Hey guys,
I was reading the recent thread between Aaron and Sam, and noticed Aaron
asked a question about why you'd want to implement a parser for SymPy. This
is something I've thought about a lot, since I built two projects that
implement parsers for calculating languages (calculize.com and encalc.com --
Encalc uses SymPy, in fact). I'm thinking of starting a new project,
tentatively called SymPyScript, that would implement a parser from a new
language "SymPyScript" to Python + SymPy + perhaps other libraries.
What's the benefit? Well, for example, what if you could write this:
(3x^2 + ln(x))'
...and it'd compile to this:
x = Symbol("x")
diff(3 * x**2 + ln(x), x)
Or this:
x^2 - 2x === 3
...and it'd compile to this:
x = Symbol("x")
solve(x**2 - 3*x - 2, x)
Or more complicated things I haven't yet thought of.
Wouldn't that be cool? I think so. It'd be nice to have for a
workbook-style REPL. Just some food for thought, to get people thinking
about new ideas.
- Jeff
