" 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.
"
" The ftdetect/perl11.vim file in this repository takes care of setting the
" right filetype for Perl 6 files. To set it explicitly you can also add this
" line near the bottom of your source file:
" # vim: filetype=perl6
" TODO:
" * Go over the list of keywords/types to see what's deprecated/missing
" * Add more support for folding (:help syn-fold)
"
" 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://github.com/parrot/parrot/tree/master/editor
"
" To highlight Perl 5 regexes (m:P5//):
" let perl6_perl5_regexes=1
"
" To enable folding:
" let perl6_fold=1
if version < 704 | throw "perl6.vim uses regex syntax which Vim <7.4 doesn't support. Try 'make fix_old_vim' in the vim-perl repository." | endif
" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
if version < 600
syntax clear
elseif exists("b:current_syntax")
finish
endif
