Re: inlining pretty-printed XML

Re: inlining pretty-printed XML

[Guy Worthington]

I've looked at the verb-XML module, and verb-ini module, and have 
have seen hints that it may be possible to typeset XML code snippets,
such as   <table>  into the main text.

Is it possible to inline such XML expressions into the main text,
using the same color setup as has been defined in the verb-XML macros?

I'm seem to be using this mailing list as private correspondence, I'll
try to keep my posting down in future.  But..

Following up on my question on how to inline XML code, I vaguely
remember reading that the TeX primitive \par, has no effect in
restricted horizontal mode, (I think that's what it's called, anyways
the horizontal mode that's not paragraph mode).  So on that
assumption, I forced the verbatim pretty printer to operate inside an
\hbox, with the following code:

--------------------------------------------------

%output=pdf
\definetyping [XMLtag] [option=XML]
\setuptyping [XMLtag] [before={\ \hbox\bgroup},
                       after={\egroup\ },
                       palet=colorpretty]
    
\setupcolors[state=start]

\starttext

This is a 
\startXMLtag 
<TABLE/> 
\stopXMLtag
tag inline; and this is a comment 
\startXMLtag
<!-- comment -->
\stopXMLtag

\startXML
<!-- This is displayed XML -->
<TABLE/>
\stopXML    

\stoptext

did you try:

\setupcolors[state=start]

\definetype[typeXML][option=XML,palet=colorpretty]

test \typeXML{<what/>} test

\startXML
<what>
\stopXML

(ps i just found out that the palet is not predefined here, but the 
previous code should work ok)

Another nice one is:

%\setupXMLfile[level=2]
%\showXMLlin[here,there]
%\showXMLwrd[whow]

(ign,lin,wrd,par,txt,nop,emp)

\startbuffer
<here> <there> <whow> oeps </whow> </there> </here>
\stopbuffer

\showXMLbuffer

there is also \showXMLfile

i'll add an

\showXMLtext{<here> <there> <whow> oeps </whow> </there> </here>}
\showXMLtext{<here><there><whow>oeps</whow></there></here>}

this trickery is used in:

texexec --pdf --use=xml-01 somexmlfile [--mode=packed,wide]  : use 
pdftotext afterwards and you'll have a prettier xml file
texexec --pdf --use=xml-02 somexmlfile                       : pretty print 
(recognized xsd, rlg, xml, exa)

The code works, and, as usual, you've upstaged me with a much cleaner
interface.

Hans, you make life hard.  I've been playing around with this, this
afternoon, it's like magic.  But now I've got to rethink how I
format XML to exploit the pretty-printing capability, especially how I
should group elements.

Do you wake up in the morning and think to yourself I'll build a
better version of lgrind?  This I can use immediately.  Thankyou.

And it also comes in colour.

Say that you use relax ng, have the following def's in, say, eximple.rng:

<?xml version="1.0" ?>

<?context-block begin grammar ?>

<grammar xmlns="http://relaxng.org/ns/structure/1.0">

<?context-block end grammar ?>

<?context-block begin framework ?>

<start>
   <choice>
     <ref name="request"/>
     <ref name="reply"/>
   </choice>
</start>

<?context-block end framework ?>

.....

<?context-block begin grammar ?>

</grammar>

<?context-block end grammar ?>

then you can say:

\definefilesynonym [eximple] [eximple.rng]

and later on pick up the components:

\showRNGcomponent[eximple][framework]

saves you some work and make documentation in a separate file easier
