Too many places for `\e`
We should revise the way the pretty-printing is done. Currently, we have vcsn::format
that codes the type of output we want: latex
, utf8
, text
, etc. And then each value set decodes it.
As a result, there are many places where we define the empty-word as \varepsilon
, or ε
, or \e
, etc. Maybe we should rather define in vcsn::format
all these symbols, just like vcsn::rat::printer
already does, and use it everywhere.
Then we could even offer a means to tune these symbols: they could come from configuration files instead of being hard-coded.
