# nmtui: written by Wren Linux parts/network-manager.sh
# NetworkManager's text interface in Wren Linux's colors: white on black, the
# chosen line reversed. The same colors as the install list (install-extras.sh).
# Colors you set yourself in NEWT_COLORS win. The real program is
# /usr/bin/nmtui (WREN_NMTUI points somewhere else, for tests).
# A button is drawn in compactbutton colors until Tab reaches it, then in button colors:
# button is the reversed pair so the chosen one shows.
# newt (whiptail, nmtui) reads #rrggbb colors only when the terminal says it
# has 24-bit color (COLORTERM=truecolor); otherwise it ignores them all and
# draws its own blue and red, the chosen line hard to see. foot has 24-bit
# color, so it is said for it. The Linux console has none and gets color
# names (its black is black; foot's "black" is a dark teal). Every one of
# newt's color sets is given: one left out stays red.
# In foot the black behind it is "default", the terminal's own background:
# foot makes only that one see-through (the bar's windows are, colors.alpha),
# and an explicit #000000 is drawn solid black over it.
