You can let each card produce a single page (select a small aper size, e.g. A7) 
and use the imposition mechanism
to print many cards on paper. I wrote a while ago a imposition shame for 
flashcards which can be used for this.

One of these examples can be found in the TeXbook on page 65.

IIRC a few presentations regardings math used boxes to show the position
of the various symbols and the needed kerns for sub- and superscripts etc.

Link to the This Way that introduces \fakeword and friends:

(I am personally rather fond of the \simplethesis command. (This
command produces a lot of output, so it may take a bit longer than you
expect --- just like a real thesis.))

Or perhaps you mean the black boxes in section 5 of the reference
manual's typography chapter [1]? Those are made by replacing every
letter with a black rule of equal height, depths, and width. I dug op
the code [2]; relevant bit is below.

Re: [NTG-context] partial derivatives with bonum/pagella font

Thank you very much Sietse! This fits my needs for the students for

I also defined
\def\sprime{\myprime{\prime}}
\def\dprime{\myprime{\prime\kern-0.1em\prime}}

Then $f\sprime_x$ and $f\dprime_{xx}$ is not too hard to write :)

You can use the \TB which accepts the same keywords as \blank.

\starttext

\starttabulate
\NC one  \NC two   \NC\NR 
\NC two  \NC three \NC\NR 
\TB[line]

[NTG-context] Tabulate: vertical distance between rows

[Procházka Lukáš Ing . - Pontex s . r . o .]

Hello,

are there more ways how to affect vertical distance between rows within 
\start/stop-tabulate?

1) There is one, described on wiki (http://wiki.contextgarden.net/Tabulate):


\unprotect
\appendtoks
  \blank[halfline]
\to \t_tabl_tabulate_every_after_row
\protect

...


Its problem is that I don't know how to call it by Lua.
The following code fails:


  \startluacode
context[[
\unprotect
\appendtoks
  \blank[halfline]
\to \t_tabl_tabulate_every_after_row
\protect
]]
  \stopluacode

...


So how to make it acceptable by Ctx?


2) Is there another way, e.g. inserting something each time before \NC\NR or 
elsewhere)?

This brings no effect:


  \starttabulate[|l|r|]
\NC a \NC b \blank\NC\blank\NR
\NC A \NC B \NC\NR
  \stoptabulate


As I intend to typeset a table (into tabulate) via Lua, adding an extra 
sequence/command anywhere when a table row is typeset is no problem.

Questions are: a) what would be such sequence and b) where it should be placed?


My whole testing code is attached.

Thank you in advance.

Best regards,

Lukas

I don't know if it is possible and can not estimate how much work it 
represents but maybe one can consider to merge the digit part of the \digits 
and \unit code.
The \unit command would then use the same code as the \digit one to format the 
digit part. Then, the \unit code would use a specific code to format the unit 
part.
This would make it possible to configure the digit formatting with one unique 
command for both \unit and \digit and another command would be used to 
configure the formating of the unit part.

This might get you somewhere. I hope you don't have too many double
primes in your document...

NB: `%macros=mkvi` has to be the first line in the file.

Re: [NTG-context] partial derivatives with bonum/pagella font

[Mikael P. Sundqvist]

OK!

is there a quick fix/hack that somehow allows me to get it look "almost
like it should" in a small document today with bonum? I'll give a
presentation tomorrow, and if this is not the case I'll change the notation
of partial derivative to the one using \partial instead...

cambria is the benchmark ... indeed bonum looks somewhat weird (also 
because the f is rather tightly bounded; the same with pagella)


(there are some primes-*.tex test files in the test suite)

the primes mechanism is somewhat non-trivial as ' is not really the 
prime symbol and some additional parsing / hackery happens; also, 
traditionally primes in tex sit on the baseline and need to be lifted


one problem is that texgyre math is still beta so messing around at the 
tex end will interfere with improvements

Re: [NTG-context] \digits get \times instead of \cdot before exponent

[Hans Hagen]

On 5/21/2013 11:35 PM, Romain Diss wrote:

We've already got \setdigitmode, \setdigitorder, and \setdigitspace;
it might make sense to create a \setupdigits to consolidate these
setups into one interface. Something like this:

\setupdigits
[mode=4,   % -->\setdigitmode{4}
   % (decimal period, thinspace between groups)
 inputdecimalmark={,}, % -->\setdigitorder{0}
 signspace=yes,% -->\setdigitsign{1}; '+ 1.4', not '+1.4'
 times=\times, % or times=\cdot
 ]



+1



P.s: I've been thinking I'd like to write more contexty interface that
doesn't use predefined modes, but lets you setup the decimal mark,
separator mark, the input decimal mark, etc. Something like this:

\setupdigits
[inputdecimal={.},  % input  3.1415926535
 decimal={,}
 separator=\space,
 groupsize=4,   % output 3,1415 9265 45
 signspace=,]   % +3.14159...

That could even tie into \setuplanguage to allow setting
language-specific defaults. Would anyone be interested in this?


+1 again!


needs a bit of thinking as when we start this route we get lots of new 
keywords (with the danger of introducing inconsistencies) so first we 
need to collect all potential candidates for such keys (e.g. using 
separator might be too generic )

[NTG-context] partial derivatives with bonum/pagella font

[Mikael P. Sundqvist]

Hi all,

The following examples give wrong space. There is a space between the prime
and the subscripted x. If I do not load the bonum font it just looks as it
should.

\setupbodyfont[bonum]
\starttext
$f'_x$, $f_x'$ $f\prime_x$.
\stoptext

(it does not look good with the pagella font either...)

Any ideas?

[NTG-context] Place a box on the right

[H. Özoguz]

Hi there,

\starttext

\startalignment[right] \framed{This box should be on the right side, but 
is not.} \stopalignment


\stoptext


I know it is easy, but could not find it in the reference. Why not allow 
simply \framed[location=right]{} ? ("right" is not a correct keyword for 
"location").
