[Pydev-users] PyDev 4.4.0 Released

[Fabio Zadrozny]

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

* Improved PyDev Package Explorer to give more information when all
elements are filtered.

* Code completion improvements: when a parameter is typed in the docstring,
assigning it to an instance gives proper code-completion results when
accessing the instance.

* Fixed issues dealing with ansi colors in the interactive console.

* When autopep8 is applied as the code formatting engine, the region
selected is used to specify the lines for formatting.

* Minor improvements in the debugger.


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

PyDev is an open-source Python IDE on top of Eclipse for Python, Jython and
IronPython development.

It comes with goodies such as code completion, syntax highlighting, syntax
analysis, code analysis, refactor, debug, interactive console, etc.

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


What is LiClipse?
---------------------------

LiClipse is a PyDev standalone with goodies such as support for Multiple
cursors, theming, TextMate bundles and a number of other languages such as
Django Templates, Jinja2, Kivy Language, Mako Templates, Html, Javascript,
etc.

It's also a commercial counterpart which helps supporting the development
of PyDev.

hi,


im using eclipse 4.5.1 and pydev from http://pydev.org/updates.
breakpoints are just ignored and the program runs to the end, it works
for a method only containing a print statement...there pydev stops to
show debugging information.

but for another method in the same file, it does not work.
that particular method as a for loop enclosing another, but the debugger
just skipts straight to the end of that method and shows the output
after both loops ran to the end

just above the first loop is a breakpoint.

adding:
import pydevd
pydevd.settrace()

source:http://stackoverflow.com/questions/9486871/pydev-breakpoints-not-working

to the code says it cant find "pydevd" but the code stops a line below
settrace and i can run the for loops step by step.


any ideas?

​Well, doing pydevd.settrace() adds a programatic breakpoint, so, it should
always work... as for why it doesn't work, on some situations Python itself
kills the debugging (for instance, if you have a StackOverflowError
anywhere, even if treated, it'll break the debugger), and I know it can
have some issues on some frameworks... Can you give more details on your
code? Do you have some code you can share where I can reproduce the issue?

Best Regards,

set a breakpoint inside the method something, on my pc that thing prints
100 numbers and then quits instead of waiting for me




class perfect_class(object):


def __init__(self):
pass



def something(self):

for i in range(10):

for j in range(10):

print i



if __name__ == '__main__':
x = perfect_class()
x.something()

​Humm, tested it here and it works for me...

Please create a bug report for that at
https://sw-brainwy.rhcloud.com/tracker/PyDev/ and let's continue the talk
about this there...

In the report, please specify your os and python version.

Cheers,

hi,


when creating a new project, selecting jython and using the default auto
config i get:

See error log for details.

entering jython in window -> preferences shows the the jython
interpreter page,
according to:
dpkg -L jython| grep jar
/usr/share/java/jython-2.5.3.jar
/usr/share/java/jython.jar


this is the location of jython, but specifying either with "new..." does
not work...same error as before.
default debian jessie installation.

any ideas?

​Try downloading the jython from jython.org and using that version instead
of the one in the system to check if it works... (jython should have all
dependencies builtin, but it seems the version you're using doesn't have
them).
