Reviewer's Guide

Refactored reflow_table by extracting its core responsibilities (indent/trimming, separator detection, parsing/validation, formatting) into dedicated helper functions, introduced a ParsedTable struct to encapsulate intermediate state, and streamlined the main function into a linear helper pipeline.

🔇 Additional comments (9)
docs/release-process.md (1)

30-30: LGTM: Correct grammatical fix applied.

The article correction from "A" to "An" before "SHA-256 checksum" is proper English usage since "SHA" begins with a vowel sound.

docs/rust-testing-with-rstest-fixtures.md (1)

1203-1204: LGTM: Proper typographical ellipsis applied.

The replacement of ASCII triple-dot sequences with Unicode ellipsis characters in the attribute examples improves typographical consistency throughout the documentation.

src/reflow.rs (1)

73-84: LGTM: Efficient borrowing approach implemented.

The change from taking ownership (Vec<Vec<String>>) to borrowing (&[Vec<String>]) improves efficiency by avoiding unnecessary data moves. The corresponding updates to use iter() instead of into_iter() are correct and necessary for the borrowed data.

src/table.rs (6)

94-108: LGTM: Well-documented struct encapsulates parsed data.

The ParsedTable struct effectively encapsulates the intermediate results from table parsing with clear documentation. The struct fields are well-named and the rustdoc comments provide sufficient detail about each field's purpose.


110-122: LGTM: Clear extraction of indentation and trimming logic.

The extract_indent_and_trim function properly separates the concerns of extracting leading whitespace and filtering out escaped pipe marker lines. The documentation clearly explains the purpose of filtering lines beginning with \-.


124-128: LGTM: Focused separator line extraction.

The extract_separator_line function has a single, clear responsibility of finding and removing the first separator line. The implementation is concise and correct.


130-149: LGTM: Comprehensive parsing and validation logic.

The parse_and_validate function effectively combines parsing, validation, and data preparation. The early return on mismatched rows provides clear error handling, and the construction of the ParsedTable struct organises the results well.


151-162: LGTM: Clean formatting pipeline.

The calculate_and_format function properly chains the width calculation, row formatting, and separator insertion steps. The parameter signature correctly borrows the input data for efficiency.


164-184: LGTM: Excellent refactoring of main function.

The reflow_table function now follows a clear, readable pipeline: extract → parse → validate → format. The early returns on empty input and validation failure provide proper error handling whilst maintaining the original function's behaviour.

<issue_to_address>
calculate_and_format takes ownership of output_rows, which may be unnecessary.

Consider changing the parameter to borrow output_rows instead of taking ownership to avoid unnecessary allocations or moves.

Suggested implementation:

```rust
+fn calculate_and_format(
+    cleaned: &[Vec<String>],
+    output_rows: &[Vec<String>],

```

You will also need to update all call sites of `calculate_and_format` in this file (and possibly others) to pass `&output_rows` instead of `output_rows`. If the function is public or used in other modules, those usages must be updated as well.

114-118: Function implementation looks correct.

The extract_separator_line function correctly removes and returns the first separator line found. The implementation is clean and follows the single responsibility principle.


141-152: Function implementation is correct and well-structured.

The calculate_and_format function properly chains the width calculation, row formatting, and separator insertion. The implementation follows the single responsibility principle and maintains good separation of concerns.


154-174: Refactored function maintains correctness whilst improving readability.

The refactored reflow_table function successfully chains the helper functions and maintains the original behaviour. The early return pattern with let Some(parsed) = parse_and_validate(...) is idiomatic Rust and improves readability.


120-139: Improve error handling and consider early returns.

The function correctly implements validation logic but could benefit from clearer error handling and more explicit early returns.

 /// Parses table rows and validates column consistency.
+///
+/// Returns `None` if rows have mismatched column counts (indicating invalid table structure).
 fn parse_and_validate(trimmed: &[String], sep_line: Option<&String>) -> Option<ParsedTable> {
     let (rows, split_within_line) = crate::reflow::parse_rows(trimmed);
     let max_cols = rows.iter().map(Vec::len).max().unwrap_or(0);
     let (sep_cells, sep_row_idx) = crate::reflow::detect_separator(sep_line, &rows, max_cols);
     let cleaned = crate::reflow::clean_rows(rows);
+    
     if rows_mismatched(&cleaned, split_within_line) {
         return None;
     }
+    
     let mut output_rows = cleaned.clone();
     if let Some(idx) = sep_index_within(sep_row_idx, output_rows.len()) {
         output_rows.remove(idx);
     }
+    
     Some(ParsedTable {
         cleaned,
         output_rows,
         sep_cells,
         max_cols,
     })
 }

Likely an incorrect or invalid review comment.


126-128: Ignore outdated review comment: validation stage unchanged

Note the rows_mismatched check remains at the same point in parse_and_validate:

  • origin/main (src/table.rs:123):
    if rows_mismatched(&cleaned, split_within_line) { … }
  • PR branch (src/table.rs:126):
    if rows_mismatched(&cleaned, split_within_line) { return None; }

No change to validation timing or behaviour.

Likely an incorrect or invalid review comment.

151-162: Address ownership issue in function parameters.

The function takes ownership of output_rows and sep_cells parameters unnecessarily. Change to borrowing to avoid unnecessary moves and align with the previous review feedback.

Apply this diff to use borrowing:

 fn calculate_and_format(
     cleaned: &[Vec<String>],
-    output_rows: &[Vec<String>],
-    sep_cells: Option<Vec<String>>,
+    output_rows: &[Vec<String>],
+    sep_cells: Option<&Vec<String>>,
     max_cols: usize,
     indent: &str,
 ) -> Vec<String> {
     let widths = crate::reflow::calculate_widths(cleaned, max_cols);
     let out = crate::reflow::format_rows(output_rows, &widths, indent);
-    crate::reflow::insert_separator(out, sep_cells, &widths, indent)
+    crate::reflow::insert_separator(out, sep_cells.cloned(), &widths, indent)
 }

Update the call site accordingly:

 calculate_and_format(
     &parsed.cleaned,
     &parsed.output_rows,
-    parsed.sep_cells,
+    parsed.sep_cells.as_ref(),
     parsed.max_cols,
     &indent,
