- Removed term.c, term.h and term_defs.h
- Tests for T_* values were removed. screen.c was simplified as a
consequence(the best strategy for drawing is implemented in the UI layer)
- Redraw functions now call ui.c functions directly. Updates are flushed with
`ui_flush()`
- Removed all termcap options(they now return empty strings for compatibility)
- &term/&ttybuiltin options return a constant value(nvim)
- &t_Co is still available, but it mirrors t_colors directly
- Remove cursor tracking from screen.c and the `screen_start` function. Now the
UI is expected to maintain cursor state across any call, and reset it when
resized.
- Remove unused code

- Remove abstract_ui global, now it is always active
- Remove some terminal handling code
- Remove unused functions
- Remove HAVE_TGETENT/TERMINFO/TERMIOS/IOCTL #ifdefs
- Remove tgetent/terminfo from version.c
- Remove curses/terminfo dependencies
- Only start/stop termcap when starting/exiting the program

Macro cleanup

Regarding dict_lookup() in eval.c: both definitions are the same, the
only difference being the spacing between the indirection operator and
the indentation level.

Before sending a resize command to the UIs, flush the current output buffer to
ensure no redraw commands for a screen with invalid size are processed.

This code is required for screen.c to set a vertical scroll region, which is a
great optimization when scrolling vertically split windows.

At 31c8440fee0bd694093d83af5dee20e3c3dc876c, some variables were changed
from int to long, to avoid -Wconversion errors. Long type was the
appropiate one because getdigits() was returning a long.
Now that we have get_int_digits() and get_long_digits(), we can revert
mentioned variables to int, and use get_int_digits() without having
-Wconversion warnings.

Problem : getdigits() currently returns a long, but at most places,
return value is casted (unsafely) into an int. Making casts
safe would introduce a lot of fuss in the form of assertions
checking for limits.
Note : We cannot just change return type to int, because, at some
places, legitimate long values are used. For example, in
diff.c, for line numbers.
Solution : Introduce new functions:
- get_digits() : Gets an intmax_t from a string.
- get_int_digits() : Wrapper for ints.
- get_long_digits() : Wrapper for longs.
And replace getdigits() invocations by the appropiate
wrapper invocations.

get_long_from_buf() seems not to be used anywhere, and is the only place
where instances of long_u remain at term.c.

Notes regarding the removal of specific items:
- Aztec C: only on the Amiga.
- mch_check_win(): doesn't exist anymore.
- Comment in ex_cmds.c: It seems the context for this comment was
removed, but the comment was inadvertantly left alone.

This is how Nvim behaves when the "abstract_ui" termcap is activated:
- No data is written/read to stdout/stdin by default.
- Instead of sending data to stdout, ui_write will parse the termcap codes
and invoke dispatch functions in the ui.c module.
- The dispatch functions will forward the calls to all attached UI
instances(each UI instance is an implementation of the UI layer and is
registered with ui_attach).
- Like with the "builtin_gui" termcap, "abstract_ui" does not contain any key
sequences. Instead, vim key strings(<cr>, <esc>, etc) are parsed directly by
input_enqueue and the translated strings are pushed to the input buffer.
With this new input model, its not possible to send mouse events yet. Thats
because mouse sequence parsing happens in term.c/check_termcodes which must
return early when "abstract_ui" is activated.
|
| |
|
|
| |
This is now always defined.
|
| | |
|
| |
|
|
|
|

Nvim now relies much less on setting terminal mode to cooked mode, remove most
calls to settmode, except for those that happen on startup or when suspending.
Eventually even those will be handled by the UI layer.

Switch from POSIX's write() to fwrite(stdout,...) and disable buffering
since vim buffers output explicitly and flushes when needed, like when a
key is typed.

These functions only used to call another os_* function, so remove them and
replace all occurences in the project.

Problem: When 'ttymouse' is set to 'uxterm' the xterm version is not
requested. (Tomas Janousek)
Solution: Do not mark uxterm as a conflict mouse and add
resume_get_esc_sequence().

Problem: Making 'ttymouse' empty after the xterm version was requested
causes problems. (Elijah Griffin)
Solution: Do not check for DEC mouse sequences when the xterm version was
requested. Also don't request the xterm version when DEC mouse
was enabled.

This option makes nvim run in "embedded mode", which creates an API channel via
stdin/stdout and disables all terminal-related code

gettimeofday() is not portable, replace with os_hrtime() wherever possible.
The new code should behave equivalently to the old implementation.
Because of this, HAVE_GETTIMEOFDAY is no longer necessary To be able to
handle double clicks.

`-Wstrict-prototypes` warn if a function is declared or defined without
specifying the argument types.
This warning disallow function prototypes with empty parameter list.
In C, a function declared with an empty parameter list accepts an
arbitrary number of arguments when being called. This is for historic
reasons; originally, C functions didn't have prototypes, as C evolved
from B, a typeless language. When prototypes were added, the original
typeless declarations were left in the language for backwards
compatibility.
Instead we should provide `void` in argument list to state
that function doesn't have arguments.
Also this warning disallow declaring type of the parameters after the
parentheses because Neovim header generator produce no declarations for
old-stlyle prototypes: it expects to find `{` after prototype.
