The existing color code escape sequences required the user to set the
color, write the string, then unset with COLOR_OFF. Instead the macros
can be made to take the string itself and automatically terminate the
color with COLOR_OFF. This makes for much more concise strings.
There was no easy to use API for printing the contents of a table, and
was left up to the caller to handle manually. This adds display_table_row
which makes displaying tables much easier, including automatic support
for line truncation and continuation on the next line.
Lines which are too long will be truncated and displayed on the next
line while also taking into account any colored output. This works with any
number of columns.
This removes the need for the module to play games with encoding newlines
and tabs to make the output look nice.
As a start, this functionality was added to the command display.
\e[1;30m is bold black, often, but not always displayed bright black or
bold bright black. In case it is displayed as real black it is
invisible. \e[1;90m is explicit bold bright black.
\e[37m is white, therefore it is not suitable to be labeled as GREY,
which is \e[90m
This takes a Dbus iterator which has been entered into a
dictionary and prints out each key and value. It requires
a mapping which maps keys to types and units. For simple
cases the mapping will consist of a dbus type character
and a units string, e.g. dBm, Kbit/s etc. For more complex
printing which requires processing the value the 'units'
void* cant be set to a function which can be custom written
to handle the value.
The display refresh is automatically enabled or disabled depending on
the width of the window. This allows to avoid the incorrect display on
refresh for the small windows.
