Linespacing in startstop

Linespacing in startstop

[Idris S Hamid]

The following two ways of defining the linespacing inside a startstop 
environment don't seem to work:

\definestartstop
  [test]
  [commands=%
     \switchtobodyfont[foo,10pt]  % may comment this as well
     %{\baselineskip 36pt}]
     {\setupinterlinespace[line=36pt]}]

Here is a test:

\starttest
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
\stoptest

The spacing does not change as desired.

Please advise!

Best wishes

This is a version that works (but can be improved):

\definestartstop
   [test]
   [commands={\switchtobodyfont[18pt]% may comment this as well
      \setupinterlinespace[line=36pt]},after={\blank[big]}]

\starttext
Here is a test:

\starttest
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test

\stoptest

and a few lines after the test is over and has proved to work. 
The point is the paragraph (aka newline) {\bf inside} the {\tt 
startstop} and the argument to {\tt commands} being grouped with 
  braces.

The \tex{blank} is for making the space at the bottom the same 
as the one above -- there must be a better way \dots
\stoptext

Strange, it does not work at all here (there is still no proper interlineline 
spacing), and the <,after=> gets echoed in the output. This is under the 
default format file with a recent ConTeXt. Thanks for trying though. Here is 
the definition again:

\definestartstop
   [test]
   [commands={\switchtobodyfont[18pt]% may comment this as well
      \setupinterlinespace[line=36pt]}]%,after={\blank[big]}}]

There is (besides the commenting out) an unmatched brace. 
\switobodyfont and \setupinterlinespace have to grouped by 
braces (to ty them to commands) and \blank[big] has to be 
surrounded by braces. The curly braces [] are from commands to 
the end of \blank[big].

And have you honoured the blank line _before_ \stoptest?  This 
is important cause TeX switches linespacing at the end of a 
paragraph.  (Normally \setupinterlinespace forces this within 
the paragraph -- but it seems to fail here)

OK, here's another try:
==============================
 \definestartstop [test] [commands=%{\switchtobodyfont[18pt]}
   {\setupinterlinespace[line=36pt]}]%,after={\blank[big]}}]

\starttext

\starttest
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test

This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
\stoptest

\stoptext
================================

Now I get interline spacing, but _only_ in the first paragraph!  Uncommenting
, after={\blank[big]}]
makes no difference of course.

How can I get it in every paragraph (but _only_ within the environment)?

the point is that just before the \stoptest the paragraph does not
end. The \stoptest restores the values (esp. the \baselineskip that
you have changed) to their original settings. This is definitely not
what you want. The paragraph needs to be ended before the reset
applys. TeX uses some parameters (including baselineskip) for a
paragraph when it is completed. So you can change these settings on
and on and only the last will be used. (This is the case here)

So you can do the following things:

leave a blank line between your last row and \stoptest or say
....\par\stoptest (which is the same). Or you might post this as a bug
to the bugzilla site and let Hans fix it. But this is probably a
feature and not a bug.

\definestartstop
   [test]
   [before={\setupinterlinespace[1.5]},
    after=\endgraf]

will work ok, you need to end a par within the group, since tex uses par 
specific spacing settings that count at th eend of a paragraph (which in 
your case is ended *after* the start/stop group ends

compare:

\bgroup \baselineskip 1cm \input tufte \egroup \par

\bgroup \baselineskip 1cm \input tufte \par \egroup

[same for left/rightskip and indentation]

it actually is a feature since start-stop material may be inline in which 
case we don't want a par; therefore, \endgraf or \paragraph is needed

Now we have another problem, the paragraph after \stoptest does not revert 
back to the old interlinespace:

\definestartstop
   [test]
   [before={\setupinterlinespace[2]},
    after=\endgraf]

\starttext

\starttest
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test

This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
\stoptest

This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test
This is a test This is a test This is a test This is a test

I tried

\bgroup \baselineskip 1cm \input tufte \egroup \par

\input tufte

\bgroup \baselineskip 1cm \input tufte \par \egroup

\input tufte

The  line
\bgroup \baselineskip 1cm \input tufte \par \egroup
does not have the same problem as the start/stoptest environment.

ah, you got me by surprise !

before={\start\setupinterlinespace[2]},
after={\endgraf\stop},

since before and after are expanded outside the embeded group (this is 
because otherwise font switches spoil spacing around sucn constructs
