I tried the following: \setupfootnotes[textcommand=,numbercommand=,style=,bodyfont=] \starttext text1\footnote{1footnote} \stoptext and it almost works. The third and fourth '1' look the same, but the first and second '1' (those in the text) are different. The second is on the baseline, but it has been scaled much smaller than the first. I want to turn off even this scaling. My eventual plan is to use my sups for this (they seem to work fine for me), but for now I'd be content to turn the automatic scaling off. By the way, of these four keys (textcommand, numbercommand, style, bodyfont), it's not at all clear to me what each is supposed to control.

I'm trying to follow http://wiki.contextgarden.net/rsfs to get a script L in math mode (to denote Laplace Transform) but to no avail.

What happened with bold math?

Hello, What happened with bold math? \mathbf does not have any effect. \setupbodyfont[mscore,rm,12pt] \starttext $${\mathbf x}'(t) = f({\mathbf x}(t), {\mathbf u}(t), t)$$ \stoptext Regards, Vyatcheslav

Sebastien Mengin: > Sorry, a bit off topic, but: is \setupfootnotes[] a synonym for > \setupnote[footnote][] ? Besides \setupfootnotes[] and \setupnote[footnote][] there are: \setupenumerations[footnote][] and \setupfootnotedefinition[] and maybe more. I have no idea how they are related or even how to find out the difference.

Internet archive integration into bibliography
by Matija Šuklje 13 Apr '10

13 Apr '10

Hullo, lately I got an great idea(TM) concerning citing internet sources. \\ Initial problem: the internet is ever changing, what says on a page today, might not be there tomorrow and in ten years' time the page might not exist at all. \\ Solution so far: just smack the date (and time) next to the link. I've seen that often and my faculty expects this from me as well. \\ Problem with the solution so far: it doesn't solve anything really. \\ Solution(TM): along with the URL and date, add the Internet Archive's link from that time next to it as well. The ‘Solution(TM)’ is a bit tedious though, so it'd be great if ConTeXt could automate this process a bit. What I'm thinking is, if ConTeXt could take the URL and date stored in the bibliography (.bbl) and combine it together to form a URL of the Internet Archive's Wayback Machine to point to that particular page at that particular time. In the document's bibliography then it could be rendered something like this: Wikipedia: ConTeXt; http://en.wikipedia.org/wiki/ConTeXt; as seen on the day: 12th of April 2010 at 13:45 With "http://en.wikipedia.org/wiki/ConTeXt" being a hyperlink to just that and "12th of April 2010" being a hyperlink to http://web.archive.org/web/20100412134500/en.wikipedia.org/wiki/ConTeXt Note: using any date and time works OK with the archive.org, since if the date doesn't exist in its database, it falls back to the last archived site before the date requested. What do you think? Would this make sense? If so, should we enable it by default? Cheers, Matija -- gsm: +386 41 849 552 www: http://matija.suklje.name xmpp: matija.suklje(a)gabbler.org

Custom verb-c inside my working directory
by Nicola 13 Apr '10

13 Apr '10

Hi, in MKII the following code produces the wrong result ('* x;') \usemodule[verb-c] \starttext \startC int* x; \stopC \stoptext I know that I should use \definetyping[C][option=C] instead of \usemodule. The fact is, what I am actually loading is a customized verb-c file that I've put inside my working directory (and I have also renamed). How to reconcile the use of \definetyping with a local file?

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.
