math: formula alignment: confusion about `left` and `right` alignment
by Paul Menzel 24 Jul '11

24 Jul '11

Dear ConTeXt folks, looking at the Wiki page about changing the formula alignment [1] and testing the following minimal example, which is also attached, I would have thought that `align=right` would mean, that the formula is put to the right side. But is aligned to the left side instead. --- 8< --- minimal example --- >8 --- \starttext Right align. \setupformulas[align=right] \startformula ℕ ⊂ ℝ \stopformula Left align. \setupformulas[align=left] \startformula ℝ ⊂ ℂ \stopformula \stoptext --- 8< --- minimal example --- >8 --- What is wrong with the way I am looking at this? Searching for »latex align formula left right« I could not find an answer either. Thanks, Paul [1] http://wiki.contextgarden.net/Math/Display#Changing_Formula_alignment

\setupmathematics: autopunctuation only for certain symbols like . or ,
by Paul Menzel 24 Jul '11

24 Jul '11

Dear ConTeXt folks, if I am not mistaken `autopunctuation` [1] should prevent the space after the decimal mark [2] like in »1,23« or »1.23«. The following minimal example, which is also attached, indicates that the space is also not added for semicolon »;«. --- 8< --- minimal example --- >8 --- \starttext \setupformulas[align=right] \startformula ℕ ≔ \left\{ 0; 1; 2; 3; … \right\} \stopformula \setupmathematics[autopunctuation=no] \startformula ℕ ≔ \left\{ 0; 1; 2; 3; … \right\} \stopformula \stoptext --- 8< --- minimal example --- >8 --- I wonder if this is on purpose because the Wiki page [2] does not list the semicolon as a decimal mark. Would it be possible to take the semicolon out of the handling of `autopunctuation`? Thanks, Paul [1] http://wiki.contextgarden.net/Math_setups [2] https://secure.wikimedia.org/wikipedia/en/wiki/Decimal_mark

Citing online sources
by Christian 23 Jul '11

23 Jul '11

Good evening, what is the recommended approach to citing online sources? BibTeX does not understand the @ONLINE type, as opposed to BibLaTeX. Internet sources have other important information than book. For example here I want to show the URL in the bibliography, whereas for don't want it to be shown for books etc. Also the date of the last access is needed. This would be a nice format (first book, than online source): John, D. (2011). Johnny's big Adventure. 2nd ed. Made-Up-Publisher. Some Place else. Times Online (2011), Title of article. wwww.times-online.com/323/title- of-article.com (last access: 01.01.2011) Note also that the author field is not automatically abbreviated. Is there an approach to this or do I have to cheat in the bbl file in order to get the desired output? Regards, Christian

Hello everybody, I'm on Ubuntu 11.04 64bits, and try to generate a pdf without success. On ubuntu 10.10 64bit, it works perfectly, but after the upgrade, no ... So I ask you if you have any idea.

math: using bold charaters for number sets
by Paul Menzel 23 Jul '11

23 Jul '11

Dear ConTeXt folks, according to [1] the number sets were originally set using bold characters and only on the blackboard the double strokes were used. ConTeXt defines for example `\naturalnumbers` or `\reals` [2] which are set using double strokes. How can I redefine those to be just bold? Thanks, Paul PS: Does somebody actually use these commands (`\naturalnumbers`, …`) or do you define for example `\N`?

mkiv and non-universal sans-serif kerning
by Ondřej Hošek 23 Jul '11

23 Jul '11

Greetings, long-time reader, first-time writer here. I've been using ConTeXt for about a year and, until now, been able to solve all my problems using the wiki or the mailing list, so a "keep up the good work!" is certainly in order. ;-) My problem concerns kerning in mkiv, which apparently doesn't work for all sans-serif fonts. It does seem to work for TeX Gyre Heros and Latin Modern Sans, but not, as an example of a font shipped with ConTeXt, DejaVu. Here's a short testcase: \usetypescript[dejavu] \setupbodyfont[dejavu,12pt,rm] \starttext Token (kerned) T{\char"200C}oken (unkerned) {\ss Token (kerned)} {\ss T{\char"200C}oken (unkerned)} \stoptext (U+200C is the "zero width non-joiner", rather useful as an invisible breaker of kerns and ligatures.) Expected behavior: first line "To" kerned, second line "To" not kerned, third line "To" kerned, fourth line "To" not kerned. Differences to expected behavior on my machine (ConTeXt minimals 2011.07.22 01:29): third line "To" not kerned either. Thanks for the assistance in advance! Cheers, ~~ Ondra Hošek

footnotes: is this a bug?
by Thomas A. Schmitz 22 Jul '11

22 Jul '11

Hi all, this is something that has made me wonder: am I doing something wrong here, or is this a bug with footnote placement? Run the attached example, look at the last 2 pages, 5 and 6. On p. 5, the footnotes run off the page area. On p. 6, why is there so much space between text area and footnote area. The reason for this somewhat exotic set-up: our publisher wanted the footnotes of the last page of every chapter to start right after the text, not at the bottom of the page. In the end, I told them I couldn't do it, and they were fine with it. But I still think it should be possible; I've looked into a number of books, and it seems a common layout in the humanities. Maybe someone has a bright idea? (Wolfgang, you answered to this problem 2 weeks ago and suggested having "aftersection={\setupnote[footnote][location=high]}" in \setuphead, but this triggers the same problems). So maybe a bug? All best Thomas \showframe \starttext \dorecurse{21}{Imagine trying to live in a world dominated by dihydrogen oxide, a compound that has no taste or smell and is so viable in its properties that it is generally benign but at other times swiftly lethal.

markdown
by Hans Hagen 22 Jul '11

22 Jul '11

Hi Khaled, I took a look at the lunamark code, and ran it on some (copied) sample. As it was much slower than I'd expected from lpeg I messed around a little and could bring down the runtime on the sample from 2 sec to 0.1 sec. Anyhow, there is room for improvement so I wonder If I should take the code, wrap it up a bit, and make a module so that we can directly process markdown in context. (Of course we then need to keep an eye on how the original develops, if mkdown develops at all.)

Using mycrotypography features with simplefont module and OTF/TTF
by Alexandre Leray 22 Jul '11

22 Jul '11

Dear all, I'm trying to enable protrusion on a text composed with a ttf font (tried otf converted from ttf as well) and using the simplefont module. We have tried different things but did not see any difference in the results. Our context version is 2011.07.20 14:10 The full context code is visible here: http://dpaste.com/574351/ The relevant chunk is this: % USING SIMPLEFONT: FAILS % %\usemodule[simplefonts][protrusion=quality,expansion=quality] %\setmainfont[umepmincho] % USING TYPESCRIPT: FAILS TOO % \starttypescript [serif] [umepmincho] \definefontsynonym [Serif] [name:umepmincho] \stoptypescript \definetypeface [umepmincho] [rm] [serif] [umepmincho] \definefontfeature[default][default][expansion=quality,protrusion=quality] \setupalign[hz,hanging] \setupbodyfont[umepmincho, 10pt] \definebodyfontenvironment[default][x=0.75 ,a=1.5, b=1.75, c=2,d=3.4] % defines higher sizes of fonts Is there a way to make it work? Thanks! Alex
