How do other folders use the default icon?

[一代咩神]

I created a folder called inc.
I want this folder to have the same icon as [folder name: include], how do I set it?

I'm not sure what you mean by that. Could you elaborate? Possibly with a screenshot?

how do I set it?

All icon customisation is achieved using CSS. To replicate the default styling applied to directories, you'd use:

.directory > .header > .icon{
	&[data-name="inc"]:before{
		font-family: "Octicons Regular";
		font-size: 16px;
		content: "\f016";
	}
}

Simply, I hope that the icons of these two folders are the same.

How to set them in IDEA ?

I don't know, because the IDEA port isn't something I have control over. You're better off reporting this to the proper repository. 😉
