[NTG-context] registers: setting pageleft parameter by index term

2019-04-29 Thread mf

Hello list, please consider this MWE:

\definenumber[p]
\setnumber[p][1]
\def\PageLeft{ p.~}
\def\TextCommand#1{\getnumber[p] 
#1\doif{\rawcountervalue[p]}{2}{\def\PageLeft{ P.~}}\incrementnumber[p]}

\setupindex[n=1,pageleft=\PageLeft,pageright=,textcommand=\TextCommand]
\starttext
Foo\index{foo}.
\page
Bar\index{bar}.
\page
Baz\index{baz}.
\page
\placeindex
\stoptext

The pageleft parameter of \setupindex (\setupregister) is normally set 
to " p.~", but it gets redefined to " P.~" for the second term in the 
index ("baz").


Here i'm using a counter and i check when it is 2, but i'd like to check 
if the term is "baz" (and i don't know how to do that test).


If you use deeptextcommand instead of textcommand, the pageleft 
parameter can't be redefined.


The following variation compiles, but it does not work, because pageleft 
is always " p.~":


\definenumber[p]
\setnumber[p][1]
\def\PageLeft{ p.~}
\def\TextCommand#1{\getnumber[p] 
#1\doif{\rawcountervalue[p]}{2}{\def\PageLeft{ P.~}}\incrementnumber[p]}

\setupindex[n=1,pageleft=\PageLeft,pageright=,deeptextcommand=\TextCommand]
\starttext
Foo\index{foo}.
\page
Bar\index{bar}.
\page
Baz\index{baz}.
\page
\placeindex
\stoptext

In my setup i must use deeptextcommand, and i want to set the pageleft 
and pageright parameters to a different value for some particular terms 
of the index.


Since the argument passed to deeptextcommand is not the text of the term 
(it's actually an id used to retrieve a much longer text), i can 
discriminate the terms by their id, but i can't setup pageleft and 
pageright accordingly from the command specified by deeptextcommand.


On the other hand, textcommand would let me set pageleft and pageright, 
but its argument is not pure text, and i don't know how to get the id 
from it.


How can i solve this problem?

Thanks,

Massimiliano

[NTG-context] Lua os.date() localization in context

2019-04-29 Thread Romain Diss
Hi all,

I would like to print the day name of a date in french using my current
locale.

In lua I can do:
> os.setlocale('fr_FR.UTF-8',all)
> print(os.date("%A"))

But in a cld document it doesn't work. Context complains about using
"os.locale in a supposedly locale neutral enviroment" and it prints the
day name in english.

How can I translate the day names without hardcoding everything?

Thanks in advance.

Best.

Perhaps. Or generated by older software. Though my GraphicsMagick (1.3.28):
"gm identify input.png" doesn't tell me anything about a "CRC error":
input.png PNG 334x168+0+0 DirectClass 8-bit 29.6Ki 0.000u 0m:0.03s

Anyway, at the beginning of a new book there are 10 of such images with 
artefacts.
I can handle the problem by converting them to .tiff-pictures. As long as I 
shall
have enough storage in my host :-), for me all will be ok.

Thank you!

[NTG-context] PDF output routine in lmtx

2019-04-29 Thread Christian Prim
Hi

in lmtx the pdf output routine has changed afaik. I just wanted to report,
that in lmtx our printer/copier (Ricoh 8200S or Ricoh 8110S) doesn't print
any character. A standard document as the MWE prints well under mkiv. Under
lmtx, there is no output (blank sheet). In a document with a tikz-figure,
the tikz-figure (without labels, as they are text) is printed. Something
with text output must have changed, that makes it incompatible with the
copier at our school. I tried to print with different drivers and also used
the printers interface (direct print via usb-stick). No success. Are they
some flags I can play with (like other pdf-version or so) to find a
solution to this problem? This "bug" prevents me to use lmtx at out school.

Interesting news!
After having changed the png-Format of the external figure to ".tiff"-Format by
