interlinespacing

interlinespacing

[Idris S Hamid]

Dear Board,

It's going to take some work to come up with a test file for this
problem (since the font is not publically available), but let me
describe it anyway:

Arabic visually requires larger font sizes than roman, as well as wider
interline spacing, so Arabic insertions in Latin can create lines of
mixed interline spacing. Very strangely, this problem is more apparent
in itemize environments and the like than in regular text. Question: is
there a way to turn off interline spacing completely for my insertions
when necessary. Insertions are defined in terms of \startarabictext
\stoparabictext environments:

\definestartstop
  [arabictext]
  [commands=%
    {\osetarabdirtext % switches to RL mode
    \arabictextfont % switches to Arabic
    \vocalizeinsertdefault} % calls default otp list for vocalization
    ]

Silly me, coming up with an example is the most trivial thing, since only
the size and not the typeface is the relevant issue:

\starttext

Thus, I came to the conclusion that the designer of a new system
must not only be the implementer and first large||scale user;
{\tfb the designer should also write the first user manual}. The
separation of any of these four components would have hurt \TeX\
significantly. If I had not participated fully in all these
activities, literally hundreds of improvements would never have
been made, because I would never have thought of them or perceived
why they were important.

\stoptext

The {\tfb} line has more interlinespacing of course. Is there a way I can
force ConTeXt to reduce the interline spacing of the {\tfb } insert so that
all the lines are even (even if the insertion overlaps the main text)? My
own insertions are in terms of \start\stop environments so presumably the
same solution will apply there. There are some cases where this will look
much nicer.

Thnx in advance
Idris

for something short inline you can use \struttedbox{some text} but 
otherwise the only thing you can do is accept, unless you want things like

\beginshapebox \bfd \dorecurse{100}{(test) }\endshapebox

\reshapebox{\ruledhbox{\struttedbox{\box\shapebox}}} \flushshapebox

which you don't want

this should be a font characteristics (glyph boundingboxes smaller than 
normal.

\long\def\startarabictext#1\stoparabictext
   {{\bfd\processisolatedwords{#1}\struttedbox}}
     ^^ otp switches

\long\def\arabictext#1{\startarabictext#1\stoparabictext}

\dorecurse{10}
   {test test \startarabictext well o well\stoparabictext test }

i have no idea if this works well with arabic

This works beautifully! There is only one (unfortunately major) glitch:

I have defined my inserts to use `<' and `>', but I'm having problems
defining
the above macros in these terms. Compare the first and second paragraphs
in
the following: the first works fine but the second reports a "Runaway
Argument?" How can I fix this? I don't want to activate the angle
brackets
inside of the definition since in some applications I use them for other
things (like in critical editions).

The following test file illustrates the problem.

==========================
\long\def\startarabictext#1\stoparabictext
   {{\bfd\processisolatedwords{#1}\struttedbox}}

\long\def\arabictext#1{\startarabictext#1\stoparabictext}

\catcode`\<=\active
\catcode`\>=\active
\def\startarabictextv{\startarabictext}
\let<=\startarabictextv
\let>=\stoparabictext

\starttext

Thus, I came to the conclusion that the designer of a new system
must not only be the implementer and first
\startarabictext test \stoparabictext
large-scale user; the designer should also write the first user manual.

Thus, I came to the conclusion that the designer of a new system
must not only be the implementer and first
<test>
large-scale user; the designer should also write the first user manual.

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

All the best

you need a delimited def, so

   \catcode`\<=\active \def<#1>{\startarabictext#1\stoparabictext}

or nicer:

   \defineactivecharacter < {\quickanddirtyarabic}

   \def\quickanddirtyarabic#1>{\startarabictext#1\stoparabictext}

Great! Everything will look so much nicer now.

ok, so test it and later we will see how it can end up in a proper environment
