Problem: w_wrow/col calculation in terminal_check_cursor is wrong when the terminal is smaller than the window. Common when there's a larger window open with the same terminal, or just after a resize (as refresh_size is deferred). Solution: don't calculate it; validate_cursor will correct it later if it's out-of-date. Note that the toplines set for the terminal (also before this PR) assume 'nowrap' (which is set by default for terminal windows), and that no weird stuff like filler lines are around. That means, for example, it's possible for the cursor to be moved off-screen if there's wrapped lines. If this happens, it's likely update_topline will move the cursor back on screen via validate_cursor or similar, but maybe this should be handled more elegantly in the future?
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 package
Pre-built packages for Windows, macOS, and Linux are found on the Releases page.

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
(orcmake -LAH build/
) contains the resolved values of all CMake variables.build/compile_commands.json
shows the full compiler invocations for each translation unit.
