I am using Neovim 0.5 and want to write a custom function to use with telescope.nvim.

I need to get the path of the file loaded in the current buffer before I can execute the function. I have been unable to find how to do this after reading the Neovim Lua API documentation.

So far I've found that vim.api.nvim_get_current_buf() returns the current buffer number, but how do I get the full file path of the current buffer?

You can access the full path to the file in the current buffer using vim.api.nvim_buf_get_name(0), where 0 for buffer id means "the current buffer".

The function you are looking for is:

vim.fn.expand('%')

% is expanded to the current filename.

See :help expand() for more wildcards like %.

vim.fn.expand('%:p')

Gives the full path regardless of the current path (CWD). Without the %:p modifier, it might give only the relative path. See :help filename-modifiers (or %:p)
