Running Scheme, SML, and Haskell
Setting your path
We will be using the instructional linux
machines: ceylon, fiji, sumatra, and
tahiti. Implementations of the three languages (and some
others) are located in /cse/courses/misc_lang/linux.
To use the languages, you should add
/cse/courses/misc_lang/linux/mit-scheme/bin,
/cse/courses/misc_lang/linux/sml/bin,
and
/cse/courses/misc_lang/linux/hugs/bin
to your path (in your .cshrc file).
If you don't already have
a path, then the line to add is
set path = ($path
/cse/courses/misc_lang/linux/mit-scheme/bin
/cse/courses/misc_lang/linux/sml/bin
/cse/courses/misc_lang/linux/hugs/bin).
Running Scheme
You can run Scheme interactively by typing scheme in a shell.
To load a bunch of functions from a file myfile.scm
into the interpreter, type (load "myfile.scm") at the
interpreter
prompt.
Running SML
You can run SML interactively by typing sml in a shell.
To load a bunch of functions from a file myfile.sml
into the interpreter, type use "myfile.sml"; at the
interpreter prompt.
Running Haskell
You can run Haskell interactively by typing hugs in a shell.
Unlike the Scheme and SML implementations, hugs does not let you type
functions directly at the interpreter prompt -- you can only evaluate
expressions.
To load a bunch of functions from a file myfile.hs
into the interpreter, type :load "myfile.hs" at the
interpreter prompt.
Don't like Linux?
The /cse/courses/misc_lang/ directory has implementations
of these languages for several operating systems other than linux.
You can download and install MIT
Scheme yourself.
You can download and install SML yourself.
You can download and install Hugs yourself.
