How do I look up Neovim Lua API functions?

1

I looked at the official API page: https://neovim.io/doc/user/api.html, but it doesn’t seem to have all the functions I can call to write functions in init.lua. I got this answer on Vi StackExchange with a lua snippet that calls vim.fn.line(). What is it and where is it documented? and what are other things I should know about Neovim Lua / APIs?

Any function that you can call in vimscript you can call from lua using vim.fn. prefix. To get help for function In question you can run :h line().

If you have Telescope, you can use :Telescope builtin, it will popup a list where you can subsequently search for help_tags.

I have the following keybinding for that:

vim.keymap.set('n', '<leader>sh', builtin.help_tags, { desc = 'Help' })
