[NTG-context] typefile behaviour

2010-06-22 Thread Gery Debongnie
Dear ConTeXt list,
I encountered a weird behaviour while using typefile. Here is a
minimal example, to illustrate what I am saying.  We have two files,
test.txt and test.tex, respectively (between the  -).
-
1
2
3

4
5
---
\setuptyping
[before={\startframedtext},
 after={\stopframedtext}]
\starttext
\typefile[start=2,stop=4]{test.txt}
\typefile[start=2,stop=5]{test.txt}
\stoptext
---
Now, if you save those lines into test.txt and test.tex, and if you
compile the tex file, you get the exact same boxes.  As far as I
understand it, ConTeXt works as I expect when there is no empty line,
meaning that it typeset the lines between start and stop. However,
when there is an empty line right after the last line, ConTeXt also
includes it.  I don't really understand that behaviour. Perhaps it is
something to do with different paragraphs, I don't know.

However, what I do know is that it is annoying.  It adds an empty line
at an unwanted place, and it looks unprofessional in my text.  So, my
question is the following :
1. Why does it behave like that? Is that a bug?
2. What should I do to solve that problem?

Regards,

Géry D.

It is in there, but as it goes in reference manuals, you have
to know what to look for. At this moment, there are no tutorials
or something like that about the token interface (mostly because
I am not quite happy with how it works right now).

[NTG-context] \setcharacterspacing[frenchpunctuation] in mkiv

2010-06-22 Thread Otared Kavian
Hi Hans, and all gurus,

I noticed that the mkiv command
\setcharacterspacing[frenchpunctuation] 
influences even the \type environment: is this behavior wanted or is it a side 
effect?
Have a look at the following example in which 
\type{http://wiki.contextgarden.net} results in a space between « http » and « 
:// » as if the \type command were ignored regarding spacing.

Best regards: OK
%%% french-punctuation.tex
\mainlanguage[fr]
\setcharacterspacing[frenchpunctuation]

\setupinteraction
  [state=start,color=darkgreen]

\useURL
[wiki]
[http://wiki.contextgarden.net/]
[]
[{\tt http://wiki.contextgarden.net/}]

\starttext
Here we are following the French rule of typesetting semicolumn: did you see?

However this rule should not be followed in \type{\type}\dots

\from[wiki]
\blank

\useURL{\type{http://wiki.contextgarden.net/Main_Page}}

\blank
\starttyping
http://wiki.contextgarden.net/Main_Page
\stoptyping

\blank
since otherwise the interaction in the latter example is broken. Indeed there 
should not be a space 
between \type{http} and \type{://}.

[NTG-context] Wrong typesetting of "pages" in AMS-style publication list

2010-06-22 Thread Stefan Müller
Hi,

I've encountered an issue with the AMS-style publication list (Mark IV). When 
the  bibliography items in my document are typeset in the publication list, the 
attribute "pages" (from the .bib file; a range of pages is specified, e.g. 
"pages = {12--34}") is sometimes preceded by "p." (e.g. for "@incollection"), 
sometimes by "pp." (which I would think of being correct) and sometimes there 
is nothing (e.g. for "@article"): no "pp."/"p." and not even a point afterwards 
ending the bib item. Is this behaviour intended?

I took a look inside the file "bibl-ams.tex" where (afaik) the setup is 
defined. The calls of \insertpages there differ a lot:

  \insertpages{, p. }{. }{. } %from book, l.203
  \insertpages{\unskip, p.~}{. }{\unskip. } %from incollection, l.306
  \insertpages{\unskip, }{}{} %from article, l.165
  \insertpages{\unskip, \fixpp.~}{. }{\unskip. } %from inproceedings, l.344

It seems to me that the last one actually is what every call should look like. 
But maybe I'm getting this wrong.

Any suggestions and/or explanations appreciated.

Best regards,
Stefan.

Well, when bibl-ams.tex was written, there was no good specification
so I just implemented something based on some fuzzy examples. If you

[NTG-context] [OT][Fwd: Re: Proposal of a new Q&A site centered on Latex]

Hi!

Nearly 20 days ago I proposed the creation of a Q&A site using the
StackExchange engine related to TeX and LaTeX. Now, thanks to the
community that supported it, the proposal is in its commitment phase.
This means that we have more or less defined which questions are
suitable for the site, and which ones are not. At this stage, we are
looking for experts willing to help with the site when it begins its
beta stage (provided we find support enough).

Collaborators willing to commit to this project will have an important
responsibility towards the foundation of the site. In addition,
committing will require some work from your part: participating
actively in the site, visiting at least three times per week, asking
at least three questions during the beta phase, and answering as many
questions as you can for at least three months. I know it can be a
burden, but the point is that it is crucial to gather a critical mass
of committed people that can keep the site up and running. If you want
to join this project now, here is the link:

Okay, I had this problem, too. If I find a reliable and comprehensive 
source for how the AMS-style should look like, I'll try to implement it. 
But currently I am not able to make too much sense out of what I find in 
bibl-ams.tex. Maybe the reason for this is that I'm not much into 
(plain) tex. But anyhow, when I stumble over a specification I'll send 
it to the list.


Thank you,
Stefan.

yourself. Code goes something like this:


Thank you, I'll try.
Seems like I should learn MetaPost finally...


If there isn't - is the transparency of PNG usable?


Sure, and may use less resources than mp drawings, but that is
definitely RGB



Yes, of course. Since I only need to output on a color laser printer,  
it will probably work.

Processing time matters.

[NTG-context] textbackground and protrusion

2010-06-22 Thread Paul Schalck
Hi! Currently (Context beta 2010-06-20 / Luatex 0.60.1), textbackground and 
protrusion don't work together. Here's a little test file:


---

\showframe

\definefontfeature[test][mode=node,script=latn,kern=yes,trep=yes,tlig=yes,protrusion=quality]
\definetextbackground[MyTextbackground][frame=off]

\enableprotruding

\starttext
\definedfont[lmroman12-regular*test]
"An arbitrary and \startMyTextbackground incomplete \stopMyTextbackground\ 
sentence."


\stoptext

---

Is there a workaround for this? Thanks in advance.

[NTG-context] textbackground and protrusion (update)

2010-06-22 Thread Paul Schalck
It seems that the typographical quotation marks got lost in my test file. It 
has thus become pretty much useless. Just enter some other character instead 
to make protrusion visible.
