How to export to PDF-A?
by Matija Šuklje 17 May '16

17 May '16

Dear ConTeXt community, There is a document I wrote in ConTeXt that I’m required to submit in PDF-A. I’ve already done my RTFM homework: http://wiki.contextgarden.net/PDF/A including links in it, but can’t figure out how to apply it in practice. So far I’ve identified two possible issues: • I haven’t set it right in the source https://gitlab.com/fla-llm-thesis/fla-llm-thesis/ https://gitlab.com/context-modules/pful • The ICC profiles aren’t in the right place – I can’t figure out where they should be on a Linux system. Help much appreciated! cheers, Matija -- gsm: tel:+386.41.849.552 www: http://matija.suklje.name xmpp: matija.suklje(a)gabbler.org sip: matija_suklje(a)ippi.fr

definebodyfontenvironment
by Meer, Hans van der 16 May '16

16 May '16

I like to execute this statement \definebodyfontenvironment[somevalue] in order to avoid lots of error messages as such: fonts > bodyfont '8.0pt' is defined (can better be done global Is this definebodyfontenvironment macro fully executed each time it is called or does ConTeXt remember and execute it once only?

problem with \setupdelimitedtext
by Alan Bowen 16 May '16

16 May '16

In the following, the indentation using \startblockquote is twice what it should be: \setupdelimitedtext [blockquote] [before={\blank[small,fixed] \setupnarrower[left=1.5pc,right=0pc] \startnarrower[left,right] \noindentation}, after={\par\stopnarrower \blank[small,fixed] \noindentation}] \starttext \input ward \setupnarrower[left=1.5pc,right=0pc] \startnarrower[left,right] \input ward \stopnarrower \startblockquote \input ward \stopblockquote \stoptext What have I missed?

halign broken
by Meer, H. van der 16 May '16

16 May '16

There seems something very much amiss with \halign in later ConTeXt versions. This typesets fine in PlainTeX and is an example taken from a textbook. \tabskip=1em\halign{% \hfil\it#\hfil&\hfil#\hfil&#&\hfil#\crA&B&C&D\cr} Also in contextversion 2012.05.30 (from a TeXlive distribution). But it fails at least in ConTeXt ver: 2013.03.20 10:34 MKIV and in ConTeXt ver: 2013.04.16 12:08 MKIV beta with the following error ! Only one # is allowed per tab. system > tex > error on line 5 in file fixedwidth.tex: Only one # is allowed per tab ... 1 \starttext 2 contextversion=\contextversion\par 3 \tabskip=1em 4 \halign{% 5 >> \hfil\it#\hfil&\hfil#\hfil&#&\hfil#\cr 6 A&B&C&D\cr} 7 \stoptext l.5 \hfil\it#\hfil&\hfil# \hfil&#&\hfil#\cr Why? How primitive it may be, I would like to use \halign now and then. Hans van der Meer

With TeX, change may start as with Lua, only some better syntax for text input. I experimented a bit with giving Guile a C++ API, and then then there is a problem with that that C++ is statically typed whereas Guile is dynamic. For example, Guile does not distinguish statically between different types of numbers: integers, rationals, etc, so the proper way from the point of C++ is to only have open number type. But static typing is important in optimization. And giving implement traditional function syntax on top of Guile does not work well, because (f, x_1, …, x_k) does not correspond semantically exactly to f(x_1, …, x_n). And there is a problem with the Scheme strict evaluation. So such issues lead towards to the design of a new language, rather than relying on an already existing.

balancing columns

Hi Hans, I have the following sample: \mainlanguage[la] \definefontfamily [mainface] [serif] [TeX Gyre Pagella] \setupbodyfont[mainface, 7.8pt] \setupnotes[compress=yes] \setupnotations[alternative=serried] \definelinenote[aNote] \definelinenote[bNote][n=2] \definelinenote[cNote][n=3] \definelinenote[dNote][paragraph=yes] \def\ANote#1#2{#1\aNote{#1] #2}} \def\BNote#1#2{#1\bNote{#1] #2}} \def\CNote#1#2{#1\cNote{#1] #2}} \def\DNote#1#2{#1\dNote{#1] #2}} \starttext \dorecurse{50}{\startcolumns[n=2, balance=yes] \color[red]{% Aequivoca dicuntur quorum nomen solum commune est, secundum nomen vero substantiae ratio diversa, ut animal homo et quod pingitur.

The text for both columns is the same paragraph. Isn’t it a bug? BTW, is there any way to force that the text before or after a \column command remains always on the same column?

Problem with urls
by Robert Blackstone 15 May '16

15 May '16

Dear all, Can any of you explain, or, better, suggest a remedy for, the following problem: I want active urls in footnotes. With the same setups and correct urls, some of them become active and some others not. See the following ME: +++++++++++++++++ \setupinteraction[state=start,focus=standard,style=,color=blue,contrastcolor=] \starttext AA \footnote{\goto{http://gallica.bnf.fr/ark:/12148/btv1b90634431.r=Francois+Couperin.langEN}[url(http://gallica.bnf.fr/ark:/12148/btv1b90634431.r=Francois+Couperin.langEN)]} BB\footnote{\goto{http://imslp.org/wiki/Tuoni_ecclesiastici_con_li_loro_ver… CC \footnote{\goto{http://www.saraband.com.au/figured_bass.htm}[url(http://www.saraband.com.au/figured_bass.htm)]} \stoptext ++++++++++++++++++ When I process this with mkiv, the urls in AA and CC are active, while in BB it is not. Why? Thanks in advance for any help. Best regards, Robert Blackstone

what does rscale=auto achieve?
by Pablo Rodriguez 15 May '16

15 May '16

Dear list, I have the following sample: \definefallbackfamily [mainface] [rm] [DejaVu Serif] [preset=range:cyrillic, rscale=auto] \definefallbackfamily [mainface] [rm] [GFS Didot] [preset=range:greek, rscale=auto] \definefontfamily [mainface] [rm] [TeX Gyre Termes] \setupbodyfont[mainface] \starttext \startTEXpage[offset=1em] аaα \stopTEXpage \stoptext I thought that "rscale=auto" would scale the typeface so that its x-height would match the x-height from the main typeface. Since I don’t see any scaling, could anyone explain me what I’m missing? Many thanks for your help, Pablo -- http://www.ousia.tk

I had not noticed the comma and, yes, you are right, when I remove the comma I get an active url which opens a page on the desired site but without contents. When I add the comma in the address I get the desired page. I could add this instruction to the footnote but that seems to me to be a bit odd.

Thank you both, Best regards, Robert
