Vim-fork focused on extensibility and usability
b04286a187
The removes the previous restriction that nvim_buf_set_extmark() could not be used to highlight arbitrary multi-line regions The problem can be summarized as follows: let's assume an extmark with a hl_group is placed covering the region (5,0) to (50,0) Now, consider what happens if nvim needs to redraw a window covering the lines 20-30. It needs to be able to ask the marktree what extmarks cover this region, even if they don't begin or end here. Therefore the marktree needs to be augmented with the information covers a point, not just what marks begin or end there. To do this, we augment each node with a field "intersect" which is a set the ids of the marks which overlap this node, but only if it is not part of the set of any parent. This ensures the number of nodes that need to be explicitly marked grows only logarithmically with the total number of explicitly nodes (and thus the number of of overlapping marks). Thus we can quickly iterate all marks which overlaps any query position by looking up what leaf node contains that position. Then we only need to consider all "start" marks within that leaf node, and the "intersect" set of that node and all its parents. Now, and the major source of complexity is that the tree restructuring operations (to ensure that each node has T-1 <= size <= 2*T-1) also need to update these sets. If a full inner node is split in two, one of the new parents might start to completely overlap some ranges and its ids will need to be moved from its children's sets to its own set. Similarly, if two undersized nodes gets joined into one, it might no longer completely overlap some ranges, and now the children which do needs to have the have the ids in its set instead. And then there are the pivots! Yes the pivot operations when a child gets moved from one parent to another. |

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.
Managed packages are in Homebrew, Debian, Ubuntu, Fedora, Arch Linux, Void Linux, Gentoo, and more!
Install from source
See the Building Neovim wiki page 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.
