Help on tweaking alignment, page numbers and ToC

Help on tweaking alignment, page numbers and ToC

[Nicola]

Hi,
first of all, let me say *thank you* for the vast improvements on
ConTeXt Garden! Browsing the documentation and finding stuff is so
much easier and pleasant than it used to be (also the site seems
faster).

Thanks to the docs, dropcaps and protrusion have no secrets for me,
but I am still struggling with some basic tasks (see the document
below):

0. Push text to the bottom of the text area (see copyright).
1. Increase the space between Roman numbers and titles in the ToC.
2. Vertically center the ToC (wrt to the text area).
3. Suppress page numbers and headers in all blank pages.
4. Suppress headers in the front matter.
5. Style and position page numbers differently in the front and body
   matter (e.g., centered only in the front matter).

As my full document uses environments, I would like most setups to
be in the environment, if possible. E.g., is it possible to replace

    \setuphead[chapter][after={}]

(see below) with an environment setup that applies only to the ToC?

Hi Nicola,

Garulfo invested a lot of time and effort in the new wiki layout and
contents.

Taco is always improving the software that runs the wiki (and the source).

Many thanks to them and to all other developers.

Well, \setupalignment tweaks position in line (I’d rather say). Bottom
isn’t an option there.

Adding \null\vfill before the alignment does the job.

distance with dimension is the key in \setuplist.

Use a makeup for the TOC (if and only if it takes a single page).

Break pages with \page[yes, blank].

> 4. Suppress headers in the front matter.

This would be my educated guess:

  \startsectionblockenvironment[frontpart]
     \setupheader[state=stop]
  \stopsectionblockenvironment

> 5. Style and position page numbers differently in the front and body

Alignment only (style comes with the proper option 😉):

  \setuppagenumbering[location={bottom, inmargin}]

  \startsectionblockenvironment[frontpart]
    \setuppagenumbering[location={bottom, centered}]
  \stopsectionblockenvironment

Either you create and set up a \chapter command for the TOC (such as
\chapterTOC) to use it only once, or you create a sectionblock that you
apply only for the TOC (and define the chapter settings for that
sectionblock).

I never used environments (other than the ones to typeset XML sources),
so this is my best option 😅.

I hope it helps,

Pablo

I think a makeup environment fits here better.

\definemakeup
   [copyright]
   [page=yes,
    pagestate=start,
    doublesided=no,
    align=flushright,
    bottom=]

\startmakeup[copyright]

\stopmakeup

Correct but it's also important to set "width" to a value which is large 
enough to fit the number.

Not the best solution for empty pages before a new chapter.

\setuphead
   [chapter]
   [page={yes,header,footer,right}]

A environment is nothing more than a external file for the style, the 
only difference between \input{...} and \environment[...] is that 
ConTeXt loads environment files only once.

Re: Help on tweaking alignment, page numbers and ToC

[Nicola]

Thank Pablo, Wolfgang,
I have learned more by reading your replies than by myself in the rest
of the afternoon. Just one more thing:

>>> 1. Increase the space between Roman numbers and titles in the ToC.
>>
>> distance with dimension is the key in \setuplist.
>

Chapters in the front matter have no number, so the Preface gets aligned
with the numbers of the other chapters:

Preface
   I     XYZ
  ...
VIII     XYZ
  ...

I'd prefer all the titles to be aligned:

         Preface
   I     XYZ
  ...
VIII     XYZ
  ...

I have tried to do my homework by playing with \setuphead, but I am
afraid I need your help on this.

Nicola

Hi Nicola,

if you found replies useful, please update the wiki (this may help others).

Sorry, but too tired to type a sample.

How about setting distance for \setuplist[chapter] in the sectionblock
frontpart with the desired width?

I hope it helps,

Pablo

When I copied the code, I removed right from the \page.

Now I realize that without page, that pagebreak is almost useless.

That does not seem to change the layout, unfortunately. I have tried
with `margin` and `aligntitle` as well:

\setuplist[chapter][distance=1cm,aligntitle=yes]
\startsectionblockenvironment[frontpart]
\setuplist[chapter][aligntitle=yes,margin=2cm,distance=2cm]
\stopsectionblockenvironment

I'll take a fresh look tomorrow.

Nicola

When you a unnumbered section with the list alternatives a-c your're out 
of luck with the regular \setuplist options because it always use a 
width of 0pt for regular section number. The aligntitle works only for 
numbered entries to align them when you disable the number entry in the TOC.

To show the section entry and align all entries on the same line you can 
use the following method:

   1. Set the width and distance for the section number to 0pt.

   2. Set the margin key to a value large enough to fit all numbers

   3. Apply a command to the numbercommand key where you shift the 
number to the left in the margin area you set in the previous step

%%%% begin example
\define[1]\ChapterListNumbercommand
   {\offset[x=-1cm,width=0pt]{\simplealignedbox{1cm}{flushleft}{#1}}}

\setuplist
   [chapter]
   [distance=0cm,
    width=0cm,
    margin=1cm,
    numbercommand=\ChapterListNumbercommand]

\starttext

\startfrontmatter
   \completecontent
   \chapter{Preface}
\stopfrontmatter

\startbodymatter
   \chapter{Introduction}
   \chapter{Workflow}
   \chapter{Input}
   \chapter{Output}
\stopbodymatter

\startbackmatter
   \chapter{Index}
\stopbackmatter

\stoptext
%%%% end example

Re: Help on tweaking alignment, page numbers and ToC

Hi,
I still have an issue with blank pages...

>> 2. Vertically center the ToC (wrt to the text area).
>

Yes, the ToC takes a single page. The makeup seems to insert a blank
page afterwards. MWE:

    \setuppagenumbering[alternative=doublesided]
    \definemakeup[ToC][align=middle,pagestate=start]
    \starttext
    \startfrontmatter
      \startmakeup[ToC]
        \placecontent
      \stopmakeup
      \input{knuth}
    \stopfrontmatter
    \startbodymatter
      \dorecurse{10}{\chapter{Foo}}
    \stopbodymatter
    \stoptext

How do I suppress the blank page after the ToC?

Nicola

Hi Nicola,

all makeups do that by default.

"doublesided=no" is what you need.

My warning about only taking a page is that makeups don’t split content
in pages.

I hope it helps,

Thanks. That works with my MWE, but in my document I actually have
a chapter, and chapters start on the right page, even if I add page=no
to \setuppagenumbering:

    \setuppagenumbering[alternative=doublesided,page=no]
    \definemakeup[ToC][align=middle,pagestate=start,doublesided=no]
    \starttext
    \startfrontmatter
      \startmakeup[ToC]
        \placecontent
      \stopmakeup
      \chapter{Preface}
    \stopfrontmatter
    \startbodymatter
      \dorecurse{10}{\chapter{Foo}}
    \stopbodymatter
    \stoptext

I have no idea how to allow chapters to start at arbitrary pages when
alternative=doublesided.

Nicola

Use \page[yes, blank] instead of \page[yes, blank, right].

Can you start a new thread when you have a new question. When other
people have the same problem they can see on the subject if this is
the right thread to find a solution for it.

The page key in \setuppagenumbering is used to add the final page
in a doublesided document to have a even number of pages.

Thank you both. I had tried `yes` already, but I had mixed it with other
interfering settings, which got me confused. Now that I have cleand up
my code, everything is as expected.
