Getting started? virtualenv?

[Dan Connolly]

I ran across spyder recently, and the combination of features looks
pretty nifty.
http://code.google.com/p/spyderlib/wiki/Features

In particular, code completion.

I have an existing python project, maintained with the usual setup.py
and virtualenv.
http://informatics.kumc.edu/work/browser/raven-j

How can I use Spyder to edit it with code completion?

The project explorer docs say it can "import from existing Pydev
(Eclipse) or Spyder projects."
http://packages.python.org/spyder/projectexplorer.html

But I don't have an existing pydev or spyder project; so what do I do?

What does File/New Project do? Is that only for completely new
projects, or can I use
it to start working with my sources?

How does the PYTHONPATH manager relate to virtualenv?

p.s. I'm on freenode in #swig as DanC. If any other spyder users are
on freenode
and available to hold my hand a bit, please suggest a channel where we
can chat.

Hi, Dan

From that I can see, Virtualenv is not supported natively by Spyder. But it would be a good addition, indeed. It should not be too hard to add 'execute script in virtualenv' option to 'run' dialog.

I guess Spyder needs to be extended to import simple directories also. In fact, if you have project in 'project explorer' and then click on any project - there is a menu that allows to Import existing directory. I wonder why there are no such option in File menu? Looks like a bug to me.

As the last resort just open your files and start hacking.

That's for the new projects, but it would be convenient if import capabilities were merged into this menu also. Could you add an item for that to tracker?

How does the PYTHONPATH manager relate to virtualenv?

I have no idea how virtualenv sets PYTHONPATH and where does it save the settings. This had to be researched.

Hi Dan,

I'm sorry to contradict Anatoly, but Spyder has support for virtualenv.
You can go to:

Tools > Preferences > Console > Advanced Settings > Python Executable

and there you can select the path to the python interpreter of your
virtualenv, e.g something like:

/home/carlos/.virtualenvs/visual/bin/python

if you use virtualenvwrapper as me. After this, you have to click in:

Tools > Update module names list

to update a little database we maintain of the module names in your
PYTHOPATH, so they can be TAB-completed.

A project in Spyder is a tree-like view of your sources dir and saves
some setting as your preferred PYTHONPATH for it. In version 2.1 it can
also let you import and existing dir.

Please let us know if you need any additional help.

Cheers,
Carlos

Not really a contradiction. I searched the source and couldn't find any
references. If we support virtualenv's, this should be mentioned
somewhere.

I see. I thought `virtualenv` should be activated prior to calling
Python, but it seems like interpreter from `virtualenv` directory will
use the appropriate environment automatically. Anyway, the option
seems to be global, not something project-specific.

Nice!

I don't see a "Python Executable" under Advanced Settings.

I took a screenshot of what I see:

Dan , you need to install the latest stable version, i.e. Spyder 2.1.1,
to have this functionality.

I would like to ask you something else: in your first mail you said:

What do you exactly mean by "the usual setup.py and virtualenev"? We
would like to understand better the workflow of our users so we can
improve some code completion features.

Cheers,
Carlos

Probably something with setuptools that requires `python setup.py
develop`, like Trac
http://trac.edgewall.org/wiki/TracDev/DevelopmentEnvironmentSetup

I have a good idea to improve development workflow with Spyder, but it
requires some Qt knowledge and 'slightly' more time than I can afford to
prototype it before the New Year. We can discuss it separately if there
is an interest.

I was afraid of that.

2.1.1 doesn't seem to be available as an Ubuntu package yet.
https://launchpad.net/ubuntu/+source/spyder

Here's hoping I find time to build it from source.

I gave it a quick try and failed:

~/src/spyder-2.1.1$ python setup.py develop
Traceback (most recent call last):
File "setup.py", line 16, in <module>
from sphinx import setup_command
ImportError: No module named sphinx

I'm sure the fix for that is straightforward, but one never knows how
long the string of dependencies is...

Yes. In particular, mine is a pyramid project
http://docs.pylonsproject.org/projects/pyramid/1.2/narr/project.html

but perhaps the canonical documentation for "the usual setup.py
and virtualenv" is from pypi:

"Package Authors

To submit a package use "python setup.py upload" (full tutorial)."
-- http://pypi.python.org/pypi

which takes you to http://wiki.python.org/moin/CheeseShopTutorial
and then to http://docs.python.org/distutils/setupscript.html

FYI, I've just found out about the following related bug:
http://code.google.com/p/spyderlib/issues/detail?id=826&colspec=ID%20Cat%20Type%20Status%20Priority%20Milestone%20Owner%20Summary&start=100

I've already fixed this in my local repository. I'll push changes
ASAP.
