no indent after blank

no indent after blank

[Henning Hraban Ramm]

(latest beta MkIV)

With
\setupindenting[yes, medium]
there shouldn't be an indent after a \blank IMO.

How can I suppress it?

\setupindenting[yes,medium]
\starttext
\input knuth
\blank
\noindentation\input ward
\stoptext

or you use my fancybreak [1] module:

\usemodule[fancybreak]
\setupindenting[yes,medium]
\setupfancybreak[indentnext=no]
\starttext
\input knuth
\fancybreak
\input ward
\stoptext

Yes, I tried that. I should have asked "how can I suppress it  
*generally*".
Like in
\def\Gap{\blank[big]\noindent}

Great, works like expected. Thank you!
(I'll probably need fancy breaks anyway...)

I'll have a more detailed look at it later (remind me that we need to 
formalize this \???? namespace for modules issue; we might need \??? for 
the core soon as we run out of \??'s).

I wonder what the side effects of \everyvbox are as the next box content 
can have vboxes itself (ok, you can do an everyvbox\emptytoks inside the 
\everyvbox); maybe \dowithnextboxcontent can be used here

\def\dodofancybreak
   {\begingroup
    \everyvbox
      {\setupalign[\fancybreakparameter\c!align]%
       \doifmode\s!mkiv{\dosetfancybreakattributes\c!style\c!color}}%
    \dowithnextbox
      {\blank[\fancybreakparameter\c!spacebefore]%
       \flushnextbox
       \blank[\fancybreakparameter\c!spaceafter]%
       \checknextindentation[\fancybreakparameter\c!indentnext]%
       \dorechecknextindentation
       \endgroup}
      \normalvbox}

so:

    \dowithnextboxcontent
      {\setupalign[\fancybreakparameter\c!align]%
       \doifmode\s!mkiv{\dosetfancybreakattributes\c!style\c!color}}%
      {\blank[\fancybreakparameter\c!spacebefore]%
       \flushnextbox

Another convention could be

\doifmode\s!mkiv{\let\dosetfancybreakattributes\gobbletwoarguments}

so that you then get (less testing):

    \dowithnextboxcontent
      {\setupalign[\fancybreakparameter\c!align]%
       \dosetfancybreakattributes\c!style\c!color}%
      {\blank[\fancybreakparameter\c!spacebefore]%
       \flushnextbox

As you write nice and clean modules that are perfect examples for 
others, we should take some time at the context conference and see if we 
can derive some 'module writing conventions'.

I wonder if I should finaly make a definer for \fancybreakparameter like 
cases. I had one once but it looked quite horrible and there are subtle 
differences between all cases but I'll give it a try some day soon.

Hans

I have started use \??whatever?? to avoid clashing with Wolfgang :-)

Wolfgang taught me how to use them and now I use
(http://github.com/adityam/filter/blob/master/t-filter.tex)

\def\externalfilterparameter 
#1{\csname\docheckparentparameter{\??externalfilter??\currentexternalfilter}#1\endcsname}

\def\docheckparentparameter 
#1#2{\ifcsname#1#2\endcsname#1#2\else\expandafter\redocheckparentparameter\csname#1\s!parent\endcsname#2\fi}

\def\redocheckparentparameter#1#2{\ifx#1\relax\s!empty\else\docheckparentparameter#1#2\fi}

I am pretty sure this does not cover all the situations that arise in the 
core.

I changed it now to \dowithnextbox and it works as well, the main 
purpose of the macro is to insert
a symbol between paragraphs but it's true you can't know how other 
people misuse the function.

Done although it has to be \doifmode\v!mkii ;)

I want to use this module myself to present how to include macros to 
document a modules source (%M, %D etc.).

You mean \installparameterhandler in str-def.mkiv?

The macro is interesting but three arguments are enough because 'framed' 
part is always the same in the parameter commands.

indeed, but i need to think about some variants as well, as there are 
differences in parent resolving (or something like that) ... eventually 
we will have this parent chain in all comands i guess (less hash space 
wasted but a bit slower but normally that's not the bottleneck)

looks interesting, can't test it today but there a few things which are 
not right

\unexpanded\def\doinstallparameterhandler#1#2#3#4#5#6#7#8#9% \??aa 
{whatever} \current..
   {\def#3##1{\csname#6{#1#2}{##1}\endcsname}%
    \def#4##1{#7{#1#2}{##1}}%
-  \def#5##1##2{\csname#6{#1##2}{##1}\endcsname}%
+  \def#5##1##2{\csname#6{#1##1}{##2}\endcsname}%
    
\def#6##1##2{\ifcsname##1##2\endcsname##1##2\else\expandafter#8\csname##1\s!parent\endcsname{##2}\fi}%
    \def#7##1##2{\ifcsname##1##2\endcsname   
##1\else\expandafter#9\csname##1\s!parent\endcsname{##2}\fi}%
    \def#8##1##2{\ifx##1\relax\s!empty\else#6{##1}{##2}\fi}%
    \def#9##1##2{\ifx##1\relax        \else#7{##1}{##2}\fi}}

For \named...parameter it's better to use the first argument the name of 
the environment
and the second for the key, e.g. \namedwhateverparameter{command}{width}


Here

\unexpanded\def\doinstallcommandhandler#1#2#3#4#5#6#7#8%
   {...
    \def#5[##1][##2]%
      {\edef#4{##1}%
       \ifsecondargument
         \getparameters[#1#4][\s!parent=#1##2]%
       \else
         \getparameters[#1#4][\s!parent=#3]%
       \fi
    ...}

you forgot the comma before '##2'.

Ok, fixed. I also need to add \detokenized...parameter an maybe more. 
But at least we have something to discuss (apart from \???? namespaces).

Can you also extend the defintion of the \setup... command to allow 
environment lists, e.g.

\setup...[one,two][..=..]
