Do you know who is the author of this. There is a version number 0.04 and the comment (still in development). I have made some corrections and don't want to do this in the wiki without contacting the author. There should also be a example of usage, maybe yours? Wolfgang

footnote marks fail
by Michael Saunders 13 Apr '10

13 Apr '10

Footnotes are normally marked with superior figures both in the text and before the footnote itself. Context's defaults prevent this, and I can't figure out how to change the defaults. 1. The defaults So that no imagination is necessary, here is a minimal example: \starttext text\footnote{footnote} \stoptext I have to guess what Context is doing. It looks like it's taking the regular numbers from the font, shrinking them somehow and elevating them. It does this in unequal amounts for the marks in text and the marks before footnotes. In both cases, the number is so light it's barely readable. In the case of the mark before the footnote, it's raised much too high. Normal, professional fonts have superior figures in them that are used for footnote marks. It _should_ be possible to use them, that is. All I want to do is turn off the default scaling and raising behavior of Context footnote marks so I can do this, and finally get normal looking footnotes. No doubt, people will object that they don't have my font in the room with them, and it is therefore impossible to think about the problem. So, I repeat myself: all I want to do is turn off the default scaling and raising. 2. My first stab at correcting this. WARNING: I have a font with the opentype features 'sups' and 'numr'. You might not have this font, but it is still possible to think about the problem: the problem is not my font, but Context's defaults. \definefontfeature[su][default][sups=yes]%superior \definefontfeature[nu][default][numr=yes]%numerator \newcommand{\fnstyle}{\switchtobodyfont[12pt]\addff{su}} \setupnote[footnote][numbercommand=\fnstyle,textcommand=\fnstyle\tfa] (Note: my body font is 12pt.) This is as close as I could get to correcting the problem. When I do this, the marks in text look a little too low, too short and much too bold. It looks like Context is still scaling and elevating on its own. The marks before the footnotes are much too large and far, far too high. Context seems to be trying to squeeze them between the lines. This also seems to force extra space between the separate footnotes, even though I have grid on. If I try using numerators instead of superiors (they look the same but are lower), the marks in text look too bold and far too low. The marks before the footnotes are at the right height, but too big. DISCLAIMER: it is not necessary to own my font in order to think about this problem. The issue is the default scaling and raising that Context applies to footnote marks. I want to turn it off.

Re: [NTG-context] Building a guitar chord using MP

Hurray! I've got first draft version of guitar chord building macro.

Typographical Engineering in Context
by Idris Samawi Hamid ادريس سماوي حامد 12 Apr '10

12 Apr '10

[Disclaimer: NOT a joke!] Dear gang, cabal, and knights of the context table, FYI: I am presently working on a book: Typographical Ontology and Engineering: Structured and Automated Authoring in Context It is a book on ConTeXt, but NOT a ConTeXtBook, ConTeXt Companion, or other clone. Rather, it aims to introduce Context as a general tool for typographical and typesetting engineering. Some of the philosophy of book design and layout will be discussed, and it will contain a strong reference to commands etc. NB: MKIV ONLY! The basic outline is I. Ontology and Theory II. Typographical Engineering in Context [including special topics, advanced techniques of luatex, opentype etc] III. A Typographical Engineer's Reference [organization of options and commands, glossary] IV. Appendix: Authoring in Notepad++ [or some other tool] V. Indices So no knowledge or familiarity with TeX is assumed at all. We will cover some advanced topics as well, including introductions to luatex scripting etc I was not planning to announce this for some time yet, but given the buzz around the topic on ConTeXt documentation Hans thought it would be a good moment to introduce this project and to get your feedback. So please use this thread to make suggestions: What would you all like to see covered in the planned book project: Typographical Ontology and Engineering: Structured and Automated Authoring in Context I look forward to your feedback and suggestions! Best wishes Idris -- Professor Idris Samawi Hamid, Editor-in-Chief International Journal of Shi`i Studies Department of Philosophy Colorado State University Fort Collins, CO 80523

Re: [NTG-context] How to define your own math character (MK-IV)
by gummybears 12 Apr '10

12 Apr '10

Hi Hans & Aditya Please be patient as I am not a developer just someone who writes documents. I discovered the integral symbols starting at the double integral are now composed by repeating the normal integral symbol n-times. However in an earlier email I commented that they didn't look right (something to do with setting the displaystyle (I think)) Then I discovered the Asana math font which has "correct" glyphs The missing symbols for math-vfu.lua are Asana math font 0x222B normal integral \int 0x222C double integral \iint 0x222D triple integral \iiint 0x222E contour integral \oint 0x222F surface integral \oiint 0x2230 volume integral \oiiint I also need the space-time integral \iiiint (4 i's) but could not find it in the Asana font Note for the other math stuff the Asana math font does not work like vectors and such. For $\vec{r}, \vec{R}$ the vector symbol is shifted to the right and not aligned above the character (hope this make some sense otherwise forget it for the moment). Kind regards gummybears
