- " Vim completion script
- " Language: All languages, uses existing syntax highlighting rules
- " Maintainer: David Fishburn <dfishburn dot vim at gmail dot com>
- " Version: 8.0
- " Last Change: 2011 Nov 02
- " Usage: For detailed help, ":help ft-syntax-omni"
-
- " History
- "
- " 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.
