\textrule and Bidi - dev-context

16 Dec 2019


      Hi,
in RTL text direction the middle and bottom alternatives of \textrule 
extend into the right margin.
\setupalign[righttoleft]
\starttext
\textrule[top]{}
\textrule[middle]{}
\textrule[bottom]{}
\stoptext
A fix for this is to use \naturalvpack instead of \vpack.
%%%% pack-mrl.mkiv
\def\pack_textrule_with_text_nop#1%
   {\ifhmode
      \endgraf
    \fi
    \doifelse{\directtextrulesparameter\c!depthcorrection}\v!on
      \pack_textrule_correct_depth_yes
      \pack_textrule_correct_depth_nop
    \nointerlineskip
-  \noindent\vpack % was \dontleavehmode
+  \noindent\naturalvpack % was \dontleavehmode
      {\color[\directtextrulesparameter\c!rulecolor]
         {\hrule
            \s!depth \directtextrulesparameter\c!rulethickness
            \s!height\zeropoint
            \s!width \availablehsize}}}
