[go-nuts] Re: building an exe that will embed import in the .exe

Zdravo Zlatko, I thought that too but after building an .exe and copying/moving it to another comp, it behaved as if it worked but did not generate a file, so i thought the imported package was not embedded in the .exe So after your response i looked more carefully in the code and i noticed a

[go-nuts] Status of golang.org/x/text/currency (github.com/golang/text)?

There is no issue section in this repository to start a discussion. I would like to ask about the status of currency package. There seems to be plan for further development according to the comments (https://github.com/golang/text/blob/master/currency/format.go#L26). Any update on this? I

Certainly possible. You can put the whitelisted IPS in a map and use that to filter the incoming requests. On Thursday, August 4, 2016 at 10:17:37 AM UTC-4, Naveen Shivegowda wrote: > > Is it possible to make http servers listen only on a few source ip's and > request from any other source

This is excellent, really helpful. The -help flag only mentions testing and casual searching only again pops up with info on more testing, I couldn't see anything on actually using it for running a generic binary. Perhaps it would be worth adding this to the documentation? + things like not

[go-nuts] Re: how to apply netutil.LimitListener() to ListenAndServeTLS()'s listener? how to fetch ListenAndServeTLS()'s listener?

Your research revealed the essential lines from ListenAndServeTLS that basically say: 1. create a tls listener 2. have the server serve using that listener The LimitListener example follows this same pattern, just with net.Listener instead of a tls.Listener. A careful reading reveals that

[go-nuts] Re: how to apply netutil.LimitListener() to ListenAndServeTLS()'s listener? how to fetch ListenAndServeTLS()'s listener?

The issue here in essence is that an http.Server doesn't store a new.Listener to expose, it only operates on one provided to the Serve method. Without changing the api, there's no way to expose a listener in an http.Server in a way that doesn't interfere with the other methods. However, I

Re: [go-nuts] building an exe that will embed import in the .exe

Hello, When you compile go program, all your source and source from all imported packages is compiled together in the same binary (.exe). You don't need to worry about it. That's actually one of the go strengths, no dll hell. On 03.08.2016 07:57, ov35...@gmail.com wrote: Hi, i have a

Re: [go-nuts] Re: Who wants to use Go to process your camera's raw files?

As one would want a clean Go library, I think this library should be implemented from scratch in Go - there is also a better chance to get a really good performing library, if it is designed in Go and not in C. One obvious thing is, to do all heavy computations in parallel via goroutines.
