barline is a small data collector that is designed to function between lemonbar and bspwm. It sources data from bspwm and system data such as cpu usage, memory usage, temperature, etc. It uses a lemonbar like syntax for its format and passes any unknown directive to lemonbar.
barline is configured via the '~/.config/barline/barlinerc' file in your home directory. Below is an example from my 'barlinerc' and further down is a table of supported blocks.
format %{l}%{W}%{c}%{N}%{r}cpu: %{C} • temp: %{Pthermal_zone1:60} • mem: %{M} • vol: %{V} • wlan: %{Lwlp8s0} • batt: %{EBAT1} • %{DAmerica/New_York}

Blocks are delimited by %{ and } and are formatted with the first parameter right after the block type and further parameters separated by :. Any number of trailing parameters are optional and are assumed to be the default. Unknown blocks are passed directly to lemonbar.

Memory Usage | type ('U' = used, 'A' = available, 'T' = total), warn (percentage high) | %{MU:0.85} |
%{P} |
Temperature | name, warn (value high) | %{Pthermal_zone0:-1} |
%{D} |
Time and Date | timezone (empty for system setting), format (strftime format) | %{D:%R} |
