Neovim working directory

by

Updated: 01 March 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)

Neovim Intelephense

Updated: 03 November 2024

Notes to assist with config and use of the 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.

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

Magic

\v characters which follow, except a-zA-Z0-9_, have special meaning.
\V characters which follow have their literal meaning and must be preceded by \ to activate their special meaning.
