Rest assured, we definitely have you registered as a member! Usually we send 
out the membership invoices at the end of the winter, and communication for the 
next meetings tends to pickup around easter.

It’s \setupinterlinespace, and the default is 2.8ex, so 1.3ex is too small.

sorry if i dont get your problem right understood, but i'm completely new to

I use a hack not to get the number not printed in the title page (though I

I use \setuppagenumbering[location=] for not getting the number printed and 
then I reset the page numbering for the next sections. I copy my code so that

That usually only happens in one of the column modes that requires the 
grid. It doesn’t happen in usual one-column typesetting. There must be 
something wrong in your setup.


Please make a minimal example (MWE).

2. Is there a document where I can read how the grid is conceived to 
work for the many options in a simple way?


AFAIK, the details manual is the only documentation for it.

Hi Miguel,

I don’t use the grid. This is also the default in ConTeXt.

I’m not sure whether I’m getting your point here.

See what the difference between not enabling the grid and enabling it:

  \showframe\showgrid
  \setupwhitespace[medium]
  \starttext
\input knuth
  \setuplayout[grid=yes]\page
\input knuth
  \stoptext

> 1. Why are the lines printed one over the other when grid=no? how do

As said, ConTeXt is \setuplayout[grid=no] by default.

As far as I can recall it, the default value is
\setupinterlinespace[line=2.85ex].

I have just discovered that with values such as line=1.3ex,
\setuplayout[grid=yes] behaves very differently than with values such as
line=2ex (and above).

I mean, lines follow the grid when the text fits. See the difference with:

  \showframe\showgrid
  \setupinterlinespace[line=1.3ex]
  \starttext
\dorecurse{25}{asa aeo eau}
  \setuplayout[grid=yes]\page
\dorecurse{25}{asa aeo eau}
  \stoptext

According to https://wiki.contextgarden.net/Grid_typesetting (feel free
to improve the article), a way of solving this would be to wrap your
stuff inside:

  \startlinecorrection
  ...
  \stoplinecorrection

The problem is that your interline space is too small to prevent line
collapsing.

ex is the height of the lowercase 'x'. Are you sure that your school
doesn’t require 1.3em (height of capital 'M') as interline space instead?

You can get yourself the values:

  \starttext
  \the\exheight\\
  %\the \dimexpr1.3\exheight\\
  \the\emwidth
  \stoptext

The first line will give you 1ex is about 5.7pt (with the default font
used by ConTeXt). 1.3ex would be less than 6.75pt.

The value of 1em is the value of the font size. Default for ConTeXt is
12pt, so 1em has to be 12pt.

I think it is clear now that an interline space of 1.3ex calls for line
overlapping.

That being said, I don’t know why the grid avoids collapsing them (if
the person explicitly asks for this).

See the wiki article above. The mailing list is also a way of getting help.

One suggestion, please always provide a minimal working sample (that can
be copied, pasted and compiled automatically), when you ask for help.

How minimal? Well, they cannot lack essential parts to be compiled.
Other than that, they should only contain required content to reproduce
your issue.

This minimal working sample helps the one who reads to understand what
you are dealing with.

Otherwise, it is really hard to understand which kind of issue you might
be facing (consider that no one else may read your mind or be in front
of your computer).

I hope it might help,

Pablo

[NTG-context] learning about the grid

[Miguel Diaz]

Hi everyone,
being a newbie I just discovered how different setups for the grid may
affect my (very simple) document.
In the Details manual (which of course I don't understand because of my
unexperience) I read that many people don't use the grid, but when I
configure grid=no the whole lines of a section are printed one over the
other.
Playing with the options and setupinterlinespace I got the unhappily
desired 1.3ex that may school requieres for the teaching programs
(grid=line, interlinespace=1.3ex), but I somehow feel that's not the right
way to go.

1. Why are the lines printed one over the other when grid=no? how do profis
then use context without grid?

2. Is there a document where I can read how the grid is conceived to work
for the many options in a simple way?

thanks in advance

There is nothing you can do here for the moment, the empty page is caused
by a new piece of code in page-lay.mkxl (see below) to go to the next 
odd page

when you use the \setuppagenumbering command.
