Re: [go-nuts] [Proposal] Std Lib Logging Abstraction

let's assume you use a package that logs with std "log" package and my app uses something else let's say logrus. What would the logging result be? Would it not be inconsistent? On Monday, February 13, 2017 at 9:47:46 AM UTC+2, Jan Mercl wrote: > > On Mon, Feb 13, 2017 at 8:44 AM Sotirios Mantziar

[go-nuts] [Proposal] Std Lib Logging Abstraction

Hi, i was wondering if the std lib should implement a logging abstraction so that every lib developer can abstract away logging and let the final lib user provide the implementation it needs. The reason for this is that like everybody else i use a lot of open source and many of them use std "l

You can probably assume by default that any open source project out there with open issues welcomes your help. :) On GitHub, you can list the most starred repos. These are projects that have been around for a long time and probably are fairly mature in welcoming new contributors. Definitely bro

Thanks to all who answered; I got explanation I needed. @"Michael Jones": yes, your solution also works - "i := i" overshadows the i defined as part of the for-loop and that was also explained in one of the Go-blogs. Anyways, as I have already acknowledged earlier, this was an RTFM moment for me.

Take a look at the reflect package, or if you know that the only internal maps will be of type map[string]interface{} you can use type assertion to determine if the element is a map or some other type. On Sun, Feb 12, 2017 at 7:53 AM, wrote: > I would like to write a function which, given: > >
