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

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

colored box background
by Hans van der Meer 14 Jul '06

14 Jul '06

Say I have a box, e.g. \setbox\thebox=\vbox{....} with dimensions \wd \thebox etc. What then is the most efficient and economic (in terms of complexity and speed) way to generate a colored background for it? I know I can use \framed, but this I wish to avoid because it seems overly complex for this simple task and may have side effects in terms of alignment issues. Is the best perhaps using a metapost graphic? and if so, what is best MPgraphic, useMPgraphic, reuseMPgraphic, etc.? Hans van der Meer

Version Numbers in Download File Names
by Matthias Wächter 13 Jul '06

13 Jul '06

Hi! Pardon me for requesting more support from pragma-ade prior to ever using the mailing list for general support questions. Maybe I should post this one directly to Hans but others might be interested in this issue as well. Despite my little but growing knowledge of Context I am currently evaluating its suitability for document building in our company (our workflow is currently Latex-based). A prime aspect of our company's work is to follow well-defined processes, and as part of that, we have to be able to refer to specific versions of applications that are used in the development of our projects. When used, this would apply to Context as well. Obviously, downloading from pragma-ade gives version numbers only on the entry pages like http://www.pragma-ade.nl/download-1.htm next to the links to the files, but the package files themselves like http://www.pragma-ade.nl/context/current/cont-tmf.zip don't have versioned names (not mentioning that Context and its modules actually _do_ report version numbers as dates upon use). Is there a strong motivation against having versioned package file names, possibly with some months/years of history? Has this support feature ever been considered by pragma-ade or asked for by their (non-)paying customers? Or is this archive available but I am unable to find it? ;) Just an example: Instead of http://www.pragma-ade.nl/context/current/cont-tmf.zip use a browseable directory like http://www.pragma-ade.nl/context/archive/ containint files like http://www.pragma-ade.nl/context/archive/cont-tmf-20060518.zip http://www.pragma-ade.nl/context/archive/cont-tmf-20060601.zip http://www.pragma-ade.nl/context/archive/cont-tmf-20060629.zip and possibly set /context/current/cont-tmf.zip as an internal file system link to the latest file in /context/archive/ for those interested only in the latest version. The proposed method could be applied to all other download files as well. That way and as long as the archive files are available, a precise version of Context could be fetched from pragma-ade's server without maintaining a local versioned archive of cont.tmf.zip etc. Referral to a specific version of Context would be a lot easier, and documenting the tools used for a project would be a lot simpler. A common understanding of a Context version, reflected in its package file name, would reduce the effort of those responsible for local version control and install package maintenance. Thanks, - Matthias
