examples/statusbar_demo
Status bar demo — a beautiful full-width bottom status bar composed from
coloured segments with gleamtea/style, pinned to the last terminal row.
A left mode badge + filename, an elastic filler, and right-aligned position,
encoding and a beamtea badge. i enters INSERT, Esc returns to NORMAL,
arrows move the cursor, q quits.
Run: ./bin/gleamtea-run statusbar_demo
