- FileTree menerima prop language ('c' | 'python', default 'c')
- hanya merender file dengan ekstensi yang cocok (.c atau .py)
- tombol + buat file dengan ekstensi bahasa aktif
- header menampilkan nama bahasa (C/Python), bukan generik 'File'
- runActiveFile() memanggil consumeStdin() (antrean + draft, digabung, dikosongkan)
- pesan info jika stdin kosong: program yang membaca input akan mendapat EOF
- hapus pembacaan consoleInput langsung yang menyebabkan baris hilang
- playground route: velxio/flowchart/circuit/code tabs with auto-save
- FileTree + ConsolePanel for C/Python code tab
- compileCode() forwards stdin through routes/compile.py to compiler_worker
- compiler_worker run_c_code/run_python_code accept stdin, pass via subprocess.run(input=)
- known issue: Console UI does not queue stdin properly → fix in next cycle
Update velxio submodule pointer to the new integration branch that contains:
- EmbedBridge.ts PostMessage bridge for iframe integration
- DeployProgress UI for compile/transfer/flash status
- BASE_URL customization for /velxio/ path
- Backend auth, project, and database endpoints for Elemes LMS
- SerialMonitor BLE/Hardware toggle support
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
Consolidates all dev work including the orphaned-read race fix:
- Single read-pump feeds a FIFO ByteStreamBuffer; readExact/drain/
serial monitor consume from buffer (no orphaned reader.read()).
- DTR timing 50ms+100ms, port reuse, pre-sync drain.
- Vitest + ByteStreamBuffer unit tests (7 pass).
- APP_VERSION 18 for SW cache-bust.
Verified on CH340 (1a86:7523): INSYNC 0x14 + STK_OK 0x10
received cleanly, deploy succeeds.
WARN-1: pumpRunning now reset to false when the pump loop exits via
{done} or error, so future startPump() isn't a silent no-op.
WARN-3: readExact clears rxBuffer on timeout to avoid stale bytes
leaking into the next non-retried STK500 command.
readExact and drainStray now consume the FIFO buffer fed by the pump
instead of calling reader.read() directly. No orphaned reader.read()
promise can swallow optiboot INSYNC/OK replies anymore. This is the
core fix for "get_sync failed after N attempts".
Single pump loop becomes the only reader.read() caller, feeding
rxBuffer. Serial monitor + readExact/drain will consume from the
buffer (next tasks). Build passes.
Test runner setup (vitest) plus deadline-based FIFO buffer that
becomes the single sink for serial bytes. readExact keeps
partial bytes buffered on timeout — the exact case that dropped
optiboot INSYNC/OK replies under the orphaned-reader race.
7 unit tests pass.
- 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
- Add device_name module: NVS-persisted custom name with MAC-suffix
fallback (Velxio-XXXX) so every device is uniquely identifiable
out-of-the-box in BLE pairing dialog
- Add wifi_ap module: first-boot SoftAP (Velxio-Setup-XXXX / velxio123)
with embedded HTTP config portal at 192.168.4.1 for renaming
- main.c: enter AP setup mode when no custom name is set
- ble_service.c: use dynamic device name from device_name_get(),
with adv-packet length guard
- led_button.c: BOOT button long-press (5s) factory reset (erase NVS)
- sdkconfig.defaults: enable WiFi stack + set NimBLE default name
Frontend deviceName display already committed in 01f68d3.
