Re: [sage-devel] Re: Delete old optional packages

[Alejandro Serrano Mena]

Dear all,
I was the uploader of the `sip` and `PyQt4` packages. This was long ago and 
right now I cannot take the effort of upgrading them. As far as I know, 
they haven't been used for any other thing that experimentation...

QT and PyQT are standard Ubuntu packages. You need both installed to run the
QT environment. However you also need a version of PyQT (and only PyQT, not
QT) compiled under the Sage environment (so it would be installed inside the
bin, lib and those folders inside the Sage folders)

I use the facilities available in Python. Each worksheet has an associated
thread where all the work happens. Each worksheet also saves the state of
the variables. When the user wants to execute any code, it is precompiled
from Sage to Python code, then the Abstract Syntax Tree is manipulated so
the result of the last line of code could be recovered, and then that code
is basically executed via exec.

I was using Ubuntu 9.04 and currently I'm using Ubuntu 9.10, with the latest
components of SIP, PyQt and PyQScintilla.
For Qt, a version 4.5 or greater is needed (because the WebKit component
used to render the outputs is not available in previous versions). You also
need PyQt4 with the same minor version as your Qt installation (that is, if
you have Qt 4.5.1 in your system, you need PyQt 4.5.x for it to work).

Sure! I'm uploaded them into the Sourceforge site:
https://sourceforge.net/project/screenshots.php?group_id=287015
It shows the current features: autocompletion, variable explorer, graph
viewer, plots...

As of now you cannot save a worksheet. The idea is double:
- First of all, use the same sws format as the notebook, so files would be
completely interoperable
- Be able to connect this Qt frontend to a running instance of Sage Notebook
and directly use the files from there. In that way we could get automatic
revisions, sharing... that Sage Notebook has.

Yes, the compatibility would be a great idea!
As for the name, I've been suggested by a friend to use "+Sage", which is
Spanish is read "masaje" which means massage. But any other name is great
for me :)

For the future, what do you think would be the best way to allow people to
write entire Sage code files inside the environment and then test them with
the QT Notebook? Has Sage got any facility to load Sage files dinamically (I
don't know whether using a plain import works)?

It usually means that you need to install libqscintilla2-dev and libqt4-dev,
so development files are used.

[sage-devel] Lorien Labs: an IDE for Sage

[Alejandro Serrano Mena]

Hello,
For the past few months I've been working on a prototype of an Integrated
Environment for developing and running Sage. I decided to start the project
for mainly these reasons:
- There is no environment for developing Sage programs or libraries:
nowadays the Notebook is not the best option for those taks
- Allowing Sage to run in local environments: that means that we can have
more information that the Notebook provides: better completion, using
functions between different files...

As of now you can download the code with "svn co
https://lorienlabs.svn.sourceforge.net/svnroot/lorienlabs/trunk lorienlabs".
The only problem is that PyQt4 is neccessary, but must be compiled inside
the Sage environment. I've uploaded instructions on how to do this in
"doc/readme" in the SVN repository.

Lorien Labs (the name has to be changed, I know) now only emulates notebook
worksheets, with an added docklet to show the variables in a sheet and their
contents. It also includes a preview of how a new viewer can be added to the
program with a graph viewer (type graphs.DodecaedralGraph() and press Shift
+ Enter to see what I'm talking about). I'm currently planning how to add
support for Sage code files, with autocompletion and so on, and how a
worksheet may access the functions on those code files.

Any suggestion and help is welcome :) I hope you like it.

Alejandro
