Re: [go-nuts] builtin function definitions

The linked spec is the the definitive language specification. I read it carefully a couple of time (cannot recommend it enough) and knew about type switches. The most common language implementation is go's default compiler gc. Which is the place to implement the language spec and type switches

I'm working on a dev tool for automatically reloading the server when you change a file. I'd like for the reload time to be as fast as possible. Are there any flags or environment variables that I can set to see where the time is being spent (compiling, linking etc.)? Also seeing what packages

[go-nuts] Error Handling in Go 2

Go can already pass/pipe the result of a function, which returns multiple values, to another function, which accepts the same values as arguments. A similar mechanism can be used for handling errors, by passing/pipe them to a special construct. Now, assume we have a function named funcCtx: fun

Go can already pass/pipe the result of a function, which returns multiple values, to another function, which accepts the same values as arguments. Now, assume we have a function named funcCtx: func funcCtx() (res int, err error) { // ... } Having that, these does not look that ugly: func

Re: [go-nuts] builtin function definitions

This is a special kind of switch called a type switch. You can read more about it in the language specification where its part of the intrinsic go syntax. https://golang.org/ref/spec#Switch_statements Because it is a special language construct you need to look at the compiler. You probably wan

[go-nuts] Re: my package not include in go modules

A Go module is a collection of packages. The packages are in a tree of directories (Go requires all files in one directory to be part of the same package), and there is a go.mod file at the root of the tree. Users import packages individually, not the whole module. go.mod documents the depend
