ok, another attempt ... see typo-dir file


It works for my small test file, Idris can check it with a real document.

Thank you very much,

Another problem is that you can’t set a global direction because the 
command is embedded in \setupdirections.

I can understand your concerns.

Another way is to add additional commands which let you set the script 
for all environments (body text + footnotes).



1. Add "global" to the attribute definition (or add another keyword 
which doesn’t add the reset to the local token list but using "global" 
should be enough).


%% attr-ini.mkiv
\def\attr_basics_define_indeed#1[#2][#3]%
   {\ifcsname\??attributecount#2\endcsname\else
  \scratchcounter\clf_defineattribute{#2}{#1}\relax
     %\writestatus\m!system{defining #1 attribute #2 with number 
\number\scratchcounter}%

\expandafter\attributedef\csname\??attributecount#2\endcsname\scratchcounter
  \expandafter\newconstant \csname\??attributeid#2\endcsname
  \csname\??attributeid#2\endcsname\scratchcounter
  % some attributes are always global
  \doifelseinset\s!global{#3}%
{\etoksapp\t_attr_list_global{\csname\??attributecount#2\endcsname\attributeunsetvalue}}%
-  {\etoksapp\t_attr_list_local 
{\csname\??attributecount#2\endcsname\attributeunsetvalue}}%

+  {\doifnotinset\s!none{#3}
+ {\etoksapp\t_attr_list_local 
{\csname\??attributecount#2\endcsname\attributeunsetvalue}}}%

  \doifinset\s!nomath{#3}%
{\etoksapp\t_attr_list_nomath{\csname\??attributecount#2\endcsname\attributeunsetvalue}}%
  % here public means 'visible' so it's not to be confused with 
'public' at the lua end

  \doifinset\s!public{#3}%
{\expandafter\let\csname#2\s!attribute\expandafter\endcsname\csname\??attributeid#2\endcsname}%
    \fi}
%%



2. Create a flag which can be used to prevent the reset of the 
attributes when you use the global-commands. The old \setscript command 
will be a synonym for the local settings while you can use the global 
command when the document contains only one language.


%% scrp-ini.mkiv
\newconditional\c_scripts_reset \settrue\c_scripts_reset

     \ifconditional\c_scripts_reset

Hi Hans,

the \setscript command has the same problem with local attributes as the 
bidi mechanism.


Some of the following attributes in scrp-ini.mkiv have to be global:


\definesystemattribute[scriptinjection][public]
\definesystemattribute[scriptsplitting][public]
\definesystemattribute[scriptstatus]   [public]


I know "scriptinjection" has to be global to have linebreaks in 
footnotes (and margin notes) for chinese and japanese.


I guess "scriptsplitting" has to be global too because it is used for thai.
it needs a bit of thinking (even bidi) ... it compares to global and 
local bodyfonts


what if a page break occurs in the middle of japanese local text while 
the global script is chinese
