Yu Sheng is a Chinese author of technical books. Public information about him is limited, and his nationality, dates of birth and death, and educational background are not known. One of his works is held in the collection: Regular Expressions Guide (2nd Edition), a book commonly classified under programming and design. Judging from the subject, he focuses on regular expressions, a practical technology widely used in text processing and software development. His writing tends toward reference and learning guides, emphasizing conceptual clarity and rule explanation rather than general programming philosophy. The existence of a second edition indicates that the book has been revised and updated, suggesting continued relevance and reader demand. For readers who want to learn regular expressions systematically, such a work can serve as a reference for consultation and practice. Because no other information about the author is publicly available, a fuller picture of his work still requires more material.
