The Internet Engineering Task Force (IETF) has published RFC 3092, which provides a detailed exploration of the terms ‘foo’, ‘bar’, and ‘foobar’ as metasyntactic variables. This document addresses the lack of proper explanation surrounding these terms, which have appeared in approximately 212 RFCs, or about 7% of all RFCs issued to date.
Clarifying Metasyntactic Variables
These terms are often used in programming examples without adequate context, leading to confusion, particularly for non-native English speakers. RFC 3092 aims to rectify this by offering definitions and a historical overview of these words. The document notes that ‘foo’ is frequently the first variable in examples, followed by ‘bar’, and that ‘foobar’ is a common combination of the two.
Historical Context and Evolution
The origins of ‘foo’ can be traced back to various cultural references, including comic strips and military slang. The term gained popularity in the 1930s through the comic strip ‘Smokey Stover’, where it was used in nonsensical phrases. The document also discusses the term’s evolution during World War II, where ‘foo fighters’ referred to unidentified flying objects, showcasing the term’s adaptability and integration into different contexts.
Acronyms and Technical Usage
RFC 3092 also delves into the acronyms associated with ‘foo’ and ‘bar’, such as FUBAR, which has military origins. The document lists various technical meanings, including ‘FTP Operation Over Big Address Records’ for FOOBAR, further illustrating the term’s relevance in computing. This multifaceted nature of ‘foo’ and its derivatives highlights their significance in both technical and cultural lexicons.
Implications for Newcomers and the Community
By providing a comprehensive overview of these terms, RFC 3092 serves as a valuable resource for newcomers to the programming community. Understanding the etymology and usage of ‘foo’, ‘bar’, and ‘foobar’ can enhance clarity in technical discussions and documentation, ultimately fostering a more inclusive environment for learning and collaboration.
