- Drop the remaining undefined "shFunctionStart" references
(gone in v7.2b.000, c236c16d0).
- Revise nestable contexts where function definitions are
supported:
* Stop looking for function definitions in arithmetic
expressions.
* Recognise function definitions enclosing other function
definitions.
- In addition to grouping commands "{}" and "()", also match
other compound commands (e.g. "if"; see "shFunctionCmd*")
whenever these commands are supported as complete function
bodies.
- Balance body delimiters "(" and ")" for "shFunctionFour"
in Bash; match such function bodies whenever the use of
the function parameter list "()" token is optional, i.e.
when the "function" reserved word is present.
- Enable the use of "shFunctionFour" definitions.
- Do not claim optional leading whitespace characters before
a matched function definition.
- Prefer patterns with ASCII atoms (e.g. "\h") to equivalent
collections (e.g. "[A-Za-z_]") for speed.
- Accommodate word-boundary assertions in function name
patterns to names that may start and/or end with supported
non-word characters, e.g. "@test:".
- Match more valid function names in Bash: non-ASCII names,
non-word names.
- Allow for function names with "do", "done", etc. prefixes;
confine these name checks to "shDoError" and "shIfError".

Neovim is a project that seeks to aggressively refactor Vim in order to:
- Simplify maintenance and encourage contributions
- Split the work between multiple developers
- Enable advanced UIs without modifications to the core
- Maximize extensibility
See the Introduction wiki page and Roadmap for more information.

- API access from any language including C/C++, C#, Clojure, D, Elixir, Go, Haskell, Java/Kotlin, JavaScript/Node.js, Julia, Lisp, Lua, Perl, Python, Racket, Ruby, Rust
- Embedded, scriptable terminal emulator
- Asynchronous job control
- Shared data (shada) among multiple editor instances
- XDG base directories support
- Compatible with most Vim plugins, including Ruby and Python plugins

Install from package
Pre-built packages for Windows, macOS, and Linux are found on the Releases page.
Managed packages are in Homebrew, Debian, Ubuntu, Fedora, Arch Linux, Void Linux, Gentoo, and more!
Install from source
See BUILD.md and supported platforms for details.
The build is CMake-based, but a Makefile is provided as a convenience. After installing the dependencies, run the following command.
make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install
To install to a non-default location:
make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_INSTALL_PREFIX=/full/path/
make install
CMake hints for inspecting the build:
cmake --build build --target helplists all build targets.build/CMakeCache.txt(orcmake -LAH build/) contains the resolved values of all CMake variables.build/compile_commands.jsonshows the full compiler invocations for each translation unit.
Transitioning from Vim
See :help nvim-from-vim for instructions.
