I wrote about \u201cHy\u201d<\/strong><\/em> language in an earlier<\/strong><\/em><\/a> article. Since then I have been exploring the language some more, trying to get a better understanding of its features.\u00a0<\/span><\/p>\n

The following example uses inheritance<\/strong><\/em> to model different types of \u201cSpace\u201d<\/strong><\/em> objects such as Asteroid<\/strong><\/em>, SpaceShip<\/strong><\/em> and Planet<\/strong><\/em>. It is taken from an earlier article <\/strong><\/em><\/a><\/strong>that explained how \u201cMultimethods\u201d<\/strong><\/em> in Lisp<\/strong><\/em> can be used to model dynamic<\/em> dispatch<\/em> of method calls.<\/p>\n

\"Inheritance<\/a>
Inheritance Example<\/strong><\/figcaption><\/figure>\n

In the above code, I first define classes to model the different \u201cspace objects\u201d<\/strong><\/em>. Some of these classes define a \u201ccollide\u201d<\/strong><\/em> method and print a string describing which space object collides with what other space object. Finally, I create instances of these classes and invoke the \u201ccollide\u201d<\/strong><\/em> method. Here is the output:<\/p>\n

\"Output\"<\/a>
Output<\/strong><\/figcaption><\/figure>\n

As expected, in the case of Asteroid<\/strong><\/em> and Mars<\/strong><\/em>, their overriding \u201ccollide\u201d<\/strong><\/em> method is used, but for others the default method defined in \u201cSpaceObject\u201d<\/strong><\/em> is invoked.\u00a0<\/span><\/p>\n

For the next example, I decided to use the popular \u201clangchain\u201d<\/strong><\/em> framework to interact with an \u201cLLM\u201d<\/strong><\/em>. Here is the code.<\/p>\n

\"Langchain<\/a>
Langchain Example<\/strong><\/figcaption><\/figure>\n

The code demonstrates a very basic interaction mode of \u201clangchain\u201d<\/strong><\/em>, and uses an open-source LLM<\/strong><\/em> from \u201cHuggingFaceHub\u201d<\/strong><\/em>. Make sure you get the required API token.<\/p>\n

Here is the output from the program:<\/p>\n

Based on the limited time that I have spent with \u201cHy\u201d<\/strong><\/em> language, I find it is very usable and easy to adopt if you already know Python<\/strong><\/em>.\u00a0<\/span><\/p>\n
