577c0e3e5a Use __unused rather than rolling our own. 2015-11-18 14:27:44 +00:00

c5689a5a40 Long overdue change to the way we store cells in the grid: now, instead 
of storing a full grid_cell with UTF-8 data and everything, store a new
type grid_cell_entry. This can either be the cell itself (for ASCII
cells), or an offset into an extended array (per line) for UTF-8
data.

This avoid a large (8 byte) overhead on non-UTF-8 cells (by far the
majority for most users) without the complexity of the shadow array we
had before. Grid memory without any UTF-8 is about half.

The disadvantage that cells can no longer be modified in place and need
to be copied out of the grid and back but it turned out to be lot less
complicated than I expected.

1b86f520ea Nuke the utf8 and status-utf8 options and make tmux only a UTF-8 
terminal. We still support non-UTF-8 terminals outside tmux, but inside
it is always UTF-8 (as when the utf8 and status-utf8 options were on).

69e0b8326a Support UTF-8 key bindings by expanding the key type from int to 
uint64_t and converting UTF-8 to Unicode on input and the reverse on
output. (This allows key bindings, there are still omissions - the
largest being that the various prompts do not accept UTF-8.)

01defc9f49 Because pledge(2) does not allow us to pass directory file descriptors 
around, we can't use file descriptors for the working directory because
we will be unable to pass it to a privileged process to tell it where to
read or write files or spawn children. So move tmux back to using
strings for the current working directory. We try to check it exists
with access() when it is set but ultimately fall back to ~ if it fails
at time of use (or / if that fails too).

bf635e7741 Rewrite of tmux mouse support which was a mess. Instead of having 
options for "mouse-this" and "mouse-that", mouse events may be bound as
keys and there is one option "mouse" that turns on mouse support
entirely (set -g mouse on).

See the new MOUSE SUPPORT section of the man page for description of the
key names and new flags (-t= to specify the pane or window under mouse
as a target, and send-keys -M to pass through a mouse event).

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.

nicm
3dbacbb62b Add support for named buffers. If you don't name a buffer, things work 
much as before - buffers are automatically named "buffer0000",
"buffer0001" and so on and ordered as a stack. Buffers can be named
explicitly when creating ("loadb -b foo" etc) or renamed ("setb -b
buffer0000 -n foo"). If buffers are named explicitly, they are not
deleted when buffer-limit is reached. Diff from J Raynor.

nicm
945339b443 Allow replacing each of the many sets of separate foo-{fg,bg,attr} 
options with a single foo-style option. For example:

    set -g status-fg yellow
    set -g status-bg red
    set -g status-attr blink

Becomes:

    set -g status-style fg=yellow,bg=red,blink

The -a flag to set can be used to add to rather than replace a style. So:

    set -g status-bg red

Becomes:

    set -ag status-style bg=red

Currently this is fully backwards compatible (all *-{fg,bg,attr} options
remain) but the plan is to deprecate them over time.

time now I've configured emacs to make them displayed in really annoying
colours...

the rest to reduce lint output.

a78cc98c8b Cleanup by moving various (mostly horrible) little bits handling UTF-8 grid 
data into functions in a new file, grid-utf8.c, and use sizeof intead of
UTF8_DATA.

Also nuke trailing whitespace from tmux.1, reminded by jmc.

38df960e68 Add mode keys to move the cursor to the top, middle and bottom of the screen. 
H/M/L in vi mode and M-R/M-r in emacs (bottom of screen not bound in emacs).

4bc0f6e7e9 Clean up by introducing a wrapper struct for mouse clicks rather than passing 
three u_chars around.

As a side-effect this fixes incorrectly rejecting high cursor positions
(because it was comparing them as signed char), reported by Tom Doherty.

9400fdac77 Make C-Up and C-Down in copy mode scroll the screen up and down one line 
without moving the cursor, like Up and Down in scroll mode (which will shortly
disappear).

f817a338d0 When moving up or down in copy mode, save the cursor position and size of the 
last line with content (width != 0) and use it to determine if the cursor
should be at the end of the line. Fixes problem of the cursor always jumping to
the end of the line when scrolling past a blank line.

feaf91ab93 Add a "delete line" key when editing in the status line or the search up/down 
prompt. C-u with emacs keys, d with vi.
 2009-08-18 07:23:43 +00:00
Nicholas Marriott
c828c2f366 Add (naive) searching and goto line in copy mode. Searching is C-r and C-s with 
emacs keys, / and ? with vi; n repeats the search again with either key
set. All searching wraps the top/bottom. Goto line is g for both emacs and vi.

The search prompts don't have full line editing, just simple append and delete
characters.

Also sort the mode keys list in tmux.1.

7a359c00ac vi(1)-style half page scroll in copy and scroll modes. Move the vi full page 
scroll key to C-b instead of C-u and use C-u/C-d for half page scrolling with
vi keys. In emacs mode, half page scrolling is bound to M-Up and M-Down.

Suggested by merdely (about a year ago :-)).

39154402e5 Scroll by two less than the number of lines in the screen, like emacs, rather 
than by the entire screen, to make it easier to pull things out from under the
line indicator. Suggested by claudio.

3026118c70 Allowing copy mode to scroll left and right is annoying, so limit it to the 
real screen width. To indicate the cursor is at the end of the line rather than
the cell before, put a '$' in the last cell.

Also clear the selection when the terminal is resized to avoid tmux getting
confused.

06ddd3dcf8 Add a flags member to the grid_line struct and use it to differentiate lines 
wrapped at the screen edge from those terminated by a newline. Then use this
when copying to combine wrapped lines together into one.

5e01b6d663 Change the way the grid is stored, previously it was: 
- a two-dimensional array of cells;
- a two-dimensional array of utf8 data;
- an array of line lengths.

Now it is a single array of a new struct grid_line each of which represents a
line and containts the length and an array of cells and an array of utf8 data.

This will make it easier to add additional per-line members, such as flags.

bcddddf98d If colours are not supported by the terminal, try to emulate a coloured 
background by setting or clearing the reverse attribute.

This makes a few applications which don't use the reverse attribute themselves
a little happier, and allows the status, message and mode options to have
default attributes and fg/bg options that work as expected when set as reverse.

86785004ba Next step towards customisable mode keys: build each default table of keys into 
a named tree on start and use that for lookups. Also add command to string
translation tables and modify list-keys to show the the mode key bindings (new
-t argument).

d95274c5f2 Change mode key bindings from big switches into a set of tables. Rather than 
lumping them all together, split editing keys from those used in choice/more
mode and those for copy/scroll mode.

Tidier and clearer, and the first step towards customisable mode keys.

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.
