| " Vim completion script
 | |
| " Language:    All languages, uses existing syntax highlighting rules
 | |
| " Maintainer:  David Fishburn <dfishburn dot vim at gmail dot com>
 | |
| " Version:     10.0
 | |
| " Last Change: 2012 Oct 20
 | |
| " Usage:       For detailed help, ":help ft-syntax-omni" 
 | |
| 
 | |
| " History
 | |
| "
 | |
| " 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.
