[sage-support] Re: Cannot open the disk 'D:\Program Files\Sage\sage-vmware-4.1\disk.vmdk'
well, you probably just need to remove some stale locks. That is, somewhere on the VM, there is a place where files indicating "busy" status of a particular volume, so-called locks, are stored. On Windows hosts, they have .lck extensions. So you need to remove the one that is causing you the trouble. However, a VM reboot should have taken care of it.

I tried everything I could imagine: restarting VMWARE, inspection of the individual vdmk files, restarting the computer, ... It seems that I have to re-install Sage (for Windows). The problem is that by re-installing, I will loose all my notebook files. So, I want to save those files first! BUT HOW?

Hi Harald, thanks for the suggestion, I had thought of that too. It seems like a viable route.

Yes, I found out about \includeonly from [1] shortly after posting, and I think that's what I'll do in the short term (homework being due Thursday and all :).

Most documents are probably not so computationally expensive as the examples file (which has lots of plots).

Unless you can think of a simple way to add support for generating separate sage files per tex file (which would also require changing the way .sout files are included I guess?), it doesn't seem worth the trouble. I can't begin to read sagetex.sty, so I can't really evaluate what's a reasonable feature request. Thanks for your thoughtful response!

[sage-support] Problems with Tkinter during build of Sage 4.2.1
Dear Sage-support: I am trying to build Sage 4.2.1 from source on a Linux machine running SUSE Linux Enterprise Server 10 (x86_64). The build proceeds to the end, but I have a persistent problem with the build process failing to find the "bits" for Tkinter. I have seen your FAQ item which addresses the Tkinter problem in Sage builds, but I don't have access to the tcl developer library. It appears to be software which isn't Open Source, and it does not seem to be part of the SLED distro on my machine. Is there another work around to resolve this issue? What I find strange is that I can build Python 2.6 "stand-alone" from source on the same machine using the same version of gcc I used for sage, provided that I have the path to the tcl/tk libraries in the environment variable LD_LIBRARY_PATH. That doesn't work for the 'sage' build, nor does using LD_RUN_PATH. My main goal is to have access to the numpy/scipy/matplotlib tools, and I'm finding that building some of those pieces individually for a "stand-alone" python 2.6 isn't all that easy. It's attractive to use something like sage which relieves me of the burden of having to find and build all of the parts and pieces for a useful python environment. Also, I looked at the pre-built binary distros of sage, and there isn't one for SLED 10 -- the SuSE 11 version doesn't work on my system. I've included a little more system info below.

BTW, if your build tool is Latexmk [1] (which is included in TeXLive), I
wrote a "custom dependency rule" that makes it work intelligently with
SageTeX: put this into your .latexmkrc and it will run Sage as
necessary.
-
# a SageTeX custom dependency rule for latexmk
add_cus_dep('sage', 'sout', 0, 'makesout');
sub makesout {
my $oldmd5 = "x";
my $currentmd5 = (split / /,
`egrep -v '^( _st_.goboom|print .SageT)' $_[0].sage | md5sum`)[0];
open(INFILE, "$_[0].sout");
while () {
if (/^%([0-9a-f]{32})%/) {
$oldmd5 = $1;
}
}
if ($currentmd5 ne $oldmd5) {
system("sage $_[0].sage");
}
else {
print "md5sums for $_[0].sage and $_[0].sout match, not running Sage\n";
return 0;
}
}
-
I'm very much not a Perl person, so that may not be the best way to do
it, but it seems to work well.

If so, one could simply keep the master > document clean of sagetex references, and build each subdocument > separately. My first thought is, if you're talking about using a master document and compile times for your homework...you have way too much homework. :) I don't know about keeping the master document clean of SageTeX references, but by using \include, you can keep things separated, and you can even compile only part of the document using \includeonly. One thing you can do with SageTeX to make things go faster is to use the pause and unpause commands -- \sagetexpause and \sagetexunpause. Commands between those two don't get run when you run Sage on the .sage file. (SageTeX literally just comments those sections out in the .sage file.) Actually, with the stuff I've done, the most time-consuming part of running Sage on the .sage file is simply startup time. Once it starts executing the commands, it generally goes really fast, but starting Sage takes a while. I'll think about your per-file ideas, and about some kind of \includeonly stuff. Right now, though, it works document-wide. What would you like to see? Can you describe some commands or functionality that you would find helpful?

The main "problem" is, that you may happen to define a variable in the beginning and modify it later and in the end it is used. Therefore there is no mechanism to break this chain apart and everything you define lives along a full sage session. I don't know how far Dan's ideas are, but there is one immediate hack i can suggest you: Just create PDF files for each chapter and then stick them together using a PDF-merge tool. I haven't done it yet, but i guess it's simple to create one big pdf file merging several pdf documents.

I don't know much about Windows, but did you try restarting? That might release any stale file locks. (Don't worry, your data should still be there.)

[sage-support] sagetex: granular builds for large documents
Hi Dan, others using sagetex I'm experimenting with a homework workflow using sagetex. I'd like to make efficient use of resources, which seems to be a (the?) major deficiency with sagetex, especially with large documents. My initial thought was that by placing each problem in an included file, I could have my build tool generate individual problem_x.sage and problem_x.sout files only for problems with changes, and keep the master tex file as a simple list of includes. I see now that that can't work, however, at least with my limited knowledge of TeX tricks. So I'm asking the group for ideas. Starters: 1. Is it possible to have a master document that includes a bunch of complete subdocuments? If so, one could simply keep the master document clean of sagetex references, and build each subdocument separately. 2. Could sagetex be modified to work on a per-file level?

Hi, Sage fails to start. Does this mean that I lost all my notebook files? That would be very sad... Thanks in advance of a solution which save my files!!
