Ask for a field per line in a record value A new module rule, `HsRecordFieldPerLine`. ## Why Changing one field of a record written on one line rewrites that line, so the diff says the whole value changed and review has to read it to find out what did. Adding a field reflows whatever followed it. A field per line makes each of those a one-line diff. A value with one field has nothing to line up against and no second field to push around, so it is left alone. ## What it reads The fact is the offending value rather than every record value. What it records is the line each field starts on, not the expression's own span: a field whose value runs onto a second line makes the expression multi-line while every field still has a line of its own, and that is not what the rule is about. The `..` of a wildcard stands where a field would, so it takes up a line the same way. Both `RecordCon` and `RecordUpd` are read, and both update forms. Record patterns are not record values and are left alone. ## The two commits 1. The rule: the check, the registry entry, the good and bad resources. 2. This repository written to keep it. The flake runs hopinion on hopinion, so a rule that ships is one this repository keeps. Layout only, 19 files. `nix flake check` passes.
