+" Name Of File: minibufexpl.vim
+" Description: Mini Buffer Explorer Vim Plugin
+" Maintainer: Bindu Wavell <bindu@wavell.net>
+" URL: http://vim.sourceforge.net/scripts/script.php?script_id=159
+" Last Change: Sunday, June 21, 2004
+" Version: 6.3.2
+" Derived from Jeff Lanzarotta's bufexplorer.vim version 6.0.7
+" Jeff can be reached at (jefflanzarotta@yahoo.com) and the
+" original plugin can be found at:
+" http://lanzarotta.tripod.com/vim/plugin/6/bufexplorer.vim.zip
+"
+" Usage: Normally, this file should reside in the plugins
+" directory and be automatically sourced. If not, you must
+" manually source this file using ':source minibufexplorer.vim'.
+"
+" You may use the default keymappings of
+"
+" <Leader>mbe - Opens MiniBufExplorer
+"
+" or you may want to add something like the following
+" key mapping to your _vimrc/.vimrc file.
+"
+" map <Leader>b :MiniBufExplorer<cr>
+"
+" However, in most cases you won't need any key-bindings at all.
+"
+" <Leader> is usually backslash so type "\mbe" (quickly) to open
+" the -MiniBufExplorer- window.
+"
+" Other keymappings include: <Leader>mbc to close the Explorer
+" window, <Leader>mbu to force the Explorer to Update and
+" <Leader>mbt to toggle the Explorer window; it will open if
+" closed or close if open. Each of these key bindings can be
+" overridden (see the notes on <Leader>mbe above.)
+"
+" You can map these additional commands as follows:
+"
+" map <Leader>c :CMiniBufExplorer<cr>
+" map <Leader>u :UMiniBufExplorer<cr>
+" map <Leader>t :TMiniBufExplorer<cr>
+"
+" NOTE: you can change the key binding used in these mappings
+" so that they fit with your configuration of vim.
+"
+" You can also call each of these features by typing the
+" following in command mode:
+"
+" :MiniBufExplorer " Open and/or goto Explorer
+" :CMiniBufExplorer " Close the Explorer if it's open
+" :UMiniBufExplorer " Update Explorer without navigating
+" :TMiniBufExplorer " Toggle the Explorer window open and
+" closed.
+"
+" To control where the new split window goes relative to the
+" current window, use the setting:
+"
+" let g:miniBufExplSplitBelow=0 " Put new window above
+" " current or on the
+" " left for vertical split
+" let g:miniBufExplSplitBelow=1 " Put new window below
+" " current or on the
+" " right for vertical split
+"
+" The default for this is read from the &splitbelow VIM option.
+"
+" By default we are now (as of 6.0.2) forcing the -MiniBufExplorer-
+" window to open up at the edge of the screen. You can turn this
+" off by setting the following variable in your .vimrc:
+"
+" let g:miniBufExplSplitToEdge = 0
+"
+" If you would like a vertical explorer you can assign the column
+" width (in characters) you want for your explorer window with the
+" following .vimrc variable (this was introduced in 6.3.0):
+"
+" let g:miniBufExplVSplit = 20 " column width in chars
+"
+" IN HORIZONTAL MODE:
+" It is now (as of 6.1.1) possible to set a maximum height for
+" the -MiniBufExplorer- window. You can set the max height by
+" letting the following variable in your .vimrc:
+"
+" let g:miniBufExplMaxSize = <max lines: defualt 0>
+"
+" setting this to 0 will mean the window gets as big as
+" needed to fit all your buffers.
+"
+" NOTE: This was g:miniBufExplMaxHeight before 6.3.0; the old
+" setting is backwards compatible if you don't use MaxSize.
+"
+" As of 6.2.2 it is possible to set a minimum height for the
+" -MiniBufExplorer- window. You can set the min height by
+" letting the following variable in your .vimrc:
+"
+" let g:miniBufExplMinSize = <min height: default 1>
+"
+" NOTE: This was g:miniBufExplMinHeight before 6.3.0; the old
+" setting is backwards compatible if you don't use MinSize.
+"
+" IN VERTICAL MODE: (as of 6.3.0)
+" By default the vertical explorer has a fixed width. If you put:
+"
+" let g:miniBufExplMaxSize = <max width: default 0>
+"
+" into your .vimrc then MBE will attempt to set the width of the
+" MBE window to be as wide as your widest tab. The width will not
+" exceed MaxSize even if you have wider tabs.
+"
+" Accepting the default value of 0 for this will give you a fixed
+" width MBE window.
+"
+" You can specify a MinSize for the vertical explorer window by
+" putting the following in your .vimrc:
+"
+" let g:miniBufExplMinSize = <min width: default 1>
+"
+" This will have no effect unless you also specivy MaxSize.
+"
+" By default we are now (as of 6.0.1) turning on the MoreThanOne
+" option. This stops the -MiniBufExplorer- from opening
+" automatically until more than one eligible buffer is available.
+" You can turn this feature off by setting the following variable
+" in your .vimrc:
+"
+" let g:miniBufExplorerMoreThanOne=1
+"
+" (The following enhancement is as of 6.2.2)
+" Setting this to 0 will cause the MBE window to be loaded even
+" if no buffers are available. Setting it to 1 causes the MBE
+" window to be loaded as soon as an eligible buffer is read. You
+" can also set it to larger numbers. So if you set it to 4 for
+" example the MBE window wouldn't auto-open until 4 eligibles
+" buffers had been loaded. This is nice for folks that don't
+" want an MBE window unless they are editing more than two or
+" three buffers.
+"
+" To enable the optional mapping of Control + Vim Direction Keys
+" [hjkl] to window movement commands, you can put the following into
+" your .vimrc:
+"
+" let g:miniBufExplMapWindowNavVim = 1
+"
+" To enable the optional mapping of Control + Arrow Keys to window
+" movement commands, you can put the following into your .vimrc:
+"
+" let g:miniBufExplMapWindowNavArrows = 1
+"
+" To enable the optional mapping of <C-TAB> and <C-S-TAB> to a
+" function that will bring up the next or previous buffer in the
+" current window, you can put the following into your .vimrc:
+"
+" let g:miniBufExplMapCTabSwitchBufs = 1
+"
+" To enable the optional mapping of <C-TAB> and <C-S-TAB> to mappings
+" that will move to the next and previous (respectively) window, you
+" can put the following into your .vimrc:
+"
+" let g:miniBufExplMapCTabSwitchWindows = 1
+"
+"
+" NOTE: If you set the ...TabSwitchBufs AND ...TabSwitchWindows,
+" ...TabSwitchBufs will be enabled and ...TabSwitchWindows
+" will not.
+"
+" As of MBE 6.3.0, you can put the following into your .vimrc:
+"
+" let g:miniBufExplUseSingleClick = 1
+"
+" If you would like to single click on tabs rather than double
+" clicking on them to goto the selected buffer.
+"
+" NOTE: If you use the single click option in taglist.vim you may
+" need to get an updated version that includes a patch I
+" provided to allow both explorers to provide single click
+" buffer selection.
+"
+" It is possible to customize the the highlighting for the tabs in
+" the MBE by configuring the following highlighting groups:
+"
+" MBENormal - for buffers that have NOT CHANGED and
+" are NOT VISIBLE.
+" MBEChanged - for buffers that HAVE CHANGED and are
+" NOT VISIBLE
+" MBEVisibleNormal - buffers that have NOT CHANGED and are
+" VISIBLE
+" MBEVisibleChanged - buffers that have CHANGED and are VISIBLE
+"
+" You can either link to an existing highlighting group by
+" adding a command like:
+"
+" hi link MBEVisibleChanged Error
+"
+" to your .vimrc or you can specify exact foreground and background
+" colors using the following syntax:
+"
+" hi MBEChanged guibg=darkblue ctermbg=darkblue termbg=white
+"
+" NOTE: If you set a colorscheme in your .vimrc you should do it
+" BEFORE updating the MBE highlighting groups.
+"
+" If you use other explorers like TagList you can (As of 6.2.8) put:
+"
+" let g:miniBufExplModSelTarget = 1
+"
+" into your .vimrc in order to force MBE to try to place selected
+" buffers into a window that does not have a nonmodifiable buffer.
+" The upshot of this should be that if you go into MBE and select
+" a buffer, the buffer should not show up in a window that is
+" hosting an explorer.
+"
+" There is a VIM bug that can cause buffers to show up without
+" their highlighting. The following setting will cause MBE to
+" try and turn highlighting back on (introduced in 6.3.1):
+"
+" let g:miniBufExplForceSyntaxEnable = 1
+"
+" MBE has had a basic debugging capability for quite some time.
+" However, it has not been very friendly in the past. As of 6.0.8,
+" you can put one of each of the following into your .vimrc:
+"
+" let g:miniBufExplorerDebugLevel = 0 " MBE serious errors output
+" let g:miniBufExplorerDebugLevel = 4 " MBE all errors output
+" let g:miniBufExplorerDebugLevel = 10 " MBE reports everything
+"
+" You can also set a DebugMode to cause output to be target as
+" follows (default is mode 3):
+"
+" let g:miniBufExplorerDebugMode = 0 " Errors will show up in
+" " a vim window
+" let g:miniBufExplorerDebugMode = 1 " Uses VIM's echo function
+" " to display on the screen
+" let g:miniBufExplorerDebugMode = 2 " Writes to a file
+" " MiniBufExplorer.DBG
+" let g:miniBufExplorerDebugMode = 3 " Store output in global:
+" " g:miniBufExplorerDebugOutput
+"
+" Or if you are able to start VIM, you might just perform these
+" at a command prompt right before you do the operation that is
+" failing.
+"
+" History: Moved to end of file
+"
+" Known Issues: When debugging is turned on and set to output to a window, there
+" are some cases where the window is opened more than once, there
+" are other cases where an old debug window can be lost.
+"
+" Several MBE commands can break the window history so <C-W>[pnw]
+" might not take you to the expected window.
+"
+" Todo: Add the ability to specify a regexp for eligible buffers
+" allowing the ability to filter out certain buffers that
+" you don't want to control from MBE

+" MBE Script History {{{
+"=============================================================================
+"
+" History: 6.3.2 o For some reason there was still a call to StopExplorer
+" with 2 params. Very old bug. I know I fixed before,
+" any way many thanks to Jason Mills for reporting this!
+" 6.3.1 o Include folds in source so that it's easier to
+" navigate.
+" o Added g:miniBufExplForceSyntaxEnable setting for folks
+" that want a :syntax enable to be called when we enter
+" buffers. This can resolve issues caused by a vim bug
+" where buffers show up without highlighting when another
+" buffer has been closed, quit, wiped or deleted.
+" 6.3.0 o Added an option to allow single click (rather than
+" the default double click) to select buffers in the
+" MBE window. This feature was requested by AW Law
+" and was inspired by taglist.vim. Note that you will
+" need the latest version of taglist.vim if you want to
+" use MBE and taglist both with singleclick turned on.
+" Also thanks to AW Law for pointing out that you can
+" make an Explorer not be listed in a standard :ls.
+" o Added the ability to have your tabs show up in a
+" vertical window rather than the standard horizontal
+" one. Just let g:miniBufExplVSplit = <width> in your
+" .vimrc and your will get this functionality.
+" o If you use the vertical explorer and you want it to
+" autosize then let g:miniBufExplMaxSize = <max width>
+" in your .vimrc. You may use the MinSize letting in
+" addition to the MaxLetting if you don't want a super
+" thin window.
+" o g:miniBufExplMaxHeight was renamed g:miniBufExplMaxSize
+" g:miniBufExplMinHeight was renamed g:miniBufExplMinSize
+" the old settings are backwards compatible if you don't
+" use the new settings, but they are depreciated.
+" 6.2.8 o Add an option to stop MBE from targeting non-modifiable
+" buffers when switching buffers. Thanks to AW Law for
+" the inspiration for this. This may not work if a user
+" has lots of explorer/help windows open.
+" 6.2.7 o Very minor bug fix for people who want to set
+" loaded_minibufexplorer in their .vimrc in order to
+" stop MBE from loading. 99.99% of users do not need
+" this update.
+" 6.2.6 o Moved history to end of source file
+" o Updated highlighting documentation
+" o Created global commands MBEbn and MBEbp that can be
+" used in mappings if folks want to cycle buffers while
+" skipping non-eligible buffers.
+" 6.2.5 o Added <Leader>mbt key mapping which will toggle
+" the MBE window. I map this to F3 in my .vimrc
+" with "map <F3> :TMiniBufExplorer<CR>" which
+" means I can easily close the MBE window when I'm
+" not using it and get it back when I want it.
+" o Changed default debug mode to 3 (write to global
+" g:miniBufExplorerDebugOutput)
+" o Made a pass through the documentation to clarify
+" serveral issues and provide more complete docs
+" for mappings and commands.
+" 6.2.4 o Because of the autocommand switch (see 6.2.0) it
+" was possible to remove the restriction on the
+" :set hidden option. It is now possible to use
+" this option with MBE.
+" 6.2.3 o Added miniBufExplTabWrap option. It is turned
+" off by default. When turned on spaces are added
+" between tabs and gq} is issued to perform line
+" formatting. This won't work very well if filenames
+" contain spaces. It would be pretty easy to write
+" my own formatter, but I'm too lazy, so if someone
+" really needs that feature I'll add it :)
+" 6.2.2 o Changed the way the g:miniBufExplorerMoreThanOne
+" global is handled. You can set this to the number
+" of eligible buffers you want to be loaded before
+" the MBE window is loaded. Setting it to 0 causes
+" the MBE window to be opened even if there are no
+" buffers. Setting it to 4 causes the window to stay
+" closed until the 4th eligible buffer is loaded.
+" o Added a MinHeight option. This is nice if you want
+" the MBE window to always take the same amount of
+" space. For example set MaxSize and MinSize to 2
+" and set MoreThanOne to 0 and you will always have
+" a 2 row (plus the ruler :) MBE window.
+" NOTE: in 6.3.0 we started using MinSize instead of
+" Minheight. This will still work if MinSize is not
+" specified, but it is depreciated. Use MinSize instead.
+" o I now setlocal foldcomun=0 and nonumber in the MBE
+" window. This is for those of you that like to have
+" these options turned on locally. I'm assuming noone
+" outthere wants foldcolumns and line numbers in the
+" MBE window? :)
+" o Fixed a bug where an empty MBE window was taking half
+" of the screen (partly why the MinHeight option was
+" added.)
+" 6.2.1 o If MBE is the only window (because of :bd for example)
+" and there are still eligible buffers then one of them
+" will be displayed.
+" o The <Leader>mbe mapping now highlights the buffer from
+" the current window.
+" o The delete ('d') binding in the MBE window now restors
+" the cursor position, which can help if you want to
+" delete several buffers in a row that are not at the
+" beginning of the buffer list.
+" o Added a new key binding ('p') in the MBE window to
+" switch to the previous window (last edit window)
+" 6.2.0 o Major overhaul of autocommand and list updating code,
+" we now have much better handling of :bd (which is the
+" most requested feature.) As well as resolving other
+" issues where the buffer list would not be updated
+" automatically. The old version tried to trap specific
+" events, this one just updates frequently, but it keeps
+" track and only changes the screen if there has been
+" a change.
+" o Added g:miniBufExplMaxHeight variable so you can keep
+" the -MiniBufExplorer- window small when you have lots
+" of buffers (or buffers with long names :)
+" NOTE: in 6.3.0 we started using MaxSize instead of
+" MaxHeight. This will still work if MaxSize is not
+" specified, but it is depreciated. Use MaxSize instead.
+" o Improvement to internal syntax highlighting code
+" I renamed the syntax group names. Anyone who has
+" figured out how to use them already shouldn't have
+" any trouble with the new Nameing :)
+" o Added debug mode 3 which writes to a global variable
+" this is fast and doesn't mess with the buffer/window
+" lists.
+" 6.1.0 o <Leader>mbc was failing because I was calling one of
+" my own functions with the wrong number of args. :(
+" Thanks to Gerry Patterson for finding this!
+" This code is very stable (although it has some
+" idiocyncracies.)
+" 6.0.9 o Double clicking tabs was overwriting the cliboard
+" register on MS Windows. Thanks to Shoeb Bhinderwala
+" for reporting this issue.
+" 6.0.8 o Apparently some VIM builds are having a hard time with
+" line continuation in scripts so the few that were here
+" have been removed.
+" o Generalized FindExplorer and FindCreateExplorer so
+" that they can be used for the debug window. Renaming
+" to FindWindow and FindCreateWindow.
+" o Updated debugging code so that debug output is put into
+" a buffer which can then be written to disk or emailed
+" to me when someone is having a major issue. Can also
+" write directly to a file (VERY SLOWLY) on UNIX or Win32
+" (not 95 or 98 at the moment) or use VIM's echo function
+" to display the output to the screen.
+" o Several people have had issues when the hidden option
+" is turned on. So I have put in several checks to make
+" sure folks know this if they try to use MBE with this
+" option set.
+" 6.0.7 o Handling BufDelete autocmd so that the UI updates
+" properly when using :bd (rather than going through
+" the MBE UI.)
+" o The AutoUpdate code will now close the MBE window when
+" there is a single eligible buffer available.
+" This has the usefull side effect of stopping the MBE
+" window from blocking the VIM session open when you close
+" the last buffer.
+" o Added functions, commands and maps to close & update
+" the MBE window (<leader>mbc and <leader>mbu.)
+" o Made MBE open/close state be sticky if set through
+" StartExplorer(1) or StopExplorer(1), which are
+" called from the standard mappings. So if you close
+" the mbe window with \mbc it won't be automatically
+" opened again unless you do a \mbe (or restart VIM).
+" o Removed spaces between "tabs" (even more mini :)
+" o Simplified MBE tab processing
+" 6.0.6 o Fixed register overwrite bug found by Sébastien Pierre
+" 6.0.5 o Fixed an issue with window sizing when we run out of
+" buffers.
+" o Fixed some weird commenting bugs.
+" o Added more optional fancy window/buffer navigation:
+" o You can turn on the capability to use control and the
+" arrow keys to move between windows.
+" o You can turn on the ability to use <C-TAB> and
+" <C-S-TAB> to open the next and previous (respectively)
+" buffer in the current window.
+" o You can turn on the ability to use <C-TAB> and
+" <C-S-TAB> to switch windows (forward and backwards
+" respectively.)
+" 6.0.4 o Added optional fancy window navigation:
+" o Holding down control and pressing a vim direction
+" [hjkl] will switch windows in the indicated direction.
+" 6.0.3 o Changed buffer name to -MiniBufExplorer- to resolve
+" Issue in filename pattern matching on Windows.
+" 6.0.2 o 2 Changes requested by Suresh Govindachar:
+" o Added SplitToEdge option and set it on by default
+" o Added tab and shift-tab mappings in [MBE] window
+" 6.0.1 o Added MoreThanOne option and set it on by default
+" MiniBufExplorer will not automatically open until
+" more than one eligible buffers are opened. This
+" reduces cluter when you are only working on a
+" single file.
+" NOTE: See change log for 6.2.2 for more details about
+" this feature
+" 6.0.0 o Initial Release on November 20, 2001
