Built the missing piece that connects the ksp-bridge to a real KSP
instance via kRPC. This adds a typed service client on top of the
existing KRPCClient, plus the SpaceCenter-specific extraction logic
that pulls the universe state from a running KSP save.
@kerbal-rt/krpc-client
- types.ts — runtime representation of kRPC Type descriptors
(TypeCode enum, KrpcType interface, decodeKrpcType, typeName)
- decoder.ts — kRPC value codec: primitive decode/encode, class refs,
enums, collections (LIST/SET/TUPLE/DICTIONARY), system messages
(STATUS/SERVICES/STREAM/EVENT/PROCEDURE_CALL). 34 unit tests.
- services.ts — ServiceCache built from KRPC.GetServices() response.
Lookup by (service, procedure), enum value/name resolution. 12 tests.
- service-client.ts — KrpcServices: high-level invoke-by-name client.
loadServices() helper to connect + load catalog. 9 integration tests
with a mock kRPC server.
- schema.ts — added Set/Dictionary/Event/Expression types so the
decoder can handle system messages without external .proto files.
Also fixed a bug where 'STREAM' was being encoded as 0 due to
protobufjs's nested-enum string lookup.
ksp-bridge
- extract.ts — the actual SpaceCenter calls. ~280 procedure calls
per poll for a typical KSP save (UT, bodies, vessels, then per-body
and per-vessel class methods in parallel). Build the UniverseSnapshot.
- krpc-adapter.ts — rewrote to use KrpcServices (typed) instead of
the stub extract function. Supports an optional injected services
for testing.
- bridge.ts — uses the new ExtractedState type and buildSnapshot.
- index.ts — connects to kRPC; falls back to mock mode if no server.
- convert.ts — backward-compat shim, re-exports from extract.ts.
The ksp-bridge can now talk to a real KSP install. We do NOT need
the kRPC mod's .proto files on disk — the server's GetServices()
response is the source of truth for type info. Documented the full
list of procedures we call, the kRPC value encoding, and the new
architecture in ksp/README.md.
Tests: 119 total, all green. Typecheck and build clean across all 11
projects.
Bonus: fixed an integer-overflow bug in the krpc-client connect()
handshake (was passing 'RPC'/'STREAM' strings to protobufjs; its
nested-enum string lookup silently encodes as 0, which made the
stream handshake send the wrong type. Switched to numeric codes.)
