Getting filename length

Something that has stumped me for a while, how do you get the length of a filename if you pull it in as an icon.

Say:

var/icon/I = input("Get the icon") as icon|null


You can get the name of the file by just using << "[I]" and using length gives you the length of file. name also isn't a varible.

Thanks for the help in advance.

OK, I havn't tested this or anything, but try...
length("[I.icon]")

/icon happens to have an 'icon' variable.

Thanks, I'll try it when I get home and post an update.

Heh, nope.

runtime error: Cannot read 'H2.dmi'.icon

(makes sense)
from

mob/verb/Test()
    var/icon/I = input("Insert the icon") as icon|null
    usr << length("[I.icon]")

/icon happens to have an 'icon' variable.

But he was asking about an icon file, not an /icon datum. As it is, /icon.icon will not give you a file length because it's an internal structure.

However, if the icon was selected as a file, length(iconfile) should work. If not, then try length(file("[iconfile]")), which should convert everything to the proper format.

I tried those ways and ended up getting the size of the data. I think I didn't say what I needed clearly enough, sorry.

If someone selects a file called "Guy.dmi" I want it to show the length of the file name, being 7.

mob/verb
    File_Size(F as file)
    usr << "[F] is [length(F)] bytes"

Here is your code. this will let you pick the file on your computer and then tell you the size of it in bytes.

Doing length("[I]") should work.

Oh yeah, that's easy.

length("[iconfile]")


Note this will only work for an actual file, not an /icon.
