I am using neovim 0.5 and want to write a custom function to use with telescope.nvim.
I need to get the file path of the current buffer I execute the function. I have been unable to find how to do this in the nvim Lua API docs.
vim.nvim_get_current_buf gets the buffer number, 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)
