zeertzjq 7be8a8dda3 vim-patch:9.2.0932: NFA engine fallback can double free the compiled program (#41268)
Problem:  When the automatic regexp engine falls back to the
          backtracking engine in vim_regexec_string(), the compiled
          program is freed before the replacement is compiled; when
          saving the pattern fails from being out of memory the
          caller's "regprog" is left pointing to freed memory and
          is freed again.
Solution: Free the previous program only after compiling the
          replacement succeeded, like vim_regexec_multi() already
          does (Samuel Schlesinger).

Neovim is a project that seeks to aggressively refactor Vim in order to:

See the Introduction wiki page and Roadmap for more information.

Features

See :help nvim-features for the full list, and :help news for noteworthy changes in the latest version!

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 help lists all build targets.
  • build/CMakeCache.txt (or cmake -LAH build/) contains the resolved values of all CMake variables.
  • build/compile_commands.json shows the full compiler invocations for each translation unit.

Transitioning from Vim

See :help nvim-from-vim for instructions.
