I am interested in Unicode-capable TeX engines, and as such felt
that after fontspec and unicode-math, polyglossia would deserve
a rewrite for expl3. polyglossia currently uses etoolbox to
provide features much similar to what is offered by the LaTeX3
packages, notably a lot of keyval-like features. I found benefits
in the nice syntax offered by l3keys, and the \prg_case_str
function for example.
You may find a Git repository at
I am looking for help in testing this, hoping that you will like it,
and I have also a question: for some reason, in polyglossia
we need to (un)capitalize words for use in csnames.
I think I can produce somthing like this in LaTeX 3:
produces Abc as expected.
The TeX code is polyglossia is like this:
I have been trying to replace it by something like
or some combination using \exp_args but the result was never
equivalent, since in polyglossia the input may be a complicated
macro and the output will be surrounded by \csname..\endcsname
How should I do that ?
