For example: +``` +let f = fun x -> + let + body +in f(1) +``` +Here the `in` at column 0 gets matched to the INNER incomplete `let`, not the outer one. To test the relative indent heuristic in nested contexts, use forms that can't steal delimiters (like `fun` which uses `->`). + +### Future Refinements + +**Blank-line refinement (TODO):** +Currently blank-line = two consecutive linebreaks. Should generalize to: linebreak, followed by any combination of whitespace/grout (no tiles), followed by linebreak. This handles cases where grout insertion leaves a "blank" line with concave grout on it. + +### Known Indentation Bugs + +**Operator continuation doesn't auto-indent (TODO):** +When typing `let x = 1` then Enter then `+ 2`, the `+ 2` should ideally get auto-indented (it's a continuation of the expression). Currently, the indentation logic doesn't handle this case - the user must manually indent. This is acceptable for now but should be fixed in `Indentation.re`'s `is_incrementor` or related logic. + +**Case expression auto-indent (FIXED):** +Previously, pressing Enter in a complete case expression gave unwanted 2-space indentation. This was fixed by: +- Adding `effective_prev_pieces` and `effective_next_pieces` to skip over grout/linebreaks +- Adding `is_complete_case_rule_with_body` to detect complete rules with content +- Adding indentation rules that reset to base after complete case rules + +Tests in `Test_Editing.re` under `case_indent_tests` and `nested_case_tests` verify this behavior. + +### Case Rule Completion Skip (Load-Bearing) + +`Indentation.re`'s `shallow_complete_segment` skips completing case rules (tiles with label `["|", "=>"]`). This is **load-bearing** - removing it causes 3 tests to fail (incomplete `|` swallows siblings as body). + +Rationale: case rules are sibling-oriented (they don't nest into each other), so swallowing subsequent content as children is wrong. + +### Editor Improvements + +**Trailing whitespace cleanup:** +Lines may accumulate trailing whitespace (spaces before linebreaks).
