A micro Lisp interpreter experiment

Posted on 21 June 2014 in Articles • Tagged with Python, Lisp, programming • 4 min read

While reading the Binary trees chapter from Programming Interviews Exposed by John Mongan et al. I started thinking of alternative recursion examples which do not involve sorting, generating Fibonacci sequence, binary tree traversal and similar tasks. Lisp! Lisp is inseparable from recursion and Lisp interpreter would be a good case to demonstrate what recursion is and how it can be used efficiently. What would be a minimal simplified Lisp interpreter written in Python? Surprisingly, I managed to do it just in 6 lines of Python code! And this is not just because of Python being a wonderful language, but because of Lisp being such a beautiful and simple concept.

PyRegs: The Python Regex Debugger

Posted on 22 May 2013 in Articles • Tagged with programming, Python • 1 min read

Long ago, I learned the regular expressions in order to write a simple syntax highlighting engine. Regular expressions are not hard to master, but take time to practice. Kodos was the regex debugger of my choice, as it was written in Python. All these years Kodos was a "must have" tool on my development machines. Suddenly with the new version of Debian operating system, Kodos was not in the repositories anymore! Why? Kodos is based on QT3 widgets toolkit, which is a bit outdated nowadays (QT5 has been released recently) and was removed from Debian 7.0 ("Wheezy"). That is how I decided to write a small Python regex debugger in Python 3 and its de-facto standard Tkinter bindings to the Tk GUI toolkit.
