using ipython with leo and python2.6

[John Griessen]

I've found how to test run leo with ipython OK. The leo build and
ipython are called using python2.6.

Now can I deal with python code that only works with python2.5 as
my ipython runnable script? In other words can the python called
by lines of the leo-ipython edited script be python2.5?

Well, as far as I know, neither requires 2.6, you could just run them
under 2.5.

Might help to know what you are trying to do.

the build instructions for leo from bzr said python2.6 was needed,
so I used python2.6.

Can leo built with python2.6 really be run fine with python2.5?
How about ipython 0.10-2 debian package? The package
dependencies say: python (>= 2.5) recommended, so 2.5 is OK there.
If leo can operate with 2.5 while built with 2.6, that's the thing that
will simplify my next steps.

I'm wanting to use leo-ipython to make 3D models with pythonocc,
which compiles with python2.5 and the build for that isn't ready
for 2.6. PythonOCC is a python way to call functions of OpenCascade
to build up a model of something so it makes a workable model to cut real
material with. As you build up a python script, you check your results
for code correctness by running 3D viewers and observing functions
behaving OK with no errors. When you "see" you are done via 3D view programs,
you are done scripting in python, and ready to use that model to output
CAD data in different formats
that CAM programs can run on.

Well, I think the 2.6 was put in so Leo could be updated to run on 3.x
series python, you might have to grab a version of Leo before that
requirement and run it that way.

Was the IPython running okay for you?, 10-2 is a latter version then I
have used and I think that Ville mention that the 10 series had some
issues when used with Leo

Yes, ipython 0.9.x max is recommended for now.

It seems they are using the pythonocc package on lucid, so it should
work ok with python 2.6?

It will only build with 2.5. This is all confusing me -- builds of programming language
wrappers that can run later versions of programming languages connected with earlier version
of ipython... Yi!

Thanks for the recommendation.

Debian has:


# lenny (stable) (python): enhanced interactive Python shell
0.8.4-1: all
# squeeze (testing) (python): enhanced interactive Python shell
0.10-2: all

Will 0.8.4 ipython be OK?

At some point it was - not sure if it's anymore.

You could also try

I started following an example from ILeo_doc.txt where you
start leo and ipython together,
make a node of valid python and execute that code by alt+I
and found an error about tkinter. python-tk was installed,
so I quit leo, quit ipython, read some, and wanted to try leo again
and I just got errors.

The errors the second time were unrelated to the first
and gave me few ideas... Anyone else know what to do here?

I have a start script leo.sh

#!/bin/bash
/usr/bin/python2.5 /opt/leo/launchLeo.py "$@"

running leo.sh
or
/usr/bin/python2.5 /opt/leo/launchLeo.py
or
/opt/leo/launchLeo.py

all give the same message right away:

I found the difference was the python version.

/usr/bin/python2.6 /opt/leo/launchLeo.py starts leo just fine.

I compiled with 2.6 and it only runs with 2.6 now.

So, again, what is an acceptable combination of things to do?

run leo --ipython from python2.6 and it will be python2.6 in ipython, right?

I think I'll need python2.5 for pythonOCC. Need to ask them.

I changed python-tk to the 2.6.5 version and can do a push to ipython from leo now.

Following the ILeo_doc.txt example, when I push to ipython I get good output:

<3> 3
--------------------------------> print("hello")
hello
<5> 7
<7> 'HELLO WORLD'

So it's working well enough to try some pythonOCC now.

In case that requires python2.5, (I'm going to try with the assumption
I can get by avoiding the latest python2.6 extensions I don't know about),
What leo release would I go back to for python2.5?

If I would see errors about caching, my first action would be to
remove the whole ~/.leo/db and restart leo again. This might help
avoiding triggering caching logic.
