Hello all.
It seems that \usetikzlibrary is sometimes read, sometimes not, and I don't understand why.
Rationale:
I would like, using one file, to use it to produce a picture, as with LaTeX's Standalone class,
but to be able to include it in a calling document as well, for better management of fonts, etc.
Thus this is most convenient. I have everything in the main document and I can quickly reuse any figure elsewhere.
What I did:
I use \readfile in a main ConTeXt file document.tex to include the file included.tex .
The file included.tex should contain *just* the TikZ picture and what is needed to compile it "standalone".
The issue:
It seems I can call the file with the TikZ picture description multiple times, with \readfile,
from within the very same \placefigure.
However, if I call it by using two successive \placefigure commands,
the \usetikzlibrary[blabla] in the included file doesn't seem to be recognised.
E.g. with the provided example below, the key "right angle" is not understood, as if \usetikzlibrary[angles] was not there.
One workaround would be to use \usetikzlibrary[allTheLibrariesISupposeMightEverBeNeeded]
in the calling file. But I don't like it. I would rather have only the TikZ libraries relevant to some picture included in the corresponding file.
I'm quite startled by the fact that :
> \placefigure[here][]{This is a figure}{
> \readfile{included}{}{File not found.}
> \readfile{included}{}{File not found.}
> }
compiles but
> \placefigure[here][]{This is a figure}{
> \readfile{included}{}{File not found.}
> }
> \placefigure[here][]{This is a figure}{
> \readfile{included}{}{File not found.}
> }
does not.
All the best!
Example:
%%%% Begin document.tex
\usemodule[tikz]
\starttext
\usetikzlibrary[angles] % Doesn't compile if this is commented out.
%\placefigure[here][]{This is a figure}{
% \readfile{included}{}{File not found.}
% \readfile{included}{}{File not found.}
%}
\placefigure[here][]{This is a figure}{
\ReadFile{included}{}
}
\placefigure[here][]{This is a figure}{
\ReadFile{included}{}
}
\stoptext
%%%% End document.tex
%%%% Begin included.tex
\usemodule[tikz]
\usetikzlibrary[angles]
%\doifnotmode{*text,*bodypart}{ \startTEXpage[fit] }
\doifnotmode{*text,*bodypart}{ \startTEXpage[fit] \usemodule[tikz] \usetikzlibrary[angles] }
\hbox{\starttikzpicture[]
\draw[]
(0,0) coordinate (A) node[left] {$A$}
-- (4,0) coordinate (B) node[right] {$B$}
-- (0,3) coordinate (C) node[left] {$C$}
-- cycle
pic [draw, angle radius=0.5cm] {right angle = B--A--C} ;
\stoptikzpicture}
\doifnotmode{*text,*bodypart}{ \stopTEXpage }
%%%% End included.tex
