Requirements: Python 3.x. Adder has been tested under Python 3.1
on Linux (x86 and ARM). It ought to work under Windows
(its only OS interaction is in file I/O, and it
uses os.path for pathname manipulation), but I don't
have a Windows box to test it on. I'll test it on Mac Real Soon
Now.
At this point, Adder isn't really packaged up; you run it from the
source tree. If the base directory of the tree is at
/foo/bar/baz/adder, add it to
your PYTHONPATH
PYTHONPATH = $PYTHONPATH:/foo/bar/baz/adder:/foo/bar/baz/adder/+modules+
(The +modules+ bit is so that Python can find
modules
written in Adder.)
To run an Adder program quux.+, do:
/foo/bar/baz/adder/adder.py quux.+
The adder.py program is also the REPL:
$ ./adder.py Loading prelude...done. > (define (fact n) (if (< n 2) 1 (* n (fact (- n 1)))) ) #> (fact 7) 5040 >
There are a few sample scripts in .../adder/samples,
and a few modules in .../adder/modules. You'll also
want to read the language spec.
