\startchapter[title={Setups}]
Setups are a powerful way to organize styles. They are basically macros but live
in their own namespace. One advantage is that spaces in a setup are ignored so
you can code without bothering about spurious spaces. Here is a trick that you
can use when one style contains directives for multiple products:
\startbuffer
\startsetups tex:whatever
\fastsetup{tex:whatever:\documentvariable{stylevariant}}
\stopsetups
\startsetups tex:whatever:foo
FOO
\stopsetups
\startsetups tex:whatever:bar
BAR
\stopsetups
\stopbuffer
\typebuffer \getbuffer
Here we define a main setup \type {tex:whatever} that gets expanded in one of two
variants, controlled by a document variable.
\startbuffer
\setups{tex:whatever}
\setupdocument
[stylevariant=foo]
\setups{tex:whatever}
\setupdocument
[stylevariant=bar]
\setups{tex:whatever}
\stopbuffer
\typebuffer
These lines result in:
\getbuffer
In a similar fashion you can define \XML\ setups that are used to render
elements:
\starttyping
\startxmlsetups xml:whatever
\xmlsetup{#1}{xml:whatever:\documentvariable{stylevariant}}
\stopxmlsetups
\startxmlsetups xml:whatever:foo
FOO: \xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:whatever:bar
BAR: \xmlflush{#1}
\stopxmlsetups
\stoptyping
\stopchapter
