Design - Enable commenting support only through `gc` mappings for simplicity. No ability to configure, no Lua module, no user commands. Yet. - Overall implementation is a simplified version of 'mini.comment' module of 'echasnovski/mini.nvim' adapted to be a better suit for core. It basically means reducing code paths which use only specific fixed set of plugin config. All used options are default except `pad_comment_parts = false`. This means that 'commentstring' option is used as is without forcing single space inner padding. As 'tpope/vim-commentary' was considered for inclusion earlier, here is a quick summary of how this commit differs from it: - **User-facing features**. Both implement similar user-facing mappings. This commit does not include `gcu` which is essentially a `gcgc`. There are no commands, events, or configuration in this commit. - **Size**. Both have reasonably comparable number of lines of code, while this commit has more comments in tricky areas. - **Maintainability**. This commit has (purely subjectively) better readability, tests, and Lua types. - **Configurability**. This commit has no user configuration, while 'vim-commentary' has some (partially as a counter-measure to possibly modifying 'commentstring' option). - **Extra features**: - This commit supports tree-sitter by computing `'commentstring'` option under cursor, which can matter in presence of tree-sitter injected languages. - This commit comments blank lines while 'tpope/vim-commentary' does not. At the same time, blank lines are not taken into account when deciding the toggle action. - This commit has much better speed on larger chunks of lines (like above 1000). This is thanks to using `nvim_buf_set_lines()` to set all new lines at once, and not with `vim.fn.setline()`.
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

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.
