Font DejaVu with a font for Mathematics
by Fabrice Couvreur 06 Sep '17

06 Sep '17

Hello, I use for the documents of my students the font DejaVu because I find that it is very readable on paper. Unfortunately, this is not a font for writing Mathematics. I would like to use DejaVu font for text and a font to write mathematical formulas. What do you recommend ? Thank you. Fabrice

There seems to be, however, still a minor issue with a more complete MWE: \math{ \startmatrix \NC A \NC B \NR \NC C \NC D \NR \stopmatrix} The resulting structure tree is as follows: <document> '-<math> '-<mrow> '-<mtext> '-<mrow> |-<mrow> | '-<mtr> | |-<mtd> | | '-<math> | | '-<mrow> | | '-<mi> | | '-"A" | '-<mtd> | '-<math> | '-<mrow> | '-<mi> | '-"B" |-<mrow> (*) |-<mrow> | '-<mtr> | |-<mtd> | | '-<math> | | '-<mrow> | | '-<mi> | | '-"C" | '-<mtd> | '-<math> | '-<mrow> | '-<mi> | '-"D" '-<mrow> (*) The elements marked with (*) are IMHO unnecessary. Do you agree? Cheers Christoph

One can configure those things but the absense of rules and presence of fences matters too (all kind of inter-this-or-that and above-below-this-or-that playts a role).

MS Office Chinese fonts in ConTeXt
by Martin Bruchanov 05 Sep '17

05 Sep '17

Hi all, I was trying to create a Chinese document. However, it was quite difficult to find actual information and find fonts... Here is the result: https://github.com/BruXy/ConTeXt-Chinese There is still wrong numbering of Tables and I am not sure how to convert mschinese.ctex into module, but maybe somebody will help. Regards, BruXy PS: It you have some other working Chinese ConTeXt documents, I would be happy to get inspired.

How to "terminate" or break from a side float?
by Alan Braslau 04 Sep '17

04 Sep '17

Hi, Below is a MWE achieving the desired behavior, but is a messy solution. Given a side float, how can one "terminate" filling text or break to after the side float? There *must* be a very simple and proper command to do this, but I have not found it. Alan \starttext \startplacefigure [location={left,none}] \framed [width=.3\textwidth,height=.3\textwidth] {} \stopplacefigure \input ward \startplacefigure [location={force,none}] (this forces a break) \stopplacefigure \input knuth \stoptext

Empty page to suppress header (background) frame
by Procházka Lukáš Ing. 04 Sep '17

04 Sep '17

Hello, suppose the following code: ---- \setuplayout[header=5mm,headerdistance=5mm,] \setupbackgrounds[header][text][bottomframe=on] \setupheadertexts[left][right] \starttext Page 1 \page[empty,blank] Page 2 \stoptext ---- Page 2 in this sample is empty - no text and no header/footer - but it KEEPS FRAME around HEADER. How to: - define header to be framed normally and - to be "frame-free" when \page[empty] (and/or maybe \page[blank]) is called? Best regards, Lukas -- Ing.

The binomial coefficients do not look optimal
by Mikael P. Sundqvist 02 Sep '17

02 Sep '17

Hi, I stumbled upon this (see the attached file for the result): %%% Test file \setupbodyfont[10pt] \starttext \startTEXpage[offset=10pt] \type{\tbinom{n}{k}}: $\tbinom{n}{k}$, (does not look good, the vertical space between $n$ and $k$ is too big) \par \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 parenthesis, even for displayed formulas).\par \stopTEXpage \stoptext %%% End of test file 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). /Mikael PS The result looked better if I used the lucida fonts, if that helps.

Re: [NTG-context] about "unknown script 'context.lus' or 'max-context.lua'"
by Jeong Dal 02 Sep '17

02 Sep '17

Dear Hans van der Meer, According to your word, I added the PATH to texmf-dist(texlive 2017) to the ConTeXt(LuaTex).engine directly. And, in the terminal, run mtxrun —generate and run luatools —generate once more. Then ConTeXt(LuaTeX) is working fine. Now, I can compile ConTeXt files using either texlive-2017 or minimal-beta. Thank you again. Best regards, Dalyoung
