Use headcommand in \definedescription together with \definehighlight
Hi, I was in the process to convert an itemize part to a description and wanted to simplify the code in the same move. I discovered headcommand for that, but struggled to set the text in an highlight _and_ make a colon at the end. Do you know, if this is possible? Here is a MWE: ``` \definehighlight[hl][style={\m{>}\,\switchtobodyfont[tt]}] \definedescription[category][ alternative=top, headstyle=bold, width=broad, ] \definedescription[desc][ width=broad, distance={\widthofstring{~}}, headcommand={\groupedcommand{\hl}{:}}, % headcommand={\groupedcommand{}{:}}, % this compiles but the highlight is lost % headcommand={\groupedcommand{\starthl}{\stophl :}}, % this does not compile headstyle=, before={\startpacked}, after={\stoppacked}, alternative=hanging, ] \starttext This is a \hl{highlight}. Some listings \startcategory{Itemize} \startitemize[packed] \item \hl{first}: one \item \hl{second}: two \stopitemize \stopcategory Now the same as desc: \startcategory{Desc} \startdesc{first} one \stopdesc \startdesc{second} two \stopdesc \stopcategory \stoptext ``` The itemize looks like it should look (except of the dots). Best, Gerion

Not sure what exactly you want, but how about: \definehighlight[hl][style={\m{>}\,\switchtobodyfont[tt]}] % This is the wrong way to define such a command as '>' is not part of the style. I have left this definition just for comparison with the soln below. \definedescription[category][ alternative=top, headstyle=bold, width=broad, ] \definedescription[desc][ width=fit, distance={\widthofstring{~}}, headcommand={\groupedcommand{>\,}{:}}, headstyle=\tt, before={\startpacked}, after={\stoppacked}, alternative=hanging, ] \starttext This is a \hl{highlight}.

Is there a better way to define a highlight that sets a style (color, font) _and_ a prefix (symbol)? Another way, I know of, would be just a plain def, something like \def{\hl}{\groupedcommand{>\,\switchtobodyfont[tt]}{}}, but actually I want to define a highlight (just with an additional prefix).
\definedescription[category][ alternative=top, headstyle=bold, width=broad, ]
\definedescription[desc][ width=fit, distance={\widthofstring{~}}, headcommand={\groupedcommand{>\,}{:}},
Hmm, this works, but duplicates the above definition. If I don't want to use > as prefix but ›, I need to replace it in two places.
headstyle=\tt, before={\startpacked}, after={\stoppacked}, alternative=hanging, ]

1. ConTeXt already uses \hl as name for a existing command. 2. Use \definestartstop: \definestartstop [gerion] [style=mono,left={›\thinspace}] \starttext text \gerion{text} \stoptext
\definedescription[category][ alternative=top, headstyle=bold, width=broad, ]
\definedescription[desc][ width=fit, distance={\widthofstring{~}},

2. Use \definestartstop:
\definestartstop [gerion] [style=mono,left={›\thinspace}]
\starttext

\gerion{text}

This seems to be much better but does not lead to the wanted result. The full example now is: ``` \definestartstop[myhl][style=mono,left={›\thinspace}] \definedescription[categorie][ alternative=top, headstyle=bold, width=broad, ] \definedescription[desc][ width=broad, distance=\spaceamount, headcommand={\groupedcommand{\startmyhl}{\stopmyhl :}}, headstyle=, before={\startpacked}, after={\stoppacked}, alternative=hanging ] \starttext This is a \myhl{highlight}. Some listings \startcategorie{Itemize} \startitemize[packed] \item \myhl{first}: one \item \myhl{second}: two \stopitemize \stopcategorie Now the same as desc: \startcategorie{Desc} \startdesc{first} one \stopdesc \startdesc{second} two \stopdesc \stopcategorie \stoptext ``` This adopts the correct style in \startdesc \stopdesc and sets the colon but omits the › (the left part).

\definestartstop [gerion] [style=mono,left={›\thinspace}]

You can do the following in the next version. 1. Add "arguments=yes" to \definestartstop to enable the optional argument for the new command. 2. Use the new commands with the "headcommand" key and apply ":" as right delimiter for the content of \Highlight. \definestartstop [Highlight] [arguments=yes, style=mono, left={›\thinspace}] \definedescription [description] [ width=broad, distance=\spaceamount, headcommand=\Highlight[right=:], alternative=hanging] \starttext This is a \Highlight{highlight}. \startdescription[title={Lorem ipsum}] \samplefile{lorem} \stopdescription \stoptext Wolfgang

Thanks, that will work. Do you know, why the groupedcommand solution does not work? Gerion

The command and the environment which are created by \definestartstop can't be interchanged when you use the before/after and left/right keys. %%%% begin example \usemodule[visual] \definestartstop [Example] [before={\par\leftaligned{\tttf [before]}\par}, after={\par\leftaligned{\tttf [after]}\par}, left={{\tttf [left]}}, right={{\tttf [right]}}] \starttext \fakewords{10}{20} \startExample \fakewords{10}{20} \stopExample \fakewords{10}{20} \blank \fakewords{3}{5} \Example{\fakewords{3}{5}} \fakewords{3}{5} \stoptext %%%% end example Wolfgang

Ok, thanks for the explanation (I have added the example to the wiki). Gerion
