Well, I figured out the problem. Basically Go starting path for import is $HOME/go/src So I just needed to add myapp in front of the package names, that is, the import should be: import ( “log” “net/http” “myapp/common” “myapp/routers” )
The content inside the backticks are tags: A field declaration may be followed by an optional string literal tag, which becomes an attribute for all the fields in the corresponding field declaration. The tags are made visible through a reflection interface and take part in type identity for structs but are otherwise ignored. // A … Read more
The super (possibly over) simplified definition is just that << is used for “times 2” and >> is for “divided by 2” – and the number after it is how many times. So n << x is “n times 2, x times”. And y >> z is “y divided by 2, z times”. For example, … Read more
You can use reflect.DeepEqual, or you can implement your own function (which performance wise would be better than using reflection): http://play.golang.org/p/CPdfsYGNy_ m1 := map[string]int{ “a”:1, “b”:2, } m2 := map[string]int{ “a”:1, “b”:2, } fmt.Println(reflect.DeepEqual(m1, m2))
NO,but there are some other options to implement default value. There are some good blog posts on the subject, but here are some specific examples. Option 1: The caller chooses to use default values // Both parameters are optional, use empty string for default value func Concat1(a string, b int) string { if a == … Read more
package main import “fmt” func main() { var x float64 = 5.7 var y int = int(x) fmt.Println(y) // outputs “5” }
The function time.NewTicker makes a channel that sends a periodic message, and provides a way to stop it. Use it something like this (untested): ticker := time.NewTicker(5 * time.Second) quit := make(chan struct{}) go func() { for { select { case <- ticker.C: // do stuff case <- quit: ticker.Stop() return } } }() You … Read more
The time.Parse function does not do Unix timestamps. Instead you can use strconv.ParseInt to parse the string to int64 and create the timestamp with time.Unix: package main import ( “fmt” “time” “strconv” ) func main() { i, err := strconv.ParseInt(“1405544146”, 10, 64) if err != nil { panic(err) } tm := time.Unix(i, 0) fmt.Println(tm) } … Read more
Use the function Contains from the strings package. import ( “strings” ) strings.Contains(“something”, “some”) // true
You can use the new golang.org/x/tools/go/packages for this. This provides a programmatic interface for most of go list: package main import ( “fmt” “golang.org/x/tools/go/packages” ) func main() { pkgs, err := packages.Load(nil, “std”) if err != nil { panic(err) } fmt.Println(pkgs) // Output: [archive/tar archive/zip bufio bytes compress/bzip2 … ] } To get a isStandardPackage() … Read more
