" REVISION DATE REMARKS
" 1.50.019 05-May-2009 Do not create mappings for select mode;
" according to|Select-mode|, printable character
" commands should delete the selection and insert
" the typed characters.
" Moved functions from plugin to separate autoload
" script.
" Split off documentation into separate help file.
" Now cleaning up Create...Mappings functions.
" 1.40.018 30-Jun-2008 Minor: Removed unnecessary <script> from
" mappings.
" 1.40.017 19-May-2008 BF: Now using :normal! to be independent from
" any user mappings. Thanks to Neil Walker for the
" patch.
" 1.40.016 28-Apr-2008 BF: Wrong forward motion stop at the second
" digit if a word starts with multiple numbers
" (e.g. 1234.56789). Thanks to Wasim Ahmed for
" reporting this.
" 1.40.015 24-Apr-2008 ENH: Added inner "word" text objects 'i,w' etc.
" that work analogous to the built-in 'iw' text
" object. Thanks to David Kotchan for this
" suggestion.
" 1.30.014 20-Apr-2008 The motions now also stop at non-keyword
" boundaries, just like the regular motions. This
" has no effect inside a CamelCaseWord or inside
" underscore_notation, but it makes the motions
" behave like the regular motions (which is
" important if you replace the default motions).
" Thanks to Mun Johl for reporting this.
" Now using non-capturing parentheses \%() in the
" patterns.
" 1.30.013 09-Apr-2008 Refactored away s:VisualCamelCaseMotion().
" Allowing users to use mappings different than
" ,w ,b ,e by defining <Plug>CamelCaseMotion_?
" target mappings. This can even be used to
" replace the default 'w', 'b' and 'e' mappings,
" as suggested by Mun Johl.
" Mappings are now created in a generic function.
" Now requires Vim 7.0 or higher.
" 1.20.012 02-Jun-2007 BF: Corrected motions through mixed
" CamelCase_and_UnderScore words by re-ordering
" and narrowing the search patterns.
" 1.20.011 02-Jun-2007 Thanks again to Joseph Barker for discussing the
" complicated visual mode mapping on the vim-dev
" mailing list and coming up with a great
" simplification:
" Removed s:CheckForChangesToTheSelectionSetting().
" Introduced s:VisualCamelCaseMotion(), which
" handles the differences depending on the
" 'selection' setting.
" Visual mode mappings now directly map to the
" s:VisualCamelCaseMotion() function; no mark is
" clobbered, the complex mapping with the inline
" expression has been retired.
" 1.20.010 29-May-2007 BF: The operator-pending and visual mode ,e
" mapping doesn't work properly when it reaches
" the end of line; the final character of the
" moved-over "word" remains. Fixed this problem
" unless the "word" is at the very end of the
" buffer.
" ENH: The visual mode motions now also (mostly)
" work with the (default) setting
" 'set selection=inclusive', instead of selecting
" one character too much.
" ENH: All mappings will check for changes to the
" 'selection' setting and remap the visual mode
" mappings via function
" s:SetupVisualModeMappings(). We cannot rely on
" the setting while sourcing camelcasemotion.vim
" because the mswin.vim script may be sourced
" afterwards, and its 'behave mswin' changes
" 'selection'.
" Refactored the arguments of function
" s:CamelCaseMotion(...).
" 1.10.009 28-May-2007 BF: Degenerate CamelCaseWords that consist of
" only a single uppercase letter (e.g. "P" in
" "MapPRoblem") are skipped by all motions. Thanks
" to Joseph Barker for reporting this.
" BF: In CamelCaseWords that consist of uppercase
" letters followed by decimals (e.g.
" "MyUPPER123Problem", the uppercase "word" is
" skipped by all motions.
" 1.10.008 28-May-2007 Incorporated major improvements and
" simplifications done by Joseph Barker:
" Operator-pending and visual mode motions now
" accept [count] of more than 9.
" Visual selections can now be extended from
" either end.
" Instead of misusing the :[range], the special
" variable v:count1 is used. Custom commands are
" not needed anymore.
" Operator-pending and visual mode mappings are
" now generic: There's only a single mapping for
" ,w that can be repeated, rather than having a
" separate mapping for 1,w 2,w 3,w ...
" 1.00.007 22-May-2007 Added documentation for publication.
" 006 20-May-2007 BF: visual mode [1,2,3],e on pure CamelCase
" mistakenly marks [2,4,6] words. If the cursor is
" on a uppercase letter, the search pattern
" '\u\l\+' doesn't match at the cursor position,
" so another match won. Changed search pattern
" from '\l\+',
" 005 16-May-2007 Added support for underscore notation.
" Added support for "forward to end of word"
" (',e') motion.
" 004 16-May-2007 Improved search pattern so that
" UppercaseWORDSInBetween and digits are handled,
" too.
" 003 15-May-2007 Changed mappings from <Leader>w to ,w;
" other \w mappings interfere here, because it's
" irritating when the cursor jump doesn't happen
" immediately, because Vim waits whether the
" mapping is complete. ,w is faster to type that
" \w (and, because of the left-right touch,
" preferred over gw).
" Added visual mode mappings.
" 0.02 15-Feb-2006 BF: missing <SID> for omaps.
" 0.01 11-Oct-2005 file creation
" Avoid installing twice or when in compatible mode

"- mappings -------------------------------------------------------------------
" The count is passed into the function through the special variable 'v:count1',
" which is easier than misusing the :[range] that :call supports.
" <C-U> is used to delete the unused range.
" Another option would be to use a custom 'command! -count=1', but that doesn't
" work with the normal mode mapping: When a count is typed before the mapping,
" the ':' will convert a count of 3 into ':.,+2MyCommand', but ':3MyCommand'
" would be required to use -count and <count>.
"
" We do not provide the fourth "backward to end" motion (,E), because it is
" seldomly used.

" To create a text motion, a mapping for operator-pending mode needs to be
" defined. This mapping should move the cursor according to the implemented
" motion, or mark the covered text via a visual selection. As inner text motions
" need to mark both to the left and right of the cursor position, the visual
" selection needs to be used.

" Vim's built-in inner text objects also work in visual mode; they have
" different behavior depending on whether visual mode has just been entered or
" whether text has already been selected.
" We deviate from that and always override the existing selection.
