| " Introduction | ||
| " ------------ | ||
| " | ||
| " This is a simple script that shows a tabs-like list of buffers in the bottom | ||
| " of the window. The biggest advantage of this script over various others is | ||
| " that it does not take any lines away from your terminal, leaving more space | ||
| " for the document you're editing. The tabs are only visible when you need | ||
| " them - when you are switchin between buffers. | ||
| " | ||
| " Usage | ||
| " ----- | ||
| " | ||
| " This script draws buffer tabs on vim startup, when a new buffer is created | ||
| " and when switching between buffers. | ||
| " | ||
| " It might be handy to create a few maps for easy switching of buffers in your | ||
| " .vimrc file. For example, using F1 and F2 keys: | ||
| " | ||
| " noremap <f1> :bprev<CR> | ||
| " noremap <f2> :bnext<CR> | ||
| " | ||
| " or using control-left and control-right keys: | ||
| " | ||
| " :noremap <C-left> :bprev<CR> | ||
| " :noremap <C-right> :bnext<CR> | ||
| " | ||
| " | ||
| " The following extra configuration variables are availabe: | ||
| " | ||
| " * g:buftabs_only_basename | ||
| " | ||
| " Define this variable to make buftabs only print the filename of each buffer, | ||
| " omitting the preceding directory name. Add to your .vimrc: | ||
| " | ||
| " :let g:buftabs_only_basename=1 | ||
| " | ||
| " | ||
| " * g:buftabs_in_statusline | ||
| " | ||
| " Define this variable to make the plugin show the buftabs in the statusline | ||
| " instead of the command line. It is a good idea to configure vim to show | ||
| " the statusline as well when only one window is open. Add to your .vimrc: | ||
| " | ||
| " set laststatus=2 | ||
| " :let g:buftabs_in_statusline=1 | ||
| " | ||
| " By default buftabs will take up the whole of the left-aligned section of | ||
| " your statusline. You can alternatively specify precisely where it goes | ||
| " using %{buftabs#statusline()} e.g.: | ||
| " | ||
| " set statusline=%=buffers:\ %{buftabs#statusline()} | ||
| " | ||
| " | ||
| " * g:buftabs_active_highlight_group | ||
| " * g:buftabs_inactive_highlight_group | ||
| " | ||
| " The name of a highlight group (:help highligh-groups) which is used to | ||
| " show the name of the current active buffer and of all other inactive | ||
| " buffers. If these variables are not defined, no highlighting is used. | ||
| " (Highlighting is only functional when g:buftabs_in_statusline is enabled) | ||
| " | ||
| " :let g:buftabs_active_highlight_group="Visual" | ||
| " | ||
| " | ||
| " * g:buftabs_marker_start [ | ||
| " * g:buftabs_marker_end ] | ||
| " * g:buftabs_separator - | ||
| " * g:buftabs_marker_modified ! | ||
| " | ||
| " These strings are drawn around each tab as separators, the 'marker_modified' | ||
| " symbol is used to denote a modified (unsaved) buffer. | ||
| " | ||
| " :let g:buftabs_separator = "." | ||
| " :let g:buftabs_marker_start = "(" | ||
| " :let g:buftabs_marker_end = ")" | ||
| " :let g:buftabs_marker_modified = "*" | ||
