fonts / lucida
by Hans Hagen 01 Dec '05

01 Dec '05

Hi, I uploaded a new cont-fnt.zip file. This ons has lucida metrics (ec and texnansi). If I did things right, one only needs to copy the lucida pfb files to the .../fonts/type1/bh/lucida path. Hans

IPA/TIPA support in Context?
by Jason Knight 01 Dec '05

01 Dec '05

What support is there for IPA/TIPA in Context at this point? I've had a look through the mailing list archive and the last comment I saw about it was from the first half of 2004. Has anyone done more hacking on this? Jason -- Jason Knight Systems-Analyst-at-large "They fix 'em, I break 'em. Thus, analysis."

bimath vs bfmath
by Hans van der Meer 01 Dec '05

01 Dec '05

Why does $\bfmath a \rightarrow b$ % b-f-math behaves different from $\bimath a \rightarrow b$ % b-i-math In the first I get a bold arrow, not in the second one. In bfmath the symbol font switches to bold, but in bimath it does not. The variables do change correctly to bolditalic in both cases.. Is the symbolfont in the mathfamilies not switched in \bimath? For the font (Lucida) I have normal and bold symbol definitions installed: sy=MathSymbol mo 1, \definefontsynonym [MathSymbol] [LucidaNewMath-Symbol] sybf=MathSymbolBold mo 1, \definefontsynonym [MathSymbolBold] [LucidaNewMath-Symbol-Demi] I did set \setupformulas[method=bold] in the preamble and verified that \boldfacemathmethod has the value 1. Inspection of font-bfm.tex did not give me the solution. I must confess being lost here. As an aside another observation with bold math. After: \setupformulas[method=bold] \startformula[method=bold]\bfm .... the call to \bfm makes \quad's in the math disappear (using lucidabright font setup) And in the default font (no fontsetting) \bfm even gives an error ! \textfont 7 is undefined (character !). \stopdisplaymath ->\stopinnermath $$ \ifgridsnapping \egroup \afterdisplayspa... yours sincerely, dr.

texteuro
by Hans van der Meer 01 Dec '05

01 Dec '05

I clearly have some misunderstanding about the typesetting of the euro sign. In an attempt to implement the MathTimes font and expert fontset, I came across a problem with typesetting the euro. I could not redefine the \texteuro. In \showcharacters it stays empty. Doing \definecharacter texteuro to_some_value in a typescript does not work (giving: Runaway argument?) The euro does appear when I define it explicitely (as coming from the marvosym font): \def\euro{\symbol[europe][EUR]} But then \texteuro is still unaffected and therefore doing "\enableregime[mac] € (euro)" does not work. Any pointer how to solve this? yours sincerely, dr. H. van der Meer

blackboard and calligraphic
by Hans van der Meer 01 Dec '05

01 Dec '05

From: hansm(a)science.uva.nl Subject: blackboard bold and calligraphic Date: November 28, 2005 17:46:07 GMT+01:00 To: ntg-context(a)ntg.nl BLACKBOARD There is a problem with the Blackboard symbols, when used in regular and bold forms both. In the Lucida fontset there is a regular series in lbma (or hlcra), and a bold series in font lbmad (or hlcda). As I understand from the current code, switching from regular to bold should be accompanied by a switch from Blackboard to something like BlackboardBold in the command \bbd (from the sources I guess \bbd in font-ini.tex is the most basic macro here). The problem is that \bbd is defined as: \def\bbd {\mathortext{\fam\purefamily {blackboard}}{\symbolicfont {Blackboard}}} Thus the font is hardcoded to regular Blackboard. I have no idea what should be the best strategy to repair this. As for now, the most general mechanism for switching to other/bold math fontfamilies I could find is using \bfmath (and friends). The font needed is in one of the math font registers, of course, so something like {\ma CNRZ} instead of {\bbd CNRZ} will do for now. But this low level code makes the TeX-source explicitely dependant on the font, because for example in the AMS-series these characters are found in msmb then needing {\mb CNRZ}. Is there some generic solution here? CALLIGRAPHIC There is a similar problem with $\cal ...$ It is defined as \def\cal {\mathortext{\fam\purefamily{calligraphic}}{\symbolicfont {Calligraphic}}} I definded a font synonym "Calligraphic" but ConTeXt does not seem to use it in math mode. The calligraphic symbols appear to be taken from the sy (symbol) math family instead of the Calligraphic font. It is a problem, because in the MathTimes fonts the calligraphic letters are in another font (mtms and its bold companion). Typesetting ${\cal XYZ}\hbox{\cal XYZ}$ gives the wrong characters (coming from the symbol font) in the first XYZ, the correct letters in the second. How can this be solved? yours sincerely, dr.

'empty string' test in MP
by Peter Rolf 30 Nov '05

30 Nov '05

Hi all, I pass a string to a MP graphic using \setMPtext{LABEL}{TEXT}. The string can also be empty, and then no action (for the text) is taken. How can I test in MP, if the given \MPstring{LABEL} is empty? I have tried everything I can imagine in the last one hour, but no success. Not my day... This is the old, not working version if not(\MPstring{LABEL}="") : % is always true. Peter
