How to put buttons side by side in interactive menu?
by Verhaag, G.C.H.M. 18 May '11

18 May '11

Hi, I use the well known feature: \startinteractionmenu[right] \but [content] contents \\ \but [sample] sample \\ \but [PreviousJump] back \\ \but [CloseDocument] exit \\ \vfill \stopinteractionmenu to put a menu on the right of the screen of an interactive document. Now I want to use two buttons side by side something like: \but [left] left \but [right] \\ but this doesn't seem to work. I get an !Emergency stop. Anybody any idea how to put the buttons side by side? Regards, Gerard Verhaag P.S. I use ConTeXt ver: 2011.05.16 11:00 MKIV

A module for generic external syntax highlighter
by Aditya Mahajan 18 May '11

18 May '11

Hi all, I have modularized the vim module[1] so that it is easy to reuse components for other external syntax highlight programs. The set up for defining a new external syntax highlighting is done in t-syntax-highlight module, and the set up for defining a new color scheme is done in t-syntax-groups. The vim module simply calls these modules with the relevant setups. These modules also use an experimental coding style for the ConTeXt code. This is based on some discussions that we had on the list earlier. (This style sets the catcode of : to be other; this can break existing ConTeXt code). All modules work with both MkII and MkIV; as a result, some of the things are more complicated than they need to be just for MkIV. I believe that this split will make it easy to add new external programs as syntax highlighters. The external highlighter needs to generate ConTeXt code in a specific format: - Start each new line with \CR{} - Escape all \, {, and }, as \\, \{, and \} - Group each syntax region as follows: \SYN[group-name]{content} The external highlighter should also support a means of specifing the start and stop lines to be highlighted. At the TeX end, a new syntax highlighting module should specify the exact external command to be called, and define color schemes (style and color) for each of the group-name used in the \SYN command in the highlighter. In case anyone is interested in testing a specific external highlighter, let me know. Any other feedback is welcome. Aditya [1]: https://github.com/adityam/filter/tree/dev

Hi all, with the current Context beta ConTeXt ver: 2011.04.13 09:23 MKIV fmt: 2011.4.19 int: english/english and a recent luatex LuaTeX, Version beta-0.66.0-2011041617 (rev 4160) (Win 7 64bit) the externalfigure macro breaks with following message: metapost > loading 'metafun.mp' (experimental metapost version two) metapost > terminal: >> picture !

MK IV new install /Mac OS X
by Matthias Weber 18 May '11

18 May '11

Dear all, I've been trying to install the TeX minimals on a new Mac. While MK II works, not so MK IV. I get the error message MTXrun | unknown script 'context.lua' or 'mtx-context.lua' Here is what I did: Downloaded TeXLive 2010 Then followed the instructions at http://wiki.contextgarden.net/ConTeXt_Minimals/Mac_Installation I did this a few years back without a hitch, so I am wondering what is different now. In any case, in the above instructions, under Configuring ConTeXt, instep 4, the copies file has already the indicated changes in it. I used the same paths as indicated and ran luatools --generate as well as context --make Everything went ok without error messages. I then configured TeXShop as explained. As I said, MKII works fine but MKIV gives the error message. I searched the wiki for it and there seem to be some related reports, but I couldn't find a resolution. Any suggestions? If all fails I'll try to clone an older installation. Matthias

\setuplayout fail to \setupinteractionscreen
by Markus Finke 17 May '11

Hello, how can I get a centered paper of A5 on A4 (with crop marks) for the whole document? A minimal example, only the first page looks correctly: \setuppapersize [A5][A4] \setuplayout [marking=on,location=middle] \showframe \setupinteraction [state=start] \setupinteractionscreen [option=singlesided] \starttext \dorecurse{5}{\input knuth \page} \stoptext

MP spot color in gradient - help!
by Duncan Hothersall 17 May '11

17 May '11

Struggling against a deadline here so apologies for no full sample. I have a gradient fill defined using \startuseMPgraphic{mpos:par:mylearnobj} path p; for i = 1 upto nofmultipars : p := multipars[1] topenlarged 8pt bottomenlarged 8pt leftenlarged 3cm ; color ca ; ca := \MPcolor{greenthirty} ; color cb ; cb := \MPcolor{white} ; sh := define_linear_shade(origin, origin shifted (120mm,0), ca, cb) ; fill p withshade sh ; endfor; \stopuseMPgraphic This works if the colour "greenthirty" is defined as a CMYK colour \definecolor[TAXBgreenthirty][c=.3,m=0,y=.057,k=.069] but, inevitably, my printer wants it defined as a spot ink, and when I do this: \definecolor[PantoneThreeOneFourFive][c=1,m=0,y=.19,k=.23] \definespotcolor[TAXBgreenthirty][PantoneThreeOneFourFive][p=.3] the gradient turns to black instead of green. (The spot colour definition works fine in the rest of the document, just not in the gradient fill.) Could someone possibly let me know if it is even possible to define a gradient using a spot colour, or if I should instead revert to some alternative solution. Thanks, Duncan

This PC emulator is written in Javascript. The emulated hardware consists in: * a 32 bit x86 compatible CPU * a 8259 Programmble Interrupt Controller * a 8254 Programmble Interrupt Timer * a 16450 UART. http://bellard.org/jslinux/tech.html Wow... He is not unkown for me I started time ago to look at tcc http://bellard.org/tcc/ Also his calculations about Pi was (at that time) quite relevant. -- luigi

Re: [NTG-context] about JS(Walk_Field{})
by Jeong Dalyoung 17 May '11

17 May '11

Dear Wolfgang, Your animation module works really fine. It reduces a lot of work to set the fieldstack. I'd like to ask you a few more small things. 1) Is it possible to set the duration time in the case of autoplay? 2) The location of buttons is leftaligned when [menu=yes]. Is it what you want or I did something wrong? 3) What is the meaning of "\start and \stop" in animation-1.tex? 4) In your animation-2.tex, the size of buttons can be controlled by setting foregroundstyle. Then, how to apply it to \startanimation? Thank you. Best regards, Dalyoung

[OT ?] New vi-like editor for Mac
by David Wooten 17 May '11

17 May '11

Hi folks, Thought a few of you might share my interest in a new editor, vico ( http://www.vicoapp.com/ ), in development for the Mac. Vi(m)-like, configurable with nu scripting, nice interface (variable width-fonts in vi!), handles at least some TextMate bundles (like the ConTeXt and LilyPond bundles, at least partially .... to be tested further), handles remote directories via ssh, responsive developer. Not free after full release, if that's a kicker. Dave

Setuplayout bug?
by Verhaag, G.C.H.M. 16 May '11

16 May '11

Hi, The \setuplayout command causes problems I don't understand, sorry! I use the following setup in a screen (\setuppapersize[S6][S6]) document: \setuplayout [header=0cm, topspace=.2cm, backspace=.2cm, margin=0cm, width=fit, footer=1cm, bottomdistance=5pt, bottom=20pt, height=fit] This gives a result as aspected! However adding the setting rightedge=3cm to the layout command, for a menu, yields an unexpected result. Okay, an area on the right of the screen is indeed blank as aspected! But the text of a full page is also shifted downward, and overlaps the text within the footer area, which is quite weird isn't it? I don't grasp this footer problem as indicated above!!!! Any idea what's wrong? Regards, Gerard Verhaag P.S. I use ConTeXt ver: 2011.03.30 11:21 MKIV fmt: 2011.3.30 int: english/english
