http_require

Idea

The idea is very simple: test.rb:

# this will download bar.rb and eval its content.
require "http://foo.com/bar.rb"

If a remote file (or one of its local dependencies) requires something that can't be found locally, it will try to find it remotely from the same location as the parent.

Example

http://example.com/test/foo.rb:

# this will load "http://example.com/test/foo/bar.rb"
# if "foo/bar" is not available locally
require "foo/bar"

stacktrace

http_require properly sets filename on eval so that the file's uri appears in the stacktrace:

foo.rb:

puts :foo
require 'bar'
def foo
  bar
end

bar.rb

puts :bar
def bar
  raise
end

$ irb
>> require 'http_require'
=> true
>> require 'http://localhost:2000/foo.rb'
foo
bar
=> nil
>> foo
RuntimeError:
    from http://localhost:2000/bar.rb:3:in `bar'
    from http://localhost:2000/foo.rb:5:in `foo'
    from (irb):3
