Plugin creation: How do you loop over all selected files

[thepsauce]

I have answered my own question by looking through the github page and the website. The solution is at the bottom..

Hello, I'm trying to make a plugin in yazi using lua. I want to get input from the user and loop over all selected files (marked with space or any other method). This was my attempt:

local M = {}

function M:entry()
    local value, event = ya.input {
	    title = "Tag file",
	    position = { "center", w = 50 },
    }
    if event == 1 then
        for idx, url in pairs(cx.yanked) do
            ya.notify {
                title = "you",
                content = url.name,
                timeout = 2,
            }
        end
    end
end

return M

But it can't run the loop after if event == 1 then, it gives this error:

Micro plugin failed:
runtime error: [string "/usr/src/debug/yazi/yazi-0.2.5/yazi-plugin/sr..."]:9: attempt to index a nil value (global 'cx')
stack traceback:
	[string "/usr/src/debug/yazi/yazi-0.2.5/yazi-plugin/sr..."]:9: in function <[string "/usr/src/debug/yazi/yazi-0.2.5/yazi-plugin/sr..."]:3>

What I actually want to do is for each selected file create a symlink using ln -s <file> <name> when a key is pressed.

Edit: I got one step further!

local M = {}

local tag_files = ya.sync(function(state)
	local h = cx.active.current.hovered
    if h then
        ya.notify {
            title = "tagged",
            content = tostring(h.url),
            timeout = 2,
        }
    end
    for idx, url in pairs(cx.yanked) do
        ya.notify {
            title = "tagged",
            content = tostring(url),
            timeout = 2,
        }
    end
end)

function M:entry()
    local value, event = ya.input {
	    title = "Tag file",
	    position = { "center", w = 50 },
    }
    if event == 1 then
        tag_files()
    end
end

return M

This now works for the currently hovered file but not the selected files, but now I noticed that cx.yanked is probably not the selected files but actually the yanked files.. so my question remains.

Edit2: I figured it out after viewing this, Folder.CURRENT just worked instead of PREVIEW.

local folder = Folder:by_kind(Folder.CURRENT)
if not folder then
    return
end

for i, f in ipairs(folder.window) do
    local marker = File:marker(f)
    if marker ~= 0 then
        ya.notify {
            title = "tagged",
            content = tostring(f.url),
            timeout = 2,
        }
    end
end

It is not recommended to use ipairs(folder.window) since it needs to iterate over all files, which is inefficient and can only get the visible files in the window.

• If you want to access the selected file(s), use cx.active.selected
• If you want to access the yanked file(s), use cx.yanked

They both need to be used in a sync context.

Great, thank you! This worked:

for i, f in pairs(cx.active.selected) do
    tag_file(f:name(), tags)
end
