v1.1.2

KronEditor v1.1.2
🤖 PLC Agent
New: the agent asks instead of guessing. A clarifying question is now a real tool call (ask_user), not prose. It renders as a VSCode-style quick-pick above the input bar (buttons when the model supplies options, a text box when it doesn't, always with a free-text escape), pauses the run until you answer, and asks multiple questions one at a time with an n / total counter. Previously the model dumped a numbered list of questions into a chat bubble and the loop just ended — nothing was actually waiting for you.

Run state you can see and stop. The Stop control moved into the input bar (the send ➤ becomes a red ■; Esc also stops) — it used to live at the bottom of the scrolling conversation, so in a long chat it was below the fold and the agent looked unstoppable. Added a phase label + ticking elapsed timer as proof of life, and stopping is now generation-based, so a stopped run can never resume alongside a new one. Approving a proposal correctly re-arms the running indicator.

Model picker now reads a live catalogue. New POST /api/host/ai/models endpoint proxies each provider's list endpoint; the built-in lists are only an offline fallback. The Model field is a proper (the old free-text combo used its own input as the filter, so a user on claude-opus-4-8 could see only that entry and couldn't reach any other model). Non-chat models (embeddings, tts, image, moderation) are filtered out of OpenAI-shaped lists, and the Connect tab waits for the first fetch instead of showing a stale list. New provider: DeepSeek (deepseek-chat / deepseek-reasoner). Providers are now grouped in the picker by how you authenticate (sign-in / API key / local / custom) rather than by vendor. Provider connection fixes: A named provider always reaches its own host — baseUrl is honored only by custom. A leftover Ollama/custom base URL used to silently redirect every provider (picking Gemini + a valid key POSTed to localhost:11434 and failed with connection refused) and sent the API key as a Bearer token to whatever host that base named. Switching provider in Settings no longer carries apiKey/baseUrl across; credentials are stashed per provider. Gemini: model listing uses the native /v1beta/models route (the OpenAI-compat one 404s unauthenticated), fallback list uses the -latest aliases that can't go stale, and Gemini 3's per-tool-call thought_signature is round-tripped verbatim — without it multi-turn tool use died on turn 2 with a 400. Provider errors are condensed into one actionable sentence (friendlyProviderError); it tells a zero-quota plan apart from an ordinary rate limit, and catches Google's 400 "Please pass a valid API key" which isn't a 401. Ladder/ST authoring correctness: Agent-authored ladder blocks now land on the power rail. They were all emitted at y=0, parking every contact and coil ~75 px above the rail with diagonal wires. On a mixed POU, set_st_code and set_ladder each own only their own language's rungs. Before this, whichever ran last deleted the other's work — authoring a rung then writing ST wiped the ladder. set_ladder now validates contact/coil targets and fails loudly: non-IEC names, non-BOOL targets, unknown subTypes and comparison-ish names (EQ, GT, >=) are rejected with a routing hint instead of being silently normalized into nonsense like counter AND 10. add_variable accepts standard FB types (TON, CTU, MC_Power, …) — the prompt told the model to do exactly this and it was rejected for every standard FB. It also refuses to create a local that shadows a global. read_pou returns the POU's referenced globals, so the model stops re-declaring them as locals. list_blocks documents each FB's trigger pin and power-output pin. An explicit "write it in ladder" now outranks the content-based language heuristic — a "count to 10" request no longer silently comes back as ST. Better weak-model handling: bare JSON arg objects are routed by shape, and POU-target errors name the POUs that actually exist. 🔧 Build & toolchain Build & Send was broken for every armv7 BeagleBone — fixed. The bundled GCC install dir is now located by glob and passed as -B (paths.go LLVMGCCInstallDir). The sysroots name it with a "none" vendor (arm-none-linux-gnueabihf) that clang's candidate list doesn't match for arm, so every -static target build died with cannot open crtbeginT.o / unable to find library -lgcc; aarch64 worked only by luck. Version dirs are compared numerically (9.3.0 vs 10.2.1), covered by a new paths_gcc_test.go. 🔌 HAL — no more fake success Stub _Call bodies that returned DONE = EN / VALUE = 0, ERR_ID = 0 were indistinguishable from a working read, so projects could silently run on invented data. Everything is now either real or reports ERR_ID. BeagleBone HAL is now implemented (was almost entirely TODO): GPIO on both headers, PWM (sysfs), I2C, SPI single-byte + burst, ADC (AM335x IIO, 12-bit / 1.8 V), CAN (SocketCAN dcan0/dcan1), UART/USB device paths corrected to /dev/ttyS*, DI/DO. The BeagleBone P8 pin map was all -1 placeholders — every P8 GPIO silently failed. It now carries the real AM335x line ids from the BBB SRM. PWM was dead on all 12 generic-Linux SBCs. Channels are now flattened across pwmchips (sorted by index) instead of requiring one chip to expose them all — Rockchip/Amlogic boards publish one chip per PWM cell. KRON_PWM_MAX raised to 8, with HAL_Init explicitly setting fds to -1 (a static-zero fd would have made cleanup close stdin). RPi HAL: real single-byte SPI, generic ADC via IIO (honors the driver's _scale), SocketCAN. Jetson: ADC honestly reports ERR_ID=1 (dev kits expose no user ADC), SocketCAN added. 🧩 Board list Raspberry Pi Pico / Pico W removed. The whole product (KronServer agent, /dev/shm IPC, hot-swap dlopen) assumes a Linux userspace — a Cortex-M board could only ever simulate, deploy was always rejected. kronhal_pico.h and the Pico pin renderer are gone. Old projects still targeting a Pico now get a clear "reselect a Linux board in Board Config" error on Build/Deploy/Hot-swap instead of silently building a wrong-arch binary. Peripheral counts corrected against real silicon (a channel count mints blocks in the toolbox, so an optimistic number is a promise the hardware must keep): Jetson Nano's phantom CAN removed (Tegra X1 has no CAN controller), Jetson TX2 → 2 CAN, RK3588 boards (Orange Pi 5 / 5 Plus, ROCK 5B) gained the CAN they really do have via can0-m0/can1-m0 overlays, ODROID-C4 → 6 PWM + 2 header ADC inputs (⚠️ 1.8 V ceiling, not 3.3 V). ✏️ Editor Ctrl+C no longer hijacks a text selection. Selecting text in a plain div — an agent chat bubble, an error message, a diff line — leaves focus on , so every focus guard passed and Ctrl+C replaced the highlighted text with a copied POU. All global clipboard handlers now bail on hasTextSelection(), and the agent panel claims its own editor scope. ⚠️ Upgrade notes If a saved project targets rpi_pico/rpi_pico_w, open Board Config and pick a Linux board. BeagleBone armv7 users: Build & Send works again — no project change needed. No KronServer changes in this release; an existing target agent does not need redeploying.

hot reload added

KronEditor 1.1.1
First tagged release since 1.0.0. Focus: live editing while running (online change), a real AI agent workflow, and shippable installers.

✨ Highlights
Online change (hot reload). Edit Ladder/ST while the simulation runs and apply it live with a Hot Reload toolbar button — timers, counters and latches survive. Layout-changing edits (adding an FB, a variable, a task) can't hot-reload; they're detected up front and offered as a one-click rebuild + restart that carries over existing variable values (a counter at 35 resumes at 35, not 0). Guarded by two layers: a JS layout pre-check and the C-level plc_state_layout_hash safety net.

Pulse vs Force live writes. Manually writing a live value now offers Pulse (inject for one scan, logic resumes) or Force (hold it pinned). Pulse is the fix for "I set the counter to 0 and it froze" — force pins, pulse seeds.

PLC Agent upgrades.

Manual / Auto mode — review each change as a diff, or let the agent apply directly.
Ask agent from any error: the error popup (now a full, copyable modal) sends the message to the agent for an explanation/fix.
Animated "thinking/working" indicator.
Ollama: the model pill is green only when the daemon is actually running (with a Stop button and auto-recovery), instead of falsely green.
🪜 Ladder editor
Straight wires — the power line is fixed and blocks magnet-snap onto it (measured from the real handle), ending the "kayma"/stepped-wire drift.
Undeclared variables are flagged — a pin wired to an unknown name (e.g. var5) shows a red border + tooltip explaining it, instead of silently failing at build.
Block "How it works" notes — double-click a block to see behaviour notes (subtype-aware), localized in EN/TR/RU.
ANY_NUM pins keep autocomplete after a literal is typed; editable pins work correctly during a running sim.
TIME auto-format — type 500ms or 500, get T#500ms (bare number = milliseconds), in both PT pins and variable initial values.
Ctrl+Shift+Z (redo) now layout-independent.
🔢 Types & validation
64-bit types LINT / ULINT / LREAL / LWORD selectable; host-agent now encodes/decodes BYTE/WORD/DWORD/LWORD too.
Variable names validated as IEC identifiers (no spaces/punctuation).
Same-named locals in different programs no longer wrongly rejected.
📦 Packaging & release
Linux AppImage — build fixed (missing AppRun/desktop assets added); one self-contained file with toolchains.
Windows — portable ZIP plus a real installer: KronEditor-1.1.1-Setup.exe (530 MB, bundles the app + resources + LLVM toolchains → one install, Build & Send works; local simulation is Linux-only).
packaging/requirements.md documents build prerequisites.
Compile/build now shows a spinner + progress cursor.
⚙️ Under the hood
Header/include resolution moved to the shared krontek-include tree.
Loader-host cache keyed by content hash (a stale loader no longer breaks sim cold-start).
Version single-sourced from package.json everywhere.
⚠️ Known limitations
Field hot-swap on real hardware is unverified — online change is proven on the local sim (compile/unit/HTTP verified for the field path), but a physical-device swap + operator safe-state review are still pending. Build & Send (full redeploy + restart) is the reliable target path.
Local simulation is Linux-only (reads /proc//dev/shm); on Windows the editor + Build & Send work, RUN does not.
EtherCAT/motion aren't hot-swap-trampolined — those need a full redeploy.
