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.
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.
If the first line of the input starts with {"version":, then the input is
considered to be JSON, otherwise it is interpreted as plain text.
Only the "full_text" and "color" parts of a block are currently understood by
i3bar.
Fixes the case where multiple lines are read in a single read syscall
(it could be better optimized in the future). Also fixes a memory
corruption issue when rec == 0.
