Hello Simon,
thank you very much for this explanation. I think this is a very nice
feature and this should be made more
visible when promoting sage. Also I found your explanation more
helpful than the tutorial, maybe this text can be replaced :-)
At least I have struggled to build various tools on a Linux
installation, and it takes a lot of time to get R, Maxima, Python with
libraries working correctly. And this already exists in Sage, well
tested and stable! That could save a lot of time for many people.

For example: I have a directory bin/ in my home directory, that also
is in my PATH. Once upon a time, I did
sage: install_scripts('~/bin/')
In principle, you could name any directory to which you have write
permission. In that directory, Sage creates a couple of scripts: gap
gp hg ipython maxima mwrank R singular
There is not much magic in the scripts. For example, the "gap" script
is
#!/bin/sh
sage -gap $*
Hence, if I do
gap
in a shell, then in fact "sage -gap" is executed; so, it uses the gap
shipped by Sage, but it doesn't start Sage.
Apparently the scripts don't need to change if the Sage-gap, -
singular, -gp,... versions change. Hence, when I say "once upon a
time", it was really only *once*.
Remark: You ask if it is possible to make "python or R" available. I
don't know if it is possible to ask the install_scripts function to
*only* install python and R but nothing else. Also I notice that there
is no script called "python" in the list above; but it would of course
be easy to write such script.

Sorry, that post is beyond my knowledge. I even don't know if it is
related.
Cheers,
Simon

I looked at http://www.sagemath.org/doc/reference/sage/misc/dist.html but somehow the usage is not clear to me? I also ask because i think this would be a very interesting feature.

Make symlink to the python which is contained in sage to use it from outside? Thats how I did in the sage live CD. So you save space and you can use all libraries (numpy, sympy ... ) which are already contained in the sage python. emil -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

Hmm, you are right, I might break something if I don't stuck in 2.6... All right, thank you very much anyway.

It's possible and done for some linux distributions, but I don't think it's a good idea for you. You can look into Sage's local/lib/python2.6 folder, where you can see that you can only save about 40MB (all the rest is in the site packages which are part of sage anyways). Also, Sage is only tested to work well with the given python version. That might not be true for other ones, because some libs directly access python internal datastructures that might be subject to changes and so on. Rather, you could go the other way round and use "sage -python" as your python interpreter or work inside the "Sage Environment" via $ sage -sh ... depending on what you want to accomplish.
