CSS properties in comments increase indefinitely.

[ddryo]

What minimal example or steps are needed to reproduce the bug?

I use VS Code's stylelint plugin to automatically run fix when saving a file.

However, at this time, for some reason, the CSS property name being purchased within the comment is copied to the end of the comment. (There was no problem when I fixed it with the stylelint --fix command.

.test {
	color: red;
	background-color: #fff;

	// background-color: blue;
}

// .hoge{
//     color:yellow;
// }

https://github.com/stylelint/stylelint/assets/31400297/3ce325bf-b7a4-4fef-96da-58cfba620a8a

Also, this problem has been occurring since updating stylelint from v15 to v16.

What minimal configuration is needed to reproduce the bug?

.stylelintrc.cjs

module.exports = {
	extends: [
		'stylelint-config-recommended-scss',
	],
};

How did you run Stylelint?

This problem seems to occur when you use a VS Code extension to automatically format a file when saving it.

Which Stylelint-related dependencies are you using?

{
    "stylelint": "^16.2.0",
    "stylelint-config-recommended-scss": "^14.0.0",
}

What did you expect to happen?

I just want to save the file normally.

What actually happened?

CSS properties in comments increase indefinitely.

Do you have a proposal to fix the bug?

No response

@ddryo Thanks for the report with a real reproduction video. Probably, this is the same problem as stylelint/vscode-stylelint#490.

[ybiquitous]

@ddryo Can you provide your .vscode/settings.json?

[ddryo]

Yes, here is the setting data.

{
	"html.format.enable": false,
	"javascript.format.enable": false,
	"css.format.enable": false,
	"eslint.format.enable": false,
}

[ybiquitous]

Thanks for the quick response. But I cannot reproduce the problem for some reason. 🤔

Can you reproduce it on your console (CLI) instead? E.g.

npx stylelint test.scss --fix

[ddryo]

This problem occurred when tested in an environment with only the following two files

pckage.json

{
	"name": "stylelint-test",
	"version": "1.0",
	"description": "",
	"main": "dist/index.js",
	"module": "dist/index.js",
	"scripts": {},
	"private": true,
	"license": "MIT",
	"devDependencies": {
		"stylelint": "^16.2.0"
	}
}

test.scss

.test {
	color: red;
	background-color: #fff;

	// background-color: blue;
	
}

// .hoge{
//     color:yellow;
// }

[ddryo]

@ybiquitous No, the command does not reproduce.

As explained at the beginning, this only occurs when auto-formatting with VS Code extensions.

[ddryo]

this plugin https://marketplace.visualstudio.com/items?itemName=stylelint.vscode-stylelint

[ddryo]

Come to think of it, I use pnpm.

node is v18.19.0.

[ybiquitous]

@ddryo Thanks for the minimum reproduction. This problem seems specific to the VSCode extension, so I'll transfer this issue to https://github.com/stylelint/vscode-stylelint.

[ddryo]

Additional verification.

It does not occur in stylelint v.15.11.0, it occurs starting from v.16.0.0.

[ybiquitous]

Just to confirm, does this problem happen without the config file (.stylelintrc.cjs)?

[ddryo]

No, this occurred with or without .stylelintrc.cjs.

[ddryo]

If I wanted to use stylelint-prettier v5 or later, I had to use stylelint v16 or later to get it to work, so I updated to stylelint v16 and encountered this bug.

At first I thought it might be due to prettier, but as I described above, it also occurred in an environment with only 2 files (counted before node_module installation). So I think VS Code plugin and stylelint v16 are incompatible.

[ybiquitous]

It's strange. I cannot reproduce this problem for now with the 2 files and node_modules. 🤔

[ybiquitous]

So I think VS Code plugin and stylelint v16 are incompatible.

It may be correct. The main branch hasn't tested v16 yet:

https://github.com/stylelint/vscode-stylelint/blob/39e7c76070bb5cfe678ace65de3a30d69e092196/package.json#L249

[ybiquitous]

I think there is no problem if Stylelint and the extension are configured properly. The following files are in my environment:

stylelint.config.mjs:

export default {
  customSyntax: "postcss-scss",
  rules: {
    "function-name-case": "upper",
  },
};

package.json (need to run npm install):

{
  "devDependencies": {
    "postcss-scss": "^4.0.9",
    "stylelint": "^16.2.0"
  }
}

.vscode/settings.json:

{
  "stylelint.validate": ["css", "scss"],
  "editor.codeActionsOnSave": {
    "source.fixAll.stylelint": true
  }
}

test.scss:

a {
  color: calc(1 + 2);
}

When the file above is saved, it's automatically converted to:

- color: calc(1 + 2);
+ color: CALC(1 + 2);

[ddryo]

Thank you very much！ However, the bug did occur...

https://github.com/stylelint/vscode-stylelint/assets/31400297/a7360508-0fe6-49e6-aa41-550a9ca9d520

[ybiquitous]

Hum, I cannot reproduce unintentionally inserted comments... 🤔

I wonder if .vscode/settings.json is different. Is your .vscode/settings.json the same as mine? ⬇️

{
  "stylelint.validate": ["css", "scss"],
  "editor.codeActionsOnSave": {
    "source.fixAll.stylelint": true
  }
}

[ddryo]

Yes. But for some reason, when I reload the project, the true part seems to be automatically switched to "explicit" as shown below.

{
  "stylelint.validate": ["css", "scss"],
  "editor.codeActionsOnSave": {
    "source.fixAll.stylelint": "explicit"
  }
}

[ybiquitous]

The behavior doesn't seem to change between true and explicit. See https://code.visualstudio.com/updates/v1_85#_code-actions-on-save-and-auto

[ybiquitous]

FYI, I've just opened PR #492 to reduce confusion in README.

在stylelint16.x中我也遇到了同样的问题，格式化的时候，它会无限的追加注释

"stylelint": "^16.2.0",
"stylelint-config-recess-order": "^4.4.0",
"stylelint-config-standard-scss": "^13.0.0"
