Tabulous

Lightweight Vim plugin to enhance the tabline including numbered tab page labels; it's written entirely in Vim script.

Features

Shows the tab page number on every tab label for quickly navigating to the desired tab <number>gt. Rename the current tab page label. Tabs display an indicator when a buffer has been modified and not saved. Dynamically updates the filename of the currently focused window in the tab page. Eliminates inefficient use of string concatenation operator by using printf where possible. Does not show filename extensions to preserve the amount of tab label space. Performs runtime calculation of maximum tab label length and truncates accordingly (Dynamic resizing of tab labels). Options are configurable from .vimrc.

Planned Features

Enhancement of tab label truncation algorithm Toggle tab page numbers on and off by keyboard shortcut Toggle tab label filename extensions on and off by keyboard shortcut Toggle tab label truncation on and off by keyboard shortcut

In progress: keyboard shortcuts and enhancement of tab label truncation algorithm.
