Changes to programmers.txt are not recognized #591

Describe the problem

🐛 The first time a board is selected, its programmers are cached by the IDE. After that, changes to the programmers.txt configuration file of the boards platform are not reflected in the IDE's Tools > Programmer menu.

To reproduce

Close all Arduino IDE windows.
Clear the Programmer menu cache by deleting the C:\Users\<user name>\AppData\Roaming\arduino-ide (Windows) or ~/.config/arduino-ide (Linux) folder.
This is done in order to ensure there are boards available without a cached Programmer menu to compare with the board that has a cache.
Start the Arduino IDE.
Use Boards Manager to install "Arduino AVR Boards" (if it is not already installed).
Select Tools > Board > Arduino AVR Board > Arduino Uno from the Arduino IDE menus.
The Programmer menu entries have now been cached for the "Arduino Uno" board, but not for the other boards of the "Arduino AVR Boards" platform that have not yet been selected in the IDE.
Open the Tools > Programmer menu and take note of the programmers listed there:
Close all Arduino IDE windows
Open C:\Users\<user name>\AppData\Local\Arduino15\packages\arduino\hardware\avr\<platform version>\programmers.txt (Windows) or ~/.arduino15/packages/arduino/hardware/avr/<platform version>/programmers.txt (Linux) in a text editor.
Add a new programmer definition to the file by adding the following lines to the file:
```
foo.name=Added Programmer
foo.program.tool=avrdude
```
Modify a programmer definition by changing this line:
```
avrisp.name=AVR ISP
```
to this:
```
avrisp.name=Modified Programmer
```

Remove a programmer definition by deleting these lines:

avrispmkii.name=AVRISP mkII
avrispmkii.communication=usb
avrispmkii.protocol=stk500v2
avrispmkii.program.protocol=stk500v2
avrispmkii.program.tool=avrdude
avrispmkii.program.extra_params=-Pusb

Save the file.
Start the Arduino IDE.
Select Tools > Board > Arduino AVR Board > Arduino Uno from the Arduino IDE menus.
Open the Tools > Programmer menu.
🐛 The menu contents don't reflect any of the changes that were made to programmers.txt:
Select Tools > Board > Arduino AVR Board > Arduino Leonardo from the Arduino IDE menus.
This is the first time selecting this board so its Programmers menu cache is populated now.
Open the Tools > Programmer menu.
🙂 The menu contents reflect the changes that were made to programmers.txt:
Select Tools > Board > Arduino AVR Board > Arduino Uno from the Arduino IDE menus.
Select File > Save As... from the Arduino IDE menus.
Save the sketch to any convenient name and location.
ⓘ The purpose of this step is to allow the sketch with the incorrect associated state metadata to be opened after restarting the IDE.
Select File > New Sketch from the Arduino IDE menus.
Open the Tools > Programmer menu.
🙂 The menu contents reflect the changes that were made to programmers.txt.
Close all Arduino IDE windows.
Delete the "user data" folder at the following path:
- Windows:
```
C:\Users\<username>\AppData\Roaming\arduino-ide\
```
  (where <username> is your Windows username)
  ❗ If looking for it with your file manager or command line, note that the AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".
- Linux:
```
/home/<username>/.config/arduino-ide/
```
  (where <username> is your Linux username)
  ❗ The .config folder may be hidden by default in your file manager and terminal.
- macOS:
```
/Users/<username>/Library/Application Support/arduino-ide/
```
  (where <username> is your macOS username)
  ❗ The Library folder is hidden by default. You can make it visible by pressing the Command+Shift+. keyboard shortcut.
⚠ Please be very careful when deleting things from your computer. When in doubt, back up!
Start the Arduino IDE.
Select Tools > Board > Arduino AVR Board > Arduino Uno from the Arduino IDE menus.
Open the Tools > Programmer menu.
🙂 The menu contents reflect the changes that were made to programmers.txt.

Expected behavior

Tools > Programmer menu always reflects the contents of the programmers.txt files at the time the Arduino IDE was started, just as it is in the classic Arduino IDE.

Additional Reports

Workaround

Select File > Quit (or Arduino > Quit Arduino for macOS users) from the Arduino IDE menus if it is running.
Delete the following folder to force Arduino IDE to update the Tools > Programmer menu data:
- Windows:
```
C:\Users\<username>\AppData\Roaming\arduino-ide\
```
  (where <username> is your Windows username)
  ❗ If looking for it with your file manager or command line, note that the AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".
- Linux:
```
/home/<username>/.config/arduino-ide/
```
  (where <username> is your Linux username)
  ❗ The .config folder may be hidden by default in your file manager and terminal.
- macOS:
```
/Users/<username>/Library/Application Support/arduino-ide/
```
  (where <username> is your macOS username)
  ❗ The Library folder is hidden by default. You can make it visible by pressing the Command+Shift+. keyboard shortcut.
⚠ Please be very careful when deleting things from your computer. When in doubt, back up!
Start Arduino IDE.

You should now see the expected list of programmers under the Tools > Programmer menu.

Issue checklist

I searched for previous reports in the issue tracker
I verified the problem still occurs when using the latest nightly build
My report contains all necessary details

The text was updated successfully, but these errors were encountered:

dlitz · 2023-06-05T22:54:11Z

I seem to be able to get the programmers list to refresh by doing the following:

Running arduino-ide --open-devtools to open the Chromium Developer Tools
Going to Application -> Local Storage -> file://
Searching for "programmers" (it should return some keys starting with theia:.arduinoIDE-configOptions-arduino:)
Deleting the entry/entries for the board(s) I'm using.
Quitting and restarting Arduino IDE
