Initial attempt to make use of left and right margins if the terminal supports them (that is, if it advertises itself as a VT420 - probably just xterm). These are the vertical equivalent of the scroll region and allow much faster scrolling of panes that do not take up the full width of the terminal.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

#define tty_use_margin(tty) \
Tidy up the terminal detection and feature code and add named sets of terminal features, each of which are defined in one place and map to a builtin set of terminfo(5) capabilities. Features can be specified based on TERM with a new terminal-features option or with the -T flag when running tmux. tmux will also detect a few common terminals from the DA and DSR responses. This is intended to make it easier to configure tmux's use of terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5) databases or for features which do not yet have a terminfo(5) entry. Instead of having to grok terminfo(5) capability names and what they should be set to in the terminal-overrides option, the user can hopefully just give tmux a feature name and let it do the right thing. The terminal-overrides option remains both for backwards compatibility and to allow tweaks of individual capabilities. tmux already did much of this already, this makes it tidier and simpler to configure.

When the data we have buffered to write to a terminal grows beyond a reasonable amount (currently width * height * 8 bytes), discard all output to the terminal and start trying to redraw periodically instead. Continue with this until the amount of data we are trying to write falls to a low level again. This helps to prevent tmux sitting on a huge buffer of data when there are processes with fast output running inside tmux but the outside terminal is slow. A new client_discarded format holds the amount of data that has been discarded due to this mechanism. The three variables (when to start this, when to stop, and how often to redraw) are basically "works for me" at the moment, this is going in to see how it goes and if it causes problems for anyone else.

Have the client pass its stdin fd to the server when identifying itself and have the server use that rather than reopening the tty. If the fd isn't given, use the old behaviour (so no need for a version change). This allows tmux to be used as the shell, so also change so that when working out the command to execute if default-command is empty (the default), tmux will try not execute itself.

Fix problems with window sizing seen by Raghavendra D Prabhu when starting tmux from .xinitrc. One of the very few things the server relies on the client for now is to pass through a message on SIGWINCH, but there is a condition where potentially a SIGWINCH may be lost during the transition from unattached (main.c) to attached (client.c). So trigger a size change immediately after the client installs its SIGWINCH handler. Also, when the terminal is resized, reset the scroll region and cursor position. Previously, we were clearing our saved idea of these, but in fact some terminals do not reset them on resize, so this caused problems during redraw. While here make a resize to the same size not cause a redraw and rename the tmux.out output log file to include the tmux PID.

It is not OK to ignore SIGWINCH if SIOCGWINSZ reports the size has unchanged, because it may have changed and changed back in the time between us getting the signal and calling ioctl(). Always redraw when we see SIGWINCH.

This currently assumes that keys will be atomic (ie that if eg F1 is pressed the entire sequence is present in the buffer).

When the data we have buffered to write to a terminal grows beyond a reasonable amount (currently width * height * 8 bytes), discard all output to the terminal and start trying to redraw periodically instead. Continue with this until the amount of data we are trying to write falls to a low level again. This helps to prevent tmux sitting on a huge buffer of data when there are processes with fast output running inside tmux but the outside terminal is slow. A new client_discarded format holds the amount of data that has been discarded due to this mechanism. The three variables (when to start this, when to stop, and how often to redraw) are basically "works for me" at the moment, this is going in to see how it goes and if it causes problems for anyone else.

Tidy up the terminal detection and feature code and add named sets of terminal features, each of which are defined in one place and map to a builtin set of terminfo(5) capabilities. Features can be specified based on TERM with a new terminal-features option or with the -T flag when running tmux. tmux will also detect a few common terminals from the DA and DSR responses. This is intended to make it easier to configure tmux's use of terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5) databases or for features which do not yet have a terminfo(5) entry. Instead of having to grok terminfo(5) capability names and what they should be set to in the terminal-overrides option, the user can hopefully just give tmux a feature name and let it do the right thing. The terminal-overrides option remains both for backwards compatibility and to allow tweaks of individual capabilities. tmux already did much of this already, this makes it tidier and simpler to configure.

The default builtin bindings for the mouse are: bind -n MouseDown1Pane select-pane -t=; send-keys -M bind -n MouseDown1Status select-window -t= bind -n MouseDrag1Pane copy-mode -M bind -n MouseDrag1Border resize-pane -M To get the effect of turning mode-mouse off, do: unbind -n MouseDrag1Pane unbind -temacs-copy MouseDrag1Pane The old mouse options are now gone, set-option -q may be used to suppress warnings if mixing configuration files.

When the data we have buffered to write to a terminal grows beyond a reasonable amount (currently width * height * 8 bytes), discard all output to the terminal and start trying to redraw periodically instead. Continue with this until the amount of data we are trying to write falls to a low level again. This helps to prevent tmux sitting on a huge buffer of data when there are processes with fast output running inside tmux but the outside terminal is slow. A new client_discarded format holds the amount of data that has been discarded due to this mechanism. The three variables (when to start this, when to stop, and how often to redraw) are basically "works for me" at the moment, this is going in to see how it goes and if it causes problems for anyone else.

The three variables (when to start this, when to stop, and how often to redraw) are basically "works for me" at the moment, this is going in to see how it goes and if it causes problems for anyone else.

Tidy up the terminal detection and feature code and add named sets of terminal features, each of which are defined in one place and map to a builtin set of terminfo(5) capabilities. Features can be specified based on TERM with a new terminal-features option or with the -T flag when running tmux. tmux will also detect a few common terminals from the DA and DSR responses. This is intended to make it easier to configure tmux's use of terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5) databases or for features which do not yet have a terminfo(5) entry. Instead of having to grok terminfo(5) capability names and what they should be set to in the terminal-overrides option, the user can hopefully just give tmux a feature name and let it do the right thing. The terminal-overrides option remains both for backwards compatibility and to allow tweaks of individual capabilities. tmux already did much of this already, this makes it tidier and simpler to configure.

When drawing lines that have wrapped naturally, don't force a newline but permit them to wrap naturally again. This allows terminals that use this to guess where lines start and end for eg mouse selecting (like xterm) to work correctly.

This was not trivial to get right so bringing it in for wider testing and adn to fix any further glitches in-tree.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Tidy up the terminal detection and feature code and add named sets of terminal features, each of which are defined in one place and map to a builtin set of terminfo(5) capabilities. Features can be specified based on TERM with a new terminal-features option or with the -T flag when running tmux. tmux will also detect a few common terminals from the DA and DSR responses. This is intended to make it easier to configure tmux's use of terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5) databases or for features which do not yet have a terminfo(5) entry. Instead of having to grok terminfo(5) capability names and what they should be set to in the terminal-overrides option, the user can hopefully just give tmux a feature name and let it do the right thing. The terminal-overrides option remains both for backwards compatibility and to allow tweaks of individual capabilities. tmux already did much of this already, this makes it tidier and simpler to configure.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

When drawing lines that have wrapped naturally, don't force a newline but permit them to wrap naturally again. This allows terminals that use this to guess where lines start and end for eg mouse selecting (like xterm) to work correctly. This was another long-standing issue raised by several people over the last while. Thanks to martynas@ for much testing. This was not trivial to get right so bringing it in for wider testing and adn to fix any further glitches in-tree.

The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

This makes various escape sequences (notable EL and ED but also IL, DL, ICH, DCH) create blank cells using the current background colour rather than the default colour. On modern systems BCE doesn't really have many benefits, but most other terminals now support it, some (lazy) applications rely on it, and it is not hard to include now that we have pane background colours anyway. Mostly written by Sean Haugh.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

When drawing lines that have wrapped naturally, don't force a newline but permit them to wrap naturally again. This allows terminals that use this to guess where lines start and end for eg mouse selecting (like xterm) to work correctly.

This was not trivial to get right so bringing it in for wider testing and adn to fix any further glitches in-tree.

Collect sequences of printable ASCII characters and process them together instead of handling them one by one. This is significantly faster. Sequences are terminated when we reach the end of the line, fill the internal buffer, or a different character is seen by the input parser (an escape sequence, or UTF-8). Rather than writing collected sequences out immediately, hold them until it is necessary (another screen modification, or we consume all available data). This means we can discard changes that would have no effect (for example, lines that would just be scrolled off the screen or cleared). This reduces the total amount of data we write out to the terminal - not important for fast terminals, but a big help with slow (like xterm).

Support for windows larger than visible on the attached client. This has been a limitation for a long time. There are two new options, window-size and default-size, and a new command, resize-window. The force-width and force-height options and the session_width and session_height formats have been removed. The new window-size option tells tmux how to work out the size of windows: largest means it picks the size of the largest session, smallest the smallest session (similar to the old behaviour) and manual means that it does not automatically resize windows. The default is currently largest but this may change. aggressive-resize modifies the choice of session for largest and smallest as it did before. If a window is in a session attached to a client that is too small, only part of the window is shown. tmux attempts to keep the cursor visible, so the part of the window displayed is changed as the cursor moves (with a small delay, to try and avoid excess redrawing when applications redraw status lines or similar that are not currently visible). The offset of the visible portion of the window is shown in status-right. Drawing windows which are larger than the client is not as efficient as those which fit, particularly when the cursor moves, so it is recommended to avoid using this on slow machines or networks (set window-size to smallest or manual). The resize-window command can be used to resize a window manually. If it is used, the window-size option is automatically set to manual for the window (undo this with "setw -u window-size"). resize-window works in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has -a and -A flags. -a sets the window to the size of the smallest client (what it would be if window-size was smallest) and -A the largest. For the same behaviour as force-width or force-height, use resize-window -x or -y, and "setw -u window-size" to revert to automatic sizing.. If the global window-size option is set to manual, the default-size option is used for new windows. If -x or -y is used with new-session, that sets the default-size option for the new session. The maximum size of a window is 10000x10000. But expect applications to complain and much higher memory use if making a window excessively big. The minimum size is the size required for the current layout including borders. The refresh-client command can be used to pan around a window, -U -D -L -R moves up, down, left or right and -c returns to automatic cursor tracking. The position is reset when the current window is changed.

Tidy up the terminal detection and feature code and add named sets of terminal features, each of which are defined in one place and map to a builtin set of terminfo(5) capabilities. Features can be specified based on TERM with a new terminal-features option or with the -T flag when running tmux. tmux will also detect a few common terminals from the DA and DSR responses. This is intended to make it easier to configure tmux's use of terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5) databases or for features which do not yet have a terminfo(5) entry. Instead of having to grok terminfo(5) capability names and what they should be set to in the terminal-overrides option, the user can hopefully just give tmux a feature name and let it do the right thing. The terminal-overrides option remains both for backwards compatibility and to allow tweaks of individual capabilities. tmux already did much of this already, this makes it tidier and simpler to configure.

Collect sequences of printable ASCII characters and process them together instead of handling them one by one. This is significantly faster. Sequences are terminated when we reach the end of the line, fill the internal buffer, or a different character is seen by the input parser (an escape sequence, or UTF-8). Rather than writing collected sequences out immediately, hold them until it is necessary (another screen modification, or we consume all available data). This means we can discard changes that would have no effect (for example, lines that would just be scrolled off the screen or cleared). This reduces the total amount of data we write out to the terminal - not important for fast terminals, but a big help with slow (like xterm).

Tidy up the terminal detection and feature code and add named sets of terminal features, each of which are defined in one place and map to a builtin set of terminfo(5) capabilities. Features can be specified based on TERM with a new terminal-features option or with the -T flag when running tmux. tmux will also detect a few common terminals from the DA and DSR responses. This is intended to make it easier to configure tmux's use of terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5) databases or for features which do not yet have a terminfo(5) entry. Instead of having to grok terminfo(5) capability names and what they should be set to in the terminal-overrides option, the user can hopefully just give tmux a feature name and let it do the right thing. The terminal-overrides option remains both for backwards compatibility and to allow tweaks of individual capabilities. tmux already did much of this already, this makes it tidier and simpler to configure.

If default-terminal is set to "screen" or "screen-*", emulate screen's historical (incorrect) behaviour for SGR 3 and send smso (standout). Previously, we would send sitm (italics) if the terminal outside had it and smso otherwise. This was acceptably until recently because xterm's terminfo entry lacked sitm, so most users got smso. People who want italics should set default-terminal to the forthcoming "tmux" entry (and be prepared to deal with it being missing on older hosts). As a side-effect this changes default-terminal to be a server rather than a session option. suggested by and ok naddy

/* Not a 24-bit terminal? Translate to 256-colour palette. */
Tidy up the terminal detection and feature code and add named sets of terminal features, each of which are defined in one place and map to a builtin set of terminfo(5) capabilities. Features can be specified based on TERM with a new terminal-features option or with the -T flag when running tmux. tmux will also detect a few common terminals from the DA and DSR responses. This is intended to make it easier to configure tmux's use of terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5) databases or for features which do not yet have a terminfo(5) entry.

{
Do not hoke into struct window_pane from the tty code and instead set everything up in tty_ctx. Provide a way to initialize the tty_ctx from a callback and use it to let popups draw directly through input_parse in the same way as panes do, rather than forcing a full redraw on every change.

Add support for BCE (background colour erase). This makes various escape sequences (notable EL and ED but also IL, DL, ICH, DCH) create blank cells using the current background colour rather than the default colour.
