You need to delete the NOSPAM part in the address.


Oh wow, I did not notice that. Apparently Charles' spam filter also works on 
humans ;) Thanks, Christian, will re-send.


Best,

Vim Yacc syntax inconsistencies

[Matthew Fernandez]

Hello vim-dev,

I sent the email below to the yacc.vim maintainer, but it seems the listed address bounces. Does anyone on this list 
have the expertise/desire to step in to maintain this file? I'd be happy to do it myself, but the complexity of this 
file is a bit above my level of Vim expertise.


Thanks,
Matt

Hi Charles,

I've been working on a Bison-generated parser recently and have come across some unexpected behaviour in syntax 
highlighting within Vim. I've never used Yacc itself before, so my understanding of it is based off its docs [0].


The highlighting rule for "%prec" looks like the following [1]:

syn match   yaccKey "\s%\(prec\|expect\)\>" contained

This doesn't seem to actually highlight "%prec" in the context in which it is 
used, trailing the body of an expression:

expr:   expr  '+'  expr
|   expr  '-'  expr
|   expr  '*'  expr
|   expr  '/'  expr
|   '-'  expr  %prec  '*'
|   NAME
;

Is this intentional?

I've noticed that this rule also tries to match "%expect" which doesn't seem supported by Yacc. This is supported by 
Bison and it would actually be desirable for me if highlighting worked on other newer Bison features, like the prologue 
alternatives [2]. Are you happy to accept patches that add Bison support? The complexity of yacc.vim is above my level 
of Vimscript competence, but I'm sure I can learn what I need from the Vim docs.


If you're no longer the maintainer of this file, please let me know who I should contact about this issue. Thank you for 
your time.


Thanks,
Matt
