Multi-letter words/identifiers in math
by Shuxian Wang 30 Sep '19

30 Sep '19

Dear list, I am trying to typeset some multi-letter words/identifiers in mathematical formulas. Currently, doing things like `{\it variable}` or `{\mathit variable}` under math mode will cause the engine to shift all characters into the corresponding unicode mathematical alphanumeric block position. However, most OpenType fonts that have good support for unicode math are optimized for single-character usage. Therefore, the outcome of such method is non-ideal, as no kerning or ligatures will be enabled. Especially, this gives bad output when typesetting variable names with combinations like “ffi”. Looking through some past discussions on the list, I am aware of the usage of `\mathword` and `\mathtext`. Using those command will keep all the characters “as is” and typeset them under text mode (as far as I can tell). But those commands switch to the main body fonts temporarily to accomplish this. Sometime when using a different math font than the main font (like Palatino with Latin Modern Math), I wish my variable names can also be in the math font (or at least very similar, such as Latin Modern vs. Latin Modern Math) to better merge with the formula. The way I am currently doing is to introduce some “math text fonts” that is different from the main text font but close to the math font. And with custom font switchers like `\mwrm` and `\mwit` to help me define things like ``` \def\wordrm#1{\mbox{\mwrm #1}} \def\wordit#1{\mbox{\mwit #1}} ``` Am I missing some builtin functionalities or easier ways to do this? If not, would it be a good idea to extend the functionality of `\mathword` so it lifts out the restriction of only using the main text font? Thanks! Shuxian Wang

placefigure right or left error in ver: 2018.04.04 00:51 MKIV

Hello there, I recently upgraded to ConTeXt ver: 2018.04.04 00:51 MKIV and found that the following simple code gives an error, where as it compiled without complaining in ver: 2017.05.15 21:48. \setupexternalfigures[location={local,default}] \starttext \input ward \placefigure[left,none]{}{\externalfigure[cow][width=3cm]} \input ward \stoptext The error happens when the location of placefigure is left or right, but not with center.

Columns with non-equal width; nested columns

25 Sep '19

Hello, I need to get columns like this: | | 1b | | 1a | | +-------------+ | | 2a | 2b | | | | | | I tried the following: ---- \starttext \startcolumns[n=2] % How to tell that ratio between columns should be 2:1? \input knuth % Be 1a \startcolumns[n=2] \input ward % Be 2a \column \input ward % Be 2b \stopcolumns \column \input knuth % Be 1b \stopcolumns \stoptext ---- - Is it possible to nest columns? - If not, is there another solution? - How to specify ratio of widths of columns?

poem as a sidefloat
by Henning Hraban Ramm 25 Sep '19

25 Sep '19

Hi, I’d like to have a small poem beside my text. My approach doesn’t work, with or without \framed: Since I need this only once, I thought I don’t need to define or setup my own float. \setupfloat inherits from \setupframed, but the parameters width, style and background(color) don’t work. Aren’t they supposed to work in \startplacefloat? How can I suppress the caption? ("none" is supposed to work with \placefloat, but at least doesn’t in \startplacefloat) With or without framed, vbox and lines didn’t change much. (Of course \framed adds a frame, but the text isn’t within). \starttext \dorecurse{2}{\input knuth} \startplacefloat[ title=none, % doesn’t work numbering=no, % wrong location=left, width=.33\textwidth, % doesn’t work style=\tt, % doesn’t work background=color,backgroundcolor=cyan, % doesn’t work ]% %\framed[ % width=.33\textwidth, % style=\tt, % background=color,backgroundcolor=yellow, %]{\vbox{% \startlines lichtung manche meinen lechts und rinks kann man nicht velwechsern. werch ein illtum! \wordright{ernst jandl} \stoplines %}} \stopplacefloat \dorecurse{2}{\input knuth} \stoptext Greetlings, Hraban --- https://www.fiee.net http://wiki.contextgarden.net https://www.dreiviertelhaus.de GPG Key ID 1C9B22FD

This mailing list is not DKIM (DMARC) compatible
by Gerben Wierda 25 Sep '19

25 Sep '19

The footer that is added to each message in this list is not DKIM (and thus DMARC) compatible. DKIM requires the ability to create a signature on a set of headers and the body. By changing the body, the DKIM signature fails and the resulting messages sent by the mail list may in the future be blocked by more and more mail servers.

stacking of margin "footnotes"
by Henning Hraban Ramm 25 Sep '19

25 Sep '19

BTW yesterday I recognized that stacking of my margin notes now works without my manual shifting. That’s great, thank you! The attached example is probably not minimal, but just in case someone’s interested. Best, Hraban

Re: [NTG-context] OpenBSD install broken

Do you have any clue what could be done to make it work properly on OpenBSD? Mojca Shell scripting has always been a mystery to me. For what it is worth, however, here is what I was able to come up with: megaera$ cat test echo "$SHELL" echo "$KSH_VERSION" SCRIPTPATH="$_" OWNPATH=$(cd -P -- "$(dirname -- "$SCRIPTPATH")" && pwd -P) echo $OWNPATH megaera$ ./test /bin/ksh @(#)PD KSH v5.2.14 99/07/13.2 /home/<name>/Temp It seems that OpenBSD uses public domain ksh also known as ksh88, as opposed to the more common ksh93. I also found on the internet the following code snippet for testing ksh versions: case "$KSH_VERSION" in (*MIRBSD*|*PD*|*LEGACY*) printf '%s\n' "$KSH_VERSION" ;; (*) [ -z "$ERRNO" ] && printf '%s\n' "${.sh.version}" || echo ksh88/86 ;; esac All that said however, while it would be nice to have setuptex work on OpenBSD also, I think anyone using it can set their own paths if they have to.
