How to center \framed on a position?
by Procházka Lukáš Ing. 06 Apr '16

06 Apr '16

Hello, how to center vertically and horizontally a \framed text at the layer origin? I'm not able to figure it out... Here's my code: ---- \setuplayout[page] \definelayer[mybg] \setlayer[mybg] [x=\dimexpr.5\paperwidth\relax,y=\dimexpr.5\paperheight\relax,] {\framed [frame=on,offset=5mm,align={middle,lohi},width=fit,rulewidth=2mm,location=lohi,] {% \setupbodyfont[10mm,sans]% \bf Some text% } } \setupbackgrounds[page][background={mybg}] \starttext Hello, world! \stoptext ---- And - where has the text "Hello, world!" disappeared? Any help would be appreciated... Best regards, Lukas -- Ing.

Consistent random number generation
by Aditya Mahajan 06 Apr '16

06 Apr '16

Hi, Is it possible to generate consistent random numbers across multiple operating systems. For example, consider the following file: math.randomseed(1000) print(math.random()) print(math.random()) print(math.random()) If I process this using texlua, the output on linux and MacOS is different. Is it possible to get consistent output? Rationate: I use randomization to randomize certain paths in metapost. Not all randomly generated paths look okay, so I play around with the seed until I get a good path. But I have to repeat this process everytime I update my distribution and if I compile on different machines. Thanks, Aditya

Square pens and dash pattern
by Aditya Mahajan 06 Apr '16

06 Apr '16

Hi, There appears to be a metapost bug with square pens and dash patterns: \starttext \startMPcode pickup pencircle scaled 1bp; drawarrow origin -- (5cm, 4cm) dashed evenly; pickup pensquare scaled 1bp; drawarrow origin -- (5cm,-4cm) dashed evenly; \stopMPcode \stoptext Note that the second arrow is not dashed at all! This is not due to the thick pen. Aditya

\replaceword in footnotes
by Thomas A. Schmitz 06 Apr '16

06 Apr '16

Hi all, I use replacements to break unwanted ligatures in German text. This works in the text body, but not in footnotes. How can this be achieved in footnotes as well? Example attached! Thanks Thomas \setreplacements [german] \replaceword [german] [Auflage] [Au{fl}age] \mainlanguage [de] \setupbodyfont [termes, 12pt] \starttext flüssig Auflage\footnote{flüssig Auflage} \stoptext

I didn’t look into that docs, but I’d assume, tracking refers to some logging or visualization of spacing. AFAIR ConTeXt can do that very nicely (while I never used it and don’t know how to enable it).

ConTeXt anew-but where?
by klerer＠sxmail.de 05 Apr '16

05 Apr '16

Dear NTG-ConTeXt list members,[a] Excuse me that I will have to send this email in html format. The very format of this email is not meant to offend anyone consciously (even if perceived so). Paragraph beginnings [a] through [e] may lead you the way, instead.[b] A NEW(er) PROBLEM: After I have decided to re-instal ConTeXt because my previous installation (dating from last quarter of 2014) was from some time on un-updatable (maybe some remember a question posted to this list by me in one of the months passed), a folder named "context" in which one can lay down/ find a skript file (.sh) that is the pivot of "any" update to come IS APPARENTLY ABSENT.[c] WHY COULD THAT BE OF INTEREST? ...simply because I wondered throughout this second installation process whether there would be any question which path that very folder should finally have DID SIMPLY NOT SURFACE (the old "context" folder formerly in "/home/myUsername" was discarded).[d] QUESTION: Where, consequently, on a Kubuntu Linux operating system (version LTS 14.04 on a 64bit architecture) was one to look for that folder to be able to eventually perform an update via command line (= bash console) as "http://wiki.contextgarden.net/ConTeXt_Standalone" [Ref-1] describes what the user should do in advance to any update attempt, and thus, following installation? I feel awkward when it comes to that issue as I already asked for an update option earlier.[e] Thank you very much for your precious time.Best regards,Markus Hofstetter

Microtypography in ConTeXt
by Jan Tosovsky 05 Apr '16

05 Apr '16

Dear All, according to http://texdoc.net/texmf-dist/doc/latex/microtype/microtype.pdf pdfTeX offers fine tuning of: (1) Character protrusion (2) Font expansion (3) Tracking (4) Additional kerning (5) Interword spacing AFAIK ConTeXt covers 1+2+(3?). In recent discussion Hans mentioned experimental 'space kerning'. Is it anything related to above features (4)? Are there any plans to cover the rest? Thanks, Jan

Fwd: BachoTeX 2016: deadline extensions
by Mojca Miklavec 05 Apr '16

05 Apr '16

Dear ConTeXters & LuaTeXers, There's no such great opportunity as the wonderful conference BachoTeX in Poland to get your TeX projects done, getting hold of some handcrafting skills (book binding, calligraphy, ...) and to brainstorm your ideas with Hans, Luigi (and many others) while enjoying a cup of coffee, sunbathing or swimming in a lake, or just relaxing around a bonfire. Children and families welcome (even in the conference room). Link: http://www.gust.org.pl/bachotex/2016-en Be warned: the attendance is highly addictive :) Mojca ---------- Forwarded message ---------- From: Jerzy Ludwichowski Dear prospect BachoTeX participants and authors, the deadline for BachoTeX registrations has been extended to the 10th of April 2016, which means that no "late penalty" will be levied. We still do accept paper proposals -- please help to make the conference a success! To whet your appetite please note that among others these are but a few speakers: Norbert Preining (specially from Japan!), Hans Hagen, Willi Egger, Arthur Reutenauer, Ulrik Vieth, Bogus\law Jackowski or Marek Ryćko (no offense intended to others, not mentioned here!) Program details will be posted at the conference page(s) a.s.a.p. Please hurry to register, so we can finalize planning. See you there, for the Organizing Committee (-) Jerzy Ludwichowski

duplex printing and doublesided
by Pablo Rodriguez 04 Apr '16

04 Apr '16

Hi Hans, I have the following sample: \setuppagenumbering[alternative=doublesided] \setupinteractionscreen[option=portrait] \starttext No duplex printing. \page[right] In this document. \stoptext I’m afraid that doublesided alternative disables duplex printing. This would be a good reason to implement the features already asked at https://mailman.ntg.nl/pipermail/ntg-context/2016/084298.html. Many thanks for your help, Pablo -- http://www.ousia.tk
