pkg/messaging — the high-level Messaging API, and the one to reach for. A MessagingClient mirrors the Nim MessagingClient: it owns a node and exposes Start/Stop/Close, Subscribe/Unsubscribe, Send, and a typed Events() stream. See examples/messaging for a runnable demo.
pkg/kernel — the low-level kernel (waku_*) protocols: relay, store, filter, lightpush, discovery and peer management. Unsupported and subject to change without notice.

Install

go get github.com/logos-messaging/logos-delivery-go-bindings

Building

liblogosdelivery is required at compile time. This repository is a Nimble package declaring the minimum logos-delivery its C ABI works against, so a consumer picks the revision and can upgrade without a release here.

nimble setup                # resolve logos-delivery at the pinned revision
nimble liblogosdelivery     # build it, via logos-delivery's own build task

The library is written to logos-delivery's package directory. Set LIBLOGOSDELIVERY_OUT to have it copied somewhere of your choosing, and pass NIM_PARAMS for build defines — -d:disable_rln builds without zerokit, so no Rust toolchain is needed:

LIBLOGOSDELIVERY_OUT="$PWD/build" NIM_PARAMS="-d:disable_rln" nimble liblogosdelivery

Then point cgo at the headers and the library:

export CGO_CFLAGS="-I$(nimble path logos_delivery | tail -1)/library"
export CGO_LDFLAGS="-L$PWD/build -llogosdelivery -Wl,-rpath,$PWD/build"

go build ./...
go test ./pkg/messaging/

Development

No clone of logos-delivery is needed: nimble setup fetches it at the pinned revision.

To work against a local checkout instead — testing a logos-delivery change before repinning here — shadow the resolved package:

nimble develop /path/to/logos-delivery

To choose a specific revision, require it from your own .nimble — it satisfies the range here and wins resolution:

requires "https://github.com/logos-messaging/logos-delivery#<rev>"
