#golang #go #packages Custom Packages and Functions - A. Blank identifier - _ "underscore" B. Godoc - Utility to get package documentation about all the go packages C. Returning values from functions - User defined functions D. Custom packages Note:- Function names starts with lowercase alphabets will not be exported to use outside from a go program Function names started with uppercase letters are only can be used outside the go program or package 1. Set up GOPATH to the current working directory/ root of the package 2. Inside GOPATH directory create src/packagename ex:- GOPATH/src/hello - Hello is the name of the package 3. Create Package Hello (not a command) 4. Switch over to the GOPATH directory 5. Create a go program to import and use the custom package hello Source Code - blankdemo.go package main import ("fmt" _ "strings" ) func main(){ fmt.Println("Blank demo") } funcdemo.go - package main import "fmt" func main(){ show() //Call Function Show display("Calling display with argument") result:=add(10,20) fmt.Printf("The sum is %d\n",result) } func show(){ fmt.Println("Inside Show Function") } func display(message string){ fmt.Println(message) } func add(first int,second int)(int){ //Return values from the function sum:=first+second return sum } mathematics.go (create it inside GOPATH/src/mathematics/) - package mathematics func Add(a int,b int)(int){ return a+b } func Sub(a int,b int)(int){ return a-b } func Mul(a int,b int)(int){ return a*b } func Div(a int,b int)(int){ return a/b } calc.go (create it inside GOPATH) - package main import ("mathematics" "fmt" ) func main(){ a:=20 b:=10 fmt.Printf("The sum of %d and %d is %d \n",a,b,mathematics.Add(a,b)) fmt.Printf("The difference of %d and %d is %d\n",a,b,mathematics.Sub(a,b)) fmt.Printf("The product of %d and %d is %d\n",a,b,mathematics.Mul(a,b)) fmt.Printf("The division of %d and %d is %d\n",a,b,mathematics.Div(a,b)) }

Software Architecture in Golang: Measuring Instability as Software Package Metrics

18.06.2021

When building software, how can we measure Instability? Back in 2002, Robert Martin, colloquially known as "Uncle Bob", wrote a book called "Agile Software Development: Principles, Patterns, and Practices", this book included metrics to measure Software Packages. In this episode I will cover one of the metrics called: "Instability", which defines "the ratio of efferent coupling (Ce) to total coupling (Ce + Ca) such that I = Ce / (Ce + Ca). This metric is an indicator of the package's resilience to change. The range for this metric is 0 to 1, with I=0 indicating a completely stable package and I=1 indicating a completely unstable package." * "Afferent couplings (Ca) The number of classes in other packages that depend upon classes within the package is an indicator of the package's responsibility. Afferent couplings signal inward." * "Efferent couplings (Ce): The number of classes in other packages that the classes in a package depend upon is an indicator of the package's dependence on externalities. Efferent couplings signal outward." 🤍 - RELEVANT LINKS * Example code: 🤍 * Software Package Metrics tool for Go: 🤍 * Previous Episode: "Software Architecture in Golang: C4 Model for Diagraming and Documentation": 🤍 * "Learning Golang: Dependencies, Modules and How to manage Packages": 🤍 * Playlist "Software Architecture in Go/Golang": 🤍 * Playlist "Learning Golang": 🤍 * Playlist "Building Microservices in Go/Golang": 🤍 * Playlist "Golang Tools and Packages": 🤍 * Playlist "Testing in Go": 🤍 00:00 - Start 00:10 - How to Measure Instability in Software Packages? 00:48 - What is Software Coupling? 01:52 - Efferent Coupling and Afferent Coupling 04:46 - Demo using spm-go 10:25 - Conclusion - Who am I: Hello👋🏼!

In this video we are going to learn about getting and setting Environment Variables. These can be used to configure your application at runtime. We will look at what an environment variable is, how to read it from the system and from a .env file. We will touch on a system process and how it creates a fork and his it's own copy of the environment variables. More info on fork/exec and system process can be found here probably more than you need, but maybe enough to go down a rabbit hole: 🤍 🤍 🤍 If you wanna support my channel, you can buy me a coffee: ☕️ 🤍 Coffee make the code go!!! 💻 Programming Laptop 🤍 🎥 My Video Kit 🤍 🖥 Video Editing PC 🤍 All code found in this video will be at: 🤍 #golang #nerdcademy
