have to do 
different things. If it is indented multiline text then I should rewrap 
it to the new indentation, if it is a bunch of lines of code starting at 
the same indent then I should leave them alone.

I don't know how to distinguish:

#    This is line one,
#    and this is line two that should be wrapped.

from:

#    print "This is line one, "
#    print " and this is line two that should not be wrapped."

Your observation would also apply to lines inside multiline docstrings.

I bailed on doing this much analysis. I bailed on rewrapping more than 
one paragraph and I even bailed on handling the first line of a docstring.

I may do more later but so far I have not found these restrictions too 
much of a burden, especially when compared to reformatting comments by 
hand.

I think that this thing obeys the Pareto Principle - it does 80% of what 
I want for 20% of the effort required to do it completely.

Hi Don,

I've checked it, and I have some suggestions:
1. Instead of having 80 as the default, you could use the preferences the
user specified as its print margin:

from org.python.pydev.plugin import PydevPlugin
from org.eclipse.ui.texteditor import
AbstractDecoratedTextEditorPreferenceConstants
cols =3D PydevPlugin.getChainedPrefStore().getInt(
AbstractDecoratedTextEditorPreferenceConstants.EDITOR_PRINT_MARGIN_COLUMN);

2. When you try to indent the following:

eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
# class Foo:
#    def m1():
#        pass
#_line_to_wrap2_eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee=
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

if you start doing it at the first line, it will stop there, and not get th=
e
full comment block (so, I think it could indent all that started with '#' +
character, instead of bailing out when it finds the first '#' + space)

Cheers,

Well, the problem is that you need to run it from an UI-thread. The code

if cmd =3D=3D 'onCreateActions':
    from org.eclipse.jface.action import Action
    from org.python.pydev.core.docutils import PySelection

        '''

        def __init__(self, c):
            self.callable =3D c
        def run(self):
            self.callable()

    def runInUi(callable):
        '''

        '''
        Display.getDefault().asyncExec(RunInUi(callable))

    class ExampleCommand3(Action):

                if statusLine is not None:
                    statusLine.setMessage(True, "foo", None)

Hmmm...

When I run your code outside the action listener then it works, but when 
it is inside the action listeners run() then it does not display anything.

Strange, I just tested it here and it worked... it appears in the lower-lef=

it will appear in red).


The script I tested here is:

             print "statusLine %s" % self.statusLine
             if self.statusLine is not None:
                 self.statusLine.setMessage(False, "foo", None)


When I run this I get:

statusLine org.eclipse.ui.texteditor.EditorStatusLine@1133f56

on the console - which I think is good?

But I don't see my message showing up anywhere.

DOn.

[Fabio Z. <fa...@gm...>]

Actually, you probably want to ask the status manager to the editor.
Something as below (untested):

statusLine =3D editor.getAdapter(IEditorStatusLine.class);
if statusLine is not None:
    statusLine.setMessage(False, "foo", None)

[Pydev-code] Writing to the Eclipse status area from a Jython Pydev extension

[Don T. <nos...@gm...>]

Fabio:

I am trying to write a message to the status area on the bottom of the 
Eclipse screen, but I can't get it working.

This is what I have so far:

if cmd == 'onCreateActions':
     ...
     from org.eclipse.jface.action import StatusLineManager

...

             self.statusLine = StatusLineManager()
             self.statusLine.setMessage("hello")
             self.statusLine.update(True)

Maybe I need to call createControl() but I don't know what to supply as 
the 'parent' parameter.

Any pointers will be appreciated.

Don.

In the script: editor.getPythonNature().getPythonPathNature().getCompletePr=
ojectPythonPath()


you can view the interface for editor.getPythonNature().getPythonPathNature=
()
to see what else is available at:

Is there a way to get at the pythonpath for the underlying project?

That's a known bug:

[Pydev-code] Problems with syntax colorizing

[Don T. <nos...@gm...>]

Fabio:

I am having a strange problem with syntax coloring in a Jython file.

My Pydev extension under development allows you to rewrap comments in 
Python/Jython files.  It is mostly working except for one strange case:

I ask it to wrap the first paragraph in the following docstring:

class TextWrapper:
     """
     Object for wrapping/filling text.  The public interface consists of
     the wrap() and fill() methods; the other methods are just there for
     subclasses to override in order to tweak the default behaviour.
     If you want to completely replace the main wrapping algorithm,
     you'll probably have to override _wrap_chunks().

     Several instance attributes control various aspects of wrapping:
       width (default: 70)
         the maximum width of wrapped lines (unless break_long_words
         is false)
   <stuff deleted>
         Break words longer than 'width'.  If false, those words will not
         be broken, and some lines might be longer than 'width'.
     """

     whitespace_trans = string.maketrans(_whitespace, ' ' * 
len(_whitespace))

     unicode_whitespace_trans = {}
     uspace = ord(u' ')

and the text is wrapped fine except that the code that follows is now 
colored as if it were a string too.  However, if I save the file as it 
now is and re-open it then it comes back colored the way it should be 
(and it runs OK).

Also, if I hit ctrl-Z after a paragraph wrap then the text is restored 
to its original state, Eclipse thinks that the file is the same as its 
original state (no * on the tab) but the code is still colored as if it 
were part of the docstring.

This text is part of a largish (>500 line) file and I have not been able 
to reproduce this problem in a small file.  I have put a copy of the 
file on:

PySelection has a 'selectCompleteLine' method that may be what you want...

Eventually I replace this paragraph with a reformatted paragraph. In

Actually, I think you could use the PySelection.deleteLine approach (it
checks the offset of the next line to see what it should delete -- if
there's a 'next' line).

It is possible that this is not true, for example by using a Windows

Maybe, I'm not really sure about this one...

In any case, I can use the IDocument method getLineDelimiter() to get

Yeah, probably could be done...

Oops... Well, yes, Eclipse has one representation for the gui and one for
the internal API.
