I can't figure out how to get multiples less files with grunt :
less: {
dist: {
files: {
'<%= yeoman.app %>/styles/main.css': ['<%= yeoman.app %>/styles/main.less']
},
options: {
sourceMap: true,
sourceMapFilename: '<%= yeoman.app %>/styles/main.css.map',
sourceMapBasepath: '<%= yeoman.app %>/',
sourceMapRootpath: '/'
}
}
},
You have to use the expanded file syntax of grunt (http://gruntjs.com/configuring-tasks#building-the-files-object-dynamically). For exampe, to compile all lib/less/.less to build/css/.css:
less: {
dist: {
files: [{
expand: true,
cwd: 'lib/less',
src: ['*.less'],
dest: 'build/css',
ext: '.css'
}]
}
},
Up until recently I've been using a similar gruntfile to this with success. However in my latest project grunt watch is looping continually - sometimes 4 times, sometimes 15 times or so before stopping - I can't figure out how to change the gruntfile to get it working properly again.
module.exports = function (grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
// Define our source and build folders
js_path: 'public_html/js',
img_path: 'public_html/img',

"grunt-postcss": "~0.6.0",
"csswring": "~4.0.0",
"autoprefixer-core": "~6.0.1",

your issue is that concat generates its file into your js_path directory, and watch monitors all js files in that directory. So what happens is:
you modify a js source file
watch detects your modification and launches concat
concat generates output.js
watch detects output.js and launches concat
3 then 4 repeat - until you're saved by watch buffering (which prevents triggering too quickly in sequence)
To solve it, you have to remove the concat output from the watchlist.
What I recommend is to have concat output to a build directory outside your sources - it's best practice to separate build artefacts from source elements anyway. Define a build_path config variable and use it in your concat target.
If you really can't do that for a good reason, manually remove output.js from the watch with a negative directive (http://gruntjs.com/configuring-tasks#globbing-patterns):
watch: {
scripts: {
files: ['<%= js_path %>/*.js', '!<%= js_path %>/output.js'],
tasks: ['build']
},
}
Moving the postcss to a separate task has solved the problem for me.
Here are the changes to the gruntfile:
watch: {
options: {nospawn: true},
scripts: {
files: ['<%= js_path %>/*.js'],
tasks: ['build_js']
},
css: {
files: ['<%= css_path %>/*.css'],
tasks: ['build:css']
},
grunt: {
files: ['Gruntfile.js']
}
and
grunt.registerTask('build_js', ['jshint', 'concat', 'uglify']);
grunt.registerTask('build_css', ['postcss:dist']);
Using 'yo angular' I created AngularJS seed application.
Trying to run the application using 'grunt serve' is giving this error:-

Why it is looking for bower.json inside app folder? It is present one level up.
How can I fix this?

I had the same problem try commenting the line 166 in your Gruntfile.js :
I did it and it should look like this :
// Automatically inject Bower components into the app
wiredep: {
options: {
//cwd: '<%= yeoman.app %>'
},
Then run again your server with :
grunt serve
You are using an out of date version of the generator. You should update it before using it: npm update -g generator-angular. The newest version has a fix for this.
Try to downgrade grunt-wiredep to 1.8.0 as it says here
I had this same problem.
First I commented out line 166, but that didn't fix the problem.
The following plus the commenting out of line 166 did the trick:
Re-install wiredep
$ npm install --save-dev grunt-wiredep
Install dependencies
$ bower install jquery --save
Run wiredep
$ grunt wiredep
Then run your app
$ grunt serve
I am using grunt-rev with grunt-usemin for cache busting. The issue is that grunt rev modify the name of my pictures : logo.png to 45475_logo.png but there is only the root files (/index.php header.php footer.php) who are modify for get the new url. All my other php files link the wrong img.

// Load the plugin that provides the tasks.
grunt.loadNpmTasks('grunt-lib-contrib');

// Task(s).
grunt.registerTask('les', ['less']);
grunt.registerTask('proless', ['less:production']);
grunt.registerTask('devless', ['less:devevelopment']);
};
Running each of the following:
grunt les
grunt proless
grunt devless
Results in:
Warning: Object true has no method 'indexOf' Use --force to continue
If I remove the task development:{ ... } and production: { .... } and leave the interior and just change my les call to hit less it works fine.
I ran into a similar problem with contrib-concat. I think it's a syntax error on both our parts.
Try adding an array literal around your development target's "files" property, like so:
files: [{
//'<%= less_build_path %>/app.css':'<%= concat.less.dest %>',
//Dynamic expansion 1:1
expand: true,
cwd: '<%= less_src_path %>',
dest: '<%= less_build_path %>',
src: '*.less',
ext: '.less.css'
}]

Hope that helps!
