The spec does preclude that since there must be a `package main`. https://golang.org/ref/spec#Program_execution On Wed, 2017-10-25 at 05:02 +, Alex Buchanan wrote: > Interesting, thanks. Let me try to clarify my idea with some simple > code: > > // file lives at github.com/buchanae/foobar/fo

Interesting, thanks. Let me try to clarify my idea with some simple code: // file lives at github.com/buchanae/foobar/foobar.go package foobar func Foobar() string { return "foobar" } func main() { print(Foobar()) } This file exports both a function to be used as a library, and a main funct

Re: [go-nuts] import a "main" package

Is there documentation (or other) explaining why the main package must have name "main" and may not be imported? Is this an important simplification for the compiler? I'd love it if a single "go get " represented both my library root and my command line binary. On Sunday, September 24, 2017 at

Re: [go-nuts] Re: Pure Golang Android Service

The manifest can specify hooks for Service implementations, such as to start on-boot, but the platform still requires the implementation of the Service class. One could write a generic NativeService implementation for easy reuse and launching of native processes, but otherwise nothing has changed w

Has anything here changed? Given that Go mobile apps are really just Go apps, I wonder if a service could be made by simply having the correct manifest... On Monday, November 23, 2015 at 10:45:53 PM UTC-5, Regan Laitila wrote: > > Hello Everyone, > > I'm curious if it is possible to write an all

Thank you all for all your help! My takeaway from this is that, generally, it is not beneficial to check the error from ResponseWriter.Write() since usually no action can be taken. On Monday, October 23, 2017 at 12:56:04 AM UTC-5, Tamás Gulácsi wrote: > > In thw concrete case, ResponseWriter.Wri

Thanks Gabriel; I will check out the tools and do some tests. Also thanks for the info Ian. I didn't think a .so would save much in the long run, but I want to be able to throw some numbers at my boss if I pitch go as a C++ alternative for a project. On Tue, Oct 24, 2017, 7:47 AM Ian Lance Taylor
