Scsh (a Scheme shell) is computer software, a type of shell for an operating system. It is a Portable Operating System Interface (POSIX) application programming interface (API) layered on the programming language Scheme, in a manner to make the most of Scheme's ability for scripting. Scsh is limited to 32-bit platforms but there is a development version against the latest Scheme 48 that works in 64-bit mode.[1] It is free and open-source software released under the BSD-3-Clause license.

Features

[edit]

Scsh includes these notable features:

Example

[edit]
#!/usr/local/bin/scsh -s
!#

(define (executables dir)
  (with-cwd dir
    (filter file-executable? (directory-files dir #t))))
(define (writeln x) (display x) (newline))

(for-each writeln
  (append-map executables ((infix-splitter ":") (getenv "PATH"))))

"Acknowledgments"

[edit]

The reference manual for Scsh includes a spoof Acknowledgments section[2] written by Olin Shivers. It starts:

Who should I thank? My so-called "colleagues", who laugh at me behind my back, all the while becoming famous on my work? My worthless graduate students, whose computer skills appear to be limited to downloading bitmaps off of netnews? My parents, who are still waiting for me to quit "fooling around with computers," go to med school, and become a radiologist? My department chairman, a manager who gives one new insight into and sympathy for disgruntled postal workers?

and concludes with:

Oh, yes, the acknowledgements. I think not. I did it. I did it all, by myself.
