If the argument of 'source' ends in '.star' it will be interpreted as a starlark script. If the argument of 'source' is '-' an interactive starlark repl will be started. For documentation on how the starlark execution environment works see Documentation/cli/starlark.md. The starlark API is autogenerated from the JSON-RPC API by script/gen-starlark-bindings.go. In general for each JSON-RPC API a single global starlark function is created. When one of those functions is called (through a starlark script) the arguments are converted to go structs using reflection. See unmarshalStarlarkValue in pkg/terminal/starbind/conv.go. If there are no type conversion errors the JSON-RPC call is executed. The return value of the JSON-RPC call is converted back into a starlark value by interfaceToStarlarkValue (same file): * primitive types (such as integers, floats or strings) are converted by creating the corresponding starlark value. * compound types (such as structs and slices) are converted by wrapping their reflect.Value object into a type that implements the relevant starlark interfaces. * api.Variables are treated specially so that their Value field can be of the proper type instead of always being a string. Implements #1415, #1443
