Pure, the successor to Q

[btiffin]

Dr. Albert Graef from the University of Mainz in Germany has developed a pretty cool programming language with Pure.

http://en.wikipedia.org/wiki/Pure_(programming_language)

The first 1000 Fibonacci numbers;

code:

extern int puts(char*); do (puts.str) (take 1000 (fibs 0L 1L)) with fibs a b = a : fibs b (a+b) & end;

last line of that one being

26863810024485359386146727202142923967616609318986952340123175997617981700247881689338369654483356564191827856161443356312976673642210350324634850410377680367334151172899169723197082763985615764450078474174626L

And I guess it's not just the language, it's the interactive environment that makes it fun(ner) to explore.

Nice built in help, source reflection etc.

And, well thought out integration with C, so it went into OpenCOBOL on the first try.

Can you see it now? A crusty old COBOL coder, cranking out FP routines and showing auditors lazy evaluated bindings to term rewrites that include open ended infinities? For banking?

I had issues with a Fedora 18 install, Pure wanting LLVM 3.2, and tripping on 3.3, but a few files from a Fedora 17 setup, and good to go for exploring.

Have you tried haskell? The GHCI is a blast to play with, and it supposedly has really good C integration as well.

haskell compiles to C code before compiling down completely so it is extremely fast. My prof used it as pseudo code last year and there were a bunch of really cool things. Plus its a functional language which can be lots of fun once you get used to it.

mirhagk; Pure uses Haskell for its pure-gen package. pure-gen is a header file binding generator (for things like pure-gtk). But I can't say I have more than 15 minutes in with ghc and the toolset.

crossley7; Yeah, I'm pretty sure Pure got a lot of ideas from Haskell, the interpreter running C translations and compiles as you type commands. Pretty cool for how speedy it feels.

Cheers
