additional payload (to reduce problems with lifetime of objects) and are
delivered to one or more event sinks. This is more powerful and reduces the
complex dependencies between control mode and hooks. Events are now used for
hooks, control mode notifications and for monitors (set-hook -B).
wait-for can now wait for an event to fire (-E flag, with -F to for filter),
with -v to print the payload, as well as listing (-l) waiting clients on an
event and forcing one to wake (-w).
A few additional hooks are also now available (pane-created, pane-resized, etc)
and some of the existing ones have additional format variables available.
replaces the previous "modal" behaviour where the pane would be resized,
which tended to make a mess. Instead, the scrollbar appears when
scrolling or when hovered over with the mouse and disappears a
(configurable) short period later. From Michael Grant.
are now wrapped up in prompt*.c and do not depend on a client. These
functions are used to provide the original client prompt but also to
allow panes to have their own prompts, which works much much better for
floating panes. The mode prompts for both the tree modes and copy mode
are switched over to be per pane.
There are some visible changes (some of these may be changed if they
don't seem to be working well):
- Prompts in modes now appear in the bottom line, covering whatever
content was there.
- command-prompt has a -P flag to open a pane prompt.
- Because they cover the content, the default style for prompts in modes
now does not fill the entire line; the main command prompt stays the
same.
- The old completion menu has gone, and completions are now shown after
the text. Builtin aliases are no longer completed.
- Clicking the mouse on the prompt now moves the cursor or selects a
completion.
is generated and cached in the client: it holds positions and sizes of
panes, borders and so on. The scene is invalidated when a pane is moved
or resized or relevant option is changed. This scene is then drawn to
the client as needed and text and colours are filled in. With Michael
Grant.
- Fix the active pane colour when only two panes and scrollbars enabled.
- Clip left and right scrollbars the same for floating panes.
- Do not subtract scrollbar width twice when working out width of status
line.
- Check if a character is inside a visible range correctly (do not
include the next position outside the range).
