Non-Intrusive Neovim-Config

This environment depends on various plugins, including a plugin manager.
Simply clone this repository into $HOME/.config/ after neovim is built.
All files in this repository cannot be used with vim.
To fully use tools in this repository, install lazygit for lazygit, ripgrep for telescope, tree-sitter-cli for treesitter, macism (only on macOS) for better InsertLeave experience, latexmk for vimtex, a suitable PDF viewer depending on your OS for vimtex, and dictionary and deno for skkeleton.

This Neovim setup focuses on manual editing efficiency. It may not suit those who rely on completion or automation, as these features are intentionally disabled.
