format generation fails in luat-fio.lua
by Philipp Gesang 31 May '12

31 May '12

Hi all, I hit this bug during “context --make” after today’s update. Can somebody confirm this?

\processmarkdownfile gobbles all starting with % or \
by Procházka Lukáš Ing. - Pontex s. r. o. 31 May '12

31 May '12

Hello, please see the example: ---- \usemodule[markdown] \starttext \startmarkdown AAA -4 % BBB aaa \% bbb \stopmarkdown \processmarkdownfile{t-MD.mkiv} % = This file \stoptext ---- When the t-MD.mkiv is processed by \processmarkdownfile, only "AAA -4" appears from the line "AAA -4 % BBB", so " % BBB" is ignored (skipped). When the percent sign is entered straightly in the \start/stop-markdown scope, it's shown OK. How to enter the percent sign into the file to be processed by \processmarkdownfile so that % is really typeset in the final document? TIA. Best regards, Lukas -- Ing.

how to write two or three single hyphens?
by Jan Pohanka 31 May '12

31 May '12

Hello, describing linux file permissions I would like to write rwx------ As I expected the hyphens are converted to two long dashes (excuse me if I missed the correct name), so I tried something like this rwx{-}{-}{-}{-}{-}{-} or rwx{}-{}-{}-{}-{}-{}- which works in latex, but in context I'm still getting the long dashes. How can I prevent this conversion, please? regards Jan -- Tato zpráva byla vytvořena převratnou poštovní aplikací Opery: http://www.opera.com/mail/

MetaPost transformation
by Troy Henderson 31 May '12

31 May '12

I've encountered a MetaPost issue, and since many MetaPost users also use ConTeXt (and vice-versa), I am posting this question on both lists. The command > show identity rotated 270 yscaled 0.5; outputs (0,0,0,1,-0.5,0) as expected, while the command > show identity transformed (0,0,0,1,-0.5,0); errors with --- ! Missing `)' has been inserted. <to be read again> , l.26 ^^Ishow identity transformed (0,0,0,1, -0.5,0); --- I am using MetaPost 1.504, and the problem seems to be that MetaPost does not like me using the sextuple (0,0,0,1,-0.5,0) directly, but this is the most convenient method for me to describe my transformations. Is this a bug in MetaPost, or am I not allowed to use transformations directly with sextuples? Troy Henderson

Argument to ConTeXt
by Procházka Lukáš Ing. - Pontex s. r. o. 31 May '12

31 May '12

Hello, please see the following calling cases: 1) context.exe t6.mkiv --address=6 2) context.exe t6.2.mkiv --address=6 Content ot both .mkiv is identical - just to print the passed address value: ---- \starttext A \directlua{print("@@@", document.arguments.address)} \stoptext ---- The former case gives expected: " ConTeXt ver: 2012.04.26 22:27 MKIV fmt: 2012.4.30 int: english/english ... @@@ 6 backend > xmp > using file 'c:/ConTeXt/tex/texmf-context/tex/context/base/lpdf-pdx.xml' ... " whilst the latter doesn't: " ConTeXt ver: 2012.04.26 22:27 MKIV fmt: 2012.4.30 int: english/english ... @@@ nil backend > xmp > using file 'c:/ConTeXt/tex/texmf-context/tex/context/base/lpdf-pdx.xml' ... " Is use of more dots in the file name prohibited? - I'm forced to do so, although personally I don't tend to do so... Any way how to solve the latter case (other than to rename the latter file)? TIA. Kind regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

\definetype and ligatures
by Wolfgang Schuster 31 May '12

31 May '12

Hi, are ligatures etc. supposed to be active in verbatim commands? In the default \type command they are only disabled because \tt has “features=none” in the typescripts but since this isn’t the case for serif and sans you get ligatures. \definetype[test][style=\rm] \starttext \type{fi -- ---} \test{fi -- ---} \stoptext Wolfgang

weird pdf bookmarks question
by Taco Hoekwater 31 May '12

31 May '12

Hi all, I have a question about PDF bookmarks. My Document goes like this (heavily simplified): \setupinteraction[state=start] \placebookmarks[chapter,section][chapter,section] \setupinteractionscreen[option=bookmark] \starttext \chapter[item1]{Overview} \startitemize \item[item4] bla \stopitemize \chapter[item2]{Two} Greetings! \chapter[item3]{Three} I don't know \chapter{Four} Oh no. \stoptext Now, what I would really like is if the link in the bookmarks for 'Four' jumps to the first page (where the 'item4' reference target lives) instead of to the fourth page (where the chapter header lives). The question is: is this possible, and if yes, how? To further complicate things, this is an old project that uses mkii, so lua-based solutions are not helpful. Thanks in advance for any pointers, Taco

\setuplayout[location=duplex] not working? (probably since a year)
by Marco Pessotto 31 May '12

31 May '12

Hello there. I'm messing around with imposition schemas and I think I've hit a bug or a dropped feature (but documented in the printed manual). Minimal example: \setuppapersize[A5][A4] \setuplayout[location=duplex] \starttext \dorecurse{20}{ \input knuth } \stoptext As far as I can see, the duplex location is ignored, as the page is always put in the left corner. Am I doing something wrong? The behaviour is the same with the one-year-old ConTeXt from TeXlive2011. -- Marco

alignment in a footer
by Jan Pohanka 31 May '12

31 May '12

Hello, I'm making a template for company documents and we need to have something similar in the footer \framed[frame=off,bottomframe=on,width=broad,align=flushleft]{\ss No part of this document may be reproduced, modified or disclosed to third parties in any form without the prior written permission of COMPANY. This document is copyrighted by COMPANY with all rights reserved.} \startoverlay {\leftaligned{title}} {\midaligned{1/1}} {\rightaligned{\externalfigure[jc_logo_small][width=4cm]}} \stopoverlay Unfortunately I have two problems with code above. I need to have the text and figure in overlay top aligned and also the text in the frame should have the exactly same width as the overlay. How can I achieve this please? best regards Jan -- Tato zpráva byla vytvořena převratnou poštovní aplikací Opery: http://www.opera.com/mail/

You can implement something like what you wanted directly because, just as you can write equations for the parts of a pair, you can also write equations for the parts of a transform: vardef mktransform (expr a,b,c,d,e,f) = save T_; transform T_; xpart T_ = a; ypart T_ = b; xxpart T_ = c; xypart T_ = d; yxpart T_ = e; yypart T_ = f; T_ enddef; After this transform T; T := mktransform (1,2,3,4,5,6); show T; produces: >> (1,2,3,4,5,6) Regards, Dan Daniel H.
