But there might other things that come into play. In neovim setline() seems
to be much faster (when it's setting multiple lines).
For example:
======================================================
neovim lua
======================================================
local getlines = vim.api.nvim_buf_get_lines
local setlines = vim.api.nvim_buf_set_lines
local exec = vim.cmd
function LuaTest()
local totallen = 0
local start = vim.fn.reltime()
exec 'new'
exec 'call setline(1, range(100000))'
exec ('echom "After setting lines to range: "' ..
vim.fn.reltimestr(vim.fn.reltime(start)))
local bnr = vim.fn.bufnr()
local lines = getlines(bnr, 0, -1, false)
for i = 1, 100000 do
lines[i] = ' ' .. lines[i]
totallen = totallen + lines[i]:len()
end
setlines(bnr, 0, -1, false, lines)
exec ('echom ' .. totallen)
exec ('echom ' .. vim.fn.reltimestr(vim.fn.reltime(start)))
exec 'bwipe!'
end
======================================================
Result:
After setting lines to range: 0.062205
888890
0.200782
