Hi all, Yesterday, I have tried to put "\input boxes" within a MPgraphic. As a result, I obtain errors at compilation. After discussing this issue with Taco on #context, it appears that boxes.mp and metafun interaction is not safe at all. Ok, but since my needs remain the same, solutions are : 1. just do it, but manually (not smart at all) 2. use metapost then include the result in my document through ps or pdf files (this solution needs the user takes care of fonts + manually metaposting -> not "really" smart) 3. use charts (but depends on what you want achieve -> ok, but not for all purposes) 4. define some metafun macros (time consuming at the beginning but it's best to invest for the long term) X. others solutions I don't know yet... (feel free to add yours !) My thought is to finally obtain in metafun: 1. Nodes with text (multiline text!) and a collection of "simple" shapes to use like box, circle, box with rounded corner... 2. Nodes must be placed freely accroding to the metapost coordinate system 3. Connections between nodes (using boundaries of each nodes + possibility to give angles from...to for each connections) PSTricks can do that but it can be nice if metafun can provide this kind of features. See http://renolab.lrv.uvsq.fr/perso/ConTeXt/sample.png to have an idea (nodes are aligned in this figure but it is a particular case)... Maybe a solution exists, but since I don't know it, I send this post: 1. Are other people interested ? 2. What is the best solution to implement this feature in metafun ? My idea is to use \framed + shapes + path + ... Feel free to give your opinion/need/contribution/whateveryouwant.... ;-) Cheers, Renaud

Hi all,

Shouldn't that be input boxes; in a MPinclusions?
X. others solutions I don't know yet... (feel free to add yours !)
Have a look at metaobj.
My thought is to finally obtain in metafun: 1. Nodes with text (multiline text!)
Place inside a framed
and a collection of "simple" shapes to use like box, circle, box with rounded corner...
Metaobj provides all basic shapes
2. Nodes must be placed freely accroding to the metapost coordinate system
Metaobj provides a better interface to placement. You can specify the distance and alignment between the nodes.
3. Connections between nodes (using boundaries of each nodes + possibility to give angles from...to for each connections)
Has all of that
See http://renolab.lrv.uvsq.fr/perso/ConTeXt/sample.png to have an idea
See the example below. metaobj has some bugs and limitations, but works as expected most of the time. \starttext \startMPenvironment \setupbodyfont[8pt] \setupframed[width=3cm, align=center, frame=off] \stopMPenvironment \startMPinclusions input metaobj; setObjectDefaultOption("Ellipse")("fit")(false) setCurveDefaultOption("arcangleA",15); setCurveDefaultOption("arcangleB",15); \stopMPinclusions \startMPpage % Metaobj provides a Circle command. But there seems to be % a bug in the interaction of Circle and Matix. So using Ellipse with % fit=false newEllipse.N1(btex \framed{Mise Sous Tension} etex) ; newEllipse.N2(btex \framed{Mesure du point zéro méchaique} etex) ; newEllipse.N3(btex \framed{Régalage des paramèters de contrôle} etex) ; newEllipse.N4(btex \framed{Envoi du contenu de l'\cap{EEPROM}} etex) ; newEllipse.N5(btex \framed{{\bf Mode stop|/| réglage} Attente de commande} etex) ; newEllipse.N6(btex \framed{\bf Mode freins libres} etex) ; newEllipse.N7(btex \framed{Le contenu de l'\cap{EEPROM} a changé} etex) ; newEllipse.N8(btex \framed{Ëcriture du contenu de la \cap{RAM} vers l'\cap{EEPROM}} etex); newEllipse.N9(btex \framed{{\bf Mode Contrôle} La valeur de la commande est rafraîchie à chaque cycle} etex) ; newMatrix.diagram(3,3)(N1,N2,N3,N4,N5,N6,N7,N8,N9) "hsep(1.5cm)", "vsep(1.5cm)"; diagram.c = origin ; drawObj(diagram) ; ncline(N1)(N5) ; for i = 2,3,4,6,7,8,9: ncarc(N[i])(N[5]) ; ncarc(N[5])(N[i]) ; endfor nccircle(N6) "angleA(-120)" ; nccircle(N9) "angleA(-120)" ; % Labels can be added.

Hi Adita, I have already seen metaobj in the past... but I have forgotten it... ;-) Thank you very much for the example ! Cheers, Renaud
