I am not sure whether `delimiter` is the best key. I think that `scale` 
may be better, but using `scale` for specifying the scaling of math 
delimiters will be inconsistent with how `scale` is used everywhere else. 
Another option is to use `alternative` key.


it would be something factor=2 or so, not the funny XxXxxxXX kind of flags


Sure. factor=(auto|none|1|2|3|4) is also ok (and would be directly mapped 
to choosemathbig).

ok, that makes sense.

well i do need the description as the items are not numbered or annotated in a 
sequential way.

i could use a \sym{tag} but then the available space is constant, and not 
variable as is when using description.

Or is there a better (simpler) way?

You can see from your log that
context --pdftext
is running the MKII macros and
context
is running MKIV macros. The two systems are very different, MKII being
"frozen" and MKIV having evolved in some ways significantly. It is not
a question of TeX engines, but rather of entire systems.

But it sounds like you want to be using an itemize or enumeration
rather than a description.

\startitemize [n]
  \startitem one
 \startitemize [a]
 \startitem two \stopitem
 \startitem three \stopitem

mkii or mkiv?

(pdftex is mkii, luatex is usually mkiv)

The incorrect nesting seems to be connected to the luatex engine.
If i have the same source compiled by pdftex, it works as intended.

So is the different rendering an intended feature of luatex, or a simple bug?

Perhaps not the best answer, but exiftool can add that metadata after the fact.

[NTG-context] pdfinfo

2017-03-07 Thread Csikos Bela 
Dear context users:

In latex I could use \pdfinfo command to add information metadata to pdf file:
Title, Author, Creator, Producer, CreationDate, ModDate, Subject, Keywords.
I found that I can set title, author, subtitle (=subject) and keyword with
\setupinteractions command.

How can I set the remaining ones (CreationDate, ModDate, Creator, Producer)?

Thank you in advance,

bcsikos

Re: [NTG-context] Manually scaling math fences

Hi Aditya,

I agree totally with you and support your suggestion…
Maybe instead of the « delimiter » keyword, one could introduce a keyword such 
as « size »:


\MEAN[size=auto] expands to \left\langle .. \right\langle
\MEAN[size=] expands to \langle .. \rangle
\MEAN[size=big]  expands to \big\langle  ... \big\rangle
\MEAN[size=Big]  expands to \Big\langle  ... \Big\rangle
\MEAN[size=bigg] expands to \bigg\langle ... \bigg\rangle
\MEAN[size=Bigg] expands to \Bigg\langle ... \Bigg\rangle


with integrals we have factor as key ... anyway, i'll look into it (not 
in the middle of something else) .. luatex actually has a bitmore 
control over these matters built in



Best regards: OK

Hi Hans,

There are instances where the automatic scaling provided by \left and \right is 
not ideal and one has to use manual scaling. For example:

\starttext
\startTEXpage \startformula
 \left\langle \sum_{i=1}^n A_i x_i \right\rangle
 \hbox{ vs. }
 \bigg\langle \sum_{i=1}^n A_i x_i \bigg\rangle
\stopformula \stopTEXpage
\stoptext

Currently, math fences always default to using \left and \right, which can lead 
to undesirable results. For example:

\definemathfence [MEAN] [angle] [command=yes, color=blue]

\starttext
\startTEXpage \startformula
 \MEAN{ \sum_{i = 1}^n A_i x_i }
 \hbox{ vs. }
 \bigg\langle \sum_{i=1}^n A_i x_i \bigg\rangle
\stopformula \stopTEXpage
\stoptext

Could we add an option to \definefence that allows the user to select the 
delimiter scaling using a key (say, `delimiter`) so that

\MEAN[delimiter=auto] expands to \left\langle .. \right\langle
\MEAN[delimiter=] expands to \langle .. \rangle
\MEAN[delimiter=big]  expands to \big\langle  ... \big\rangle
\MEAN[delimiter=Big]  expands to \Big\langle  ... \Big\rangle
\MEAN[delimiter=bigg] expands to \bigg\langle ... \bigg\rangle
\MEAN[delimiter=Bigg] expands to \Bigg\langle ... \Bigg\rangle
