Golang Commands

Overview

In this blog I am going to explain about basic go command and in depth knowledge about go commands will come after this series of basic go programming end.

fallowing topic will be explained in this blog :

primary commands
help topic

Commands

Go ahead open command prompt on type go and press Enter.

you can see all the commands and help topic that go provide.

Primary Commands

this all are primary commands that go provide. this all are self explanatory. we have "bug" command for bug report, "clean" to clean previous projects, "install" to install packages to project.mod command needs explanation. which we will discuss on the next blog.

but the command I want to talk about is doc. if we run ''go doc <package name>'' command

example "go doc json.decoder.decode" it will show the out put below.

go doc json.decoder.decode command out put

and if you run "go doc json.decoder" it will show the out put below.

and if you run "go doc json" it will show the out put below.

so what "go doc" command do is, it will go to the source code and show the documentation comment that has been written to help understand code and api.

for "go doc json.decoder.decode" comment it went to the json package and decoder object and decode method and displayed the documentation comments.

Additional Help Topic

if you need any help regarding the commands, just run "go help <topic name>" it will provide you with the necessary information to use that command. Advance knowledge about go command will be provided in an different series of blog.

But the standard way to use go is to create a project or you can call it a space where you will be putting your go code, on the other hand it is a work space, but in Go Lang we call it module. In Go Lang modules are the official way of organize go code. in this blog I am going to explain the way you create a model and first hello world with that project. Explanation To Module you need to run the command bellow go mod init <module name> If you can see I have named my module github.com/TahimFaisal/golang. the name of the module is called module initializer. this is the standard way of initialization. And for the go get command it will it will know where to go and get the mod if it cannot find the mod locally. Okay, soon after you ran the command you will get a file named go.mod in your working directory it will be having module initializer and the version of go your using. ...

Primitive data type of Golang

Overview In this blog I am going to talk about the date types and variables in go. and the topics bellow Declaring and initializing variables explicit initialization of variables implicit initialization of variables complex data type list of data type Pointer pointer operator dereferencing operator address of operator Constant Iota and constant expression Declaring and initializing variables there are 2 ways you can declarer and initialize a variable they are explicit initialization variables implicit initialization variables Explicit initialization of variables in this way you have to tell the compiler every thing you need to declare a variable. var i int i = 20 var j int = 3 fmt.Println(i,j) var f float32 = 32.233 fmt.Println(f) in this way we are explicitly telling what will be the input type for that variable. Implicit initialization of variables in this way of declaring a variable. we don't have ...
