It is quite probable that this is due to my incompetence with composer and apologies in advance if it is the case.

I tried installing this project with composer using:

composer require yswery/dns

The output is:

Using version ^1.0 for yswery/dns
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)

symfony/event-dispatcher suggests installing symfony/dependency-injection ()
symfony/event-dispatcher suggests installing symfony/http-kernel ()
react/event-loop suggests installing ext-event (~1.0 for ExtEventLoop)
Writing lock file
Generating autoload files

Then, I tried to run the example script that comes with the project (I edited the autoload.php path), using:

php vendor/yswery/dns/example/example.php

This fails with:

PHP Fatal error:  Class 'Psr\Log\AbstractLogger' not found in /home/nikos/vendor/yswery/dns/src/EchoLogger.php on line 22

I then deleted everything and git-cloned this repo, and run from inside the project folder composer install. That installed a whole lot more packages and example.php succeeded.

Am I doing sth wrong?

It seems to be a quirk with how Composer resolves dependencies. psr/log was not explicitly required by composer.json but came along with symfony/event-dispatcher as a dependency of a dependency. This does not seem to be a problem if you are cloning the repo, only if you are installing using composer. This next push will fix it.

Alright! Is there a delay for it to appear on packagist?
