About Me

PBX My name is Paul Bissex, and e-scribe.com is my consulting business. I build web applications using as much open source software as possible. From September to June I teach web design and other important non-photographic professional skills to photographers. In the '90s I wrote technology commentary and reviews for magazines, newspapers, and web publications, including Wired, Salon.com, FamilyPC, the late lamented Web Review, and the Chicago Tribune. Feel free to email me.

Book

I'm co-author of "Python Web Development with Django", an excellent guide to my favorite web framework. Its strong points include an introduction to Python, and better coverage of Django 1.0 than nearly anybody else. Published by Addison-Wesley, it is available from Amazon and your favorite technical bookstore as well.

The whitespace brigade

Syntactically significant whitespace is one of those debating points frequently raised in unproductive language thrashes involving Python. One persistent implication made by SSW-haters is that it's a freakish mutation unique to Python. Or, if they're feeling particularly vicious, they'll bring up Fortran. Cold comfort.

In fact, there are quite a few other languages that have gone down this path. Flipping through a big fat book that I bought because Steve Yegge recommended it, I came across mention of a couple that were new to me. Then I went digging for more. Here's an incomplete list:

In the beginning (1966) there was ISWIM, which was never implemented but was apparently the first language to cast off Algol's semicolons
The ABC language, which famously influenced Python creator Guido van Rossum
Miranda
Occam
Various edge cases: the "whitespace thing" for OCaml, the markup language YAML, the Python-derived Boo, the eponymous Whitespace language.
Haskell, perhaps not coincidentally my new self-study project
And of course, the poster child, Python itself.

In my searches I came across the term "off-side-rule languages", which I hadn't heard before, though apparently some people use it. I think it's a clunker. And "syntactically significant whitespace" is too much of a mouthful, and imprecise to boot (after all, whitespace between tokens is fairly significant!).

I think the field is open for a zippy marketing term. How about Spacejax? Space 2.0? Hmm, this is harder than I thought...

new buzz words are hard to come up with, but one of the rules is that you can't reuse parts of other terms. (i.e. spacejax => space + 'ajax'[1:]). It's often common to create an acronym (i.e. ajax). That said, i nominate LUSS => 'Languages Using Significant Spacing'

I don't know how you gathered your data, but neither SML nor OCaml have any more significant whitespace than a language like C. So listing "ML" as a whitespace-signficant language is wrong.

Not sure how ML ended up in there; I've removed it. Thanks for the heads-up.

As for "the whitespace thing for OCaml", try following the link!
