๐ŸŽฏ What We Did

๐Ÿ”ค This pass continued the steady progress of eliminating every abbreviated name from the Haskell codebase. ๐Ÿ“– The driving idea is unchanged: code should read like plain English, not a maze of cryptic short-form identifiers. ๐Ÿ—๏ธ This pass was structurally more significant than most โ€” it required creating a new sub-module to resolve naming conflicts before the field renames could proceed.

๐Ÿงฎ In total, this pass completed ten steps: eight record field renames across four data types, plus two more StaticComment field renames, all made possible by moving the Gql* types to a dedicated sub-module.

๐Ÿ“‹ The Ten Steps

โš™๏ธ Prerequisite โ€” Migrate Gql* types to Automation.StaticGiscus.GraphQL

๐Ÿ—๏ธ Before any of the remaining StaticGiscus field renames could proceed, a structural prerequisite had to be addressed. ๐Ÿ“ฆ The GqlComment record already had an author field, and GqlCommentsNode already had a nodes field. ๐Ÿšง Renaming StaticComment.scAuthor to author would create a collision with GqlComment.author in the same module, and renaming GqlDiscussionsPage.sgdpNodes to nodes would collide with GqlCommentsNode.nodes.

๐Ÿ”€ The solution follows the same pattern established by Automation.BlogComments.GraphQL earlier in the series: move all the Gql* types into a new sub-module called Automation.StaticGiscus.GraphQL, and import them qualified as Gql in the main module. ๐ŸŽฏ This keeps the accessor names unambiguous โ€” Gql.author, Gql.nodes, Gql.title โ€” while freeing up the unqualified namespace in the main module for StaticCommentโ€™s own fields.

1๏ธโƒฃ GqlPageInfo โ€” sgpEndCursor to endCursor

๐Ÿ“„ The GqlPageInfo record tracks pagination state for GitHubโ€™s GraphQL API. ๐Ÿ”‘ Its cursor field, which carries the opaque string identifying the current page boundary, was named sgpEndCursor โ€” where sgp stands for โ€œstatic Giscus page infoโ€. ๐Ÿ”ค Renamed to endCursor, directly matching the field name used in the GraphQL schema.

2๏ธโƒฃ GqlDiscussionsPage โ€” sgdpNodes to discussionNodes

๐Ÿ“‹ The GqlDiscussionsPage record wraps a page of GitHub Discussions with its items and pagination state. ๐Ÿ”ค The items field was named sgdpNodes, where sgdp stands for โ€œstatic Giscus discussions pageโ€. ๐Ÿšง Renaming it to nodes would conflict with the already-renamed GqlCommentsNode.nodes field โ€” both live in the same sub-module.

๐Ÿ“– Following the precedent from Automation.BlogComments.GraphQL, where GqlSearchNodes.gsnNodes was renamed to searchNodes rather than nodes to avoid a similar clash, this field was renamed discussionNodes. ๐ŸŽฏ The name is explicit: it tells the reader that these are discussion items, not generic nodes.

3๏ธโƒฃ GqlDiscussionsPage โ€” sgdpPageInfo to pageInfo

๐Ÿ”ข The pageInfo field on GqlDiscussionsPage held the pagination cursor and next-page flag. ๐Ÿ”ค It was named sgdpPageInfo, where sgdp is the same โ€œstatic Giscus discussions pageโ€ prefix. ๐Ÿ“– Renamed to pageInfo, which is both shorter and more meaningful โ€” it reads naturally in code like Gql.pageInfo page.

4๏ธโƒฃ GqlRepository โ€” sgrDiscussions to discussions

๐Ÿ—‚๏ธ The GqlRepository record represents a GitHub repository in the GraphQL response. ๐Ÿ”ค Its field for the discussions connection was named sgrDiscussions, where sgr stands for โ€œstatic Giscus repositoryโ€. ๐Ÿ“– Renamed to discussions โ€” no prefix needed when you can just write Gql.discussions repository.

5๏ธโƒฃ GqlData โ€” sgdRepository to repository

๐Ÿ“ฆ The GqlData record wraps the data field of a GraphQL response envelope. ๐Ÿ”ค Its inner repository field was named sgdRepository, where sgd stands for โ€œstatic Giscus dataโ€. ๐Ÿ“– Renamed to repository, matching the GraphQL field name directly.

6๏ธโƒฃ GqlError โ€” sgeMessage to message

โš ๏ธ The GqlError record carries a single error description from the GraphQL API. ๐Ÿ”ค That description was stored in sgeMessage, where sge stands for โ€œstatic Giscus errorโ€. ๐Ÿ“– Renamed to message โ€” which is exactly what it is, and what the JSON field is called.

7๏ธโƒฃ GqlResponse โ€” sgrData to responseData

๐Ÿ“ฌ The GqlResponse record is the top-level envelope for a GraphQL API response. ๐Ÿ”ค Its data field was named sgrData, where sgr stands for โ€œstatic Giscus responseโ€. ๐Ÿ“– Renamed to responseData, following the same convention used in Automation.BlogComments.GraphQL where the same pattern already appeared.

8๏ธโƒฃ GqlResponse โ€” sgrErrors to errors

โŒ The GqlResponse.sgrErrors field holds the optional list of errors returned alongside a GraphQL response. ๐Ÿ”ค The sgr prefix was stripped, giving the clean and self-descriptive name errors.

9๏ธโƒฃ StaticComment โ€” scAuthor to author

๐Ÿง‘ The StaticComment record represents a rendered Giscus comment ready for HTML injection. ๐Ÿ”ค The authorโ€™s display name was stored in scAuthor, where sc stands for โ€œstatic commentโ€. ๐Ÿ“– Renamed to author. ๐Ÿ›ก๏ธ Thanks to the sub-module migration, there is no longer any author accessor in scope from the Gql types โ€” Gql.author is qualified, so unqualified author unambiguously refers to StaticComment.author.

๐Ÿ”Ÿ StaticComment โ€” scAuthorUrl to authorUrl

๐Ÿ”— The authorโ€™s profile URL in StaticComment was stored in scAuthorUrl. ๐Ÿ”ค Renamed to authorUrl. ๐Ÿ This completes the first two of the four sc* field renames for StaticComment; the remaining two (scBodyHtml and scCreatedAt) will follow in a future pass.

๐Ÿ” Newly Discovered Abbreviations

๐Ÿ•ต๏ธ Scanning the codebase during this pass revealed no new abbreviations beyond what was already captured in the plan. ๐Ÿ“‹ The remaining items in the spec โ€” scBodyHtml, scCreatedAt, the local variables in StaticGiscus.hs, the bp* fields in BlogPosts.hs, and the fmLines/updatedFm bindings across several files โ€” are all accounted for in the plan.

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 devotes an entire chapter to naming โ€” arguing that the single most important act a programmer performs is choosing a name that reveals intent, which is exactly what each rename in this series does.
  • The Pragmatic Programmer by David Thomas and Andrew Hunt is relevant because it champions the โ€œdonโ€™t live with broken windowsโ€ philosophy, treating each cryptic abbreviation as a small broken window that accumulates into hard-to-read code.

โ†”๏ธ Contrasting

  • โœ…๐Ÿ’ป Code Complete by Steve McConnell takes a more tolerant stance on abbreviations, suggesting they are acceptable when they are standard, consistently applied, and documented โ€” a contrasting view to the zero-tolerance policy applied throughout this codebase.
  • Refactoring: Improving the Design of Existing Code by Martin Fowler is relevant because the rename-variable and rename-method refactorings described in detail there are precisely the mechanical operations being applied systematically in this series.
