Hiding subanswer blocks
by David Arnold 15 Jul '06

15 Jul '06

All, Below I have our environment for our question and answer blocks. We are attempting to have questions that have parts, as in: 1. Yada, Yada, Yada, Yada, Yada, Yada, Yada, Yada, Yada. 1a) Yada, Yada, Yada, Yada, Yada, Yada, Yada, Yada, Yada. 1b) Yada, Yada, Yada, Yada, Yada, Yada, Yada, Yada, Yada. 1c) Yada, Yada, Yada, Yada, Yada, Yada, Yada, Yada, Yada, 2, 2a) 2b) Etc. However, we want to "hide" some of the shortsubanswers. We try with: \beginshortanswer \startanswer \startsubanswer[-] \stopsubanswer \startsubanswer[-] \stopsubanswer \startsubanswer[-] \stopsubanswer \startsubanswer \startbuffer ... When typeset, the first three subanswers here are hidden, but the first subanswer that is not hidden, which should be the answer to "part d," it winds up be labeled "part a" in the pdf output. Can anyone help? \def\genericqacommands#1{\unnumberedsubsection{#1}\vskip 1em} \def\startgenericqadouble#1{\genericqacommands{#1}\startcolumns[n=2]} \def\stopgenericqadouble{\stopcolumns} \def\startgenericqasingle#1{\genericqacommands{#1}} \def\stopgenericqasingle{} \def\preqacontainment{\vskip 0.5ex plus 1ex} \def\postqacontainment{\vskip 0.5ex plus 1ex} \def\startquestions{\startgenericqadouble{Exercises}} \def\stopquestions{\stopgenericqadouble} \def\startlonganswers{\startgenericqasingle{Answers}} \def\stoplonganswers{\stopgenericqasingle} \def\startshortanswers{\startgenericqadouble{Answers}} \def\stopshortanswers{\stopgenericqadouble} \def\questionbreak{\vskip 2em plus 1ex minus 1 ex} \def\placeanswers{% \doifmodeelse{short} { \startshortanswers \selectblocks[shortanswer,shortsubanswer][criterium=section] \stopshortanswers } { \startlonganswers \selectblocks[longanswer,longsubanswer][criterium=section] \stoplonganswers } } \defineenumeration [question] [text=, headcolor=heavygreen] \setupenumerations [question] [location=left, width=fit, distance=1em, hang=1, margin=0pt, headcolor=heavygreen, right=., way=bysection, sectionnumber=no, before=\preqacontainment, after=\postqacontainment] \defineenumeration [subquestion] [location=hanging, text=, headcolor=heavygreen, conversion=characters] \setupenumerations [subquestion] [right=)] \defineenumeration [answer] [text=, headcolor=heavygreen] \setupenumerations [answer] [location=left, width=fit, distance=1em, hang=1, margin=0pt, headcolor=heavygreen, right=., way=bysection, sectionnumber=no, before=\preqacontainment, after=\postqacontainment] \defineenumeration [subanswer] [location=hanging, text=, headcolor=heavygreen, conversion=characters] \setupenumerations [subanswer] [right=)] \defineblock [question,shortanswer,longanswer,subquestion,shortsubanswer,longsubanswe r] \hideblocks[shortanswer,longanswer,shortsubanswer,longsubanswer]

regenerating formats
by Alan Bowen 15 Jul '06

15 Jul '06

I downloaded the latest ConTeXt and tried regenerating the hyphenation patterns and formats (to get hyphenation with Thomas’ Greek module). The first step texmfstart ctxtools --pat was successful. But sudo texmfstart texexec --make --all (which worked with the last ConTeXt installation) and sudo -H texmfstart texexec --make --all failed with the error message sudo: texmfstart: command not found. Fortunately, sudo texexec --make --all still works, so life goes on. Still, why is this happening? Does it matter that I have the line alias texmfstart='ruby /usr/local/teTeX/share/texmf.local/scripts/ context/ruby/texmfstart.rb' in my .profile rather than an executable version of the texmfstart script in my $PATH? If it does, is there a way to set things so that texmfstart is automatically available to the administrator and user whenever a Terminal session is begun? Alan

frames in natural tables
by wwl＠musensturm.de 14 Jul '06

14 Jul '06

Hallo! In the following example with two nearly identical tables: ---------------------------------------------------------- \starttext \setupTABLE[r][each][frame=off] \setupTABLE[r][first][bottomframe=on,rulethickness=.05em] \bTABLE \bTR \bTD Nr.\ \eTD \bTD Eintrag \eTD \eTR \bTR \bTD 1 \eTD \bTD Bla \eTD \eTR \bTR \bTD 2 \eTD \bTD Blub \eTD \eTR \bTR \bTD 3 \eTD \bTD Boing \eTD \eTR \bTR \bTD 4 \eTD \bTD Blubber \eTD \eTR \eTABLE \blank %\setupTABLE[frame=off] \setupTABLE[r][first][bottomframe=off] \bTABLE[frame=off] \bTR \bTD Nr.\ \eTD \bTD Eintrag \eTD \eTR \bTR \bTD 1 \eTD \bTD Bla \eTD \eTR \bTR \bTD 2 \eTD \bTD Blub \eTD \eTR \bTR \bTD 3 \eTD \bTD Boing \eTD \eTR \bTR \bTD 4 \eTD \bTD Blubber \eTD \eTR \eTABLE \stoptext ---------------------------------------------------------- the first \setupTABLE[r][each][frame=off] switched frames off and the second \setupTABLE[r][first][bottomframe=on,rulethickness=.05em] switched the bottomframe on in the first row. but in the second table neighter \setupTABLE[frame=off] nor \setupTABLE[r][each][frame=off] switched frames off the bottomframe in row 1 survives from the first table! One has explicitly use \setupTABLE[r][first][bottomframe=off] to switch this frameline off too. So, 1. Is there no general 'frame=off'? 2. Is the first \setupTABLE not really working? It should, because the defaults are 'frame=on', aren't they? Wolfgang

eating up &
by Hans van der Meer 14 Jul '06

14 Jul '06

I want to do something with & in tables (making it an active column separator). Now I have a macro with two arguments for parameters in Context style: \def\starttablex{\dodoubleargument\dostarttablex} \def\dostarttablex[#1][#2]{% Now for input: \starttable[][] & ... all is well, but for input: \starttable[] & ... the ampersand appears to be eaten up by the double argument expansion. How can I prevent that, letting & end the parameter scanning and using it as the first input? Hans van der Meer

positionoverlays problem
by Hans van der Meer 14 Jul '06

14 Jul '06

I want to use the positionoverlay mechanism in several different figures (according to the metafun manual "Anchors and layers"). The problem is that the overlays show up in the last figure only, not in the first. If I do not typeset the second overlayseries, the first does appear. It looks like only the last overlayseries is kept. Why is this and how to remedy this? Like this with several names overlay names: \def\startoverlaygraphics#1{% \startpositionoverlay{#1}% } \def\stopoverlaygraphics#1{% \stoppositionoverlay \defineoverlay[#1][\positionoverlay{#1}] \setupbackgrounds[page][background={foreground,#1}] } Using it in: \startoverlaygraphics{graphics-1} \setMPpositiongraphic{A1}{syllabus:arrow}{to=B1} etc. \stopoverlaygraphics{graphics-1} ...\hpos{A1}{}...\hpos{B1}{}... \startoverlaygraphics{graphics-2} \setMPpositiongraphic{E1}{syllabus:arrow}{to=F1} etc. \stopoverlaygraphics{graphics-2} ...\hpos{E1}{}...\hpos{F1}{}... Arrows drawn with: \setupMPvariables[syllabus:arrow]% [linestyle={dashed evenly},% linesize=\tableframethickness, coloring=FrameColor,% axoff=0pt, ayoff=0pt, bxoff=0pt, byoff=0pt] \startMPpositiongraphic{syllabus:arrow}{coloring} pair a, b; initialize_box(\MPpos{\MPvar{from}}); a := cxy; initialize_box(\MPpos{\MPvar{to}}); b:= cxy; pickup pencircle scaled \MPvar{linesize}; drawarrow (a + (\MPvar{axoff},\MPvar{ayoff})) -- (b + (\MPvar{bxoff},\MPvar{byoff})) \MPvar{linestyle} withcolor \MPvar{coloring}; anchor_box(\MPanchor{\MPvar{from}}); \stopMPpositiongraphic \endinput Hans van der Meer

Hi, Anyone on this list use BBEdit for the Context editing? If so, do you know how to get the spell checked in BBEdit to ignore Context keywords?

Question and Answer Blocks -- Feed back in one or two column mode.
by David Arnold 14 Jul '06

14 Jul '06

All, If we have about 45 question blocks and accompanying answer blocks, how can we typset some of the answer blocks in two column mode, other of the answer blocks in one column mode, and the rest back in two column mode. We don't mind manually editing a file to accomplish this.

tracingmacros
by Hans van der Meer 14 Jul '06

14 Jul '06

Usually I employ \tracingmacros=1 in order to find nasty problems in my macros. Font operations then produce a lot of noise in the log. Is it possible to shutdown these selectively? Hans van der Meer
