oatbar-0.0.4 is not a library.
Oatbar
It is a standalone desktop bar that can be used with various WMs and DEs. This bar aims to become one of the most full-featured bars available.
- Flexibility and pluggability of information sources from existing ecosystems
- Arbitrary scripts
i3blocksformati3statusformat- PNG image embedding that could be rendered by a source script at runtime.
- External plugins are preferred, but the most basic modules are embedded: EWHM, layouts, clock, etc.
- Conversion of string sources to other types (numbers, bytes, percentages) that could be rendered by specialize widgets
- Native Pango markup support
- Source data cleaning via regexes so inflexible source module data can be cleaned inside of the
oatbar.
