Most of the files in this directory are written in the S-Lang
language, which is the extension language of the editor. See
<http://www.s-lang.org> for more information about the
language.
Please note that much of the code in these files may not be
understandable to those with little exposure to S-Lang. Some of the
code has been written in such a way that it byte-compiles to as few
bytes as possible. For example, consider the go_down function which
is used as:
go_down (10); % Move down 10 lines
site.sl defines this function as:
define go_down() { () = down(); }
which makes it appear not to take any arguments as all. However, this
is equivalent to:
define go_down (n) { () = down (n); }
but the body of the latter version requires twice as many byte-codes.
The implemented version allows the argument passed to `go_down' to
stay on the stack to be picked up by the `down' function.
