Vim-fork focused on extensibility and usability

Inherited signal mask may block SIGCHLD, which causes libuv to hang at epoll_wait. Closes #5230 Helped-by: Nicolas Hillegeer <nicolas@hillegeer.com> Helped-by: John Szakmeister <john@szakmeister.net> Note: the #pragma gymnastics are a workaround for broken system headers on macOS. signal.h: int sigaddset(sigset_t *, int); #define sigaddset(set, signo) (*(set) |= __sigbits(signo), 0) sys/_types/_sigset.h: typedef __darwin_sigset_t sigset_t; sys/_types.h: typedef __uint32_t __darwin_sigset_t; /* [???] signal set */ sigset_t is defined as unsigned int, but the sigaddset() ORs it with an int, mixing the types. So GCC generates a sign-conversion warning: sig.c:9:13: warning: implicit conversion changes signedness: 'int' to 'unsigned int' [-Wsign-conversion] (*(&s) |= __sigbits((sigset_t) 20), 0); ~~ ^~~~~~~~~~~~~~~~~~~~~~~~ 1 warning generated. System headers are normally ignored when the compiler generates warnings: https://gcc.gnu.org/onlinedocs/cpp/System-Headers.html > GCC gives code found in system headers special treatment. All warnings, > other than those generated by ‘#warning’ (see Diagnostics), are suppressed > while GCC is processing a system header. Macros defined in a system header > are immune to a few warnings wherever they are expanded. This immunity is > granted on an ad-hoc basis, when we find that a warning generates lots of > false positives because of code in macros defined in system headers. Instead of the #pragma workaround, we could cast the sigset_t pointer: # if defined(__APPLE__) sigaddset((int *)&mask, SIGCHLD); # else sigaddset(&mask, SIGCHLD); # endif but that could break if the headers are later fixed. |

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 the implementation of new/modern UIs without modifications to the core
- Improve extensibility with a new plugin architecture
For more details, see the wiki!
What's been done so far
- RPC API based on MessagePack
- Embedded terminal emulator
- Asynchronous job control
- Shared data (shada) among multiple editor instances
- XDG base directories support
- libuv-based platform/OS/"mch" layer
- Pushdown automaton input model
- 1000s of new tests
- Legacy tests converted to Lua tests
See :help nvim-features for a comprehensive list.
What's being worked on now
See the Roadmap.
How do I get it?
There is a formula for OSX/homebrew, a PKGBUILD for Arch Linux, RPM, deb, and more. See the wiki!
