Hi there,

First, thank for this plugin, really helpful.

I would like to report an issue: XmlPullParserException: only whitespace content allowed before start tag and not O ...

At first, I thought maybe my yaml file was invalid, but checked it with YAMLLint and it said it's valid.

Versions & OS

Sass-lint-plugin: 1.10.2
IntelliJ IDEA 2017.1 Build #IU-171.3780.107, built on March 22, 2017
JRE: 1.8.0_112-release-736-b13 amd64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Linux 4.8.0-46-generic

Context

sass-lint config:

• Checked the Use specific config file , and verified the sass-lint.yml with YAMLLint, it's valid.
• Filled the Path to sass-lint bin & Node interpreter

I just open any scss file, and when it starts analyzing the file, Intellij pops a notification saying an error occured with sass-lint-plugin.

Stacktrace

Here is the complete stacktrace if it can help =)

Sample SCSS file & YAML config

SCSS file throwing the error (but it occurs on every filed I opened)

@import 'mixins/label';

.label {
    display: inline-block;
	font-size: $font-size-base;
	padding: $padding-base-vertical/2 $padding-base-horizontal;

	+ .label {
		margin-left: $padding-base-vertical/2;
	}
}

.label-default {
  @include label-variant($label-default-bg);
}

.label-primary {
  @include label-variant($label-primary-bg);
}

.label-success {
  @include label-variant($label-success-bg);
}

.label-info {
  @include label-variant($label-info-bg);
}

.label-warning {
  @include label-variant($label-warning-bg);
}

.label-danger {
  @include label-variant($label-danger-bg);
}

.mui-label-remove {
	padding-left: $padding-base-horizontal;

	cursor: pointer;
}

Yaml config I pointed to in sass-lint-plugin config in Intellij:

Any clue ? =)

Thanks in advance, and again, great work !

Whenever I start Webstorm, I'm getting an error that I'm having trouble making sense of

It appears the linter isn't working on my machine. My settings are as follows:

My sass-lint is version 1.9.1.

Have others run into this error? If this is an issue w/ my configuration of the plugin, it would be helpful to have a more descriptive error message if possible. Thanks!

I have configured the plugin as shown below:

Because of the red bar at the bottom I assume there is an error, but I can't find anything in the log or the command line output. When I open a .scss file the plugin runs a node command (for example:
2016-09-04 18:05:11,749 [ 194813] INFO - #com.wix.nodejs.NodeRunner - Running node command: /usr/bin/node /home/zoehneto/IdeaProjects/tumblr-reader/node_modules/sass-lint/bin/sass-lint.js src/app/app.component.scss -v -q -c /home/zoehneto/IdeaProjects/tumblr-reader/.sass-lint.yml --format checkstyle
) which does return issues (in this case:
<?xml version="1.0" encoding="utf-8"?><checkstyle version="4.3"><file name="src/app/app.component.scss"><error line="14" column="26" severity="error" message="Color literals such as &apos;lightgrey&apos; should only be used in variable declarations (no-color-literals)" source="eslint.rules.no-color-literals" /><error line="21" column="10" severity="error" message="Color literals such as &apos;#6E6E6E&apos; should only be used in variable declarations (no-color-literals)" source="eslint.rules.no-color-literals" /></file></checkstyle>
) but these errors don't show up in the editor window.

Without a .yml file the default inspection errors show up in the editor.
With a .yml file regardless of letting the plugin look for it by itself or specifically configuring which .yml file to use, it doesn't give any inspection errors.

Changing node interpreter version (5.11, 6.0, 6.2, 6.5) doesn't help either.

A Vue project can have single-file components with the .vue extension, and these can contain <style> sections. Would it be possible for the plugin to parse the <style lang="scss"> sections of .vue files?

Currently, I can use sourceboat/sass-lint-vue to do this from the command line — but it's much more convenient to have the violations highlighted right there in the editor 😀

I believe Sass Lint is having trouble with IDE 2016.2 EAP. The plugin is installed, but I've seen the IDE have trouble running it -- could be node or sass-lint config paths get lost (see stack trace below). I have the latest Node and sass-lint, and have configured paths to them under IDE's Preferences window, Other Settings, Sass Lint.

Additionally, Sass Lint in a project doesn't show a config panel (the panel reads "Select a configuration element...") which means you cannot provide the path to a local .sass-config.yml file.

1. Error shown on scss file, e.g. indentation expect 2 got 4
2. change .sass-lint.yml, to turn indention rule off, e.g. indentation: 0
3. Error remains on scss file
4. Disable sass-lint plugin. Apply.
5. Enable sass-lint plugin. Apply.
6. Error has gone from scss file

Is this expected behaviour? I would hope scss-lint.yml changes would be applied immediately.

I've set node and sass-lint binaries, but getting a hint

/usr/bin/env: 'node': No such file or directory

Though plugin is working, but the warning is annoying

Plugin crashes at startup, PHPStorm version 2016.2 EAP

Created two files:

test.scss - here Sass Lint works properly
test.sass - here Sass Lint doesn't work

Please see the screenshots attached.

On the command line sass-lint.js reports the errors correctly for both files:

Great plugin, but since upgrading to PhpStorm 2016.2 we're experiencing the following error after configuring the Sass Lint plugin and opening Storm's settings afterwards:

IllegalArgumentException: cannot create configurable component: path doesn't exist

Also .idea/sasslintPlugin.xml loses it's path configuration after that.

Our work-around was to change the XML file's permission to read-only, but maybe there's a better way to fix this in a future update. Thanks! :)

Try to find sass-lint binary automatically following this rules:

1) <PROJECT_ROOT>/node_modules/.bin/sass-lint
2) <PATH>/sass-lint

Also, keep the option to allow the user to manually switch to a different one.

It appears it's not finding my config file in the following setup:

• packages/
  • client/
    • node_modules/.bin/sass-lint
    • package.json (has sass-lint)
    • .sass-lint.yml

When I copy the config file to my project root it does pick up the rules.

Today i've got an Fatal Error within PHPStorm. Sass-lint did not work until now. Might be related to #12

We have strict linting rules on our project, they all are errors instead of warning, so pre-commit hook may fail on error. But plugin acts strange in this case: instead of highlighting errors it shows balloon with almost no information: "Error: 6 errors were detected in ...".

It doesn't make any sense.

Check https://github.com/sasstools/sass-lint#configuring

Sass-lint can be configured from a .sass-lint.yml or .sasslintrc file in your project.

It will be better to have both options.

Plugin does not load with Webstorm 2018.3, I get the following error:

This is kind of weirdly-acting. I get a red-letter IDE Error toast every time opening build 173.3415.21 (and I think previous one also, but recently, anyway. This goes away in not many seconds, if it remains in the logs. If I click it in time, I get informed about you, with the stack trace below.

This doesn't happen on sccs-lint; it's clean. So should be an easy find, would think. I looked through the .idea and main WebStorm config files; didn't see any double representations of sass-lint, though possibly that's because the problem resides in a binary db file. Uninstall/Reinstall didn't help in any way -- cheers.

Is it possible to implement auto-sort properties feature, which will be shown as option in list of solutions ?
(SCSS Lint Plugin has this - so maybe it is possible to transfer ?)
