The cause is that the command criteria are matching a window in the
scratchpad. In that case, the assertion in get_output_for_con() fails.
That happens because there is no `Output` for the `Con` output of a
scratchpad window.
I've decided to *not* remove the offending assertion but rather rely on
the caller not using the function with internal containers. My reasoning
is:
1. If get_output_for_con can return NULL then the caller will either
segfault (which is worse) or needs to check the return for NULL.
2. The case where the return can be NULL is already known, it happens
for internal containers.
3. Therefore, the caller should already prevent the situation with a
call to con_is_internal(). Thus, the `assert`ion can remain.
There is also the potential fix of con_get_workspace returning some
arbitrary output (e.g. first in the list or currently focused one)
instead of NULL. This can lead to more tricky to catch bugs.
Currently simply returns output->name, but this will make it easier to
change how output names are stored in the following commits.
Also replace reading output->name with invocations of
output_primary_name. Code which writes output->name is unchanged. Done
using a mostly mechanical replacement of output->name to
output_primary_name(output).
Including config.h is necessary to get e.g. the _GNU_SOURCE define and
any other definitions that autoconf declares. Hence, config.h needs to
be included as the first header in each file.
This is done either via:
1. Including "common.h" (i3bar)
2. Including "libi3.h"
3. Including "all.h" (i3)
4. Including <config.h> directly
Also remove now-unused I3__FILE__, add copyright/license statement
where missing and switch include/all.h to #pragma once.
This commit also reworks the way focusing sticky windows is prevented by not focusing them temporarily at all, but preventing the focus in the first place.
