grunt-todos

Grunt plugin for finding todos/fixmes in code

Getting Started

This plugin requires Grunt ~0.4.0

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-todos --save-dev

One the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-todos');

The "todos" task

Overview

In your project's Gruntfile, add a section named todos to the data object passed into grunt.initConfig().

grunt.initConfig({
  todos: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
})

Options

options.priorities

Type: Object Default value: { low : /TODO/, med : /FIXME/, high : null }

An object that specifies what the various priorities are for the target. High will add to the errorCount.

options.verbose

Type: Boolean Default value: true

Verbose mode will cause the plugin to report on every file, regardless if there are actual lines to report or not. If set to false, only files with todos will be mentioned.

options.reporter

Type: String|Object Default value: 'default'

Specify a reporter to use. A string value will be resolved first to one of the bundled reporter, otherwise passedto require().

Bundled reporters:

• default - classic console reporter.
• markdown - simple markdown format.
• path - console reporter that print full file-paths.

See below for the 'Custom reporter' section on how to create a custom reporter.

Usage Examples

Default Options

In this example, the default options are used to find all the TODOs and FIXMEs in the code.

grunt.initConfig({
  todos: {
    options: {},
    src : ['src/testing', 'src/123']
  }
})

Save to file

Use the grunt file src/dest convention to write reporter output to a file.

grunt.initConfig({
  todos: {
    options: {},
    files: {
      'path/files.txt': ['src/testing', 'src/123']
    }
  }
})

Custom Options

In this example, custom options are used to escalate TODO to med priority.

grunt.initConfig({
  todos: {
    options: {
        priorities : {
            low : null,
            med : /(TODO|FIXME)/
        }
    },
    src : ['src/testing', 'src/123']
  }
})

In this example, we want minimize the total output by setting verbose to false.

grunt.initConfig({
  todos: {
    options: {
        verbose: false
    },
    src : ['src/**/*.js']
  }
})

Custom Reporters

A custom reporter can be used to change the output of the task.

Reporters have three functions, header, fileTasks, and footer, that should return strings. The result of header is printed once at the beginning of the task. The result of footer is printed once at the end of the task. The fileTasks function is called once for each file that is being scanned.

Printing to the console or to a file is still controlled by the use of the src versus files options.

grunt.initConfig({
  todos: {
    options: {
      reporter: {
        header: function () {
          return '-- Begin Task List --\n';
        },
        fileTasks: function (file, tasks, options) {
          var result = '';
          result += 'For ' + file + '\n';
          tasks.forEach(function (task) {
            result += '[' + task.lineNumber + ' - ' + task.priority + '] ' + task.line + '\n';
          });
          result += '\n';
          return result;
        },
        footer: function () {
          return '-- End Task List--\n';
        }
      }
    }
  }
})

file Parameter

Type: String The path to the file being scanned for tasks.

tasks Parameter

Type: Array Contains the list of tasks found in the file.

An example tasks looks like this:

{
  file: 'path/to/file.js',
  lineNumber: 27,
  priority: 'low', // 'med' or 'high'
  line: '    // TODO something grand and spectacular',
  pattern: /\bTODO\b/ // Pattern used to recognize the priority
}

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
