indentnext=auto

indentnext=auto

Dear gang,

For export we have to tag paragraphs. After block quotes, itemizations,  
etc, the context determines whether the first line of the next paragraph  
should be indented, so we use the indentnext=auto mechanism. But with  
\start|stopparagraph it doesn't seem to work: See attached.

====================
\setupindenting[big,yes]
% Do not indent the first line of a block quote
\setupdelimitedtext[blockquote][before={\blank[medium]  
\setupindenting[no]},after={\blank[medium]}]
% Do not indent the first line after a block quote
\setupdelimitedtext[blockquote][indentnext=auto]

\starttext
\startparagraph
\input ward
\stopparagraph

\startblockquote
\input ward
\stopblockquote

\startparagraph
\input ward
\stopparagraph

\startblockquote
\input ward
\stopblockquote
\startparagraph
\input ward
\stopparagraph
\stoptext
====================

 From what I understand, if [indentnext=auto] is activated then a blank  
line after the environment should activate indenting; no blank line after  
the environment should impede indenting.

In this example, we get no indentation either way. Am I missing something,  
or is it a bug?

By the way, something like

\setupdelimitedtext[blockquote][indentnext=yes]

\startparagraph[indenting=no]
\input ward
\stopparagraph

would be a nice feature. Any chance?

Best wishes
Idris

\setupdelimitedtext
  [blockquote]
  [spacebefore=medium,
   spaceafter=medium,
   indenting=no]

It’s bug in the delimited text mechanism (typo-del.mkvi), a \aftergroup is missing before \dorechecknextindentation.

\def\typo_delimited_stop_par
  {\removeunwantedspaces
   \removelastskip
   \rightdelimitedtextmark
   \carryoverpar\endgroup % new per 2013-01-21 ... please left floats
   \popmacro\checkindentation
   \typo_delimited_stop_par_indeed
   \delimitedtextparameter\c!after
   \edef\p_delimited_spaceafter{\delimitedtextparameter\c!spaceafter}%
   \ifx\p_delimited_spaceafter\empty \else
     \blank[\p_delimited_spaceafter]%
   \fi
   \useindentnextparameter\delimitedtextparameter
-  \dorechecknextindentation}% AM: This was missing!
+  \aftergroup\dorechecknextindentation}% AM: This was missing!

\startsetups[paragraph:noindent]
	\setupindenting[no]
\stopsetups

\defineparagraph[noindent][setups=paragraph:noindent]

\setupindenting[yes,big]

\starttext

\startparagraph
\input ward
\stopparagraph

\startparagraph[noindent]
\input ward
\stopparagraph

\startparagraph
\input ward
\stopparagraph

\stoptext

Wow, so a bug indeed... I hope Hans is reading this -)

Wonderful, this is so much better than an explicit \noindentation. I  
really need to spend some time to learn the power of setups! Thanks a  
million, Wolfgang, and

The opposite scenario doesn't work, viz.

==========
% setup paragraph indents
\startsetups[paragraph:indent]
	\setupindenting[big,yes]
\stopsetups
\defineparagraph[indent][setups=paragraph:indent]
==========

But this appears to work:

==========
% setup paragraph indents
\startsetups[paragraph:indent]
	\indentation
\stopsetups
\defineparagraph[indent][setups=paragraph:indent]
==========

So there is significant difference in the \setupindenting[yes] case. For  
consistency we may as well go with

=================
\startsetups[paragraph:indent]
	\indentation
\stopsetups
\defineparagraph[indent][setups=paragraph:indent]
\startsetups[paragraph:noindent]
	\noindentation
\stopsetups
\defineparagraph[noindent][setups=paragraph:noindent]
=================

This entire approach is better and wiser than indentnext=auto anyway.  
Thanks again, Wolfgang, and

Best wishes
