Dear list,
I have been using the Lucida fonts for long time with LaTeX, either the Type 1 version through the `lucimatx` package or the OpenType variants with `unicode-math`. In `unicode-math` there is a straightforward way to select stylistic sets, e.g. alternative calligraphic glyphs.
By default the `lucidaot` typescript switches off the alternative math italics, but I found a way to reenable them (basically just undoing what the typescript does).
\setupbodyfont[lucidaot] % get alternative math italics \setupmathrendering[lucidaot][it=] \starttext $\mathcal{C} = f(x)$ \stoptext
I only found this by chance; \setupmathrendering is not documented. Is there a more intuitive way to select the alternative math italics? Also, is there an easy way to access all the other features defined in `lucida-opentype-math.lfg`? This is the list:
alternates = { italic = { feature = 'ss01', value = 1, comment = "Mathematical Alternative Lowercase Italic" }, arrow = { feature = 'ss02', value = 1, comment = "Mathematical Alternative Smaller Arrows" }, operator = { feature = 'ss03', value = 1, comment = "Mathematical Alternative Smaller Operators" }, calligraphic = { feature = 'ss04', value = 1, comment = "Mathematical Alternative Calligraphic Characters" }, zero = { feature = 'ss05', value = 1, comment = "Mathematical Alternative Zero" }, partial = { feature = 'ss20', value = 1, comment = "Mathematical Alternative Upright Partial Differential" }, },
I extended the mechanism a bit so in the next beta you can do combinations and a global setup: \setupbodyfont[lucidaot] \starttext $x ^{i \leftarrow 0 = ∅} _{\setmathfontalternate{arrow} \setmathfontalternate{dotless} \setmathfontalternate{zero} i \leftarrow 0 = ∅} $ $x ^{i \leftarrow 0 = ∅} _{\setmathfontalternate{arrow,dotless,zero} i \leftarrow 0 = ∅} $ \setupmathematics[stylealternative={arrow,dotless,zero}] $x ^{i \leftarrow 0 = ∅} _{i \leftarrow 0 = ∅} $ \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
