Grid-keeping list (again)

Grid-keeping list (again)

[Johannes Kuester]

[-- Attachment #1: Type: text/plain, Size: 1479 bytes --]

Hello,

I'm still trying to typeset a "grid-keeping" list (or table).
Wolfgang Schuster supplied me off-list with the attached module.
This works fine except for one problem:

Only the first few lines are placed on the grid, then the grid is lost.

After the next pass (i.e. after the next "texmfstart texexec testfile"),
some more lines are placed on the grid.
(So I need many passes to typeset the complete list correctly).

Why? Any idea?

(I fiddled around with \synchronizegrid, \placeongrid, \moveongrid, and
\startlinecorrection \stoplinecorrection, but none of these seems to work.)

You could try the effect with the following example:

%%%%%%%%%%

\setuplayout[grid=yes, columns=2]
\showgrid
%\showstruts

\usemodule[gridlist]

\starttext

\startcolumns[n=2, balance=no]
%% (columns are not necessary to show the effect)

\dorecurse{20}{
  \zeichen{0001}{a}{first letter}{}%
  \zeichen{0002}{b}{second letter}{}%
  \zeichen{0002}{c}{third letter, this one has a longer entry
                    which needs more than one line}{}%
}

\stopcolumns

\stoptext

%%%%%%%%%%


(This should result in an annotated list of mathematical symbols,
showing the Unicode number, the math symbol, and some explanation (and
where the explanation could need more than one line); quite similar to
the list I published in "Detailtypografie" (2nd ed. 2004), but for
another -- quite pressing -- project.)

Sorry, no answer.
Only to say that I'm following this subject, and I'm doing some private tests.

Hi Johannes,

replace the current definition of \zeichenzelle with the following:

\def\zeichenzelle#1%
  {\advance\zeichencolumn\plusone
   \hbox
     {\vtop
        {\hsize\zeichenparameter\c!width
         \normalbaselines
         \zeichenparameter\c!before
         \begstrut
           \dostartattributes{\????ze\number\zeichencolumn}\c!style\c!color
           \zeichenparameter\c!left
             #1
           \zeichenparameter\c!right
           \dostopattributes
         \endstrut
         \zeichenparameter\c!after}}}

\synchronizegrid in \setupzeichen is not neccessary

\setupzeichen
  [\c!textwidth=63.8833mm,
   \c!before=\noindenting, %\synchronizegrid,
   \c!after=, %\synchronizegrid
  ]

add the next two commands to your module

\def\startzeichen{\begingroup\offinterlineskip}
\def\stopzeichen{\endgroup}

a alternative version

%\def\startzeichen{\offinterlineskip}
%\def\stopzeichen{\oninterlineskip}

and put \startzeichen and \stopzeichen before and after your lines
with all \zeichen commands

\startzeichen
\zeichen
...
\zeichen
\stopzeichen

and everything should work as expected

Wolfgang

Thank you! I hope you will be more successful than I am.

I do not understand why this is such a problem. Basically, it's just
about "paragraph boxes" and their proper alignment on a grid.

To me, such a list seems like a basic typographic requirement, so it
should be possible to do that in ConTeXt.

the problem with tex is that it does not hav ea way to force consistent height and depth of lines, so here are a few tricks: 
 
\begstrut some text \endstrut \endgraf 

\snaptogrid\vbox{some text}

yes, it'true.
And this is why I'm so involved.

Yes, it does, definitely. So it's my (or any other user's)
responsibility that the cells contain only "allowed" stuff.

I still have to see how to deal with large symbols (bigops and
integrals). Maybe with "\blank[medium]" in between (and some "\smash"),
so that every second line will be on the grid again.

When I typeset a similar list previously (for Detailtypografie), I still
did that in LaTeX. That required a lot of trickery and manual
correction, but at least I was able to do it (and yes, it was arranged
on a grid, but LaTeX didn't know that).

That is currently my main conceptual problem with ConTeXt: sometimes
it's too high-level and too clever, and it's hard to figure out how to
do the trickery and the tweaking ...

Maybe a strategy is to use a vbox with ht+dp multiple of a grid space
...but the first line of every page has another height....
I have posted something with bTABLE last days under this topic

There are many pdf about context;
I try to have a 'programmer view' of these things.
Among others, see and criticize

there is some some gridmath support available; see details.pdf

Yes, I know, I use that already.
Very helpful for my display formulas.
I didn't try it yet on my symbols list, here the module from Wolfgang
and blanks will do, I think.

Each first line will be some heading, so that's not a problem in my case.

My grid-keeping list problem is solved, the module by Wolfgang serves my
purpose very well.

Nice and interesting (although I didn't had enough time to look at it
thoroughly).

I'm aware of all the pdf manuals, and I use the wiki, source browser,
mailing list + archive.

Still it's sometimes hard to find one's way through.
But on to my next problems ...
