Infrastructure and commands to manage the environment for processes started
within tmux.
There is a global environment, copied from the external environment when the
server is started and each session has an (initially empty) session
environment which overrides it.
New commands set-environment and show-environment manipulate or display the
environments.
A new session option, update-environment, is a space-separated list of
variables which are updated from the external environment into the session
environment every time a new session is created - the default is DISPLAY.
Each window now has a tree of layout cells associated with it. In this tree,
each node is either a horizontal or vertical cell containing a list of other
cells running from left-to-right or top-to-bottom, or a leaf cell which is
associated with a pane.
The major functional changes are:
- panes may now be split arbitrarily both horizontally (splitw -h, C-b %) and
vertically (splitw -v, C-b ");
- panes may be resized both horizontally and vertically (resizep -L/-R/-U/-D,
bound to C-b left/right/up/down and C-b M-left/right/up/down);
- layouts are now applied and then may be modified by resizing or splitting
panes, rather than being fixed and reapplied when the window is resized or
panes are added;
- manual-vertical layout is no longer necessary, and active-only layout is gone
(but may return in future);
- the main-pane layouts now reduce the size of the main pane to fit all panes
if possible.
Thanks to all who tested.
status line (bound to "i" by default).
- Add support for including the window index, pane index, and window name
in status-left, or status-right.
- Bump protocol version.
from any sessions. In fact the implementation only affected the current
session, making it the same as unlink-window but destroying the window if it
was linked into only one session (unlinkw gives an error). Change the behaviour
to match what it documented and was originally intended.
decision for whether or not a pane should be drawn out of the layout code and
into the redraw code.
This is needed for the new layout design, getting it in now to make that easier
to work on.
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.
highlight the status line if it matches.
- To make this possible, the function cmd_find_window_search from
cmd-find-window.c had to be moved to window.c and renamed window_pane_search.
- While there use three new functions in server.c to check for bell, activity,
and content, to avoid too much nesting.
- change the one layout function into two _refresh and _resize
- create layout-manual.c for manual layout code
- move the fit panes/update panes code from window.c to the new file as it is only used by manual layout now
- move the resize pane code into layout-manual.c as well
- get rid of the direct calls to fit/update and make them go through layout
- rename a couple of variables
This is mainly as a first step before reworking the manual layout code to see if anything breaks.
script which must be run before building.
Still two makefiles but they are a hell of a lot simpler.
HAVE_* also will make it easier to move to $buildsystem if necessary later.
issues - particularly, don't mix with manual pane resizing and be careful when
viewing from multiple clients; generally cycling the layout a few times will
fix most problems. Getting this in for testing while I think about how to deal
with manual mode.
Split window as normal and cycle the layouts with C-b space. Some of the
layouts will work better when swap-pane comes along.
by reading argv[0] from the process group leader of the group that owns the tty
(tcgetpgrp()). This can't be done portably so some OS-dependent code is
introduced (ugh); OpenBSD, FreeBSD and Linux are supported at the moment.
A new window flag, automatic-rename, is available: if this is set to off, the
window name is not changed. Specifying a name with the new-window, new-session
or rename-window commands will automatically set this flag to off for the
window in question. To disable it entirely set the option to off globally (setw
-g automatic-rename off).
an arbitrary width and height (0 for the default unlimited). This is neat for
emacs which doesn't have a sensible way to force hard wrapping at 80
columns. Also, don't try to be clever and use clr_eol when redrawing the
whole screen, it causes trouble since the redraw functions are used to draw
the blank areas too.
