How to set pyls.configurationSources?

[lucas-mior]

python-language-server's README goes as follows:

The default configuration source is pycodestyle. Change the pyls.configurationSources setting to ['flake8'] in order to respect flake8 configuration instead.
Overall configuration is computed first from user configuration (in home directory), overridden by configuration passed in by the language client, and then overriden by configuration discovered in the workspace.
To enable pydocstyle for linting docstrings add the following setting in your LSP configuration:
"pyls.plugins.pydocstyle.enabled": true

How is it done with this vim 9 lsp?

From :help lsp-cfg-workspaceConfig:

workspaceConfig (Optional) a json encodable value that will be sent to
                the language server after initialization as the       
                "settings" in a "workspace/didChangeConfiguration"    
                notification.  Refer to the language server           
                documentation for the values that will be accepted in 
                this notification.  This configuration is also used to
                respond to the "workspace/configuration" request      
                message from the language server.                     

Given that pyls configures options through workspaceConfig, this seems like the place to configure it.

(Just figured this out myself setting things up.)

Here's an example from my .vimrc that is working:

call lsp#lsp#AddServer([#{                       
  \ name: 'python-language-server',              
  \ filetype: ['python'],                        
  \ path: '/home/ptgolden/.local/bin/pylsp',     
  \ workspaceConfig: {                           
  \   'pylsp': {                                 
  \     'configurationSources': [],

  \       'autopep8': {                          
  \         'enabled': 0,                        
  \       },

  \       'pycodestyle': {                       
  \         'enabled': 0,                        
  \       },

  \     }                                        
  \   }                                          
  \ }                                            
  \ }])
