Scsh is a POSIX API layered on top of the Scheme programming language in a manner to make the most of Scheme's capability for scripting. It is limited to 32-bit platforms but there is a development version against the latest scheme48 that works in 64-bit mode.
Scsh includes these notable features:
- Library support for list, character, and string manipulations;
- Regular expressions manipulation support using scheme regular expressions, a little languages approach to the capabilities;
- Strong networking support;
- High-level support for awk like scripts, integrated into the language as macros;
- Abstractions supporting pseudo terminals;
- A shell language, modeled using quasi-quotation.
#!/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"))))
- 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.
