TL;DR: Treat acronyms like normal words to improve human readability.
Problems
Reduced readability
Breaking naming style
Words confusion
Harder to pronounce
Solutions
Treat acronyms as Capitalized words
Use camelCase or snake_case
Context
Acronyms in uppercase (like JSON, XML, REST) in camel case break the natural reading flow.
You may think sendJSONRequestOnHTTPREST is a clear name, but it makes your code harder to read, especially when you string multiple acronyms together.
Treating acronyms like normal words in camelCase (sendJsonRequest) keeps your code more readable and easier to understand.
Sample Code
Wrong
class NetworkConnector {
func validateXMLFile() { /*...*/ }
func sendJSONRequest() { /*...*/ }
func parseURLResponse() { /*...*/ }
func setRESTAPIURL() { /*...*/ }
func retrieveHTTPStatusCode() { /*...*/ }
func updateDBConnection() { /*...*/ }
func configureSSLCertificate() { /*...*/ }
func setHTMLTemplate() { /*...*/ }
func generateUUID() { /*...*/ }
func connectViaFTP() { /*...*/ }
}
Right
class NetworkConnector {
func validateXmlFile() { /*...*/ }
func sendJsonRequest() { /*...*/ }
func parseUrlResponse() { /*...*/ }
func setRestApiUrl() { /*...*/ }
func retrieveHttpStatusCode() { /*...*/ }
func updateDbConnection() { /*...*/ }
func configureSslCertificate() { /*...*/ }
func setHtmlTemplate() { /*...*/ }
func generateUuid() { /*...*/ }
func connectViaFtp() { /*...*/ }
}
Detection
[X] Semi-Automatic
It would help if you had a smart thesaurus.
To detect this smell, look for methods or variable names with uppercase acronyms that disrupt readability.
Code reviewers or linters can also flag camelCase inconsistencies.
