Prolog
Ever since I first learned Prolog, more than 20 years ago, it has been my
preferred programming language.
Why use Prolog?
Prolog is a tool for solving problems, rather than producing
"software products", and it will appeal to you if:
- You want your programs to be readable, and have a close correspondence with their specifications;
- Statements like
x = x + 1 offend your mathematical sensibility;
- You like to develop programs incrementally - with an interactive top-level, interactive debugging, and the ability to test (execute) program fragments independently;
- You want fewer lines of code and (therefore) fewer faults;
- You prefer to work with a handful of big ideas, rather than a lot of small ones;

Programming and the Internet. Prolog is unequalled as a language for
expressing queries and integrity constraints, and for processing text, which
make it an excellent choice for Internet applications.
- XML documents and Prolog terms have the same "tree" structure, which makes it easy to
program with XML and Prolog.
This free Prolog/XML translation code makes it
even easier.
- Recommended Prolog programming books.
- My solutions to some puzzles in Prolog:
Although Prolog is regarded as a niche language, it's a very versatile language.
I believe that the programming languages used in 2050 will owe more to Prolog
than to any other language.
