Further experimentation suggests that the problem is in the interaction

Thank you

\startluacode

the % should be \letterpercent

btw, use locals for numer and denom

you can also do this:

         for i=1,k do
             numer = numer * ( n - i + 1 )
             denom = denom * i
         end
         context("%0.5g",(numer/denom) * p^k * (1-p)^(n-k))
     end
\stopluacode

\starttext
     \ctxlua{document.Binomial(100,60,0.25)}
\stoptext

in general

context("format",)

is a bit more powerful than using format

[NTG-context] structureuservariable in ToC

2018-01-14 Thread Henning Hraban Ramm

Now, my second issue with user variables:

"""
\define[1]\ChapterTocEntry{%
  
\doifnotempty{\structureuservariable{author}}{\structureuservariable{author}\crlf
 }%
  #1%
  
\doifnotempty{\structureuservariable{subtitle}}{\crlf\structureuservariable{subtitle}}}

\setuplist[chapter][textcommand=\ChapterTocEntry]

\starttext
\completelist[chapter][criterium=all]

\startchapter[
  title={The Use of Typefaces}][%

  subtitle={Ein zapfiges Zitat}]

\input zapf

\stopchapter

\startchapter[
  title={Sheep and Goats}][%
  author={Siegfried Tufte},
  subtitle={Tofte Tufte-Zitat}]

\input tufte

\stopchapter

\stoptext
"""

I’m trying to get author and subtitle into the ToC (while in the content, 
subtitle goes to the margin and author to the end of the chapter).
But in this example, both are empty (but not empty enough for doifnotempty), 
while in my actual project I always get author and subtitle from the first 
chapter.
I guess this is an expansion problem?

I use labels displayed as numbers in the margin to serially identify 
quotations in a book about the development of quotation and 
misquotation, at the same time generating reference information for 
cross-referencing. While most quotations are blocks and can be 
handled by enumerations, many are in-line quotations, and enumeration 
cannot be used for these.


The wiki describes enumerations as the MKIV replacement for labels, 
and the documentation as far as I can see omits \definelabel. Unless 
there is something else supported in MKIV that can assume this 
function of labels, can we please have full support for labels? I 
would not want to see labels deprecated before the functionality is 
reproduced.


(Of course, if you can suggest how enumeration can be adapted to this 
requirement, or suggest an alternative mechanism, this request can be 
rejected.)


two options:

\defineconstructionalternative

    \stopchapter

\stoptext


I played a bit more with enumerations and resolved one issue, I think. 
The forced paragraph break is a feature of the default before/after keys 
(both of which I need to null). Once this is done, enumerations can be 
used for in-line text as well, and when an explicit \par is added to 
\footnotes, the enumeration index appears there, unlike labels, where it 
does not appear.


Can you explain why the enumeration defined with constructionalternative 
rendering fails in footnotes, as shown in the following example? I 
suspect it has to do with my not understanding the use of 
\flushconstructionheadbox.


   \defineconstructionalternative
  [mylabel]
  [renderingsetup=constructionrenderings:mylabel,
   width=]

   \startsetups[constructionrenderings:mylabel]

    display=no,  % suppresses line

    before=, % no added text before

Could you explain the display key. The best I could determine from 
strc-con.mkvi is that if it is not 'no' in a construction, a \par is 
inserted, although I do not see why it is required in one case, and the 
other in my example above.


Could you also explain why \par is required in the footnotes when it 
does not seem to be needed in

[NTG-context] uservariables in heads and lists

2018-01-14 Thread Henning Hraban Ramm

Hi, it’s been a while...

For a scientific magazine I need subtitles in the margin and authors as well as 
subtitles in my ToC. I didn’t yet try the latter, since I got stuck with the 
first.

Here’s my complete, not really working example:

"""
\usemodule[visual]
\setuplayout[
backspace=21mm,
topspace=12mm,
width=117mm,
height=270mm,
header=15mm,
headerdistance=2mm,
footer=3mm,
footerdistance=4mm,
rightmargindistance=5mm,
rightmargin=55mm,
leftmargin=0mm,
grid=yes,
location=doublesided
]

\define[2]\ChapterCmd{%
  {\bfa #2}
  {\inouter{\structureuservariable{subtitle}}}
}
\setuphead[chapter][
page=right,
command=\ChapterCmd,
]

\starttext
%\showlayout

\starttitle[title={Content}][subtitle={}]
%\placelist[chapter][criterium=all]
\stoptitle

\startchapter
  [title=My Title,][% is this necessary?
  subtitle=My Subtitle,
  author=Me and I]

\fakewords{100}{200}
\stopchapter

\stoptext
"""

Problems:
(1) The subtitle is not in the margin as defined by \setuplayout, but beside 
the chapter title.

(2) \starttitle throws 
...xmf/tex/texmf-context/tex/context/base/mkiv/node-nut.lua:823: table index is 
nil
stack traceback:
...xmf/tex/texmf-context/tex/context/base/mkiv/node-nut.lua:823: in

function <...xmf/tex/texmf-context/tex/context/base/mkiv/typo-mar.lua:204>

What does that mean?

[NTG-context] Problem with string.format (Lua)

2018-01-14 Thread Fabrice Couvreur

Hello,
I start with Lua and I try to display my result with 4 decimal places
without success.
Thank you
Fabrice

\startluacode
function Binomial(n,k,p)
if k > n then return nil end
if k > n/2 then k = n - k end

numer, denom = 1, 1
for i = 1, k do
numer = numer * ( n - i + 1 )
denom = denom * i
end
return (numer/denom) * p^k * (1-p)^(n-k)
end

\stopluacode

\starttext
\ctxlua{print(string.format("%g",Binomial(100,60,0.25)))}
\stoptext

Re: [NTG-context] Command line tool for macro definitions

2018-01-14 Thread Hans Hagen

Dear list,

For TeX/LaTeX users there is the neat command line tool `texdef` with
which you can show the definition of a macro.  Here an example:

$ texdef -t latex section

\section:
\long macro:->\@startsection {section}{1}{\z@ }{-3.5ex \@plus -1ex
\@minus -.2ex}{2.3ex \@plus .2ex}{\normalfont \Large \bfseries }

Is there something similar for ConTeXt?  It is quite tedious to either
grep the full source or setup an extra dummy document to use \show or
\meaning.

i must admit that i never use \show for that ... anyhow, i'll provide

context --extra=meaning --once --pattern=*paper*
context --extra=meaning --once setuplayout
context --extra=meaning --once setup_layout

in the next beta

Hans
