The Tao gave birth to machine language

Machine language gave birth to the assembler


The assembler gave birth to the compiler

Now there are ten thousand languages


Each language has its purpose, however humble

Each language expresses the Yin and Yang of software

Each language has its place within the Tao


But do not program in COBOL if you can avoid it




Greenspun's Tenth Rule of Programming


General purpose languages

Special purpose languages

Domain specific languages


Where are we now?


Java



“Scripting” languages


“Scripting” languagesPragmatic languages


Where did we come from?


Ruby lineage


a, b, c = 42, 69, 25


def foo yield 42 3.times do |n| yield n*25 endend

foo { |x| puts x }


CLU


/^(\d{3})-(\d{4})$/ =~ phone_number


$x = 42@me = other@@foo += 2


Global swearing

$/ = “%”$= = trueputs $!


puts “hello” unless moon == :full


Perl


class MyNumber < Number; end


foo.send :answer?, 42


puts obj.methods.grep /=$/


Smalltalk


class Foo include ExampleMethodsend

baz.extend ExampleMethods


Lisp Machine Lisp


def incrementor(x) lambda do next, x = x, x+1 next endend

i = incrementor(10)i.call # => 10i.call # => 11i.call # => 12


Scheme


Ruby


Good design is not innovation

Good design is choosing what to include - and what to not include



Imperative programming


Functional programming


Logic programming


Object oriented programming


Domain specific languages


Multiparadigm languages


Ceremony vs Essence


Typing



Natural languages?



Design


Communication


Abstraction


Expressiveness


First class


Focused or multiparadigm?


Where are we going?


Is concurrency really a large problem?



More programming languages - not fewer


Language leverage



Higher level


Slowness and wastefulness


Virtual machines


Text based languages?


AST languages?


Language workbenches


NBL?


Other paradigms?




It’s going to be interesting


Where is Ruby going?


Ruby 2.0


I don’t know


Easier to modify the language


Canonical AST


Simplify the core?


Scoped extensions


DSLs


Concurrency?


Typing?


RubyX
