LPL-1

Here’s the last of the oddball Little Programming Languages (for now). This one is a little like LPL-2 in using a three-part syntax (which turns out to be non-ideal). Unlike LPL-3, neither of these are particularly usable languages — more along the lines of being something a language designer amused himself with on a rainy afternoon.

A key goal in LPL-1 was to minimize the use of punctuation characters. No brackets or parenthesis to create syntax blocks. (Square brackets for array indexing and parentheses for expressions, but that’s it.)

The language I showed you last time, in LPL-3, was a fairly reasonable one. This time I’m showing you a preposterous one no one would actually use. Worse, it turns out to be something of a failure due to weird holes left by the design goal of orthogonal single-syntax construction.

But that oddness helps us focus on what a programming language actually is, so it’s worth a peek. And maybe it’ll give you a laugh.

I’ll pick up with the language I began describing last time in a future post. Right now I want to pick up the thread of Little Programming Languages (LPLs) and use several examples to illustrate what underlies a programming language. (And as it turns out, these are “little” only in a certain sense.)

This first example, LPL-3, is Lisp-like and, because of that, is fairly orthogonal. Even better, it’s probably actually usable, although — like Lisp — it doesn’t have the cleanest syntax (languages like Python have really spoiled me).

One characteristic of the hard-core coder is a love of computer languages, programming languages in particular. Programmers of that ilk — of my ilk — collect new languages like merit badges. (I get a kick out of saying that I’ve programmed “from Ada to the Z-80!”)

The especially far gone of us also enjoy creating new languages (or in some cases, new dialects of XML). Lately I’ve been playing with a language design that follows a favorite theme: the single-syntax construction language.

Too much specialization!

To make this blog (I hope) useful, I have tips and advice and bits of advice. But the initial motivation was wanting to write about programming or software in general — topics too technical for my regular blog. In particular, I wanted a place to document past projects, ideas and personal (but sharable) thoughts about coding. I wanted a place to tell stories.

Today I have a story to tell about a programming project I’m working on.
