Allow specifying multiple configuration files

[not-my-profile]

Is your feature request related to a problem? Please describe.
I'd like to have one pyrightconfig.json config for development environments like VS Code and one pyrightconfig-ci.json for the CI. The config for the CI turns out to be a superset of the other config file and I'd like to avoid having to duplicate the configuration.

Describe the solution you'd like
It would be nice if pyright could be invoked with multiple configuration files, e.g:

pyright -p pyrightconfig.json -p pyrightconfig-ci.json

where settings specified in a later configuration file would override the settings of earlier configuration files.

The configuration logic in pyright is already very complex because it needs to merge config information from pyrightconfig.json, language server settings, and command-line options.

Merging of multiple configuration files would add more complexity. I don't think it's a simple as one overriding another because some of the configurations options interact with others.

So we don't have any plans at this time to support multiple configuration files.

This could be something we reconsider in the future, but for now you'll need to use duplicate configuration files.

is there a way via the command line to override a setting in pyrightconfig.json? that would be great, but I couldn't find out how to do that from the documentation

A few options are available by command-line. Many are not. If you need to override those, you can emit a temporary pyrightconfig.json file and use the -p option from the command-line.
