Hi, In the wiki, fallback often appears in the definition of typescript. I am curious about this ``fallback", is there a place to learn the fallback in detail? I haven't found this place in our wiki. Regards, Tim

Hi Tim,

use the source, Luke:
http://repo.or.cz/w/context.git/blob/refs/heads/origin:/tex/context/base/font-col.mkvi#l94
As the manual says:
It really makes sense to take a look at the font and type
definition files (font-*.tex and type-*.tex). There are
fallbacks defined, as well as generic definitions. Studying
styles and manual source code may also teach you a few tricks.
I assure you the effort is well worth it.
Best regards
Philipp

That won’t help to understand what’s the meaning of these lines.
To demonstrate what these lines are for a wrote a small example.
\starttypescript[serif][palatino-clone]

\definefontsynonym [SerifItalic] [file:texgyrepagellaitalic] [features=default]
\stoptypescript
\starttypescript[sans][helvetica-clone]

\setupbodyfont[mainface]
\starttext
\rm\tf Regular \it Italic \sl Slanted
\ss\tf Regular \it Italic \sl Slanted
\stoptext
When you put the code in a file and process you will notice that “\sl Slanted” always uses
the upright Pagella font, this happens because no font was set for this style in the typescripts
and a default font is used.
You prevent this unwanted result by adding additional \definefontsynonym lines to the
typescript where you say context to use the italic font for the slanted style.
\starttypescript[serif][palatino-clone]
\definefontsynonym [Serif] [file:texgyrepagellaregular] [features=default]
\definefontsynonym [SerifItalic] [file:texgyrepagellaitalic] [features=default]
\definefontsynonym [SerifSlanted] [SerifItalic]
\stoptypescript
\starttypescript[sans][helvetica-clone]
\definefontsynonym [Sans] [file:texgyreherosregular] [features=default]
\definefontsynonym [SansItalic] [file:texgyreherositalic] [features=default]
\definefontsynonym [SansSlanted] [SansItalic]
\stoptypescript
Still this wouldn’t be enough when you want to use also the bold and bolditalic
styles for your font even more fallback definitions are needed. The complete
typescript for the serif font has to look now like this.
\starttypescript[serif][palatino-clone]
\definefontsynonym [Serif] [file:texgyrepagellaregular] [features=default]
\definefontsynonym [SerifItalic] [file:texgyrepagellaitalic] [features=default]
\definefontsynonym [SerifSlanted] [SerifItalic]
\definefontsynonym [SerifBold] [Serif]
\definefontsynonym [SerifBoldItalic] [SerifBold]
\definefontsynonym [SerifBoldSlanted] [SerifBoldItalic]
\definefontsynonym [SerifCaps] [Serif]
\stoptypescript
Because such fallback definitions are needed for many font (especially the slanted
to italic mappings) you can predefined lists in type-fbk.mkiv which you can load
at the begin at your typescript to save a few lines and we can abbreviate the above
typescript in this form.
\starttypescript[serif][palatino-clone]
\setups[font:fallback:serif]
\definefontsynonym [Serif] [file:texgyrepagellaregular] [features=default]
\definefontsynonym [SerifItalic] [file:texgyrepagellaitalic] [features=default]
\stoptypescript

Wolfgang, many thanks to you, for your comprehensive explaination. After reading your mail, as a ConTeXt user, I think I can apply the `fallback' to my typescript definition well. Tim
