Lispkit is a project mainly written in C and COMMON LISP, it's free.
A Lispkit implementation
This program is an implementation of the Lispkit described in the book "FUNCTIONAL PROGRAMMING: Application and Implementation", by Peter Henderson, ISBN 0-13-331579-7.
If you have a C compiler and make, like gcc and gmake, you can build the program with:
make
If compilation is successful, you can test lispkit - this will attempt some of the examples from table 12.1 and 12.2 in the book.
make test
To compile a lispkit program, where [filename] is the name of a file containing lispkit source code:
./lispkit compiler.ascii [filename]
To compile one of the examples, examples/square.lisp:
make examples/square.o
You should see some output like:
( 3 ( 1 ( 0 . 0 ) 1 ( 0 . 0 ) 17 5 ) 4 21 )
Then run it, with no second argument lispkit will read the input from stdin. Type a number e.g. 9, press enter, then ctrl-d, and the result will be printed to stdout:
./lispkit examples/square.o 9 81
