About

… a naming-convention library for the Go programming language. The two categories are delimiter-separated and letter case-separated words. Each of the formatting functions support both techniques for input, without any context.

This is free and unencumbered software released into the public domain.

Inspiration

• name.CamelCase("pascal case", true) returns “PascalCase”
• name.CamelCase("snake_to_camel AND CamelToCamel?", false) returns “snakeToCamelANDCamelToCamel”
• name.Delimit("* All Hype is aGoodThing (TM)", '-') returns “all-hype-is-a-good-thing-TM”
• name.DotSeparated("WebCrawler#socketTimeout") returns “web.crawler.socket.timeout”
