Calling Lisp Functions from Elixir

Calling Lisp Functions from Elixir

In the last article I showed how we can simulate the idea of Lisp’s “closure” in Elixir. Today, I would like to demonstrate how we can call Lisp functions from Elixir using the NIF interface. What is the need to integrate Elixir with another language? I can think of two reasons: 1) We have a library […]

Closure in Lisp vs Elixir

Closure in Lisp vs Elixir

I started learning Elixir a week ago. Although this has been at the top of my To-do list for quite a while, I couldn’t take it up due to other commitments.  I love Elixir. It is a great functional programming language. Having programmed in Lisp for a long time, I immediately noticed the similarity between Lisp […]

Calling Lisp Functions from Go Language

In the previous post, we saw how to invoke a Go function from Lisp. In today’s post, I would like to explain how to go in the other direction, namely, how to call Lisp functins from Go. There are two ways to do this. The first approach is to load the Lisp DLL (like any […]

Calling Go Functions from Lisp

For the past few weeks I was travelling in the USA and had the pleasure of meeting several friends, some of whom are senior developers and architects. It was interesting to learn that many of them were either using Go language in their daily work, or were passionately endorsing the language! Due to lack of […]

CLPython: Python in Common Lisp – Part 2

Written by on July 22, 2017 in LISP, Programming, Python with 0 Comments

We looked at the basic features of CLPython in our last blog. In today’s post let us look at the support for Python classes. PYTEST 130 > (defun pyclass ()   (run  “class Employee:    def __init__(self, name, dept):      self.name = name      self.dept = dept    def dump(self):      print ‘Name […]

CLPython – Python in Common Lisp

Written by on July 7, 2017 in LISP, Python with 0 Comments

My work in the area of NLP requires me to work with several frameworks across multiple languages such as Java, Python and Lisp. Sometime ago I got a chance to experiment with CLPython, an open-source implementation of Python in Common Lisp. Although CLPython is not under active development now, I found it quite usable. In fact […]

Definite Clause Grammars in Lisp – Part 3

In today’s post, let us see how we can enhance the grammar representation discussed so far to include both Number constraint and Parse Tree. Fortunately, this turns out to be quite straightforward. Just as we do in Prolog, we need to include additional parameters, as needed, to each grammar rule. In the earlier two posts, […]

Accessing Azure BLOBs in Lisp

Recently I was looking for a Common Lisp library for accessing Azure services. Azure has official SDKs in many languages, but Lisp is not one of them. Quite understandable and I have no complaints. Because the services are all exposed via REST interfaces, it should not be difficult to implement a Lisp wrapper to use […]

Multi-value Return in C# 7.0

One of the nice language enhancements to C# in the latest release (7.0) is the ability to return multiple values from a function. Although one could use Tuples for this purpose, it is not an elegant or efficient approach. For more details, see this article. By the way, returning multiple values from a function is […]

Lisp: Returning Multiple Values From A Function

Written by on January 6, 2016 in LISP, Programming with 0 Comments

One of the interesting features of Lisp is its support for returning multiple values from a function, without bundling the values in a special container. Languages such as Python and Ruby support multi-value return (although there are subtle differences from Lisp). In C++11, we can use std::make_tuple() and std::tie(). To take an example, in Lisp, […]
