Another framework ...

Yesterday I released my first Python framework. No, not another one. This is in the world - another one. And for me so far the first. And I admit that he is the first of its kind. It is a framework for building custom servers. And they will be created through the config. Wow, let's create now ...

---

In the beginning there was a config

So, config. Since we have already installed the framework by this point. And if not, then it's easy and simple to do with the command:

pip3 install idewavecore==0.0.1
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
    

This is assuming you have Python 3.6+, internet, and computer .

The config itself looks something like this:

# settings.yml
settings:
  servers: !inject config_dir/servers.yml
  db_connections:
    sqlite:
      host: ~
      username: ~
      password: ~
      # default mysql 3306, postgresql 5432, sqlite don't need port
      port: ~
      # currently allowed: mysql, postgresql, sqlite
      dialect: sqlite
      # supported drivers:
      # mysql: mysqlconnector, pymysql, pyodbc
      # postgresql: psycopg2, pg8000, pygresql
      driver: ~
      # to use with sqlite this should be absolute db path
      # can be empty to keep db in memory (sqlite only)
      db_name: ~
      charset: ~

And now I want to say thank you to everyone who read my post to the end. I would be grateful for any constructive comments. Even if my framework is not the first of its kind, I want to bring it as close as possible to this bar.
