As I do not really like default Beamer themes1, I tend to rely on Context to build my slides. I’ve built a set of custom themes for use with Hans Hagen’s
pre styles as well as Thomas Schmitz and Aditya Mahajan’s simpleslides. The latter caused me problem when I tried to recompile older slides.
simpleslides “third-party” module has been updated recently (January, 2012) but I didn’t notice that until I got the following error message
! Undefined control sequence. l.223 \definenamespace
when trying to rebuild a series of lectures for an upcoming course and a short talk. I then found this thread which basically says there might have been a problem well before
simpleslides was updated on CTAN; but I haven’t noticed that problem anyway. I don’t really know what the problem is with the current version of
simpleslides. What I know is that I don’t have time to update all my themes and go deep inside MkIV arcane. So I was looking for a quick way to get my earlier versions work as they did in December.
Here is my very hacky solution to solve this annoying problem: Fetch previous versions of
t-simpleslides.tex from TexLive svn, and put this your
texmf local directory. In my case, on OS X 10.7.3, it happens to be
As I’m using Metapost to create colored background and the like, I also have to remember to enable system commands in TeX’s texmf.cnf (
/usr/local/texlive/2011/texmf/web2c/texmf.cnf) so that around line 499 I have
shell_escape = t
I know there are better ways to enable system commands, but I always forget about them (like for
It looks like
simpleslides may be replaced by a new MkIV module, complexslides. I’ve tested it and it works quite well with the dev version of ConText, although I got some strange errors due to the
visualcounter module which was apparently missing from my system (I installed it once, so I don’t know why I wasn’t able to find it again). Grab the latest version from Github, and put it where ConText can find it. My experimental version of Context sits in
~/context, so for me it is
then just update TeX’s database:
$ mktexlsr $ context --generate
Well, everything works now, but I am waiting for some more themes.
