Re: [NTG-context] register: spurious space & one more entry level ask

19 Sep 2007

      Jupiiiii!

Both patches (space & 4-level entry) work well as I can test them till 
now. I will do some testing on a real and big document in a near future.

Do you intend to incorporate both patches to the distribution?

Thank you Hans for extremely quick solutions

Dear ConTeXters,
there are 3 topics dealing with register (index):
1. [Spurious space] There are entries like
      \registerpage{index}{,}{5}{2--1-1-0-1-0-0-0--1}{2}
    in a *.tuo file. Since the definition (core-reg.tex)
      \def\dosetpageregisterpage#1#2#3#4#5#6%
        {\doifreglevelelse[#5]%
          {\dodosetpageregisterpage{#1}{#2}{#3}{#4}{#5}{#6}}%
          {}}
    there will be a spurious space between page number like
      Entry 23 , 67
    instead of
      Entry 23, 67
Solution:
      \def\dosetpageregisterpage#1#2#3#4#5#6%
        {\doifreglevelelse[#5]%
          {\dodosetpageregisterpage{#1}{#2}{#3}{#4}{#5}{#6}}%
          {}\ignorespaces}
interesting that no one noticed this before ... in core-uti.tex pushing 
the line ending was messed up when changing to catcode tables (well, 
pseudo ones in mkii)
\long\def\doutilities#1#2#3#4#5% % introduceren in utility file
  {\resetutilities
   % more than one utility thing can be handled in one pass,
   % for instance lists, so we process ##1 as list
   \def\douticommand##1{\csname\s!set##1\endcsname}%
   \processcommacommand[#1]\douticommand
   \begingroup
   \def\currentutilityfilename{#2}%
   \notesenabledfalse
   \doinpututilitiestrue
   \global\utilitydonefalse
   \pushcatcodetable
   \setcatcodetable\ctxcatcodes
   \pushendofline % <<<<<<<<<<<<<<<<<<<<<<<<<
   \ifunprotectutilities % nog nodig ?
     \unprotect
   \fi
...
2. [feature request] Current register implementation enable upto three 
entry level (\index{level 1+level 2+level 3}). My custommer require 4 
levels. Please could the entry number be extended?
not trivial, since we then need to adapt texutil too + a bunch of 
macros; adapting mkiv may be easier
...
3. [not important, just for info] Formating of the register entries is 
not much user friendly. See \hangindent1em in a following definition:
\def\dosetpageregisterentrya#1#2%
     {\flushseenregisterpage
      \edef\currententrylevel{1}%
      \global\let\c!entryb\relax
      \global\let\c!entryc\relax
      \gdef\c!entrya
        {\iffirstregisterentry\else\endgraf\fi % new
         \global\firstregisterpagetrue
         \hangindent1em\noindent\c!entryreference
         \dohandlepageregisterentry{#1}{#2}%
         \global\firstregisterentryfalse
         \global\firstsubentrytrue
         \global\firstsubsubentrytrue}}
So, when one want the change formating he has to redefine this 
definition. It is against a ConTeXt spirit.
some day there will be a better interface (probably only in mkiv)
