grunt-regex-check

Grunt plugin to detect illegal expressions in javascript code with regular expressions

Getting Started

This plugin requires Grunt ~0.4.1

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-regex-check --save-dev

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

grunt.loadNpmTasks('grunt-regex-check');

The ""regex-check"" task

Overview

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

Options

options.excluded

Type: String Default value: none Mandatory: No

A string value that is used to do something with whatever.

options.pattern

Type: Regular expression Default value: none Mandatory: Yes

A string value that is used to do something else with whatever else.

options.breakOnError

Type: boolean Default value: true Mandatory: false

By setting to false you can only warn the user, but not break the build.

Usage Examples

Options

Note that there are no default options and you must specify the configuration values

In this example, the configuration is looking through all javascript files in 'src', except for those excluded ones and will fail the build if the string 'console' is found

Example: Check all source files to ensure they do not contain console. Exclude those that have excluded in the file name

grunt.initConfig({
  "regex-check": {
    files: "src/**/*.js",
    options: {
      excluded : "src/**/*xcluded.js",
      pattern : /console/g
    },
  },
})

Example: Find console calls, but only warn the user without stopping the grunt build

grunt.initConfig({
  "regex-check": {
    files: "src/**/*.js",
    options: {
      excluded : "src/**/*xcluded.js",
      pattern : /console/g,
      breakOnError: false
    },
  },
})

Example: Check all files in src/server and src/logger to ensure they do not contain throw or catch. Exclude three specific files

grunt.initConfig({
  "regex-check": {
    files: ["src/server/**/*.js", "src/logger/**/*.js"],
    options: {
      excluded : ["src/server/ajax/requestErrors.js", "src/logger/defaultErrorLogger.js", "src/server/jqueryPluginWrapper.js"],
      pattern : /(throw)|(catch)/g
    },
  },
})

grunt.initConfig({
  "regex-check": {
        directives: {
            files: [
                {src: ['app/js/**/*-drtv.js']}
            ],
            options: {
                // force file naming conventions
                pattern: /templateUrl(?!(.*-tmpl.html|.*\{|;))/g
            }
        },
        scopes: {
            files: [
                {src: ['app/js/**/*.js']}
            ],
            // Check that scopes that are created programatically with $new are eventually cleaned up
            options: {
                pattern: /\$new(?!(\$on('\$destroy')))/g
            }
        }
  },
})
