Re: [NTG-context] mathalignment vs mathmatrix

2017-09-08 Thread Henri 
You obviously didn't read my first mailing correctly and copied an incomplete 
version of my MWE. The
definitions of \Up and \Dn are right there before \starttext.  Whether the 
mathmatrix is empty of
not does not make a difference.  For the sake of completeness I present you a 
different MWE below
which incorporates your requested changes.  Fails with 2017.09.07 23:44 (It 
worked before, so your
version 2017.09.05 15:10 seems to be unaffected).

Re: [NTG-context] Expandable \doifelse tests

2017-09-08 Thread Meer, Hans van der 
While going through the posts I had stowed away because I found them 
interesting, I came along this one.
There is not a problem here, just a tiny observation.

In order to work
   \doifelse{a}{\doifelse{x}{x}{a}{b}}{yes}{no}
properly it is sufficient that the inner \doifelse is of the expandable kind.

Thus
   \doifelse{a}{\expdoifelse{x}{x}{a}{b}}{yes}{no}
yields the same as
  \expdoifelse{a}{\expdoifelse{x}{x}{a}{b}}{yes}{no}

Dear list,

Motivated by this question on TeX.SX 
https://tex.stackexchange.com/questions/370868 I was fiddling around with the 
\doifelse conditionals. I noticed that most of them are not expandable, which 
makes it very difficult to concatenate them. Here a simple example

\starttext

\doifelse{a}{%
\doifelse{x}{x}{a}{b}% <- evaluates to "a" but not expandable
}{yes}{no}

\stoptext

This outputs "no" even though "a" is equal to "a".

Would it be possible to substitute these conditionals by expandable ones? I 
would volunteer to help make them expandable.

Cheers, Henri

I am using TeXshop in OS X. So I am not sure this works in Linux system.
I hope that it may help.


Thanks for the suggestion.  Unfortunately it did not work:

luatools -generate


Note that this should be luatools --generate (two hyphens, which got 
changed to an endash in the previous email).

Re: [NTG-context] Background with rounded corners (Metafun)

2017-09-08 Thread Meer, Hans van der

I tried this example and I wonder what the  [preset=lefttop] does. Because 
whatever I fill in for lefttop, the ornament appears always in the topleft 
corner and nowhere else.

Thanks for the suggestion.  Unfortunately it did not work:

luatools -generate

resolvers   | trees | analyzing 'home:texmf'
resolvers   | globbing | confusing filename, name: 'README.txt', lower: 
'readme.txt', already: 'ReadMe.txt'
mtxrun  | unknown script 'base.lua' or 'mtx-base.lua'

But never mind, I can work round the issue that caused the need for the
old binaries.

Re: [NTG-context] mathalignment vs mathmatrix

2017-09-08 Thread Otared Kavian 
Hi Henri,

I think your code has a problem: the first one is that the definition of \Up 
and \Down is not understood when I compile your example, and then you introduce 
an empty mathmatrix which creates a difficulty too.
Once I remove the definitions of \Up and \Dn  the code is typeset (ConTeXt  
ver: 2017.09.05 15:10 MKIV beta).
Can you please give a more detailed example where you see the problem?

Best regards: OK
