Functions ¶
func Invoke ¶
func Invoke(fn interface{}) error
Example ¶
package main
import (
"fmt"
"log"
"github.com/kmrtftech/tg-framework/pkg/typapp"
)
func main() {
typapp.Reset()
typapp.Provide("", func() string { return "world" })
err := typapp.Invoke(func(text string) {
fmt.Printf("hello %s\n", text)
})
if err != nil {
log.Fatal(err)
}
}
Output: hello world
Example (Second) ¶
package main
import (
"fmt"
"log"
"github.com/kmrtftech/tg-framework/pkg/typapp"
"go.uber.org/dig"
)
func main() {
typapp.Reset()
typapp.Provide("t1", func() string { return "hello" }) // provide same type
typapp.Provide("t2", func() string { return "world" }) // provide same type
type param struct {
dig.In
Text1 string `name:"t1"`
Text2 string `name:"t2"`
}
printHello := func(p param) {
fmt.Printf("%s %s\n", p.Text1, p.Text2)
}
if err := typapp.Invoke(printHello); err != nil {
log.Fatal(err)
}
}
Output: hello world
func SetConstructors ¶
func SetConstructors(c []*Constructor)
func SetContainer ¶
func StartApp ¶
StartApp start the service with gracefully stop
Example ¶
package main
import (
"fmt"
"log"
"github.com/kmrtftech/tg-framework/pkg/typapp"
)
func main() {
typapp.Reset() // make sure constructor and container is empty (optional)
typapp.Provide("", func() string { return "world" })
startFn := func(text string) { fmt.Printf("hello %s\n", text) }
stopFn := func() { fmt.Println("bye2") }
if err := typapp.StartApp(startFn, stopFn); err != nil {
log.Fatal(err)
}
}
Output: hello world bye2
Types ¶
type Constructor ¶
type Constructor struct {
Name string
Fn interface{}
}
Constructor details
func Constructors ¶
func Constructors() []*Constructor
type CtorAnnot ¶
type CtorAnnot struct{}
CtorAnnot handle @ctor annotation e.g. `@ctor (name:"NAME")`
func (*CtorAnnot) AnnotationName ¶
