Fixes: 3bda3fb60c ('nmtui: initial import of nmtui')
Previously, nmtui would set the newt color "checkbox" to a hard coded
value. This made it impossible to override the color via "$NEWT_COLORS".
With this change, nmtui also parses "$NEWT_COLORS" to allow setting
newt colors:
$ NEWT_COLORS='
window=white,red
border=white,red
checkbox=white,red
actcheckbox=white,green
' nmtui
Custom nmtui colors can now also be set via "$NMT_NEWT_COLORS":
"badLabel"
"plainLabel"
"disabledButton"
"textboxWithBackground"
For example:
$ NMT_NEWT_COLORS='plainLabel=green,lightgray' nmtui
The environment variables "$NEWT_COLORS_FILE" and "NMT_NEWT_COLORS_FILE"
are honored too.
The code is based on libnewt code ([1]), authored by Miroslav Lichvar.
That patch is originally LGPL-2.0-only licensed, but for inclusion in
NetworkManager we require it to be LGPL-2.1-or-later. Miroslav kindly
agreed to use his original contribution in NetworkManager.
