I am sorry. You are, of course, correct, and I use both, so should know 
better.

That is simply not true!  Content inside ConTeXt buffers is as verbatim
as reading an external file.  Try \typebuffer instead of \getbuffer

The bibtex entry in this example is provided in a buffer. The buffer 
mechanism does not handle characters any differently than other text in 
the file, and % in a ConTeXt buffer has to be escaped if it does not 
signify a comment. If you specify an external (.bib or .bibtex) file to 
supply the data,  % does not need to be escaped. So, this part is simple 
user error.


(With

   \starttext
   \startbuffer
  abc%def

  ghi\%jkl
   \stopbuffer
   \getbuffer
   \stoptext

you do not get %def in the output. Why do you expect different behavior 
if the buffer holds a bibtex entry?)


The way hyphenatedurl handles things may well be worthy of improvement.

From BibTeXing:

7. For Scribe compatibility, the database files allow an @COMMENT
command; it’s not really needed because BibTEX allows in the database
files any comment that’s not within an entry. If you want to comment
out an entry, simply remove the ‘@’ character preceding the entry type.

...

14. LATEX’s comment character ‘%’ is not a comment character in the
database files.




From Tame the BeaST:

New entries always start with @. Anything outside the “argument” of a
“command” starting with an @ is considered as a comment. This gives an
easy way to comment a given entry: just remove the initial @. As usual
when a language allows comments, don’t hesitate to use them so that you
have a clean, ordered, and easy-to-maintain database. Conversely,
anything starting with an @ is considered as being a new entry.

There is a special entry type named @comment. The main use of such an
entry type is to comment a large part of the bibliography easily, since
anything outside an entry is already a comment, and commenting out one
entry may be achieved by just removing its initial @.


So bibtex has a funny way of dealing with comments, and do we really
care about Scribe? We made the choice NOT to remain *strictly* bibtex
compatible, after all bibtex is limited to ASCII 7-bit!

The % comment is *universal* in TeX, Metapost, etc. so we chose to
respect this, much stronger in my opinion, convention.

That is easily fixed by making \hyphenatedurl aware of \% being
\letterpercent.


\appendtoks
  \let\%\letterpercent
\to \everyhyphenatedurl


However, I wonder whether the treatment of % in bib files is correct,
as regular BibTeX does treat the % verbatim.  Because the following
LaTeX example works just fine, with unescaped %.  In my opinion this
behaviour should be adopted by ConTeXt.

So far as I can tell, the problem comes with the specification of the

Re: [NTG-context] BUG: % is comment in btx fields

Of course, you have to escape the percent character if you do not want
it to be interpreted as a comment... however, in the example below, the
URL does not get rendered properly, nor does using \letterpercent, so
there is something that we need to fix in our treatment of URLs.

\startbuffer[references]

  author = "Kraft, Nathan",
  title = "Mr Kraft's Virtual Filing Cabinet",
  year = "2015",

[NTG-context] get the dimensions of xcell

sorry for bothering you with this minor question, but this information

I have the following sample:

\starttext
\startxtable[option=stretch]
\startxrow
\startxcell \the\lineheight\stopxcell
\startxcell how do I get the frame height?\stopxcell
\stopxrow
\startxrow
\startxcell \the\textwidth\stopxcell
\startxcell how do I get the frame width?\stopxcell
\stopxrow
\stopxtable
\stoptext

How can I get the height and the width of the xcell?

I mean, is there a similar command for xcells or frames?

Many thannks in advance,

[NTG-context] Fwd: ANNOUNCE: pandoc scholar

2017-05-08 Thread Idris Samawi Hamid ادريس سماوي حامد 

Dear gang,

This just in. Slightly off-topic, but in the wake of the recent markdown  
thread some of you may find this approach interesting or a source of ideas  
for doing something similar in ConTeXt.


Best wishes
Idris

--- Forwarded message ---

Subject: ANNOUNCE: pandoc scholar
Date: Mon, 08 May 2017 11:43:42 -0600

I'm happy to announce pandoc scholar, a tool and general effort to
enable and promote the use of pandoc markdown as a format for scientific
publishing .

We developed conventions, lua scripts, and accompanying makefiles to
make authoring of scientific articles as simple and comfortable as
possible, enabling authors to semantically enrich their manuscripts with
additional metadata. The corresponding manuscript has been published
today in PeerJ CS: .

The pandoc scholar utility was build with compatibility in mind,
requiring only `pandoc` and `make`.  Most computations are performed
using lua scripts, using [panlunatic] to output the modified document as
pandoc JSON.  Makefiles are used to hide the additional complexity and
to set sensible default options when calling pandoc.  A styled html
template, which makes use of the additional metadata fields, is provided
as well.

Any feedback is welcome.

[NTG-context] linenumbers in marking

2017-05-08 Thread Thomas A. Schmitz 

Hi all,

5 years ago, on the mailing list, there was a thread started by Pablo 
Rodríguez (http://www.mail-archive.com/ntg-context@ntg.nl/msg62140.html) 
about line numbers in headers. Wolfgang Schuster replied that in 
principle, it's possible to have line numbers in headers, "but it’s not 
usable because the numbers are always shown on the next page." He made 
the following example (which I have slightly adapted):


\definemarking[linenumber]

\define\LinenumberCommand
  {\normalexpanded{\setmarking[linenumber]{\linenumber}}}

\setuplinenumbering[command=\LinenumberCommand]

\startsetups linenumber

\doiftext {
\getmarking[linenumber]
}
{
\getmarking[linenumber][top] – 
\getmarking[linenumber][bottom]

}

\stopsetups

\setupheadertexts[\texsetup{linenumber}]

\starttext

\dorecurse{6}{\input tufte\par}

\startlinenumbering
\dorecurse{20}{\input knuth\par}
\stoplinenumbering

\resetmarking[linenumber]

\dorecurse{6}{\input tufte\par}

\stoptext

Hans wrote: "currently it's not possible but it's no big deal to add 
that feature at some point." I have now a similar problem with markings 
in a header. Is there a solution to this? Could it be implemented now?


Thanks, and best wishes

Thomas
