Numscrypt 0.0.18

Purely experimental attempt to port a microscopic part of NumPy to Transcrypt using JS typed arrays

Numscrypt?

Numscrypt is an experimental attempt to port a microscopically Small Sane Subset of NumPy to Transcrypt using JS typed arrays. While some attention is paid to speed, e.g. by using inline JavaScript for inner loops, that is currently not the main focus.

Parts of the code can later be replaced by things like asm.js and simd.js, or, better even, GPGPU code. There’s not yet a clear winner in this area. This implementation is usable as a skeleton to try out those new technologies in parts of the code where speed matters most.

It may seem attractive to compile everything from C++ to asm.js, but the downloads would become very bulky and the readability approaching zero. Or wouldn’t it? Forking and experimenting highly encouraged!!

As with Transcrypt, the eventual goal is not to completely copy a desktop programming environment. Rather a lean and mean subset is sought that can still be very useful, e.g. for science demo’s in the browser.
