いまさらながらオライリーのepubが600円均一祭りな件に気づいたのでメモ

買い物

iPhoneのO'ReillyアプリはDRMフリーでepubが格納されていて、簡単に抽出できる…らしい。


404 Blog Not Found:perl - O'ReillyのiPhoneアプリ本からepubをぶっこぬく

とりあえずいくつか買ってみてテスト

  • The Ruby Programming Language
  • Best of TOC
  • Natural Language Processing with Python
  • Beautiful Testing
  • Hadoop: The Definitive Guide

こんな感じに

うまく見れるようだ

見出しもOK

perlの抽出スクリプトは存在していたけど、環境を汚すのがイヤだったのでPythonで適当に。

#!-*- coding:utf-8 -*-

import sys
import os
import re
import zipfile

if __name__ == "__main__":
    if len(sys.argv) < 2:
        print "Usage: # python oipa2epub.py filename"
        sys.exit(1)
    filename = sys.argv[1]
    if not filename.endswith(".ipa"):
        print "%s is not supported file!" % filename
        sys.exit(1)
    filename = os.path.splitext(filename)[0]
    z    = zipfile.ZipFile( filename + ".ipa", 'r' )
    newz = zipfile.ZipFile( filename + ".epub", 'w', zipfile.ZIP_DEFLATED )
    p = re.compile("^Payload/[^/]+/book/(.+)")
    for (item, info) in zip(z.namelist(), z.infolist()):
        if not p.search(item):
            continue
        info.filename = p.sub(r"\1", info.filename)
        newz.writestr(info, z.read(item))
    z.close()
    newz.close()

…さて、気がつけばiTunes残高が10円。買いすぎには注意しましょうー
