Dear all,
I'm currently struggling to get polyglossia working with french
punctuation[1]. As it is implemented with interchartokens in XeTeX, I
thought I could achieve something similar with the implementation taken
here: http://wiki.luatex.org/index.php?title=Token_filter. It works
quite well for very simple things, but I really cannot understand a few
things:
- where is the ouptut of token.command_name documented?
- how can I know if the token I get is inside a csname? (ex: in a file
I have \foobar. When, in the token_filter, I get the token b, how can I
know it's part of a csname name ?)
- same question for other characters, for example '<' in \ifnum\foo<0
It seems XeTeX handles it well, but it is possible to get this
fine-grained filtering in the token_filter, without having to expand and
inspect all tokens "by hand"?
If there is no simple solution, I'll try something with the nodes, I
think it will be more appropriate...
What do you think?
Thank you,
