Dot fills shifted down
by Procházka Lukáš Ing. 31 Jan '17

31 Jan '17

Hello, the following code: ---- \definefiller [DotFill] [alternative=symbol, symbol=., width=.5em, style=\txx] Fill here: \filler[DotFill]{} ---- produces filler with dots on the baseline. Is there a way to shift the dots a bit lower, bellow the baseline, e.g. to 0.25em bellow? Best regards, Lukas -- Ing.

How to define a new font style using \definefontstyle?
by Antoine Cailliau 31 Jan '17

31 Jan '17

Hi, I'm trying to declare a new font style. I declare it with \definefontstyle [sx] [sx] but the compilation fails when I use \sx in my document. I found an older message from 2009 similar to my issue but with public solution. May be some private response from Hans Hagen is missing? ( https://mailman.ntg.nl/pipermail/ntg-context/2009/043067.html) Here is a minimal example: \definefontstyle [sx] [sx] \definetypeface [source] [sx] [semiextended] [myriadpro] [optical] \starttypescript [semiextended] [optical] [size] \definebodyfont [11pt] [sx] [tf=SansSemiExtended sa 1] \stoptypescript \starttypescript [semiextended] [myriadpro] \definefontsynonym [SansSemiExtended] [file:MyriadPro-SemiExt.otf] [features=default] \stoptypescript \starttext {\sx ABCDEFGHIJKLM\par NOPQRSTUVWXYZ\par abcdefghijklm\par nopqrstuvwxyz\par 1234567890} \stoptext Thanks for your help, Antoine C.

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
