State of documentation of ConTeXt?
by Gerben Wierda 23 Jul '14

23 Jul '14

Hello guys, I am restarting a book project I started a several years back. At that time I set up a copy of another project I am working on in ConTeXt, so with the products/environment/chapters structure, added Mac fonts to my setup, using texexec for compilation. Now that I am restarting, I am returning to ConTeXt. The first thing I did was go to contextgarden and look for updated documentation. What I found was the over 10-year old documentation (contextref.pdf) with green boxes stating things like “TODO: Add some text about recent developments, especially the split between mkii and mkiv”. Is there up-to-date and reasonably complete ConTeXt documentation these days? G

Why is my output body text in 15pt?
by Gerben Wierda 23 Jul '14

23 Jul '14

I am typesetting a small pocketbook. I’m using mkii and the standard products/environment/chapters structure. I am trying to create a small paperbook size book with 11pt Optima font (using the converted font on my Mac). Everything works, except the body text is in 15pt in the PDF. Now, I did all this font setup stuff years and years ago (I think the whole GTAMacFonts doesn’t work/exist anymore, I just keep it running on my system) and of course I suspect something not quite right in that part, but when I completely leave out the Optima stuff, I get CMR in 15pt, so that is probably not it. When in CRM, I see log entries like [7.5] Overfull \hbox (4.50882pt too wide) in paragraph at lines 36--46 \*12ptrmtfrm*: rat-ings in-sti-tute are ca-pa-ble of han-dling this amount \hbox(8.26648+2.33331)x258.10477, glue set - 1.0 .\*12ptrmtfrm*: r .\*12ptrmtfrm*: a .\*12ptrmtfrm*: t .\discretionary ..\*12ptrmtfrm*: - .\*12ptrmtfrm*: i .etc. Which seems to indicate that the font is 12pt. But why is the document in 15pt text? My environment contains (amongst other things): \definepapersize[smallpaperback][width=5in,height=8in] \setuppapersize[smallpaperback][smallpaperback] \setuplayout[location=doublesided] \setuppagenumbering[alternative=doublesided] \setupsectionblock[frontpart][page=no] \setupsectionblock[bodypart][page=no] \setupsectionblock[appendix][page=no] \setupsectionblock[backpart][page=no] % Every chapter body text starts with lettrine: \usemodule[lettrine] \setuplettrine[Lines=3, Hang=.5, Oversize=0, Raise=0, Findent=0pt, Nindent=0em, Slope=0em, Ante=, FontHook=, TextFont=\sc, Image=no] % Every chapter starts with a quote on the LHS page: \setuphead [chapter] [page=, before={\setups[chapter:before]}, after={\setups[chapter:after]}] \startsetups chapter:before \page[left] \noheaderandfooterlines \startalignment[left,nothyphenated] \startnarrower[4*left] \em \getbuffer[chapter:quote] \stopnarrower \stopalignment \resetsetups[quote:text] \page[right] \noheaderandfooterlines \blank[force,2*big] \stopsetups \startsetups chapter:after \blank[3*big] \stopsetups \setuptolerance[horizontal=strict] \setupcolors[state=start] \setupcolor[rgb] % \setupquote[style=small] \setupnarrower[left=1cm,right=0.5cm] % \usetypescript[serif,sans,mono] [hanging] [normal] % Bypassing type-gtamacfonts.tex \starttypescript [sans,serif] [optima] [texnansi,ec] \definefontsynonym [Optima-Regular] [\typescriptthree-OptimaRegular] [encoding=\typescriptthree] \definefontsynonym [Optima-Italic] [\typescriptthree-OptimaItalic] [encoding=\typescriptthree] \definefontsynonym [Optima-Bold] [\typescriptthree-OptimaBold] [encoding=\typescriptthree] \definefontsynonym [Optima-BoldItalic] [\typescriptthree-OptimaBoldItalic] [encoding=\typescriptthree] \definefontsynonym [Optima-ExtraBlack] [\typescriptthree-OptimaExtraBlack] [encoding=\typescriptthree] \stoptypescript \starttypescript [sans,serif] [optima] [name] \setups [font:fallback:\typescriptone] \definefontsynonym [\typescriptprefix\typescriptone] [Optima-Regular] \definefontsynonym [\typescriptprefix\typescriptone Italic] [Optima-Italic] \definefontsynonym [\typescriptprefix\typescriptone Bold] [Optima-Bold] \definefontsynonym [\typescriptprefix\typescriptone BoldItalic] [Optima-BoldItalic] \definefontsynonym [\typescriptprefix\typescriptone Black] [Optima-ExtraBlack] \stoptypescript \definetypeface[allsans][rm][serif][optima][default][encoding=texnansi] \definetypeface[allsans][ss][sans][optima][default][encoding=texnansi] \loadmapfile [gtamacfonts.map] \setupbodyfont[allsans,11pt]

framedtext and itemize
by Meer, H. van der 22 Jul '14

22 Jul '14

I have a question regarding the interplay between framedtext and itemize. Example \startitemize[n]\startitem \startframedtext[left][width=0.5\textwidth]\leavevmode some text \stopframedtext \stopitem\stopitemize The framedtext is put on the next line instead of on the first of the item. [cid:3B8394EB-ADB8-4DA9-9E09-6ACFB9389BB4] How do I get here the top frameline of the framedtext aligned with the 1. of the itemnumber? Playing with the location-parameter on the \startframedtext doesn't seem to make any difference. Especially I would like the baseline of the first line inside the framed text to be at the same level as the itemlabel. Hans van der Meer

\framed versus \inframed
by Herbert Voss 22 Jul '14

22 Jul '14

I'd expect a double frame for a nested \inframed, too. And also fog in the last row always on the baseline fort \inframed. \starttext foo\framed{\framed{foo}} \inframed{\inframed{foo}} foo fog\framed{\framed{fog}} \inframed{\inframed{fog}} fog \setupframed[strut=no] fog\framed{\framed{fog}} \inframed{\inframed{fog}} fog \stoptext running current minimal Herbert

aligning framedtexts inside framed
by Meer, H. van der 22 Jul '14

22 Jul '14

In search of a nice presentation of two passages of text I am trying to put two \framedtext's inside a \framed with their top at the same level. However, I have not been able to accomplish this. Instead they align their bottom. Example with its result: \framed[location=top]\bgroup \hsize=0.5\textwidth \startframedtext[left][width=0.5\textwidth,location=top]\leavevmode some text \stopframedtext \startframedtext[left][width=0.5\textwidth,location=top]\leavevmode some other text\crlf of more lines \stopframedtext \egroup [cid:B80CDDB1-1D08-4FEE-8B80-B1C0C11AC256] Changing the location parameter made no difference, introducing an align ruined the placement on the same line. How do I get the toplines of the inner frames at the same height? Hans van der Meer

\underbar
by Herbert Voss 21 Jul '14

21 Jul '14

>From the contextref.pdf, p 262 \underbar A disadvantage of this command is that words can no longer be hyphenated. This is a nasty side--effect. But we do support nested underlining. This commant is wrong, right? Hyphenation is supported. Herbert

Caption whitespace overflows page
by Rik Kabel 20 Jul '14

20 Jul '14

How can I get rid of the space at the top of the first line of text on page three in the following MWE. The \setupfloats[spaceafter=none] masks the problem rather than addresses the problem directly. Playing with the size of the figures (changing them to 3cm) shows that the caption text is not pushed to the second page, just some whitespace imputed to them. This happens with TL2013 and with the latest (20140325) standalone beta. I may be able to get away with the figure overflowing into the footnote space by avoiding footnotes, but the space on the next page is just ugly. \setuppapersize[A6] \setupexternalfigures[location={local,default}] \setupfloats[spaceafter=none] \starttext \input{knuth} \placefigure[left]{Caption} {\startcombination[1*3] {\externalfigure[cow.pdf][height=2cm]}{cow} {\externalfigure[cow.pdf][height=2cm]}{cow} {\externalfigure[cow.pdf][height=2cm]}{cow} \stopcombination} \input{knuth} \input{knuth} \stoptext -- Rik Kabel

Fonthandling/protrusion question: handling of left margin
by Rob Heusdens 18 Jul '14

18 Jul '14

Short question about the font feature protrusion. This handles certain characters that get shifted into the right margin to make a more visable straight right margin. But can this font feature also handle left margin? For example, sentences that start in the left margin and begin with a quotation, there you would want the same effect also in the left margin. I currently use \kern-1ex to achieve the same effect for a sentence that commences on the left margin and starts with a quotation. Greetings, Rob

question about unwanted locations of pagebreaks
by Rob Heusdens 18 Jul '14

18 Jul '14

The very last thing to do when finalizing a multi-page document is checking where the page breaks occur, and make corrections accordingly, if the pagebreak occurs at a location you do not want. Of course, you can take all kind of measures on before hand to avoid 'bad' places, like avoiding pagebreaks directly after a new section and before any of the body text, etc. But the degrees of freedom for context to handle this and to avoid (typographically) 'bad' pagebreak locations are I suppose limited. Is there a way (already implemented) in Context in which one can add some degrees of freedom to avoid bad pagebreak locations. For instance with elements that can vertically stretch (between some minimum and maximum value) and can be placed optionally (and which could for instance include a fancy decoration, like fancybreak module provides)? (I guess this is also the way in which typesetters in the past dealt with this problem). Greetings, Rob

Bug with complex contextual opentype feature
by Georg Duffner 18 Jul '14

18 Jul '14

Hello All, I’ve recently been experimenting with contextual features in EB Garamond and LuaTeX’s output is puzzling. As a showcase, I tried to implement the famous TeX logos with opentype. This is realized in a feature "xtex" with GSUB and GPOS lookup tables for substituting some glyphs and for positioning them horizontally and vertically: ##### OT feature code for TeX logos lookup xtex_sub1 { sub X e' T e X by e.xtex2; # e.xtex2 is a reversed copy of E sub X e' L a T e X by e.xtex2; sub L a' T e X by a.sc; sub T e' X by e.xtex1; # e.xtex1 is a copy of E sub L a.sc T e.xtex1 X [two two.lnum two.taboldstyle two.tablining] e' by e.xtex3; # e.xtex3 is a copy of epsilon } xtex_sub1; lookup xtex_pos1 { pos X e.xtex2' <-130 -180 -320 0> T; pos X e.xtex2' <-130 -180 -200 0> L; pos X [two two.lnum two.taboldstyle two.tablining] e.xtex3' <0 -180 0 0>; pos L a.sc' <-330 210 -490 0> T e.xtex1 X; pos T e.xtex1' <-180 -180 -280 0> X; }xtex_pos1; feature xtex { lookup xtex_sub1; lookup xtex_pos1; } xtex; ##### LuaTeX only processes the sequence "XeTeX" where it substitutes the first "e" by e.xtex1 instead of e.xtex2. Then it positions it with respect to "X" but not to "T". All the other parts of the lookups are ignored as well. The font file can be downloaded from http://www.georgduffner.at/ebgaramond/fonts/EBGaramond12-Regular.otf. The expected output can be seen at the bottom of this page: http://www.georgduffner.at/ebgaramond/design.html with Firefox and Chrome/Chromium and in the attached screenshot (from SortsmillEditor). Like the browsers, XeLaTeX’s output is correct.
