02a6b39db7 Improve logging of screen mode changes. 2021-06-10 07:43:44 +00:00

255802d8d7 Trim output overwritten by later text or clears completely rather than 
only in a few cases. This means we can better track when a line should
wrap. GitHub issue 2537.

8156d9ba41 Flush pending output before entering or exiting alternate screen rather 
than leaking it, oss-fuzz issue 29959.

change to come.

91d112bf12 There is no need to clear every line entirely before drawing to it, this 
means moving the cursor and messes up wrapping. Better to just clear the
sections that aren't written over. GitHub issue 2537.

ed786309cc Do not clear the wrapped flag on linefeeds if it is already set - this 
does not appear to be what applications want. GitHub issue 2478 and 2414.

2aa177d102 Do not eliminate redundant clears, the code is wrong and doing it 
correctly wouldn't be worth it. GitHub issue 2298.

068b92b051 The redraw callback could be fired with a NULL pane if it updates while 
in a mode, problem reported by Martin Vahlensieck.

2a4d4bda2b Allow UTF-8 characters of width 0 to be stored, it is useful to be able 
to put padding cells in as width 0.

35779d655d Fix definition of padding cells so they are not extended cells. 2020-05-25 18:55:36 +00:00

ecbdcc256f Add screen write flags instead of individual bits and fix line length 
calculation with padding.

d67245c734 Add a customize mode where keys and options may be browsed and changed, 
includes adding a brief description of each option. Bound to "C" by
default.

9605b080f6 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.

2391fe23ab Copy mode search improvements: 
- Add styles for the search marking styles (copy-mode-match-style and
  copy-mode-current-match-style).

- Show the current match (the one with the cursor on it) in a different style.

- Copying without a selection will copy the current match if there is one.

4a5182e665 Always start sync for output in panes that are not the active pane. 2020-04-20 15:49:05 +00:00
nicm
2083a6ea20 Change how sync works to always send the end sequence after all output 
is done when we are returning to the event loop (since we always move
the cursor at that point). Also a man fix from jmc.

100db552d1 A resize can realloc so cannot cache the value of the list pointer. 2020-04-18 17:20:25 +00:00

deffef6f13 Reset background colour on scrolled line. 2020-04-18 15:22:05 +00:00

ea5fdd5331 There is no point in keeping a bunch of different text buffers for each 
line when writing, we only need one as big as the line width - there
can't be any more text than that since newer will overwrite older.

e153b928ff Add formats for pane written/skipped bytes for debugging. 2020-04-18 07:19:28 +00:00
nicm
bbd6e899a8 There is no point allocating a new item and putting it on the list when 
the whole line is cleared line, there is never any point in doing it
more than once. Instead store the background colour alone.

need to flush everything.

there is a better chance more data will be on the way.

e3359f8349 Some minor performance improvements - most notably, don't search the 
input state table if the next character matches the same state as before.

3635b3cd6c Correctly clear underscore colour in grid_get_cell1, also fix struct 
grid_cell to avoid padding. Fixes increased memory use reported by Suraj
N Kurapati.

Kai Moschcau.

12255411f2 Allow menu items to be disabled by putting a - at the start of their 
name, rather than just including #[dim] which still allowed them to be
chosen.

06d58b3b7b screen_write_fast_copy can no longer assume the target screen is default 
(it isn't for the pane status lines).

979313832c Extend the #[] style syntax and use that together with previous format 
changes to allow the status line to be entirely configured with a single
option.

Now that it is possible to configure their content, enable the existing
code that lets the status line be multiple lines in height. The status
option can now take a value of 2, 3, 4 or 5 (as well as the previous on
or off) to configure more than one line. The new status-format array
option configures the format of each line, the default just references
the existing status-* options, although some of the more obscure status
options may be eliminated in time.

Additions to the #[] syntax are: "align" to specify alignment (left,
centre, right), "list" for the window list and "range" to configure
ranges of text for the mouse bindings.

The "align" keyword can also be used to specify alignment of entries in
tree mode and the pane status lines.

13f9a061ac Add a wrapper (struct style) around styles rather than using the 
grid_cell directly. There will be some non-cell members soon.
