ConTeXt + MetaUML

ConTeXt + MetaUML

[Renaud AUBIN]

[-- Attachment #1.1: Type: text/plain, Size: 1446 bytes --]


Hi all,

Some times ago, I have discovered MetaUML via the MetaPost ML. As  a
consequence, I have tried to use it with ConTeXt... Here is the result:

Considering a VERY simple example:

\starttext
\startuseMPgraphic{xx}
input metauml;
Class.A("A")()();
drawObject(A);
\stopuseMPgraphic

\placefigure[here][fig:xx]{xx}{\useMPgraphic{xx}}
\stoptext

The compilation failed with:

>> clearboxes
! Isolated expression.
<to be read again>
                   ;
<scantokens> ...nsidefigure := false ; clearboxes;

<to be read again>
                   ;
endfig->scantokens.extra_endfig;
                                shipit;endgroup
l.125 endfig
            ;

Apparently, MetaUML is based on boxes.mp

(temp-mpgraph.mp (/usr/share/texmf-tetex/metapost/metauml/metauml.mp
HERE ====> (/usr/share/texmf-tetex/metapost/base/boxes.mp)
(/usr/share/texmf-tetex/metapost/metauml/util_infrastructure.mp
(/usr/share/texmf-tetex/metapost/metauml/util_log.mp))
....
....

It have already tried to use boxes.mp in ConTeXt in the past, but
switched for metaobj because:
1. metaobj is more suitable to my needs
2. boxes.mp causes troubles when used with ConTeXT

I'll keep searching a solution but if one of yours has already dealt
with this kind of problems and succeeded in using boxes or, best, MetaUML...

(I have to precise that I don't want to include a ps or pdf file
generated by metapost only. I would embed the code in my document)

Cheers,

Renaud

I remember I had such troubles when including boxes. It makes a mess when  
included in a graphic. Inluding it via \startMPinclusions makes your  
example work.

\starttext
\startMPinclusions
input metauml.mp;
\stopMPinclusions
\startuseMPgraphic{xx}
Class.A("A")()();
drawObject(A);
\stopuseMPgraphic

\placefigure[here][fig:xx]{xx}{\useMPgraphic{xx}}
\stoptext

can you grep your metapost tree for 'clearboxes'? where is it defined?

Hi Hans,

The example with clearboxes's crash:

\setupoutput[pdftex]

\starttext
\startuseMPgraphic{my_uml_figure}
input metauml;

Class.A("Point")
       ("+x: int",
        "+y: int") ();

Class.B("Circle")
       ("radius: int")
       ("+getRadius(): int",
        "+setRadius(r: int):void");

topToBottom(45)(A, B);

drawObjects(A, B);

clink(aggregationUni)(A, B);
\stopuseMPgraphic

\placefigure[here]{none}{\useMPgraphic{my_uml_figure}}

\stoptext

The resulting pdf looks good... strange...

I use teTeX on debian + metapost 0.901
renaud@rescue:/usr/share/texmf-tetex/metapost/base$ grep clearboxes *
boxes.mp:  expandafter def expandafter clearboxes expandafter =
boxes.mp:    clearboxes cl($);
boxes.mp:  & "boxjoin();save pic_,sproc_,pproc_;def clearboxes=enddef;";
boxes.mp:extra_endfig := extra_endfig & "clearboxes;";

Now, I have solved my problem with this (horrible!?) hack:

\startuseMPgraphic{my_uml_figure}
input metauml;
beginfig(1);
Class.A("Point")
       ("+x: int",
        "+y: int") ();

Class.B("Circle")
       ("radius: int")
       ("+getRadius(): int",
        "+setRadius(r: int):void");

topToBottom(45)(A, B);

drawObjects(A, B);

clink(aggregationUni)(A, B);
endfig;
\stopuseMPgraphic

I don't want to put "input metauml;" within MPinclusions because for my
PhD thesis, I have a lot of MPgraphic (without MetaUML) and:
1. I don't want to load metauml for each metapost run
2. I use MetaObj... (MetaUML and MetaObj interfere to each other)

Cheers,

Renaud

\setupoutput[pdftex]

\starttext

\startMPinclusions
 input boxes;
\stopMPinclusions

\startuseMPgraphic{my_uml_figure}
input metauml;

Class.A("Point")
       ("+x: int",
        "+y: int") ();

Class.B("Circle")
       ("radius: int")
       ("+getRadius(): int",
        "+setRadius(r: int):void");

topToBottom(45)(A, B);

drawObjects(A, B);

clink(aggregationUni)(A, B);
\stopuseMPgraphic

\placefigure[here]{none}{\useMPgraphic{my_uml_figure}}

\stoptext

this only works when in boxes.mp, we have:

extra_beginfig := extra_beginfig
  & "boxjoin();save pic_,sproc_,pproc_;def clearboxes=enddef;";
extra_endfig := extra_endfig & " clearboxes";

(space added before clearboxes in string)

(maybe i should clean up boxes.mp and preload that in metafun if only i 
know what it's meant for)

i suggest that you contact the author of metauml:

- rename the util_* files into metauml_util_* in order to prevent 
clashes with other util_* files
- load all files into the main file, so that you get rid of the 
redundant file reads (loading  quits when the files are already 
loaded,but best do some testing before they are input)
- provide a metauml_preload.mp file that preloads e.g. boxes.mp so that 
you can do

\startMPinclusions
 input metauml_preload;
\stopMPinclusions

\startuseMPgraphic{my_uml_figure}
input metauml;
\stopuseMPgraphic

- provide "load_metauml" that loads once only, so that you can do

\startMPinclusions
 input metauml_preload;
\stopMPinclusions

\startuseMPgraphic{my_uml_figure}
load_metauml;
\stopuseMPgraphic

\startuseMPgraphic{my_second_uml_figure}
load_metauml;
\stopuseMPgraphic

and get only one load when you collect graphics instead of runtime 
processing

Hans

Hi all,

Ovidiu Gheorghies has sent to me an intermediate-release yesterday, I'll
test it and if same problems occur I'll try to modify the metauml
structure by myself in interaction with Ovidiu (according th Hans's advice).

I'll do that as soon as I have the time... ;)

Cheers,

Renaud
