Needless to say I feel very proud now :-) For all those who are shy like me (!) and don't dare ask too trivial questions, here is what one can do on Mac OS X (and, mutatis mutandis, probably on any Unix like system): 0) I have teTeX and ConTeXt installed (and updated quite often...) with Gerben Wierda's i-Installer. In principle there is a directory (folder...) named /usr/local/teTeX/bin/ if you have installed TeX in /usr/local. Otherwise with the command locate in a Terminal window find the directory teTeX/bin/. Here there should be a subdirectory named powerpc-apple-darwin7.9.0 or something like that (depending on the type of the processor you have?). Go there, for instance in my case: cd powerpc-apple-darwin7.9.0 2) Find the path to "texmfstart.rb": in the Terminal window type locate texmfstart.rb for instance on my system I have two "texmfstart.rb", /usr/local/teTeX/share/texmf.local/scripts/context/ruby/texmfstart.rb /usr/local/teTeX/share/texmf.tetex/scripts/context/ruby/texmfstart.rb the second one is old, while the first one is recent and installed with Gerben's i-Installer. I assumed (remember we are willing to use ConTeXt...) that the newer one is the right one... 3) In the Terminal window (while you are in the directory powerpc-apple-darwin7.9.0) type: sudo emacs texmfstart and after giving an su password, in the editor's window type the code given by Taco, that is the two following lines: #!/bin/sh ruby /usr/local/teTeX/share/texmf.local/scripts/context/ruby/texmfstart.rb $@ 4) Save and exit emacs by typing [CTRL]-X [CTRL]-S and then [CTRL]-X [CTRL]-C 5) You have created a script named texmfstart... Now you have to make it executable, so in the Terminal window (while you are in the directory powerpc-apple-darwin7.9.0) type sudo chmod +x texmfstart 6) Now if in any other Terminal window you type, for instance texmfstart or texmfstart --version you should get the version of texmfstart and a series of example usage. 7) If you go to a directory where you have a file named example.tex, then you can typeset it with ConTeXt by saying: texmfstart texexec example.tex and now you shouldn't have the "warning: use 'texmfstart texexe' instead". And you are done! Cheers: OK

emp.sty and metapost
by David Arnold 28 Jun '06

28 Jun '06

All, Not strictly a context question, but it has to do with Metapost, so maybe someone can help. I have a file of macros called qdftools.mp: numeric s; s=0.2; color gridlines; gridlines:=(s,s,s); def openbluedot(expr pos)= fill fullcircle scaled 4pt withcolor white; draw fullcircle scaed 4pt withcolor blue; enddef; def openreddot(expr pos)= fill fullcircle scaled 4pt withcolor white; draw fullcircle scaed 4pt withcolor red; enddef; def filledreddot(expr pos)= fill fullcircle scaled 4pt withcolor red; draw fullcircle scaed 4pt withcolor red; enddef; def filledbluedot(expr pos)= fill fullcircle scaled 4pt withcolor blue; draw fullcircle scaed 4pt withcolor blue; enddef; def vtick(expr pos)= draw ((0,-3)--(0,3)) shifted pos; enddef; def htick(expr pos)= draw ((-3,0)--(3,0)) shifted pos; enddef; def gridfivefive = for k=-5u step 1u until 5u: draw (-5u,k)--(5u,k) withcolor gridlines; draw (k,-5u)--(k,5u) withcolor gridlines; endfor; enddef; def xyaxesfivefive= drawdblarrow (-5u,0)--(5u,0); label.rt(btex $x$ etex, (5u,0)); label.bot(btex $5$ etex, (5u,0)); drawdblarrow (0,-5u)--(0,5u); label.top(btex $y$ etex, (0,5u)); label.lft(btex $5$ etex, (0,5u)); enddef; endinput; In the same directory as qdftools.mp, I have a file useemp.tex. Note that I am using the emp package. \documentclass{article} \usepackage{amsmath} \usepackage{emp,ifpdf} \ifpdf \DeclareGraphicsRule{*}{mps}{*}{} \fi \setlength{\unitlength}{1cm} \begin{document} Now is the time for all good men to come to the aid of their country. \empprelude{input qdftools} \begin{empfile} \begin{empdef}[david](4,4) numeric u; 10u=3in; gridfivefive; xyaxesfivefive; \end{empdef} \end{empfile} \immediate\write18{mpost \jobname} \empuse{david} Now is the time for all good men to come to the aid of their country. \end{document} Now, here is what I fail to understand. If I compile useemp.tex with: pdflatex --shell-escape useemp Then all is well. I get a nice pdf file. However, if I change one line in the file useemp.tex, namely \immediate\write18{mpost \jobname} to: \immediate\write18{mpost -tex=latex \jobname} Then if I remove the file qdftools.mpx and compile useemp.tex with: pdflatex --shell-escape useemp Then I get: loading : Context Support Macros / PDF (2004.03.26) )This is MetaPost, Version 0.901 (Web2C 7.5.5) (useemp.mp (qdftools.mpnewer: target file `qdftools.mpx' doesn't exist. /usr/local/teTeX/bin/powerpc-apple-darwin-current/makempx: Command failed: latex mpxerr.tex; see mpxerr.log >> qdftools.mp >> qdftools.mpx ! Unable to make mpx file. l.41 label.rt(btex $x$ etex, (5u,0)); Transcript written on useemp.log. Can anyone tell how to work around this problem? I know Context has much better support for labels, but I need to write this in Latex for our online testing system. http://scinux.redwoods.edu/cgi-bin/ online_s06/testing.cgi/

Difficulties using the r module
by Matthew Routley 28 Jun '06

28 Jun '06

I spotted the announcement of the use of R in ConTeXt and was quite interested in trying it out. However, so far I haven't been able to get it to work. It appears that R is not being called by texexec and the .tmp.out are not being found, despite the fact that they are being produced. Are there more details on installing and using this module? I think it would be quite useful. Thanks for any advice, Matt Some details are that I am using Mac OS X 10.4.7, R-2.3.1, and ConTeXt ver: 2006.06.28 from gwTeX and running the sample file contained in m-r.tex. I have also tried using context live @ contextgarden.net with the same results as on my personal machine. Here is some output from the log file: system : module r loaded (/usr/local/teTeX/share/texmf.local/tex/context/base/m-r.tex) ... systems : begin file r at line 11 <r-r-1.tmp> (/usr/local/teTeX/share/texmf.local/tex/context/base/pdfr-ec.tex) verbatim : file r-r-1.tmp.out does not exist <r-r-2.tmp> verbatim : file r-r-2.tmp.out does not exist <r-r-3.tmp> <r-r-4.tmp> verbatim : file r-r-4.tmp.out does not exist <r-r-5.tmp> verbatim : file r-r-5.tmp.out does not exist <r-r.tmp> (./r-r.tmp figures : figure ushape can not be found floatblocks : 1 placed ) <r-r-6.tmp> verbatim : file r-r-6.tmp.out does not exist <r-r.tmp> (./r-r.tmp figures : figure lattice can not be found floatblocks : 2 placed ) <r-r-7.tmp> verbatim : file r-r-7.tmp.out does not exist ...

27 Jun '06

Hi Gerben, When trying to update ConTeXt with i-Installer, I see this: "Remote Package: Remote is being updated since 2006/06/23 04:02:30" Is it a normal situation? Thanks in advance: OK

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

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
