Command to run attach().

[JoseConseco]

In past we could use attach(host, port, config) :

But now I'm not sure how do I pass the adapter and config arguments ? My objective is to attach to debugpy: localhost, 5678, without constantly having to go through setup settings:

I tried something like: lua require'dap'.attach(require'dap'.adapter.python={request='attach','0.0.0.0', 5678},{})
but it does not seem to work...

You could call dap.run() directly if you want to skip the configurations prompt. E.g. dap.run(dap.configurations[vim.bo.filetype][3]) if you know the configuration entry you want is on position 3.

Another option is to use dap.continue() the first time and then for sub-sequent debug sessions use dap.run_last() to skip the prompt - it will immediately re-use the last configuration.

Thanks to your answer I manage to get this:
:lua require'dap'.run({type='python', request='attach', host='127.0.0.1', port=5678})
So finally I do not have to enter host and port every time (or press ret 3x - to use default values)

If you always use the same host and port number you could also just add a configuration that has fixed host/port entries instead of a configuration that uses the input function.

The configurations are meant to be customized/user specific.
