[NTG-context] TeX "matrix" command not working since update

2016-04-09 Thread L.S.-Soc 

Hi guys,

i've already searched the mailing list for this but i still am having a 
problem while trying to create a matrix.

my code looks like this:

\startformula
S=\left(*\matrix**{*
  \sigma_x *&* \tau_{xy} *&* \tau_{xz} *\cr*
  \tau_{yx} *&* \sigma_y *&* \tau_{yz} *\cr*
\tau_{zx} *&* \tau_{zy} *&* \sigma_z *\cr*
*}*\right)_{xyz}
\stopformula

But since a few days, there are only empty braces after compilation. The 
funny thing is, i worked already. but i've updated context at least once 
since (only 5 days ago, betas included) and since then after compiling 
there are only empty braces. When i enter


\startformula
S=\left(
1234
\right)_{xyz}
\stopformula

the 1234 shows fine between the braces. so it seems to have to do with 
\matrix command in some way...
i don't know any alternative way to create a matrix. any help would be 
appreciated.



Greetings,

Sebastian

Especially Adobe Acrobat Reader DC.

When the PDF file is closed in the Reader, a list of recent files is displayed 
instead. The most recent one is selected and its thumbnail is displayed in the 
right pane. From my experience as long as this thumbnail is displayed, the PDF 
file is locked for any modifications (!) Really silly from Adobe developers.

My advice is to either close Reader completely or select another item in the 
recent opened documents.

[NTG-context] defining a comamnd as variable which behaves as constant

2016-04-09 Thread Pablo Rodriguez 
Dear list,

I have the following document:

\mainlanguage[es]
\starttext
\startTEXpage[offset=1em]
\dorecurse{27}%
{\def\abcd{\convertnumber{a}{\recurselevel}}%
\dorecurse{27}%
{\abcd\convertnumber{a}{\recurselevel} }\par}
\stopTEXpage
\stoptext

I want to test all lowercase-letter pairs in Spanish.

Excuse me for my missing programming notions. For the sample above, I
would need a command that behaves as a variable when defined, but as a
constant when invoked.

Is there any way to achieve that without using counters? Sorry if there
is too much nonsense in the previous paragraph. But I need to know how
to do it for another example too.

Many thanks for your help,

Pablo

Hi Lukáš,

this wuld be the way to do it:

   context source.tex --result=output

I’m not sure it may work with Adobe, since it compiles source.pdf and
then it moves to output.pdf

BTW, ---auto may achieve what you intend. I have never used it.

Just in case it may help,

As far as I know, this is only an issue for Adobe users...

At work, I have SumatraPDF running under Win7 and it reloads the PDF
document when it has been recompiled.

[NTG-context] Weird background colors in autogenerated index

2016-04-09 Thread Jan Tosovsky 
Dear All,

since LuaTeXt 0.81 my back-of-the-book index (register) is generated with
strange background colors. The index title is typeset in yellowish
background and the left column of the last index page has a blue background,
see the attachment.

I've thought I reported it, but it is still there even in 0.95. It was fine
in the version 0.80.

Could this be somehow eliminated?

Thanks, Jan

[NTG-context] Redirect compilation to another .pdf?

2016-04-09 Thread Lukáš Procházka 

Hello,

is there a way to tell ConTeXt to generate a .pdf named otherwise instead of 
the name derived from file to be compiled?

Let's have A.tex to be compiled and an existing A.pdf which cannot be written 
into, e.g. due to being open by a viewer.

The "context.exe A.tex" fails as the A.pdf cannot be open for writing.

The "context.exe A.tex --result=A2.pdf" fails too, as Ctx tries to write into 
A.pdf (derived from A.tex) first and later tries to rename A.pdf to A2.pdf.

There is a way - "copy /y A.tex A2.tex & context.exe A2.tex" but it has some disadvantages - the 
.log, .tuc etc. will be named A2.log, A2.tuc etc., messages will refer to "A2" rather than to 
"A" etc.

So best seems to me to have an option to tell ConTeXt to produce a .PDF WITH A 
DESIRED NAME from the beginning... Is there a way to do so?

Best regards,

Lukas

[NTG-context] Ligature color is not reliable

2016-04-09 Thread Jan Tosovsky 
Dear All,

for an illustration I wanted to colorize all ligatures, but the following
method is not reliable for three character ligatures - which ends up black.

While tested with Palatino, it can be simulated even with a default font
(however there are missing ffi and ffl ligatures).

\definefontfamily[palatino][rm][Palatino Linotype][features={default,
quality}]
\setupbodyfont[palatino]

\starttext
Je{\red ff}, the o{\red ffi}ce on the {\red fi}rst {\red fl}oor is o{\red
ffl}ine.
\stoptext

What is happening here? 

Thanks, Jan
