Go Simple CLI Boilerplate

Simple boilerplate to create CLI applications with Go

How to use

With Docker

• Clone this repo and enter it

• Run docker build -t "mytag" .

• Run docker run -it --rm mytag hello

Without Docker

• Clone this repo and enter it

• Run go get ./...

• Run go run app.go hello or build the application with go build and execute the binary like: ./app hello

Guidelines

• The cmd module is where you will create your commands. Create a file for each command following the example of cmd/hello.go

• The flag_variables.go is used to declare variables that will receive the flags values, I did this to reuse the variables instead of creating new ones for each command.

  • Example: If have two commands with the variable var source string. You can declare the source in command A file and reuse it in command B file but it will get messy to know where the variables are declared. You can create a new variable but probably it will have a name almost equal to source and it's redundant because they're for the same thing.

• The core module is where you put things that's common and/or can be used to all your application like the application configuration

  • The config.go offers basic methods to work with the application configuration, you can create your own methods here
  • The init.go is where you put things that you will expose to other packages like the AppConfiguration
