workspace.vim

This plugin gives each tabpage it's own buffer list.

The idea is to make it easier to manage large number of buffers by keeping them grouped separately in workspaces.

Each tabpage represents a workspace with it's own buffer list.
Workspaces are numbered starting with 1, like tabpages, but their numbers remain static as they are opened and closed — don't conflate these two sets of numbers.
:ls, :bn, :bp will use buffers from current workspace. Third party buffer switchers should work as is.

Installation

Copy workspace.vim file to vim plugin directory.
Enable hidden option.
Add globals to sessionoptions option (for session saving/loading).
See bellow for sample vimrc snippet.

Usage

Command	Description
`:WS n`	Switch to workspace `n` (it is a number). Create it, when necessary.
`:WSc [n]`	Close current workspace or `n`.
`:WSmv n`	Rename current workspace to `n`.
`:WSbmv n`	Move current buffer to workspace `n`.
`:WSbrm [n]`	Remove buffer from current workspace. Or delete it, if it is open in only current workspace.

All commands try to preserve window layout, while handling buffers.

Updates to vimrc

Sample snippet for vimrc to setup options and mappings:

" Plugin needs these options
set hidden
set sessionoptions+=globals

" Switch among workspaces 1 through 10
map <silent> <leader>1 :WS 1<CR>
map <silent> <leader>2 :WS 2<CR>
map <silent> <leader>3 :WS 3<CR>
map <silent> <leader>4 :WS 4<CR>
map <silent> <leader>5 :WS 5<CR>
map <silent> <leader>6 :WS 6<CR>
map <silent> <leader>7 :WS 7<CR>
map <silent> <leader>8 :WS 8<CR>
map <silent> <leader>9 :WS 9<CR>
map <silent> <leader>0 :WS 10<CR>

" Alternate between current and previous workspaces
map <silent> <leader>` :call WS_Backforth()<CR>

" Show info line about workspaces
map <silent> <leader><space> :call WS_Line()<CR>
