This patch adds the ability to customize the separator that is placed
between modules.
Specifically this patch:
* adds the "separator" general directive
* moves the definition of the default separator for the different
output formats (excluding color formatting) to src/i3status.c
* updates the SEC_CLOSE_MAP macro to disable the separator for the
i3bar output format if the separator directive dictates so
* changes print_seperator() in src/output.c to take a separator
parameter in order to disable the output of the separator if
the separator is empty and to use the provided separator
otherwise
* updates the manpage to explain the new directive
This patch inlines the creation of the thermal zone string in order
to force computation on each invocation. This is necessary to be able
to read the values of several temperature sensors.
If the volume is muted, the volume level would simply be displayed as zero and the color changed to color_degraded.
This patch lets the user define a custom format string for when the volume is muted.
The default value is "♪: 0%" ("♪: %volume" being the usual format).
i3 starts processes using /bin/sh now, not $SHELL. This increases the
likelihood with which we are started by dash, which tends to leave its
processes in the hierarchy, e.g.:
michael 1524 i3bar --bar_id=bar-0 --socket=/run/user/1000/i3/ipc-s
michael 1525 \_ /bin/sh -c i3status
michael 1526 \_ i3status
This case is now handled correctly — when the parent is “sh”, the parent
of sh will be used instead.
If we don't do this, the output of i3status will remain on the terminal,
which is really ugly if the statusline becomes shorter after a while
(for example a connection get's lost), because there will be garbage.
On GNU/Hurd, THERMAL_ZONE is undefined. This makes compilation fail as
outwalk is declared inside of #ifdef THERMAL_ZONE, but it's used outside
of it (by OUTPUT_FULL_TEXT).
This moves the declaration outside the #ifdef to allow for successful
compilation on Hurd again.
