- Fix bug in BackendUtil/lowest level of brittany about
alignment being ignored after a comment,
- Properly layout large (more than single-line) types in
record fields and in data decl rhs arguments,
- Properly layout data decl constructors with large "heads"
(forall, constraints),
- Add a config flag to control single-line layout of record
definition,
Simple records are supports. The tests cover:
- single records
- multi-field types
- columnized alignment
- basic deriving
- deriving strategies
- existential quanitification
A few items block merger
- retaining comments
A few items can be deferred:
- normal types
- sum types
Both record construction and record layouting have very similar
constructions. These each had their own layouter with slightly different
variations. Variations here lead to subtley different bugs in layout for
nearly identicle syntactic forms.
The record update logic is more advanced and respects `IndentPolicyLeft`.
Instead of keeping these layouters distinct we can consolidate
construction logic into the update logic. This results in a smaller
volume of code and more uniform layouting of syntax for these simlilar
forms.
Record constructors with fields and wildcards are not included in this
consolidation. A TODO has been left to handle this consolidation later.
