๐ŸŽฏ What We Did

๐Ÿ”ค This pass continued the steady work to remove every abbreviated name from the Haskell codebase. ๐Ÿ“– The goal is always the same: code that reads like a clear explanation, not a series of cryptic shorthand. ๐Ÿงฎ In this pass, we completed exactly ten steps spanning two source files โ€” one in the internal-linking masking module and nine in the static Giscus comments module.

๐Ÿ“‹ The Ten Steps

1๏ธโƒฃ InternalLinking/Masking.hs โ€” fmBlock to frontmatterBlock

๐Ÿ”— The maskFrontmatter function builds a local block of text representing the full frontmatter delimiters and content, then measures its length to replace it with blank spaces. ๐Ÿ“„ This block was named fmBlock, where fm is an abbreviation for frontmatter. ๐Ÿ”ค It was renamed to frontmatterBlock to spell out what it actually is.

2๏ธโƒฃ StaticGiscus.hs โ€” sgaLogin to login (GqlAuthor)

๐Ÿง‘ The GqlAuthor record held the GitHub login handle in a field named sgaLogin, where sga stands for โ€œstatic Giscus authorโ€. ๐Ÿ”ค The prefix is redundant โ€” the module qualifier and the record type already provide the context. ๐Ÿ“– The field was renamed to login.

3๏ธโƒฃ StaticGiscus.hs โ€” sgaUrl to url (GqlAuthor)

๐Ÿ”— The profile URL for a Giscus comment author was stored in sgaUrl. ๐Ÿ”ค The sga prefix was stripped, leaving the plain and descriptive url.

4๏ธโƒฃ StaticGiscus.hs โ€” sgcBodyHtml to bodyHtml (GqlComment)

๐Ÿ’ฌ The HTML body content of a GraphQL comment was stored in sgcBodyHtml, where sgc stands for โ€œstatic Giscus commentโ€. ๐Ÿ”ค Renamed to bodyHtml โ€” the type and context already make clear it belongs to a comment.

5๏ธโƒฃ StaticGiscus.hs โ€” sgcAuthor to author (GqlComment)

๐Ÿง‘ The author field on GqlComment had the redundant sgc prefix. ๐Ÿ”ค Renamed to author. ๐Ÿ›ก๏ธ Because the author and login field names could shadow each other in the mkGqlComment test helper, the helperโ€™s parameter was renamed from login to username to avoid the shadowing.

6๏ธโƒฃ StaticGiscus.hs โ€” sgcCreatedAt to createdAt (GqlComment)

๐Ÿ• The creation timestamp on a GqlComment was stored in sgcCreatedAt. ๐Ÿ”ค Renamed to createdAt โ€” standard and unambiguous.

7๏ธโƒฃ StaticGiscus.hs โ€” sgcnNodes to nodes (GqlCommentsNode)

๐Ÿ“‹ The GqlCommentsNode wrapper held its list of comments in a field called sgcnNodes, where sgcn stands for โ€œstatic Giscus comments nodeโ€. ๐Ÿ”ค Renamed to nodes, matching the GraphQL vocabulary it directly represents. ๐Ÿ”€ In buildCommentsMap, the local variable that had also been named comments was renamed to staticComments to avoid a recursive binding conflict with the newly renamed comments accessor on GqlDiscussion.

8๏ธโƒฃ StaticGiscus.hs โ€” sgdTitle to title (GqlDiscussion)

๐Ÿ“ The GqlDiscussion record stores the discussion title in sgdTitle, where sgd stands for โ€œstatic Giscus discussionโ€. ๐Ÿ”ค Renamed to title. ๐Ÿ›ก๏ธ The mkDiscussion test helperโ€™s parameter was renamed from title to discussionTitle to avoid shadowing the new record field accessor.

9๏ธโƒฃ StaticGiscus.hs โ€” sgdComments to comments (GqlDiscussion)

๐Ÿ’ฌ The nested GqlCommentsNode on a GqlDiscussion was stored in sgdComments. ๐Ÿ”ค Renamed to comments. ๐Ÿ›ก๏ธ The mkDiscussion test helperโ€™s parameter was renamed from comments to discussionComments for the same shadowing reason.

๐Ÿ”Ÿ StaticGiscus.hs โ€” sgpHasNextPage to hasNextPage (GqlPageInfo)

๐Ÿ“„ The GqlPageInfo record tracks pagination state, including a boolean that says whether more pages exist. ๐Ÿ”ค This was stored in sgpHasNextPage, where sgp stands for โ€œstatic Giscus page infoโ€. ๐Ÿ“– Renamed to hasNextPage, which directly mirrors the GraphQL field name and makes the pagination logic easy to read.

๐Ÿ” Newly Discovered Abbreviations

๐Ÿ•ต๏ธ Reviewing the StaticGiscus.hs source during this pass revealed several more abbreviated names that are not yet in the plan:

  • ๐Ÿ”ข idx in injectStaticComments should become insertionPoint โ€” it holds the character index where static comments should be inserted before the giscus div
  • ๐Ÿ”„ mAfter in fetchAllDiscussions should become maybeAfterCursor โ€” it holds an optional pagination cursor
  • ๐Ÿ—‚๏ธ mPage in fetchAllDiscussions should become maybePage โ€” it holds an optional page result
  • ๐Ÿ“ฆ acc in fetchAllDiscussions should become accumulatedDiscussions โ€” it is the accumulator for all fetched discussions across pages
  • โž• newAcc in fetchAllDiscussions should become updatedDiscussions โ€” it is the updated accumulator after appending a new page

๐Ÿ—’๏ธ All five have been added to the spec for future passes.

โœ… Results

๐ŸŸข All 2031 tests passed after the changes. ๐Ÿงน HLint reported zero hints. ๐Ÿš€ The build compiled cleanly with no warnings under the -Wall -Werror flags that CI enforces.

๐Ÿ“š Book Recommendations

๐Ÿ“– Similar

  • ๐Ÿงผ๐Ÿ’พ Clean Code: A Handbook of Agile Software Craftsmanship by Robert C. Martin is relevant because it argues that the names we choose are the primary communication channel between code and its readers โ€” every renamed field in this pass is an act of choosing a better name.
  • The Pragmatic Programmer by David Thomas and Andrew Hunt is relevant because it explicitly advises against cryptic abbreviations and champions code that reveals intent, making it a natural companion to this ongoing rename series.

โ†”๏ธ Contrasting

  • โœ…๐Ÿ’ป Code Complete by Steve McConnell offers a more pragmatic stance where abbreviations are acceptable if consistently applied and documented โ€” a counterpoint to the strict zero-tolerance approach taken throughout this codebase.
  • Haskell Programming from First Principles by Christopher Allen and Julie Moronuki is relevant because it teaches Haskell with meticulous attention to naming and abstraction, reinforcing the idea that clear names are especially important in a language where types carry so much expressive weight.
