Mars' Neovim config

Carefully crafted neovim config by me as an vim/neovim user and evangelist for more than 10 years. Use lazy.nvim as plugin manager.

Picker

• fzf (fuzzy finder for almost everything)
• fzf.vim (used with fzf)
• telescope.nvim (fuzzy finder written in Lua and support LSP)
• fzf-lua (fzf wrapper in Lua and support LSP and performs well)

Editor

• syntax-tree-surfer (text navigation and manipulation based on treesitter)

Git
