At last, a guide that makes creating a language with its associated
baggage of lexers, parsers and compilers, accessible to mere mortals,
rather to a group of a few hardcore eclectics as it stood until now.
The first thing that catches the eye, is the subtitle:
The unix philosophy applied to language design, for GPLs and DSLs"
What is meant by "unix philosophy" ?. It's taking simple,
high quality components and combining them together in smart ways to
obtain a complex result; the exact approach the book adopts.
I'm getting ahead here, but a first sample of this philosophy becomes
apparent at the beginnings of Chapter 5 where the Parser treats and
calls the Lexer like unix's pipes as in lexer|parser. Until the end of
the book, this pipeline is going to become larger, like a chain, due to
the amount of components that end up interacting together.
The book opens by putting things into perspective in Chapter 1: Motivation: why do you want to build lan…
Given our expectations of Xbox games, you might consider writing a
game within a 13K limit, which is the challenge for the annual js13K
competition far too restrictive. Its results are now out and prove that
it is possible to produce a game that is fun to play.
Back in the tape loading days and on platforms the likes of
Commodore64 games came in sizes of 4K or less. As proof of concept,
here's a list of a few such 4K titles, copied over from Lemon64 's archive: Alien SidestepBug CrusherDot GobblerClose EncountersDot Gobbler v2GridrunnerLaser CyclesMarios BrewerySpace ActionSpace RicoshayTank WarsHesmon64Retro Ball
making all sorts of applications or games available to everyone through
the medium of the browser, rendering the need of dedicated platforms
and Operating systems obsolete, 13K is sufficient enough to pack both
gameplay AND cool graphics due to the advanced browser engines and
t's the time of year when the world-class Hour of Code once more commences; just an hour for introducing coding to the uninitiated, having them complete self guided tutorials. But is a hour sufficient? What can a beginner actually code within this limit? The answer is a bit more complicated than that, so let's find out all about it!
Integrated into the larger, worldwide, annual Computer Science Education week, this year taking place December 4-10, Hour of Code's novel mission has always been to get everybody coding, aged from 4 to 104, by providing: "a one-hour introduction to computer science, designed to demystify code, showing that anybody can learn the basics, and broadening participation in the field of computer science".
But first of all, why this obsession with Computer Science, in particular in getting kids as young as 4 to learn to code? The answer is simple. Nowadays code is everywhere around us, from desktop computers to mobile phones and, thanks to w…
