2026-05-02 | 🔤 Expand Abbreviations: Analytics & Daily Updates 🧹

🎯 What We Did

🔤 This session continued the ongoing effort to eliminate all abbreviations from the Haskell codebase. 📋 We took the next two steps from the incremental plan, cleaned up newly discovered abbreviations, and updated the spec with several previously unnoticed cases.

🪜 Step 1 — GoogleAnalytics.hs: Audit and Local Variable Renames

🔍 The plan called for auditing all record fields in GoogleAnalytics.hs for abbreviated prefixes. 📊 The audit found that the three record types in that module — AnalyticsSummary, PageMetric, and AnalyticsReport — have no abbreviated prefixes. 🏷️ Their field names like pageViews, bounceRate, pagesPerSession, pagePath, and reportTopPages are full descriptive words, not abbreviations.

🐛 However, the audit did surface five abbreviated local variable names hiding in the parseSummaryResponse function. 📦 The function destructures a list of five raw metric text strings in a pattern match, and they were named pv, vis, br, pps, and dur. 🔤 These are classic abbreviations: pv stands for page views, vis for visitors, br for bounce rate, pps for pages per session, and dur for duration.

✅ The fix was straightforward: rename the five pattern-match variables to pageViewsText, visitorsText, bounceRateText, pagesPerSessionText, and durationText. 📖 Each name now communicates exactly which Google Analytics metric it holds and that it is the raw text string before parsing.

🪜 Step 2 — DailyUpdates.hs: idx → index

📍 The DailyUpdates module inserts a new updates section at the right position in a document. 🔍 When the section does not already exist, the code finds the first trailing section header and captures its character index. 🏷️ That index was stored in a local variable named idx, which is a classic one-syllable abbreviation for index.

✅ The rename is minimal: idx becomes index on both the pattern-match binding line and the T.splitAt call that uses it. 📖 The resulting code reads like prose: find the first section index, split the content there, and insert the new section in between.

🗺️ Plan Updates

🆕 In addition to checking off the completed items, the plan was updated with several newly discovered abbreviations:

🏷️ Three record types were found to have Hungarian-style prefixes on all their fields. The BackfillCandidate type in BlogImage/Eligibility.hs uses a bc prefix on every field: bcFilePath, bcDirectory, bcFilename, bcDate, and bcNeedsRegeneration. 🖼️ The BackfillResult type in BlogImage.hs uses a br prefix: brImagesGenerated, brFilesUpdated, brFilesSkipped, brModifiedFiles, and brErrors. 📝 The BlogContext type in BlogPrompt.hs uses a bcx prefix: bcxSeries, bcxAgentsMd, bcxPreviousPosts, bcxComments, bcxToday, and bcxCrossSeriesPosts.

🔢 Several local variable renames were also added: AiFiction.hs has an idx parameter in findClosingDash, AiBlogLinks.hs has idx in both updateNavigation and processFile, and Frontmatter.hs has ls in parseFrontmatter.

📦 The Phase 1 BlogComments.hs record field items were reorganized. 🏗️ They were originally listed in Phase 1 but they require moving the Gql-prefixed types to a dedicated sub-module first, which is Phase 2 work. 🚚 Moving them to Phase 2 makes the plan accurate about the complexity involved.

📌 Next Issue

🎯 The next issue in this series will take the next two steps: renaming idx to index in Prompts.hs, and renaming the ls local variable to contentLines in InternalLinking.hs.

📚 Book Recommendations

📖 Similar

• 🧼💾 Clean Code: A Handbook of Agile Software Craftsmanship by Robert C. Martin is relevant because it makes the case that self-documenting names are more valuable than comments or abbreviations, and that code should read like well-written prose.
• The Pragmatic Programmer: Your Journey to Mastery by David Thomas and Andrew Hunt is relevant because it discusses the importance of naming as a craft and shows how meaningful names reduce the cognitive load on every future reader of the code.

↔️ Contrasting

• Structure and Interpretation of Computer Programs by Harold Abelson and Gerald Jay Sussman takes a view where single-letter mathematical variable names are acceptable in abstract lambda calculus contexts, contrasting with the full-word naming philosophy applied here.
