I'd like to say thank you to Chaitanya, who reached out to me and guided me through the outline; Pooja, who tirelessly edited my drafts; Divya, who meticulously reviewed the code; and everyone else from Packt who worked on this book and I haven't had a chance to meet. A huge thank you to Bram for reviewing this book. A word goes out to the Vim Japan conference organizers—Tatsuhiro Ujihisa (Uji), Taro Muraoka (KaoriYa), Thinca, Aomoriringo, Mopp, Yasuhiro Matsumoto (Mattn), t9md, and Guyon (and anyone else I missed). Thank you for your hospitality! Best regards to my supportive colleagues and cubicle mates at Google, and especially my manager, Patrick, who helped me balance writing this book with my career.
