Conversion in Lua: how to tabdo all the visible buffers without changing view of the current tab?

Question

Related to this post, how to tabdo all the visible buffers without changing view of the current tab?

function! TabLcd()
    let current_tab = tabpagenr()
    tabdo <commands>
    execute 'tabnext' current_tab
endfunction

nnoremap <silent> <leader>lcd :call TabLcd()<cr>

The code is written in Vimscript. I want to implement it in Lua.

Can anyone help me convert this?

Answer 1

My proposition would be:

function TabLcd()
    local current_tab = vim.fn.tabpagenr()
    vim.cmd("tabdo lcd %:p:h")
    vim.cmd("execute 'tabnext' " .. current_tab)
end

vim.api.nvim_set_keymap('n', '<leader>lcd', ':lua TabLcd()<CR>', { noremap = true, silent = true })

Answer 2

Lua format

function TabLcd()
    local current_tab = vim.fn.tabpagenr()
    vim.cmd("tabdo <commands>")
    vim.cmd("execute 'tabnext' " .. current_tab)
end

vim.api.nvim_set_keymap('n', '<leader>lcd', ':lua TabLcd()<CR>', { noremap = true, silent = true })

1. function TabLcd() defines a Lua function named TabLcd.

2. local current_tab = vim.fn.tabpagenr(): It stores the current tab page number in the current_tab variable using a Neovim built-in function vim.fn.tabpagenr().

3. vim.cmd("tabdo <commands>"): This line executes <commands> in all open tabs. You would replace with the specific commands you want to run in each tab. For example, if you want to run :command1 in each tab, you would use vim.cmd("tabdo command1").

4. vim.cmd("execute 'tabnext' " .. current_tab): After executing the commands in all tabs, it switches back to the original tab also defined as current_tab.

5. Set any keymap (in this case \lcd), And you're a go.
