Providers and Languages

Languages and providers run as their own executables, so debugging isn't as simple as attaching to the engine.

Instead you'll have to launch them in a debugger and provide the information for connecting to them to the engine via environmental variables.

Languages

Languages work very similary to Providers.

Instead of PULUMI_DEBUG_PROVIDERS environmental variable, you use PULUMI_DEBUG_LANGUAGES like so:

PULUMI_DEBUG_LANGUAGES="go:12345" pulumi preview

After opening your language executable (eg pulumi-language-go) in your debugger of choice.
