A surprisingly powerful Unix shell
Description
Oh is a Unix shell. If you've used other Unix shells, oh should feel
familiar.
Where oh diverges from traditional Unix shells is in its programming
language features.
At its core, oh is a heavily modified dialect of the Scheme programming
language, complete with first-class continuations and proper tail
recursion. Like early Scheme implementations, oh exposes environments
as first-class values. Oh extends environments to allow both public and
private members and uses these extended first-class environments as the
basis for its prototype-based object system.
Written in Go, oh is also a concurrent programming language. It exposes
channels, in addition to pipes, as first-class values. As oh uses the
same syntax for code and data, channels and pipes can, in many cases, be
used interchangeably. This homoiconic nature also allows oh to support
fexprs which, in turn, allow oh to be easily extended. In fact, much of
oh is written in oh.1
