register: spurious space & one more entry level ask
by Vit Zyka 20 Sep '07

20 Sep '07

Dear ConTeXters, there are 3 topics dealing with register (index): 1. [Spurious space] There are entries like \registerpage{index}{,}{5}{2--1-1-0-1-0-0-0--1}{2} in a *.tuo file. Since the definition (core-reg.tex) \def\dosetpageregisterpage#1#2#3#4#5#6% {\doifreglevelelse[#5]% {\dodosetpageregisterpage{#1}{#2}{#3}{#4}{#5}{#6}}% {}} there will be a spurious space between page number like Entry 23 , 67 instead of Entry 23, 67 Solution: \def\dosetpageregisterpage#1#2#3#4#5#6% {\doifreglevelelse[#5]% {\dodosetpageregisterpage{#1}{#2}{#3}{#4}{#5}{#6}}% {}\ignorespaces} Test file: -------------- \starttext Text\index{test}. \page[yes] Paragraph\index{test}. \placeindex \stoptext -------------- 2. [feature request] Current register implementation enable upto three entry level (\index{level 1+level 2+level 3}). My custommer require 4 levels. Please could the entry number be extended? 3. [not important, just for info] Formating of the register entries is not much user friendly. See \hangindent1em in a following definition: \def\dosetpageregisterentrya#1#2% {\flushseenregisterpage \edef\currententrylevel{1}% \global\let\c!entryb\relax \global\let\c!entryc\relax \gdef\c!entrya {\iffirstregisterentry\else\endgraf\fi % new \global\firstregisterpagetrue \hangindent1em\noindent\c!entryreference \dohandlepageregisterentry{#1}{#2}% \global\firstregisterentryfalse \global\firstsubentrytrue \global\firstsubsubentrytrue}} So, when one want the change formating he has to redefine this definition. It is against a ConTeXt spirit. Best Vit

indent and blank question
by frantisek holop 19 Sep '07

19 Sep '07

hi there, i am working on a book format document using: \setupindenting[medium,yes] so the parapgrahps have no whitespace between but the first line of the next paragraph is indented. as is customary, i would like to start a new "part" (lacking a better word) of the same chapter without a title, unrelated to the previous text but not warranting a new chapter. some books put some symbols inbetween these "chapter parts" like three stars or something. if a put a \blank and start a new paragprah, it gets indented. i know i can use \noindent to get what i want, but my question is, is there something more "automatic", a space command which makes the next paragraph unindented or something? or for example if i wanted to put the 3 stars there, could i redefine subject or subsubject to output these _and_ make the next paragprah unindented? -f -- the golden rule: he who has the gold makes the rules.

externalfigure rotation
by Santy, Michael 19 Sep '07

19 Sep '07

Hello, I'm looking to rotate an externalfigure inside of its bounding box in increments of 90 deg. Its real easy with 0 and 180, you can just do: \externalfigure[blah.pdf][width=5.0in, height=2.0in] \rotate[rotation=180]{\externalfigure[blah.pdf][width=5.0in, height=2.0in]} Both commands result with an image that is 5.0in wide and 2.0in tall. But the problem comes when rotating a externalfigure at 90 and 270 degrees (or more generally, anything besides 0 and 180). The rotation is applied to the whole bounding box instead of rotating the picture within a bounding box. The following images will be rendered 2.0in wide and 5.0in tall. \rotate[rotation=90]{\externalfigure[blah.pdf][width=5.0in, height=2.0in]} \rotate[rotation=270]{\externalfigure[blah.pdf][width=5.0in, height=2.0in]} Are there any plans to add support for specify an externalfigure's rotation within its bounding box, similar to this: \externalfigure[blah.pdf][width=5.0in, height=2.0in, rotation=90] Cheers, Mike

> Hi Mike, > > you can control the rotation placement with the location key and the > value middle for location seems to be what you want but the the result > looks to me weird or broken and tried to fix this with the new value > center, you can see the results in small example below. I really appreciate the response, but I'm afraid I don't understand how it addresses my question. I'm not having trouble with the rotation pivot point (i.e., placement), but instead the order in which rotation and scaling are applied to a figure. I am wanting to rotate a figure within a defined bounding box. Mojca was kind enough to point out the following technique. \scale[width=5in, height=2in]{\rotate[rotation=90]{\externalfigure[yourfig]}} It creates a bounding box 5 inches wide and 2 inches tall, rotates the figure 90 degrees and scales the image to fit in the 5x2" bounding box. This approach meets my needs except that the scaling is applied non-isomorphically if both dimensions are specified for the bounding box. I'm now trying to figure out how to optionally scale the image to fit the bounding box while keeping the same aspect ratio. Any thoughts? Cheers, Mike

Re: [NTG-context] waiting for mswincontext
by Vyatcheslav Yatskovsky 19 Sep '07

19 Sep '07

Thank you, Hans and Mojca, for replies. The story started in Septemper, 10, when I updated cont-tmf files for my mswincontext. I did it many times (once there was new update available) but this time I'm gone into trouble. Context started producing broken pdfs for every document with third-party font. I spent many days in trying hard to fix the issue, but nothing was helpful. I was suggested many ideas from the community, until Hans and Taco noticed that "the latest cont-tmf is not in sync with binaries"! How could I ever know that, if these files were posted on current CONTEXT distribution page? My further attempts to update luatex binary alone did not succeed. I was very angry. Now I wait till Owners "regenerate the big things" and I can get proven worked version for Windows. Hope it will be soon. -- Best regards, Vyatcheslav Yatskovsky

"Best Wiki Contributor" & "Best Garden Design": competition & call for sponsors
by Mojca Miklavec 18 Sep '07

18 Sep '07

Dear ConTeXt-ers, I've been thinking for a long time (even before the first ConTeXt user meeting) to organize a little competition to: - promote more wiki/texshow contributions - renew the complete garden design I'm ready to provide the first prize: - free participation at the ConTeXt conference (Bohinj, sLOVEnija, 20.-25. August 2008) - and perhaps TeX user groups could offer one-year membership for some? But now I need: - your ideas and opinions about other prizes and rules - any sponsors / companies who are willing to donate other prizes *** CALL FOR SPONSORS *** If you're working in a company which works with ConTeXt, and you would be ready to help sponsoring that competition by providing prizes for best contributors/designers or for Patrick's work on the garden, please let me know. We could put logo of your company on the garden page(s) and announce that you have helped us. The details could/should be negotiated later, but please let me just know about it if anyone is interested in it ... (If anyone is interested in looking for sponsors, you're welcome as well.) *** BEST GARDEN DESIGN *** We have: wiki: - http://wiki.contextgarden.net source browser: - http://source.contextgarden.net texshow: - http://texshow.contextgarden.net mail archive (not really to be considered for redesign): - http://archive.contextgarden.net context live: - http://live.contextgarden.net modules and articles: - http://modules.contextgarden.net & http://articles.contextgarden.net download area (not so critical for redesigning): - http://dl.contextgarden.ne meeting page (unfinished and not-yet-announced): - http://meeting.contextgarden.net google custom search: - try to put some search string in the second box on the left on wiki Patrick did a great job provide all the functionality on the garden, but we would like to provide some nice and consistent design for all of these modules. Patrick could probably apply the design by himself (or someone could help him), so the most important thing would be: find color & image combinations which would look nice on all modules and promote ConTeXt. My first idea was to offer a free context conference to the "best wiki contributor". Hans suggests the same prize for best garden design. However: - to have one or to have two such prizes doesn't make sooo big difference that this would be unaffordable, but I still cannot afford to provide unlimited free conference fees before I know if I will be able to get enough local sponsors to cover all the costs - the designer could be just anyone, not necessary interested in ConTeXt, and not necessary interested in comming to the ConTeXt conference at all To determine the winner, we could post all the submissions to the mailing list and ask for general opinions + have a jury (Hans, Taco, Patrick + some other volunteers/professional designers). I would also suggest that someone would make a poster asking for contributors, which could theoretically be hung up even on public places (I can imagine hanging one at our facult for design for example). My questions: - what do you think the most appropriate prize should be? - how long should we wait? - what to do if we don't find a suitable design? - etc. etc. *** BEST WIKI CONTRIBUTOR *** I'm looking for your ideas here. We certainly need: - more, better and better organized contents on the garden - basically the whole texshow in empty - new test files The problem is that: - texshow has problems (problems parsing the strings, no authentification, no nice overview of modifications, etc.) - texshow needs better support for common attributes (think of style=bold|slanted|italic|... which has the same arguments on more places) - there should be an easier way to submit and test testcases than the current contexttest project on supelec We should support continuos work. For example by announcing best monthly contributor, and also to make the job of the jury easier (whoever the jury would be). Other questions: - what if there will be noone to deserve the prize? - what if there will be three people with approximately the same big efforts? (I don't fear that, but we should write some basic rules to avoid problems later) - what if that person won't be able to attend the meeting? The wiki competition will probably close in June. I don't know about the other one. ++++++++++++++++++++ I'm simply looking for ideas at the moment, I will announce the competition when I will have a more clear idea what exactly to announce. Anyone who would like to help "organizing" the cometition: you're welcome to help! Mojca

\MPcolor bug with LuaTeX
by Wolfgang Schuster 18 Sep '07

18 Sep '07

Hi, colors defined in gray values give a inverted output in MetaPost with the \MPcolor macro. The output in the text is fine and the red and cyan circles in the MetaPost graphics are also correct but the gray circle has the value s=0.1 and not s=.9 as defined in the colo-rgb file. \setupcolors[state=start] \starttext \color[gray]{Gray} \color[red]{Red} \color[cyan]{Cyan} \startMPpage fill fullcircle scaled 4cm ; fill fullcircle scaled 4cm shifted (5cm,0) withcolor \MPcolor{gray} ; fill fullcircle scaled 4cm shifted (2*5cm,0) withcolor \MPcolor{red} ; fill fullcircle scaled 4cm shifted (3*5cm,0) withcolor \MPcolor{cyan} ; \stopMPpage \stoptext Wolfgang

placing movies
by Hans van der Meer 18 Sep '07

18 Sep '07

Placing a movie with the following code places the static overlay a bit (too far) to the right, spilling it on the right side out of the frame: \useexternalrendering[sharkfilm][video/quicktime][shark.mp4] \defineoverlay [shark][{\externalfigure[shark-film][width=\overlaywidth,type=jpg]}] \starttext ... \midaligned{%\framed[offset=0pt, strut=no, background= {foreground,shark}]% {\placerenderingwindow[movie][sharkfilm]}}% Is there some spurious space in the code? Perhaps a missing % at the end of a line? I could not spot the culprit in the code, but I might have been looking in the wrong places. Then as an additional question: When running the movie a thin white frame line appears around it. I find it annoying but did not find out how to get rid of it. Nor have I been able to change the background color locally (when leaving out the external figure in the overlay) or get rid of the text "Screen" that appears. I found a macro \setuprenderingwindow but did not find out about the settings it understands. Can someone enlighten me? Hans van der Meer

section title: alignment
by Jörg Hagmann 18 Sep '07

18 Sep '07

Dear list members, My section titles have a gray background of textwidth, as follows: \def\SectionCommand#1#2{\framed[frame=off,width=\textwidth,% align=right,background=color,backgroundcolor=lightgray]{#1\quad#2}} \setuphead[section][command=\SectionCommand,numbercolor=red] That works, except when section titles are longer than textwidth: in that case, the second line is aligned with the number, not the text. How can I get correct alignment? I tried to include \starttabulate \NC #1 \NC #2 \NC\NR \stoptabulate in SectionCommand, but then the background extends too much above and below. I'm sure there is an easy solution? Thanks a lot, Jörg Minimal example: \setupcolors[state=start] \def\SectionCommand#1#2{\framed[frame=off,width=\textwidth,% align=right,background=color,backgroundcolor=lightgray]{#1\quad#2}} \setuphead[section][command=\SectionCommand,numbercolor=red] \starttext \section{A very long title, longer than the width of the text and therefore needing a second line} \stoptext

But something I played with once upon a time for much the same purpose. You should take a look at Jonathan Fine's TeX daemon project texd (http://sourceforge.net/projects/texd) if you haven't already - it runs as a pipe (unix) and only loads formats once; it would take a little bit work to get it going reliably with ConTeXt, especially to do so in a way that is easily updated when a new ConTeXt is released, and I'm not sure if Jonathan is still actively working on the project. But it demonstrates an effective approach, which works with Plain (and LaTeX I think). Duncan
