124 Math display display style, like text style but somewhat more spacy text text style, normally used inline script smaller than text cq. display style scriptscript smaller than script style cramped packed more tightly positioned superscripts uncramped normal normal positioned superscripts small switch to the next smaller style but keep cramp state big switch to the next larger style but keep cramp state Future versions of MkIV will provide more features (like parameter sets driven by keywords). As you might prefer a more symbolic approach we provide: \definemathstyle[default][text,cramped] After this you can use the keyword default which has the advantage that you only need to change one definition in order to get different rendering. 7.6 Supported fonts As in ConT E Xt MKIV I wanted to go ahead with Unicode math as soon as the first version of LuaT E X showed up. Because at that time only Cambria was available I decided to provide virtual Unicode math fonts as a prelude to proper replacements for the popular Type1 math fonts. In the meantime Xits came around and in 2012 we had quite useable math companions for the public Latin Modern, Pagella and Termes fonts and the T E X user groups started shipping OpenType variants of Lucida. The virtual variants will still around so that we can compare them with the new implementations. As the official specification of OpenType math is not always clear from the beginning the OpenType fonts get improved over time. In fact, this is true not only for math fonts. Just think of this: • As Unicode gets extended, fonts might get more glyphs and possibly alternate shapes. • The more languages are supported, the more glyphs are to be available and features have to get language dependent instances. • The larger the font, the bigger the chance that mistakes get unnoticed especially when contextual subtitutions and positioning are used. • Math fonts can get more script and scriptscript alternates, more size variants, more advanced extensibles, bidirectional support, etc. So, like regular programs, LuaT E X and macro packages, we now have fonts as component that needs occasional updating. Of course resources like hyphenation patterns are also subjected to this, so it’s not a new aspect. But still, best keep en eye on font updates.
While there are lots of text fonts, there are not that many math fonts, so you can safely assume that ConT E Xt ships with the proper setup for those fonts. Of course you have to choose a specific instance when you set up your own combination of fonts, but a peek into the typescripts shows the way. In the font manual and on the wiki you can find more about typescript and what is possible, so here we just take a look at one definition: \starttypescript [serif] [dejavu] [name] \definefontsynonym [Serif] [name:dejavuserif] [features=default] \definefontsynonym [SerifBold] [name:dejavuserifbold] [features=default] \definefontsynonym [SerifItalic] [name:dejavuserifitalic] [features=default] \definefontsynonym [SerifBoldItalic] [name:dejavuserifbolditalic] [features=default] \stoptypescript \starttypescript [sans] [dejavu] [name] \definefontsynonym [Sans] [name:dejavusans] [features=default] \definefontsynonym [SansBold] [name:dejavusansbold] [features=default] \definefontsynonym [SansItalic] [name:dejavusansoblique] [features=default] \definefontsynonym [SansBoldItalic] [name:dejavusansboldoblique] [features=default] \stoptypescript \starttypescript [mono] [dejavu] [name] \definefontsynonym [Mono] [name:dejavusansmono] [features=none] \definefontsynonym [MonoBold] [name:dejavusansmonobold] [features=none] \definefontsynonym [MonoItalic] [name:dejavusansmonooblique] [features=none] \definefontsynonym [MonoBoldItalic] [name:dejavusansmonoboldoblique] [features=none] \stoptypescript \starttypescript[dejavu] \definetypeface [dejavu] [rm] [serif] [dejavu] [default] \definetypeface [dejavu] [ss] [sans] [dejavu] [default] \definetypeface [dejavu] [tt] [mono] [dejavu] [default] \definetypeface [dejavu] [mm] [math] [xits] [default] [scale=1.2] \stoptypescript So, in many cases you can just copy this blob and replace the font names by your own. Loading a font, and Dejavu is a predefined one, is done as follows: \setupbodyfont[dejavu] In a similar fashion you can enable cambria, pagella, termes, lucidaot, etc. and if you don’t use this command at all, you get Latin Modern. These fonts are part of T E X distributions, including ConT E Xt stand--alone that can be downloaded from ConT E Xt garden. If you want to use Lucida, all you have to do when you have bought the fonts, is to put the OpenType files in a place where they can be found, for instance: 125 Math
