  • i had a dream…

    June 12, 2009

    Kernel

    The kernel would be a microkernel, with everything from the drivers, to [...]

  • Rubygame 3 on Ruby 1.9

    3. mkdir src

    7. cd ruby-1.9.0-1
    8. ./configure –prefix=/home/user/ruby19
    9. make
    10. make install
    Now you can switch to this sandbox at any time by executing ‘export PATH=/home/user/ruby19/bin:$PATH’ in a shell.

  • The Classy Struct

    August 8, 2006

    So what exactly is the difference between a class and a struct in C++? After wondering and debating internally for quite a long time, I looked around the net and found the (simple) explanation that:
    "The only difference between a struct and a class is in the default access."
    That is, a sruct is public by default [...]

  • Building an “include” graph

    August 6, 2006

    How easy would it be to build include graphs in ruby?
    Here's my first attempt:
    PLAIN TEXT
    RUBY:

    $list_of_files = Hash.new

    $list_of_files.each {|node|

    node = Array.new

    }

    def store_includes(pathname)

    lines = IO.readlines(pathname)

    lines.each {|line|

    if line.include? "#include"

    include_file = line[line.index("#include")+"#include".size,line.size]

    fidx = 0

    sidx = 0

     

    if include_file.include?("\"")

    fidx = include_file.index("\"") + 1

    sidx = include_file.index("\"",fidx+1) - 1

    end

     

    if include_file.include?('<')

    fidx = include_file.index('<') + 1

    sidx = include_file.index('>') - 1

    end

     

    include_file = include_file[fidx..sidx]

    $list_of_files[pathname].add(include_file)

    end

    }

    end

     

    def iterate_files(pathname)

    list = [] [...]

  • File extensions in ruby

    August 6, 2006

    Is there a more efficient way to extract the file extensions in ruby? I currently do the following.
    PLAIN TEXT
    RUBY:

    ext = File.basename(filepath).reverse.split('.')[0].reverse
