Re: [NTG-context] metafun color broken?

After posting this problem I did probe a lot further in this and a similar problem. As I reported shortly, the problem goes away when solely replacing in supp-mps.tex the line \ifx\TEXEXECcommand \undefined \def\TEXEXECcommand{texmfstart texexec} \fi by \ifx\TEXEXECcommand \undefined \def\TEXEXECcommand{texexec} \fi This gives me the impression it might not be in context itself, especially since to my (inexperienced) eye there are no or few changes between the working and nonworking versions that might explain the problem. It might be the change from the perl to the ruby scripts with a problem in one of the latter. I expect Hans or Taco to react soon with there usual speed and will await for their comments first.

But in this case formerly perfectly working code is suddenly broken.

mathsize
by Hans van der Meer 15 Jun '06

15 Jun '06

When doing inline math I see that the mathsize does adapt when \tfa, \tfb, etc are used, but not for \tfx and \tfxx. That seems strange to me, because in the manual in the font table \tfx \tfxx \tfa etc. are advertised as equivalent operations. It also accounts for a lot more typing (and mistakes). Why is the behaviour different? And if it is not on purpose, can it be remedied then? A minimal example: \starttext {\tfc tfc 123 and \$ tfc: $123$ \$}\crlf {\tfb tfb 123 and \$ tfb: $123$ \$}\crlf {\tfa tfa 123 and \$ tfa: $123$ \$}\crlf {normal 123 en \$ normal: $123$ \$}\crlf {\tfx tfx 123 and \$ not tfx: $123$ \$}\crlf % math does not adapt size {\tfx tfx 123 and \$ again tfx: $\tfx 123$ \$}\crlf {\tfxx tfxx 123 and \$ not tfxx: $123$ \$}\crlf % math does not adapt size {\tfxx tfxx 123 and \$ again tfxx: $123$ \$}\crlf % the next does work as expected: \def\smallsize{\switchtobodyfont[9pt]} {\smallsize smallsize 123 and \$ smallsize: $123$ \$}\crlf Hans van der Meer

Math: Matrix question
by Tobias Burnus 15 Jun '06

15 Jun '06

Hello, maybe someone has an idea how to typeset the following c d a [E F] b [G H] Where EFGH is a matrix surrounded by "( )" and with "a b c d" I want to label the columns and rows. I especially struggle with aligning c and d and having the parenteses. Any ideas are highly welcome. Tobias

Specifying maximum width of a frame
by Aditya Mahajan 15 Jun '06

15 Jun '06

Hi, I want to specify the maximum width of a frame. If the size of the box is smaller than the maximum width, I want a tight box. Something like \frame[maxwidth=5cm,align=middle]{Small} should give +-----+ |small| +-----+ while \frame[maxwidth=5cm,align=middle]{A very very long line that is split at 5cm} should give +----------------------+ | A very very long | | line that is split | | at 5cm | +----------------------+ Is there something builtin that does this, or do I need to play with scratchbox cum suis.

Another 2 index bugs
by Richard Gabriel 15 Jun '06

15 Jun '06

Hello Hans, I've just noticed another two bugs in index sorting. 1. Numbers are sorted under A 2. Symbols are sorted under the first letter which follows. See the attached test file. Both these issues are independent on language and on the expansion type. Proposed solution: 1. Sort numbers into separate divisions 2. Sort symbols to a special division called "Symbols" Thanks, Richard

keeping output
by Hans van der Meer 15 Jun '06

15 Jun '06

This question must have been asked before, but I cannot find it. Running texexec a number of messages flash by: error in metapost run : syllabus-s-mpgraph.mp:397 Alas, al the intermediate results disappear, especially the mpgraph files. And of the metapost logs also one only survives. How does one preserve all these for debugging purposes? Hans van der Meer

textext error
by Hans van der Meer 15 Jun '06

15 Jun '06

I am afraid a serious error has been introduced into textext in the last update(s). This used to work in metapost for typesetting text with a %-sign: label(textext("66\%"), origin); Now the % somewhere ends a line prematurely because the job aborts with: ! mpx file ended unexpectedly. Can Hans please repair this, suddenly a lot of my typesetting is broken. Hans van der Meer

Using metapost figures in context
by Aditya Mahajan 14 Jun '06

14 Jun '06

Hi, Does there exist a startstop command (say startMPfigure) for managing figures drawn using MP such that 1. I can use \startMPfigure{label} ...... \stopMPfigure and then use \useexternalMPfigure{label} to include the figure. 2. The figures are converted into pdf once. If the code inside \startstop MPfigures changes, the pdf for each figure is recreated. Basically, I want MPfigures to be converted into pdf for faster inclusion in the main document, the figure should be recompiled if necessary and I should be able to include the figure using a label (so that I can separate the figures from the main document). uniqueMPgraphic provides the first functionality, but the figure is converted into pdf on runtime (thereby increasing the processing time of the document). I can use a separate document with each figure inside a \startMPpage ... \stopMPpage, but (i) I need to remember figure numbers manually, (ii) after making change in one figure, the whole file needs to be recompiled. Another possibility is to use one tex file for each figure, compile them separately and then then use figure library to get a "label" for each figure. But this becomes difficult to manage, as soon as I get large number of files. Is their something basic that I am missing here? How do others manage mpfigures? To Hans: is it possible to have a \startMPfigure command such that 1. \startMPfigure[label] figure code \stopMPfigure creates a \jobname-figure-\nofMPfigurefile file with current MP environment current MP inclusion figure code (from inside \startstop MPfigure) Convert this into \jobname-figure-\nofMPfigurefile.pdf only if something changes (similar to what is done in m-r module). 2. The resultant pdf can be included using \useMPfigure{label}. Would such a feature make sense? Aditya
