" Vim syntax file " Language: Perl 6 " Maintainer: vim-perl <vim-perl@googlegroups.com> " Homepage: http://github.com/vim-perl/vim-perl/tree/master " Bugs/requests: http://github.com/vim-perl/vim-perl/issues " Last Change: 2013-07-21 " Contributors: Luke Palmer <fibonaci@babylonia.flatirons.org> " Moritz Lenz <moritz@faui2k3.org> " Hinrik Örn Sigurðsson <hinrik.sig@gmail.com> " " 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") finish endif let s:keepcpo= &cpo set cpo&vim " identifiers syn match p6Normal display "\K\%(\k\|[-']\K\@=\)*" " This is used in the for loops below " Don't use the "syn keyword" construct because that always has higher " priority than matches/regions, so the words can't be autoquoted with " the "=>" and "p5=>" operators.
