Re: [NTG-context] two questions on ConTeXt terminology
Hi Pablo, Like I mentioned it depends of the paradigm one uses or to be more expressive: the meta level of discussion. To All: please excuse the use of buzz words in the following. The start/stop mechanism has a different semio-syntactic usage depending on the context (not ConTeXt) it is used in. It can be used for : 1) do command 2) usage of format or element 3) set a variable as in start/stopbuffer This different semantic usage is somewhat unfortunate, but has the advantage of keeping the instruction set(syntax) of ConTeXt simple! The best nomenclature would be entity, but that is not easy to understand for the average joe and jane. On the other side the start/stop mechanism can be seen, in terms of OO, a method that is applied to a object that is passed to. This method is dynamic in that it calls other methods depending of the type of object passed. So we are in the middle of the dynamic OO-programming. If you wish it is a method that is overloaded. Note to Hans, Wolfgang, et al: I realize that it is not implemented as above, but it does reflect the basic concept, to my knowledge and its usage in ConTeXt. Start/stop is a mechanism that is applied to an element, object, entity. Depending on the Enity used with it the semantics of the mechanism is different. So it boils down to the fact what kind of audience you are addressing and what level of knowledge you expect them to have! If you care to discuss this topic more in depth we can go off list. regards Keith Am 03.02.2014 um 20:35 schrieb Pablo Rodriguez oi...@gmx.es: Hi Keith, many thanks for your explanation.

As the name indicates it means start/stop doing 'something' ! This something can be either equivalent to Command or Enviroment in LaTeX. e.g: \startbuffer ... \stopbuffer starts storing things in a buffer(aka. Variable). This would be simailar to command as you can access the buffer with \getbuffer and \putbuffer. Of course one could argue that it is actually like an LaTeX environment that has a side effect of setting a variable for later use. On the other side you have \starttable \stoptable which one would put in the realm of LaTeX-environments. One can practically, use the start/stop mechanism almost anything you define. Depending on the paradigm that you use structure (and/or) element would be appropriate! That is is a program source the definition of a function/procedure/method is a structure/element of the program. Structure element is not necessarily reserved for data structures!! Just my two cents worth.

[NTG-context] Columns and clubpenalty problem
Hi,
with the recent Betas, and the Current, I have a problem with columns and
clubpenalty. In the following minimal the long item (item 1) will introduce
a column break (instead of a simple line break):
\def \defaultclubpenalty{\plustenthousand}
\starttext
\startitemize [columns]
\item This is just a long line and should stay in the left column.
\dorecurse{10}{\item bla bla bla}
\stopitemize
\stoptext
Older ConTeXt versions work as expected (no column break in item 1), for
example
Beta 2013.11.13 12:28 or Current 2013.05.28 00:36.

[NTG-context] draw random branched hydrocarbons
I wrote this code to randomly draw organic branched structures.
Since the organic structures have different dimensions I'm using the scale
function to normalize the width.
The result is a rather ugly because the structures are displayed with fonts
with different sizes.
Is there a way to normalize the structures width only when it exceeds a
certain size?
Thanks a lot

[NTG-context] another question on simplefonts
Hi Wolfgang,
I have the following code:
\definefontfeature[fakeslanted][slant=.25]
\definefontfamily[mainface][serif][TeX Gyre Pagella][slantedfont={*
Regular},sl=features:fakeslanted]
\setupbodyfont[mainface]
\starttext
This is {\em slanted}.
\stoptext
But I don’t know how to define slantedfont={* Regular} with the new
syntax. sl=style:tf or sl=style:regular don’t work (the italic font
is the slanted one).
Which is the right way to do it in the new version of simplefonts?
BTW, I think I should update the simplefonts article in the wiki to add
the new syntax.
After reading the font-sel.mkvi file, I have two questions:
Which are the option keys that come before a colon? I mean, taking
tf=style:bf as a sample, they would be style, file, features? Which ones
am I missing?
How about a new range preset for Hebrew?
Many thanks for your help,
Pablo

[NTG-context] Problem with matematics (derivative and brackets combinations) + wrong pagenumbering

I type some math now. When I use the symbol derivative in combination

Re: [NTG-context] Problem with matematics (derivative and brackets combinations) + wrong pagenumbering
Hello Jannik.
Thanx. I know about ^\prime but this is the same as ^{'}.
In this case is derivative symbol too higher - but emergency it can of
course use.
Use ^{'} or ^{\ prime} in LaTeX leads to equally poor results (too
higher).
Apparently to terms with the fact that it simply will not probably be
better :-) ...
In addition, I noticed that the broken line is too short (and it needs
to be extended with spaces.).

[NTG-context] A default editor for ConTeXt standalone?
Hi all, just a thought. Some time ago wise people decided to include TeXworks into TeXlive, so that newbies installing TeXlive can get a batteries-included package (not having to choose/install an editor). Would it be (a) reasonable and (b) not too much time-consuming to do a similar move with ConTeXt standalone? I'm not saying it would have to be TeXworks (or my beloved Emacs, for that matter;)). I am aware that this is an additional work to maintain etc., and I'm probably not capable of doing it myself, but...
