Hi.
The command \iint is defined in context (mkiv) but it doesn't produce
the desired sign. What I should do to make it appear? (in log file I see
that LMMath font desn't contain such symbol but I don't know much about
font mechanism of context, btw in latex I could easily get that symbol
so I think it should be in 'standard' math font).
Minimal example:
<example file="ex1.tex">
%%% By default context minimal doesn't give easy access to \iint — double integral sign
\starttext
This is ordinary integral (sign):
\startformula
\int_{a}^{b}f(x) \text{d}x = F(x)+C
\stopformula
Though the command \type{\iint} is defined it doesn't give proper sign (in MkIV). Example:
\startformula
\iint_{D}f(x,y)\text{d}x\text{d}y
\stopformula
\stoptext
</example>

No, the symbol is not in the 'standard' math fonts, and this is trouble. Like LaTeX, we also fake the glyph in MkII. In MkIV, we check if the font contains that glyph; if not we fake it. Currently, that test is failing. A temporary workaround (for LM) is to redefine: \def\repeatintegral#1#2#3% {\let\dointlimits\donothing \let\dodointlimits\intlimits %\iffontchar\textfont\zerocount#1\relax % %\edef\dodorepeatintegral{\utfchar{#1}}% % \let\dodorepeatintegral#2% %\else \fakerepeatintegral{#3}% %\fi \futurelet\next\dorepeatintegral} and then \iint \iiint etc will work. Hans, do you know what the \textfont check is not working for LM? The ideal solution is to add esint glyphs to the LM math virtual font. I did not work on this because I was assuming that opentype LM math will be out soon. But it seems that right now, the only decent opentype math font is Cambria. Both Stix and Asansa give really horrible spacing at times.

Though I had a policy to not change XITS spacing from what STIX have unless absolutely necessary, I've recently (silently) dropped that policy, so if you can point to specific improvements, I can try to do it.

Thank you for advice (I had to regenerate format to see the result, because I changed the definition in 'math-int.mkiv') but the result is terrible for inline math and normal for displaystyle. Moreover I found that this solution would give unexpected result if one use \setupmathematics[integral=displaylimits], consider the following example: <example name="ex7_1.tex"> \setupmathematics[integral=displaylimits] \starttext Ordinary integral: $\int_{a}^{b}f(x)\text{d}x=F(b)-F(a)$. Ordinary integral: $\int\limits_{a}^{b}f(x)\text{d}x=F(b)-F(a)$. \startformula \int_{a}^{b}f(x)\text{d}x=F(b)-F(a). \stopformula Double integral: $\iint_{D} f(x,y) dx dy$ Double integral sign (faked symbol) could cause incorrect result: \startformula \iint_{D} f(x,y) \text{d}x \text{d} y \stopformula \stoptext </example> (I didn't remember where exactly I found command \setupmathematics.) > Hans, do you know what the \textfont check is not working for LM? > The ideal solution is to add esint glyphs to the LM math virtual font.

Both Stix and Asansa give really horrible spacing at times. IMHO, Cambria looks very odd. I prefer to use CM fonts, the design for different font families (serif, sans, monospace) is more balanced than any other font families have. --- WBR, Vladimir Lomov ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 4+ messages in thread
