A golang package to convert normal CamelCase to Golang's CamelCase and vice versa.

go get -u github.com/takuoki/gocase

str := gocase.To("IpAddress") // "IPAddress"

str := gocase.To("defaultDNSServer") // "defaultDnsServer"

converter, _ := gocase.New(gocase.WithInitialisms("JSON", "CSV"))

str1 := converter.To("IpAddress") // "IpAddress" (no convert)
str2 := converter.To("JsonFile")  // "JSONFile"
str3 := converter.To("CsvFile")   // "CSVFile"

The default converter converts as follows

• To: converts a string from From to To.
• Revert: converts a string from To to From.

Note that it is impossible to accurately determine the word break in a string of consecutive uppercase words, so the string converted with To and Revert may not match the original string.

example

• IdB --To-> IDB --Revert-> IDb
• UUid --To-> UUID --Revert-> Uuid

For more details, please see initialisms section in Staticcheck.
