* Instead of overloading the line clear function to mean free ifnicm2017-08-30
| | | | | | | background is default (8), introduce an explicit free function and use it where a free alone is needed. Likewise, use memmove directly rather than grid_move_lines where it makes sense. Based on a memory leak fix by Dan Aloni in GitHub issue 1051.

* Collect sequences of printable ASCII characters and process themnicm2017-02-08
| | | | | | | | | | | | | | | together instead of handling them one by one. This is significantly faster. Sequences are terminated when we reach the end of the line, fill the internal buffer, or a different character is seen by the input parser (an escape sequence, or UTF-8). Rather than writing collected sequences out immediately, hold them until it is necessary (another screen modification, or we consume all available data). This means we can discard changes that would have no effect (for example, lines that would just be scrolled off the screen or cleared). This reduces the total amount of data we write out to the terminal - not important for fast terminals, but a big help with slow (like xterm).

* Add support for BCE (background colour erase). This makes various escapenicm2016-10-13
| | | | | | | | | | | | sequences (notable EL and ED but also IL, DL, ICH, DCH) create blank cells using the current background colour rather than the default colour. On modern systems BCE doesn't really have many benefits, but most other terminals now support it, some (lazy) applications rely on it, and it is not hard to include now that we have pane background colours anyway. Mostly written by Sean Haugh.

* Remember the number of lines scrolled into the history (versus clearednicm2016-09-02

* Don't update cells in each block of data read from a pane immediately,nicm2016-07-15
| | | | | | instead track them as change (dirty) and update them once at the end, saves much time if repeatedly writing the same cell. Also fix comparison of cells being equal in a few places (memcmp is not enough).

| | | | | | | | wasting unnecessary space. The 'Tc' flag must be set in the external TERM entry (using terminal-overrides or a custom terminfo entry), if not tmux will map to the closest of the 256 or 16 colour palettes. Mostly from Suraj N Kurapati, based on a diff originally by someone else.

* Long overdue change to the way we store cells in the grid: now, insteadnicm2015-11-13
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | 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.
