Modules declare go 1.27.1 and the build images follow. go fix applied the modernizers; omitzero is not applied, since it changes what the JSON says. Co-authored-by: Hanzo Dev <[email protected]>
ZMQ4 Examples
This directory contains examples demonstrating the usage of the zmq4 package.
Basic Examples
Hello World (REQ-REP)
Simple request-reply pattern:
# Terminal 1
go run hwserver.go
# Terminal 2
go run hwclient.go
Pub-Sub with Envelope
Publisher-subscriber pattern with message envelopes:
# Terminal 1
go run psenvpub.go
# Terminal 2
go run psenvsub.go
Request-Reply with Workers
Load-balanced request distribution:
# Terminal 1
go run rrworker.go
# Terminal 2
go run rrclient.go
Router-Dealer
Advanced routing pattern:
go run rtdealer.go
CZMQ Compatibility Testing
The compatibility_test.go example demonstrates interoperability between pure Go and CZMQ implementations.
Prerequisites
To run the compatibility test, you need CZMQ installed:
Ubuntu/Debian:
sudo apt-get install libczmq-dev libzmq3-dev
macOS:
brew install czmq
Running the Compatibility Test
# Build and run with czmq4 tag
go run -tags czmq4 compatibility_test.go
This example creates a CZMQ publisher and a pure Go subscriber to verify that messages can be exchanged between the two implementations.
Pure Go vs CZMQ
Pure Go (Default)
All examples run with the pure Go implementation by default:
go run hwserver.go # Uses pure Go implementation
With CZMQ
To run any example with CZMQ compatibility:
go run -tags czmq4 hwserver.go # Uses CZMQ for socket operations
Testing Interoperability
You can test interoperability by running one component with CZMQ and another without:
# Terminal 1: Server using CZMQ
go run -tags czmq4 hwserver.go
# Terminal 2: Client using pure Go
go run hwclient.go
Both should communicate seamlessly, demonstrating protocol compatibility.
