In-line syntax highlighting for type

In-line syntax highlighting for type

[Aditya Mahajan]

Hi,

How can I define a command that is the inline version of \startTEX ... 
\stopTEX. (I need to show inline commands in color). There had been a 
discussion on this in the past, and Taco had suggested a solution

http://archive.contextgarden.net/thread/20050907.093522.baf795f5.en.html

which is also posted on the wiki.


http://wiki.contextgarden.net/Verbatim_text#In-line_text

However, due to the recent changes in verbatim code, that solution no 
longer works. Can anyone suggest how to fix it?

Thanks,
Aditya

\setupcolors[state=start]

\setuptype[option=TEX]

\definetype[typeTEX][option=tex]

\starttext

\type+\type{\type is a wonderful macro}+, isn't it?

\typeTEX+\typeTEX{\typeTEX is a wonderful macro}+, isn't it?

\stoptext

Thanks, that looks easy :-)

However, there seems to be a bug, sometimes the color spills across 
the type boundary.

\setupcolors[state=start]

\setuptype[option=TEX]

\definetype[typeTEX][option=tex]

\starttext
The options \type+before=\startsolutionbackground+ and
\type+after=\stopsolutionbackground+ take care of putting a frame, 
which can

{\black
The options \typeTEX+before=\startsolutionbackground+ and
\typeTEX+after=\stopsolutionbackground+ take care of putting a frame, 
which can
}

\stoptext

Is is possible that everything written with \tex{command} is also 
printed in color? I do not want to change \tex{command} to 
\type{\command} since \tex is more robust (No catcode trickery and 
stuff).

I wanted to warn you about that, but you were faster. A workaround is
to create an additional space: so to \type{\commands }like that.

There are many bugs in \type-ing code, but the code is rather complex
... even Taco complaind about complexity.

Hopefully lua will be able to do the task better ;)

actually, the mkiv code does it completely different already, but that's 
on my machine -)

hm, that many? well, keep in mind that everything that involves catcode 
changes combined with arguments will be messy;

also, much of this code evolved when mem and speed were issues, and of 
course there was this \type+crap+ kind of syntax to deal with as well

the problem is that we cannot mess around too much with egroup because otherwise we get into problems with alignments (which have their own idea about these things

I understand that this is one of the more tricky things in TeX. Right 
now, Mojca's workaround of adding a space after the comand works most 
of the time. If there is a punctuations after the type+...+ one does 
not want a space between the type and the punctuation. \unskip and 
friends make the output look alright, but with a horrible looking 
source.

I hope that lua will make doing these things a bit easier.

in that case the whole pretty printing is done in lua ; in tex we have to use aftergroup stuff and the problem is that info is lost on the way (ok, there is a solution, but it involves messy macros because we want to use all that stuff nested as well)
