a math library

[glycerine]

Starlark seem mighty terrific. I just have a minor query about doing some math.

In starlark-go, how would one raise n to the m-th power?

In Go, I would call math.Pow(n, m). In Python, math.pow(n, m).

Another way of asking: is there a way to get at the math library from Go perhaps?

[glycerine]

addressed deeply by #79, where import of the standard libraries such as "math" is enabled.

We do need a way to do exponentiation. We could define the ** operator, but we would still need a math library similar to that of Python and/or Go, in which case ** is redundant, and though it may be convenient in Python, I suspect numeric work in Starlark will be relatively uncommon.

@glycerine If there's any interest, we maintain a suite of library packages (including math) here: https://github.com/qri-io/starlib, I'd be happy to help make that work for your use case

[alandonovan]

Neat! The math and time packages in particular would be nice additions to go.starlark.net/lib, if that works for you.

[b5]

Absolutely! I'll try to put a PR together this weekend that includes your review comments. I'd love to see this code in go.starlark.net/lib 😄.

Hello @b5 any progress on said PR?

I'm quite interested in your math, time and re modules as well :)

[essobedo]

@b5 Ready for this one 😄 ?

[b5]

lol if you are, I guess so! But first we should check if our PR will be accepted. @brandjon would you accept a math library PR from us, and if so who's the right person to tag for review?

[adonovan]

I'd be happy to review it, and I will try to be a little more responsive this time. ;-)

[b5]

sounds great! I'll open the PR to get the conversation going. IIRC @dustmop from our team wrote the initial library, and is a much better pythonist than myself. @essobedo it'd be great to have you play a similar role this go-round if you're up for it 😄

[essobedo]

@b5 with pleasure, I'll do my best 😄 since I'm still learning Go (I'm rather a Java developer) and I like it

[brandjon]

Thanks for taking this review on Alan.
