Get file name from URL using Lua

How do I get the file name from a URL using Lua string manipulations.

I have this url

https://thisisarandomsite.com/some_dir/src/blah/blah/7fd34a0945b036685bbd6cc2583a5c30.jpg

And I want to get the 7fd34a0945b036685bbd6cc2583a5c30.jpg, it can be a random site so the site name is not static.

Solution

  • Try this:

    local str = "https://thisisarandomsite.com/some_dir/src/blah/blah/7fd34a0945b036685bbd6cc2583a5c30.jpg"
local name = str:match( "([^/]+)$" )

    You can customise the match pattern from this guide.
