How to separate a raw Git file into tabs?

I’m trying to figure out how to download a raw file on Github like this

local url = "https://raw.githubusercontent.com/Evan03Davis/Baloon-Popper/master/Installer"

function success(data)
    saveProjectTab("Main", data)
    close()
end

function fail(error)
    print("Can't connect to given URL")
    assert(error)
end

http.request(url, success, fail)

This works but it doesn’t separate it into the tabs.
Any help?
Thanks.

Why are you trying to install an installer?

Never mind, sorry
