I did spot the size bump & wondered if that was a factor.

Makes sense - I've been a happy PyDev user for a couple of years
without touching Jython, but am seeing the Scripting as being a
majorly useful feature.
Being able to plug-in any Jython version would be ideal...how hard
would it be to separate out the bridging code to enable pointing to
any Jython install?

Many thanks,
Fran.

Re: [Pydev-code] Jython Scripting - is this limited to v2.2?

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

Hi Fran,

Unfortunately yes, right now it's limited to Jython 2.2 (which is the
internal version used). There are currently no plans to upgrade that
version (mostly because it'd raise the size of PyDev a lot -- the jython
jar is currently 1.5 MB, and the update would make it around 8 MB... The
whole PyDev with Jython is right now 7 MB, so, it'd double the size just
for that update).

I'd consider adding it only if it makes the startup of the PyDev editor
much faster (right now, the first time you open a PyDev editor, it has a
delay: that's Jython loading... I'm almost considering removing it because
of that delay -- or at least making it optional, in which case it might be
worth putting it in a separate plugin -- then, maybe it'd be worth updating
the version, as users that don't want it don't need to get it).

Cheers,

Fabio

[Pydev-code] Jython Scripting - is this limited to v2.2?

[Fran B. <fra...@gm...>]

I have been playing with the Jython scripting interface which I just
discovered & have been very excited about, however I find that it
seems to be limited to v2.2, is that true?
I have 2.7b1 installed & can launch an interactive console with that

Many thanks for any help,

[Pydev-code] PyDev 2.7.2 Released / Help to keep PyDev alive

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

Hi All,

PyDev 2.7.2 has been released and needs help to be kept being developed.


Release Highlights
----------------------------

* Updated icons in PyDev to match better a dark theme.
* Improved minimap.
* Fixed issue copying qualified name when editor is not in the PYTHONPATH.
* Removed call home ping from PyDev.
* Fixed issue on Ctrl+1 assist to ignore some warning.
* Improved comment/uncomment to deal properly with pep8 formatting.


Helping PyDev
---------------------------

Currently, PyDev is raising funds so that it's development can be continued
and a lightweight toolchain for editors inside Eclipse can complement it.

Please help keeping PyDev alive! More details can be seen at:
http://igg.me/at/liclipse


What is PyDev?
---------------------------

PyDev is a plugin that enables users to use Eclipse for Python, Jython and
IronPython development -- making Eclipse a first class Python IDE -- It
comes with many goodies such as code completion, syntax highlighting,
syntax analysis, refactor, debug and many others.

[Pydev-code] python interpreter from within eclipse

[Jon J. <jos...@gm...>]

I see some references to starting an interactive interpreter but I have been unable to do so. Is this possible and  if so how do I go about it?  Thanks, Jon.

[Pydev-code] Refactoring pydevd_file_utils.py

[Malte F. <mal...@be...>]

Hi,

I order to do some remote debugging, I recently copied pysrc to the
server and modified pydevd_file_utils.py as described in
http://pydev.org/manual_adv_remote_debugger.html. As far as I
understand, there is no separation between the (potentially) system-wide
module pysrc and its user-specific or project-specific configuration.

I would like to suggest refactoring the configuration variables out of
pydevd_file_utils.py into a new file pydevd_config.py. That way, it
should be possible to package pysrc and install it as a system-wide
module on a remote debugging server. Each user or project could specify
an appropriate configuration in a copy of pydevd_config.py. Of course,
that copy must be placed where it is found and imported before the
generic version in the system-wide package is found.

I'm attaching my versions of pydevd_file_utils.py and pydevd_config.py,
based on pydev 2.7.1, which I created for testing this approach.

[Pydev-code] Run Configurations - Auto Reload

[Sayth R. <fle...@gm...>]

Is it possible to create run configurations with autoreload. Was reading
here http://pydev.org/manual_adv_django.html

For Run Django with autoreload it notes this.

import pydevd
pydevd.patch_django_autoreload(
patch_remote_debugger=False, #Note that the remote debugger patch
setting should be False on a regular run
patch_show_console=True
)

just *before* the *if _name_ == "_main_":* in your manage.py module
Is it possible though instead of adding this to each project to set up a
run configuration that will run with autoreload each time I open a new
Django project?

[Pydev-code] Using PyDev witihin an Eclipse Plugin

[Mason W. <mas...@gm...>]

Hello,

I've been struggling for over a month now to try to get Eclipse to
recognize Jython classes within Java when my plugin is activated. I've
posted several times to Stack Overflow with the PyDev tag but haven't
gotten much in the way of responses so I thought I'd give this a try.

Even if you don't have an answer for me, I'd appreciate a quick reply so I
know this email hasn't simply gone to the bit bucket.

I'm using the JythonObjectFactory described in
http://www.jython.org/jythonbook/en/1.0/JythonAndJavaIntegration.html#using-jython-within-java-applications
.

When I run a JUnit test in an Eclipse plugin (not a JUnit-Plugin test and
so I'm not activating the plugin), the factory works just fine. When I call
validateFactory.createObject(), I can cast it to the Java Interface I wrote
and everyone is happy.

When I try to do the same thing when I activate the plugin (via a product
run configuration), I get the error:
java.lang.ClassCastException: org.python.core.PySingleton cannot be cast to
com.myorg.MyInterface.

When I run the unit test, if I call
System.out.println(validateFactory.createObject().getClass().getName());
the output is
org.python.proxies.MyInterfaceDefinition$MyInterfaceDefinition$3
MyInterfaceDefinition is a Jython module that defines a class
MyInterfaceDefinition that inherits from com.myorg.MyInterface
but when I do the same call from my plugin, the output is:
org.python.core.PySingleton

Does this ring any bells for anyone?

Thanks for taking a look at this.

Mason Wardle


P.S. Here's a little background info:

I'm running in Eclipse 3.8.1 on Linux using PyDev 2.5.7.

Note that in order to get this far with the plugin, I had to create a
Jython plugin from the jython-2.5.3 jar and make it a dependency in my
plugin. I also had to manually set JYTHONPATH in environment variables in
the run configuration and append to sys.path in my Jython module, both are
things that seem to be automatically done by the PyDev plugin when running
my JUnit test.

[Pydev-code] Customize list of known global functions

[Andreas P. <an...@fr...>]

Hi,

I'm wondering wether its possible to somehow teach PyDev about global 
functions that are automatically available in the interpreter?

I have an application which adds a few modules via the C API to a 
Python interpreter and imports all symbols from one of these modules 
into the global namespace. I can provide a predefinition file for all 
the modules and that works fine, but I haven't found a way to tell PyDev 
that there are additional functions in the global namespace.

Is there a way to do this? I'm including PyDev in an Eclipse app, so 
having a way to do this via API would be fine for me.

Andreas

PS: That application using the python interpreter can unfortunately not 
be used as interpreter in PyDev since it does not allow running 
arbitrary python scripts at the moment.

Re: [Pydev-code] code folding

[Paul <pau...@af...>]

Hi All,

Sorry for long time no reply, has been a busy week. I appear to be
mostly set, I'm managing to make changes and test them, so everything
seems to be configured correctly.

> This link explains this process:

> https://help.github.com/articles/fork-a-repo
Thanks Andornaut, I must still look at this. In the mean time I'm
progressing on my own branch, so it hopefully won't be too difficult to
merge the changes back in or post a patch.

Luckily this is not the case. Or rather, AFAIU, the only project I am
changing is org.python.pydev, so only that one needs to be built each
time (and, apart from my changes, it does build), it's the other
projects that have missing deps, but as I'm not changing them, I don't
need to build them. So far everything seems to work, I can make
changes, run as "Eclipse Application", and see a new Eclipse with my
changes, so I can test.

I must still have a look at the test suite and see how to add one. I'm
leaving that for last :) mostly because I'm not familiar enough with
anything to have clear ideas of how I intend to implement it.

I'm happy to report some success so far. I've got code folding working
for some hard coded tags, and have finally managed to get somewhere on
figuring out the whole preferences page stuff. I'm still busy
putting custom tag preferences together, then I need to expand the
folding code to allow multiple tags instead of just one, then it's on
to the test cases.

I have found some other stuff that looks weird, but I don't think it's
due to what I'm doing, but I still need to verify that it exists in the
current code folding.

A few hurdles, and much learning still to do. Probably going to take
more time than it should, but at least I feel I have a solid start.

Many thanks for the help so far

Re: [Pydev-code] Flask & jinja2

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

Hi Sayth, as Jinja2 seems very close to Django, it may be worth using
the Django templates editor (it's distributed along with Aptana Studio
3 -- you just have to change the file association to open html files
with that editor in the file association).

Aside from that, from what I understood, Flask itself would already work right?

Cheers,

Fabio

[Pydev-code] Flask & jinja2

[Sayth R. <fle...@gm...>]

Hi

Was hoping that PyDev could support Flask. In respect to flask itself
it is python and templates structured under 2 folders so it is
relatively easy to add the basic structure.

Flask however uses Jinja2 templates http://jinja.pocoo.org/docs/ for
its html. This is where I am requesting more help as the templates
don't format well in eclipse.

Is this at all likely?

I assume that it's referring to the Java version, not eclipse. So,
Java 1.5 (5.0)

Before you can "run" your changes, you will need to "build" (compile)
the code. Therefore, you will need to meet all of the "build"
dependencies.

Hi Fabio,

Thanks for the reply. I've got started already, but there are some
things that I'm not clear on. See comments inline.

Ah, so? Pity, scripting would have been easier, I think, but I will
experiment with the plug-in code. Probably a better solution in the
long run.

Ok, I have java version 1.6.0_21, which is java 6 AFAIU. I also have
Eclipse Juno, version 4.2.0. The instructions at the given link have a
few things I don't understand.

Firstly, they talk about changing the compliance level from 1.4 to 5.0.
I don't have a 5.0 in Eclipse, only 1.3 through 1.7, and it's currently
on 1.6, so I can only assume this is correct. The numbering must have
changed, and I assume 1.6 is java 6 and the 5.0 was java 5, so this
should be fine.

Secondly, they talk about forking the code at github, then creating
your own branch. I'm not really familiar with git, or github, so I'm
not sure if I should be doing the fork on github or what, but for now
I've "git-clone"d the github code to my machine and made a feature
branch (with git checkout -b), so if I work on that local copy I should
be able to submit a patch later, right? There's stuff in the guide about
creating a pull request on github, but I don't have a public IP, so I
think I'll need to mail patches.

Then the developers guide talks of having a dependancy on Aptana, but
only if building the code, not if just running the changes in Eclipse.
As I understand it, I will just be making changes, and then running it
in a new Eclipse from inside Eclipse, so I won't need Aptana?

It also talks of making changes to
org.python.pydev.core/tests/org.python.pydev.core/TestDependent.OS.properties,
which I assume would be
org.python.pydev.core/tests/org.python.pydev.core/TestDependent.windows.properties
for me. I see a lot of stuff in there, including things like
IronPython. Do I need all of that installed? There are things there I
don't even know, like PIL. And the google app engine? Surely I don't
need all of that to make the simple changes I am contemplating? Is
that stuff only needed for running the tests?

Lastly, the guide talks about reading the instructions
at /plugins/org.python.pydev.build/build_cmd.txt, but that seems to do
a lot of git stuff and I'm not sure quite what that relates to. I'm
hoping I don't need that stuff just to test and submit a patch.

What am I trying to run? I tried to right-click on the org.python.pydev
project (in the package explorer), and under the "Run As" submenu of
the context menu was "Eclipse Application", but this complains about
errors in com.aptana.interactive_console,
org.python.pydev.django_templates and org.python.pydev.mylyn. I have
tried clicking "Proceed", and sure enough a new Eclipse opens with my
changes, so I'm assuming that despite the errors I'm on the right track
and can safely ignore the errors to proceed.

Sorry if I sound terribly noobish, but I've not had much exposure to
either java or Eclipse before (and only fairly recently to python). I
think I've got things chugging along enough to make the changes I need,
and hopefully submit a patch at the end.

Again, many thanks for the help.

Re: [Pydev-code] code folding

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

Hi Paul,

For this situation I think doing it in the code directly (and not in
scripting) would be a better choice, as you'll be able to edit the
preferences and the current code isn't really meant to be extended for
what you want in scripting.

The first thing would be the code there compiling properly. Make sure
you have downloaded the java SDK (preferably Java 5, but could be a
later version too) and the latest Eclipse 3.8 SDK and try following
the instructions from: http://www.pydev.org/developers.html

After that, the related classes would be:

org.python.pydev.editor.codefolding.CodeFoldingSetter: It'd be mainly
configuring org.python.pydev.editor.codefolding.CodeFoldingSetter.getMarks(IDocument,
SimpleNode) to return more folding entries.

org.python.pydev.editor.codefolding.CodeFoldingSetterTest: Please do a
test-case for your situation so that it keeps working after the
initial implementation is done :)

org.python.pydev.editor.codefolding.PyDevCodeFoldingPrefPage: add the
related preferences for the option you want to add.

Note that you may run an Eclipse with your own code changes doing a
run configuration:

menu: run > run configurations > eclipse application (right-click for
new eclipse application) > run.

Cheers,

Fabio

[Pydev-code] code folding

[Paul <pau...@af...>]

Hi List,

I see from this
(http://sourceforge.net/tracker/index.php?func=detail&aid=1841410&group_id=85796&atid=577332),
that PyDev still doesn't support code folding on custom tags. Not sure
if this is the latest word on it or if I'm missing something, but from
my searching on the net and the mailing list archives, I can find
nothing more on it, and it seems at least a few people would like to
see this feature.

I've had a stab at it myself, trying both hacking the PyDev plug-in,
and scripting it with the jython scripting support, but so far no luck.
I'm afraid I'm new to Eclipse plug-in dev, and am having some troubles.

I was wondering if there was any further info on this, anybody already
involved in PyDev work that would add this (as it seems like it would
be fairly quick to add for someone who knew the internals of PyDev), or
if not, anybody who could help me get pointed in the right direction?

For hacking the plug-in, I grabbed the code off github, unzipped the
zip (I didn't want to clone the repo yet, as I just wanted to poke
around quickly for now, and don't already have git installed), loaded it
into Eclipse, but can't seem to run it. Something about the build path
being incomplete and not being able to find java.lang.Object. I'm sure
this is really simple, but I'm not very experienced with Java or Eclipse
dev, so I'm just not quite sure how to set it up correctly.

For the scripting approach, I've gotten further. I have hooked up an
IDocumentLister in the 'onSetDocument' event to listen for changes to
the document, but from looking at the plug-in code, it looks like I may
actually want an IModelListener hooked up instead. I can't seem to get
that part working, tho. Once I have the correct listener, I'm thinking
I can check the document to get access to the comments, look for a
custom comment, and add the mark to the listener (simple, right?).

Either approach should do, and both seem to have their advantages,
although the scripting approach may be easier for me to get working. Any
comments as to which is preferable?

Anybody able and willing to help me out?

Thanks all

Paul

[Pydev-code] PyDev 2.7.0 Released

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

Hi All,

PyDev 2.7.0 has been released

Details on PyDev: http://pydev.org
Details on its development: http://pydev.blogspot.com

Release Highlights:
-------------------------------

* **Code formatter**:

 * Number of spaces before a comment can be configured (default: 2
spaces as pep-8 recommends)
 * Minimum number of spaces before start of comment may be configured
(default: 1 space as pep-8 recommends)
 * Right trim lines now also properly trims comments.
 * When the auto-formatter is enabled, if syntax errors are present
the code-formatting is not applied (it could end up getting things
wrong in this situation).

* Python 3.3 'yield from' syntax now properly supported.

* Fixed issue when unable to get filesystem encoding when configuring
interpreter.
* Debugger: 'Enable Condition' checkbox in break properties dialog no
longer ignored.
* Fixed ClassCastException during parse in Python file with yield in
global scope.
* Fixed StackOverflowError in fast parser (i.e.: parser used to get
only the outline of the code).
* PyDev Mylyn integration can now be installed on Eclipse 4.2.
* Fixed NPE when trying to add interpreter and it detected directory
which we could not list() in Java.
* Fixed cache issue in code-completion (nature.startRequests() could
end up not having nature.endRequests() called).
* Save a bit faster on big files (i.e.: No longer doing
invalidateTextPresentation on each save).


What is PyDev?
---------------------------

PyDev is a plugin that enables users to use Eclipse for Python, Jython
and IronPython development -- making Eclipse a first class Python IDE
-- It comes with many goodies such as code completion, syntax
highlighting, syntax analysis, refactor, debug and many others.

Re: [Pydev-code] eclipse isnt accepting anything

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

It seems this is related to using python 3 (where print is no longer a
statement and must be called as print('something')).

Note: this forum is not the appropriate location for these
questions... please ask at stackoverflow (and you may add a 'pydev'
tag if you think it's related to pydev).

[Pydev-code] eclipse isnt accepting anything

[julius <com...@ya...>]

hi,

i tried some testcode on windows 7 in eclipse with pydev and it worked, but somehow now i cant even use a simple print statement.
the error is: SyntaxError: invalid syntax


example:

print "lala"



console:

  File "C:\Users\julius\workspace\tcpdump\testing\test.py", line 1
    print "lala"
               ^
SyntaxError: invalid syntax




the code is in a python module, but eclipse refuses to even run one line.
however, import statements are recognized somehow.
what could this be?

[Pydev-code] enable "Mark Occurrences" whenever cursor position changes

[Minjae D. K. <min...@gm...>]

Hello,

PyDev has a 'Mark Occurrences' that I find useful.  However, I realized
that it does not work when I use vi keystrokes (h,j,k,l) to move the cursor
(I am using a vi-emulator plugin, and there are several vi and emacs
plugins out there).  The mark occurrences feature works only when I use
arrow keys or the mouse to move the cursor, and this strange behavior has
been noted before me as well.  I wondered why, so I took a look into the
code and found the logic in PyEdit.java:

       public void keyReleased(KeyEvent e) {
            if (e.character == '\0') {

                switch (e.keyCode) {
                    case SWT.ARROW_DOWN:
                    case SWT.ARROW_UP:
                    case SWT.ARROW_LEFT:
                    case SWT.ARROW_RIGHT:
                    case SWT.HOME:
                    case SWT.END:
                    case SWT.PAGE_UP:
                    case SWT.PAGE_DOWN:
                        int offset = getOffset();
                        if (offset != lastOffset) {
                            notifyCursorPositionChanged();
                            lastOffset = offset;
                        }
                    default:
                        return;
                }
            }
        }

In the code, to the best of my knowledge, {notifyCursorPositionChanged} is
the part that eventually triggers mark occurrences.  As the above logic
filters for arrow keys and several others, obviously vi movement keys never
make to the {notifyCursorPositionChanged}.

Now, this is not strictly a bug as PyDev works fine.  However, it makes me
wonder why there is that keycode switch logic in the first place.  The {if
(offset != lastOffset) } conditional already and correctly tests whether
the cursor position has changed.  And this condition alone should be enough
to trigger notifyCursorPositionChanged().  I simply do not understand the
reason behind switch logic filter.

So, my question is, could we get rid of the switch logic completely and use
the if conditional alone?  This would coincidentally solve my problem :)
Please feel free to provide opinions -- this is my first time looking at
the pydev source code, and I will be happy to be enlightened.

Best Regards,
Minjae

[Pydev-code] Changing how the code is rendered on the screen

[Martin C. M. <ma...@ma...>]

Hi all,

I'd like to modify how the Python code is rendered on the screen, to 
make it different from how it's stored on disk.  Some random examples:

- Display list comprehensions as [for x in foo: expr(x)]
- Display return statements -- "return expr" -- without the return 
keyword, i.e. just "expr".
- For a pair of statements like this:

local_var = expr
my_func(local_var)

render them as this:

my_func(expr)

I'm pretty familiar with Python and Java, but have never developed 
Eclipse plugins before.  Any suggestions as to what parts of the code I 
should read first?  What docs?

The existing "collapse comments" is an example of this.  Would that be a 
good place to start?

Thanks,
Martin
