Hi,

So … the server now runs Ubuntu 22.04. Jay!
This was a much harder upgrade though.

In any case, today was the last of the big software update procedures

Re: [NTG-context] what happend to \writeline?

Hello Hans,

you can wrap such a patch in:

if I do this, I get:

and if I use \withcaron, then the wrapper seems to be OK,
but the patch isn't loaded any more.
Wasn't the patch meant to override an already existing\xtableflushsplit

Re: [NTG-context] Side-by-side environment

[Werner Hennrich]

Hello Tommy,
xtable is quite versatile and can do a lot of things -
place your cells next to each other by putting them into the same row.

If you haven't yet, this might be a good moment to skim through the
xtables manual
 and play
around,
for the full list of options refer to the commands reference
.

All the best!

Re: [NTG-context] new page before xtable with repeated headers

[Werner Hennrich]

I still rely in all my installations on this bit at the bottom to be in
cont-new.mkxl.
Is there a way to make this patch update-safe?

There are comments
in ./tex/texmf-context/tex/context/base/mkxl/cont-new.mkxl:

   %D This file is loaded at runtime, thereby providing an excellent
   place for hacks,
   %D patches, extensions and new features. There can be local
   overloads in cont-loc
   %D (which has always been the case) and experimental code in
   cont-exp (which is also
   %D so old that I need to remind myself to check it occasionally, so
   here is the
   %D reminder).

I tried the mentioned local overload methods but didn't get them to work.
Did I mess up somehow or is the comment above outdated?
Are there any better ways - update-safe though?

Thanks a lot, Werner

[NTG-context] what happend to \writeline?

[Werner Hennrich]

Hello everyone,

I'm looking into my environment's logging to trace a problem and realize
that \writeline is gone mute -
that is, the output of subsequent logging lines now gets joined up in
the same line, very hard to read...

I observe this in version: 2021.05.27 14:15, as well as in version:
2021.05.27 14:15
the last one I used where \writeline did write (and end) the logging
line was version: 2021.03.17 17:46.

   \def\log#1{
   \message{ logging: #1}
   \writeline
   logging #1\par
   }
   \starttext
   \log{the}
   \log{quick}
   \log{brown}
   \log{fox}
   \stoptext

used to log like this:

   logging: the
   logging: quick
   logging: brown
   logging: fox

but now:

logging: the logging: quick logging: brown logging: fox

Any idea how I can switch back the old behavior (on the new lmtx)?

Thanks you,
Werner

[NTG-context] new page before xtable with repeated headers

[Werner Hennrich]

Hello everyone,

I'm having an xtable spanning several pages and need to have its headers
repeated.

For this I've set "split=repeat", but unfortunately this causes the
table to start with a new new page leaving the rest of the preceding
page empty. Having "split=yes" makes the tabe continue on the previous
page as a need it to, but then the header isn't repeated any longer.

I realize that there has been a very similar question already in
https://www.mail-archive.com/ntg-context@ntg.nl/msg93775.html, but my
problem happens isolated in a very clean situation w/o any header,
floats or the like - and I don't see yet how I can get this working in
my situation. Any help is highly appreciated, here is a MWE of my problem:

\definextable[mytable]
\setupxtable[mytable]
[
option=max,
split=repeat,
%split=yes,
header=repeat,
width=\textwidth
]
\definextable[mytable:header]
\setupxtable[mytable:header]
[
foregroundstyle=\bf,
foregroundcolor=darkred,
]
% ==
\startdocument
\dorecurse{2} {
\input tufte
\vskip7mm
}
\startxtable[mytable]
\startxtablehead
\startxrow[mytable:header]
\startxcell Some Header \stopxcell
\startxcell More Header \stopxcell
\stopxrow
\stopxtablehead
\startxtablebody
\dorecurse{10} {
\startxrow
\startxcell
{\bf (\recurselevel) some tale:}

Re: [NTG-context] working on page refs with MP

[Werner Hennrich]

yes I had realized this already but I still don't know how to get those
page numbers down into MP - they keep being strings with macro code instead

is there a way the I can get \setupMPvariables[hdrPgs] in
\setupheadertexts[\setups{page:header}]
to be fully evaluated and stored as the page number in the MPvariables
first= and next= ??

   \startsetups page:header
    \setupMPvariables[hdrPgs]
        [curr=\pagenumber,
        first={\ref[page][\headerfirst]},
        next={\ref[page][\headernext]}]

    I've tried \expanded and \numeric without success

or alternatively in MP how would I call TeX (from MP) with a string like
"\ref[page][a]" and have the page number stored in a numeric var?

Thanks in advance,
Werner

watch closely to the previous log line ... you're missing quotes so mp
sees \ref [page] and as it ignores a \ it sees ref[page] which unless
you defined 'ref' and 'page' triggers an error

So MP gets the macro and tries array access... I tried \expanded,
\numeric, and resolving the page numbers via \ref[page][id] at the
various code levels - unsuccessfully so far - and out of wit now.

Hello Everybody,

I need to increase my header's space temporarily

unfortunately my LMTX (2021.02.02 15:49) disagrees:

 \setuppapersize[A4][A4]

 \setuplayout[header+=20mm]

This fails:

 tex error   > tex error on line XX in file ./local-layout.tex:
Undefined control sequence
 XX >> \startlocal

Do I need to load something in order to use this?
Or has it been completely removed?
And if so, is there a new alternative method to do the same thing?

I was unable to find anything on this topic
except https://www.mail-archive.com/ntg-context@ntg.nl/msg63602.html
which raises the same question already in 2012 but never answers it
IMHO.


Create a named layout (\definelayout[...]) and use it:

\setuplayout
  [header=15mm]

\definelayout
  [extraheader]
  [header=35mm]

\showframe

\starttext

\input tufte

\startlayout[extraheader]
\input tufte
\stoplayout

\input tufte

\stoptext

\doifelseinset{4}{\getvariable{mynamespace}{c}}{FOUR}{OEPS}

\doifelseinset{4}{\getvariable{mynamespace}{c}}{FOUR}{OEPS}

\doifelseinset{two}{\getvariable{mynamespace}{d}}{y}{n}

of course when you need millions of (similar) checks you might go for
another approach but this is still doable (0.02 sec per 10K on my
machien so less on yours)

Re: [NTG-context] \doassign variable - updates not picked up

[Werner Hennrich]

Am 22.01.21 um 23:46 schrieb Wolfgang Schuster:

I guess you set the value in a local group and at the end of the group
your setting is forgotten, ...


you're right Wolfgang!

I removed a \begingroup-\endgroup pair in the macro that sets the value
by calling my \setHeaderVar and now I get the updates being visible
inside the header code.


a simple change you can make is to replace
\doassign with \getgparameters which makes global settings.


I couldn't find any docu on \getgparameters except for its parameter
list (in setup-en.pdf) but what I have now will totally suffice.


A alternative to your current approach is to use the variables mechanism
to set and access values (you still have to ensure all values you set
are global).


I didn't even try the \setvariables approach now,
even though I had checked that one out before I wrote to this list
(w/out checking the begin/endgroup thing though).

Thank you very much and best regards,
Werner

[NTG-context] \doassign variable - updates not picked up

[Werner Hennrich]

Hello everyone,

I'm using ConTeXt  (ver: 2020.09.20 23:02 LMTX) and have to have
conditional page headers based on specific content criteria. To achive
this I'd like to get some global variables in TeX, change their values
several times throughout the document and have my macro for the header
read them and act accordingly (like skip the header at all, change a
color, etc).

As a basis for this I established the following pattern in an iolated
test case:

   \def\setHeaderVar[#1]{
   \doassign[header][myvar=#1]
   \message{setHEADER: '#1'}
   }
   \def\getHeaderVar{\headermyvar}
   \setupheadertexts[\setups{page:header}]
   \startsetups page:header
   HEADER: myvar=\getHeaderVar
   \stopsetups
   \starttext
   \setHeaderVar[initval]
   page: 1
   \page
   \setHeaderVar[a]
   page: 2
   \page
   \setHeaderVar[b]
   page: 3
   \page
   \setHeaderVar[]
   page: 4
   \page
   \setHeaderVar[]
   page: 5
   \stoptext

This works as expected and the header-macro prints the updated value.
But when I put the same pattern in my big environment-file, I can see
the variable being updated with different values (console), but the
header always puts out just the variable's initial value - so the
variable is read but it's updates aren't picked up by the header macro.
Peeking into console, log & tuc didn't raise any idea yet as to what is
going wrong...

Any idea what is happening and how I can fix this?

Any hints on how I can track this down?

Thanks a lot,
Werner Hennrich, Vienna AT
