How to create a custom CLI and use it in Symfony (part2)

Part 1

1- file and folder structure

2- creation of this structure

3- mandatory files for the bundle

Part 2

4- creation of the command :-D

5- push it in the packagist

6- installed it in a Symfony project and run the command

Let’s continue

4- creation of the command

Before creating the command we need symfony console component version 5.3, so let’s run `composer require symfony/console `, after that symfony/console will be installed and you will see it in your composer.json file and the composer.lock file will be created,

In src/Command/CoffeCommand.php we need 2 mendatory functions

/**here we set ower command*/

public static $defaultName = ‘you:make:me:coffee’;

/**here we configure it */

protected function configure(): void

{

}

/**here we execute the code when de command is called */

protected function execute(InputInterface $input, OutputInterface $output): int

{

}

in execute function is where you can do your logic and return what you want, in our case the execute function return a INT value, We will see why !

In ./bin/console we need to instantiate our empty command, of course our command do nothing for the moment

now in terminal run `php bin/console list`, you should see this

its the default name of the command (check src/Command/CoffeCommand.php => ligne15)

let’s add our code inside configure() and execute() functions, to make a delicieuse coffee :

and now locally run `php bin/console you:make:me:coffee`, you will see this :

5- push it in the packagist

1- push your code to github repo [BE CARFULL : change the name of the repo because « coffeeshop/maker-coffee-bundle » is already taken ;-)]

2- signing in packagiste (or create an account)

3- copy / pasta :-p the github url in ‘SUBMIT SECTION’ of your packagist account :

4- after check submit your package: when All it’s done you will get this

Wonderfull you get your package in packagaiste, ignore for the moment the errors & warnings, you can fix it later (StackOverFlow i am invok you now …)

now let’s try to install it in syfmony project, Rhhoooo i can not wait let’s do it

6- installed it in a Symfony project and run the command

1- init an empty Symfony project or use a sandbox symfony project to test (it’s a little ecological)

2- and run composer require name of your package as Packagist have set it

3- play your commands and have fun

Et Voila !
