2026-05-02 | 🔤 Expand Abbreviations: TokenResponse and ServiceAccountKey Fields 🧹

🎯 What We Did

🔤 This session continued the ongoing series of abbreviation expansions in the Haskell codebase. 🗂️ We tackled two record types in the GcpAuth module — removing the Hungarian-notation prefixes from all their fields so the code reads like natural English.

📋 Step 1 — TokenResponse Fields

🏷️ The TokenResponse record previously used the prefix “tr” on every field name. 📖 This meant reading code like “trAccessToken tokenResp” instead of the clearer “accessToken tokenResp”. 🔄 We renamed three fields in a single step:

🔑 The field previously called trAccessToken is now accessToken. 🪪 The field previously called trTokenType is now tokenType. ⏱️ The field previously called trExpiresIn is now expiresIn.

🔧 The only call site outside the record definition itself was a single line in the getAccessTokenWithScope function that extracts the access token from a successful response. That line was updated to use the new name.

📋 Step 2 — ServiceAccountKey Fields

🏷️ The ServiceAccountKey record used a “sak” prefix on all three of its fields. 🌐 Since this type is exported and used across multiple files — GcpAuth.hs itself, the GcpAuthTest.hs test file, and TaskRunners.hs — we had to update all three locations. 🔄 The three renames were:

🗂️ The field previously called sakProjectId is now projectId. 📧 The field previously called sakClientEmail is now clientEmail. 🔐 The field previously called sakPrivateKey is now privateKey.

🧪 The test file previously accessed sakProjectId and sakClientEmail to assert their values after parsing a JSON string. Both assertions were updated to the new names. 📋 The TaskRunners module logs the client email when starting the daily analytics task. That log line was updated from GcpAuth.sakClientEmail to GcpAuth.clientEmail.

✅ Results

🏗️ The build succeeded with no compiler warnings. 🧪 All 2031 tests passed. 🧹 HLint reported zero hints. ✅ The six spec checklist items were marked complete.

📚 Book Recommendations

📖 Similar

  • 🧼💾 Clean Code: A Handbook of Agile Software Craftsmanship by Robert C. Martin is relevant because it advocates naming variables with full, descriptive words so that code reads like prose — exactly the principle motivating this abbreviation-expansion project.
  • The Pragmatic Programmer by Andrew Hunt and David Thomas is relevant because it emphasizes writing code that communicates intent clearly, and discourages obscure abbreviations that force the reader to maintain a mental decoding table.

↔️ Contrasting

  • ✅💻 Code Complete by Steve McConnell offers guidance that sometimes shorter names are acceptable in very local scopes, contrasting with the strict no-abbreviations policy applied uniformly here regardless of scope.
  • Types and Programming Languages by Benjamin C. Pierce is relevant because strong static types — like Haskell’s record types — are what make these large-scale renames safe and mechanical: the compiler catches every missed call site.
