Problem: 1. `ctx_dirs_restore()` is the only chdir site that doesn't re-shorten buffer names; `post_chdir()`, `update_cwd()` and `do_autochdir()` all call `shorten_fnames(true)`. So after a temp window-context switch that moved the CWD, every buffer's `b_fname` is still relative to the other directory. ui2 renders messages in a float, and entering it is such a switch, so with a `:bcd` in a `BufReadPost` handler 'statusline' "%f" shows ".config/nvim/init.lua" while the CWD is already `~/.config/nvim`, and :write resolves the name against it: ``` E212: Can't open file for writing: no such file or directory ``` 2. `msg_multihl()` leaves `msg_ext_id` pointing at the caller's storage when nothing was emitted (e.g. 'msg_silent'): the reset only ran on a flush that produced chunks. The next message then ships a dead stack frame as its msg_show id. After ":silent write" the id is buf_write()'s `msg_id[MAXPATHL + 32]`: ``` id = "\0\0\0\0\0\0\0\0\29\0(<C6>k\24R\17p<C7><C7><C7>\1\0\0\0..." ``` Solution: 1. `shorten_fnames(true)` after restoring the CWD. Drop `cs_save_sfname`, which was a partial workaround for the same bug. 2. Release the id in `msg_multihl()`, where it is set and the caller's frame is still alive. Stop reading `.data.integer` out of a String union member.
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.

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.
