[NTG-context] resetting setuphyphenatedurl...

2021-10-22 Thread Rik Kabel via ntg-context 

Hello List,

As demonstrated in the following example, it does not seem possible to 
reset \setuphyphenatedurlbefore, after, or normal once changed from 
default. That is, the first change appears to be global and unchangeable.


If this is the case, can someone suggest a workaround?

(Use case: I want to break URLs at any place in a bibliography but have 
additional URLs in text that follows which should be broken only in more 
standard places.)


   \starttext
   \hsize 6em

   Default: \hyphenatedurl{https://wiki.contextgarden.net/URL}

   \blank

   \bgroup
   
\sethyphenatedurlnormal{:=?&/.0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ}
   
\sethyphenatedurlbefore{:=?&/.0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ}
   
\sethyphenatedurlafter{:=?&/.0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ}

I checked the backend code and some of the related os functions. I put
together a patch that hopefully fixes some stuff and doesn't break
anything. The changes:

1) Dates parsed by ConTeXt (function converters.totime), such as those
that are input to backend.date, now allow specifying seconds and time
zone information. If there is no timezone the datetime is presumed to be
in local time, otherwise the datetime is offset by the local / specified
time zone difference (because ConTeXt outputs these dates as local times
with local timezone). Additionally both "T" and " " are now allowed as
date/time separator characters. Thus dates output by ConTeXt can be also
fed in.


i made the parser a bit more tolerant

"1234-12-30"
"1234/12/30"
"1234-12-30 23:45"
"1234-12-30 23:45:16"
"1234-12-30  23:45:16"
"1234-12-30T23:45:16+01:00"
"1234-12-30 23:45:16-02:00"
"1234-12-30 23:45:16+05:00"
"1234-12-30 23:45:16 05:00"
"1234-12-30  23:45:16  05:00"

(I'll send you the file to check/test)


2) Fix the os.timezone function. Previously, it could be wrong around
midnight, which I discovered only by chance. The trick is lifted from
http://lua-users.org/wiki/TimeZone, which I hope is OK. The before and
after (I am at +02:00):

 os.localtime()  2021-10-22 01:44:24
 os.now()2021-10-21 23:44:24
 os.timezone(true)   -22:00


 os.localtime()  2021-10-22 01:46:23
 os.now()2021-10-21 23:46:23
 os.timezone(true)   +02:00


shouldn't we also offer a -02:00 ? (relative)


I also extended the interface of os.timezone to accommodate 1), but as
this is probably a very public interface, I am not sure if these changes
are OK. If more changes to the interface can be made, I propose to get
rid of the delta parameter, since it seems like a remnant from the past.


maybe later, i need to check other files


Some caching can also be introduced, but I again wasn't sure if this
even would be the final form of the function, so didn't do anything in
that sense, yet.


i'll adapt it to that


3) Don't use %X in time formats. It is specified to be platform
dependent and we want %H:%M:%S everywhere. Also, it would be nice if
lpdf-xmp.lmt would use the os.fulltime() function to format dates (like
back-exp.lmt does), but there are multiple dates with different formats
and purposes and it is probably too late to change now.


(probably not that harmfull on the platforms we support)

the reason for different times is that i never liked the timezone in 
regular date/time (so only the mandate one had it) but in the end i 
don't care that much about times/date i never look at (i admit that i 
never consult any of this pdf meta data)



4) I changed the os.fulltime function, that returns date + time + local
time zone to output the _local_ time instead of UTC time. This is AFAICT
the right way to do times. The PDF spec says:

 If no UT information is specified, the relationship of the specified
 time to UT shall be considered to be GMT. Regardless of whether the
 time zone is specified, the rest of the date shall be specified in
 local time.

 EXAMPLE: For example, December 23, 1998, at 7:52 PM, U.S. Pacific
 Standard Time, is represented by the string D:199812231952-08'00

Apparently, almfixed and kurier fonts no longer load as before.

But in this way yes, and I still can't find the reason:

\setupbodyfont [FAR,10pt]

Hi Michal,

I haven’t found the time to check this, but this is pretty much what I
wanted: being able to set other timezones than the local one.

Many thanks for your help,

Re: [NTG-context] some ConTeXt distribution's Fonts don't work

2021-10-22 Thread a badin via ntg-context 
double-checking the fonts, two still don't switch. this example
procudes a pdf with Latin Modern instead ALM Fixed and Kurier. Any
ideas on how to use those?

\starttext

Luis, the folder you've mentioned does not contain anything that would
resemble Almfixed. Kurier does not have a .lfg file there - perhaps
these are hints at a solution, but I don't know.

[NTG-context] vertical align in combination

2021-10-22 Thread Pablo Rodriguez via ntg-context 
Dear list,

I have the following sample:

  \starttext
  \setupexternalfigure[location=default]
  \startcombination[nx=3, ny=2, location={middle}]
  {\externalfigure[mill.png][width=.25\textwidth]}
  {\externalfigure[cow.pdf][width=.25\textwidth]}
  {\externalfigure[cow.pdf][width=.25\textwidth]}
  {\externalfigure[spider.eps][width=.25\textwidth]}
  {\externalfigure[hacker.png][width=.25\textwidth]}
  {\externalfigure[mill.png][width=.25\textwidth]}
  \stopcombination
  \stoptext

The first line has the images vertically centered, but the second line
has them aligned to the top. Using "align=middle" made no difference.

How could I get all lines with images vertically centered?

Many thanks for your help,

Pablo

Hans,

many thanks for your reply and your sample.

A more visual version for me would be:

  \setupbodyfont[sans, 30pt]
  \setuppagenumbering[location=,]
  \showframe

  \starttext
   \topskip4cm
  \dostepwiserecurse{0}{360}{10}{
  \doloopoverlist{normal,default,depth,fit,broad,high,middle}{
  \ruledhbox{\rotate[rotation=\recurselevel, location=\recursestring]{%
  \framed
 [width=\textheight, height=\textwidth, rulethickness=5pt,
  depth=0cm, foregroundstyle=\bfd]
{\recursestring, \recurselevel°}
  }
  }
  }
  }
  \stoptext

I have just added it to
https://wiki.contextgarden.net/Scaling_Rotating_Mirroring_Clipping#Rotating_Figures.

Many thanks for your help,

\setupcolors[cmyk=no,rgb=yes]
\starttext
\externalfigure[icon-newsletter][conversion=mp]
\stoptext

renders black eyes. Without cmyk=no it renders fine. 

Anything explanation to add to the wiki? Or is it a bug?

We hit a limti in lpeg that allocates memory by duplicating the size 
which then hits a top and falls back in allocating by + 1 every capture 
which then kind of stalls the xml interpretation. I can hack that to 
work (and need to check that with every lpeg update), but as we enter a 
next stage in th econversion mem starts going virtual anyway and I see 
my SSD being tortured so I aborted. More testing has to wait till I (if 
ever) have a faster machine, with (say) 64GB super fast memory.


On my machine the still ok size is some 200MB.

an extra vertical space before.

Hi,

I cleaned up some more backend code.  There were some mails about dates
and such and although the date field in setupinteraction works ok a more
drastic overload is doen with directives. The reason is that the fact
that we can set the date (and traler) is only because it permits
generating pdf files that can be compared. No date as a bad idea anyway.

\setupinteraction[title=My Title]
% \enabledirectives[backend.date=2034-06-07]


Many thanks for the new version, Hans.

Is there a way to add time and timezone in backend.date?


Pablo : transparencies should work again (wrong alias fixed).


Many thanks for this fix too.

Sorry for insisting, but could you check what is wrong with an extra
blank space in rotated imposition
(https://mailman.ntg.nl/pipermail/ntg-context/2021/103909.html)?

.. it was not really a minimal example ...

\showframe

\starttext
\topskip4cm
\rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\page


\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\page
\rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\page


\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\page
\stoptext

so, you need to wrap it, like

\startpagemakeup \rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\stoppagemakeup
\startpagemakeup 
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\stoppagemakeup
\startpagemakeup \rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\stoppagemakeup
\startpagemakeup 
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\stoppagemakeup


and not make it 'sort of text that breaks or not across the page'. Now 
it is an interesting question why ... (spoiler: nice animation:)


\starttext
\topskip4cm
\dostepwiserecurse{0}{360}{1}{

\rotate[rotation=#1]{\externalfigure[A3page.pdf][page=1,width=\textheight]}
}
\stoptext

so we probably cross some threshold with some angles and because these 
are basically lines, we then get an interplay woth topskip, maxdepth etc 
(which normally goes unnoticed)


the good news is that you can play with it because rotate is normally 
configured for inline usage (so we get depth and height) you can use the 
location parameter to do otherwise:


% normal default depth fit broad high middle

\starttext
\topskip4cm
\dostepwiserecurse{0}{360}{1}{

\ruledhbox{\rotate[rotation=#1,location=high]{\externalfigure[A3page.pdf][page=1,width=\textheight]}}
}
\stoptext

irr it's actually shown somewhere in a manual but the source also has this

% \dostepwiserecurse{0}{360}{10}
%   {\startlinecorrection[blank]

so, not a bug but a features (that code hasn't been touched for ages, 
apart from maybe some lmtx interface adaptation), and if it's not in the 
wiki .. you know what to do now

Hi all,
I suppose this is a bug or something unresolved, the following code
renders a pdf in LMRoman (lmserif) only:

\starttext
\startitemize[none]
\switchtobodyfont[antykwatorunska] \item font-test 123
\switchtobodyfont[kurier] \item font-test 123

\switchtobodyfont[neoeuler] \item font-test 123
\switchtobodyfont[stixtwotext] \item font-test 123
\stopitemize
\stoptext

How to switch to these fonts? Could this be fixed by default? I'm on
ConTeXt  ver: 2021.10.21 19:57 LMTX.
I've tested all the fonts from
https://wiki.contextgarden.net/ConTeXt_distribution%27s_Fonts
 and
these are the only one that do not work.

Kind regards and thanks for the great work on context, I just updated
and was able to run my previous code resulting in a slightly smaller
pdf, which I find great!
Andrej

also, some are ss or tt

\starttext
\startitemize[none]

It works very nicely. I played with the test file you sent me, and I
find that in the .lfg file, the up parameter set to 0.06 instead of
0.1 looks better to me.
there are no ssty's for the quadruple prime in that font but if you need 
primes so badly you probably shouldn't use it anyway i guess (there are 
only super-textsize ssty variants for the 1/2/3 and their reverse)


anyway, as you desperately need these quads (why check otherwise), 
adding this to the lfg blob helps:


local four = characters[0x2057]
if four then
local one = characters[okay]
local owd = .75*one.width
local off = .6*one.height
four.width = 4*owd
four.commands = {
{ "offset", 0, off, okay },
{ "offset",   owd, off, okay },
{ "offset", 2*owd, off, okay },
{ "offset", 3*owd, off, okay },
}
else
-- we don't add (but we could), just patch, and there's no
-- reverse quad either
end

and no one will notice (unless you wikify al this)

Which one exactly? 

Both https://lists.contextgarden.net/ and https://mailman.ntg.nl/ seem fine to
