Hans,

many thanks for your fast fix.

After the newer beta I get another bug:

  $ mtxrunjit --generate
  ~/ctxbeta/tex/texmf-linux/bin/mtxrun:633: attempt to index local
'searchers' (a nil value)

Many thanks for your help,

Pablo

Many thanks for the explanation and for the fix, Hans.

Beta from 2017.08.03 11:02 works perfectly fine with the two texts I
checked.

Many thanks for your help,

no, it's more that i always have a newer luatex so older stuff has to be

Hans,

since it seems you don’t reproduce the bug, I wonder whether this might
be caused by Linux 32bit luatex binaries being version 1.0.5 and Windows
64bt has version 1.0.6.x.

Just in case it helps,

Pablo

Sorry for the noise, Luigi.

I have corrected the variable (as described in
https://mailman.ntg.nl/pipermail/ntg-context/2016/086761.html) and it
works fine.

Hi Joseph,

sorry for overlooking your message.

Of course, you are right. (I cannot code, but defining a local variable
in line 233 and using it with an underscore in line 238 doesn’t make
sense even to me.)

I’m afraid that the typo is present in the newer beta from today

experimental is, well, experimental, so not trunk and not even a tag

But you can easily compile it from svn, it's a matter of
./build.sh --parallel --jit

Hi Akira,

it seems that luatex-0.98.4 has been released for Windows today.

I will wait for the release in the Linux 32bit platform.

Luigi, would it be possible that all platforms have the latest LuaTeX
version included?

find_tail should be findtail I think.

BTW this new rangedimension function is helpful.

Re: [NTG-context] bug in latest beta?

2015-06-01 Thread Otared Kavian 
Hi Pablo,

Indeed the document I was talking about has been typeset with various versions 
of mkiv, but now I observe that sometimes the pagebreaks are made in a very 
strange way. Since I can’t make a minimal example, I put on the following link 
an excerpt of the PDF document where the bad pagebreaks can be seen: 

https://dl.dropboxusercontent.com/u/4316076/bad-pagebreak.pdf

(Please see pages 19 and 32). It seems that this happens, sometimes, but as far 
as I can say from my experiments the bad pagebreak happens always before a « 
proclaim » which is defined as follows:

\defineenumeration[proclaim]
[text=,
before={\blank\startbackground[frame=off,leftframe=on,
rulethickness=2pt,framecolor=darkred,
background=color,
backgroundcolor=screen]},
after={\stopbackground\blank},
style=slanted,
title=yes,
titleleft=,
titleright={.},
alternative=hanging,
width=fit,
right={~},
way=bysection,
prefix=yes,
prefixsegments={chapter:section}]

Actually I found a workaround for this by changing the above definition into:

\defineenumeration[proclaim]
[text=,
before={\blank\startmarginrule[rulethickness=1pt,rulecolor=darkred]},
after={\stopmarginrule},
style=slanted,
title=yes,
titleleft=,
titleright={.},
alternative=hanging,
width=fit,
right={~},
way=bysection,
prefix=yes,
prefixsegments={chapter:section}]

However it would be better to understand why the first definition does not work 
properly, in a rather random way.

Best regards: OK

Hi Otared,

having only three theorems my guess will be probably wrong, but I’ll try it.

The theorem that doesn’t cause a wrong pagebreak is preceeded by a
single line paragraph.

In order to confirm whether this is the pattern, I would remove some
words from the last paragraph on page 19, so that there has only one
line. And I would add some words to the pagraph before theorem 2.3.2 on
page 31, so this pargraph contains two lines.

Could you check this?

Hi Pablo,

Actually I have done what you suggest by adding or removing text, but at the 
end when the document changes all of a sudden the bad pagebreaks appear or 
disappear.
The second definition of « proclaim » I sent you suppresses the bad pagebreaks, 
but in some other situations still I have other bad pagebreaks… Until I have 
not made a rela minimal example the problem cannot be understood and 
permanently solved.

It seems that different MkIV betas may give different results.

I noticed it by compiling the same source with different MkIV betas.

Re: [NTG-context] Bug in latest beta: behavior of \text in StepCharts

 It seems that with the latest beta there is a bug in the way how the
 command \text is handled in step charts (plesae see the attached
 PDF). This bug is absent from mkii, and absent from previous versions
 of mkiv (up to a weak ago, I believe).
 
 This is a minimal example which shows that the font used in each cell
 of \text changes randomly (there are four instances of \text, and
 each time a different font is used…):
 
  begin random-text-size.tex
 \usemodule[steps]
 
 \starttext
 \input knuth.tex
 
 \placefigure[none][-]{}{
 \startSTEPtable 
     \cell {$(f\circ u)(x_{*} + o(1)) = $} \text{definition of
 $f\circ u$} \cell {$f\left(u\left(x_{*} + o(1)\right)\right) = $}
 \text {$u$ is continuous} \cell {$f\left(u(x_{*}) + o(1)\right) = $}
 \text {$f$ is continuous} \cell {$f\left(u(x_{*})\right) + o(1) =$}
 \text {definition of $f\circ u$} \cell {$(f\circ u)(x_{*}) + o(1)$.} 
 \stopSTEPtable}
 
 \stoptext
  begin random-text-size.tex

This bug arises from low-level changes in the handling text from
MetaPost. I have reported this to Hans (in the context of graphs),
although I have not understood how to fix it.

The result is kind of fun: like something that many people produced at
the time of the introduction of the Apple MacIntosh!

Many thanks for the fix, Hans. It works fine now.

BTW, may I remind you of this already reported bug:
http://www.ntg.nl/pipermail/ntg-context/2014/077280.html?

Many thanks for your help,


Pablo

Hans,

I’m afraid that the latest beta contains a bug that prevents the
compilation of any document.

Error is the following (complete log available at
http://www.ousia.tk/nocache.log):

Ouch---my internal constants have been clobbered! ---case 1
mtx-context | fatal error: return code: 1

Could you fix it?


hm, weird, works here ... anyway, i added some extra safeguards, so 
check the next beta

 Page break is wrong if \section is enabled (or I am missing something

 I guess it might be worth fixing it also for ConTeXt in TeX Live 2014.

 Many thanks for your help,
 
 It has to do with trying to improve the 'keep together' successive 
 head/text 'without deadlock' issue; I'll try to improve that bit but for 
 a while it will be somewhat experimental (it's one of the things I'm 
 trying to improve).

Many thanks for the fix, Hans.

I have another wrong page break, but I’m afraid I need some time to
elaborate the sample.

Many thanks again for your help,

 I cannot compile the following sample with latest beta:

 This worked fine with previous beta. Isn’t it a bug?

You have to load a math font because the bullets for the items are taken by 
default from the math font.

BTW: When you have a font related bug check first if it happens also with 
\definetypeface.

\definetypeface[mainface][rm][serif][pagella][default]
\definetypeface[mainface][mm][math] [pagella][default] % comment to get the 
error

\setupbodyfont[mainface]

\starttext

It compiles then, but the first section is moved to the second column, which is 
not the intention.

Fixed (a definition order issue).

The prime handling is somewhat weird as it does some look ahead for 
superscripts (1) because there can b emultiple primes and (2) because 
traditional tex fonts have large prime that needs to be superscripts. 
The current setup works ok with proper opentype math fonts as well as 
virtual lm (which has the big prime). Multiple primes are collapsed onto 
\doubleprime and \tripleprime.
