Opps! +7.2.5 - Fix: + * Philip Morant suggested switching the command (bwipe) associated + with the 'd' key with the command (bdelete) associated with the 'D' + key. This made sense since the 'd' key is more likely to be used + compared to the 'D' key. +7.2.4 - Fix: + * I did not implement the patch provided by Godefroid Chapelle + correctly. I missed one line which happened to be the most + important one :) +7.2.3 - Enhancements: + * Thanks to David Fishburn for helping me out with a much needed + code overhaul as well as some awesome performance enhancements. + He also reworked the handling of tabs. + * Thanks to Vladimir Dobriakov for making the suggestions on + enhancing the documentation to include a better explaination of + what is contained in the main bufexplorer window. + * Thanks to Yuriy Ershov for added code that when the bufexplorer + window is opened, the cursor is now positioned at the line with the + active buffer (useful in non-MRU sort modes). + * Yuriy also added the abiltiy to cycle through the sort fields in + reverse order. + Fixes: + * Thanks to Michael Henry for supplying a patch that allows + bufexplorer to be opened even when there is one buffer or less. + * Thanks to Godefroid Chapelle for supplying a patch that fixed + MRU sort order after loading a session. +7.2.2 - Fixes: + * Thanks to David L. Dight for spotting and fixing an issue when + using ctrl^. bufexplorer would incorrectly handle the previous + buffer so that when ctrl^ was pressed the incorrect file was opened. +7.2.1 - Fixes: + * Thanks to Dimitar for spotting and fixing a feature that was + inadvertently left out of the previous version. The feature was + when bufexplorer was used together with WinManager, you could use + the tab key to open a buffer in a split window. +7.2.0 - Enhancements: + * For all those missing the \bs and \bv commands, these have now + returned. Thanks to Phil O'Connell for asking for the return of + these missing features and helping test out this version. + Fixes: + * Fixed problem with the bufExplorerFindActive code not working + correctly. + * Fixed an incompatibility between bufexplorer and netrw that caused + buffers to be incorrectly removed from the MRU list. +7.1.7 - Fixes: + * TaCahiroy fixed several issues related to opening a buffer in a + tab. +7.1.6 - Fixes: + * Removed ff=unix from modeline in bufexplorer.txt. Found by Bill + McCarthy. +7.1.5 - Fixes: + * Could not open unnamed buffers. Fixed by TaCahiroy. +7.1.4 - Fixes: + * Sometimes when a file's path has 'white space' in it, extra buffers + would be created containing each piece of the path. i.e: + opening c:\document and settings\test.txt would create a buffer + named "and" and a buffer named "Documents". This was reported and + fixed by TaCa Yoss. +7.1.3 - Fixes: + * Added code to allow only one instance of the plugin to run at a + time. Thanks Dennis Hostetler. +7.1.2 - Fixes: + * Fixed a jumplist issue spotted by JiangJun. I overlooked the + 'jumplist' and with a couple calls to 'keepjumps', everything is + fine again. + * Went back to just having a plugin file, no autoload file. By having + the autoload, WinManager was no longer working and without really + digging into the cause, it was easier to go back to using just a + plugin file. +7.1.1 - Fixes: + * A problem spotted by Thomas Arendsen Hein. + When running Vim (7.1.94), error E493 was being thrown. + Enhancements: + * Added 'D' for 'delete' buffer as the 'd' command was a 'wipe' + buffer. +7.1.0 - Another 'major' update, some by Dave Larson, some by me. + * Making use of 'autoload' now to make the plugin load quicker. + * Removed '\bs' and '\bv'. These are now controlled by the user. The + user can issue a ':sp' or ':vs' to create a horizontal or vertical + split window and then issue a '\be' + * Added handling of tabs. +7.0.17 - Fixed issue with 'drop' command. + Various enhancements and improvements. +7.0.16 - Fixed issue reported by Liu Jiaping on non Windows systems, which was + ... + Open file1, open file2, modify file1, open bufexplorer, you get the + following error: + + --------8<-------- + Error detected while processing function + <SNR>14_StartBufExplorer..<SNR>14_SplitOpen: + line 4: + E37: No write since last change (add ! to override) + + But the worse thing is, when I want to save the current buffer and + type ':w', I get another error message: + E382: Cannot write, 'buftype' option is set + --------8<-------- + +7.0.15 - Thanks to Mark Smithfield for suggesting bufexplorer needed to handle + the ':args' command. +7.0.14 - Thanks to Randall Hansen for removing the requirement of terminal + versions to be recompiled with 'gui' support so the 'drop' command + would work. The 'drop' command is really not needed in terminal + versions. +7.0.13 - Fixed integration with WinManager. + Thanks to Dave Eggum for another update. + - Fix: The detailed help didn't display the mapping for toggling + the split type, even though the split type is displayed. + - Fixed incorrect description in the detailed help for toggling + relative or full paths. + - Deprecated s:ExtractBufferNbr(). Vim's str2nr() does the same + thing. + - Created a s:Set() function that sets a variable only if it hasn't + already been defined. It's useful for initializing all those + default settings. + - Removed checks for repetitive command definitions. They were + unnecessary. + - Made the help highlighting a little more fancy. + - Minor reverse compatibility issue: Changed ambiguous setting + names to be more descriptive of what they do (also makes the code + easier to follow): + Changed bufExplorerSortDirection to bufExplorerReverseSort + Changed bufExplorerSplitType to bufExplorerSplitVertical + Changed bufExplorerOpenMode to bufExplorerUseCurrentWindow + - When the BufExplorer window closes, all the file-local marks are + now deleted. This may have the benefit of cleaning up some of the + jumplist. + - Changed the name of the parameter for StartBufExplorer from + "split" to "open". The parameter is a string which specifies how + the buffer will be open, not if it is split or not. + - Deprecated DoAnyMoreBuffersExist() - it is a one line function + only used in one spot. + - Created four functions (SplitOpen(), RebuildBufferList(), + UpdateHelpStatus() and ReSortListing()) all with one purpose - to + reduce repeated code. + - Changed the name of AddHeader() to CreateHelp() to be more + descriptive of what it does. It now returns an array instead of + updating the window directly. This has the benefit of making the + code more efficient since the text the function returns is used a + little differently in the two places the function is called. + - Other minor simplifications. +7.0.12 - MAJOR Update. + This version will ONLY run with Vim version 7.0 or greater. + Dave Eggum has made some 'significant' updates to this latest + version: + - Added BufExplorerGetAltBuf() global function to be used in the + user’s rulerformat. + - Added g:bufExplorerSplitRight option. + - Added g:bufExplorerShowRelativePath option with mapping. + - Added current line highlighting. + - The split type can now be changed whether bufexplorer is opened + in split mode or not. + - Various major and minor bug fixes and speed improvements. + - Sort by extension. + Other improvements/changes: + - Changed the help key from '?' to <F1> to be more 'standard'. + - Fixed splitting of vertical bufexplorer window. + Hopefully I have not forgot something :) +7.0.11 - Fixed a couple of highlighting bugs, reported by David Eggum. He also + changed passive voice to active on a couple of warning messages. +7.0.10 - Fixed bug report by Xiangjiang Ma. If the 'ssl' option is set, + the slash character used when displaying the path was incorrect. +7.0.9 - Martin Grenfell found and eliminated an annoying bug in the + bufexplorer/winmanager integration. The bug was were an + annoying message would be displayed when a window was split or + a new file was opened in a new window. Thanks Martin! +7.0.8 - Thanks to Mike Li for catching a bug in the WinManager integration. + The bug was related to the incorrect displaying of the buffer + explorer's window title. +7.0.7 - Thanks to Jeremy Cowgar for adding a new enhancement. This + enhancement allows the user to press 'S', that is capital S, which + will open the buffer under the cursor in a newly created split + window. +7.0.6 - Thanks to Larry Zhang for finding a bug in the "split" buffer code. + If you force set g:bufExplorerSplitType='v' in your vimrc, and if you + tried to do a \bs to split the bufexplorer window, it would always + split horizontal, not vertical. He also found that I had a typeo in + that the variable g:bufExplorerSplitVertSize was all lower case in + the documentation which was incorrect. +7.0.5 - Thanks to Mun Johl for pointing out a bug that if a buffer was + modified, the '+' was not showing up correctly. +7.0.4 - Fixed a problem discovered first by Xiangjiang Ma. Well since I've + been using vim 7.0 and not 6.3, I started using a function (getftype) + that is not in 6.3. So for backward compatibility, I conditionaly use + this function now. Thus, the g:bufExplorerShowDirectories feature is + only available when using vim 7.0 and above. +7.0.3 - Thanks to Erwin Waterlander for finding a problem when the last + buffer was deleted. This issue got me to rewrite the buffer display + logic (which I've wanted to do for sometime now). + Also great thanks to Dave Eggum for coming up with idea for + g:bufExplorerShowDirectories. Read the above information about this + feature. +7.0.2 - Thanks to Thomas Arendsen Hein for finding a problem when a user + has the default help turned off and then brought up the explorer. An + E493 would be displayed. +7.0.1 - Thanks to Erwin Waterlander for finding a couple problems. + The first problem allowed a modified buffer to be deleted. Opps! The + second problem occurred when several files were opened, BufExplorer + was started, the current buffer was deleted using the 'd' option, and + then BufExplorer was exited. The deleted buffer was still visible + while it is not in the buffers list. Opps again! +7.0.0 - Thanks to Shankar R. for suggesting to add the ability to set + the fixed width (g:bufExplorerSplitVertSize) of a new window + when opening bufexplorer vertically and fixed height + (g:bufExplorerSplitHorzSize) of a new window when opening + bufexplorer horizontally. By default, the windows are normally + split to use half the existing width or height. +6.3.0 - Added keepjumps so that the jumps list would not get cluttered with + bufexplorer related stuff. +6.2.3 - Thanks to Jay Logan for finding a bug in the vertical split position + of the code. When selecting that the window was to be split + vertically by doing a '\bv', from then on, all splits, i.e. '\bs', + were split vertically, even though g:bufExplorerSplitType was not set + to 'v'. +6.2.2 - Thanks to Patrik Modesto for adding a small improvement. For some + reason his bufexplorer window was always showing up folded. He added + 'setlocal nofoldenable' and it was fixed. +6.2.1 - Thanks goes out to Takashi Matsuo for added the 'fullPath' sorting + logic and option. +6.2.0 - Thanks goes out to Simon Johann-Ganter for spotting and fixing a + problem in that the last search pattern is overridden by the search + pattern for blank lines. +6.1.6 - Thanks to Artem Chuprina for finding a pesky bug that has been around + for sometime now. The <esc> key mapping was causing the buffer + explored to close prematurely when vim was run in an xterm. The <esc> + key mapping is now removed. +6.1.5 - Thanks to Khorev Sergey. Added option to show default help or not. +6.1.4 - Thanks goes out to Valery Kondakoff for suggesting the addition of + setlocal nonumber and foldcolumn=0. This allows for line numbering + and folding to be turned off temporarily while in the explorer. +6.1.3 - Added folding. Did some code cleanup. Added the ability to force the + newly split window to be temporarily vertical, which was suggested by + Thomas Glanzmann. +6.1.2 - Now pressing the <esc> key will quit, just like 'q'. + Added folds to hide winmanager configuration. + If anyone had the 'C' option in their cpoptions they would receive + a E10 error on startup of BufExplorer. cpo is now saved, updated and + restored. Thanks to Charles E Campbell, Jr. + Attempted to make sure there can only be one BufExplorer window open + at a time. +6.1.1 - Thanks to Brian D. Goodwin for adding toupper to FileNameCmp. This + way buffers sorted by name will be in the correct order regardless of + case. +6.0.16 - Thanks to Andre Pang for the original patch/idea to get bufexplorer + to work in insertmode/modeless mode (evim). Added Initialize + and Cleanup autocommands to handle commands that need to be + performed when starting or leaving bufexplorer. +6.0.15 - Srinath Avadhanulax added a patch for winmanager.vim. +6.0.14 - Fix a few more bug that I thought I already had fixed. Thanks + to Eric Bloodworth for adding 'Open Mode/Edit in Place'. Added + vertical splitting. +6.0.13 - Thanks to Charles E Campbell, Jr. for pointing out some embarrassing + typos that I had in the documentation. I guess I need to run + the spell checker more :o) +6.0.12 - Thanks to Madoka Machitani, for the tip on adding the augroup command + around the MRUList autocommands. +6.0.11 - Fixed bug report by Xiangjiang Ma. '"=' was being added to the + search history which messed up hlsearch. +6.0.10 - Added the necessary hooks so that the Srinath Avadhanula's + winmanager.vim script could more easily integrate with this script. + Tried to improve performance. +6.0.9 - Added MRU (Most Recently Used) sort ordering. +6.0.8 - Was not resetting the showcmd command correctly. + Added nifty help file. +6.0.7 - Thanks to Brett Carlane for some great enhancements. Some are added, + some are not, yet. Added highlighting of current and alternate + filenames. Added splitting of path/filename toggle. Reworked + ShowBuffers(). + Changed my email address. +6.0.6 - Copyright notice added. Needed this so that it could be distributed + with Debian Linux. Fixed problem with the SortListing() function + failing when there was only one buffer to display. +6.0.5 - Fixed problems reported by David Pascoe, in that you where unable to + hit 'd' on a buffer that belonged to a files that no longer existed + and that the 'yank' buffer was being overridden by the help text when + the bufexplorer was opened. +6.0.4 - Thanks to Charles Campbell, Jr. for making this plugin more plugin + *compliant*, adding default keymappings of <Leader>be and <Leader>bs + as well as fixing the 'w:sortDirLabel not being defined' bug. +6.0.3 - Added sorting capabilities. Sort taken from explorer.vim. +6.0.2 - Can't remember.
