Using metapost figures in context

Using metapost figures in context

[Aditya Mahajan]

Hi,

  Does there exist a startstop command (say startMPfigure) for managing 
figures drawn using MP such that

1. I can use \startMPfigure{label} ...... \stopMPfigure and then use
\useexternalMPfigure{label} to include the figure.

2. The figures are converted into pdf once. If the code inside 
\startstop MPfigures changes, the pdf for each figure is recreated.

Basically, I want MPfigures to be converted into pdf for faster 
inclusion in the main document, the figure should be recompiled if 
necessary and I should be able to include the figure using a label 
(so that I can separate the figures from the main document).

uniqueMPgraphic provides the first functionality, but the figure is 
converted into pdf on runtime (thereby increasing the processing time 
of the document).

I can use a separate document with each figure inside a \startMPpage 
... \stopMPpage, but (i) I need to remember figure numbers manually, 
(ii) after making change in one figure, the whole file needs to be 
recompiled.

Another possibility is to use one tex file for each figure, compile 
them separately and then then use figure library to get a "label" for 
each figure. But this becomes difficult to manage, as soon as I get 
large number of files.

Is their something basic that I am missing here? How do others manage 
mpfigures?

To Hans: is it possible to have a \startMPfigure command such that

1. \startMPfigure[label]
      figure code
    \stopMPfigure

creates a \jobname-figure-\nofMPfigurefile file with

current MP environment
current MP inclusion
figure code (from inside \startstop MPfigure)

Convert this into \jobname-figure-\nofMPfigurefile.pdf only if 
something changes (similar to what is done in m-r module).


2. The resultant pdf can be included using \useMPfigure{label}.

Would such a feature make sense?

you can use the figure database mechanism (davids arnold does that)

or make individual files,  say 'thatfile.tex'

\starttext \startMPpage
  fill fullcircle scaled 10cm;
\stopMPpage \stoptext

and then in test.tex say:

\def\MyMpgraphic[#1]%
  {\executesystemcommand{texmfstart --ifchanged=#1.tex texexec #1.tex}
   \externalfigure[#1.pdf]}

\starttext

\MyMpgraphic[thatfile]

\MyMpgraphic[thatfile][width=3cm]

\stoptext

(you need a version of texmfstart that provided the -ifchanged)

Thanks! This was almost what I needed.

I have a simple version using this idea that is working. See at the 
end.

Did not think of that. Was too busy trying to figure out how to do 
number to label mapping :)

I have right now kept the command as MPfigure.

The following works, but I can not figure out

1. How to force texexec to give pdf output from an mp file. Do I need 
to start another mptopdf process?

2. How to get textext to work?

3. I needed to set randomseed to false. Does this have any drawbacks? 
supp-mps.tex says that this feature is optional. Does metapost have a 
good random seed initializer now?

\def\startMPfigure#1#2\stopMPfigure
   {\bgroup
     \setMPrandomseedfalse
     %Otherwise randomseed := number line always differ

startMPrun not check for textext. Consider

% \forceMPTEXgraphictrue
% Does not make a difference!

\starttext
\startMPrun{testmp}
   beginfig(1)
   drawarrow (0,0)--(1cm,0) ;
   drawarrow (0,0)--(0,1cm) ;
   label.llft(textext("(0,0)"),origin) ;
   endfig;
\stopMPrun
\externalfigure[testmp.1]
\stoptext

which gives the dreaded "unknown" string, while

\starttext
\startMPgraphic
   beginfig(1)

   label.llft(textext("(0,0)"),origin) ;
   endfig;
\stopMPgraphic
\externalfigure[\jobname-mpgraph.1]

works.

I can get my previous macro to work for textext using startMPgraphic.

\def\startMPfigure#1#2\stopMPfigure

     %Otherwise randomseed := number line always differ

\def\useMPfigure{\dosingleempty\douseMPfigure}

\def\douseMPfigure[#1]%

\starttext

\startMPfigure{circle}
   fill fullcircle scaled 10cm;
\stopMPfigure

\startMPfigure{axis}
   drawarrow (0,0)--(1cm,0) ;
   drawarrow (0,0)--(0,1cm) ;
   label.llft(textext("(0,0)") ,origin) ;
\stopMPfigure

\hbox to \hsize  \bgroup
\hss \useMPfigure[circle][width=1cm] \hss \useMPfigure[axis] \hss 
\egroup
\stoptext

Right now I have a big speed improvement as metapost is not executed 
each time. I only need to convert the mps files to pdf to save a bit 
on pdf conversion.

I added to texexec:

texexec --mpgraphic somefile.mp

which will run mp and make a pdf file.

when more graphics are in the file, names become somefile-1.pdf etc 

one can always say:

\useexternalfigure[whatever][somefile-123.pdf] 

to have more symbolic names

actually, the problem is that the latest pdfetex is not called pdftex; can you remove all traces or pdftex[.exe] in your bin path and see what happens then?

No pdftex is in the path.

I call context by using
set PATH=E:\Ruby\bin
call E:\isoimage\usr\local\context\tex\setuptex.bat E:\isoimage\usr\local\context\tex

so there should not be any mismatched executables.

ah ... typo in base/tex.rb:

    @@pdftex     = 'pdftex' # new default, pdfetex is gone

    ENV['PATH'].split(File::PATH_SEPARATOR).each do |p|
                                     ^^^^^^^^^^^^^^^^^^^^^^

Can you test that?

Yes, this works. The formats are generated correctly. However,
texmfstart texexec --mpgraphic file.mp

does not give me a pdf file. I do understand why this is happening. I 
will dig into it a bit more and see what is going wrong.

In tex.rb

  def processmpgraphic
  ...
      if data =~ /output files written\:\s*(.*)$/mois then
  ....

However, if the mp file contains only one figure, the output in the 
log is

1 output file written: figures-axis.1

Notice /file/ instead of /files/. So the regex should be changed 
according. Then everything works.

That does the trick. --mpgraphic is working correctly. However, there 
is no message on the console saying that a pdf file is created. Can 
you add
   report ("{#name}.#{number} converted to #{filename}.#{number}.pdf")
and
  report ("#{name}.#{number} converted to #{filename}.pdf")

after File.silentrename lines.

Now I am using staticMPfigure. This is the final version

\def\startstaticMPfigure#1#2\stopstaticMPfigure

     \setMPrandomseedfalse
     %Otherwise randomseed := number line always differ

\ifcase\interactionmode\MPOSTbatchswitch\or\MPOSTnonstopswitch\fi
       \space\ifuseMETAFUNformat \MPOSTformatswitch metafun \fi ##1}
    \def\executeMPTEX##1% slower, due to nested texexec call
    {texmfstart --verbose --ifchanged=##1.mp texexec
        --batch \ifcase\interactionmode --logfile='mptex.log' \fi
        --output=\MPOSTdriver\space
        \ifuseMETAFUNformat --mpformat=metafun \fi --mptex --nomp 
--once ##1}}
     \def\MPgraphicfile{\jobname-#1}
     \newcount\currentMPgraphic
     \startMPgraphic
       #2
     \stopMPgraphic\egroup\deallocateMPslot\currentMPgraphic}

\def\usestaticMPfigure{\dosingleempty\dousestaticMPfigure}

\def\dousestaticMPfigure[#1]%
   {\doifmodeelse{*pdf}
   {\externalfigure[\jobname-#1.pdf]}
   {\externalfigure[\jobname-#1.1]}}

\starttext

\startstaticMPfigure{circle}
   fill fullcircle scaled 10cm;
\stopstaticMPfigure

\startstaticMPfigure{axis}
   drawarrow (0,0)--(1cm,0) ;
   drawarrow (0,0)--(0,1cm) ;
   label.llft(textext("(0,0)") ,origin) ;
\stopstaticMPfigure

\hbox to \hsize  \bgroup
\hss \usestaticMPfigure[circle][width=1cm] \hss 
\usestaticMPfigure[axis] \hss \egroup

I am no ruby programmer, but although the above works, it should be
                  if data =~ /output files? written ...

well, s* means zero or more s's so we also catch future typos in metapost, i.e. output filesssss -)
