Acknowledgments

Unusual as it may seem, I’d like to start with a self-acknowledgment. I had no idea that I could keep myself focused for so long on a specific topic of interest. The process of writing this book taught me the values of perseverance, self-determination, and self-belief.

Thanks to my team at Anshinsoft for creating a workplace where ideas are nurtured and given wings to fly. The late-night brainstorming sessions helped me to carve out many a complex domain model and ignited in me a love of DSLs.

Thanks to our client manager, Watanabe san (Mr. Tohru Watanabe), who taught me the domain model of the securities trading business. This book is filled with examples of what he’s taught me over the many years that we’ve interacted.

Thanks to the following reviewers for helping me improve the quality of the manuscript: Sivakumar Thyagarajan, Darren Neimke, Philipp K. Janert, James Hatheway, Kenneth DeLong, Edmon Begolli, Celso Gonzalez, Jason Jung, Andrew Cooke, Boris Lenzinger, David Dossot, Federico Tomassetti, Greg Donald, John S. Griffin, Sumit Pal, and Rick Wagner. Special thanks to reviewers Guillaume Laforge and John Wilson for teaching me nuances of writing Groovy DSLs; Michael Fogus for his suggestions on improving the contents of chapters 5 and 6; and Sven Efftinge for his suggestions on Xtext and external DSLs in chapter 7. And to Franco Lombardo for doing a final technical proofread of the manuscript shortly before it went to press.
