[erlang-questions] A proposal for Unicode variable and atom names in Erlang.
Mon Oct 22 14:20:09 CEST 2012
Just an idea: If you want to have Unicode in your code. There is always
working solution that doesn't require to touch Erlang anyhow. You need to
setup a pre-compile hook that will run kind off parse-transform tool (PTT)
that will pre-process code and replace Unicode parts of ut to currently
allowed set of chars. Of course in CRASH DUMPS you will see replaced atoms,
but PTT can generate replacement table so, you can refer to the original
Yes, it is not very nice build-in Unicode support, but you can implement it
right now! :-)
My 1 cent.
