inside halign
by Hans van der Meer 27 Jun '06

27 Jun '06

This works: \def\dodotablexrule[#1][#2]{\noalign{\color[#2]{\hrule height#1 depth \z@}}} But doing inside halign (tables) things like: \def\tablexrule{\dodoubleargument\dotablexrule} \def\dotablexrule[#1][#2]{% \doifemptyelse{#2}% {\dodotablexrule[#1][\@@tbxframecolor]}% {\dodotablexrule[#1][#2]}% } \def\dodotablexrule[#1][#2]{\noalign{\color[#2]{\hrule height#1 depth \z@}}} I get the error: ! Misplaced \noalign. \dodotablexrule [#1][#2]->\noalign {\color [#2]{\hrule height#1 depth \z@ }} I get the impression that none if these argument related stuff works inside the halign template. Is there a remedy? Or do I just have to give up hope using a unified macro and will have to resort to separate macro's for default/chosen parameters? Hans van der Meer

table splitting in columns
by Henning Hraban Ramm 27 Jun '06

27 Jun '06

this used to work but doesn't since the (my) last update: \starttext \setupTABLE[split=repeat, frame=off] \setupTABLE[c][1][align=right] \setupTABLE[c][2][align=left, style=bf, width=4em] \startcolumns[n=2, balance=no] \bTABLE \bTABLEhead \bTR\bTD\bf Verzeichnis \eTD\bTD\hbox{Dateien}\eTD\eTR \eTABLEhead \bTABLEbody \dorecurse{100}{\bTR\bTD Folder\eTD\bTD 1\eTD\eTR} \eTABLEbody \eTABLE \stopcolumns \stoptext Instead of a table that flows in columns, it breaks only in pages.

Clipping again
by David Arnold 27 Jun '06

27 Jun '06

Hi, I confess I got some earlier advice on this issue, but I've never been able to apply it to find a resolution. In the buffer that follows, I define a clipping box: % clipping path path cpath; cpath:=(-5,-5)--(5,-5)--(5,5)--(-5,5)--cycle; cpath:=cpath scaled 1u; A function is created and scaled: % scale and draw graph P:=P scaled u; draw P withcolor blue; The picture is clipped and saved: % clip and save current picture picture pic; clip currentpicture to cpath; pic:=currentpicture; Then it is redrawn later. % redraw line draw pic; Unfortunately, even though this works, mathematicians really want arrows at each end of the graph. Easy enough to do with drawdblarrow P withcolor blue, but the arrows then get clipped. What I really need is to adapt the code below so that my function is clipped to the boundary box, but then redrawn with arrows at each end of it. If anyone can adjust my code to do that, it would be much appreciated, and it would break down a barrier I've faced for years with metapost coding. Note that I've tried some stuff with cutbefore and cutafter with some success. But I should remark that the code below is generated by a perl script and some special coding we've set up to generate these graphics on the fly for student quizzes. This is not a situation where I can tweak an individual plot or two. Rather, our script might generate 100 sets of the code below, all with different parameters. So this magnifies the problem. Again, any ideas would be greatly appreciated. \startbuffer numeric w,h; w=4cm;h=4cm; % inititialize numerator and denominator of the slope of f numeric a; a=2; % initialize choice of function numeric choice; choice=1; % initialize type of reflection numeric reflect; reflect=2; % define linear function f vardef f(expr x)= a*x*x enddef; % define linear function g vardef g(expr x)= a*abs(x) enddef; % define linear function h vardef h(expr x)= a*x*(x-2)*(x+2)/2 enddef; % define paths for functions f, g, and h, respectively path P, F, G, H; F:=(-5,f(-5)); for x=-5 step .1 until 5: F:=F--(x,f(x)); endfor; G:=(-5,g(-5)); for x=-5 step .1 until 5: G:=G--(x,g(x)); endfor; H:=(-5,h(-5)); for x=-5 step .1 until 5: H:=H--(x,h(x)); endfor; % choose the function to use, f, g, or h if (choice=1): P:=F; elseif (choice=2): P:=G; else: P:=H; fi; % choose the type of reflection if (reflect=1): P:=P; elseif (reflect=2): P:=P reflectedabout((0,0),(1,1)); elseif (reflect=3): P:=P reflectedabout((0,0),(1,-1)); else: P:=P reflectedabout((-1,0),(1,0)); fi; % initialize scale numeric u; 10u=w; % scale and draw graph P:=P scaled u; draw P withcolor blue; % clipping path path cpath; cpath:=(-5,-5)--(5,-5)--(5,5)--(-5,5)--cycle; cpath:=cpath scaled 1u; % clip and save current picture picture pic; clip currentpicture to cpath; pic:=currentpicture; % erase currentpicture currentpicture:=nullpicture; % draw grid for k=-5u step 1u until 5u: draw (-5u,k)--(5u,k) withcolor mygridcolor; draw (k,-5u)--(k,5u) withcolor mygridcolor; endfor; % draw axes drawarrow (-5u,0)--(5u,0); drawarrow (0,-5u)--(0,5u); % label axes label.rt(btex $x$ etex, (5.2u,0)); label.top(btex $y$ etex, (0,5.2.u)); label.bot(btex $5$ etex, (5u,0)); label.lft(btex $5$ etex, (0,5u)); % redraw line draw pic; % draw vertical line test numeric xvert; if (reflect=3): xvert:=-1; else: xvert:=1; fi; % vertical line path vert; vert:=(xvert,-5)--(xvert,5); vert:=vert scaled u; pickup pencircle scaled 2pt; drawdblarrow vert withcolor red; pickup defaultpen; \stopbuffer

I'll update m-gamma soon so > this will be part of the distro if Hans accepts-) I'm very grateful for all the effort on this. I had some trouble installing the new ConTeXt beta to test it at the weekend and spent most of Sunday trying to understand why... But at least I am now in a position to be a tester of the new filter sequences together with the new beta. My revised test files are again at http://www.capdm.com/public/context/figtest.tex and http://www.capdm.com/public/context/figtest.pdf these were regenrated this morning with the latest versions of everything. Please note that I had to remove the \isolateseparators in order to see my alternative "-" separator; with \isolateseparators specified the dot stayed resolutely in place. But the great news is that this also makes the figure reference work, which is fantastic. Note that there is now no need for \reversesectionnumberstrue. Idris, I pasted your maths stuff into the preamble and the test content as well; is this what you expected to see from your test? I wasn't sure, but it looks good to me. Thanks again. Happy to test further for anyone/anything. Duncan

Hans, in Friday's beta, core-sec.tex line 767 has \edef\levelstring{=\flistsectionseparator\@@filternumberpart[#1]\sectionseparator}% which fails not knowing what \flistsectionseparator is. Reverting to \edef\levelstring{=\sectionseparator\@@filternumberpart[#1]\sectionseparator}% works but may not be the intended effect. Duncan

INstall minimal context system.
by John R. Culleton 26 Jun '06

26 Jun '06

I downloaded the justtex.zip and the context-linux.zip files into a work directory /usr/local/cont and unzipped them. Then I cd to the tex directory under that work directory. I made the the setuptex file executable and executed it with no apparent effect. Then I changed the path to point to /usr/local/cont/tex/texmf-linux/bin and ran mktexlsr. It followed the new path. I ran texexec --make --alone and it seemed to be successful. Ran mktexlsr again. Then I ran a test program in another directory. It could not find cont-en.fmt. In fact this file or anything similar to this file does not exist in this tree, although it existed in my previous tetex tree and exists in my texlive tree. How do I create and/or download this file? -- John Culleton

continuous numbering of subsection
by Ulf Martin 26 Jun '06

26 Jun '06

Dear ConTeXt Experts I am still sometimes confused about how to set up simple things... I want to have a subsection level head type ("topic") with a numbering that runs undependently from the section numbering, like so: 1. First Topic ... I. Section One ... 2. Second Topic ... 3. Third Topic ... 4. Fourth Topic ... II. Section Two 5. Fifth Topic ... 6. Sixth Topic ... III. Section Three ... And so on. ConTeXtgarden, the manual, etc. show in great detail how to set up the /appearence/ of head parts (incl. numbercommand), but I cannot find an explanation of the handling of the LaTeX equivalent to counters (their definition, incrementing, resetting, etc.). The explanation of \setupheadnumber in the manual (p. 172) is quite obscure to me -- how do I specify that I do not want higher levels of head to reset my numbering? Thank you! Ulf Martin

All, We are currently using this as one of our environment files: \definehead[unnumberedsubsection][subsection] \setuphead[unnumberedsubsection][number=no,incrementnumber=no] \defineenumeration[questions][location=serried,text=\blank] \setupenumerations[questions][before={\page[yes]\unnumberedsubsection {Exercises}\startcolumns[n=2]},after=\stopcolumns,number=no] \defineenumeration[answers][location=serried,text=\blank] \setupenumerations[answers][before={\unnumberedsubsection{Answers} \startcolumns[n=2]},after=\stopcolumns,number=no] \def\placeanswers{\startanswers\doifmodeelse{short}{\selectblocks [shortanswer][criterium=section]}{\selectblocks[longanswer] [criterium=section]}\stopanswers} \defineenumeration[question][location=inleft,text={\color[heavygreen] \bgroup}] \setupenumerations [question] [location=inleft, text={\color[heavygreen]\bgroup}, stopper={.\egroup}, way=bysection, sectionnumber=no] \defineenumeration[subquestion][location=hanging,text={\color [heavygreen]\bgroup},conversion=characters] \setupenumerations[subquestion][stopper={.\egroup}] \defineenumeration[answer][location=inleft,text={\color[heavygreen] \bgroup}] \setupenumerations [answer] [location=inleft, text={\color[heavygreen]\bgroup}, stopper={.\egroup}, way=bysection, sectionnumber=no] \defineenumeration[subanswer][location=hanging,text={\color [heavygreen]\bgroup},conversion=characters] \setupenumerations[subanswer][stopper={.\egroup}] \defineblock[question,shortanswer,longanswer] \hideblocks[shortanswer,longanswer] Then we do something like: \beginquestion \starquestion Yada, yada, yada. \startsubquestion one part \stopsubquestion \startsubquestion part a \stopsubquestion \startsubquestion part b \stopsubquestion \stopquestion \endquestion Then we have some answers. \beginlonganswer \startanswer \startsubanswer part a \stopsubanswer \startsubanswer part b \stopsubanswer \stopanswer \endlonganswer I'd like to set it up so we could "hide" some subanswers. Any suggestions?

Hi otp lovers, i managed to get this number stuff running (i.e. bypass the otp messing up numbers): i'm uploading a beta beware, there is no need to setup separators, and no need to reverse numbers! \def\ArabicUTF {\ArabicDirGlobal \usefiltersequence[UTFArabic]% \switchtobodyfont[omarb]% \isolateseparators} % will handle separators of course you should not expect proper kerning when isolation is used with latin things like this actually need some advanced control (special otp's for difference situations, depending on what one's dealing with, then to be hooked into the code at the right place, which is tricky since it may get lost later one etc etc) still messed up: math display formulas, strange number reversion and swapping l/r [since omega has bugs with math i'm not sure what is the reason] maybe duncan/idris/taco have an idea Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Iwona Heavy and Math
by Aditya Mahajan 25 Jun '06

25 Jun '06

Hi, I am simply trying out different math fonts available, and found iwona-heavy to be "strange". Look at the output of \usetypescript [iwona-heavy][ec] \setupbodyfont[iwona-heavy,ss,11pt] \starttext This is some test \startformula \Pr(A = B) = \frac 12 \stopformula \stoptext The math is much bolder than the text. Is this by design? Aditya
