[sage-support] Re: problem with installation ??
Dear Julien, Thank you for trying Sage. You appear to be using a rather old version, and it is usually very easy to download a newer one. Can you give us some more specific information about what version it is, where you downloaded it, what OS you are on, and so forth? What seems to be happening is that there is a simplification called which has done something grotesque, giving an error that usually happens with unmatched parentheses and the like. With more info, this might help us track down why this is happening to you. Also, if you can do sage: 2+2 4 that is a good sign! What happens if you do the following? (It should bring up a new subprogram, which you can quit with Ctrl+D.) sage: maxima_console() Thanks, and hope we can help you! - kcrisman On Aug 4, 12:31 pm, julien julien.d...@gmail.com wrote: Hello, I am completely new to Sage.. but I am so excited, it looks like the ultimate tool !!!

[sage-support] Re: SageTeX compiling errors in TeXShop
That works! I had followed the more permanent instructions previously, but somehow the wrong version still ended up in the right place. Anyway, it works now, even the automatic compiling in TeXShop. The only thing that is still acting funny is when I compile the example that came with SageTeX, but that doesn't really matter. It compiles sometimes, but not others, and when it doesn't, it gives me a variety of errors in TeXShop (when it's compiling the tex!). Like I said, oh well. If I have trouble later on with one of my personal documents, I'll repost. Thank you for all of your help! :) ~Katie On Aug 2, 9:32 pm, Dan Drake dr...@kaist.edu wrote: Hi Katie, Sorry for the slow replies. I'm traveling and have not been keeping super current on email.

I copied his code into a file, ran it in TexShop and got no errors, but did get a warning: [...] (/usr/local/texlive/2009/texmf-dist/tex/latex/sagetex/sagetex.sty I think that is one problem: your TeX installation has one version of SageTeX and your Sage or TexShop installation has another. The versions need to match in order for things to work, and I've put code into SageTeX that will check for that, but you seem to have a slightly older version. Try this: open a terminal, and move the above file somewhere else, with something like: cd /usr/local/texlive/2009/texmf-dist/tex/latex/sagetex sudo mv sagetex.sty old-sagetex.sty That will move the old sagetex.sty file (which is what TeX needs to understand SageTeX stuff) out of the way. Now you will need a new copy of sagetex.sty, one that matches the SageTeX stuff built into Sage. Here's one way to do that: find where you installed Sage; call that directory SAGE_ROOT. Then, in a terminal, do this: cp SAGE_ROOT/local/share/texmf/tex/generic/sagetex/sagetex.sty YOUR_DOC where, of course, you replace SAGE_ROOT as above and YOUR_DOC is the directory where your sample document is. Then try typesetting your document and running Sage again. Does that work?

[sage-support] Re: problem with installation ??
Thanks so much for the quick help !!! I am running sage on ubuntu, First I downloaded the version from the package installer in ubuntu. (Synaptic package manager, package sage) and because I had troubles, i decided to download the lastes version for ubuntu on the website of sage. (but I am not so sure which of the two versions I am actually running now, I guess the second one, if i did the install procedure correctly [I copied the directory in /opt/ nad then made a symbolic link with the ln command]) but still the same problem. it appears to be version 3.0.5, see bellow also the test.

[sage-support] Organizing Worksheets in subfolders
Hi, is there a way to creat subfolders in the Notebook environment? Over the time most SAGE users will (probably) have a lot of worksheets and I would like to know if you could organize them in any useful way. I know there is the Archive option, but it seems this just moves active worksheets to the archive (which again becomes a long list after a while). Would be nice to have something like subfolders available, but I have not seen such a thing.
