Waldemar Celes is a Brazilian computer scientist and one of the core designers of the Lua programming language. Publicly available information about him is currently limited, and Chinese readers mainly know him through Lua, which he developed together with Roberto Ierusalimschy and Luiz Henrique de Figueiredo. The catalog includes his work Lua 5.4 Reference Manual (Chinese edition), categorized under computing and software learning. The book is the official reference documentation for Lua 5.4, systematically explaining the language's syntax, standard library, and C API, making it an important resource for learning and consulting Lua. Its text is definition-oriented, clearly structured, and precise in terminology, suitable for developers, script writers, and embedded-systems engineers. As a representative document of a lightweight scripting language, it reflects Lua's concise, embeddable design and has reference value for the Chinese technical community.
