tikzpicture in margin

tikzpicture in margin

[Jigé]

Hi all.

I'm trying to place a TikZ picture in the margin.
Here is a small example:

\usemodule[tikz]
\setuplayout[backspace=4cm, topspace=2cm, height=middle]
\starttext
\input{lorem}
\margintext{I have discovered a truly
            marvelous proof ...  but
            this margin is too narrow
            to contain it.}
\input{lorem}
\inmargin{\externalfigure[cow] [width=\marginwidth]}
% The above works.
% The following does not:
\input{lorem}
\inmargin{
\starttikzpicture
  \draw[gray] (-2,0) grid (2,2) ;
  \draw plot [domain=-2:2, samples=50, smooth] (\x,{\x * \x});
\stoptikzpicture
}
\stoptext

-> Undefined control sequence

I tried using \startfigure, \hbox... no success.

Actually the command \startmarginblock ... \stop... described in the ConText reference works with a TikZ picture. But the picture, in the margin, gets near the top of the page. I don't understand the meaning of the options (especially the difference between `location' and `align'). And is it `\setuppagenumbering[alternative=doublesided]'-aware ?
Example:

\usemodule[tikz]
\setuplayout[backspace=4cm, topspace=2cm, height=middle]
\setuppagenumbering[alternative=doublesided]
\starttext
\input{lorem}
\inmargin{\externalfigure[cow] [width=\marginwidth]}
\pagebreak
\input{lorem}
\input{lorem}

\blank
We would like the picture to go the the left of this paragraph.
\setupmarginblocks[location=left,align=inner]
\startmarginblock
\starttikzpicture[scale=0.2]
  \draw[gray] (-2,0) grid (2,2) ;
  \draw plot [domain=-2:2, samples=50, smooth] (\x,{\x * \x});
\stoptikzpicture
\stopmarginblock
\stoptext


Best regards

Does \placefigure[margin]{caption}{... tikzpicture ...} fit your needs?

That generally works, but using LMTX there’s a horizontal shift on left pages (still need to prepare a MWE for that).

Most likely because the argument of \inmargin is scanned upfront and at that time \draw etc are undefined. One option is:

\startbuffer[picture]
\starttikzpicture
...
\stoptikzpicture
\stopbuffer

\inmargin{\getbuffer[picture]}

Another option (but better to do that in tikz module) is:

\let\draw\relax
\let\x\relax

\inmargin{\starttikzpicture ... \stoptikzpicture}

Because the \start ... \stop blocks don't scan the argument.

Here's one for you to ponder:

we have this:

  % \doifelsenothing{#content}\donefalse\donetrue

we could use the slower (maybe even side effects)

  % \doifelsetext{#content}\donetrue\donefalse

but go modern instead:

    \ifparameter#content\donefalse\or\donetrue\else\donefalse\fi

i'll add that last one to lmtx
