There is no escaping mechanism built in to os.Expand. One workaround would be to define an environment variable containing a dollar sign: https://play.golang.org/p/InJx2_EWB2 Another is to substitute an unused character or string and replace it after expansion: https://play.golang.org/p/j8Oa3dgdoH

Re: [go-nuts] Golang package documentation: missing methods? Are they missing on purpose?

That's just how interfaces are rendered in Godoc. (Compare, for example, io.Reader.) Concrete types (e.g., reflect.Value) have their method docs listed explicitly. Perhaps it looks strange because reflect.Type is an extremely large interface. Most interfaces in the stdlib have about 1-3 methods.

Hi all, I want to know why Golang do not have type-embeded consts or variables (Just like static values and method build-in classes in object oriented languages like C++) This feature helps us define type-shared valuse, and do not increase size of instanced objects. Unfortunately Golang do not h

This code is not using the API correctly, and the implementation notices this and complains, as it should. Whether it worked in 1.2.1 is unknown to me, but the Split functions are meant to be called only from the Scan method, and are exported for the sole purpose of initializing the Scanner. Your

Hi, It seems you assume that the server sends a single response for each message received. But don't forget that WebSocket is fully duplex and the server can send multiple messages at any time while you wait for input. Regards, Kwang Yul Seo On Sun, Sep 25, 2016 at 10:02 PM, mhhcbon wrote: >

The interface for One.Item is expecting a One.Item as an argument to its Less() method. By embedding it in Two.Item, that shouldn't change that correct? So the resulting public interface for Two.Item *after embedding* One.Item is technically. type Item interface { Less(One.Item) bool Le
