Lua
This release introduces "Nvim-Lua standard library". See ":help lua-stdlib".
89d7e24891#9463 Lua stdlib: vim.inspect, string functions
8e941c59ec#9740 Lua: generate documentation from docstrings
1cbe014569#9301 lua/stdlib: Introduce vim.shared
c83926cd0a#10123 Lua: introduce vim.loop (expose libuv event-loop)
81e1dbca99#10120 Lua: vim.schedule(cb)
1f54f68732#10688 Lua: minimal UTF-16 support needed for LSP
6fb0020df4#10513 Lua encoding support
c0993ed343 Lua: support getting UTF-32 and UTF-16 sizes of replaced text
b0e26199ec Lua: add {old_byte_size} to on_lines buffer change event
UI:
- The Nvim 0.3.4 UI protocol introduced line-based updates instead of
legacy char-based updates. Nvim 0.4 continues to evolve the UI
protocol. See ":help ui". Legacy UI clients are supported. See
":help api-contract".
9a1675b065#6619 Floating windows
- Can be (re)positioned, anchored, external.
- Are real windows showing real buffers. No shortcuts, hacks, or compromises.
- Support all features and API of normal windows, plus more.
6427894d89#8455 Multigrid: "windows drawn on separate grids"
- Windows are logically isolated internally.
- Windows are sent to UIs as distinct objects, so that UIs can control
layout instead of being stuck with the classic TUI layout.
- Per-window font-size, dimenions, line-spacing.
- Compositor: Internal subsystem for composing grids.
3855204f58#6917 UIEnter, UILeave
788bcbba24#9923 ui: ":syn blend=", 'winblend'
7cf7c0a0b8#9575 ui: 'redrawdebug' option for flexible debugging of redrawing
5c836d2ef8#9607 wildoptions=pum (enabled by default)
37f8df8824#9571 UI: 'pumblend' option for semi-transparent popupmenu
c403a95a52#9446 Visual: highlight char-at-cursor
- Traditionally Vim's visual selection does "reverse mode", which
perhaps conflicts with the non-blinking block cursor. But
'guicursor' defaults to a vertical bar for selection=exclusive, and
this confuses users who expect to see the text highlighted.

58f505dc74#9829 startup: remove TUI init special-case
Historically Vim/Nvim does backflips to handle input and show messages
before a UI is available. This logical contradiction was already fixed
for remote UIs (#9024c236e80cf3). Fixing it also for the TUI avoids
problems on Windows, simplifies the logic, and avoids races like #9959.
libvterm now advertises a version number, so we can specify the minimum
required version. And this is necessary because there were breaking
changes in its API.
ref 2a590e2293
ref https://github.com/neovim/neovim/issues/10991
We are using "LIBFOO" prefixes for `LIBFOO_INCLUDE_DIRS` etc, and
therefore need to use this for the PREFIX with LibFindMacros also, so
that `"${${PREFIX}_FIND_VERSION}"` gets handled there properly.
The alternative would be to either manually handle/set the upper/mixed case
variants of those variable additionally, which is not as easy.
Keeping the existing names is useful for packagers.
Before this the version requirements with
`find_package(Unibilium 2.0 REQUIRED)` was not handled (a49cf5126), and
it prepares for using a required version with libvterm
(initially/wrongly ported in 1896c72a5).
This avoids errors when using "make lint", but "flake8" is not
available. We do not want to install it then via third-party.
On CI "make pylint" is used explicitly.
* build: require unibilium>=2.0
This also ports FindUnibilium to LibFindMacros, which was planned
anyway, and makes the version check easier.
With an older Unibilium our fallback code in `terminfo_from_builtin`
will not work (because it assumes the new data structures from 2.0.0 [1]),
and nvim would crash later because of `ut` being NUL.
1: 42f3cdd284
Might not be necessary anymore, at least it is fine on gcc 9.1, and
since the bug is still open/unresolved, something else might have fixed
it.
Ref: 4b81f627c
Ref: #7083
`check_c_compiler_flag(-Wno-doesnotexist …)` is successful always,
apparently for all "no-" prefixes.
Therefore check for the flag itself (without "no-" prefix).
I am seeing a warning if the source fails to compile:
> cc1: warning: unrecognized command line option ‘-Wno-meh’
Which is turned into an error with `-Werror`:
> cc1: error: unrecognized command line option ‘-Wno-meh’ [-Werror]
But when it compiles successfully, there is no warning/error.
gcc (GCC) 9.1.0.
* build: FindLibIntl: fix warning about CMP0075
The common pattern elsewhere to set this only during the check, and here
it was not unset, resulting in a warning later (on Alpine 3.10):
-- Found Iconv
-- Looking for pthread.h
CMake Warning (dev) at /usr/share/cmake/Modules/CheckIncludeFile.cmake:80 (message):
Policy CMP0075 is not set: Include file check macros honor
CMAKE_REQUIRED_LIBRARIES. Run "cmake --help-policy CMP0075" for policy
details. Use the cmake_policy command to set the policy and suppress this
warning.
CMAKE_REQUIRED_LIBRARIES is set to:
/usr/lib/libintl.so
For compatibility with CMake 3.11 and below this check is ignoring it.
Call Stack (most recent call first):
/usr/share/cmake/Modules/FindThreads.cmake:105 (CHECK_INCLUDE_FILE)
CMakeLists.txt:482 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.
-- Looking for pthread.h - found
* build: remove lists / REMOVE_ITEM around check_c_source_compiles
- Move .luacheckrc to root, add read_globals=vim
- Simplify lualint target, run it on all lua files
- Lint preload.lua, but ignore W211
- Remove testlint target, included in lualint (and lint)
- Clean up .luacheckrc
Required after d33aaa0f5.
Does not really make a difference, since the VERSION is not handled with
our FindLibLUV (due to missing pkg-config information
(https://github.com/luvit/luv/issues/354)).
Keeps using add_definitions for compatibility with older CMake.
Newer CMake (3.12) would have `add_compile_definitions`, but it is not
required, since `add_defitions` was meant to be used for
compile/preprocessor definitions initially anyway.
Ref: https://github.com/neovim/neovim/pull/4389
Just set it from `${CMAKE_HOST_SYSTEM_NAME}` directly, instead of passing it
from the main CMake file (CMAKE_SYSTEM_NAME defaults to it, but is empty
in script mode).
Initially added in 9ce81f7b2, but then even used with unrelated commands
(that do not use RunTests.cmake, e.g. 221f6fffa).
- Minimum required libuv is now v1.12
- Because `uv_os_getenv` requires allocating, we must manage a map
(`envmap` in `env.c`) to maintain the old behavior of `os_getenv` .
- free() map-items after removal. khash.h does not make copies of
anything, so even its keys must be memory-managed by the caller.
closes#8398closes#9267
There was never any investigation done to determine whether using
jemalloc was actually a net benefit for nvim. It has been a portability
limitation and adds another factor to consider when triaging issues.
Note about shada.c:
- shada_read_next_item_start was intentionally shadowing `unpacked` and
`i` because many of the macros (e.g. ADDITIONAL_KEY) implicitly
depended on those variable names.
- Macros were changed to parameterize `unpacked` (but not `i`). Macros
like CLEAR_GA_AND_ERROR_OUT do control-flow (goto), so any other
approach is messy.
Besides the "visible" improvements, this release features numerous
internal improvements to the UI/screen code and test infrastructure.
Numerous patches were merged from Vim, which are not mentioned below.

As of CMake 3.12, check_include_files() also link the check executable
against the libraries listed in CMAKE_REQUIRED_LIBRARIES. Therefore we
should unset the CMAKE_REQUIRED_* variables after each respective use to
avoid them unnecessarily bleeding into other checks.
