Re: [go-nuts] plugin - How to open and lookup for interface implementation

AFAIK it's a design decision that a plugin cannot be loaded twice. Protect it with a sync.Once, if you can't avoid calling the loader twice. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group. To unsubscribe from this group and stop receiving emails

[go-nuts] Rune-by-rune through a stream

Just a thought experiment, but what's the idiomatic way to read rune-by-rune from a stream that represents a string of infinite length? The stream itself can be from std.In or continually generated by a function. Would I use bufio.Scanner or bufio.Reader? I suppose its also possible to use a

[go-nuts] Re: With GO - Can I say Procedural is better than OO?

Go also support first-class function which is an idea brought from functional programming. Anyhow, in my opinion, you shouldn't be too dogmatic about a particular paradigm. There are cases that can be solved elegantly using a particular paradigm and there are cases that will lead to further

I started to play with this new plugin feature and I got some problems when I tried to load two different plugins one by one. If I have first plugin as it was describe in the original post and new one: *Interface:* package processor type Processor interface { Process(text string) } *And

It's quite efficient to have a lot of goroutines. That's how I update the feeds in my aggregator. Though your network interface might not like it if you try to initiate thousands of connections at the same time. On Friday, November 4, 2016 at 11:14:24 PM UTC+2, Marwan abdel moneim wrote: > > i

I should also state that in this example you could of course just use MarshalIndent, the point was to show that you could do it manually if you need more customized formatting. On Sat, Nov 5, 2016 at 11:13 AM, Sam Whited wrote: > On Sat, Nov 5, 2016 at 10:57 AM, Tong Sun

[go-nuts] Concurrently read map entries into a channel

Hey, I have a scenario where I need to iterate over (as many as possible) map entries and send them into a channel. The operation on the other end of the channel can take a long time, so sends on the channel may block for a long time. The map is protected by an RWMutex. The map is also rather

Hi, So I have the following: https://play.golang.org/p/dcuhh40DFZ Yet I believe it exposes the following issues: 1. If sendWork is at line 54, it's possible that doWrites will hit line 79, falsely reporting a timeout case due to timing issues. Correct? 2. In case of a real timeout (where the
