Clean 2.1.1 is now available for Windows, Mac OS X, Linux (Intel)
and Solaris (Sparc) at
<http://www.cs.ru.nl/~clean/Download/main/main.htm>.
New in 2.1.1 (compared to version 2.1.0):
- New libraries: GAST, GEC, Hilde and Parsers (for Windows).
- Improved redirected standard input/output files.
- clean functions using integers and tuples can be called from c
using foreign export, for example:
implementation module f;
import StdEnv;
foreign export f;
f :: !Int !Int -> Int;
f a b = sum [a..b];
call_f :: !Int !Int -> Int;
call_f a b = code {
ccall "GII:I"
};
Start = call_f 1 20;
definition module f;
f :: !Int !Int -> Int;
will call the function f using the c calling convention. Functions
exported using foreign export can only be called from c if
the c code is called from Clean using a ccall with a 'G' as first
character of the string. htoclean does not yet generate these 'G's.
- let can be used after a generator in comprehensions (without in),
for example:
[ s \\ n <- [1..10],
let s = n*n
| s>=40
]
- Code generator optimizations:
- optimized array indices that consist of an add or subtract
of a value and a small constant, for example: a.[i+1],
a.[1+i] or a[i-1].
- branch optimization that improves the speed of small loops.
- faster bitnot, ~ for integers and abs for reals.
- small improvement in the register allocator for ia32.
- Bug fixes.
