Creating Your First Go Project
As we have already covered the basics of Golang in our golang tutorial, let’s see how to create your first Go project with simple and easy-to-follow steps.
Open File menu and create a new Go Project as shown below :
Enter the name of the project and choose your workspace location.
After creating project your IDE screen will appear like this –
You have to create your folders and .go files in src folder only.
Now right click on src folder→ New→ Folder
Then right click on the main (folder created by you) folder→ New Go File
Here Enter your go file name with .go extension and choose the Command Source file option. The first option will create empty main functions and Simple Web Server option creates Simple Web Application.
Create Go file in the src/main folder of your project with extension .go
The folders like github.com, golang.org and other ones will be created as you download the dependencies.
Here you can write your code. For example –
Now for executing this program you need to build the project. So double click on the build option as shown below –
It will build like this and generates main.exe binary file in bin package.
Sometimes while building a project, you will face building errors like –
So check the message and identify which package is missing and then go to command prompt and type the >go get <github_url_packageName>
So for above messages, enter below commands →
go get -u github.com/alecthomas/gometalinter
go get -u github.com/stretchr/testify
go get golang.org/x/net/html
go get golang.org/x/text/encoding
go get golang.org/x/text/encoding/charmap
go get golang.org/x/text/encoding/htmlindex
go get golang.org/x/text/transform
go get golang.org/x/crypto/ssh/terminal
Now again try to rebuild it and it will create main.exe file in your bin folder of project file for example – Main.exe
Now for running your project –
Right click on your project→ Select Run As→ Run Configurations
Then select the project and package to build i.e. main
Select your project by clicking on Browse
Now, select the package to build
And then click on Run so that your Go program will execute
We can also execute the go program by going to the main pkg of project and type –
> go run main.go command
Again if you need more programs inside, follow the same procedure
