" This is a big undertaking. Perl 6 is the sort of language that only Perl
" can parse. But I'll do my best to get vim to.
"
" You can associate the extension ".pl" with the filetype "perl6" by setting
" autocmd BufNewFile,BufRead *.pl setf perl6
" in your ~/.vimrc. But that will infringe on Perl 5, so you might want to
" put a modeline near the beginning or end of your Perl 6 files instead:
" # vim: filetype=perl6
" TODO:
" * Deal with s:Perl5//
" * m:s// is a match, not a substitution
" * Make these highlight as strings, not operators:
" <==> <=:=> <===> <=~> <« »> «>» «<»
" * Allow more keywords to match as function calls(leave() is export(), etc)
" * Optimization: use nextgroup instead of lookaround (:help syn-nextgroup)
" * Fix s''' substitutions being matched as package names
" * Match s/// and m/// better, so things like "$s/" won't match
" * Add more support for folding (:help syn-fold)
" * Add more syntax syncing hooks (:help syn-sync)
" * Q//:
" :to, :heredoc
" interpolate \q:s{$scalar} (though the spec isn't very clear on it)
"
" Impossible TODO?:
" * Unspace
" * Unicode bracketing characters for quoting (there are so many)
" * Various tricks depending on context. I.e. we can't know when Perl
" expects «*» to be a string or a hyperoperator. The latter is presumably
" more common, so that's what we assume.
" * Selective highlighting of Pod formatting codes with the :allow option
" * Arbitrary number, order, and negation of adverbs to Q//, q//, qq//.
" Currently only the first adverb is considered significant. Anything
" more would require an exponential amount of regexes, making this
" already slow syntax file even slower.
"
" If you want to have Pir code inside Q:PIR// strings highlighted, do:
" let perl6_embedded_pir=1
"
" The above requires pir.vim, which you can find in Parrot's repository:
" https://svn.parrot.org/parrot/trunk/editor/
"
" Some less than crucial things have been made optional to speed things up.
" Look at the comments near the if/else branches in this file to see exactly
" which features are affected. "perl6_extended_all" enables everything.
"
" The defaults are:
"
" unlet perl6_extended_comments
" unlet perl6_extended_q
" unlet perl6_extended_all
" quit when a syntax file was already loaded
if exists("b:current_syntax")
