[ANN] gijit, an interactive Go environment, backed by LuaJIT

[Jason Aten]

I've long wanted an interactive Go for data analysis. One that could also call native Go libraries and C libraries easily.

I got tired of waiting for one. So I built gijit.  LuaJIT, the backend, can even inline calls into native C libs.

https://github.com/gijit/gi

gijit v0.9.4 feature summary:

• interactively code in Go. Just-in-time for Valentine's Day, a Go REPL that is not based on re-compiling everything after every line.

• the ability to import binary Go packages. Call into native Go code from the REPL.

• use Go as a calculator. Just start the line with '='.

• structs, interfaces, pointers, defer are all available.

• current limitation: no go/select/chan implementation.

• portable. Doesn't depend on Go's linux-only plugin system. We run on OSX and Linux.

Theoretically, gijit should build on Windows, since both Go and LuaJIT are regularly used on Windows. I don't have resources to confirm this and figure out the right build flags. (See https://github.com/gijit/gi/issues/18 if you do.)

Enjoy,

Jason

Looks interesting! It’s great to see all of the efforts developing around interactive Go.
