Any C++ client requires the jsoncons and cppzmq package: those are automatically downloaded and used when compiling via cmake. For details see programming/zmqRemoteApi/clients/cpp/, which contains several examples.

ØMQ bindings for Node.js. The goals of this library are:Semantically similar to the native ØMQ library, while sticking to JavaScript idioms.Use modern JavaScript and Node.js features such as async/await and async iterators.High performance.Fully usable with TypeScript (3+).Useful linksZeroMQ.js API reference.ZeroMQ project documentation.Note: The Node.js examples on zeromq.org do not yet reflect the new API, but the Guide in particular is still a good introduction to ZeroMQ for new users.Table of contentsInstallationPrebuilt binariesBuilding from sourceExamplesPush/PullPub/SubReq/RepTypeScriptMore examplesCompatibility layer for version 4/5ContributionHistoryInstallationInstall ZeroMQ.js with prebuilt binaries:npm install zeromq@6.0.0-beta.16Requirements for using prebuilt binaries:Node.js 10.2+ or Electron 3+ (requires a N-API version 3+)Prebuilt binariesThe following platforms have a prebuilt binary available:Linux on x86-64 with libstdc++.so.6.0.21+ (glibc++ 3.4.21+), for example:Debian 9+ (Stretch or later)Ubuntu 16.04+ (Xenial or later)CentOS 8+Linux on x86-64 with musl, for example:Alpine 3.3+MacOS 10.9+ on x86-64Windows on x86/x86-64If a prebuilt binary is not available for your platform, installing will attempt to start a build from source.
If a prebuilt binary is unavailable or if you want to pass certain options during build, you can build this package from source.Make sure you have the following installed before attempting to build from source:Node.js 10+ or Electron 3+A working C++17 compiler toolchain with makePython 3 with Node 12.13+ (or legacy Python 2.7)CMake 2.8+curlTo install from source:npm install zeromq@6.0.0-beta.16 --build-from-sourceIf you want to link against a shared ZeroMQ library, you can build skip downloading libzmq and link with the installed library instead as follows:npm install zeromq@6.0.0-beta.16 --zmq-sharedIf you wish to use any DRAFT sockets then it is also necessary to compile the library from source:npm install zeromq@6.0.0-beta.16 --zmq-draftExamplesNote: These examples assume the reader is familiar with ZeroMQ. If you are new to ZeroMQ, please start with the ZeroMQ documentation.More examples can be found in the examples directory.
Creates a producer to push information onto a socket.const zmq = require("zeromq")async function run() const sock = new zmq.Push await sock.bind("tcp://127.0.0.1:3000") console.log("Producer bound to port 3000") while (true) await sock.send("some work") await new Promise(resolve => setTimeout(resolve, 500) ) run()worker.jsCreates a worker to pull information from the socket.const zmq = require("zeromq")async function run() const sock = new zmq.Pull sock.connect("tcp://127.0.0.1:3000") console.log("Worker connected to port 3000") for await (const [msg] of sock) console.log("work: %s", msg.toString()) run()Pub/SubThis example demonstrates using zeromq in a classic Pub/Sub, Publisher/Subscriber, application.
Create the publisher which sends messages.const zmq = require("zeromq")async function run() const sock = new zmq.Publisher await sock.bind("tcp://127.0.0.1:3000") console.log("Publisher bound to port 3000") while (true) console.log("sending a multipart message envelope") await sock.send(["kitty cats", "meow!"]) await new Promise(resolve => setTimeout(resolve, 500) ) run()subscriber.jsCreate a subscriber to connect to a publisher's port to receive messages.const zmq = require("zeromq")async function run() const sock = new zmq.Subscriber sock.connect("tcp://127.0.0.1:3000") sock.subscribe("kitty cats") console.log("Subscriber connected to port 3000") for await (const [topic, msg] of sock) console.log("received a message related to:", topic, "containing message:", msg) run()Req/RepThis example illustrates a request from a client and a reply from a server.
This library provides typings for TypeScript version 3.0.x and later.RequirementsFor TypeScript version >= 3:compilerOptionsFor TypeScript version either set compilerOptions.target to esnext or later (e.g. es2018)or add the following, or similar, libraries to compilerOptions.lib (and include their corresponding polyfills if needed): es2015, ESNext.AsyncIterableExample Usageimport Request from "zeromq"// or as namespaceimport * as zmq from "zeromq"const reqSock = new Request()//...const repSock = new zmq.Reply()More examplesMore advanced examples can be found in the examples directory of this repository.Or you can browse the API reference documentation to see all socket types, methods & options as well as more detailed information about how to apply them.
The next generation version of the library features a compatibility layer for ZeroMQ.js versions 4 and 5. This is recommended for users upgrading from previous versions.Example:const zmq = require("zeromq/v5-compat")const pub = zmq.socket("pub")const sub = zmq.socket("sub")pub.bind("tcp://*:3456", err => if (err) throw err sub.connect("tcp://127.0.0.1:3456") pub.send("message") sub.on("message", msg => // Handle received message... ))ContributionIf you are interested in making contributions to this project, please read the following sections.
Socket and context options can be set at runtime, even if they are not implemented by this library. By design, this requires no recompilation if the built version of ZeroMQ has support for them. This allows library users to test and use options that have been introduced in recent versions of ZeroMQ without having to modify this library. Of course we'd love to include support for new options in an idiomatic way.Options can be set as follows:const Dealer = require("zeromq")/* This defines an accessor named 'sendHighWaterMark', which corresponds to the constant ZMQ_SNDHWM, which is defined as '23' in zmq.h. The option takes integers. The accessor name has been converted to idiomatic JavaScript. Of course, this particular option already exists in this library. */class MyDealer extends Dealer get sendHighWaterMark(): number return this.getInt32Option(23) set sendHighWaterMark(value: number) this.setInt32Option(23, value) const sock = new MyDealer(sendHighWaterMark: 456)When submitting pull requests for new socket/context options, please consider the following:The option is documented in the TypeScript interface.The option is only added to relevant socket types, and if the ZMQ_ constant has a prefix indicating which type it applies to, it is stripped from the name as it is exposed in JavaScript.The name as exposed in this library is idiomatic for JavaScript, spelling out any abbreviations and using proper camelCase naming conventions.The option is a value that can be set on a socket, and you don't think it should actually be a method.TestingThe test suite can be run with:npm installnpm run buildnpm run testThe test suite will validate and fix the coding style, run all unit tests and verify the validity of the included TypeScript type definitions.Some tests are not enabled by default:API Compatibility tests from ZeroMQ 5.x have been disabled by default. You can include the tests with INCLUDE_COMPAT_TESTS=1 npm run testSome transports are not reliable on some older versions of ZeroMQ, the relevant tests will be skipped for those versions automatically.PublishingTo publish a new version, run:npm version git push && git push --tagsWait for continuous integration to finish. Prebuilds will be generated for all supported platforms and attached to a Github release. Documentation is automatically generated and committed to gh-pages. Finally, a new NPM package version will be automatically released.
Pymatbridge communicates with Matlab using zeromq. So before installingpymatbridge you must have zmqlibrary and pyzmq installed on yourmachine. If you intend to use the Matlab magic extension, you'll also needIPython. To make pymatbridge work properly,please follow the following steps.
For many of the methods used to install both ROSCO and the ROSCO toolbox, both Anaconda and CMake are necessary. Anaconda is a popular package manager used to distribute software packages of various types. Anaconda is used to download requisite packages and distribute pre-compiled versions of the ROSCO tools. CMake is a build configuration system that creates files as input to a build tool like GNU Make, Visual Studio, or Ninja. CMake does not compile code or run compilers directly, but rather creates the environment needed for another tool to run compilers and create binaries. CMake is used to ease the processes of compiling the ROSCO controller locally. For more information on CMake, please see understanding CMake in the OpenFAST documentation.
The most recent tagged version releases of the controller are available for download. One can simply download these compiled binary files for their system and point to them in their simulation tools (e.g. through DLL_FileName in the ServoDyn input file of OpenFAST).
Using the popular package manager, Anaconda, the tagged 64-bit versions of ROSCO are available through the conda-forge channel.In order to download the most recently compiled version release, from an anaconda powershell (Windows) or terminal (Mac/Linux) window, create a new anaconda virtual environment: 2ff7e9595c
