Layout stuff

Layout stuff

[Adam Lindsay]

Hi all.

I've been trying to get layouts working, and wanted to verify some things
(as I haven't really worked much in that space before).

Is there any way to "inherit" a layout's parameters, such as:
\definelayout [preset-1-1]      [mypresettomodify]
 \setuplayout [mypresettomodify][width=65\averagecharwidth]

(I finally figured out how to do what I want another way, but the
question is still interesting to me.)

Is the only way to activate a doublesided page layout though the page
numbering mechanism?

Thanks,
adam

no, but you can set up left and right page layouts etc

\setuplayout[odd|even|pagenumber|yourownid]

Yeah, I just stumbled across the even/odd thing earlier this week. Oddly,
it didn't seem to respect the offset parameter, which would have been the
most useful for the problem at hand.

Ah. Thanks for verifying it. I saw this line in page-lay, and wondered/hoped:
\setuplayout[
            \c!location=, % \v!singlesided, but empty is signal
            ]

Hello out there,

I don't quite understand how to use the even/odd keywords in
setuplayout:

\setuppagenumbering[alternative=doublesided]
\setuplayout[odd][width=5cm]
\setuplayout[even][width=10cm]
\starttext
\dorecurse{20}{\input knuth \endgraf \input tufte \endgraf}
\stoptext

has the same width on all pages.

I would wonder if it can be possible since changing paragraph width from 
page to page is *very* complicated task in TeX.

You are right, but we all know Hans, he does some things that are
*very* complicated in TeX.

And I see that part of my question has been answered before. It is a
matter if \definelayout[odd], \definelayout[even] and alike. I was
confused because Hans mentioned in this thread:

\setuplayout[odd|even|pagenumber|yourownid]

Which I can't get to work here.

This should work. I have been been testing a lot of different
possiblities with layout, and am writing a complete new doc to
illustrate just these problems. If this code doesn't work, let me know;
it means I have forgotten a line here or there.

However, it is also true that you can't get TeX to change widths of
paragraphs from one page to the next. (That is, as far as I know.) I
posted this problem about a week ago, and no one has responded, leaving
me to believe you can't to it in  ConTeXt (or TeX). I posted the problem
in the wiki section in the bugs page.

 \definelayout[even][
  leftmargin=30mm,
  rightmargin=25mm,
  cutspace=50mm,
  backspace=40mm,
  height=fit,
  width=fit,

 \definelayout[odd][
  leftmargin=25mm,
  rightmargin=30mm,
  cutspace=50mm,
  backspace=40mm,
  height=fit,
  width=fit,
  ]

\definelayout \neq \setuplayout?

(I got it to work with your \definelayout example, but not with Hans'
\setuplayout command)

There is, of course, \parshape. And I know that Hans does a lot of
paragraph trickery (see for example coloumns).

If you can get pages with different widths to work, please let me know!
Like I said, I posted the problematic code in the wiki. It would be
great to get this to work.

for controlled situations it's doable by setting the parshape

so, for novels you can use:

\startsetups [grid] [*default]
   \nopenalties
\stopsetups

\setuppagenumbering
   [alternative=doublesided]

\setuplayout
   [grid=yes]

\definelayout
   [odd]
   [width=10cm,
    lines=40]

\definelayout
   [even]
   [width=8cm,
    lines=40]

\setuplayout
   [odd]

\setuptolerance
   [verytolerant]

\showframe

\def\SetLineWidths
   {\scratchtoks \emptytoks
    \ifdim\pagegoal=\maxdimen
      \scratchdimen\textheight
      \ifodd\realpageno
        \noflines\namedlayoutparameter{odd}{lines}%
      \else
        \noflines\namedlayoutparameter{even}{lines}%
      \fi
    \else
      \scratchdimen\dimexpr\pagegoal-\pagetotal\relax
      \advance\scratchdimen-\topskipgap
      \getnoflines\scratchdimen
    \fi
    \ifdim\scratchdimen<\lineheight
      \page
    \else
      \scratchcounter\noflines\relax
      \ifodd\realpageno
        \doSetLineWidths{odd}{even}%
      \else
        \doSetLineWidths{even}{odd}%
      \fi
      \parshape \scratchcounter \the\scratchtoks \relax \ignorespaces
    \fi}

\def\doSetLineWidths#1#2%
   {\dorecurse\noflines
      {\appendetoks 0cm \namedlayoutparameter{#1}{width} \to\scratchtoks}%
    \dorecurse{2}
      {\advance\scratchcounter\namedlayoutparameter{#2}{lines}\relax
       \dorecurse{\namedlayoutparameter{#2}{lines}}
         {\appendetoks 0cm \namedlayoutparameter{#2}{width} \to\scratchtoks}%
       \advance\scratchcounter\namedlayoutparameter{#1}{lines}\relax
       \dorecurse{\namedlayoutparameter{#1}{lines}}
         {\appendetoks 0cm \namedlayoutparameter{#1}{width} \to\scratchtoks}}}

\dontcomplain

\EveryPar{\SetLineWidths}

\starttext

\dorecurse{25}{\dorecurse{4}{\input tufte }\par}

\stoptext

no guarantees, no kernel stuff either, maybe some fun module
