Pyright ignores configuration from custom toml files

[vprud]

Describe the bug

Option --project of command-line version of pyright does not support configuration in toml file. The configuration in toml files other than 'pyproject.toml` is ignored. If emit verbose diagnostics of pyright, it will show that it does not find any configuration file.

Code or Screenshots

For example, I will use configs folder, in which configuration files will be saved. Create configuration in configs/pyright.toml:

[tool.pyright]
typeCheckingMode = "strict"

and similarly in configs/pyright.json:

{
    "typeCheckingMode": "strict"
}

When running with toml configuration file:

pyright --project configs/pyright.toml --verbose

pyright writes that it cannot find configuration file:

Configuration file not found at <path to root>/configs/pyright.toml.

When running with json configuration file:

pyright --project configs/pyright.json --verbose

pyright writes that it found configuration file in ./configs/pyright.json and uploaded it:

Loading configuration file at <path to root>/configs/pyright.json

This behavior does not seem consistent for different formats of configuration file. It is expected that pyright will read toml file as well as json configuration file.

VS Code extension or command-line

$ pyright --version
pyright 1.1.360

This is by design. If you want to use a custom configuration, you should use the ".json" format. Support for ".toml" is provided only for integration with the standard "pyproject.toml" file that is commonly used for Python projects.

Reopening this as a feature request.

[erictraut]

I decided to implement this feature as part of #4366. It will be included in the next release.

[vprud]

Great, I believe it will be very useful.

This is included in pyright 1.1.365.
