Hello, the command \os turns old-style numbers on. How to turn it off (when being on initially)? TIA. Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

Leave out reference to page if on the same page?
by Gerben Wierda 02 Aug '14

02 Aug '14

Suppose I have this fragment: is shown in \in{figure}[foo] on \at{page}[foo]. \placefigure [] [foo] I would like to leave the fragment “on \at{page}[foo]” out of the text if the figure ends up on the same page as the \at. Is that doable or is this a matter of manual tweaking at the end? G

Blackboard signs for set of rationals (Q) and reals (R)?
by Gerben Wierda 02 Aug '14

02 Aug '14

Just a simple question I could not find the answer for in the docs. What do I need to get the blackboard style (double lines) characters for R (the set of real numbers) and Q (the set of rational numbers) in a ConTeXt document? G

Thanks to you both! I missed the global/local conflict, and then learned a way to avoid double computation; thanks again! John

Lua to Context Table
by John Kitzmiller 01 Aug '14

01 Aug '14

Here is Lua code that prints the first nine fibonacci numbers: local function fib(n) f={1,1} for i=3,9 do f[i]=f[i-1]+f[i-2] end return(f[n]) end for n=1,9 do print(fib(n)) end Here is Context+Lua that prints 3 x 3 table of the first nine natural numbers: \starttext \setupTABLE[each][each][frame=off,align=left,width=4em,height=2em] \startluacode context.bTABLE() for j = 0, 2 do context.bTR() for k = 1, 3 do context.bTD() context(3*j+k) context.eTD() end context.eTR() end context.eTABLE() \stopluacode \stoptext How can these be combined to print a 3 x 3 table of the first nine fibonacci numbers? I have tried a couple of ways to iterate over the lua table f in the most indented line of context, looked at what pertinent threads I could find, the Wiki entries, CLD, and tried Aditya's method from Stack Exchange; I am missing something.

Hyphenatedurl: custom line-break symbol, disable stretching
by Joshua Krämer 01 Aug '14

01 Aug '14

Dear list, I typeset URLs with \hyphenatedurl, and have two questions. (1) Is there a feature available to insert a custom symbol when a line-break occurs, e.g. \hookleftarrow? (2) How can I disable the stretching between characters? I've tried the following without success: \setupurl [space=no] \setupurl [urlspace=no] \unprotect \def\lang_url_space{} \protect Thanks and kind regards, Joshua

Where to find s-edu-01.cld mentioned in Context Lua Documents? I use minimals, just updated, --modules="all" --engine="luatex". Also tried --modules="s-edu-01.cld" as well as Google.

Typesetting file names with ~
by Procházka Lukáš Ing. - Pontex s. r. o. 30 Jul '14

30 Jul '14

Hello, which is the best way to typeset text (aka file names) containing tilde so that the tilde be visible? I guess there is a something like (inline) "verbatim" mode which makes ~ (and maybe % $ etc.) visible... I need to typeset e.g. d:/Lukas/~/abc.def and I'd like avoid "translating" ~ into e.g. \textasciitilde. Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

A bug color in tikz
by Xan 30 Jul '14

30 Jul '14

Hi, It's an annoying bug of TikZ with ConTexT: in some circumstances, the content after a tikzpicture is coloured. I refered it [here](http://www.ntg.nl/pipermail/ntg-context/2014/077374.html), and it's also present in the latest version of the minimals. Anyone could check it if he/she finds a bug. Thanks, Xan.
