scaling reusableMPgraphic & some ConTeXt programming

scaling reusableMPgraphic & some ConTeXt programming

[Mojca Miklavec]

Hello,

the answers to these three questions are most probably one-liners, but
I don't know which ones ;)

1. How can I scale (an already defined) reusableMPgraphic? Simplified
example of what I currently (want to) have:

% how should I change this definition?
\def\usemygraphic[#1][#2]{\reuseMPgraphic{#1}}
\usemygraphic[name][width=.7\textwidth]


2. I have several graphics defined as

\startGNUPLOTgraphic[1][name]
	draw fullcircle scaled 3cm withcolor .625red;
\stopGNUPLOTgraphic
\startGNUPLOTgraphic[2][name]
	draw fullcircle scaled 3cm withcolor .625green;
\stopGNUPLOTgraphic
\startGNUPLOTgraphic[3][name]
	draw fullcircle scaled 3cm withcolor .625blue;
\stopGNUPLOTgraphic

\startGNUPLOTgraphic[1][othername]
	fill fullcircle scaled 3cm withcolor .625red;
\stopGNUPLOTgraphic
\startGNUPLOTgraphic[2][othername]
	fill fullcircle scaled 3cm withcolor .625green;
\stopGNUPLOTgraphic

and a pretty stupid definition:

\long\def\startGNUPLOTgraphic
	{\dodoubleargument\dostartGNUPLOTgraphic}

\long\def\dostartGNUPLOTgraphic[#1][#2]#3\stopGNUPLOTgraphic % [number][name]
	{% add to counter to note the nuber of the graphic
         % define a new counter for the first time when you use it
	 \doif{#1}{1}{\doglobal\newcounter\abc}% counter name has to depend on #2
	 \doglobal\increment\abc % assigning the value #1 to it would also be OK
	 \startreusableMPgraphic{gpg:#2:#1}#3\stopreusableMPgraphic}

How can I give a better name than \abc to the counter (the name should
depend on #2 in order to be unique)?


3. I would like to change \usemygraphic, so that
\usemygraphic[othername] or \usemygraphic[othername][height=5cm] would
resolve to
    \dorecurse{2}{\useMPgraphic{gpg:othername:\recurselevel}}
and \usemygraphic[name][n={1,3},width=8cm] (syntax might be different
if necessary) to
    \reuseMPgraphic{gpg:name:1}
    \reuseMPgraphic{gpg:name:3}
(with proper scaling if possible).

How should I start?

Thank you a lot for any hints,
    Mojca Miklavec

Guessing:

   \def\usemygraphic[#1][#2]{\scaled[#2]{\reuseMPgraphic{#1}}}

Better use \definenumber instead of the low-level command.

Where does this '2' come from?

Create a commalist of desired numbers first (possibly using recursion),
then run \processcommalist on each item.

\usempgraphic[name][width=4cm,height=5cm]

\scale accepts the same scaling options as externalfigure

why do you need a counter

\long\def\dostartGNUPLOTgraphic[#1][#2]#3\stopGNUPLOTgraphic
  {\startreusableMPgraphic{gpg:#2:#1}#3\stopreusableMPgraphic}

you want all graphics?

\def\usemygraphic#1%
  {\doloop
     {\doifMPgraphicelse{gpg:#1:\recurselevel}
        {\reuseMPgraphic{gpg:name:\recurselevel}}
        {\exitloop}}} 

or so ...

Thanks to both you and Taco!

Wow! No, I don't need a counter in that case ;)

Just a little detail: Yes, I want all the graphics except if the user
provides "n={1,3}" or "n=4", then I would like to output only the ones
specified. I know that this is a trivial question, but how do I
extract the argument of "n=..." to \processcommalist on it?

And yet another short&stupid question: when does \c!something=\v!value
work? I tried to change \setupGNUPLOT[terminal=context] into
[\c!terminal=\v!context] (in \unprotect-ed area), but I get a
command-undefined error.

Thanks,
    Mojca

depends on how you store it (say in requestedlist), anyhow testing is simple



\def\usemygraphic#1%
  {\doloop
     {\doifMPgraphicelse{gpg:#1:\recurselevel}
        {\expanded{\doifinset{\recurselevel}{requestedlist}}{\reuseMPgraphic{gpg:name:\recurselevel}}}
        {\exitloop}}}


or so

only predefined key/values (in mult-con) are stored in their efficient ! form (and get translated when needed)

Thanks. I never understood what
    \def\c!first     {first}
    \def\c!last      {last}
    \def\c!quotechar {quotechar}
was doing in m-database.
