From 230338e4359cae44740fb51350f6d6f92ee2f487 Mon Sep 17 00:00:00 2001 From: Thanan Traiongthawon <95660+nullcoder@users.noreply.github.com> Date: Fri, 6 Jun 2025 19:05:17 -0700 Subject: [PATCH 1/3] fix: refactor duplicate filename validation to parent component MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary - Move duplicate filename validation from FileEditor to MultiFileEditor - Update validation to show errors without blocking input (better UX) - Add onValidationChange callback for parent components - Update tests to reflect new validation behavior ## Changes - FileEditor now accepts an `error` prop for external validation errors - MultiFileEditor tracks duplicate filenames and passes errors down - Users can type freely while seeing validation errors in real-time - Form submission can be blocked at parent level based on validation state This provides a cleaner separation of concerns where MultiFileEditor owns the list of files and validates uniqueness, while FileEditor only handles local validation (empty names, invalid characters). 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- components/ui/file-editor.test.tsx | 62 ++++++++++++--------- components/ui/file-editor.tsx | 38 +++++++------ components/ui/multi-file-editor.tsx | 84 +++++++++++++++++++++-------- docs/TODO.md | 12 ++--- 4 files changed, 121 insertions(+), 75 deletions(-) diff --git a/components/ui/file-editor.test.tsx b/components/ui/file-editor.test.tsx index e3a2ff0..1518f8e 100644 --- a/components/ui/file-editor.test.tsx +++ b/components/ui/file-editor.test.tsx @@ -25,7 +25,6 @@ describe("FileEditor", () => { onChange: vi.fn(), onDelete: vi.fn(), showDelete: true, - existingFilenames: ["test.js", "other.txt"], };
