When headers were installed in more sofisticated places (but package
config knows it right), it revealed missing paths in CMake
configuration. Lets fix it.
In the i3bar protocol the value of the markup field is a string: "pango"
or "none" rather than a bool. This patch makes swaybar compatible with
that.
http://i3wm.org/docs/i3bar-protocol.html
Calling `exit` in sway_terminate prevents sway from correctly shutting
down (freeing data, cleanly terminating the ipc server, etc.).
A better way is to exit straight away if the failure occurs before
`wlc_run` and use sway_abort as usual if it occur when wlc is running.
Makes `ipc_recv_response` return a struct with size, type and payload
rather than just the payload string.
This is useful if the type has to be checked on the client.
This extends the i3bar protocol implementation with the following
features from @Airblade/i3:
* background
* border
* border_top, border_bottom, border_left, border_right
A block will now be rendered like this:
```
(border_left + margin) + width + (margin + border_right) + sep
```
Where `border_left/border_right` and their related margin is only drawn
if the `border` is specified and the border has a width > 0 (default is
1).
`border_top` and `border_bottom` does not affect the height of the bar
(no margin is added), thus it will be drawn behind the text if it is too
big. The user should specify a bar height if more space between
top/bottom borders are required.
This should fix the random json related crashes in swaybar.
The crashes occured because the same socket was used for listening on
workspace events and requesting workspace info, resulting in a
unreliable message queue on the socket.
The solution is to use one socket for the events and one socket for
reliably requesting workspace/output info.
