Object #<Object> has no method 'indexOf'

[mr-moon]

Using pretty much copy/pasted grunt config:

haml:
    files: [{
        expand: true
        src: ['server/app/views/*.haml']
        dest: 'build/app/views'
        ext: '.php'
    }]

But cannot avoid getting this error.

The --force doesn't have any effect.

And here's the verbose log:

air ~/App > grunt  --force haml --verbose --debug

Command-line options: --force, --verbose, --debug=1

Make sure you have brackets after the haml: definition and commas after each item in the files directive`. Your config should look like this:

haml: {
    files: [{
        expand: true,
        src: ['server/app/views/*.haml'],
        dest: 'build/app/views',
        ext: '.php'
    }]
}

Actually, i'm using coffeescript for my gruntfile. And the block I've initially included compiles correctly with all enclosed brackets. So this is absolutely not the case.

[mr-moon]

Just made a gruntfile.js, same result.

Ah, sorry. I should have recognized that was coffeescript.

Can you try running grunt with the --stack flag? You may need to drop the --force flag in order to output the stack trace.

Thanks.

[mr-moon]

Great. Weren't aware of --stack option. Here's the output:

grunt haml --stack

That error is being thrown down in the internals of Grunt, and I'm unable to come up with something that can reproduce it.

Would it be possible for you to publish a sample test case that exhibits this issue, along with what version of grunt and node you're using?

[mr-moon]

npm 1.3.14 grunt-cli v0.1.11 grunt v0.4.2

But the test case - is actually no files at all. Tried with 1 file just 1 simple code like <strong><%= item.title %></strong>, but all was the same.

And I'm on OS X Mavericks.

Hi, try this... I had the same problem, but with this code it works ;)

'use strict';
module.exports = function(grunt) {
  grunt.initConfig({
    haml: {
      basic_html: {
        files: [{
          expand: true,
          cwd: 'src/templates',
          src: ['**/*.haml'],
          dest: 'dest/',
          ext: '.phtml'
        }],     
      },
    },
  })
    grunt.loadNpmTasks('grunt-haml-php');
};

Hey, had the same issue and your solution worked @Ceda. So basically it has to do with adding and extra level in the hierarchy. This works:

    haml: {
      compile: {
        files: [{
          expand: true,
          src: ['*.haml'],
          dest: 'dest/',
          ext: '.php'
        }],     
      },
    },

And this doesn't work (gives the error OP posted)

    haml: {
      files: [{
        expand: true,
        src: ['*.haml'],
        dest: 'dest/',
        ext: '.php'
      }]
    },
