%D just use fontid
%D \macros
%D {showbodyfont}
%D
%D One can call for a rather simple overview of a bodyfont and the relations between
%D its alternative fonts.
%D
%D \showsetup{showbodyfont}
%D
%D The current bodyfont (here we omitted the argument) looks like:
%D
%D \showbodyfont
%D
%D The implementation is rather straightforward in using \type {\halign}.
\fetchmodulecommand \showbodyfont \f!font_run
%D \macros
%D {showfontstrip, showminimalbaseline}
%D
%D The next command can come in handy when combining different fonts into a
%D collection (typeface) and determining optimal baseline distances.
%D
%D \showfontstrip \blank \showminimalbaseline
\fetchmodulecommand \showfontstrip \f!font_run
\fetchmodulecommand \showminimalbaseline \f!font_run
%D \macros
%D {showkerning}
%D
%D A goody is:
%D
%D \showkerning{Can you guess what kerning is?}
\fetchmodulecommand \showkerning \f!font_run
%D \macros
%D {showbodyfontenvironment,showfont,showfontstyle,showligatures}
%D
%D The current bodyfontenvironment is:
%D
%D \showbodyfontenvironment
%D
%D This overview is generated using:
%D
%D \showsetup{showbodyfontenvironment}
\fetchmodulecommand \showbodyfontenvironment \f!font_run
%D The following command generates a fontmap:
%D
%D \startbuffer
%D \showfont[SansBold at 12pt]
%D \stopbuffer
%D
%D \typebuffer
%D \getbuffer
\fetchmodulecommand \showfont \f!font_run
\fetchmodulecommand \showfontstyle \f!font_run
\fetchmodulecommand \showligature \f!font_run
\fetchmodulecommand \showligatures \f!font_run
\fetchmodulecommand \showcharratio \f!font_run
\fetchmodulecommand \showfontparameters \f!font_run
\permanent\protected\def\showchardata#1{\ctxcommand{showchardata("#1")}} % todo: direct implementor
\permanent\protected\def\showfontdata {\ctxcommand{showfontparameters()}} % todo: direct implementor
%D \macros
%D {doiffontpresentelse}
%D
%D \starttyping
%D \doiffontpresentelse{texnansi-lmr10}{YES}{NO}
%D \doiffontpresentelse{adam-lindsay-modern-serif}{YES}{NO}
%D \stoptyping

%D The otf tracer code is now moved. If the individual commands are needed
%D one can just load the module.
