Re: [NTG-context] [NTG-Context] Problem with \usemodule[graph] and El Capitan (mac OS)

2016-09-01 Thread Alan Braslau 
No, this is a feature, not a bug!

According to the original graph macros, the data files are kept open, and thus 
subsequent reads will pick up successive data sets in a single file. This is 
explicitly stated in the documentation.

A consequence for us in ConTeXt mkiv, where the metapost code is called in 
multiple passes, is that one must explicitly close the data file if one does 
not want this feature. This, too, I documented. So don't break John Hobby's 
code by removing the saved.

Re: [NTG-context] Captions numbering

2016-09-01 Thread Jan Willem Flamma 
Hi Jose Luis,

I eventually solved this by setting up the subsubsection as follows:

\setuphead[subsubsection]
[incrementnumber=no]

This links to a set of test files on the pragma website and maybe of use to 
you: http://context.aanhet.net/download-1.htm

Kind regards,
Jan Willem

[NTG-context] Get "right" numbers using blocks and enumerations

2016-09-01 Thread Mikael P. Sundqvist 
Hi,

I'm trying to use blocks for answers in a text, but cannot get the
numbering to work as I want. I have read about \processblocks at the
wiki (http://wiki.contextgarden.net/Command/processblocks), but I'm
not sure that is my cure. I probably miss something easy...

The problem is probably easiest shown by an example:

%%%
\defineblock[A]
\hideblocks[A]

\defineenumeration[A][
text=A,
prefix=yes,
prefixsegments=chapter,
way=bychapter,
]

\starttext

\chapter{First chapter}

\beginA
\startA
My first answer in the first chapter.
\stopA
\endA

\beginA
\startA
My second answer in the first chapter.
\stopA
\endA


\chapter{Second chapter}

\beginA
\startA
My first answer in the second chapter.
\stopA
\endA

\beginA
\startA
My second answer in the second chapter.
\stopA
\endA

\chapter{Answers}
\useblocks[A]
\stoptext
%%%

I get, in the Answer chapter

A 3.1, A 3.2, A 3.3 and A 3.4.

What I want to have in the answer chapter is

A 1.1, A 1.2, A 2.1 and A 2.2.

(to follow the numbering in the chapters where the blocks were defined).

Is it possible? What have I missed?

Related: Is there a better way to set answers to questions? (Perhaps
not having to write both the \begin... \start... \stop... \end... for
every question?

This is not very satisfactory because it does not work unconditionally.  For

1) I think you look for the high key.

[NTG-context] Figure-text alignment and wrapping text more tightly

2016-09-01 Thread Florian Leupold 
Dear list,

I am interested in placing a figure on the right-hand side of the page and wrap 
text around it, see MWE below. This works mostly nicely. But I have got three 
questions:

1) Is it possible to top-align the figure with the first line of the paragraph 
to its left?

2) Is there a way to reduce the vertical gap between the first and second 
figures?

3) The keyword “low” for \placefigure seems to have an effect. But I don’t know 
why and could not find a reference to that in contextref.pdf. Is this the 
correct way to wrap text “more tightly” below the figure (compare second and 
third figures).

Thanks a lot for your input.

Best regards,
Florian

Re: [NTG-context] [NTG-Context] Problem with \usemodule[graph] and El Capitan (mac OS)

2016-09-01 Thread Louis-solal Giboin 
Dear Taco,
I thank you very much for your time.
It works perfectly and I will emulate these modifications in my other
figures. I have no ideas about the problem, I just figured out that it came
from El Capitan because I updated the OS yesterday, however I also had to
reinstall MacTex, so it may also come from a different version of ConText?

Dear Hans,
I would like to thank you for all your work on Metafun, as it is the tool I
use now exclusively for all my scientific figures.

Best regards,
Louis-Solal

Re: [NTG-context] [NTG-Context] Problem with \usemodule[graph] and El Capitan (mac OS)

2016-09-01 Thread Taco Hoekwater 
Hi,

I am on El Capitan as well (10.11.6).

ConTeXt  ver: 2016.08.29 22:53 MKIV beta

Attached is an altered input file that works for me. No idea how much of the 
problem
is actually related to El Capitan, but:

* \usemodule[graph] defines a special MP instance called ‘graph’. You need to 
  use that because otherwise the metapost graph macros will not load (that is 
why
  I added the “graph::” prefix twice)

* Something is wrong with the file closing, so I added an extra definition for 
  'graph_close_file' (no idea why it does not work out of the box. Sorry to you 
and Hans).

Best wishes,
Taco

Dear all,
I have updated my OS to El Capitan, and all my scripts including MPgraph

Would someone know how to get rid of this issue?
I thank you very much.

a short code sample:

x:=u*1cm;

a1:=6;

a2:=5;

hauteury:=a1*y;

echelleMEP:=1/10*hauteury/a2;


gdata("explexpl.d",s,

y1:= scantokens(s1);

y2:= scantokens(s2);

draw (7.5*x, y1*echelleMEP)--(8.5*x, y2*echelleMEP) withcolor 0.6 white;

);


incomplete ... how is this called ... what is explexl.d

Re: [NTG-context] \vfill shifts content off grid

Dear list,

when I use a body font size other than the standard, issuing \vfill will move 
the content off the grid.  MWE is below.  How do I fix this?


that's how vfill works, you can try \vskip30\lineheight with a value you 
like



Cheers, Henri
