If the statusline generator (i.e. i3status) specifies click_events:true
in the protocol header, i3bar will write a JSON array on it's stdin
notifying it if the user clicks on a block.
The exact protocol is documented in docs/i3bar-protocol.
With this change, min_width can either be an integer (as usual), or a
string. In the latter case, the width of the text given by min_width
determines the minimum width of the block. This way one does not have to
figure out a minimum width by trial and error, only to do it again every
time the font is changed.
This patch adds the following features:
1) Configure a color of the separator via config. It is done like
bar {
colors {
separator #000000
}
}
2) A block can have an integer entry "separator_block_width" which
sets the width of the gap which would follow after the current block.
3) A block can have a boolean entry "separator" and if it is set
to false, then the drawing of the separating line would be disabled.
