+separator::
+ A boolean which specifies whether a separator line should be drawn
+ after this block. The default is true, meaning the separator line will
+ be drawn. Note that if you disable the separator line, there will still
+ be a gap after the block, unless you also use +separator_block_width+.
+separator_block_width::
+ The amount of pixels to leave blank after the block. In the middle of
+ this gap, a separator line will be drawn unless +separator+ is
+ disabled. Normally, you want to set this to an odd value (the default
+ is 9 pixels), since the separator line is drawn in the middle.
+markup::
+ A string that indicates how the text of the block should be parsed. Set to
+ +"pango"+ to use https://developer.gnome.org/pango/stable/PangoMarkupFormat.html[Pango markup].
+ Set to +"none"+ to not use any markup (default). Pango markup only works
+ if you use a pango font.
