Development Status

adcl is under active (?) development. As soon as sub-packages reach beta status (semi-stable) they will be listed here.

Example: Reading messages from connection

package main

import (
    "bufio"
    "fmt"
    "io"
    "strings"

    "github.com/seoester/adcl/protocol/message"
    "github.com/seoester/adcl/protocol/parser"
)

// streamContent is the content of a simulated connection with three messages.
// The last message is invalid (code is missing) and will result in an error.
const streamContent = `ISTA 144 Invalid\sparameter\svalue! TOqwertzu
BSTA SDFSDF 000 OK
CSTA
`

func main() {
    conn := strings.NewReader(streamContent)
    reader := bufio.NewReader(conn)

    p := parser.New(reader)

    for {
        mes, err := p.ReadMessage()
        if err == io.EOF {
            break
        } else if err != nil {
            fmt.Println("Error occurred:", err)
            continue
        }

        fmt.Printf("Received Message: %+v\n Content: %+v\n", mes, mes.Content)

        handle(&mes)
    }

    fmt.Println("End of stream.")
}

func handle(mes *message.Message) {
    switch mes.Command {
    case message.CommandSTA:
        cnt := mes.Content.(*message.STAContent)
        fmt.Printf("Processing status message with code %d\n", cnt.Code.Code())
    }
}
