The ``node-wot`` client consumes such a specification to provide these interactions for the developer. -``node-wot`` already has protocol bindings like HTTP, CoAP, Modbus, MQTT etc. which can be used in nodeJS or in web browsers. -Since ``hololinked`` offers the possibility of HTTP bindings for devices, such a JSON Thing description is auto generated by -the class to be able to use by the node-wot client. To use the node-wot client on the browser: - -.. literalinclude:: code/node-wot/intro.js - :language: javascript - :linenos: - -There are few reasons one might consider to use ``node-wot`` compared to traditional HTTP client, first and foremost being -standardisation across different protocols. Irrespective of hardware protocol support, including HTTP bindings from -``hololinked``, one can use the same API. For example, one can directly issue modbus calls to a modbus device while -issuing HTTP calls to ``hololinked`` ``Thing``s. Further, node-wot offers validation of property types, action payloads and -return values, and event data without additional programming effort. - diff --git a/doc/source/howto/code/eventloop/import.py b/doc/source/howto/code/eventloop/import.py deleted file mode 100644 index 7054890..0000000 --- a/doc/source/howto/code/eventloop/import.py +++ /dev/null @@ -1,8 +0,0 @@ -from hololinked.client import ObjectProxy -from hololinked.server import EventLoop -

If you have a requirement to control and capture data from your hardware/instrumentation remotely through your network, show the data in a browser/dashboard, provide a GUI or run automated scripts, `hololinked` can help. Even if one wishes to do hardware control/data-acquisition in a single computer or a small setup without networking concepts, one can still separate the concerns of the GUI and the other tools that interact with the device & the device itself.

See a list of currently supported features [below](#currently-supported).

-Ultimately, as expected, the redirection from the HTTP side to the object is mediated by ZeroMQ which implements the fully fledged RPC server that queues all the HTTP requests to execute them one-by-one on the hardware/object. The HTTP server can also communicate with the RPC server over ZeroMQ's INPROC (for the non-expert = multithreaded applications, at least in python) or IPC (for the non-expert = multiprocess applications) transport methods. In the example above, IPC is used by default. There is no need for yet another TCP from HTTP to TCP to ZeroMQ transport athough this is also supported.

-Serialization-Deserialization overheads are also already reduced.

The HTTP server can also communicate with the RPC server over ZeroMQ's INPROC (for the non-expert = multithreaded applications, at least in python) or IPC (for the non-expert = multiprocess applications) transport methods. In the example above, IPC is used by default. There is no need for yet another TCP from HTTP to TCP to ZeroMQ transport athough this is also supported.

The HTTP server can also communicate with the RPC server over ZeroMQ's INPROC (for the non-expert = multithreaded applications, at least in python) or IPC (for the non-expert = multiprocess applications) transport methods. In the example above, IPC is used by default. There is no need for yet another TCP from HTTP to TCP to ZeroMQ transport athough this is also supported.

Serialization-Deserialization overheads are also already reduced. For example, when pushing an event from the object which gets automatically tunneled as a HTTP SSE or returning a reply for an action from the object, there is no JSON deserialization-serialization overhead when the message passes through the HTTP server. The message is serialized once on the object side but passes transparently through the HTTP server. @@ -312,8 +313,6 @@ Again, please check examples or the code for explanations.

- Ultimately, as expected, the redirection from the HTTP side to the object is mediated by ZeroMQ which implements the fully fledged RPC server that queues all the HTTP requests to execute them one-by-one on the hardware/object. The HTTP server can also communicate with the RPC server over ZeroMQ's INPROC (for the non-expert = multithreaded applications, at least in python) or IPC (for the non-expert = multiprocess applications) transport methods. In the example above, INPROC is used by default. There is no need for yet another TCP from HTTP to TCP to ZeroMQ transport athough this is also supported.
Serialization-Deserialization overheads are also already reduced. For example, when pushing an event from the object which gets automatically tunneled as a HTTP SSE or returning a reply for an action from the object, there is no JSON deserialization-serialization overhead when the message passes through the HTTP server. The message is serialized once on the object side but passes transparently through the HTTP server.

Therefore, we ask you to investigate carefully, collect information and describe the issue in detail in your report. Please complete the following steps in advance to help us fix any potential bug as fast as possible. - -- Make sure that you are using the latest version. -- Determine if your bug is really a bug and not an error on your side e.g. using incompatible environment components/versions (Make sure that you have read the [documentation](https://hololinked.readthedocs.io/en/latest/index.html). If you are looking for support, you might want to check [this section](#i-have-a-question)). -- To see if other users have experienced (and potentially already solved) the same issue you are having, check if there is not already a bug report existing for your bug or error in the [bug tracker](https://github.com/VigneshVSV/hololinkedissues?q=label%3Abug). -- Also make sure to search the internet (including Stack Overflow) to see if users outside of the GitHub community have discussed the issue. -- Collect information about the bug: +- Provide project and platform versions (OS, python version etc.), depending on what seems relevant. +- +One may submit a bug report at any level of information.

If it has, add a comment to the existing idea instead of opening a new one. -- Find out whether your idea fits with the scope and aims of the project. It's up to you to make a strong case to convince the project's developers of the merits of this feature. - - -#### How Do I Submit a Good Enhancement Suggestion? - -Enhancement suggestions are tracked as [GitHub issues](https://github.com/VigneshVSV/hololinked/issues). - -- Use a **clear and descriptive title** for the issue to identify the suggestion. -- Provide a **step-by-step description of the suggested enhancement** in as many details as possible. -- **Describe the current behavior** and **explain which behavior you expected to see instead** and why. At this point you can also tell which alternatives do not work for you. -- You may want to **include screenshots and animated GIFs** which help you demonstrate the steps or point out the part which the suggestion is related to. You can use [this tool](https://www.cockos.com/licecap/) to record GIFs on macOS and Windows, and [this tool](https://github.com/colinkeenan/silentcast) or [this tool](https://github.com/GNOME/byzanz) on Linux. -- **Explain why this enhancement would be useful** to most hololinked users.

For those familiar with RPC & web development - This package is an implementation of a ZeroMQ-based Object Oriented RPC with customizable HTTP end-points. A dual transport in both ZMQ and HTTP is provided to maximize flexibility in data type, serialization and speed, although HTTP is preferred for networked applications. Even through HTTP, the paradigm of working is HTTP-RPC only, to queue the commands issued to the hardware. If one is looking for an object oriented approach towards creating components within a control or data acquisition system, or an IoT device, one may consider this package. -[![Documentation Status](https://readthedocs.org/projects/hololinked/badge/?version=latest)](https://hololinked.readthedocs.io/en/latest/?badge=latest) [![Maintainability](https://api.codeclimate.com/v1/badges/913f4daa2960b711670a/maintainability)](https://codeclimate.com/github/VigneshVSV/hololinked/maintainability) [![PyPI](https://img.shields.io/pypi/v/hololinked?label=pypi%20package)](https://pypi.org/project/hololinked/) [![PyPI - Downloads](https://img.shields.io/pypi/dm/hololinked)](https://pypistats.org/packages/hololinked) +[![Documentation Status](https://readthedocs.org/projects/hololinked/badge/?version=latest)](https://hololinked.readthedocs.io/en/latest/?badge=latest) [![PyPI](https://img.shields.io/pypi/v/hololinked?label=pypi%20package)](https://pypi.org/project/hololinked/) [![PyPI - Downloads](https://img.shields.io/pypi/dm/hololinked)](https://pypistats.org/packages/hololinked) ### To Install From 002b804ba989eee7492b66b3e9900a28b14b1d1f Mon Sep 17 00:00:00 2001 From: Vignesh Venkatasubramanian Vaidyanathan <62492557+VigneshVSV@users.noreply.github.com> Date: Sat, 13 Jul 2024 08:55:37 +0200 Subject: [PATCH 073/119] set_properties method signature changed --- hololinked/client/proxy.py | 20 +++++++++++--------- 1 file changed, 11 insertions(+), 9 deletions(-) diff --git a/hololinked/client/proxy.py b/hololinked/client/proxy.py index 8041eb2..d79404e 100644 --- a/hololinked/client/proxy.py +++ b/hololinked/client/proxy.py @@ -381,20 +381,20 @@ def get_properties(self, names : typing.List[str], noblock : bool = False) -> ty return method(names=names) - def set_properties(self, values : typing.Dict[str, typing.Any], oneway : bool = False, - noblock : bool = False) -> None: + def set_properties(self, oneway : bool = False, noblock : bool = False, + **properties : typing.Dict[str, typing.Any]) -> None: """ set properties whose name is specified by keys of a dictionary Parameters ---------- - values: Dict[str, Any] - name and value of properties to be set oneway: bool, default False only send an instruction to set the property but do not fetch the reply.

`hololinked` is a server side pythonic package suited for instrumentation control and data acquisition over network, especially with HTTP. If you have a requirement to control and capture data from your hardware/instrumentation, show the data in a browser/dashboard, provide a GUI or run automated scripts, `hololinked` can help. Even if one wishes to do hardware control/data-acquisition in a single computer or a small setup without networking concepts, one can still separate the concerns of the tools that interact with the hardware & the hardware itself. +For beginners - `hololinked` is a server side pythonic package suited for instrumentation control and data acquisition over network, especially with HTTP. If you have a requirement to control and capture data from your hardware/instrumentation, show the data in a browser/dashboard, provide a GUI or run automated scripts, `hololinked` can help. Even for isolated applications or a small lab setup without networking concepts, one can still separate the concerns of the tools that interact with the hardware & the hardware itself.

-For those familiar with RPC & web development - This package is an implementation of a ZeroMQ-based Object Oriented RPC with customizable HTTP end-points. A dual transport in both ZMQ and HTTP is provided to maximize flexibility in data type, serialization and speed, although HTTP is preferred for networked applications. Even through HTTP, the paradigm of working is HTTP-RPC only, to queue the commands issued to the hardware. If one is looking for an object oriented approach towards creating components within a control or data acquisition system, or an IoT device, one may consider this package. +For those familiar with RPC & web development - This package is an implementation of a ZeroMQ-based Object Oriented RPC with customizable HTTP end-points.

The HTTP server can also communicate with the RPC server over ZeroMQ's INPROC (for the non-expert = multithreaded applications, at least in python) or IPC (for the non-expert = multiprocess applications) transport methods. In the example above, INPROC is used by default, which is also the fastest transport between two threads - one thread serving the HTTP server and one where the Thing's properties, actions and events run. There is no need for yet another TCP from HTTP to TCP to ZeroMQ transport athough this is also supported. - -> If you do not like queueing certain commands, you can always manually thread out or create async functions for the time being. Overcoming queueing will be natively supported in future versions. - -Serialization-Deserialization overheads are also already reduced. For example, when pushing an event from the object which gets automatically tunneled as a HTTP SSE or returning a reply for an action from the object, there is no JSON deserialization-serialization overhead when the message passes through the HTTP server. The message is serialized once on the object side but passes transparently through the HTTP server. When not implemented in this fashion, it can be unnecessarily time consuming when sending large data like images or large arrays through the HTTP server. If you hand-write a RPC client within a HTTP server, you may have to work a little harder to get this optimization. - -One may use the HTTP API according to one's beliefs (including letting the package auto-generate it), although it is mainly intended for web development and cross platform clients like the [node-wot](https://github.com/eclipse-thingweb/node-wot) HTTP(s) client.
