Grunt-complexity on all the files in a directory - gruntjs

Question

I'd like to run Grunt-Complexity on all the files in a directory?
I'd like to get this kind of output.
Is there a way?
My js files are all under a subdirectory called "js".
Here's my gruntfile:
/*global module:false*/
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
// Task configuration.
complexity: {
generic: {
src: ['grunt.js', 'js/*'],
//exclude: ['doNotTest.js'],
options: {
breakOnErrors: false,
jsLintXML: 'report.xml', // create XML JSLint-like report
checkstyleXML: 'checkstyle.xml', // create checkstyle report
pmdXML: 'pmd.xml', // create pmd report
errorsOnly: false, // show only maintainability errors
cyclomatic: [3, 7, 12], // or optionally a single value, like 3
halstead: [8, 13, 20], // or optionally a single value, like 8
maintainability: 100,
hideComplexFunctions: false, // only display maintainability
broadcast: false // broadcast data over event-bus
}
}
}
});
// These plugins provide necessary tasks.
grunt.loadNpmTasks('grunt-complexity');
// Default task.
grunt.registerTask('default', 'complexity');
};
I'm simply calling this by typing
grunt
from the command line.
then if I type this
grunt complexity js/*
I get
Warning: Task "js/AgencyMediaController.js" not found. Use --force to continue.
Aborted due to warnings.
And AgencyMediaController.js is the first file in my js directory. So it's having a look and listing the files, but then it crashes.
Thanx!

example:
for all js file in JS folder:
src: ['js/**/*.js']
for ass .scss files in scss folder:
src: ['scss/**/*.scss']
I suggest for you create a config for your src folder can be easy in future folder changes in future projects:
sample:
var src;
config.src = src = {
sassMain : 'scss/main.scss',
distFolder : 'public/stylesheets/lovelycss.dist.css',
devFolder : 'public/stylesheets/lovelycss.dev.css',
libFolder : 'lib/**/*.js',
sassFolder : 'scss/**/*.scss',
spriteCssFolder : 'scss/helpers/_sprite.scss',
spriteDestImg : 'public/images/sprite/spritesheet.png',
spriteSrc : 'public/images/min/*.{png,jpg,gif}',
imageminCwd : 'public/images/',
imageminDest : 'public/images/min'
};
//grunt Watch ===============================
config.watch = {
scripts: {
files: ["<%= src.libFolder %>", "<%= src.sassFolder %>"]
,tasks: ["dev", "sass:dist"]
//,tasks: ["dev",'sass:dist']
}
}
I hope that helped you.

Answer 2

It's been quite a long while since I asked this question. I just ran into the same issue again and found the answer so here it is:
In the end it turned out to be that one of the files I was trying to analyse was causing the crash. This particular Javascript environment allows for C-like preprocessor directives and the Javascript file had something like this:
var mySettings = {
//#ifdef FOO_CONSTANT
setting : constants.FOO_SETTING
//#endif
//#ifdef BAR_CONSTANT
setting : constants.BAR_SETTING
//#endif
};
I guess the problem is that if this is read as strictly Javascript, the preprocessor directives are just plane comments, and there's a comma missing between the two properties, so Grunt complexity is unable to read this because of a syntax error. Using --force makes no difference BTW.
The annoying part is that this is all the error shows:
$ grunt --force
Running "complexity:generic" (complexity) task
Warning: undefined: Unexpected token, expected , (17570:1) Used --force, continuing.
Done, but with warnings.
So while it does say expected , (175:1) it doesn't say in which of the several Javascript files in this project the problem was found!
Just adding exclude: ['path/to/MyFileWithPreprocessorDirectives.js'] to Gruntfile.js in order to exclude this file from the analysis gets me around the problem.
