metafun manual: Typo on page 382, section 9.3 drawing functions
by Paul Menzel 12 Oct '11

12 Oct '11

Dear ConTeXt folks, I am sorry to bother you with these kind of messages. On page 382 of the Metafun manual [1] (Fr 08 Okt 2010 13:44:26 CEST) it should be In this case the pairs (log(x), x) and … so (log(x), x) instead of (x, x). Thanks, Paul [1] http://www.pragma-ade.com/general/manuals/metafun-s.pdf

Solution to a "superscript" problem?
by Otso Helenius 12 Oct '11

12 Oct '11

Hello, I've been trying to come up with a few methods to add definitions to text with the help of the metafun and context manuals. The first method adds the definition as sort of a "superscript" on top of the word, and the second one marks multiple words with a curly bracket and adds the definition on top of the tip of the bracket. Here is the (ugly and hackish) code: \startuniqueMPgraphic{defline} path p; p:=(0,0)..controls (0,1) and (1,1)..(1,1)--(6,1)..controls(7,1) and (7,1)..(7,2)--(7,2)..controls(7,1) and (7,1)..(8,1)--(13,1)..controls(13,1) and (14,1)..(14,0); draw (0,0)--(0,12pt) withcolor white; draw p xscaled (\overlaywidth/15) yscaled 5 shifted (0,9mm) withpen pencircle scaled 0.25mm withcolor red; \stopuniqueMPgraphic \defineoverlay[curlybracket][\includeMPgraphic{defline}] \def\sentencedef[#1][#2]{\setbox\scratchbox=\hbox{#2}\hbox to \the\wd\scratchbox{\cbox{\hbox{\tfxx\color[red] #1}\\\hbox{\framed[background=curlybracket,frame=off]{#2}}}}} \def\worddef[#1][#2]{\setbox\scratchbox=\hbox{#2}\hbox to \the\wd\scratchbox{\cbox{\hbox{\rotate[rotation=25]{\tfxx\color[red] #1}}\\\hbox{#2}}}} \starttext \hbox{\worddef[def1][Lorem] ipsum \worddef[def2][dolor] sit \worddef[def3][amet] consectetur \worddef[def4][adipiscing] elit.} \hbox{\sentencedef[def5][Lorem ipsum] dolor sit \sentencedef[def6][amet consectetur] adipiscing elit.} \stoptext I haven't figured a way to add the curly bracket graphic neatly nor position the definition correctly on top of it. I would be very interested in any advice regarding these two functions and how to rewrite both of them in a more elegant way.

beta
by Hans Hagen 12 Oct '11

12 Oct '11

Hi, I uploaded a new beta. There are a few new things and some changes: - The flow chart module has been rewritten for mkiv and cf Wili it does a decent job so I've replaced the old one. This is the one that can be extended (discussed at the context conference). - I'm rewriting stepcharts (something I need myself) but that's work in progress. Here the functionality will change a bit (no problem as I never noticed any other usage). The manual will also be updated. == There is an experimental new s-fnt-35.mkiv module that can be used as: \usemodule[fnt-35,art-01] \setupbodyfont [cambria] \starttext \ctxlua{moduledata.fonts.show_a_lot("Cambria")} \stoptext It probably needs to be improved. Users are welcome to submit additional (language related) sample alphabets etc. It might also become an option for mtx-fonts.lua == There has been a change in storing positional info in the tuc file. No big deal, just another format. == There has been a fix in otf contextual stuff ... for Idris (so that he can finish the context book sooner). == There are some new commands: \startdocument and \stopdocument. Copied from mag-1101: \starttyping \startdocument[settings] structured content \stopdocument \stoptyping The settings are key|/|value pairs and the values can be retrieved using: \starttyping \documentvariable{key} \stoptyping You can set \type {before} and \type {after} parameters and by default these are set up as follows: \starttyping \setvariables [document] [before=\directsetup{document:start}, after=\directsetup{document:stop}] \stoptyping You can for instance define these setups to generate a title page (using document variables) and a colophon page. In the future more functionality might be added. == Yet another new feature is automatic italic correction. There will be an article about it (first version ready), maybe in the conference proceedings as it's a follow up on the conference. Quick howto: \definefontfeature[default][default][itlc=yes] It is enabled with: \setupitaliccorrection[always] % or 'text' or 'none' Or (bit more efficient): \setupitaliccorrection[always,global] or even: \definefontfeature[default][default][itlc=yes,notextitalics=yes] to get rid of \/ too. (we might opt for \/ being just /). Thomas and I will play with additional functonality (range support for fonts that have somewhat italic properties like greek). == Of course there are a couple of patches and for sure some new bugs (or missing files).

Lucida hangs (?) on latest beta
by Mari Voipio 12 Oct '11

12 Oct '11

Hello! Encouraged by the recent User Meeting, I'm experimenting with sans serif fonts, trying to find something that I could use all over our documents (European languages) and that would be acceptable to the design people. One of the possibilities would be Lucida, but I'm not having much success with it... First I tried with the wiki, <http://wiki.contextgarden.net/Lucida>. The lucida.zip downloads and extracts nicely, but does not contain any .pfb files, so so much for that. Then I took a leap of faith and just put \setupbodyfont[lucida] in the setup area of my file and something is definitely happening, but then the process hangs. I retried with just ============== \setupbodyfont[lucida] \starttext \chapter{Testing Lucida} \input knuth \stoptext ============== Same result... The whole log is in the end of this message, but I suspect this is the essential part (which SciTe also marks with red): fonts > defining > font with asked name 'lbl' is not found using lookup 'file' fonts > virtual math > loading font lucidamath subfont 12 with name file:lbl.afm at 458752 is skipped, not found !

margin notes
by Meer, H. van der 11 Oct '11

11 Oct '11

It seems that margin notes when called from inside \startcombination..\stopcombination do not reach the margin of the paper. Instead they use a margin inside the combination. Is that as intended or unavoidable? It was my objective to have them at the edge of the paper. See minimal example below. % Testing margin notes from inside combinations. % Margin notes do not leave the combinations box. \setuppapersize[A6][A6] \starttext \setupcombinations[location=middle] test\crlf \startcombination[2*1] {abcdefg\inright{m1}}{l1} {abcdefg\inright{m2}}{l2} \stopcombination \crlf \stoptext
