Changing the default Arduino New Project Template

1

Hi,

When I start a new Arduino project, i would prefer the template be the main.cpp found in the arduino cores directory (i.e. based on main() instead of setup() & loop().). I’ve searched everywhere and cannot find out how to do this…

I did learn how to use snippets… a pretty cool feature; but I would still prefer it if I could somehow change the starting template.

can someone point me in the right direction?

thanks,
G

Currently, we don’t provide this configuration. However, this feature request will help here

Thanks for the quick feedback. In the mean time, I will just drag my template into the project src file when i create a new project.

I wonder who put the code there in the first place - EVERY NEW project has this in the main.cpp:

#include <Arduino.h>

// put function declarations here:
int myFunction(int, int);

void setup() {
  // put your setup code here, to run once:
  int result = myFunction(2, 3);
}

void loop() {
  // put your main code here, to run repeatedly:
}

// put function definitions here:
int myFunction(int x, int y) {
  return x + y;
}

Where does this code come from … I’m NOT aware of typing that at any time !

The PlatformIO core autocreates it.

???
AND … ???

My problem is - can I change it ?
If so, where do I do it ?

There is no functionality for that to be user-changable. It’s hardcoded in the PlatformIO core code. The above linked issue tracks that.

Why not use the power of VSCode?
You can create custom snippets!
You can find instructions here:

  1. Watch the Video
  2. Edit the cpp.json and add this:
	  "Arduino default code" : {
		"prefix" : "adc",
		"body" : [
			"#include <Arduino.h>",
			"",
			"void setup() {",
			" Serial.begin(115200);",
			" Serial.println(\"Hello World\");",
			"}",
			"",
			"void loop() {",
			"}"
		]
	}
  1. If you have created a new PIO project:
  • Press CTRL+A on your keyboard to select everything
  • Enter “adc” (or the prefix you have used)
  • Press ENTER

This will only cost you 5 keystrokes (if you count the combination CTRL+A as one :wink: )
