Intellisense in IDE 20 beta? [solved]

anon33446669 · April 13, 2021, 3:44pm

Hello,
I'm pretty sure arduino IDE is supposed to have intellisense like in vsc but I can't get it to work. it worked at one point but now it won't work anymore. does anyone know how to fix this?

File -> Preferences -> Editor Quick Suggestions. Put a tick in the box.

That tick box needs fixing.

When File → Preferences is opened the tick is empty. Tick it and the option is turned on. When File → Preferences is opened again it is once again blank. Tick it again and the option is turned off.

It currently acts as a toggle with the tick box only confirming you are actually ticking it, not showing the current status of the option.

EDIT: I also find if I use a board like the ATtiny3217 (using megaTinyCore), the option is not functioning at all (neither the hover popups). It does work for all the other boards I tried.

Willem.

I have noticed the same bug with that preference. I haven't found the time to submit a bug report for it yet. You are welcome to do so here:
https://github.com/arduino/arduino-ide/issues

I actually prefer to not have these pop-ups automatically because I find them distracting. You can trigger them on-demand with the Ctrl/⌘ + Space keyboard shortcut.

This is a known bug:

topic: language server criticality: medium

### Describe the problem The features that rely on the language server (autoc…omplete, editor hover, "Go To Definition", "Go To Symbol", "Peek Definition") don't work when a board from the Arduino "megaAVR" architecture (megaAVR 0-series, ~~tinyAVR 0-series and 1-series~~) (e.g., Nano Every, Uno WiFi Rev2) is selected. ### To reproduce 1. Use the Arduino IDE "**Boards Manager**" to install the "**Arduino megaAVR Boards**" platform, if not already installed. 1. Select **File > New** from the Arduino IDE menus. 1. Select **Tools > Board > Arduino megaAVR Boards > Nano Every** from the Arduino IDE menus. 1. Hover the mouse pointer over `setup` in the sketch code code 🐛 No "hover" popup appears. 1. Right click on `setup()` 1. Select "**Go To Definition**" from the context menu. 🐛 A "**No definition found for 'setup'**" tooltip appears. 1. Right click on `setup()` 1. Select "**Go To Symbol**" from the context menu. 🐛 The command palette shows "**No editor symbols**" 1. Right click on `setup()` 1. Select "**Peek > Peek Definition**" from the context menu. 🐛 A "**No definition found for 'setup'**" tooltip appears. 1. Type the following code inside the `setup` function: ```cpp pinMo ``` 1. Press <kbd>**Ctrl**</kbd>+<kbd>**Space**</kbd> 🐛 The "suggest" interface shows "**No suggestions.**" ### Expected behavior Language server features to work on megaAVR boards just like on boards of other architectures. ### Arduino IDE version #### Original report 2.0.0-beta.2-snapshot.f9730ab #### Last verified with 2.0.0-rc9.3 ### Operating system Windows, Linux ### Operating system version Windows 10, Ubuntu 20.04 ### Additional context From `inols-clangd-err.log`: ``` V[12:54:19.163] Ignored diagnostic. unknown target CPU 'atmega4809' V[12:54:19.163] Ignored diagnostic. valid target CPU values are: avr1, avr2, avr25, avr3, avr31, avr35, avr4, avr5, avr51, avr6, avrxmega1, avrxmega2, avrxmega3, avrxmega4, avrxmega5, avrxmega6, avrxmega7, avrtiny, at90s1200, attiny11, attiny12, attiny15, attiny28, at90s2313, at90s2323, at90s2333, at90s2343, attiny22, attiny26, at86rf401, at90s4414, at90s4433, at90s4434, at90s8515, at90c8534, at90s8535, ata5272, attiny13, attiny13a, attiny2313, attiny2313a, attiny24, attiny24a, attiny4313, attiny44, attiny44a, attiny84, attiny84a, attiny25, attiny45, attiny85, attiny261, attiny261a, attiny441, attiny461, attiny461a, attiny841, attiny861, attiny861a, attiny87, attiny43u, attiny48, attiny88, attiny828, at43usb355, at76c711, atmega103, at43usb320, attiny167, at90usb82, at90usb162, ata5505, atmega8u2, atmega16u2, atmega32u2, attiny1634, atmega8, ata6289, atmega8a, ata6285, ata6286, atmega48, atmega48a, atmega48pa, atmega48pb, atmega48p, atmega88, atmega88a, atmega88p, atmega88pa, atmega88pb, atmega8515, atmega8535, atmega8hva, at90pwm1, at90pwm2, at90pwm2b, at90pwm3, at90pwm3b, at90pwm81, ata5790, ata5795, atmega16, atmega16a, atmega161, atmega162, atmega163, atmega164a, atmega164p, atmega164pa, atmega165, atmega165a, atmega165p, atmega165pa, atmega168, atmega168a, atmega168p, atmega168pa, atmega168pb, atmega169, atmega169a, atmega169p, atmega169pa, atmega32, atmega32a, atmega323, atmega324a, atmega324p, atmega324pa, atmega324pb, atmega325, atmega325a, atmega325p, atmega325pa, atmega3250, atmega3250a, atmega3250p, atmega3250pa, atmega328, atmega328p, atmega328pb, atmega329, atmega329a, atmega329p, atmega329pa, atmega3290, atmega3290a, atmega3290p, atmega3290pa, atmega406, atmega64, atmega64a, atmega640, atmega644, atmega644a, atmega644p, atmega644pa, atmega645, atmega645a, atmega645p, atmega649, atmega649a, atmega649p, atmega6450, atmega6450a, atmega6450p, atmega6490, atmega6490a, atmega6490p, atmega64rfr2, atmega644rfr2, atmega16hva, atmega16hva2, atmega16hvb, atmega16hvbrevb, atmega32hvb, atmega32hvbrevb, atmega64hve, at90can32, at90can64, at90pwm161, at90pwm216, at90pwm316, atmega32c1, atmega64c1, atmega16m1, atmega32m1, atmega64m1, atmega16u4, atmega32u4, atmega32u6, at90usb646, at90usb647, at90scr100, at94k, m3000, atmega128, atmega128a, atmega1280, atmega1281, atmega1284, atmega1284p, atmega128rfa1, atmega128rfr2, atmega1284rfr2, at90can128, at90usb1286, at90usb1287, atmega2560, atmega2561, atmega256rfr2, atmega2564rfr2, atxmega16a4, atxmega16a4u, atxmega16c4, atxmega16d4, atxmega32a4, atxmega32a4u, atxmega32c4, atxmega32d4, atxmega32e5, atxmega16e5, atxmega8e5, atxmega32x1, atxmega64a3, atxmega64a3u, atxmega64a4u, atxmega64b1, atxmega64b3, atxmega64c3, atxmega64d3, atxmega64d4, atxmega64a1, atxmega64a1u, atxmega128a3, atxmega128a3u, atxmega128b1, atxmega128b3, atxmega128c3, atxmega128d3, atxmega128d4, atxmega192a3, atxmega192a3u, atxmega192c3, atxmega192d3, atxmega256a3, atxmega256a3u, atxmega256a3b, atxmega256a3bu, atxmega256c3, atxmega256d3, atxmega384c3, atxmega384d3, atxmega128a1, atxmega128a1u, atxmega128a4u, attiny4, attiny5, attiny9, attiny10, attiny20, attiny40, attiny102, attiny104 E[12:54:19.163] Indexing C:\Users\per\AppData\Local\Arduino15\packages\arduino\hardware\megaavr\1.8.7\cores\arduino\WInterrupts.cpp failed: Couldn't build compiler instance ``` --- The equivalent error occurs when using boards with other microcontrollers in this architecture family. --- This is actually a deficiency in lower level tools ([clangd](https://clangd.llvm.org/) via [Arduino Language Server](https://github.com/arduino/arduino-language-server)), and not actually anything to do with the Arduino IDE 2.x code base.

Hopefully a solution will be found.

Thank you! Turns out I just hade to change the preferences

Willem43 · April 14, 2021, 12:08pm

Thanks for the details. I have reported the problem:
Problem Preferences Quick Suggestions tick box. #313

The popups can be of assistance, so I like them. However they are mostly positioned covering the related text. I found if I change the Hover Delay to, say 1200ms, it gives time to position the cursor and edit without the popup appearing. By hovering for a heart beat or two, the popup appears.

I noticed two issues with this.

When opening a new tab the original 300ms is used - not the newly specified 1200ms. You need to reset the value and enter 1200 again and all tabs are now obeying the 1200ms. Also closing and opening the sketch all the tabs again use 300ms - ignoring the changed delay.
If I start a header (.h) or a .cpp file in a new tab (remember to include arduino.h) the popup position is perfect, right above or right below the selected text. Only .ino files/tabs seem to have the positioning problem.

Could someone please check and confirm this.

Willem.

conclusion: resolved topic: code type: imperfection

**Describe the bug** The Preferences Quick Suggestions tick box does not reflec…t the current status. When opening Preferences it is always cleared. If ticked, it actually toggles the current status and will be cleared again when next time Preferences is opened. **To Reproduce** Steps to reproduce the behavior: 1. Open File/Preferences. The Editor Quick Suggestions tick box is cleared. 2. Click on the tick box. The blue arrow arears. Close Preferences. 3. Type text and check if Quick Suggestions are shown. 4. Open Preferences - the tick box is cleared. 5. Click it again and check if Quick Suggestions has changed. 6. The tick box will again be cleared when opening Preferences. **Expected behavior** Tick box should reflect the current status of Quick Suggestions. **Desktop (please complete the following information):** - OS: Windows 10 Pro

Originally from here: https://github.com/arduino/arduino-ide/issues/21#issuecomm…ent-780414532 The LS provides incorrect line information for symbols. Due to the incorrect line info, the overlay widget hides the symbol, and it is not possible to right-click on the symbol. ![screencast 2021-02-17 10-45-37](https://user-images.githubusercontent.com/1405703/108186232-68b2e480-710d-11eb-8c28-d76841426b74.gif) Let assume the following sketch and the `<|>` as the line information: ```cpp /* Blink Turns an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used. If you want to know what pin the on-board LED is connected to on your Arduino model, check the Technical Specs of your board at: https://www.arduino.cc/en/Main/Products modified 8 May 2014 by Scott Fitzgerald modified 2 Sep 2016 by Arturo Guadalupi modified 8 Sep 2016 by Colby Newman This example code is in the public domain. http://www.arduino.cc/en/Tutorial/Blink */ // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin LED_BUILTI N as an output. pin<|>Mode(LED_BUILTIN, OUTPUT); } // the loop function runs over and over again forever void loop() { digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second } ``` LS returns with this: ```json { "range": { "startLineNumber": 35, "startColumn": 3, "endLineNumber": 35, "endColumn": 10 }, "contents": [ { "value": "### function `pinMode` \n\n---\n→ `void` \nParameters: \n- `uint8_t pin`\n- `uint8_t mode`\n\n---\n```cpp\nvoid pinMode(uint8_t pin, uint8_t mode)\n```" } ] } ``` `"startLineNumber": 35` is incorrect, it should be `28.`

Sounds like you're already working on your next bug report! This sort of feedback is very valuable. It's the thing that will only be noticed when you have a lot of users trying out every possible thing you could imagine. Probably a small group of testers would never think to change from the default value. This is why it's very good that Arduino decided to release Arduino IDE 2.x now in its beta stage rather than waiting until a production release was ready.

The non-.ino files don't undergo any sketch preprocessing so the line numbers don't change. I'd guess that's the reason for the difference.
