your sword is glowing with a faint blue glow

I dabbled in Interactive Fiction, aka Text Adventures, long ago —- I played Adventure on my Apple ][ and Dungeon/Zork on a VAX; I wrote a primitive game in BASIC and later in college partially implemented a language for building games in yacc; and then after graduating, my first serious Mac program was a souped-up and nearly finished version of that language. After that I was too busy with “real” jobs, but others kept the flame alive even after Infocom tanked, building their own adventure-design languages like TADS and Inform and spawning a cult scene of increasing complexity and literary merit. I kicked the tires of TADS and Inform a few years back, then got distracted by other shiny things. You know how it is.

Anyway: now I turn around and there’s Inform 7, a thing of splendor beyond my dreams. Not only does it have an IDE with a really interesting form of integration testing, but the syntax itself has become an ambitious attempt at natural language. I haven’t started coding yet — I have a dreamlike apprehension that the whole concept will melt like cotton-candy if I touch it — but as an example here is an unmodified section of the source code of a real game that I’ve just been playing:

Section 2 - Smells

A thing has a property called scent. The scent of a thing is usually “nothing”.

A procedural rule: ignore the block smelling rule.

Carry out smelling something:
say “From [the noun] you smell [scent of the noun].”

Instead of smelling a room:
if a scented thing can be touched by the player, say “You smell
[the list of scented things which can be touched by the player].”;
otherwise say “The place is blissfully odorless.”

Definition: a thing is scented if the scent of it is not “nothing”.

Before printing the name of something scented while smelling a room: say “[scent] from the ”

Now that’s wild!
