" Vim completion script
" Language: All languages, uses existing syntax highlighting rules
" Maintainer: David Fishburn <dfishburn dot vim at gmail dot com>
" Version: 13.0
" Last Change: 2013 May 14
" Usage: For detailed help, ":help ft-syntax-omni"
" History
"
" Version 13.0
" - Extended the option omni_syntax_group_include_{filetype}
" to accept a comma separated list of regex's rather than
" string. For example, for the javascript filetype you could
" use:
" let g:omni_syntax_group_include_javascript = 'javascript\w\+,jquery\w\+'
" - Some syntax files (perl.vim) use the match // syntax as a mechanism
" to identify keywords. This update attempts to parse the
" match syntax and pull out syntax items which are at least
" 3 words or more.
"
" Version 12.0
" - It is possible to have '-' as part of iskeyword, when
" checking for character ranges, tighten up the regex.
" E688: More targets than List items.
"
" Version 11.0
" - Corrected which characters required escaping during
" substitution calls.
"
" Version 10.0
" - Cycle through all the character ranges specified in the
" iskeyword option and build a list of valid word separators.
" Prior to this change, only actual characters were used,
" where for example ASCII "45" == "-". If "45" were used
" in iskeyword the hyphen would not be picked up.
" This introduces a new option, since the character ranges
" specified could be multibyte:
" let g:omni_syntax_use_single_byte = 1
" - This by default will only allow single byte ASCII
" characters to be added and an additional check to ensure
" the charater is printable (see documentation for isprint).
"
" Version 9.0
" - Add the check for cpo.
"
" Version 8.0
" - Updated SyntaxCSyntaxGroupItems()
" - Some additional syntax items were also allowed
" on nextgroup= lines which were ignored by default.
" Now these lines are processed independently.
"
" Version 7.0
" - Updated syntaxcomplete#OmniSyntaxList()
" - Looking up the syntax groups defined from a syntax file
" looked for only 1 format of {filetype}GroupName, but some
" syntax writers use this format as well:
" {b:current_syntax}GroupName
" - OmniSyntaxList() will now check for both if the first
" method does not find a match.
"
" Version 6.0
" - Added syntaxcomplete#OmniSyntaxList()
" - Allows other plugins to use this for their own
" purposes.
" - It will return a List of all syntax items for the
" syntax group name passed in.
" - XPTemplate for SQL will use this function via the
" sqlcomplete plugin to populate a Choose box.
"
" Version 5.0
" - Updated SyntaxCSyntaxGroupItems()
" - When processing a list of syntax groups, the final group
" was missed in function SyntaxCSyntaxGroupItems.
"
" Set completion with CTRL-X CTRL-O to autoloaded function.
" This check is in place in case this script is
" sourced directly instead of using the autoload feature.

" Do not set the option if already set since this
