Convert the remaining window.confirm() call sites to the in-app
MessageDialogHost, extended with a new confirm mode (Cancel + Confirm
buttons, optional danger styling) via showConfirmDialog().
Sites converted:
- New workspace (EditorPage)
- Load project / delete file (FileExplorer)
- Overwrite SPIFFS file (BoardOptionsModal)
- Delete VFS node (VirtualFileSystem)
All dialog strings are internationalized across the 9 supported locales
(en, es, pt-br, it, fr, zh-cn, de, ja, ru); the two previously
English-only modals now pull from i18n too.
useMessageDialogStore + <MessageDialogHost /> (mounted once in App.tsx)
give a themed in-app dialog callable from anywhere — React components
and plain .ts modules alike via showMessageDialog(msg, {kind}). Swaps
the native alert() calls in FileExplorer (import errors) and the
desktop menu (.vlx open errors, updater status) for it; the pro overlay
can reuse the same store.
(1) The explorer's per-board manifest entry is renamed velxio.json -> libraries.json
and clicking it now opens a READ-ONLY JSON view of that board's declared libraries
(board.libraries) in the editor, instead of the modal. New editor state
manifestViewBoardId: when set, CodeEditor renders a read-only Monaco showing
{libraries:[...]} live; opening/activating any real file clears it. No file is
added to the workspace, so nothing touches compile or save. Library actions are
done in the Library Manager modal (toolbar button).
(2) Drop the 'Uninstall' button for shared index/cache libraries — you can't
uninstall a copy everyone shares (content-addressed cache). Only your own custom
.zip uploads keep a 'Remove' (per-user store). Index libs: just Add to / In project.
Moved the velxio.json entry out of a single top-level row (ambiguous about
which board it applied to) into EACH board's file group, next to that board's
sketch. Each board now shows its own velxio.json with its own declared-library
count; clicking it switches to that board and opens the Library Manager on its
list. Makes the per-board manifest model unambiguous.
Library manifests are now PER-BOARD (each board carries its own velxio.json),
so two boards in one project can use different (even conflicting) libraries
without clashing — the multi-board extension of the no-clash guarantee.
- board.libraries on BoardInstance + serialisableBoard: rides in boards_json,
so it round-trips, dirty-checks, autosaves and restores natively. This also
removes the load-restore hacks (useLibraryManifestStore + applyProjectManifest
deleted): the manifest is plain board state.
- loadProjectState now restores per-board boardOptions/spiffsFiles/libraries
(it previously dropped them).
- EditorToolbar single + compile-all send the COMPILING board's libraries.
- Backend compile.py prefers the client's per-board request.libraries; the
project-level libraries_json (now the union of all boards) is the fallback.
- buildLoadPayload migrates pre-per-board projects: seed each board with the
project union so they keep compiling scoped.
- Library Manager 'In project' tab edits the ACTIVE board's velxio.json (shows
the board name) and the add field is now an autocomplete (installed libs +
index search) so users pick from a list instead of typing names.
Deletes useLibraryManifestStore.ts + applyProjectManifest.ts.
End users can now configure a project's declared libraries (the compile scope):
- Library Manager gains an 'In project' tab = the project's velxio.json:
declared libs as removable rows, quick add-by-name, and a raw velxio.json
editor. Installing a library auto-adds it to the project. Installed-tab rows
get an 'Add to project' toggle.
- FileExplorer shows a velxio.json entry (with declared count) that opens the
Library Manager via a window event the toolbar listens for.
- applyProjectManifest(): restore a saved project's manifest into the store on
load so the editor/toolbar/Library Manager/velxio.json reflect it.
- computeProjectStateHash() includes the manifest so declaring a library marks
the project dirty and autosaves.
Note: the OSS ProjectByIdPage also calls applyProjectManifest for parity, but
velxio.dev routes the pro-overlay ProjectByIdPage (wired separately).
Phase 2 of the run-system/UX work.
- BoardInstance gains an optional user ; boardDisplayName(board) resolver
(name || kind label) routes every INSTANCE-label surface: file-explorer
section header, compile console (EditorToolbar), canvas selector/tooltip/
context-menu, Serial Monitor tabs, Oscilloscope board picker, Board Options
subtitle. Board/component pickers keep the KIND label (they pick new boards).
- Inline rename on board AND chip section headers (double-click the name, or a
hover pencil button). Board -> updateBoard(id,{name}); chip -> chipName in
properties. Enter commits, Escape cancels (cancel-flag ref guards the
unmount-fires-onBlur footgun), empty clears to the kind / 'Custom Chip'.
- FileTabs shows an owner badge naming the board/chip whose files are shown
(resolved as a selector so it doesn't re-render on every sim pin toggle).
- CustomChipDialog no longer clobbers a user-given chipName: chip.json's name
only seeds the blank defaults (My Chip / Custom Chip); loading an example
relabels explicitly.
- Persistence: board name round-trips via projectPayload (+ dirty hash),
vlxFile, ProjectByIdPage load + loadProjectState; chipName rides components_json.
- Drive-by: fixed a pre-existing rules-of-hooks violation in BoardOptionsModal
(early return before a useCallback).
Reviewed by a 3-agent adversarial pass (completeness / persistence / correctness);
all major findings folded in.

Two fixes from live testing feedback:
1. Adding a programmable chip (Z80/8080) from the gallery created NO program
group — only the chip(s) from the example had one. Root cause: 'programmable'
was detected by a non-empty programFile, but a fresh chip's programFile is
empty until the user writes one. Now detection uses the canonical signal —
chip.json's programTargets — via isProgrammableChip(). When such a chip
lands with no program yet, the file explorer seeds an editable program.c
(DEFAULT_CHIP_PROGRAM_C, a working walking-LED skeleton) into its own group
and stamps programFile/programTarget onto the component so Compile/Run can
build it. Behaviour/driver and predefined chips (no programTargets) still
get no group — edited in the chip designer.
2. z80-led-chaser-c now runs board-less on a regulated power supply (no Arduino,
mirroring z80-larson-no-board) — the Arduino only ever supplied 5V and added
confusion. chaser.c stays the chip's editable program in its own section.
- romCompileService: isProgrammableChip(), DEFAULT_CHIP_PROGRAM_FILE/_C.
- FileExplorer: detect by programTargets; auto-seed program.c + persist
programFile/programTarget for fresh chips.
- examples-retro-intel: chaser-c -> board-less (psu + 8 resistors + 8 LEDs),
drop the now-unused Arduino sketch const; fix a stale sdcc --code-loc comment.
- Tests: board+chip case moved to z80-larson-scanner (still board-based);
isProgrammableChip unit tests.

A programmable custom-chip (a CPU emulator that runs a ROM/program, e.g. the
Z80 or 8080) now keeps its program (larson.s, chaser.c, ...) in a dedicated
editor file group — group-chip-<chipId> — rendered as its own collapsible
section in the file explorer, exactly like each board owns its sketch group.
Behaviour/driver chips and predefined chips carry no programFile and get no
group; they stay editable only in the chip designer.
Fixes two reported issues on the Z80 examples:
- /example/z80-larson-no-board: the board-less chip example now opens its
program (larson.s) as the active group, editable on the left — previously
the editor showed but no file appeared.
- /example/z80-led-chaser-c: the chip program (chaser.c) no longer shows as
a sibling tab inside the Arduino sketch group; it sits in its own chip
section instead. The board group shows only sketch.ino.
Details:
- useEditorStore: chipFileGroupId()/CHIP_GROUP_PREFIX helpers.
- loadExample: seedChipProgramGroups() routes each chip's programFile into its
own group (seeded from the example files), sweeps stale chip groups, keeps
the program OUT of the board group, and for a board-less chip example makes
the chip group active so the program is the editable file shown.
- EditorToolbar.prepareCustomChips: resolves the program from the chip's own
group (falls back to board files for older projects) before assembling ROM.
- FileExplorer: renders one collapsible section per programmable chip with an
IC icon; clicking switches the editor to the chip group. Lazy-creates a
group for chips dropped on the canvas.
- projectPayload + vlxFile: serialise chip groups alongside board groups and
include them in the dirty-check hash, so chip-program edits persist on
save / autosave / .vlx export and round-trip via replaceFileGroups on load.
- Regression tests for board-less + board+chip routing and stale-group sweep.

Adds stm32-f4-discovery, stm32-olimex-h405, stm32-netduino-plus2, stm32-netduino2, stm32-blackpill-f401 and stm32-bluepill-f103cb, mapped to existing qemu-lcgamboa machines (netduinoplus2, olimex-stm32-h405, netduino2, stm32vldiscovery). A generic inline board renderer (no SVG) draws the Discovery/Olimex/Netduino boards from a header pin layout; the Pill variants reuse the Blue/Black Pill SVGs. Per-board onboard-LED pin and polarity via STM32_LED. One blink+serial example per board.
tsc --noEmit clean; all new FQBN pnum variants present in STM32 core 2.12.0; worker smoke tests pass for the new machines.

STM32 emulation (open-core, runs via libqemu-arm in the backend worker):
- backend: stm32_lib_manager + stm32_worker (GPIO, USART, I2C/SPI device models
reusing the ESP32 slaves, live sensor updates), arduino_cli STM32 branch,
start_stm32 simulation route.
- frontend: Stm32Bridge + Stm32BluePill(/BlackPill) web components (Wokwi SVGs),
board kinds, Interconnect/boardPinMapping/boardProtocols wiring, example
projects (blink, serial, I2C BMP280/MPU6050/DS1307/SSD1306/weather, 7-seg,
RGB, button, switch, stepper, cross-board interconnect).
- Raspberry Pi 4/5 board elements + thumbnails.
Pro board gating (generic OSS->Pro seam; entitlement logic lives in the overlay):
- lib/proBoardGate.ts: isProBoardKind (STM32 + every QEMU Raspberry Pi),
installBoardGateImpl/boardGateDecision, triggerProUpgradePrompt.
- PRO badge on those boards in the component picker; gate at the picker add +
the run backstop (startBoard).
- backend/app/services/board_access.py: server-side enforcement seam for the
simulation WebSocket; STM32/Pi unavailable -> Pro-framed message.
- desktop: generic QemuDownloadPrompt + Stm32QemuPrompt (download-behind-license,
mirrors the ESP32 prompt).
- .gitignore: never ship libqemu-* binaries in the public image.

Velxio had two parallel import paths that confused users (reported on
Discord by AgUn / dmontero):
* Toolbar "Import a project from a .zip file" → Wokwi .zip only
* File-explorer "Open .vlx file" → Velxio .vlx only
If you exported a Velxio project as .vlx and tried to bring it back via
the toolbar Import button, you bounced off "wrong format" with no hint
that the .vlx loader was hiding behind the file-explorer save-bar.
Fix: introduce `utils/importProject.ts` as the single dispatcher. It
sniffs the extension and routes:
*.vlx → importVlxFile (writes directly to stores)
*.zip → importFromWokwiZip (returns a payload the caller applies,
so the toolbar can still trigger the
install-libraries modal afterwards)
Both UI entry points now go through the dispatcher with the same
`accept=".vlx,.zip,application/json,application/zip"` filter:
* Toolbar "Import project (.vlx Velxio or .zip Wokwi)"
* File-explorer "Open project (.vlx Velxio or .zip Wokwi)"
The toolbar tooltip is i18n-driven — updated EN + 8 other locales
(es, fr, de, it, pt-br, ja, ru, zh-cn) so every user sees the same
clarification.
Wokwi compatibility kept intact — the .zip path still resolves to
`importFromWokwiZip` and the same library-install modal pops if the
imported project lists libraries we don't have locally.
Phase 4 of the OSS / pro split. The OSS image has no auth and no
server-side persistence — without this commit, the user's workspace
was ephemeral (lost on tab refresh). `.vlx` is a single-file JSON
snapshot of the entire workspace (boards, file groups, components,
wires, active board id) that the user can save to disk and reload
later.
New: utils/vlxFile.ts
- buildVlxPayload() / buildVlxBlob() — pure snapshot of the current
editor + simulator stores.
- triggerDownloadVlx({ name? }) — anchor-click download with a safe
filename. Returns the filename actually used.
- parseVlxFile(File) — async reader + validator. Checks
format === "velxio-project", version <= 1, and the required
arrays/objects are present. Throws VlxParseError with a human-
readable message on any issue.
- importVlxFile(File) — convenience wrapper that parses AND calls
useSimulatorStore.loadProjectState() with the result.
Format intentionally mirrors the server's POST /api/projects body so
a Pro user can export-from-pro and import-into-OSS losslessly (and
vice-versa once Pro adds an Export button — out of scope here).
lib/proSaveAction.ts: the default (no-overlay) implementation now
calls triggerDownloadVlx() instead of console.info'ing about the
missing handler. The Pro overlay still wins via installSaveActionImpl()
— Save in Pro keeps opening SaveProjectModal. The Save button in OSS
now actually saves.
components/editor/FileExplorer.tsx: new "Open .vlx" button next to
New + Save. Opens a hidden file input; confirms with the user before
replacing the workspace (loadProjectState is destructive); surfaces
VlxParseError messages via window.alert.
Verified with both builds:
- OSS-only: triggerSaveAction → download .vlx; FileExplorer shows
3 buttons (New, Open, Save).
- OSS + overlay: Pro's installSaveActionImpl overrides — Save opens
SaveProjectModal as before. Open .vlx still works (independent
button, not part of the save flow).

FileExplorer (sidebar)
- Workspace header label and the new-workspace / save-project icon
buttons now read from t('editor.fileExplorer.*').
- Per-board section: collapse / expand toggle, status dot tooltip
(Running / Compiled / Idle), per-board "new file" button, and the
composite "<board name> — click to edit" hover title (the board
name itself stays untranslated — it's a product noun like
"Arduino Uno").
- File rows: hover title with optional "(unsaved)" suffix,
unsaved-dot tooltip, and the right-click context menu's Rename /
Delete commands.
- Empty-state placeholder when no boards are on the canvas.
- The window.confirm() shown before deleting a file now reads from
t() too, so non-English users see the prompt in their language.
FileTabs (open-tabs strip above the editor)
- Per-tab close button title and the unsaved-changes dot tooltip.
- Inline confirm dialog when closing a modified file: prompt copy,
"Close anyway" and "Cancel" buttons.
Hand-translated for all 9 locales. Hotkey hints (Ctrl+S, Strg+S)
localised per German convention; other locales keep "Ctrl+S" as the
universally-recognised label.
