                         The  configuration directory  is now stored in  datasette.config_dir , making it available to plugins. Thanks, Chris Amico.

plugin_hooks:id1,plugin_hooks,id1,Plugin hooks,"Datasette  plugins  use  plugin hooks  to customize Datasette's behavior. These hooks are powered by the  pluggy  plugin system. 
         Each plugin can implement one or more hooks using the  @hookimpl  decorator against a function named that matches one of the hooks documented on this page. 
         When you implement a plugin hook you can accept any or all of the parameters that are documented as being passed to that hook. 
         For example, you can implement the  render_cell  plugin hook like this even though the full documented hook signature is  render_cell(row, value, column, table, database, datasette) : 
         @hookimpl
def render_cell(value, column):
    if column == ""stars"":
        return ""*"" * int(value)
