[Solved] Auto completion not working on Arduino 2.1

dj_math · 2023-04-27T20:54:15.711Z

It seems that the auto completion isn't working, can't get any functions like shiftOut, or functions in a library.
The only things I get are keywords, they are suggested on the auto completion list.
Also, I can't see infos on a variable/fonction, so I'm unable to put the right parameter without doing an internet research, see what the function returns and what type the variable is.
The Editor Quick Suggestions is enabled in Preferences.
Is there a way to fix it at home ?

The following link says:

"... trigger the autocomplete feature by pressing CTRL + spacebar..."

docs.arduino.cc

The Autocomplete Feature | Arduino Documentation

Learn how the autocomplete feature works with Arduino IDE 2, and how it can help speed up your development time.

The following link says:

It doesn't work when I write analog (for analogWrite), it says "no suggestions" when I do CTRL + spacebar

Perhaps @ptillisch can resolve this...

Hi @dj_math. There is a known bug in Arduino IDE 2.1.0 that causes this to happen when the sketch is stored on a drive other than C:\ on your computer:

github.com/arduino/arduino-cli

`compile` command fails when sketch on different drive from custom build path

os: windows topic: code type: imperfection

### Describe the problem Under the following conditions: - A custom build …path is set via the `--build-path` flag. - The build path is on a different drive from the sketch. compilation fails: ```text Error during build: Cannot find build path: Rel: can't make C:\Users\per\AppData\Local\Temp\build-path relative to E:\FooSketch ``` ### To reproduce ```text $ arduino-cli version arduino-cli.exe Version: git-snapshot Commit: 2c2a5cc6 Date: 2023-04-24T05:04:04Z $ arduino-cli sketch new "e:/FooSketch" Sketch created in: e:\FooSketch $ arduino-cli compile --build-path "c:/Users/per/AppData/Local/Temp/build-path" --fqbn arduino:avr:uno "e:/FooSketch" Error during build: Cannot find build path: Rel: can't make c:\Users\per\AppData\Local\Temp\build-path relative to E:\FooSketch ``` ### Expected behavior Compilation is possible when custom build path is on a different drive from sketch. ### Arduino CLI version 2c2a5cc6 ### Operating system Windows ### Operating system version 11 ### Additional context I bisected the regression to 78bfa744dc0fbdd04d385e56545027e824a3102f --- I was not able to reproduce the fault on Linux or macOS --- The fault does not occur when `--build-path` is not used in the command even when that command uses a default build path on a different drive from the sketch. --- The fault also occurs when using the gRPC interface. --- Although the use of `--build-path` in command line commands is probably not so common, custom build paths are used for the compile operations ran by Arduino IDE 2.x to generate the compilation database for Arduino Language Server, which makes the regression more impactful. --- Originally reported at: https://forum.arduino.cc/t/data-item-properties-in-ide-2-1/1118282 #### Additional reports - https://forum.arduino.cc/t/data-item-properties-in-ide-2-1/1118282/9 - https://forum.pjrc.com/threads/72643-Issues-with-Arduino-IDE-2-1-and-Teensy-4-1#post_324742 - https://forum.arduino.cc/t/code-hints-missing/1119231 - https://forum.arduino.cc/t/upgrading-2-0-3-to-2-1-0-function-f12-and-alt-f12-not-present-on-menu/1118731 - https://forum.arduino.cc/t/f12-qui-ne-fonctionne-pas/1119169/1 - https://forum.arduino.cc/t/f12-qui-ne-fonctionne-pas/1119169/6 - https://forum.arduino.cc/t/code-hints-missing/1119231/4 - https://github.com/arduino/arduino-ide/issues/2034 ### Issue checklist - [X] I searched for previous reports in [the issue tracker](https://github.com/arduino/arduino-cli/issues?q=) - [X] I verified the problem still occurs when using the [nightly build](https://arduino.github.io/arduino-cli/dev/installation/#nightly-builds) - [X] My report contains all necessary details

The workaround is to store your sketches on your C:\ drive.

Unlucky for us, moving sketches from another drive to anywhere in C:\ drive didn't fix the bug, still don't have auto completion. Should I recreate a sketch and save it anywhere on C:\ drive ? Or return back to a 2.0.x version ?

EDIT : Auto completion returns ! I simply forgot to select a board, but YES, moving every sketch to C drive FIX THE BUG !

I tried to mount D:/ drive in a folder on C:/

learn.microsoft.com

Assign a mount point folder path to a drive.

Learn how to mount a drive as a folder rather than a letter and how to unmount a drive from a folder.

Unfortunately it did not help.

I just moved my Arduino folder from D:\ to C:\Documents.
But ... did you try to move the D drive to C drive ? Or I may missunderstand.
