Code Smell 277 - UPPERCASE Acronyms

Avoid Jumbled Acronyms for Clarity

TL;DR: Treat acronyms like normal words to improve human readability.

Problems

• Reduced readability
• Breaking naming style
• Words confusion
• Harder to pronounce

Solutions

1. Treat acronyms as Capitalized words

   \

2. 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.

AI Generation

Modern AI code generators may produce inconsistent acronym casing.

\ Always review and adjust their output to match your conventions.

AI Detection

With prompts, AI can fix these naming issues and suggest improvements based on the camelCase style.
