Why read source code? How to start? What I learned?
Anything interesting?
Why read source code ?
Ian Ruotsala
http://blog.rubybestpractices.com/posts/gregory/005-code-reading-stdlib.html “once you start digging around in someone else’s code
base, you’ll learn a lot about your own strengths and weaknesses” - Ruby Best Practice
See how the Core Team write Ruby

Contribution!
Committer in my dream!

Requirement ?
C language
“What if I don’t have any skill of C?”
“Just Learn It!”
Curiosity and Passion
Where to Start ?
get source files!
download from Ruby website, or clone from github
Ruby 1.9.2 p290
None
Quick browsing.. :)
* .c + * .h * .rb (stdlib)
Let’s have some fun!
Object Class String Array Hash
“ruby.h”
Object => RObject Class => RClass String => RString Array
=> RArray Hash => RHash
“object.c”
Init_XXXX( )
“all Class’s class is a Class”
“new”
class A def initialize puts "hello" end end a =
A.new
Proc
How to execute a Proc?
proc.call proc[ ] proc.yield proc === 123
attributes
push v.s. <<
Object ID
What else?
Haskell-like syntax :)
head (x:_) = x tail (_:xs) = xs
people = { "Eddie" => ["green", "
[email protected]
"], "Joanne" => ["yellow",
"
[email protected]
"] } people.map { |name, (color, email)| puts [name, email] }
parse.y#8277-8299 shadowing_lvar_gen( ) people = { "Eddie" => ["green", "
[email protected]
"],
"Joanne" => ["yellow", "
[email protected]
"] } people.map { |name, (_, email)| puts [name, email] }
Method missing
Anything interesting ?
Interesting naming.. XD
Conclusion
“from basic structure”
“don’t be afraid of source code”
