Problem: Only terminals with up to 256 colors work properly.
Solution: Use the 256 color behavior for all terminals with 256 or more
colors. (Robert de Bath)

Problem: Using searchpair() with a skip expression that uses syntax
highlighting sometimes doesn't work. (David Fishburn)
Solution: Reset next_match_idx. (Christian Brabandt)

- `syntax_on` is documented. Rather than introduce a new undocumented
VimL global `g:syntax_off`, use a module-local flag.
- Rename "maybe" functions to follow style guidelines (use standard
module prefix)
Problem: Crash when using "syn keyword x c". (Dominique Pelle)
Solution: Initialize the keyword tabble. (Raymond Ko, PR 397)

Regarding the individual items in the header:
`Vim - Vi improved by Bram Moolenar`
Bram Moolenar is already mentioned throughout the documentation, as
well as the intro screen.
`:help uganda`
It's already shown to all users who don't use `shortmess+=I` upon
starting nvim, and is already placed prominently in help.txt, i.e.,
`:help` run with no arguments.
`:help credits`
Already mentioned near the top of help.txt.
`README.md`
Already mentioned in develop.txt.
We already use wrappers for allocation, the new `xfree` function is the
equivalent for deallocation and provides a way to fully replace the malloc
implementation used by Neovim.
The CENT macro was set condionally depending on the FEAT_GUI constant that was
removed a long time ago.
Other small refactorings:
- remove obsolete TERM= flags
- sort and indent lines in array for readability
- 'Conceal' and 'WildMenu' were moved from highlight_init_{dark,light}[]
to highlight_init_both[] since the same values were used anyway
This commit integrates libvterm with Neovim and implements a terminal emulator
with nvim buffers as the display mechanism. Terminal buffers can be created
using any of the following methods:
- Opening a file with name following the "term://[${cwd}//[${pid}:]]${cmd}"
URI pattern where:
- cwd is the working directory of the process
- pid is the process id. This is just for use in session files where a pid
would have been assigned to the saved buffer title.
- cmd is the command to run
- Invoking the `:terminal` ex command
- Invoking the `termopen` function which returns a job id for automating the
terminal window.
Some extra changes were also implemented to adapt with terminal buffers. Here's
an overview:
- The `main` function now sets a BufReadCmd autocmd to intercept the term:// URI
and spawn the terminal buffer instead of reading the file.
- terminal buffers behave as if the following local buffer options were set:
- `nomodifiable`
- `swapfile`
- `undolevels=-1`
- `bufhidden=hide`
- All commands that delete buffers(`:bun`, `:bd` and `:bw`) behave the same for
terminal buffers, but only work when bang is passed(eg: `:bwipeout!`)
- A new "terminal" mode was added. A consequence is that a new set of mapping
commands were implemented with the "t" prefix(tmap, tunmap, tnoremap...)
- The `edit` function(which enters insert mode) will actually enter terminal
mode if the current buffer is a terminal
- The `put` operator was adapted to send data to the terminal instead of
modifying the buffer directly.
- A window being resized will also trigger a terminal resize if the window
displays the terminal.
ASan spotted a problem when using 'set background={light,dark}' with
color scheme solarized.
While loading the colors for color scheme 'g:colors_name', the pointer
on the value for this variable can become invalid, because of an 'unlet
colors_name' (part of an :highlight clear, syntax.c:6173).
To prevent the use of the freed value, decouple the value from
'g:colors_name' before calling load_colors() with it.
- 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
- msg_use_printf will return true if there are no attached UIs(
messages will be written to stdout)
- Remove `ex_winpos`(implement `:winpos` with `ex_ni`)
These were found with -Wunused-macros. There are many more macros which
triggered that warning, but they were primarily part of larger sets of
macros so leave them alone.
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.
- Set 't_Co' to 256 at startup. The value can be changed by the user for
compatibility with terminals that are less capable.
- `has('gui_running')` will return 1 if at least one rgb UI is attached.
Even though these changes are hacky, they are necessary to make the transition
to the new UI architecture smoother.
