Title-page overlay

Title-page overlay

[Nikolai Weibull]

I would like to put a rather large and complicated regular expression
into the title-page of a document I'm writing.  So far, I haven't had
much luck defining an overlay that uses \starttyping ... \stoptyping.

Basically, what I figured I should do was to write

\defineoverlay
  [TitleGraphic]
  [{
\starttyping
...
\stoptyping
}]

and then

\setupbackgrounds[page][background=TitleGraphic]

But that doesn't work:

! Argument of \copyverbatimline has an extra }.

Have any suggestions on what I might try?  Basically, what I want is a
background with some arbitrary text, more or less like the pdfTeX user
manual document does it [1],

Hi Nikolai,

May be you should try a buffer to put the typing in. In the overlay you 
can call the buffer with \typebuffer[...]

\startbuffer[title]
...
\stopbuffer

\defineoverlay
  [TitleGraphic]
  [{\startcolor[titlegraphic]\typebuffer[title]\stopcolor}]

\setupbackgrounds[page][background=TitleGraphic]

The problem with that is that everything winds up on one line for some
reason,

Hello Nicolai,

put your \typebuffer stuff in \framed[align=lohi]

you can use width=\overlaywidth and height=\overlayheight if you need.

(or.... post a complete but minimal example)

k, please.

That was a very good suggestion, thank you.  It worked out fine.  This
is what I do now:

\defineoverlay
  [TitleGraphic]
    [{\framed
        [align=middle,width=\overlaywidth,height=\overlayheight,top=\vss,bottom=\vss,foregroundcolor=titlegraphic]
        {\typebuffer[titlebackground]}}]

Thanks,
        nikolai

a good reason: it's a hbox, so you need ...[\vbox{...}]...

alternative regexp title page (nice example for wiki)

% \startbuffer[title]
% /(.*?)testexpr/io
% /t(.*?)estexpr/io
% /te(.*?)stexpr/io
% /tes(.*?)texpr/io
% /test(.*?)expr/io
% /teste(.*?)xpr/io
% /testex(.*?)pr/io
% /testexp(.*?)r/io
% /testexpr(.*?)/io
% \stopbuffer

\definetype[ytyp][color=yellow]

\startbuffer[title]
\type{/(}\ytyp{h}\type{*?)testexpr/io}\par
\type{/t(}\ytyp{a}\type{*?)estexpr/io}\par
\type{/te(}\ytyp{n}\type{*?)stexpr/io}\par
\type{/tes(}\ytyp{s}\type{*?)texpr/io}\par
\type{/test(}\ytyp{h}\type{*?)expr/io}\par
\type{/teste(}\ytyp{a}\type{*?)xpr/io}\par
\type{/testex(}\ytyp{g}\type{*?)pr/io}\par
\type{/testexp(}\ytyp{e}\type{*?)r/io}\par
\type{/testexpr(}\ytyp{n}\type{*?)/io}\par
\stopbuffer

\setupcolors[state=start]

\definelayer
   [TitleGraphic]
   [width=\paperwidth,
    height=\paperheight]

\setlayer
   [TitleGraphic]
   [preset=lefttop]
   {\scale
      [width=\paperwidth,
       height=\paperheight]
      {\framed
         [frame=off,
          offset=overlay,
          background=color,
          backgroundcolor=blue,
          foregroundcolor=red,
          align=normal]
%         {\setuptyping[before=,after=]\typebuffer[title]}}}
         {\getbuffer[title]}}}

\setupbackgrounds[page][background=TitleGraphic]

\starttext

\startstandardmakeup

\stopstandardmakeup

\stoptext
