- Export siswa terpilih/seluruh + progress ke CSV round-trip (token tidak
pernah diekspor; teacher tidak ikut; urutan deterministik)
- Import preview all-or-nothing: siswa existing di-restore (nama+progress,
token lama dipertahankan), siswa baru dibuat dari student_id kosong +
token; conflict tidak menyebut raw token/digest
- Bulk delete multi-seleksi dengan validasi ketat (teacher terlindungi,
zero-delete bila ada ID bermasalah)
- fix(import): deteksi delimiter berbasis schema — menerima titik koma
(;) maupun koma (,), ekspor tetap ';' + BOM; header tab/campuran ditolak
dengan pesan jelas (regresi: file Excel/Sheets kini bisa diimpor)
- refactor: progress_status.py — kontrak status legacy tunggal dipakai
storage PG, export, dan import; report siswa hanya role student
- UI /progress: dialog import/export + bulk delete, selection store,
respon import tanpa raw token; APP_VERSION 22 -> 26
- ops: ORIGIN env var di podman-compose.yml
- docs: README section 9 (workflow round-trip + delimiter) dan
docs/11-database-migration (kelola siswa via round-trip CSV)
- test: parser round-trip (45), repositories, route management (24,
PostgreSQL), frontend 91, fixtures CSV valid/invalid
Restructure quiz flow into QuizSession primitive + atomic quiz state in
LessonManager, and extract QuizQuestionView for split-view display.
Tab-safety fix: add lesson-tabs.ts with pickDefaultTab(), getAvailableTabs()
mirroring the exact {#if} conditions in +page.svelte, and ensureActiveTab()
safety-net that falls back to pickDefaultTab() when the desired tab is not
rendered. A reactive $effect in lesson/[slug]/+page.svelte validates
activeTab against lesson data on every change, preventing the "tab quiz
kosong" (empty workspace) regression for quiz-only lessons and phantom-tab
state after data changes.
Files:
- lib/services/lesson-tabs.ts (+test): pure helpers, 18 tests pass
- lesson/[slug]/+page.svelte: ensureActiveTab reactive guard + QuizQuestionView
- lesson/[slug]/lesson.svelte.ts: atomic startQuiz, getExitStatus, idempotent
submit on navigate/exit
- lib/services/quiz-session.ts (+test), lib/types/quiz.ts, QuizTab.svelte
(mgr-driven), QuizQuestionView.svelte, lesson.css
- services/lesson_service.py, services/tests/test_lesson_service_quiz.py
(test_lesson_service_quiz.py), requirements.txt (+pytest)
- docs/07-quiz-authoring.md
- version.ts APP_VERSION 21 -> 22 (forces SW update for the fix)
- examples/content/dasar/quiz_test.md synced to live content root
- Generalize _read_md_cached() for generic file caching
- Add find_sub_home_for_lesson() and get_sub_home_data() helpers
- Add /api/bab/<folder> endpoint
- Detect sub-home in api_lesson for nav context
- Skip sub-home.md in find_lesson_file() and _parse_lesson_links()
- Add title to bab frontend page data
- Update generate_tokens.py & content_parser.py to skip sub-home.md
- Update lesson_service.py to parse markdown link format [title](path)
- Convert all lesson files to use markdown link format for prerequisites
- Backend now extracts slug directly from link path
- Supports both plain text and markdown link formats
+page.svelte dan perbaiki backend parser
Pembaruan ini
mencakup:
- Refactoring skala besar pada halaman lesson SvelteKit untuk efisiensi kode.
- Ekstraksi evaluasi Code, Circuit, dan Velxio ke dalam direktori lib/services/.
- Memisahkan manajemen iframe (Zustand & PostMessage) ke velxio-manager.ts.
- Memisahkan Tab Panel HTML menjadi komponen spesifik (CodeTab, CircuitTab, VelxioTab).
- Ekstraksi blok <style> menjadi stylesheet terpisah (lesson.css).
- Perbaikan warning A11y & penghapusan class usang pada Navbar.svelte.
- Memperbaiki regex parser 'Available_Lessons' pada lesson_service.py di backend.
- Menambahkan mekanisme auto-append ekstensi '.md' untuk mengatasi bug Home kosong dan tombol 'Next Lesson' yang hilang akibat format URL baru di home.md.
3 - Integration of KaTeX in frontend (SvelteKit) with a custom
renderMath` action.
- Added `python-markdown-math` extension in backend (Flask). to handle math blocks.
- Configured Vite to handle KaTeX during SSR and browser rendering.
- Added a LaTeX test lesson and updated home navigation.
- Supported both inline ($) and block ($$) math rendering,
including multi-line support.
Implements multiple layers of security to address high-risk session
and authentication vulnerabilities identified in the security review:
- Allow code compilation (C, Python, Arduino) for anonymous users.
- Enforce a 1-request-per-2-minutes rate limit for anonymous IPs.
- Implement a global anonymous compilation queue with 20 concurrent slots.
- Proxy Velxio (Arduino) compilation through Flask to prevent API hijacking.
- Exempt authenticated users (tokens/cookies) from all rate limits.
- Fix networking and DNS resolution in podman-compose.
- Fix Svelte a11y warnings and trailing slash routing issues.
- Cookie Security: Added dynamic 'secure' flag support via COOKIE_SECURE
env variable for HTTPS/Tailscale Funnel compatibility.
- Rate Limiting: Integrated Flask-Limiter on /login (50 req/min) to
prevent API abuse while accommodating shared school networks (NAT).
- Tarpitting: Added 1.5s artificial delay on failed logins to neutralize
automated brute-force tools without blocking legitimate users.
- Session Invalidation: Implemented an in-memory token blacklist on
logout to ensure session tokens cannot be reused.
- Documentation: Updated technical docs and proposal status to reflect
the current security architecture.
Ref: @elemes/proposal.md (Poin 6.1, 6.2, 6.3)
- Added CircuitJSApi interface for simulator API interaction.
- Updated lesson page to support circuit simulation alongside code execution.
- Implemented separate output states for code and circuit evaluations.
- Enhanced lesson content rendering to include circuit embeds using markdown.
- Refactored backend to process circuit embed syntax and convert to HTML.
- Updated podman-compose configuration to include new environment variable for cursor offset.
- Created a proposal document outlining the feasibility and implementation plan for CircuitJS1 integration.
