line numbering interupted

line numbering interupted

[Matthew Huggett]

Hi:

I have a document with line-numbering.  When I use one of my own commands---
for example, \Red{Some Words in Red}--- the line-numbering stops working.
The line-numbering works fine without these homemade commands.  Any ideas as
to why this might be?

Best wishes,

Matthew Huggett

This is a limitation of tex: one cannot disassemble boxes with marks (which 
we used to keep track of colors.

So, the solution is: \setupcolors[state=local] which is ok as long as color 
does not cross pages.

A better way is (in cont-new.tex):

\newevery \everyshapebox \relax

\def\beginofshapebox%
   {\setbox\oldshapebox\normalvbox
      \bgroup
      \reshapingboxtrue
      \the\everyshapebox
      \normalhbox to \shapesignal{\strut\hss}%
      \prevdepth\dp\strutbox}

\appendtoks \localcolortrue \to \everyshapebox

Now, the latest version has a problem with spacing (introduced when 
extending the number placement), in cont-new there should be (only in 
latest version!):

\def\dodoschrijfregelnummer%
   {% beware of em's, the font is already switched !
    \setbox\scratchbox\hbox
      {\setbox0\hbox{\@@rncommando{\regelweergave}}\vsmashbox0%
       \ifcase\linenumberlocation
         \rlap{\hbox to \@@rnbreedte{\box0\hss}}% was \llap, nog testen !!
       \or
        %\llap{\hbox to \@@rnbreedte{\hss\box0\hskip\linkermargeafstand}}%
         \inleftmargin
           {\forgetall
            \doifelse\@@rnbreedte\v!marge
              {\hsize\linkermargebreedte}{\hsize\@@rnbreedte}%
            \alignedline\@@rnuitlijnen\v!rechts{\box0\hskip\@@rnafstand}}%
       \else
         \inrightmargin
           {\forgetall
            \doifelse\@@rnbreedte\v!marge
              {\hsize\rechtermargebreedte}{\hsize\@@rnbreedte}%
            \alignedline\@@rnuitlijnen\v!links{\hskip\@@rnafstand\box0}}%
       \fi}%
    \vsmashbox\scratchbox
    \box\scratchbox}
