CONTINUAL INTEGRATION

Problem scenario
You are running a Go program. You see this message about "command-line-arguments":

non-name m1["foo"] on left side of :=

What should you do?

Possible Solution
Can you try to use "=" instead of ":="? This may fix your problem.

The := is a variable declaration and an assignment. If your map has been declared, individual values in it should be assigned with an "=" (equals sign).

Problem scenario
You are trying to learn to program in Go. How do you use a function?

Solution
Prerequisite
This assumes that you have installed Golang; if you need assistance with this, see this posting.

Procedures
1. Create a file called b.go with this as the content:

package main

import "fmt"

// ContintFunction will display a message
func ContintFunction() {
        fmt.Println("Hello from Continual Integration")
}

func main() {
        ContintFunction()
}

2. Run it like this: go run b.go

Problem scenario
You want to create bytecode using Golang. What do you do.

Solution
Prerequisite
Install Golang. If you need assistance, see this posting.

Procedures
Create a Go script that you can run with go run nameOfProgram.go
Run this: go build nameOfProgram.go
Run this: ./nameOfProgram

Problem scenario
Lists have a fixed length number of discrete items. You want the items in the list to be strings. How do you create a list of strings in Golang?

Solution
1. Use this program called animal.go:

package main

import "fmt"

func main() {
  var x [10]string
  x[0] = "dog"
  x[1] = "cat"
  x[2] = "hamster"
  x[3] = "rabbit"
  x[4] = "chicken"

  for i := 0; i < 5; i++ {
    fmt.Println(x[i])
  }
}

2. Run it like this: go run animal.go
