Provide some way in the CLI to execute providers and get values out of them #1033
Description
buck2 audit providers exists which can give you some details about providers:
$ buck audit providers toolchains//:hspec-discover
toolchains//:hspec-discover (<unspecified>):
Providers([
DefaultInfo(
sub_targets={},
default_outputs=[ <build artifact out.link bound to toolchains//:hspec-discover (<unspecified>)> ],
other_outputs=[]
),
BinDirInfo( args=cmd_args(
<build artifact out.link bound to toolchains//:hspec-discover (<unspecified>)>,
"bin",
delimiter="/"
) ),
NixDynamicInfo( dynamic=DynamicValue<toolchains//:hspec-discover (<unspecified>)_0> ),
RunInfo( args=cmd_args( cmd_args(
<build artifact out.link bound to toolchains//:hspec-discover (<unspecified>)>,
"bin",
"hspec-discover",
delimiter="/"
) ) )
])
However, I can't figure out a way to actually build one of those and get the result if it's not a subtarget. Is this a thing in the CLI? I would like to be able to interactively poke around the build graph.
