v0.8.0

tmux-control 0.8.0

Names

• The mode line names the host and tmux window, such as "dev › build", in
  place of the buffer name, and the terminal's mode reads "tmux". Set
  tmux-control-mode-line-window-name to nil to keep the buffer name.
• Buffers are named "*tmux HOST:SESSION*", "local" for the local server,
  with the socket in parentheses when it isn't the default, and a window's,
  pane's or scrollback's suffix after that, such as "*tmux dev:work @2*".
  Update anything in your configuration that matches the old names.

Keys and links

• Shift+Return reaches the program as tmux's own S-Enter on tmux 3.5 and
  later, so it starts a new line in Claude Code's prompt rather than sending
  it. So does Option+Return, as M-Enter, in a GUI frame's semi-char mode.
  Older servers get the bytes as before.
• A lone ESC stays whole: the M-RET override binding is gone.
• C-c C-u opens a URL shown on the screen. Links that programs mark with
  OSC 8 open with a click or C-c C-u in the live view, and with a click or
  RET in scrollback.
• C-c C-o moves to the next pane's window in a tiled view.

Split windows

• A split window keeps its tabs: the header line sits over the top-left pane,
  and tmux lays the panes out one row shorter to make room. Each pane keeps
  the mode line other windows have, naming its host, window and pane.
• When a split closes, the view goes back to one pane, with its tabs.
• A new tiled view keeps you on the pane you were looking at, tmux's active
  one, so C-c | focuses the new pane, as tmux does.
• Switching sessions replaces all of a split session's panes, and returning
  to it splits it again.

What you see

• Panes render as tmux does where Eat's emulation departs from it, checked
  against tmux by a differential test (make test-vt-oracle).
  tmux-control-correct-emulation turns the corrections off.
• A normal screen repaints from tmux after any change in size, so it stays on
  tmux's screen as a pane gets shorter, taller, narrower or wider, and long
  lines wrap where tmux wraps them. A full-screen program repaints itself.
• A repainted screen starts on a line of its own, which fixes a garbled first
  row after returning to a split session.
• No-break spaces show as spaces.

Speed

• Keystrokes are answered sooner, panes that keep scrolling stay fast, and a
  settled window is left alone when output arrives.
• Idle collection (tmux-control-idle-gc-mode) checks from idle timers
  rather than 20 times a second, and terminal buffers keep no undo.
• A window showing a window buffer resizes tmux when it changes size.

Diagnostics

• tmux-control-pause-log-mode notes each time Emacs stops responding for
  tmux-control-pause-log-threshold seconds, with the command, tmux output
  or timer that took most of it, or else that redisplay or another program's
  output most likely did, and the time spent collecting garbage.
  tmux-control-diagnostics lists the latest notes.

For packages

• tmux-control-switch-session-functions lets a package show a session its
  own way when you switch to it from a view, as Roost does to open the task.
  tmux ending a connection is said once.
