Hi Lukáš,

could you add this info to the wiki?

Re: [NTG-context] The binomial coefficients do not look optimal

Hi,

I stumbled upon this (see the attached file for the result):

\type{\binom{n}{k}}: $\binom{n}{k}$ (looks fine to me)\par
\type{\dbinom{n}{k}}: $\dbinom{n}{k}$ (does not look good, too big

I think something should be changed to get the binomial coefficients to 
look better. In particular I am concerned about the rather big 
parenthesis in displaystyle (and not so much about the vertical space 
issue in \tbinom).

PS The result looked better if I used the lucida fonts, if that helps.
This is indeed font dependent. These binoms use a low level tex 
primitive that uses a threshold for steps and that one is part of the 
math parameters of a font and these are not that good for lm. As I'm 
looking into some other low level side effect I was in the mood for a 
configuration option for \setupmathfractions.


So, in the next beta you can get the effects iof the attached:

- relate the threshold to the bodyfont size
- use normal left/right fences instead

fwiw, cambria and pagella look better too. Upto you to wikify it.

[NTG-context] Letter module: Subject below opening

2017-09-01 Thread Parchd 
British letters typically have the subject below the opening.

A stackexchange user asked many moons ago how to accomplish this in
ConTeXt, and received a rather hackish response
(https://tex.stackexchange.com/questions/22438/how-to-place-the-subject-line-under-the-greeting-line-in-t-letter-module-in-cont).

ConTeXt and the letter module have changed a lot since then, if my
experience is correct. Is there a better solution than given there?

Best,

Parchd.

Re: [NTG-context] about "unknown script 'context.lus' or 'max-context.lua'"

2017-09-01 Thread Meer, Hans van der 
Allthough I am working with the ConTeXt beta version, I hope you will get 
things running in TeXShop by analogy as it does for me.

On OSX there are directories used by TeXShop one of which is  
~/Library/Engines. The text files there contain scripts that callup a tex run. 
In my case I have a text file called BetaCur.engine to be found in the run 
popup button of TeXShop. In it I have:
#!/bin/bash
source ~/.bashrc
mtxrun --script context "$1"

In the .bashrc file in my home directory the directory where the ConTeXt files 
reside is given amongst other defines:
CONTEXTROOT=$HOME/Applications/TeX-programs/directory-of-my-contextbeta-files/tex
export CONTEXTROOT
PATH=$PATH:$CONTEXTROOT/texmf-osx-64/bin

I hope this will help you to customize things to your setup.

Dear all,

1. Today, I installed TeXlive 2017 using MacTeX and do a simple test using 
TeXshop.

When I run a sample file using “ConTeXt(LuaTeX)”, then I got an error message:

mtxrun  | unknown script 'context.lua' or 'mtx-context.lua'

I also did “mtxrun —generate”in the terminal which runs well.  But “luatools 
—generate” also issue the similar error message:

mtxrun  | unknown script ‘base.lua’ or 'mtx-base.lua'

However, it runs well under Stand-alone ConTeXt.
What I have to do to make TeXlive work?

2. Recently, I also installed Textadept in OS X for test, and follow the steps 
explained in the wiki.

If I open textadept in the terminal(open -a textadept), ConTeXt, lua, Python 
worked OK.
But it  issued an error message as following  when I open it directly from the 
application folder.

> mtxrun --autogenerate --script context --autopdf --purge --synctex=-1 
> "Main.tex"
Failed to execute child process "mtxrun" (No such file or directory)
> exit status: 256

In the terminal, echo $PATH contains the folder “/Library/TeX/texbin” which 
contains all executables of TeXlive 2017.
Is there anything that I have to do more?

Thank you for reading.

Best regards,

Dalyoung

Re: [NTG-context] Empty page to suppress header (background) frame

2017-09-01 Thread Procházka Lukáš Ing . 

Hello Pablo,

you inspired me:


\setuplayout[header=5mm,headerdistance=5mm,]
\setupheader
  [text]
  [before={\startframed[frame=off,bottomframe=on,framecolor=blue,]},
   after={\stopframed},
  ]
\setupheadertexts[left][right]

\starttext
  Page 1
  \page[empty,blank]
  Page 2
\stoptext


Best regards,

Lukas

Hi Lukáš,

from your sample, I wonder whether you need a complete frame or only a
rule in the header.

If you only need a rule, this is the way to go:

\setuplayout[header=5mm,headerdistance=5mm,]
%~ \setupheader[text][after=\vskip 4pt\hrule]
\setupheader[text][after={\blackrule[
width=\textwidth,
height=1em]}]
\setupheadertexts[left][right]

\starttext
   Page 1
   \page[empty,blank]
   Page 2
\stoptext

I hope it helps,

Pablo
