Expansion in bookmarks
by Christoph Reller 08 Jul '15

08 Jul '15

Dear all! I want to define a command that is to be used in a section title. Also I want to use \autoinsertnextspace with this command. In the following MWE, why do \This and \AName not work, while \TEX does work? I appreciate any feedback, Christoph MWE: \setupinteraction[state=start] \setupinteractionscreen[option=bookmark] \placebookmarks[section][section] \def\What{This\autoinsertnextspace} \definesorting[Name] \setupsorting[Name][next=\autoinsertnextspace] \Name[AName]{Knuth} \usemodule[abr-01] \setupsorting[logo][next=\autoinsertnextspace] \starttext \startsection[title={\What is puzzling}]\stopsection \startsection[title={\AName is puzzling}]\stopsection \startsection[title={\TEX is puzzling}]\stopsection \stoptext

Math alignment
by Hans Aberg 07 Jul '15

07 Jul '15

The example below shows the intended output when using original TeX code (compiled with ‘context' of TeX Live 2015): a pair of left braced formulas. The first comment shows what works in AMS-LaTeX. However, when trying similar ConTeXt commands, I get the error shown in the comment below. What ConTeXt command might use here? --- \setupformulas[location=left] \starttext \def\equlb#1{\left\{\eqalign{#1}\right.} %equation left braced % AMS-LaTeX %\def\equlb#1{\left\{ \begin{aligned} #1 \end{aligned}\right.} % equation left braced % ConTeXt error: You can't use `\halign' in math mode. %\def\equlb#1{\left\{ \startalign #1 \stopalign\right.} %\def\equlb#1{\left\{ \startmathalignment #1 \stopmathalignment\right.} \startformula \placeformula[JcoordDef] J^j:\equlb{ω^0 &→ 0 \cr ω^j &→ 0} \quad \equlb{ω^k &→ ω^l \cr ω^l &→ -ω^k} \stopformula \stoptext ---

hyphenation exceptions?
by dr. Hans van der Meer 07 Jul '15

07 Jul '15

Has something happened to hyphenation? The following does not work \language[nl] \startexceptions[nl] Am-ster-dam \stopexceptions Neither does \hyphenation{Am-ster-dam} Only in the context-source Am\-ster\-dam is working. How to load a series of hyphenation exceptions instead of explicitely spelling out the breakpoints in the source? Hans van der Meer

Environments
by Hans Aberg 07 Jul '15

07 Jul '15

ConTeXt does not seem to have LaTeX style environments. FYI, for the latter, I developed [1] a long time ago more advanced ones: The environments admit hooks, i.e., code executed before and after the local group. The name can be omitted in the closing, which works also when using one environment to define a new. And a more compact syntax. 1. https://secure2.storegate.com/Shares/Home.aspx?ShareID=db8465b3-112f-4194-8… Compile 'lualatex test0.tex’.

Smallmatrix not implemented
by Hans Aberg 06 Jul '15

06 Jul '15

Smallmatrix from AMS-TeX is not implemented in ConTeXt (Tex Live 2015), though crossed out in m-newmat.tex. I found this old post: http://www.ntg.nl/pipermail/ntg-context/2005/013146.html

\appendtoks for options
by Pablo Rodriguez 06 Jul '15

06 Jul '15

Dear list, I have the following sample: \appendtoks \let\sethyphenationfeatures[underscore]\space \to \simplifiedcommands \setupinteraction[state=start] \placebookmarks[chapter] \starttext \chapter{\sethyphenationfeatures[underscore] code} \stoptext Is there a way that I can add the whole "\sethyphenationfeatures[underscore]" to \simplifiedcommands? All I want is to have the whole command removed from the PDF bookmarks. Many thanks for your help, Pablo -- http://www.ousia.tk

font features in XeTeX
by Robert Zydenbos 06 Jul '15

06 Jul '15

Dear ConTeXt folk, Is there any simple way to pass font features as a parameter to XeConTeXt? i am thinking of things like what in LaTeX would be (between square brackets) "\setromanfont [AutoFakeSlant=0.5, AutoFakeBold=0.5] {Doulos SIL Phon}". There has to be some way to do this, but I seem unable to find it in the documentatioin I have. RZ

Integral spacing
by Hans Aberg 06 Jul '15

06 Jul '15

I get too much spacing after the integrals when using ‘context’ (TeX Live 2015) - see first example below. Cf. the second example below, compiled with luatex. In ConTeXt, the result is the same regardless of body font, and also if using original TeX \int. --- context --- \setupbodyfont[xits,10pt] %\setupbodyfont[stix,10pt] \starttext \startformula ⟨φ|ψ⟩ ≔ ∫… ∫ dx_1 … dx_n\, φ(x_1, …, x_n)^* ψ(x_1, …, x_n) \stopformula \startformula ⟨φ|ψ⟩ ≔ \int … \int dx_1 … dx_n\, φ(x_1, …, x_n)^* ψ(x_1, …, x_n) \stopformula \stoptext --- --- luatex --- $$ \left<\phi|\psi\right> = \int \ldots \int dx_1 \ldots dx_n\, \phi(x_1, \ldots, x_n)^* \psi(x_1, \ldots, x_n) $$ \end ---

Unfortunately, as far as I know, some screen readers (for the visually impaired) use these as navigation aids, i.e. press button "jump to next section", and the reader will look for the next section marked as <Sect> or something. Is it difficult to make the mapping user-defineable in the source tex-file? Say, like such a command: \definemapping[ section=Sect, sectiontitle=H sectionnumber=H, ... tablerow=TR ... ] It would then give users the control on what to map onto what, depending on what kind of documents they create. >> All in all, these seem to be the only issues that prevent accessible PDF >> documents with context.

I can fully understand that such things are not of the highest priority. Nevertheless accessibility plays more and more a role, e.g. lately, even conferences like http://chi2015.acm.org/authors/guide-to-an-accessible-submission/ require accessible pdfs (the workflow they suggest, i.e. tagging a pdf by acrobat pro after compiling of course doesn't work at all - the generated structure is useless). Hence, for some users, it makes all the difference. For example for me and some other friends, it would allow to change from using Microsoft Word to a ConTeXt based workflow. cheers - Dominik

New btx code problem with quote protrusion
by Rik Kabel 05 Jul '15

05 Jul '15

List folk: In the MWE below, everything builds cleanly if the \setupdelimitedtext line is removed. With it removed, however, quote marks protrusion looks poor when nearby quote marks in non-quotation text is allowed to protrude. The happens when there is a citation in a footnote in the quoted text. Is this a bug, or simply something not yet ready with the new regime, or am I doing something wrong? % The next line should allow \startquotation to protrude quotes \setupdelimitedtext[quotation][method=font] % However, it causes the new bib code to fail when there is a % footnote containing a citation in the quote. See % http://www.mail-archive.com/ntg-context@ntg.nl/msg35580.html \definefontfeature [default][protrusion=quality] \setupalign [hz,hanging] \usebtxdataset [xx.bib] \starttext \startparagraph\noindent There is a citation in the footnote to this standard paragraph\footnote{This footnote has a citation \cite[One].} \stopparagraph \startquotation[right] There is a citation in the footnote to this block quotation\footnote{This footnote has a citation \cite[Two].} \stopquotation \startparagraph\noindent “There is a citation in the footnote to this standard paragraph\footnote{This footnote has a citation \cite[One].}” \stopparagraph \placelistofpublications \stoptext And the corresponding xx.bib file: @BOOK{One, author = {A.

Author}, title = {A Pipe}, journal = {The Journal}, year = {2018}, volume = {32}, number = {3}, pages = {42--69}, } -- Rik Kabel
