I wrote an article on MQTT in WEB + DB PRESS vol 88
Released August 22, 2015 WEB+DB PRESS vol88 >` _ to 速習 MQTT titled allowed to write an article about MQTT I had you.
The contents are as follows.
- What is MQTT
- Usage scene of MQTT
- Features of MQTT
- Comparison with other protocols
- Try using MQTT
As described in the title "Hayami," it is content that explains the contents of the protocol that MQTT is unable to hear, which is the main explanation of usage scenes and features. Although we try to implement try once using the MQTT, apps that use the MQTT at the point that in the python, eclipse paho thanks There is also a very Implementation is completed in a short row, and the amount is honestly high.
Recently it has become completely buzzword, and I have gradually come to see discourses such as "MQTT is the protagonist of the IoT era" and "MQTT can do all it". The contents of this time aimed to convey the actual situation of MQTT as accurately as possible. The use of MQTT is limited, and of course there are usage forms that are perfectly suitable, but I think that there are many cases where it is better to use other protocols. I hope to be able to communicate the neighborhood without excess or deficiency.
Sphinx InDesign Builder
Well, it is the main issue.
I wrote this in reStructuredText (rst) format. However, since in the rst form it knew that the variety is its work after the occurrence, Sphinx Indesign Builder has created a Spinx extension called.
% pip install sphinxcontrib_indesignbuilder
After installing with, in conf.py
extensions = ['sphinxcontrib.indesignbuilder']
The preparation is completed if it writes.
later,
% sphinx-build -b singlewebdb -d build/doctrees source build/singlewebdb
If, build/singlewebdb InDesign XML files for use with WEB + DB PRESS in will be created. The one marked with "single" can be put together in one xml file, it is possible to combine it into one. Editing WEB + DB PRESS will push this XML into InDesign, placing float elements such as diagrams, you will be ready to create PDF. It was a hassle that was almost the same as using md2inao. (However, note that among the functions that can be realized with md2inao, currently only functions required for this manuscript are implemented)
Actually, since we need human power to place the float elements, it is not a consistent flow from rst format file to PDF. For that, InDesgin power seems to be quite necessary.
It should be noted that, webdb as with the, is was created this time sphinx extension for WEB + DB PRESS. In other books and magazines, since the style naming convention is different, it can not be applied as it is. However, if you refer to the extension you created this time, it is fairly easy to implement another extension that conforms to other style naming conventions. Perhaps if you read a certain configuration file, it may be possible to export the XML according to that style naming convention by itself. If so, implementation is no longer necessary.
The reStructuredText (rst) format is also important in that it has high readability even in its original form, but its high extensibility is due to the extension point being decided. For example, we can flexibly respond to requests that "I want to express this part of this sentence specially". As a result, expressiveness is much higher than other description formats.
Summary
- I wrote an article on MQTT in WEB + DB PRESS vol 88
- It is contents to explain what MQTT can do and what I can not do
- We implemented the Sphinx extension called Sphinx InDesign Builder
- Drafted in reStructuredText (rst) format
WEB+DB PRESS vol88 >` _ the development of mobile development and LINE, please buy by all means because it also listed articles about Elixir.
