description
This is a script emulates Emacs Narrowing feature, by opening a selected range in a new scratch buffer.

Similar scripts:
narrow_region: http://www.vim.org/scripts/script.php?script_id=2038
narrow: http://www.vim.org/scripts/script.php?script_id=2097
narrow: http://www.vim.org/scripts/script.php?script_id=2446

Use :NarrowRegion to narrow a line based selection or alternatively visually select a range and press <Leader>nr

In the scratch buffer simply save it and the changes will be copied into the original file.
This is only a very simple help. You should probably read the help, that is provided with the plugin. See :h NarrowRegion

NrrwRgn-0.32.vmb 32 2014-03-27 7.4 Christian Brabandt - hooks could corrupt the narrowed buffer, if it wasn't closed (reported by
  jszakemeister https://github.com/chrisbra/NrrwRgn/issues/19, thanks!)
- Don't parse /doc/options.txt for finding out buffer-local options
  (reported by AguirreIF https://github.com/chrisbra/NrrwRgn/issues/21,
  thanks!), instead include a fix set of option names to set when opening the
  narrowed buffer.
- Switching buffers in the original narrowed buffer, may confuse NrrwRgn.
- Code cleanup (no more separate functions for visual and normal mode)
- fix issue 22 (characterwise narrowing was brocken in last commit, reported
  by Matthew Boehm in https://github.com/chrisbra/NrrwRgn/issues/22, thanks!)
- in characterwise visual selection, trailing \n is not stripped when writing
  (reported by Matthew Boehm in https://github.com/chrisbra/NrrwRgn/23,
  thanks!)
- highlighting was wrong for characterwise visual selections
- update original window for multi narrowed regions (
  https://github.com/chrisbra/NrrwRgn/24, reported by Dane Summers, thanks!),
  use the g:nrrw_rgn_update_orig_win variable to enable
- error when narrowed window was moved to new tab and trying to quit
  (https://github.com/chrisbra/NrrwRgn/2, reported by Mario Ricalde, thanks!)
- better default names for the narrowed window
  (https://github.com/chrisbra/Nrrwrgn/28, reported by Mario Ricalde, thanks!)
- when setting g:nrrw_rgn_write_on_sync the original file will be saved,
  whenever the narrowed window is written back
  (https://github.com/chrisbra/26, reported by Mario Ricalde, thanks!)
- Some more error handling when using |:WidenRegion|
- Make sure highlighting is removed when using |:WidenRegion|

- when using single window narrowing, :w would jump back to the original window. Only do this, when 'hidden' is not set (reported by ping, thanks!)
- when narrowing a region, the last visual selected region wasn't correctly restored (reported by ping, thanks!)
- some code cleanup
- recursive narrowing was broken, fix it (reported by ping, thanks!)

NrrwRgn-0.29.vmb 29 2012-08-20 7.3 Christian Brabandt

NrrwRgn-0.20.vba 20 2011-07-25 7.3 Christian Brabandt - allow customization via the g:nrrw_topbot_leftright variable
  (Thanks Herbert Sitz!)
- allow what options will be applied using the g:nrrw_custom_options dict
  (suggested by Herbert Sitz. Thanks!)
- NRV didn't hightlight the region that was selected
  (reported by Herbert Sitz, Thanks- use the g:nrrw_rgn_protect variable, to prevent that the original buffer
  will be protected. This is useful, if you narrow several regions of the
  same buffer and want to write those changes indepentently
  (reported by kolyuchiy in https://github.com/chrisbra/NrrwRgn/issues/3,
  Thanks- fix an error with not correctly deleting the highlighted region, that was
  discovered when reporting issue 3 (see above).

(automatically uploaded)
NrrwRgn-0.18.vba 18 2010-12-11 7.3 Christian Brabandt Experimental version:
- experimental feature: Allow to Narrow several different regions at once using :g/pattern/NRP and afterwards calling :NRM (This only works linewise. Should that be made possible for any reagion?)
- disable folds, before writing changes back, otherwise chances are, you'll lose more data then wanted
- code cleanup
(automatically uploaded)
NrrwRgn-0.17.vba 17 2010-11-30 7.3 Christian Brabandt - cache the options, that will be set (instead of parsing
  $VIMRUNTIME/doc/options.txt everytime) in the Narrowed Window
- getting the options didn't work, when using an autocommand like this:
  autocmd BufEnter * cd %:p:h
  (reported by Hong Xu, Thanks!)
- :q didn't clean up the Narrowed Buffer correctly. Fix this
- some code cleanup
(automatically uploaded)
NrrwRgn-0.16.vba 16 2010-11-17 7.3 Christian Brabandt - Bugfix: copy all local options to the narrowed window (reported by Xu Hong, Thanks)
- Make :q quit the narrowed window correctly
(automatically uploaded)
NrrwRgn-0.15.vba 0.15 2010-08-26 7.2 Christian Brabandt -minor documentation update (reported by Hong Xu, Thanks!)
NrrwRgn-0.14.vba 0.14 2010-08-26 7.2 Christian Brabandt - Bugfix: :only in the original buffer resulted in errors (reported by Adam
  Monsen)
NrrwRgn-0.13.vba 0.13 2010-08-22 7.2 Christian Brabandt This adds the experimental feature of using the command :NUD to view a chunk of a unified diff in diff-mode
NrrwRgn-0.12.vba 0.12 2010-07-28 7.0 Christian Brabandt The Vimball for Version 0.11 contained some garbage that causes various errors.. So this Version is a new packaged version and should work now. Not sure how that happened.
(Thanks Dennis Hostetler!)
NrrwRgn-0.11.vba 0.11 2010-07-28 7.0 Christian Brabandt Don't set 'winfixwidth' and 'winfixheight'
NrrwRgn-0.10.vba 0.10 2010-05-20 7.0 Christian Brabandt - Restore Cursorposition using winrestview() and winsaveview()
- fix a bug, that prevented the use of visual narrowing
- Make sure when closing the narrowed buffer, the content will be written to
  the right original region
- use topleft for opening the Narrowed window
- check, that the original buffer is still available
- If you Narrow the complete buffer using :NRV and write the changes back, an
  additional trailing line is inserted. Remove that line.
- When writing the changes back, update the highlighting.
NrrwRgn-0.9.vba 0.9 2010-05-20 7.0 Christian Brabandt - It is now possible to Narrow a window recursively. This allows to have
  several narrowed windows, and allows for example to only diff certain
  regions (as was suggested in a recent thread at the vim_use mailinglist:
  http://groups.google.com/group/vim_use/msg/05d7fd9bd1556f0e) therefore, the
  use for the g:nrrw_rgn_sepwin variable isn't necessary anymore.
- Small documentation updates
NrrwRgn-0.8.vba 0.8 2010-05-18 7.0 Christian Brabandt - the g:nrrw_rgn_sepwin variable can be used to force seperate Narrowed Windows, so you could easily diff those windows.
- make the separating of several windows a little bit safer (look at the bufnr(), so it should work without problems for several buffers)
- switch from script local variables to buffer local variables, so narrowing for several buffers should work.
- set 'winfixheight' for narrowed window
- Added command :NRV (suggested by Charles Campbell, thanks!)
- added error handling, in case :NRV is called, without a selected region
- take care of beeps, when calling :NRV
- output WarningMsg
NrrwRgn-0.7.vba 0.7 2010-05-17 7.0 Christian Brabandt - really use the black hole register for deleting the old buffer contents in the narrowed buffer (suggestion by esquifit in http://groups.google.com/group/comp.editors/msg/3eb3e3a7c68597db)
- make autocommand nesting, so the highlighting will be removed when writing the buffer contents.
- Use g:nrrw_rgn_nohl variable to disable highlighting (as this can be disturbing).
NrrwRgn-0.6.vba 0.6 2010-05-04 7.0 Christian Brabandt Version 0.6:
- the previous version had problems restoring the orig buffer, this version fixes it (highlighting and setl ma did not work correctly)
Version 0.5 (unreleased):
- The mapping that allows for narrowing a visually selected range, did not work.  (Fixed!)
- Make :WidenRegion work as expected (close the widened window)
NrrwRgn-0.4.vba 0.4 2010-04-28 7.0 Christian Brabandt - Highlight narrowed region in the original buffer
- Save and Restore search-register
- Provide shortcut commands |:NR|
- Provide command |:NW| and |:NarrowWindow|
- Make plugin autoloadable
- Enable GLVS (see |:GLVS|)
- Provide Documenation (:h NarrowRegion)
- Distribute Plugin as vimball |pi_vimball.txt|
