Actually, the PyCodeScanner and PyColoredScanner already work well
with the PyPartitionScanner. The FastPythonPartitionScanner was meant
to be a drop-in replacement of the PyPartitionScanner to fix one
issues when string partitions are changed (and I'm not sure what would
it take to finish it without actually going through the process of
implementing it). The code in the PyCodeScanner seems correct for me.

Cheers,

Fabio

Thanks for the reply, and sorry for the top-posting; my web-based client does not work well any other way.


The FastPythonPartitionScanner class looks like interesting code. What would it take to finish it? Just from looking at the code, I notice:


1) No constructor for the class.


2) The PyCodeScanner class (is this unused? i.e. only used with FastPythonPartitionScanner) seems to have a cut and paste error:



   public void updateColors() {
        setupRules();
    }
 
The setupRules() call seems to be from a cut and pasted method.


3) How much would plugin.xml for org.python.pydev have to change to use the new scanner? Is the extension point the same as for the current scanner?


Just curious how close the combination of FastPythonPartitionScanner, PyCodeScanner, and PyColoredScanner are to being completed and useful.


Thanks,


Clark

[Pydev-code] Code to invoke Python interpreter

[<cla...@at...>]

Another newbie question. Where can I read the code that calls a Python interpreter when the user requests that their Python program should be Run? (Including how it connects to a menu item like Run->Run As->Python.)


Thanks in advance.

Re: [Pydev-code] Who instantiates FastPythonPartitionScanner?

 Never mind my followup question. I see that a partitioner and partition scanner get connected to the document.

Thanks. That makes sense, because I even noticed an obvious cut and paste error in the code for FastPythonPartitionScanner.

Now, I cannot see where anyone instantiates PyPartitionScanner or PyPartitioner.  Sorry for the dumb questions; I am new to this!

Thanks for any help.

That class isn't really used. It's an initial attempt to replace the

[Pydev-code] Who instantiates FastPythonPartitionScanner?

[<cla...@at...>]

Searching for FastPythonPartitionScanner only turns up one hit, in FastPythonPartitionScanner.java.  Who instantiates this scanner?

I thought that I had downloaded a ZIP file of all the source code from SourceForge, following a link from pydev.org. However, some code must be missing from that ZIP file. For example, the pydev.core directory tree is not there. I then found another ZIP file that was twice as large and included the core directory and some others, but still no luck in searching on FastPythonPartitionScanner.


Thanks for any info.

[Pydev-code] Jython script for auto-completion

[Jari P. <spa...@ok...>]

Hi!

Is it possible to write Jython script to PyDev that adds stuff to
auto-completion? Such as

    classifiers = [
            "Programming Language :: Python",
            "[CTRL+SPACE]",
        ]

Would yield the list given in PyPi,
http://pypi.python.org/pypi?:action=list_classifiers

I'm also interested is it possible to modify the script that auto
creates the docstrings, it would be handy if it were in
Eclipse\plugins\org.python.pydev.jython_???\jysrc path so it would be
easy to edit... I know it probably is written in Java at the moment so
it is not in Jython source path.

Currently I'm using Sphinx as doc generation and the @-signs are not
used in rST formatted docs, also the used ''' is something that I
don't use, I have """ in docstrings.

These are matter of taste, but it would be easy to "adjust" the taste
if they were Jython scripts... Sometimes doing elaborate configuration
dialogs is harder to get right, editing the code would be easier to
configure.

[Pydev-code] Pydev 1.5.6 Released (Django Integration)

project > pydev > set as django project)
    * Can remove Django project config (right-click project > django >
remove django project config)
    * Custom actions can be passed to the configured manage.py through
ctrl+2+dj django_action -- if no action is passed, will open dialog to

dialog and now works through Ctrl+2+s word_to_find (in the Pydev
editor) and if no word is passed, the editor selection is used

* Go to definiton:

    * Properly works with unsaved files (so, it will work when
searching for a definition on an unsaved file)
    * Properly working with eclipse 3.6 (having FileStoreEditorInput
as the editor input)

* Editor:

    * Automatically closing literals.
    * Removing closing pair on backspace on literal
    * Improved heuristics for automatically closing (, [ and {
    * Removing closing pairs on backspace on (,[ and {

transform the selected import into a string with dots

* General:

    * Code-completion properly working on relative import with an alias.
    * Fixed racing issue that could deadlock pydev (under really hard
to reproduce circumstances)
    * Removing reloading code while debugging until (if) it becomes
more mature in the python side

[Pydev-code] wxPython and PyDev => undefined variables

[Andy D. <an...@do...>]

I am a newbie to the world of Python and its associated technologies. I wanted to get up to speed and selected
PyDev as my vehicle of choice, based on various reviews etc. I also wanted to experiment with developing GUI
code and select wxPython as the preferred framework.

Unfortunately, I am getting issues with PyDev not recognising the various wxPython symbols, despite the fact that I am
importing wxPython. From doing various searches it seems that this is a known bug in PyDev, but can anybody
suggest the preferred solution?

Component versions:

	Python 2.6.1
	wxPython 2.8
	PyDev 1.5.5

[Pydev-code] doc generation from pydev?

[Peter S. <psh...@bl...>]

I'm not a big fan of any current python documentation tools. My concern is that they document the code as it appears in files, not as it is actually used at runtime.

Pydev's introspection is incredible. I was thinking that a little markup and the information that pydev has collected would be vastly superior to any current doc tools.

I haven't dug into Pydev's source at all, but how compatable would it be from this workflow? Is the introspector some library I can run, and then walk over the results? How much work would this be to get into a Python interpreter? Is it tied closely to Jython or the rest of the pydev editor?

I've been thinking about starting something like this for a little while. How feasible would it be?

Can you give details about your setup and create a bug-report for
that? (one for the loss of code-completion and another for the memory
usage)

Please add the following data on the memory report:
1. are those eggs all with .zips or uncompressed?
2. How much memory are you passing to -Xmx ?
3. The problem is on requesting a completion or on a rebuild?

Note that java has the habit of going to the maximum and recycling
memory after that, so, if you pass 1GB to it, it may use all that even
if it could cycle before, as it usually goes for performance rather
than memory -- and it depends a lot on where you're seeing that memory
usage -- personally, I leave it around 500 MB (and I do work with some
large projects). It may be that it has some problem specific to your
setup, but I need more details to get into that).

Also, if you were able to pass a heap dump of your memory in the case
where you see it using too much memory that would help a lot (see the
Getting Started of http://www.eclipse.org/mat/ for details on how to
get that) -- just don't forget to zip it before sending (although it
can still be a big file, so, if you may need to put it in a ftp
somewhere so that I can get it). And also, it would be nice if you can
get a clean eclipse only with pydev to this test (as having svn or
other plugins will probably add too much noise -- in which case I
might not be able to get a proper analysis of the dump).

Fabio

[Pydev-code] Pydev completion

[jmf <jea...@ma...>]

Hi,

Just registred to the mailing list ! I'm using pydev for a long time (about 
three or four years now).

I really like this eclipse plugin.

I have two issues. The first one is related to my current working process & 
tools:

* I'm adding a folder to the pydev python path.
* completion is working well.
* the source folder is deleted and rebuild by my deployment tool (zc.buildout 
+ collective.recipe.omelette)
* completion doesn't work anymore.

To fix this, I need to remove the folder from python path, validate, re add it 
and validate.

I'm under Linux with Aptana Studio, build: 2.0.3.1265134283

The second one is on performance / memory purpose: 

* my current project load 290 eggs in the python path (lots of code)
* When the project is built and completion refreshed, some times I got memory 
related errors. It seems that the more code there is in the python path the 
more pydev need memory to build the project. I'm not sure this issue comes 
from pydev because I have also the svn plugin that is working, but when I 
rebuild from python's path pydev comes to a memory monster : )

I have an intel core2 duo with 4 GO on my workstation but not on my laptop, so 
I need to remove the main features why I'm using pydev on it: completion.

Most of vim users complains about memory usage of eclipse/pydev. But eclipse 
by default only used 50 MO. When activate pydev and ask for completion on a 
simple Plone it comes to 1GO ... a bit too much. Hope you guys will be able to 
improve this in the futur.

[Pydev-code] Prev (command) and Next in debug eval window (Console).

[patrick f. <pa...@we...>]

Hi - I've been wanting this feature for some time and it finally 
occurred to me that I might try writing it myself.

Should ask first.  I'm looking for an emacs-sytle Prev command and Next 
command for the debug-time eval windows (Console).  Where with, say, a 
single keystroke command you cycle through a buffer of saved commands - 
including if the commands are multi-line (you get the command as one 
piece).  Does this exist already?

If not, then how hard would writing it be and what would be involved?

Haven't done any eclipse plugin work yet, but I'm an experienced 
programmer and I believe I saw demos online already that walk you 
through the mechanics of doing a trivial plugin.  I could go through 
that and get some sense of the landscape.

thanx - pat

An idea might be asking the Django guys to make it more friendly to
debuggers so that this can be easier -- maybe even passing a patch to
them -- this is one of the things I have in my checklist after the
django integration is in place.

For the sake of correctness I must say I shouldn't have used
"untraceable" here. There is nothing preventing the thread code to be
traced. It's just that the threading.settrace() hook only works for
threads started using the threading module, but not for the ones
started using the low-level thread module.

Yeah, but some code uses thread.start_new_thread directly, which is

True, but that's the behavior of Django under CPython.

Under Jython it doesn't start a new process, but a new thread. The
thread is started using thread.start_new_thread though, which makes it
untraceable.

Actually, I discovered that the whole thing won't be useful for my use
case (debug the Django dev server under Jython with autoreloading
enabled). Unfortunately the debugger connection will be lost when the
reloading takes place (as it reloads the whole interpreter).

However, here is a use case:

1. You have the following program in PyDev:

import thread

def hello(name):
    print "Hello", name

thread.start_new_thread(hello, ("World",))

2. You put a debugger marker on the print line.

3. You debug the program, but it never stops. Nor on CPython nor Jython.

The fix/hack consisted on the following code (with
self.monkeyPatchThread() being invoked after threading.settrace(), in
PyDB.run()):


    def monkeyPatchThread(self):
        import types
        try:
            import thread
        except:
            import _thread as thread # Python 3
        original_start_new_thread = thread.start_new_thread
        def patched_start_new_thread(func, *args, **kwargs):
            def patched_func(*args, **kwargs):
                import sys
                pydevd_tracing.SetTrace(self.trace_dispatch)
                func(*args, **kwargs)
            original_start_new_thread(patched_func, *args, **kwargs)
        if self.isJythonClassModule(thread):
            thread.start_new_thread = staticmethod(patched_start_new_thread)
        else:
            thread.start_new_thread = patched_start_new_thread

    def isJythonClassModule(self, module):
        try:
            from java.lang import Class
        except:
            return False
        else:
            return isinstance(module, Class)

But it only works correctly with Jython. With CPython it hits the
debugger but then somehow the connection is lost.

I'm probably not pushing this forward (since it won't work for the
Django server use case), but anyway, that's the code if anyone is
interested.

Actually, Pydev should already trigger debugging in any thread (it
sets the threading.settrace to do that).

I believe django creates a separate process to do that, which is the
reason the remote debugger must used for debugging django (a version
without the reload feature should already work for all threads).

What could be done is that the remote debugger is started and each new
process calls pydevd.settrace(suspend=False, traceAllThreads=True),
where traceAllThreads is a flag that is still not implemented, which
calls threading.settrace(debugger.trace_dispatch) for all new threads
-- not only the pydevd_tracing.SetTrace(debugger.trace_dispatch) --
and maybe pass the sys._current_frames to set the tracing for existing
threads.

If you think that'd be useful, I can create that option...

[Pydev-code] PyDev Debugger: Monkeypatch thread.start_new_thread to debug threads?

[Leo S. M. <leo...@gm...>]

Hi all,

When running the Django server under the PyDev debugger there is a
problem: Under Jython the server spawns a worker thread which do all
the actual work while the main thread just keeps monitoring the
filesystem for changes. But, AFAICS, the pydev debugger only monitors
the main thread.

I'm playing with monkey-patching thread.start_new_thread to set
sys.settrace to the internal settrace function used with PyDev when
executing the function in the new thread.

Any obvious reason I'm missing why that may be a bad idea?

[Pydev-code] Turn off graphics-intensive behaviour in eclipse?

[Thomas J. <th...@sk...>]

One of the deployment alternatives of eclipse+pydev we deal with is 
running it remotely via Exceed/Citrix.
This unfortunately causes some performance problems:
When a project is created, there is a pop-up window displaying file 
names as they are read and analysed into the project, at a wild pace. 
Apparently Citrix/Exceed has a very hard time keeping up with the 
graphics updates, causing a disastrous communication degradation with 
the remote location.

There is really no reason except for the enjoyment as far a I can see to 
actually see the rapid burst of names.
Is there a way to turn this off, to make this process 'quieter' 
graphics-wise ?

Thank you in advance

Actually, it's no longer bound to Ctrl+Enter, but Ctrl+Alt+Enter (see:
http://pydev.org/manual_adv_interactive_console.html )

As for sending a Ctrl+C, the problem isn't really on the Eclipse side
of things, but in the design of the interactive console: in Python,
only the main thread will catch signals, so, that's where you send the
Ctrl+C, but in the interactive console it'll only evaluate what you
send on a line by line basis, where the main thread is the actual
interactive console, so, I'm not sure how useful that'd be (or are you
just aiming at killing the process and providing a secondary option?)

The code to look at the Python side is pydevconsole.py (at
org.python.pydev/PySrc).

Hi Kostas,

The java-side class that handles it is AbstractShell.java and in the
Python/Jython side it's pycompletionserver.py
