[dev-context] \uncompressedlist macro

12 Nov 2005

      Hi Hans,

Can you perhaps put this macro in the core somewhere?
It is the inverse of \compresslist.

Cheers, Taco

(In the collector, this is item #21)

% -----------------------------------------------------------
%D \macros {uncompresslist}
%D
%D When given a list like \type{1,4-7,9} as argument, this macro
%D will store the expanded commalist in \type{\uncompressedlist}.
%D
%D \startbuffer
%D \def\MojcaHasToDoTheTasks[#1]#2%
%D   {{\uncompresslist[#1]%
%D     \def\processitem##1{I have to do ##1 #2\par}%
%D     \processcommacommand[\uncompressedlist]\processitem}}
%D
%D \MojcaHasToDoTheTasks[1-4,7,9-11]{until tomorrow}
%D \stopbuffer
%D
%D Here is an example of how to use \type{\uncompresslist}:
%D \typebuffer
%D
%D The output of this is:
%D
%D \getbuffer

\def\uncompresslist[#1]%
   {\let\uncompressedlist\empty
    \def\docompressedlistitem##1-##2-%
      {\@EA\dorecurse\@EA
        {\the\numexpr 1+##2-##1\relax}%
        {\@EA\appendtocommalist\@EA
          {\the\numexpr ##1-1+####1\relax}\uncompressedlist }}%
    \def\douncompresslist##1%
      {\doifinstringelse{-}{##1}
        {\docompressedlistitem##1-}
        {\appendtocommalist{##1}\uncompressedlist}}%
    \processcommalist[#1]\douncompresslist }
