359285928b Support "alternate screen" mode (terminfo smcup/rmcup) typically used by full 
screen interactive programs to preserve the screen contents. When activated, it
saves a copy of the visible grid and disables scrolling into and resizing out
of the history; when deactivated the visible data is restored and the history
reenabled.

9e49ec6cd3 Creating a key binding which replaces itself (such as "bind x bind x lsw") 
frees the command list bound to the key while it is still being executed,
leading to a use after free. To prevent this, create a dead keys list and defer
freeing replaced or removed key bindings until the main loop when the key
binding will have finished executing.

Found by Johan Friis when creating a key binding to reload his configuration
file.

22d51ec1ea Add a "back to indentation" key in copy mode to move the cursor to the first 
non-whitespace character. ^ with vi and M-m with emacs key bindings. Another
from Kalle Olavi Niemitalo, thanks.

user-specified one.

bd098c273b Limit the history to hlimit not hlimit - 1. This makes a history-limit setting 
of 0 work as expected.

e415ead361 Add -r to the synopsis of the paste-buffer command, prompted by jmc. 2009-07-11 20:04:19 +00:00
Nicholas Marriott
2f7198246e When pasting, translate \n into \r. This matches xterm and putty's behaviour, 
and makes emacs happy when pasting into some modes. A new -r (raw) flag to
paste-buffer pastes without the translation.

From Kalle Olavi Niemitalo, thanks!

289320a9b1 Copy was using the real line length which after resize can be larger than the 
screen width. When built with -DDEBUG, this made the grid bounds checking code
kill the server. Restrict copying to the actual width.

From Kalle Olavi Niemitalo, thanks.

4a6d62e401 Don't send initialisation strings is1/2/3 (barely anything else does) and move 
smcup to the first and rmcup to the last sequences output to the terminal. This
allows tmux to use the alternate screen (smcup/rmcup) when available.

daa1faa905 Add a default-terminal option to set the starting value of $TERM in new 
windows.

This is "screen" by default and must be either that or something closely
related. This does makes it easier to customise it if necessary.

58361eb965 When the terminal size is reduced horizontally, don't truncate lines to the new 
width, so that if the same lines are later increased in size the content
reappears.

5f2f07ed8a Cursor up and down should be limited by the scroll region (cuu should stop at 
the scroll region top if starting from below it and cud stop at the bottom if
starting from above). Fixes another vttest test.

81181bfb72 New command, if-shell (alias if). Executes the tmux command in the second 
argument if the shell command in the first succeeds, for example:

       if "[ -e ~/.tmux.conf.alt ]" "source .tmux.conf.alt"

Written by Tiago Cunha, many thanks.

643c219d18 Tidy by removing unused argument from grid_view_{insert,delete}_line_region 
functions (currently don't fully work, this is to make fix easier).

Nicholas Marriott
084d07f4eb Just appending -l to $SHELL to create a login shell is wrong: -l is not POSIX, 
and some people may use shells which do not support it. Instead, make an empty
default-command option mean a login shell, and fork it with a - in argv[0]
which is the method used by login(1).

Also fix the automatic-rename code to handle this correctly and to strip a
leading - if present.

b4efd1ca89 Don't let ambiguous commands override an exact alias match: eg if commands 
"abc-1", "abc-2", "abc-3" exist and "abc-3" has the alias "abc", "tmux abc"
should execute abc-3, not complain about the command being ambiguous.

Not a problem at the moment but will be soon.

923ccfa2e8 Rename the global options variables to be shorter and to make session options 
clear. No functional change, getting this out of the way to make later options
changes easier.

afterwards, otherwise it hangs.

e538d4adae The fix for default-path (use target session options instead of global options) 
is required here as well, doh.

eb424cf63d Minor fix: look for default-path in the options for the specified session first 
rather than just the global options. From Brandon Mercer, thanks.

69e150b7e3 Add a section summarising how options work, make the distinction between window 
and session options clearer, and fix the incorrect synopses and descriptions of
show-options and show-window-options.

fe5edad1fc Fix two copy/paste bugs: forbid zero-length buffers to prevent a fatal error 
when trying to paste them, found by me, and miscalculation of the start/end
causing random fatal errors when copying in copy-mode, reported by sthen.

4c5c125173 When unlocking the server, don't try to clear the prompt on clients without a 
prompt (such as the one issuing the unlock request).

This caused the server to die if the wrong password was entered when unlocking
from the command line with -U (nasty).

68e06fb6b7 Fix two errors with character/line insertion and deletion: the maximum number 
of characters which may be inserted or deleted is the screen width, not one
less (and similarly for lines and height); and if characters or lines are
deleted by moving the ones that follow, the space at the end needs to be
cleared.

This appears to solve long-standing redraw issues most visible when using the
force-width option then scrolling in view(1) or unwrapping lines in emacs.

003e8e65f7 Don't try to page up with scroll-mode -u or copy-mode -u unless the mode was 
successfully changed - if already in a different mode, it would corrupt the
mode data.

710393e388 Use gmtime_r so the current time isn't overwritten, the minute comparison works 
and the clock is actually updated. It was already used for lock-server but not
here.

1ec736a3dc Status line fixes: don't truncate status-right now the length calculation is 
done for UTF-8, limit to the maximum length correctly when printing, and always
print a space even if the left string is longer than the width available.
