Describe the question

Tried to use init.lua explained in this discussion but I'm getting:

Error: Lua runtime failed

Caused by:
    syntax error: [string "init.lua"]:29: 'then' expected near '='

Provably because linemode process has changed?
How to fix?

Anything else?

The error message doesn't seem to be directly related to the linemode functionality itself.

I tested the solution provided in the discussion you shared, and it still works.
You should see the following notification about the changes in the API:

The `created`, `modified`, `accessed`, `length`, and `permissions` properties of `Cha` have been renamed in Yazi v0.4.

Please use the new `btime`, `mtime`, `atime`, `len`, and `perm` instead, in your {id}. See #1772 for details: https://github.com/sxyazi/yazi/issues/1772

To update the solution to match the current properties, simply change modified to mtime, like this:

 function Linemode:custom()
        local year = os.date("%Y")
-       local time = (self._file.cha.modified or 0) // 1
+       local time = (self._file.cha.mtime or 0) // 1

        if time > 0 and os.date("%Y", time) == year then
                time = os.date("%b %d %H:%M", time)

So my suggestion would be to double-check the code inside your init.lua file.

Repaced 'modified' with 'mtime' and 'permissions' with 'perm' but still the same error message.
This is my init.lua now:

function ya.readable_size(size)
	local units = { "B", "KB", "MB", "GB", "TB", "PB", "EB" }
	local i = 1
	while size > 1024.0 and i < #units do
		size = size / 1024.0
		i = i + 1
	end
	return string.format("%.f%s", size, units[i])
end

function Folder:linemode(area)
	local mode = cx.active.conf.linemode
	if mode == "none" then
		return {}
	end

	local lines = {}
	for _, f in ipairs(self:by_kind(self.CURRENT).window) do
		local spans = { ui.Span(" ") }
		if mode == "size" then
			local size = f:size()
			spans[#spans + 1] = ui.Span(size and ya.readable_size(size) or "")
		elseif mode == "mtime" then
			local time = f.cha.mtime
			local actualtime = os.time()
			local actualyear = os.date("%Y", actualtime)
			local size = f:size()
			local actualfileyear = os.date("%Y", time)
			if actualyear = actualfileyear
				spans[#spans + 1] = ui.Span(size and ya.readable_size(size) or "")
				spans[#spans + 1] = ui.Span(time and os.date("%b %d %Y", time // 1) or "")
			else
				spans[#spans + 1] = ui.Span(size and ya.readable_size(size) or "")
				spans[#spans + 1] = ui.Span(time and os.date(" %b %d %H:%M", time // 1) or "")
			end
		elseif mode == "perm" then
			spans[#spans + 1] = ui.Span(f.cha:perm() or "")
		end

		spans[#spans + 1] = ui.Span(" ")
		lines[#lines + 1] = ui.Line(spans)
	end
	return ui.Paragraph(area, lines):align(ui.Paragraph.RIGHT)
end


local old_linemode = Folder.linemode
function Folder:linemode(area, files)
  if cx.active.conf.linemode ~= "my-own" then
    return old_linemode(self, area)
  end

  local lines = {}
  local year = os.date("%Y")
  for _, f in ipairs(files) do
    local time = f.cha.mtime // 1
    if time and os.date("%Y", time) == year then
      time = os.date("%b %d  %Y", time)
    else
      time = time and os.date("%b %d %H:%M", time) or ""
    end

    local size = f:size()
    lines[#lines + 1] = ui.Line {
      ui.Span(" "),
      ui.Span(size and ya.readable_size(size):gsub(" ", "") or "-"),
      ui.Span(" "),
      ui.Span(time),
      ui.Span(" "),
    }
  end
  return ui.Paragraph(area, lines):align(ui.Paragraph.RIGHT)
end

I see. The error message originates from the following expression:

			if actualyear = actualfileyear

To fix it, you can make the following change:

                        local actualyear = os.date("%Y", actualtime)
                        local size = f:size()
                        local actualfileyear = os.date("%Y", time)
-                       if actualyear = actualfileyear
+                       if actualyear == actualfileyear then
                                spans[#spans + 1] = ui.Span(size and ya.readable_size(size) or "")
                                spans[#spans + 1] = ui.Span(time and os.date("%b %d %Y", time // 1) or "")
                        else

However, using this code will result in another error message.

The solution is the same as the one provided in the discussion you linked: #1288 (comment)

This means your init.lua should include something like this:

function ya.readable_size(size)
	local units = { "B", "KB", "MB", "GB", "TB", "PB", "EB" }
	local i = 1
	while size > 1024.0 and i < #units do
		size = size / 1024.0
		i = i + 1
	end
	return string.format("%.f%s", size, units[i])
end

function Linemode:custom()
	local year = os.date("%Y")
	local time = (self._file.cha.mtime or 0) // 1

	if time > 0 and os.date("%Y", time) == year then
		time = os.date("%b %d %H:%M", time)
	else
		time = time and os.date("%b %d  %Y", time) or ""
	end

	local size = self._file:size()
	return ui.Line(string.format(" %s %s ", size and ya.readable_size(size):gsub(" ", "") or "-", time))
end

If you want to display this custom linemode by default, ensure the following is added to your yazi.toml file:

[manager]
linemode = "custom"

To use it with a keymap, you can include it in your keymap.toml file, for example:

[[manager.prepend_keymap]]
on = ["m", "c"]
run = "linemode custom"
desc = "Linemode: custom"

Let me know if this works for you!

Thank you very much, Filipe! Now it works.
