I'd like to write a program that uses a Mathematica-like syntax. Not a

100% clone, but as close to Mathematica input as reasonably practical.

Can anyone suggest a suitable front end parser? I was thinking of

using LLVM for the back end.

Here's a description of the syntax

http://reference.wolfram.com/mathematica/guide/Syntax.html

http://reference.wolfram.com/mathematica/tutorial/TheSyntaxOfTheMathematicaLanguage.html

Things to note in particular is that whitespace can often mean

multiplication. i.e.

In[1]:= 12.1 2

Out[1]= 24.2

Mathematica supports many programming styles - procedule, functional

and rule-based programming

A Lisp to Mathematica translator was written by Prof Fateman

In the paper Fateman says the language appears to be ad-hoc, so he had

limited success with a common parser and used a hand-written one. But

I'm not entirely convinced of his objectivity - he tends to mock the

creators of Mathematica - his program is called MockMMA. He was one of

the creators of a computer algebra system Maxima, which he always

compares favorably to Mathematica, though few others do,

I've never written a compiler, beyond noddy calculators in

introductory books, so I suspect this language is not an ideal one to

learn with. But I'd be interested in what, if any tools would be

capable of handling such a complex language,

Dave
