Passing itemlinks to slash commands

I am wanting to pass an itemlink to a slash command such as

Code:

/fs add <Linen Cloth>

but when I use GetItemInfo() BugSack returns "Usage: GetItemInfo(ItemID|"name"|"itemLink")

Presently I am add

Code:

SLASH_SERVANT1 = "/fs"

SlashCmdList.SERVANT = function(func, arg1)

        local infoType, itemID, itemLink = GetItemInfo(arg1)

end

What am I doing wrong here?

arg1 is the full command. Skip the 'add'.

The "add" will be needed as I am adding to table.
Func does return add when printed, so that's not a problem.

To expand further on Rilgamon's post, slash commands pass everything after the actual command into only the first variable. arg1 is nil here.

In your function,

Lua Code:

func == "add <Linen Cloth>"

and

Lua Code:

arg1 == nil

which means you are doing

Lua Code:

GetItemInfo(nil)

which causes the error.

If you want add/remove commands, you have to "take apart" the first variable. One common method is

Lua Code:

SlashCmdList.SERVANT = function(input)
local command, link = strsplit(" ", input)

where

Lua Code:

command == "add"

and

Lua Code:

link == "<Linen Cloth>"

Presently I am using

Code:

SLASH_SERVANT1 = "/fs"

SlashCmdList.SERVANT = function(input)

        local command, link = strsplit(" ", input)



        print(command)

        print(link)

end

command = add
link = not a thing nor BugSack error

Try:

Code:

SLASH_SERVANT1 = "/fs"

SlashCmdList.SERVANT = function(input)

        local command, link = input:match("^(%w+)%s+(.+)$")



        print(command)

        print(link)

end

If command will never contain numbers then you can change %w+ to %a+ for just letters (as outlined here).

Mkay, that got me on track.

You were likely linking an item that had a space in it, when testing with Kanegasi's code.

strsplit accepts an optional 3rd argument that defines how many pieces to make.

You can still use Kanegasi's simpler method like this.

Lua Code:

local command, link = strsplit(" ", input, 2)
