Dear Sir,
I know I can get the creation date that way, but what I want is to display the
day and time inline in the graphic by metaposting the document and it auto
updates. I am randomizing the content; ie. changing the equations, but I am
using web browser only. I found in Alan Kennington's metapost drawings for a
differential geometry book and as I am learning metapost by copying/pasting
code, I wanted to see if I can get the date as he gets it. From his page:
http://www.topology.org/tex/conc/mp/
We can get the source
http://www.topology.org/tex/conc/mp/ps/x/1568982300.71.40.58.214/mp1.tar.bz2
And there is a makefile to create the metapost cookbook for the pictures in the
main book. He has several macros, one that I use but in TeX/LaTeX is
% Calculate the number of hours and number of minutes (24 hour format):
\newcount\inthour
\newcount\inthoursixty
\newcount\intminute
\inthour=\time
\divide\inthour60
\intminute=\time
\inthoursixty=\inthour
\multiply\inthoursixty60
\advance\intminute-\inthoursixty
% Text representations of hours and minutes (24 hour format):
\def\zmonth{\ifnum\month<10\relax0\fi\number\month}
\def\zday{\ifnum\day<10\relax0\fi\number\day}
\def\zhour{\ifnum\inthour<10\relax0\fi\number\inthour}
\def\zminute{\ifnum\intminute<10\relax0\fi\number\intminute}
Typesetting date/time (local) of this document:
{\tt \number\year-\zmonth-\zday\space\zhour:\zminute}.
I modified last line to
{\tt \number\year.\zmonth.\zday:\zhour:\zminute} or
\texttt{\number\year.\zmonth.\zday:\zhour:\zminute} depending on (TeX/LaTeX)ing
the document. I would like to use a macro like this but in a metapost
document. I am using Troy Henderson's Metapost Previewer
http://www.tlhiv.org/mppreview/
Since I am not allowed to install software on machines at work :( I am using
web browser to display problems for students.
The error is as follows:
<quote>
! Extra tokens will be flushed.
divide
l.15 \divide
\inthour60
</quote>
I would like to include the day and time inline for displaying directly on web
browser. I know in advance that I can use the viewers to get the date and
time, but I would probably have to use livecd/livedvd/liveusb to bypass the
restrictions :(
Is it possible to get the running time using a macro/set of commands like the
mpdemo.pdf book?
Best Regards,
Antonio
