gulp-jsvalidate's Issues

Show file path and/or filename?

Great plugin overall! I like that the line number from the invalid file is listed in the error.

However, is there anyway to also show the path and or name of the file that the validation failed on?

Shows @import statements as error

I was trying to use gulp-jsvalidate to find errors in my js files. Although, I found that when I use @import statements, it recognize that statement as error.

As soon as I comment out that statement it works fine.
May be I don't know some settings.
Can you please help me out on this.

Can't pipe jsvalidate with other plugins?

I've tried to do that:

module.exports = function() {

 return require('gulp').src( files )
  .pipe( require('gulp-jsvalidate')() )
  .pipe( require('gulp-jscs')() )
  .pipe( jshint('.jshintrc') )
  .pipe( jshint.reporter('jshint-stylish') 
}

but if jsvalidate finds an error, it breaks everything.

I was able to do that though:

module.exports = function() {

 return require('gulp').src( files )
  .pipe( require('gulp-jscs')() )
  .pipe( jshint('.jshintrc') )
  .pipe( jshint.reporter('jshint-stylish') 
}

And this is what I do now:

var files = ['app.js', 'lib.js']

module.exports = {

  jsvalidate: function() {
    return require('gulp').src( files )
      .pipe( require('gulp-jsvalidate')() )
  },

  jscs: function() {
    return require('gulp').src( files )
      .pipe( require('gulp-jscs')() )
  },

  jshint: function() {
    var jshint = require('gulp-jshint')

    return require('gulp').src( files )
      .pipe( jshint('.jshintrc') )
      .pipe( jshint.reporter('jshint-stylish') )
  }

}

with

gulp.task('jshint', require(path + 'validate').jshint)
gulp.task('jsvalidate', require(path + 'validate').jsvalidate)
gulp.task('jscs', require(path + 'validate').jscs)
gulp.task('validate', ['jsvalidate', 'jshint', 'jscs'])

Any idea how to make my first try work?

Doesn't support ES 6 spread.

This plugin doesn't support es6 features. I think because of facebook is gonna deprecate esprima.
