" 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 S<>bastien 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
