Downloading ConTeXt standalone alternatively
by Jan Tosovsky 07 Apr '16

07 Apr '16

Dear All, I've tried to install ConTeXt at work, but it failed because of blocked 873 port used by rsync. Our admins aren't going to open that port in foreseeable future. I don't have any computer outside the firewall to tunnel the port using 'nc' program as described at http://wiki.contextgarden.net/ConTeXt_Standalone - and I am on Windows so I don't have 'ssh' either. Looking into the first-setup.bat and especially to mtx-update.lua all files seem to be picked up on demand and there isn't any repository for ConTeXt Standalone I could download directly (that syncing is not crucial now). Is there more efficient way than packing my home context folder and copying & unpacking it in my work? Thanks, Jan

MPinstance
by dr. Hans van der Meer 07 Apr '16

07 Apr '16

I do not understand the info in the ConTeXt wiki on setupMPinstance. The syntax is specified as \setupMPinstance[...][...,...=...,...0 [...] name format metafun mpost etc. I read this as: in the first argument one can specify a name presumably a name specified on \defineMPinstance. in the second argument [format=metafun] specifies the format. But then the example under Usage gives: \setupMPinstance[metafun][...] Why metafun in the first instead of the second argument as implied in the syntax description? I get confused here. Also in the description \startMPextensions and \startMPinitializations are mentioned, but their descriptions are missing from the list given in the page MetaPost in ConTeXt. How are these described and what is the specific purpose of \startMPextensions compared to \startMPinitializations? What is the recommended use for them? Hans van der Meer

Hi Mojca, is the server working again? I just wanted to mention that the garden hasn't picked up the latest beta yet, so if it's online again, maybe the syncing process needs to be triggered? All best Thomas

combining itemize and starttabulate
by Jan Willem Flamma 07 Apr '16

07 Apr '16

Dear members, The following combination of itemize and starttabulate is numbered from 'd. to f.' instead of from 'a. to c.' \starttext \startitemize[a] \starttabulate[|l|p|] \item \NC column1 \NC column2 \NC \NR \item \NC column1 \NC column2 \NC \NR \item \NC column1 \NC column2 \NC \NR \stoptabulate \stopitemize \stoptext I'm unable to figure out why this occurs and also how to get the following desired result: a. tekst tekst b. tekst tekst c. tekst tekst Kind regards, Jan Willem

On LuaTeX beta-0.95.0
by luigi scarso 07 Apr '16

07 Apr '16

Hi all, we have put beta-0.95.0 on the luatex svn already from while, but the tag is not frozen because: 1) Hans is working on the manual, 2) I keep source/ in sync with TeXLive (kpathsea files etc ), 3) we fix bugs, of course --- the building process not always goes well on every the platforms that we support. The initial plan was to put 0.90.0 for TeXLive, but now we are pretty confident that 0.95.0 is ok, and we have no plan to touch the codebase in source/ (bug fixing apart). (@Karl: I can keep Master/texmf-dist/doc/luatex/base in sync, if it's ok for you) For those that build from source: A. Kakuto keeps the TeXLive repo aligned with the luatex repo, assuring that the windows binaries are ok. It's clear that, having two repos with the same program, is a bit hard to decide which program is the latest one, so when I import from TeXLive in the commit message I specify the revision (e.g. "sync with TL rev. 40299." ); in the luatex repo, trunk and tags/beta-0.95.0 are always aligned, always first trunk and immediately after beta-0.95.0. I found more simple to have both the repos (texlive and luatex) on my machine, but it's my choice. Unfortunately currently the contextgarden server has some problems, and perhaps not all context users have the latest luatex --- not a big problen, we are working on this. The formal announcement of Luatex 0.95.0 very likely will be when the TeXLive is frozen. around 4may. -- luigi

They are mentioning luatex, while those features require ConTeXt 'preprocessing'. i didn't read that document but i assume it refers to latex which for sure will have some way to set up these feaures; i don't know about plain support in context protrusion and expansion is supported in mkii (pdftex) and mkiv (luatex) .. in mkiv there is a bit more control there is no preprocessing involved (these two features are just part of the par builder) extra kerning and so is done by manipulating node lists (so not an engine feature but a context one) >> i don't think that there are typographical advantages of using pdftex >> over luatex (at least not with context) > > Great, thanks!

Just curious why not mentioned as supported on the title page. what title page? anyway, one can kick in extra font features to deal with kerns (although when a font is that bad i'd use another font) >> 5 - it being a rather core tex feature, normal interword spacing is >> supported > > This seems to be a standard glue with plus/minus value.

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
