I have a function in autoload\utils.lua
that changes buffer based on direction:
local function GoToBuffer(count, direction)
if count == 0 then
if direction == "forward" then
vim.api.nvim_command("bnext")
elseif direction == "backward" then
vim.api.nvim_command("bprevious")
else
vim.api.nvim_err_writeln("Bad argument " .. direction)
end
return
end
if vim.tbl_index(GetBufNums(), count) == -1 then
vim.fn.nvim_notify(string.format("Invalid bufnr: %d", count), 4, { title = "nvim-config" })
return
end
if direction == "forward" then
vim.api.nvim_command(string.format("buffer%d", count))
end
end
local function GetBufNums()
local buf_list = {}
for _, buf in ipairs(vim.api.nvim_get_buf_info({ buflisted = 1 })) do
buf_list[#buf_list + 1] = buf.bufnr
end
return buf_list
end
I mapped a key to this function using vim.keymap.set
:
local utils = require('autoload.utils')
keymap.set("n", "gb", '<cmd>:lua utils.GoToBuffer(v:count, "forward")<cr>', {})
keymap.set("n", "gB", '<cmd>:lua utils.GoToBuffer(v:count, "backward")<cr>', {})
When I use the keybind I get this error:
Error loading lua [string: "lua"]:1: function arguments expected near ','
The reason the code didn't work was because v:count
is how you would access the variable in vimscript whereas in lua its vim.v.count
