* Add and use lenient_strcat and lenient_strncat functions
* Rename `concatenate_child_titles` function as that's no longer what it
does
* Rename `container_notify_child_title_changed` because we only need to
notify that the tree structure has changed, not titles
* Don't notify parents when a child changes its title
* Update ancestor titles when changing a container's layout
* Eg. create nested tabs and change the inner container to stacking
* No need to store tree presentation in both container->name and
formatted_title
Swayidle handles idle events and allows
for dpms and lockscreen handling. It also
handles systemd sleep events, and can
raise a lockscreen on sleep
Fixes#541
The criteria struct now uses properties for each token type rather than
the list_t list of tokens. The reason for this is that different token
types have different data types: pcre, string and number to name a few.
This solution should be more flexible moving forward. A bonus of this is
that criteria is now easier to understand when looking at the struct
definition.
The criteria parser has been rewritten because the previous one didn't
support valueless pairs (eg. [class="foo" floating]).
Criteria now has types. Types at the moment are CT_COMMAND,
CT_ASSIGN_WORKSPACE and CT_ASSIGN_OUTPUT. i3 uses types as well.
Previously the assign command was creating a criteria with 'move to
workspace <name>' as its command, but this caused the window to appear
briefly on the focused workspace before being moved to the assigned
workspace. It now creates the view directly in the assigned workspace.
Each view will only execute a given criteria once. This is achieved by
storing a list of executed criteria in the view. This is the same
strategy used by i3.
Escaping now works properly. Previously you could do things like
[class="Fire\"fox"] and the stored value would be 'Fire\"fox', but it
should be (and now is) 'Fire"fox'.
The public functions in criteria.c are now all prefixed with criteria_.
Xwayland views now listen to the set_title, set_class and
set_window_type events and criteria will be run when these happen. XDG
shell has none of these events so it continues to update the title in
handle_commit.
Each view type's get_prop function has been split into get_string_prop
and get_int_prop because some properties like the X11 window ID and
window type are numeric.
The following new criteria tokens are now supported:
* id (X11 window ID)
* instance
* tiling
* workspace
This implements the title_format command, with a new placeholder %shell
which gets substituted with the view type (xwayland, xdg_shell_v6 or
wl_shell).
Example config:
for_window [title=".*"] title_format %title (class=%class instance=%instance shell=%shell)
