Basic question

I have a bunch of old files that were probably created for Mark II. What is the current command for running Mark II instead of Mark IV? -- John Culleton Wexfordpress Book design and indexing.

font descriptions no longer work
by John Culleton 29 Jan '17

29 Jan '17

In all my recent books I have this subfile called fonts.tex. ----------------------------------------------------- \def\Fontsize{11} \font \rm = "file:MinionPro-Regular.otf:+liga;expansion=default;protrusion=quality" at \Fontsize bp \font \it = "file:MinionPro-It.otf" at \Fontsize bp \font \bf = "file:MinionPro-Bold.otf" at \Fontsize bp \font \firstlet = "file:MinionPro-Regular.otf" at 3\Fontsize bp \font \sc = "file:MinionPro-Regular.otf:+smcp" at 1.5\Fontsize bp \font \titlesans = "file:MyriadPro-BlackCond.otf" at 30bp \font \smalltitle = "file:MyriadPro-Regular.otf" at 20bp %\font \chapfont = "file:Raleway-ExtraLight.otf" at 80bp --------------------------------------------------------- When I use the \titlesans call in a document it errs off with this message > tex error on line 2 in file half.tex: ! Undefined control sequence It can be made to finish the run but the text on page half.tex is the ordinary body font. The fonts in question are in the directory where I am running context on a document in every case. I just installed the latest context in my home directory. I also have texlive installed. I copied the fonts to /usr/share/OTF, ran ft-cache as root. ran context as root. Nothing helped. Slackware 14.2 I have two book projects stalled. -- John Culleton Wexfordpress Book design and indexing.

Scripting with TeXLua
by Henning Hraban Ramm 27 Jan '17

27 Jan '17

Ahoi, Moonshiners! I rebuilt my invoice-writing setup and moved most of the logic from a python script to Lua within ConTeXt. Now I would like to replace the Python script completely. Can you suggest libraries that work well with texlua (or are even built-in), WRT - OO classes (ATM I’m using "classy" from https://github.com/siffiejoe/lua-classy) - UI (curses would be enough, maybe Qt, rather not wx. I found tekUI, but it won’t compile on OSX) - JSON (ATM I’ve my customers database in a JSON file, but I should probably move that to a Lua table anyway.) Regarding UI, maybe I could use some web forms and the infamous ConTeXt webserver. Experiences anyone? Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net GPG Key ID 1C9B22FD

Additional documentation/
by John Culleton 26 Jan '17

26 Jan '17

I have been away from context for a few years and my memory is fading in any case. I do remember a short tutorial that described how one could insert a text block in between two text columns or at the side of a column etc. I have downloaded the big manual today but that little tutorial would help. My questions: 1.Do you recall what I am referring to? 2. If so, what is its name? 3. Is it current enough to be useful today? Blessings on all who respond. -- John Culleton Wexfordpress Book design and indexing.

Bug in \startdocument
by Henri Menke 25 Jan '17

25 Jan '17

Dear devs, It is really convenient to set PDF metadata in \startdocument, however I noticed that there is a bug. The PDF subject is not set using metadata:subject but with metadata:subtitle. This is not a big issue by itself but merely a little confusing. What’s worse is that using metadata:subject throws an error which is completely unexpected at this point. Below you find the error message and a MWE to reproduce. --- ! Undefined control sequence <argument> \c!subject =\documentvariable {metadata:subject} --- \setupinteraction[state=start] \startdocument [ metadata:subject={Subject}, ] Hello World! \stopdocument

A better \definesymbol sought
by Rik Kabel 25 Jan '17

25 Jan '17

ConTeXters, I have been using \definesymbol for a while, and for most purposes it suffices. However, there is one thing that it does not do that perhaps it should. What it does not do is offer the option to center one glyph over another (horizontally and/or vertically) when it should be centered. Rather, it leaves the work to a process of tuning the horizontal and vertical levers (kern and raise here) to get something that is close, but rarely perfect. I also see some problems with the horizontal spacing around the new symbol, but that may be a function of the underlying glyphs here. The following example shows what I mean \definefont [Inits] [dejavusans] \usesymbols[mvs] \define\SqSteel{% \tfc \symbol[martinvogel 2][SquareSteel] } \define\RedSansA{% \tfx \Inits{\red A} } \definesymbol [MyMark] [\SqSteel\kern-.87em{\raise.38ex\hbox{\RedSansA}}] \define\Test{Some text \symbol[MyMark] some more text.\par} \starttext \Test \setupbodyfont[8pt] \Test \setupbodyfont[18pt] \Test \scale[factor=40]{\Test} \stoptext Can anyone suggest a better way to compose such symbols than using the raw TeX commands used here? Is there a more ConTeXt-ish way to do this? Is it possible to get options to center the glyphs from which the symbol is assembled (separate horizontal and vertical, with the ability to offset them)? Is there a ConTeXt way other than \definesymbol to create such combined symbols? -- Rik

Chapter-head: number, title and subtitle
by Robert Blackstone 25 Jan '17

25 Jan '17

Dear all, This is the upper half of a post I submitted on jan 7 with two questions (which was rather foolish of me), of which the second has already been answered by Aditya Mahajan. The first, still open, question was: Presently I’m restyling a PhD-dissertation to make it conform to the requirements of an external publisher. One of the items is the content and layout of the chapter-heads. What would be needed as a chapter-head, of Chapter 1 for instance, is, on two or, occasionally three, lines: - Chapter 1 (midaligned, boldface, smallish size (\tfa)) - some vertical space - Chapter title (midaligned, SmallCaps, slanted, \tfc) - some vertical space - (for some chapters) Chapter subtitle, (midaligned, SmallCaps, slanted, \tfb or smaller) Can ConTeXt be tweaked to yield such a chapter-head? Thanks in advance for any advice. Best regards, Robert Blackstone

problem with math: "\left" leads to "udefined symbol"
by j. van den hoff 24 Jan '17

24 Jan '17

hi everybody, after a 2 year hiatus I'm just giving `context' a second try (so, really not much experience so far). I updated to the latest version (0.63) before proceeding. two observations: 1. in a new document including assorted equations everything went fine until I tried something like \startformula x = \left 1 + 2 \right \stopformula which caused an error: 8<------------------------------------------------------------------ ! Undefined control sequence \strc_synonyms_insert_meaning ...urrentsynonymtag {#2}\fastsetup {\??simplel... \math_left ...ame \??mathleft \meaning \nexttoken \endcsname \expandafter \l... l.472 x = \left ( 1 + 2 \right ) 8<------------------------------------------------------------------ 2. an old document (not modified these 2 years) does no longer compile due to apparently the same problem (not understanding `\left', `\right'. question: my understanding is, that `context' supports "everything" out of the box (notably equations) and there is no need for explicit loading of additional packages? so `\left' etc. _should be defined (and it _used_ to work 2 years ago)? what am I missing? thx, joerg -- Using Opera's revolutionary email client: http://www.opera.com/mail/
