Layer vs. overlay
by Procházka Lukáš Ing. - Pontex s. r. o. 16 Jan '13

16 Jan '13

Hello, I need to add a text to the FOREGROUND of the page. - Layers can refer to a page (or its size) and elements in a layer are drawn BELLOW the (normal) page content. - Overlays are drawn ABOVE the (normal) page content and their size is given by an element (often \framed) which uses the overlay. So - I'd need a layer which would overlay the normal page content (like "foreground" or "topmost" layer) or an overlay which would refer to (= its size and position would depend on) the (current) page (instead of e.g. \framed); it should be a somewhat combination of layers & overlays. How to achieve this in ConTeXt? Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

getnameinfo
by Wolfgang Werners-Lucchini 16 Jan '13

16 Jan '13

I have to update LuaTex on a win2k machine. But I get two errors while running mtxrun.exe and texlua.exe resp. via first- setup.bat. There is a call to getnameinfo in WS2_32.dll which is available in winxp and above. Here is an info from ms how to deal with this: "The getnameinfo function was added to the Ws2_32.dll on Windows XP and later. If you want to execute an application using this function on earlier versions of Windows (Windows 2000, Windows NT, and Windows Me/98/95), then you need to include the Ws2tcpip.h file and also include the Wspiapi.h file. When the Wspiapi.h include file is added, the getnameinfo function is defined to the WspiapiGetNameInfo inline function in the Wspiapi.h file. At runtime, the WspiapiGetNameInfo function is implemented in such a way that if the Ws2_32.dll or the Wship6.dll (the file containing getnameinfo in the IPv6 Technology Preview for Windows 2000) does not include getnameinfo, then a version of getnameinfo is implemented inline based on code in the Wspiapi.h header file. This inline code will be used on older Windows platforms that do not natively support the getnameinfo function." Hope this can be done. Wolfgang

Lettrine not Working as Expected
by Malte Stien 16 Jan '13

16 Jan '13

Hello everyone, I have been trying the lettrine module and have come across some unexpected behaviour. I have been following the documentation found here http://modules.contextgarden.net/dl/t-lettrine/doc/context/third/lettrine/l… and have proceeded to make a minimal example: \usemodule[lettrine] \starttext \lettrine[Lines=3]{T}{his is a test} \input knuth \stoptext Unfortunately the output is not quite what (I think) it should be. It appears that the first line is rendered as expected, but that it is followed by a vertical gap---an extraordinary line spacing if you will---that places the second line all the way beneath the 'T', where the forth line would be expected. However, the second and third line are indented the way you would expect, they are just two lines further down as they should. As this may be hard to express, I have attached a small PDF with the result of the above code. Thank you, Malte.

buffers (append)
by Alan BRASLAU 15 Jan '13

15 Jan '13

Hello, In addition to \startbuffer \stopbuffer it would be nice to have \startappendbuffer \stopappendbuffer. I see that the lua function buffer.append() exists but I have not worked-out how to add this functionality cleanly as conTeXt macros. I imagine that this might be quite trivial for our TeX programming experts... (for once, a [useful?] suggestion that in the end will not entail many hours of work? :) Alan

Deactivating Grid-Setting for titles
by "H. Özoguz" 15 Jan '13

15 Jan '13

Hi there, I am setting with grids. Now in classical typographie not all text-elements have to be grid-setted, f.e. titles not. How to deactivate gridsetting for titles? This is relevant, because titles and the distances between a title and the before and the after text ist very important for text-aesthetics. F.e. if I have ++++++++++ Paragraph \section{Blub} \seubsection{blub1} Nextparagraph ++++++++++ I want to deactivate grid-setting after the first paragraph and want to activate it with the beginning of the next. How to do that? Best regards Huseyin

Hi there, I am setting with grids. Can I control the empty lines between a section-titel and a subsection-title? \section{Blabla} \subsection{Blup} I want to have exactly x empty lines between them (zero should be allowed for x, too), how to force that? Best Regards

Problems with contextual kerning
by Georg Duffner 15 Jan '13

15 Jan '13

Hello, In EB Garamond I’ve implemented decomposition for all composed glyphs. For uppercase greek I had to use contextual kerning rules: accents like grave or acute and aspiration marks are placed left of the letter, so the glyph has to be placed more to the right and its advance increased. The code in the feature file looks like this: pos [ Epsilon Eta Iota Rho ]' <79 0 79 0> @grk_tlAcc1; Iota adscriptum needs extra space on the right of the base glyph, so there are position rules for that too: pos Eta' <0 0 200 0> uni0345.cap1; and pos Eta' <79 0 279 0> uni0345.cap1 @grk_tlAcc1; Context (and LuaLaTeX too) doesn’t do the positioning correctly. I’ve prepared a minimal example of uppercase etas. The first row without decomposition, the second decomposed, the third with alternate uni0345.cap1 (iota adscriptum). The first two should look exactly the same: \usemodule[simplefonts] \setmainfont[ebgaramond] \definefontfeature[decomp][ss20=yes] \definefontfeature[iota1][ss20=yes,cv81=1] \starttext ἨἩἪἫἬἭἮἯᾘᾙᾚᾛᾜᾝᾞᾟῌ \par \addff{decomp}ἨἩἪἫἬἭἮἯᾘᾙᾚᾛᾜᾝᾞᾟῌ \par \addff{iota1}ἨἩἪἫἬἭἮἯᾘᾙᾚᾛᾜᾝᾞᾟῌ \par \stoptext I use ss20 for full decomposition because it should be selected by the user explicitly only when needed, while ccmp should be enabled by default. The attached ctx_test.pdf shows its output. The font used can be downloaded at http://georgduffner.at/ebgaramond/fonts/EBGaramond12-Regular.otf. For comparison, there’s a test page at http://georgduffner.at/ebgaramond/etatests.html – current Firefox and Chromium show what is expected. There’s a second testfile at https://github.com/georgd/EB-Garamond/blob/master/tests/context_greektests.… with the complete Unicode block of greek polyphonic characters, its pdf output is attached to this mail too, a comparison html page is at http://georgduffner.at/ebgaramond/greektests.html Best regards, Georg
