- actually add a buildrequires for pkgconfig so we can use that for
- allow building on older distros which do not have
  pkgconfig(ncurses) yet by requiring ncurses-devel there.

  the macro
- expand tmpfiles_create macro as it isnt defined on sle12 e.g.
* Thu May 07 2015
- update to version 2.0
  - Incompatible changes:
  - The choose-list command has been removed.
  - 'terminal-overrides' is now a server option, not a session
  - 'message-limit' is now a server option, not a session option.
  - 'monitor-content' option has been removed.
  - 'pane_start_path' option has been removed.
  - The "info" mechanism which used to (for some commands)
    provide feedback has been removed, and like other commands,
    they now produce nothing on success.
  - Normal changes:
  - tmux can now write an entry to utmp if the library 'utempter'
    is present at compile time.
  - set-buffer learned append mode (-a), and a corresponding
    'append-selection' command has been added to copy-mode.
  - choose-mode now has the following commands which can be
  - start-of-list
  - end-of-list
  - top-line
  - bottom-line
  - choose-buffer now understands UTF-8.
  - Pane navigation has changed:
  - The old way of always using the top or left if the choice
    is ambiguous.
  - The new way of remembering the last used pane is annoying
    if the layout is balanced and the leftmost is obvious to
    the user (because clearly if we go right from the
    top-left in a tiled set of four we want to end up in
    top-right, even if we were last using the bottom-right).
    So instead, use a combination of both: if there is only
    one possible pane alongside the current pane, move to it,
    otherwise choose the most recently used of the choice.
  - 'set-buffer' can now be told to give names to buffers.
  - The 'new-session', 'new-window', 'split-window', and
    'respawn-pane' commands now understand multiple arguments and
    handle quoting problems correctly.
  - 'capture-pane' understands '-S-' to mean the start of the
    pane, and '-E-' to mean the end of the pane.
  - Support for function keys beyond F12 has changed.  The
    following explains:
  - F13-F24 are S-F1 to S-F12
  - F25-F36 are C-F1 to C-F12
  - F37-F48 are C-S-F1 to C-S-F12
  - F49-F60 are M-F1 to M-F12
  - F61-F63 are M-S-F1 to M-S-F3
    Therefore, F13 becomes a binding of S-F1, etc.
  - Support using pane id as part of session or window specifier
    (so % means session-of-%1 or window-of-%1) and window id as
    part of session
    (so @1 means session-of-@1).
  - 'copy-pipe' command now understands formats via -F
  - 'if-shell'  command now understands formats via -F
  - 'split-window' and 'join-window' understand -b to create the
    pane to the left or above the target pane.
- drop obsolete tmux-fix-malloc-check-abort.patch
* Fri Nov 14 2014
- tmux-socket-path.patch: Just like screen, create socket
  directory with tmpfiles.d functionality in /run/tmux
  and not in /tmp. This patch only alters the default
  directory that can be still overrriden by setting
  TMUX_TMPDIR or TMPDIR environment variable. This add some
  robustness against accidental deletion via
  systemd-tmpfiles-clean, tmpwatch, or similar.
* Thu Nov 13 2014
- Add full download url for the tarball fetching/verification
* Sun Nov 02 2014
- add tmux-fix-malloc-check-abort.patch in order to fix glibc
  aborting on openSUSE Factory due toits MALLOC_CHECK_ settings
  (, bnc#869950)
* Sun Feb 23 2014
- update to version 1.9a
  - Fix crash due to uninitialized lastwp member of layout_cell
  - Fix -fg/-bg/-style with 256 colour terminals.
* Thu Feb 20 2014
- update to version 1.9
  - NOTE: This release has bumped the tmux protocol version. It is
    therefore advised that the prior tmux server is restarted when
    this version of tmux is installed, to avoid protocol mismatch
    errors for newer clients trying to talk to an older running
    tmux server.
  - 88 colour support has been removed.
  - 'default-path' has been removed. The new-window command accepts
    '-c' to cater for this. The previous value of "." can be
    replaced with: 'neww -c $PWD', the previous value of '' which
    meant current path of the pane can be specified as: 'neww -c
  - The single format specifiers: #A -> #Z (where defined) have
    been deprecated and replaced with longer-named equivalents, as
    listed in the FORMATS section of the tmux manpage.
  - The various foo-{fg,bg,attr} commands have been deprecated and
    replaced with equivalent foo-style option instead. Currently
    this is still backwards-compatible, but will be removed over
  - A new environment variable TMUX_TMPDIR is now honoured,
    allowing the socket directory to be set outside of TMPDIR
    (/tmp/ if not set).
  - If -s not given to swap-pane the current pane is assumed.
  - A #{pane_syncronized} format specifier has been added to be a
    conditional format if a pane is in a syncronised mode (c.f.
  - Tmux now runs under Cygwin natively.
  - Formats can now be nested within each other and expanded
  - Added 'automatic-rename-format' option to allow the automatic
    rename mechanism to use something other than the default of
  - new-session learnt '-c' to specify the starting directory for
    that session and all subsequent windows therein.
  - The session name is now shown in the message printed to the
    terminal when a session is detached.
  - Lots more format specifiers have been added.
  - Server race conditions have been fixed; in particular commands
    are not run until after the configuration file is read
  - Case insensitive searching in tmux's copy-mode is now possible.
  - attach-session and switch-client learnt the '-t' option to
    accept a window and/or a pane to use.
  - Copy-mode is only exited if no selection is in progress.
  - Paste key in copy-mode is now possible to enter text from the
  - status-interval set to '0' now works as intended.
  - tmux now supports 256 colours running under fbterm.
  - Many bug fixes!

  - resize-pane learnt '-x' and '-y' for absolute pane sizing
  - config file loading now reports errors from all files which are
    loaded via the 'source-file' command
  - 'copy-pipe' mode command to copy selection and pipe the

  - reject $SHELL if it is not a full path
  - add -S option to refresh-client to redraw status line
  - add an else clause for if-shell

  - change the way the working directory for new processes is
    discovered; if default-path isn't empty, it is used; otherwise,
    if a new window is created from the command-line, the working
    directory of the client is used; if not, platform specific code
    is used to retrieve the current working directory of the
    process in the active pane; if that fails, the directory where
    the session was created is used, instead
  - do not change the current pane if both
    mouse-select-{pane,window} are enabled
  - add \033[s and \033[u to save and restore cursor position

    configuring colours
  - drop the ability to have a list of keys in the prefix in favour
    of two separate options, prefix and prefix2

- Add correct systemd requires (boo#976922)
* Tue Apr 12 2016
- Update to 2.2
  + Incompatible changes:
  * The format strings which referenced time have been removed.  Instead:
    [#]{t:window_activity} can be used.
  * Support for TMPDIR has been removed.  Use TMUX_TMPDIR instead.
  * UTF8 detection how happens automatically if the client supports it, hence
    the mouse-utf8, utf8 options has been removed.
  * The mouse_utf8_flag format string has been removed.
  * The -I option to show-messages has been removed.  See #{t:start_time}
    format option instead.
  + Other changes:
  * Panes are unzoomed with selectp -LRUD
  * New formats added:
    [#]{=10:...} -- limit to N characters (from the start)
    [#]{=-10:...} -- limit to N characters (from the end)
    [#]{t:...} -- used to format time-based formats
    [#]{b:...} -- used to ascertain basename from string
    [#]{d:...} -- used to ascertain dirname from string
    [#]{s:...} -- used to perform substitutions on a string

- Incompatible Changes:
  * Mouse-mode has been rewritten.  There's now no longer options for:
  - mouse-resize-pane
  - mouse-select-pane
  - mouse-select-window
  - mode-mouse
  Instead there is just one option:  'mouse' which turns on mouse support
  * 'default-terminal' is now a session option.  Furthermore, if this is set
  to 'screen-*' then emulate what screen does.  If italics are wanted, this
  can be set to 'tmux' but this is still new and not necessarily supported
  on all platforms with older ncurses installs.
  * The c0-* options for rate-limiting have been removed.  Instead, a backoff
  approach is used.

  * 'select-layout' understands '-o' to undo the last layout change.
  * The environment is updated when switching sessions as well as attaching.
  * 'select-pane' now understands '-M' for marking a pane.  This marked pane
  can then be used with commands which understand src-pane specifiers
  * If a session/window target is prefixed with '=' then only an exact match
  is considered.
  * 'move-window' understands '-a'.
  * 'update-environment' understands '-E' when attach-session is used on an
  already attached client.
  * 'show-environment' understands '-s' to output Bourne-compatible commands.
  * New option: 'history-file' to save/restore command prompt history.
  * Copy mode is exited if the history is cleared whilst in copy-mode.

  + Incompatible Changes
  * Key tables have undergone major changes. Mode key tables are no longer
  separate from the main key tables. All mode key tables have been removed,
  together with the -t flag to bind-key and unbind-key.
  The emacs-edit, vi-edit, emacs-choose and vi-choose tables have been replaced
  by fixed key bindings in the command prompt and choose modes. The mode-keys
  and status-keys options remain.
  The emacs-copy and vi-copy tables have been replaced by the copy-mode and
  copy-mode-vi tables. Commands are sent using the -X and -N flags to
  send-keys. So the following:
  bind -temacs-copy C-Up scroll-up
  bind -temacs-copy -R5 WheelUpPane scroll-up
  bind -Tcopy-mode C-Up send -X scroll-up
  bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up
  This changes allows the full command parser (including command sequences) and
  command set to be used - for example, the normal command prompt with editing
  and history is now used for searching, jumping, and so on instead of a custom
  one. The default C-r binding is now:
  bind -Tcopy-mode C-r command-prompt -p'search up' "send -X search-backward '%%'"
  There are also some new commmands available with send -X, such as
  * set-remain-on-exit has gone -- can be achieved with hooks instead.
  * Hooks: before hooks have been removed and only a selection of commands now
  have after hooks (they are no longer automatic). Additional hooks have been
  * The xterm-keys option now defaults to on.
  + Normal Changes
  * Support for mouse double and triple clicks.
  * BCE (Background Colour Erase) is now supported.
  * All occurrences of a search string in copy mode are now highlighted;
  additionally, the number of search results is displayed. The highlighting
  updates interactively with the default emacs key bindings (incremental
  * source-file now understands glob patterns.
  * Formats now have simple comparisons:
  * There are the following new formats:
  - #{version} -- the tmux server version;
  - #{client_termtype} -- the terminal type of the client;
  - #{client_name} -- the name of a client;
  - #{client_written} -- the number of bytes written to the client.
  * The configuration file now accepts %if/%endif conditional blocks which are
  processed when it is parsed; the argument is a format string (useful with the
  new format comparison options).
  * detach-client now has -E to execute a command replacing the client instead of
  * Add support for custom command aliases, this is an array option which
  contains items of the form "alias=command". This is consulted when an
  unknown command is parsed.
  * break-pane now has -n to specify the new window name.
  * OSC 52 support has been added for programs inside tmux to set a tmux buffer.
  * The mouse "all event" mode (1003) is now supported.
  * Palette setting is now possible (OSC 4 and 104).
  * Strikethrough support (a recent terminfo is required).
  * Grouped sessions can now be named (new -t).
  * terminal-overrides and update-environment are now array options (the previous
  set -ag syntax should work without change).
  * There have been substantial performance improvements.
Version: 2.6-15.1
* Tue Oct 17 2017
- update to 2.6
  * Add select-pane -T to set pane title.
  * Fix memory leak when lines with BCE are removed from history.
  * Fix (again) the "prefer unattached" behaviour of attach-session.
  * Reorder how keys are checked to allow keys to be specified that have a
  leading escape. GitHub issue 1048.
  * Support REP escape sequence (\033[b).
  * Run alert hooks based on options rather than always, and allow further bells
  even if there is an existing bell.
  * Add -d flag to display-panes to override display-panes-time.
  * Add selection_present format when in copy mode (allows key bindings that do
  something different if there is a selection).
  * Add pane_at_left, pane_at_right, pane_at_top and pane_at_bottom formats.
  * Make bell, activity and silence alerting more consistent by: removing the
  bell-on-alert option; adding activity-action and silence-action options with
  the same possible values as the existing bell-action; adding a "both" value
  for the visual-bell, visual-activity and visual-silence options to trigger
  both a bell and a message.
  * Add a pane_pipe format to show if pipe-pane is active.
  * Block signals between forking and resetting signal handlers so that the
  libevent signal handler doesn't get called in the child and incorrectly write
  into the signal pipe that it still shares with the parent. GitHub issue 1001.
  * Allow punctuation in pane_current_command.
  * Add -c for respawn-pane and respawn-window.
  * Wait for any remaining data to flush when a pane is closed while pipe-pane is
  in use.
  * Fix working out current client with no target. GitHub issue 995.
  * Try to fallback to C.UTF-8 as well as en_US.UTF-8 when looking for a UTF-8
  * Add user-keys option for user-defined key escape sequences (mapped to User0
  to User999 keys).
  * Add pane-set-clipboard hook.
  * FAQ file has moved out of repository to online.
  * Fix problem with high CPU usage when a client dies unexpectedly. GitHub issue
  * Do a dance on OS X 10.10 and above to return tmux to the user namespace,
  allowing access to the clipboard.
  * Do not allow escape sequences which expect a specific terminator (APC, DSC,
  OSC) to wait for forever - use a small timeout. This reduces the chance of
  the pane locking up completely when sent garbage (cat /dev/random or
  * Support SIGUSR2 to toggle logging on a running server, also generate the
  "out" log file with -vv not -vvvv.
  * Make set-clipboard a three state option: on (tmux both sends to outside
  terminal and accepts from applications inside); external (tmux sends outside
  but does not accept inside); and off.
  * Fix OSC 4 palette setting for bright foreground colours. GitHub issue 954.
  * Use setrgbf and setrgbb terminfo(5) capabilities to set RGB colours, if they
  are available. (Tc is still supported as well.)
  * Fix redrawing panes when they are resized several times but end up with the
  size unchanged (for example, splitw/resizep -Z/breakp).
  * Major rewrite of choose mode. Now includes preview, sorting, searching and
  tagging; commands that can be executed directly from the mode (for example,
  to delete one or more buffers); and filtering in tree mode.
  * choose-window and choose-session are now aliases of choose-tree (in the
  command-alias option).
  * Support OSC 10 and OSC 11 to set foreground and background colours.
  * Check the U8 capability to determine whether to use UTF-8 line drawing
  characters for ACS.
  * Some missing notifications for layout changes.
  * Control mode clients now do not affect session sizes until they issue
  refresh-client -C. new-session -x and -y works with control clients even if
  the session is not detached.
  * All new sessions that are unattached (whether with -d or started with no
  terminal) are now created with size 80 x 24. Whether the status line is on or
  off does not affect the size of new sessions until they are attached.
  * Expand formats in option names and add -F flag to expand them in option values.
  * Remember the search string for a pane even if copy mode is exited and entered
  * Some further BCE fixes (scroll up, reverse index).
  * Improvements to how terminals are cleared (entirely or partially).
Version: 2.7-bp150.2.2
* Sun Apr 15 2018
- Update to 2.7
  * Remove EVENT_* variables from environment on platforms where
    tmux uses them so they do not pass on to panes.
  * Fixed for hooks at server exit.
  * Remove SGR 10 (was equivalent to SGR 0 but no other terminal
    seems to do this).
  * Expand formats in window and session names.
  * Add -Z flag to choose-tree, choose-client, choose-buffer to
    automatically zoom the pane when the mode is entered and unzoom
    when it exits, assuming the pane is not already zoomed. This is
    now part of the default key bindings.
  * Add C-g to exit modes with emacs keys.
  * Add exit-empty option to exit server if no sessions (default = on)
  * Show if a filter is present in choose modes.
  * Add pipe-pane -I to to connect stdin of the child process.
  * Performance improvements for reflow.
  * Use RGB terminfo(5) capability to detect RGB colour terminals
    (the existing Tc extension remains unchanged).
  * Support for ISO colon-separated SGR sequences.
  * Add select-layout -E to spread panes out evenly (bound to E key).
  * Support wide characters properly when reflowing.
  * Pass PWD to new panes as a hint to shells, as well as calling
  * Performance improvements for the various choose modes.
  * Only show first member of session groups in tree mode (-G flag
    to choose-tree to show all).
  * Support %else in config files to match %if
  * Fix "kind" terminfo(5) capability to be S-Down not S-Up.
  * Add a box around the preview label in tree mode.
  * Show exit status and time in the remain-on-exit pane text
  * Correctly use pane-base-index in tree mode.
  * Change the allow-rename option default to off.
  * Support for xterm(1) title stack escape sequences
  * Correctly remove padding cells to fix a UTF-8 display problem
- build from release tarball instead of source (drops automake dep)
- rebase tmux-socket-path.patch
