install pydev without rights to eclipse installation - python

My apologies if this has already been asked and answered. I don't know enough about eclipse & pydev setup to know what to search for.
I'd like to use pydev, but can't modify the existing installation of eclipse. Do I need to install my own eclipse so that I can then install pydev into it, or is there a way to install pydev off to the side such that I can then use it with the existing eclipse?

The best solution I found was multiple installations: eclipse is not that big (~250mb I think), but it's quite slow, so you'll want to have as little plugins as possible.

Something that worked quite nicely for me when I was using Pydev with Eclipse as a non-privileged user on a shared computer was to install Eclipse+Pydev on a flash drive. You have the added advantage of being able to work from any computer while having your usual settings.

Run Galde Gtk3+ Python under Windows

i've created a student-managing-software for linux which use different packages (tkmessageboxes, glade-builder, gtk3+). Now, there are a lot of people how asked how it can be used under windows but i've no idea. So, does someone know how to use these packages under windows or is it impossible? THX
Well I would say it is up to the developer to make an actual installer for it, but you can get all of the dependencies through the MSYS2 project.

Eclipse - Installed PyDev and nothing changed

This isn't my first time using Eclipse or installing PyDev but this is the first time it both succeeded and failed.
It succeeded because it installed, it shows up as being installed and installation went on fine without a problem.
It failed because nothing has shown up, there is no Python perspective, no PyDev views in the view list, no new projects under PyDev, no PyDev preferences. It is as if it is not actually installed at all.
The only thing I did differently is extract the latest eclipse to a folder called ~/eclipse and create a short cut to run it there (the latest Eclipse), usually I use apt-get to install eclipse, realise it's an old version (C++11 stuff missing) then upgrade and do this. Somehow PyDev is usually carried forward.
I'm not sure how it can list it as being installed but have this error, I'd appreciate any help you guys can offer.
I bet it's the problem of 3.x version of PyDev. It demands java 7.
2 solutions are possible:
Install java 7. re-run the Eclipse, Pydev should function well now. OR
Install last 2.x version of PyDev.
To do it
1) Remove PyDev : In Eclipse About window click Installation Details
button below. You will see controls for removing plug-ins.
2) Install 2.x version of PyDev:
Eclipse Help->Install New Software.
REMOVE CHECKBOX "Show only the latest version" located at the bottom of the dialog.
Choose Pydev update site from the list and in the appeared list of PyDev versions choose latest in 2.x branch.
The problem is really that sometimes even installing java 7, Eclipse does not get it.
In http://pydev.org/download.html, there's a section called: PyDev does not appear after install!
Try to follow it to see if it fixes your problem (i.e.: making Eclipse find java 7).
Another option would be using PyDev standalone (i.e.: LiClipse). Although it's commercial, it should come with all the requisites builtin (so, no hassles to install) and is updated whenever PyDev itself is updated.

Questions about Django development on Mac OS X

I'm new to Mac (as of yesterday), and I have Snow Leopard. I've just easy_install virtualenv, and it doesn't work. I read a couple other SO questions about the same exception I had, and it seems that I need XCode installed. Before I go down a rabbit hole, installing a 3.5Gb Apple-specific code library for something Python related, and who knows what else at this point, I figured I'd stop by here and find out what's typical for Django developers with Macs.
What tools / libraries that are Python/Django specific, but non-project specific do you commonly use?
Is XCode really necessary to use virtualenv (and potentially other things, or is this just one way to solve my issue?
Are there other Mac issues that you've run into with basic Django development?
Do you have any other tips for a veteran Django dev who is an absolute Mac noob?
You will need XCode, yes. You'll need it for any libraries that need compiling, apart from anything else.
Please don't install MacPorts, though, as recommended by titaniumdecoy. It tries to install its own versions of everything, which is unnecessarily confusing, and takes you out of the usual Mac development stack. A much better package installation tool is homebrew, which uses the built-in tools to install software via a series of recipes. It's excellent.
I started use Mac a couple days ago and I have same problem. You need XCode, yes!
Packgers manager, like apt-get, you can try HomeBrew.
To develop in django, I use TextMate, with some bundles to django.
To develop in python I use pip, virtualenv and virtualenvwrapper, this is awesome.
As an iOS developer I can't comment on the specifics of Django development, but the following should help get you started.
Install macports immediately. You can install virtually any unix tool you can think of with a single command, including virtualenv. (Update: Use HomeBrew instead as suggested in other answers: see comments for why.)
You need to install Xcode to get the Mac OS X developer toolchain (gcc, etc.) unless you prefer to install everything yourself.
If you use Eclipse, the Pydev plug-in is one way to go. TextMate is probably the most popular text editor on the mac. The Python Wiki has a comprehensive rundown of your options.

Python Code Completion

After using C# for long time I finally decided to switch to Python.
The question I am facing for the moment has to do about auto-complete.
I guess I am spoiled by C# and especially from resharper and I was expecting something similar to exist for Python.
My editor of choice is emacs and after doing some research I found autocomplete.pl, yasnippet and rope although it is not clear to me if and how they can be installed in a cygwin based system which is what I use since all the related documentation appears to be linux specific...
The version of emacs I currently use is 23.2.1 which bundles the python mode that although useful is far behind from whatever research has to offer.
My question to python users has to do about how common is autocomplete vs manual typing (using M-/ where possible) ?
I am thinking about just memorizing python build-in functions like len, append, extend etc. and revert close to a pre-autocomplete editing mode. How different such an approach is from what other pythonistas are doing?
I found this post
My Emacs Python environment
to be the most useful and comprehensive list of instructions and references on how to setup a decent Python development environment in Emacs regardless of OS platform. It is still a bit of work to setup but at least it covers the popular packages and components generally recommended for Python in Emacs that provide auto-completion functionality.
I loosely used this post as a guide to do the setup on my Windows machine with Emacs 23.2.1 and Python 2.6.5. Although, I also have Cygwin installed in some cases instead of running the *nix shell commands mentioned in the post, I just download the packages via a web browser, unzip them with 7zip, and copy them to my Emacs' plugin directory.
Also, to install Pymacs, Rope, and Ropemacs, I used Python's EasyInstall package manager. To use it, I downloaded and installed the setuptools package using the Windows install version. Once installed, at the command line, cd to their respective download locations and run the command
easy_install .
instead of the shell commands shown in the post.
Generally, I saved any *.el files in my ~\.emacs.d\plugins (e.g. in %USERPROFILE%\Application Data\.emacs.d\) and then updated my .emacs file to reference them as documented in the post.
Despite all this, on occasion, I've used DreamPie since it does have overall better auto-completion out of the box than my Emacs setup.
I'm spoiled by Intellisense too. The PyDev extensions for Eclipse offer a pretty good auto-complete substitute.
I find that PyDev + Eclipse can meet most of my needs. There is also PyCharm from the Intellij team. PyCharm has the added advantage of smooth integration with git.
I've been using PyScripter, an IDE for Windows, for a while now, and have found it very good. It has autocompletion among many other features. It's written in Delphi -- not that there's anything wrong with that -- it just bothers me a bit, though...
Take a look at Spyderlib, support most of the features including code completion
IMO, by far the easiest way to take advantage of the python tools available for emacs is to take advantage of the defaults that are all set up at:
https://github.com/gabrielelanaro/emacs-for-python
I actually took the time to get pymacs and ropemacs and python-mode all working independently before finding that little gem, and now I rely on it entirely for all my python based customizations. If you are new, I would definitely start there.

Using pydev with Eclipse on OSX

I setup PyDev with this path for the python interpreter
/System/Library/Frameworks/Python.framework/Versions/2.5/Python
since the one under /usr/bin were alias and Eclipse won't select it. I can run my python script now but cannot run the shell as an external tool. The message I get is
variable references empty selection ${resource_loc}
Same if I use {container_loc}
Any thoughts ?
Sunit
I installed the Python.org version as well, this is a must.
I finally got PyDev working in Eclipse by pointing the interpreter to:
/Library/Frameworks/Python.framework/Versions/2.6/bin/python
manually. If you don't do it manually (by using the Autoconfig) it seems to not find the right version.
Common practice seems to be to install an up-to-date Python 2.5 from python.org and use that instead of the system installation. I saw that recommended here and there when I got started on Mac OS X.
It installs under /Library (as opposed to /System/Library) so the system Python is intact. Pydev has /Library/Frameworks/Python.framework/Versions/2.5/Resources/Python.app/Contents/MacOS/Python as its configured Python interpreter and all is well.
Can't state for sure that your trouble is due only to using the system's Python installation; in any case this way I have no trouble. Also, this way when you fiddle with your development environment (install things in site-packages, upgrade Python), anything that uses the system Python is sure to be unaffected.
I know this is a ancient post... but, in case of some newbee like me to get the better answer.
I just using "Eclipse Marketplace" from the "Help" menu and search for keyword "python" or "PyDev" to get PyDev, and get it successfully installed.
AND, you should add PyDev to the top-right dock.
For the instance, my eclipse on my laptop's OSX is (Version: Indigo Service Release 2 Build id: 20120216-1857).
Have fun, folks! :)
I believe ${resource_loc} or ${container_loc} (without any argument) are based on the current selection in your workbench when you are launching your script.
So are you selecting the right resource when selecting that script through the "external tool" runner ?
At least, click on the project name before you run one of the external programs.
Note: it works with a selection in the Navigator or Package Explorers views (the latest might not be available in PyDev environment though)
