Separation of delimited text symbol

Separation of delimited text symbol

[Marco Patzer]

Hi,

this issue was raised on stackexchange¹. When setting up a delimited
text, a line break is allowed between the character and the
following text, which is always undesired (maybe I lack imagination
where this might be intended). Example:

\setuplayout [width=10cm]

\definedelimitedtext
  [quotation]
  %% [left={\symbol[leftquotation]}] %% works
  [left=“]                           %% separates symbol from the text

\starttext
  När jag som liten uppgett att teckningen föreställer \quotation{Tomtarnas eld
  i skogen} kanske det inte alls var menat som en optisk liknelse av denna
  händelse.
\stoptext

Setting the delimiter as part of the language setting does not cause
the symbol to be separated.

If there's no use-case for this behaviour, can it be fixed?

The following change in typo-del.mkiv prevents the line break.

\def\typo_delimited_handle_left#1%
  {\begingroup
   \setbox\scratchbox\hbox{\delimitedtextparameter#1}%
   \ifdim\wd\scratchbox>\zeropoint
     \ifdim\lastkern=\d_typo_delimited_signal
       \unkern
       \hskip\hspaceamount\currentlanguage{interquotation}%
     \else\ifdim\lastskip=\d_typo_delimited_signal
       \unskip
       \hskip\hspaceamount\currentlanguage{interquotation}%
     \fi\fi
     \strut % new, needed below
     \ifhmode % else funny pagebeaks
       \penalty\plustenthousand
       \hskip\zeropoint % == \prewordbreak
     \fi
     \strut % new, needed below
     \delimitedtextparameter#1% unhbox\scratchbox
+    \penalty\plustenthousand
     \hskip\d_typo_delimited_signal % +- \prewordbreak
   \fi
   \endgroup}

Thanks Wolfgang for the code and thanks to Hans for incorporating
this into the core.
