Scsh is a Unix shell in that is has significant syntax extensions to
|
|
|
|
|
make writing Unix shell scripts easy (constructing pipelines, setting
|
|
|
|
|
I/O redirection, conditional execution etc.). It also offers access to
|
|
|
|
|
lower-level functionality like all Posix system calls, TCP/IP sockets
|
|
|
|
|
and a full-featured regular expression library. This is embedded into
|
|
|
|
|
a general-purpose programming language with real data types,
|
|
|
|
|
extensive, syntactically clean control constructs and "real" quoting
|
|
|
|
|
rules.

Scsh is also a full implementation of R4RS Scheme with some
|
|
|
|
|
non-standard behavior (required for scripting). As a result, a wide

|
variety of existing Scheme code can be used.

The underlying Scheme implementation is a virtual machine for compact
|
|
|
|
|
byte code.
