" Name Of File: lusty-juggler.vim
" Description: Dynamic Buffer Switcher Vim Plugin
" Maintainer: Stephen Bach
" Contributors: Juan Frias, Bartosz Leper, Marco Barberis, Vincent Driessen,
" Martin Wache, Johannes Holzfuß, Adam Rutkowski, Carlo Teubner,
" lilydjwg, Leonid Shevtsov, Giuseppe Rota, Göran Gustafsson,
" Chris Lasher, Guy Haskin Fernald, Thibault Duplessis,
" Gabriel Pettier, Ross Lagerwall, John Szakmeister
"
" Release Date: July 24, 2018
" Version: 1.6
"
" Usage:
" <Leader>lj - Opens the buffer juggler.
"
" You can also use this command:
"
" ":LustyJuggler"
"
" To suppress the default mapping, set this option:
"
" let g:LustyJugglerDefaultMappings = 0
"
" When launched, the command bar at bottom is replaced with a
" new bar showing the names of currently-opened buffers in
" most-recently-used order.
"
" By default, LustyJuggler follows the QWERTY layout, and
" buffers are mapped to these keys:
"
" 1st|2nd|3rd|4th|5th|6th|7th|8th|9th|10th
" ----------------------------------------
" a s d f g h j k l ;
" 1 2 3 4 5 6 7 8 9 0
"
" So if you type "f" or "4", the fourth buffer name will be
" highlighted and the bar will shift to center it as necessary
" (and show more of the buffer names on the right).
"
" If you want to switch to that buffer, press "f" or "4" again
" or press "<ENTER>". Alternatively, press one of the other
" mapped keys to highlight another buffer. To open the buffer
" in a new split, press "b" for horizontal or "v" for vertical.
"
" To display the key with the name of the buffer, add one of
" the following lines to your .vimrc:
"
" let g:LustyJugglerShowKeys = 'a' (for alpha characters)
" let g:LustyJugglerShowKeys = 1 (for digits)
"
" To cancel the juggler, press any of "q", "<ESC>", "<C-c",
" "<BS>", "<Del>", or "<C-h>".
"
" LustyJuggler also supports the Dvorak, Colemak, Bépo and aerty
" keyboard layouts. To enable this feature, place the one of the
" following in your .vimrc:
"
" let g:LustyJugglerKeyboardLayout = "dvorak"
" let g:LustyJugglerKeyboardLayout = "colemak"
" let g:LustyJugglerKeyboardLayout = "bépo"
" let g:LustyJugglerKeyboardLayout = "azerty"
"
" With the layout set to "dvorak", the buffer mapping is as
" follows:
"
" 1st|2nd|3rd|4th|5th|6th|7th|8th|9th|10th
" ----------------------------------------
" a o e u i d h t n s
" 1 2 3 4 5 6 7 8 9 0
"
" With the layout set to "colemak", the buffer mapping is as
" follows:
"
" 1st|2nd|3rd|4th|5th|6th|7th|8th|9th|10th
" ----------------------------------------
" a r s t d h n e i o
" 1 2 3 4 5 6 7 8 9 0
"
" With the layout set to "bépo", the buffer mapping is as
" follows:
"
" 1st|2nd|3rd|4th|5th|6th|7th|8th|9th|10th
" ----------------------------------------
" a u i e , t s r n m
" 1 2 3 4 5 6 7 8 9 0
"
" With the layout set to "azerty", the buffer mapping is as
" follows:
"
" 1st|2nd|3rd|4th|5th|6th|7th|8th|9th|10th
" ----------------------------------------
" q s d f g j k l m ù
" 1 2 3 4 5 6 7 8 9 0
"
" LustyJuggler can act very much like <A-Tab> window switching.
" To enable this mode, add the following line to your .vimrc:
"
" let g:LustyJugglerAltTabMode = 1
"
" Then, given the following mapping:
"
" noremap <silent> <A-s> :LustyJuggler<CR>
"
" Pressing "<A-s>" will launch the LustyJuggler with the
" previous buffer highlighted. Typing "<A-s>" again will cycle
" to the next buffer (in most-recently used order), and
" "<ENTER>" will open the highlighted buffer. For example, the
" sequence "<A-s><Enter>" will open the previous buffer, and
" "<A-s><A-s><Enter>" will open the buffer used just before the
" previous buffer, and so on.
"
" Bonus: This plugin also includes the following command, which will
" immediately switch to your previously used buffer:
"
" ":LustyJugglePrevious"
"
" This is similar to the ":b#" command, but accounts for the
" common situation where the previously used buffer (#) has
" been killed and is thus inaccessible. In that case, it will
" instead switch to the buffer used before that one (and on down
" the line if that buffer has been killed too).
"
"
" Install Details:
"
" Copy this file into $HOME/.vim/plugin directory so that it will be sourced
" on startup automatically.
"
" Note! This plugin requires Vim be compiled with Ruby interpretation. If you
" don't know if your build of Vim has this functionality, you can check by
" running "vim --version" from the command line and looking for "+ruby".
" Alternatively, just try sourcing this script.
"
" If your version of Vim does not have "+ruby" but you would still like to
" use this plugin, you can fix it. See the "Check for Ruby functionality"
" comment below for instructions.
"
" If you are using the same Vim configuration and plugins for multiple
" machines, some of which have Ruby and some of which don't, you may want to
" turn off the "Sorry, LustyJuggler requires ruby" warning. You can do so
" like this (in .vimrc):
"
" let g:LustyJugglerSuppressRubyWarning = 1

" TODO:
" - Add TAB recognition back.
" - Add option to open buffer immediately when mapping is pressed (but not
" release the juggler until the confirmation press).
" - Have the delimiter character settable.
" - have colours settable?
" Exit quickly when already loaded.
