This is a review of the pgindent multiline comments patch: https://www.postgresql.org/message-id/attachment/189778/v6-0001-pgindent-improve-formatting-of-multiline-comments.patch
Contents & Purpose ================== This patch adds a `postprocess_multiline_comment()` function to pgindent that reformats multiline comments to put `/*` on its own line: Before: /* This is line 1 * This is line 2 */ After: /* * This is line 1 * This is line 2 */ The patch correctly excludes Doxygen (`/**`), compat flag (`/*-`), and separator patterns (`/* ===`, `/* ---`). Initial Run =========== The patch applies cleanly to HEAD. I tested with various comment styles and all cases passed: - Basic multiline: reformatted correctly - Doxygen/compat: left unchanged (correct) - Separator lines: preserved (correct) - Single-line comments: left unchanged (correct) - Already-correct format: left unchanged (correct) The validation logic at line 303 correctly requires `/*` on its own line and ` */` on its own line before processing. Comments that don't match this pattern are returned unchanged. Performance =========== Tested on a 74KB C file: 0.038 seconds. Negligible impact; the regex only runs on comments. Nitpicking & Conclusion ======================= Minor: The regex notation in the report (line 85) shows `!` as part of the pattern when it's actually the delimiter. The code itself is correct. The validation description could be clearer that it returns early (skips processing) when conditions aren't met, rather than "requires" them. Otherwise this is a clean, minimal patch (36 lines) that fits well with existing pgindent patterns. Single file change, no build system modifications, developer tool only.
