Neovim working directory

by

Updated: 24 September 2025

Working directory of current window

:lua print(vim.fn.getcwd(0, 0))

Get current window number

:lua print(vim.api.nvim_get_current_win())

Get current tabpage number

:lua print(vim.api.nvim_get_current_tabpage())

This might be how it works:

  • Neovim (has own working_directory)
    • Tabpage num 1 (has own working_directory)
      • Window num 1010 (has own working_directory)
      • Window num 1011 (has own working_directory)
    • Tabpage num 2 (has own working_directory)
      • Window num 1012 (has own working_directory)
      • Window num 1013 (has own working_directory)

Updated: 23 October 2025

Notes – config of Intelephense PHP LSP

  • Neovim LSP log file: ~/.local/state/nvim/lsp.log
  • https://intelephense.com/
  • Install on your system npm install -g intelephense but is probably installed by Mason anyway.
  • See here: ./.local/share/nvim/mason/packages/intelephense/node_modules/intelephense
  • The root of a PHP project is identified by a .git folder or a composer.json file.
  • nvim-lspconfig intelephense docs
  • https://github.com/bmewburn
  • Perhaps an alternative to Intelephense https://github.com/phpactor/phpactor
  • Intelephense and Intelephense docs on GitHub https://github.com/bmewburn
  • Buying a Licence makes most of the LSP warnings disappear!
  • Try running command :LspInfo
