gulp-scss-lint
Lint your
.scss
files
Install
npm install gulp-scss-lint --save-dev
This plugin requires Ruby and scss-lint
gem install scss_lint
Usage
gulpfile.js
var scsslint = require('gulp-scss-lint');
gulp.task('scss-lint', function() {
return gulp.src('/scss/*.scss')
.pipe(scsslint());
});
Api
config
- Type:
String
- Default: default scss-lint config file.
scsslint({
'config': 'lint.yml'
});
bundleExec
- Type:
Boolean
- Default:
false
If your gem is installed via bundler, then set this option to true
scsslint({
'bundleExec': true
});
reporterOutput
- Type:
String
- Default:
null
If you want to save the report to a file then set reporterOutput with a file name
scsslint({
'reporterOutput': 'scssReport.json'
});
reporterOutputFormat
- Type:
String
- Default:
JSON
- Values:
JSON
orCheckstyle
gulp.src(['**/*.scss'])
.pipe(scsslint({
'reporterOutputFormat': 'Checkstyle',
}))
filePipeOutput
- Type:
String
- Default:
null
If you want the pipe return a report file instead of the .scss
file then set filePipeOutput with a filename
//xml
gulp.src(['**/*.scss'])
.pipe(scsslint({
'reporterOutputFormat': 'Checkstyle',
'filePipeOutput': 'scssReport.xml'
}))
.pipe(gulp.dest('./reports'))
//json
gulp.src(['**/*.scss'])
.pipe(scsslint({
'filePipeOutput': 'scssReport.json'
}))
.pipe(gulp.dest('./reports'))
maxBuffer
- Type: Number or Boolean
- Default: 300 * 1024
Set maxBuffer for the child_process.exec process. If you get a maxBuffer exceeded
error, set it with a higher number. maxBuffer specifies the largest amount of data allowed on stdout or stderr.
gulp.src(['**/*.scss'])
.pipe(scsslint({
'maxBuffer': 307200
}))
.pipe(gulp.dest('./reports'))
endless
- Type: Boolean
- Default: false
If you use gulp-watch set endless to true.
sync
- Type: Boolean
- Default: sync
scss-lint
will be executed in sequence.
verbose
- Type: Boolean
- Default: false
If you want to see the executed scss-lint command for debugging purposes, set this to true.
Glob pattern without gulp.src
var scsslint = require('gulp-scss-lint');
gulp.task('scss-lint', function() {
return scsslint({
shell: 'bash', // your shell must support glob
src: '**/*.scss'
});
});
Excluding
To exclude files you should use the gulp.src ignore format '!filePath''
gulp.src(['/scss/*.scss', '!/scss/vendor/**/*.scss'])
.pipe(scsslint({'config': 'lint.yml'}));
Or you should use gulp-filter
var scsslint = require('gulp-scss-lint');
var gulpFilter = require('gulp-filter');
gulp.task('scss-lint', function() {
var scssFilter = gulpFilter('/scss/vendor/**/*.scss');
return gulp.src('/scss/*.scss')
.pipe(scssFilter)
.pipe(scsslint())
.pipe(scssFilter.restore());
});
Lint only modified files
You should use gulp-cached
In this example, without the gulp-cached plugin, every time you save a .scss
file the scss-lint plugin will check all your files. In case you have gulp-cached plugin, it will only check the modified files.
var scsslint = require('gulp-scss-lint');
var cache = require('gulp-cached');
gulp.task('scss-lint', function() {
return gulp.src('/scss/*.scss')
.pipe(cache('scsslint'))
.pipe(scsslint());
});
gulp.task('watch', function() {
gulp.watch('/scss/*.scss', ['scss-lint']);
});
Results
Adds the following properties to the file object:
file.scsslint = {
'success': false,
'errors': 0,
'warnings': 1,
'issues': [
{
'line': 123,
'column': 10,
'severity': 'warning', // or `error`
'reason': 'a description of the error'
}
]
};
The issues have the same parameters that scss-lint
Custom reporter
You can replace the default console log by a custom output with customReport
. customReport function will be called for each file that includes the lint results See result params
var scsslint = require('gulp-scss-lint');
var myCustomReporter = function(file) {
if (!file.scsslint.success) {
gutil.log(file.scsslint.issues.length + ' issues found in ' + file.path);
}
};
gulp.task('scss-lint', function() {
return gulp.src('/scss/*.scss')
.pipe(scsslint({
customReport: myCustomReporter
}))
});
You can even throw an exception
var scsslint = require('gulp-scss-lint');
var myCustomReporter = function(file, stream) {
if (!file.scsslint.success) {
stream.emit('error', new gutil.PluginError("scss-lint", "some error"));
}
};
gulp.task('scss-lint', function() {
return gulp.src('/scss/*.scss')
.pipe(scsslint({
customReport: myCustomReporter
}))
});
Default reporter
This is an example from the default reporter output
[20:55:10] 3 issues found in test/fixtures/invalid.scss
[20:55:10] test/fixtures/invalid.scss:1 [W] IdSelector: Avoid using id selectors
[20:55:10] test/fixtures/invalid.scss:2 [W] Indentation: Line should be indented 2 spaces, but was indented 0 spaces
[20:55:10] test/fixtures/invalid.scss:2 [W] EmptyRule: Empty rule
Fail reporter
If you want the task to fail when "scss-lint" was not a success then call failReporter
after the scsslint call.
This example will log the issues as usual and then fails if there is any issue.
var scsslint = require('gulp-scss-lint');
gulp.task('scss-lint', function() {
return gulp.src('/scss/*.scss')
.pipe(scsslint())
.pipe(scsslint.failReporter())
});
if you just want failReporter
to fail just with errors pass the 'E' string
var scsslint = require('gulp-scss-lint');
gulp.task('scss-lint', function() {
return gulp.src('/scss/*.scss')
.pipe(scsslint())
.pipe(scsslint.failReporter('E'))
});
Testing
To test you must first have scss-lint
installed globally using
gem install scss_lint
as well as via bundler using bundle install
.
