[NTG-context] Strange page breaks
Hello,
the attached example causes very strange page breaks.
1. The subsubsubject is the last line on the first page. That doesn't
look very nice.
2. The xtable is broken although the whole table fits on that page.
Is there anything I (or you? :-)) can do about these two problems?

Re: [NTG-context] Deleting -temp files

Hi,
context --purgeall deletes all temporary files (i.e., files containing
-temp-). In fact, I had requested this feature so that the filter
module does not clutter the current directory with temporary files.
However, there is a bug. ConTeXt deletes all files containg -temp
(note the missing - at the end). So,
$ touch A1-temperature.tex
$ context --purgeall
gives
mtx-context | purged files: A1-temperature.tex
AFAICS, mtx-context.lua is correct. It contains -temp- as expected.
So, I don't know why files containing -temp are deleted.
hm, shouldn't
local special_runfiles = {
-mpgraph, -mprun, -temp-
}
be:
local special_runfiles = {
%-mpgraph, %-mprun, %-temp%-
}
can you test that?

does the vim module have a feature to specify the input path,

not that strange but it's obscured by the fact that you use a float
(which has different spacing and room-for rules) without caption
in this case you can omit the placefloat and do
\startxtable[header=repeat,split=yes]

Doesn't quite work, since then the header isn't repeated when the
table is actually split.
With natural tables there seems to be a similar problem. But I guess
that enabling split=yes will actually place it inside a float
automatically which leads back to the initial problem.
You can tell context to force a page break when there isn’t enough space for
the heading.

[NTG-context] Refreshing (synchronizing) values between Lua variables and TeX registers
Hello ConTeXist and Lua experts
Is there any way to refresh values between the values stored in Lua
code and TeX registers?
I need to evaluating the values of TeX registers (counters, dimensions,
height of boxes, etc.) during the Lua cycle.
I would like in the cycle read values from the TeX registers and write
back there so that all values were always synchronized.
Or I need advice on how to proceed. Most of my Lua code is in a separate
file in Lua
function.
Is there a universal way to jump out of cycle to TeX synchronize all
values between TeX registers and Lua values (even at the cost of
slowing down) and then go back into the cycle and continue?
I do not write cycles using the TeX macro language, but so far I'm
failing in way around it.
What I need to I knowing or What I need to learn?
Thanx Jaroslav Hajtmar
The minimal example shows (maybe) what I mean:
\newcount\testcount
\def\countrefresh{\directlua{tex.count.testcount = tex.count.testcount + 1}}
\def\universalrefreshcommand{\directlua{-- ???}}
\def\printdebuginfo{
\directlua{tex.sprint(': ',tex.count.testcount, - ,
\\the\\testcount,\\par)}
}
\starttext
Here values are not synchronized:
\testcount=0
\startluacode
local i=0
for i=1,5 do
tex.sprint(i)
tex.count.testcount = tex.count.testcount + 1
tex.sprint(\\printdebuginfo)
end
\stopluacode

sure, as the 'prints' end up in the input buffer and are dealt with
after the lua code has been dealt with; at some point we can have
coroutines for going back and forth
in your case I'm not sure what is the problem as you can set the valus
at the lua end and print the current value when needed

Re: [NTG-context] \box0 to Lua
Hello,
sorry for impoliteness - last two messages should't have been addressed to the
forum, but only to me and Jaroslav - thus in Czech.
The question still lasts...
Best regards,
Lukas
how to call \box0 and \hbox to3cm{abc} by Lua?
\startluacode
context[[\box0]] % OK but a nicer way preferred, so keep on trying -
context.box(0) % Error
context.box{0} % Error
context.box0 % Error
context.hbox({to = cm}, abc) % Error
\stopluacode

[NTG-context] horizontal spacing between only two rows
Hello,
in the following example it is possible to split a table vertical
(between the first and the second column with (\startxcell[distance=5pt]
test \stopxcell).
\starttext
\startxtable[option={stretch,width}]
\startxrow
\startxcell[distance=5pt] test \stopxcell
\startxcelltest \stopxcell
\startxcelltest \stopxcell
\stopxrow
\startxrow
\startxcelltest \stopxcell
\startxcelltest \stopxcell
\startxcelltest \stopxcell
\stopxrow
\startxrow
\startxcelltest \stopxcell
\startxcelltest \stopxcell
\startxcelltest \stopxcell
\stopxrow
\stopxtable
\stoptext
But how can I get horizontal spacing between only two rows, and not
for the whole table?
Thank you,
Helmut

Re: [NTG-context] Is it possible to generate eps files using metafun and context?
On 06/18/2012 04:19 PM, Hans Hagen wrote: and then use pstopdf to turn the pdf into an eps You must mean pdftops, since pstopdf cannot convert pdf files into eps but pdftops can. I tried pdftops, the result quality is high, but since my desire is to provide eps figures to others that have to insert high quality figures into Microsoft Word, the pdftops converted eps files cannot insert into Microsoft Word. Fortunately, I have found out that pstopdf uses ghostscript/Inkscape to do the real job, and I use ghostscript directly to convert pdf into eps, the quality is high enough with the -dNOCACHE option (I had tried inkscape before my last posting a few weeks ago, and the resulting quality is not high enough when I'm using Fedora 16. But it seems that inkscape in Fedora 17 produces better quality now, though ghostscript is better), and it can be recognized by Microsoft Word.

Re: [NTG-context] Input path to include external files with vim module
On Mon, 18 Jun 2012, Marco wrote:
does the vim module have a feature to specify the input path,
similar to \usepath for context files or \setupexternalfigures
[directory=…] for graphics?
Currently, it does not.
I'm looking for a solution not to hard-code paths into my files.
Example:
\usemodule [vim]
\definevimtyping [XML] [syntax=xml]
\starttext
\typeXMLfile{code/foo.xml} % what I do now
%\typeXMLfile{foo.xml} % what is desired
\stoptext
I'll see how easy it is to hook into the code for \usepath etc. It might
be best to add this feature to the filter module, but I'll have to come up
with another key as `directory` is already taken to specify output
directory.

[NTG-context] ConTeXt and SciTE
I'm trying to get the SciTE lexers that come with the ConTeXt distribution working but I'm not having much luck. SciTE certainly processes the ConTeXt start-up script but never does any highlighting. I always get the warning that lpeg is not loaded but I cannot find any separate lpeg.properties file or lpeg.lua file so I don't know how to get it imported and active to run the lexers. Any suggestions? Interestingly, the lexers work just fine in Textadept but I haven't quite figured out how to get them to load automatically. I have to manually select the lexer but it works fine once I do. I'm inclined to go the Textadept route and build a nice snippets file and Adeptsense support but I'd like to see things running in SciTE, too. Right now I'm using Emacs to do my editing but AUCTeX does a poor job of supporting ConTeXt and when I asked about future plans on the AUCTeX mailing list, I got a snarky, sarcastic reply that code doesn't change itself. Typical FSF attitude, I see. If I'm going to have to write my own support, Lua is much closer to the languages I've used before than elisp so it should be considerably easier. Of course, I'll pass on anything I come up with to the ConTeXt community. -- Bill Meahan K8QN The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails. -- William Arthur Ward This message is digitally signed with an X.509 certificate to prove it is from me and has not been altered since it was sent. smime.p7s Description: S/MIME Cryptographic Signature ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

The first argument is the head of a node list, the second can be
the width in sp (or “spread”). See Patrick’s excellent tutorial:
http://wiki.luatex.org/index.php/TeX_without_TeX
to get started with node fun.
(The \boxn registers are accessible as tex.box, see page 112 in
the luatex manual.)
