This module implements (require (github ...)) syntax.
Example:
The user "soegaard" has a repository "this-and-that" on GitHub:
https://github.com/soegaard/this-and-that
The latest commit-id (read: version) is "faf74b7". The file "split-between.rkt" provides a function split-between.
> (require (github soegaard this-and-that master faf74b7 "split-between.rkt"))
[Downloading from GitHub.]
> (split-between (λ (x y) (not (= x y))) '(1 1 2 3 3 4 5 5))
'((1 1) (2) (3 3) (4) (5 5))
The form automatically downloads the latest version of the repository from GitHub. It is stored in a cache. The second time a given version is required it is not downloaded again.
It is possible to use head as the commit-id in order to get the latest version from GitHub. Using an explicit commit-id is faster though. When using head a http request to GitHub is needed to establish the commit-id of the head.
