## grunt-prompt NPM version Build Status Built with Grunt > Interactive prompt for your Grunt config using console checkboxes, text input with filtering, password fields. grunt-prompt | grunt-prompt in action | |:-------------:| | grunt-prompt in action | ### Getting Started This plugin recommends Grunt 0.4.1 or newer. ### Installing bash npm install grunt-prompt --save-dev Once that's done, add this line to your project's Gruntfile.js: js grunt.loadNpmTasks('grunt-prompt'); Grunt-prompt's UI is powered by the amazing Inquirer, a project created by Simon Boudrias. | grunt-prompt in action | |:-------------:| | grunt-prompt in action | ### Overview In your project's Gruntfile, add a section named prompt to the data object passed into grunt.initConfig(). grunt-prompt is a multi-task. This means you can create multiple prompts. js grunt.initConfig({ prompt: { target: { options: { questions: [ { config: '', // arbitray name or config for any other grunt task type: '<question type>', // list, checkbox, confirm, input, password message: 'String|function()', // Question to ask the user, function needs to return a string, default: 'value', // default value if nothing is entered choices: 'Array|function(answers)', validate: function(value), // return true if valid, error message if invalid filter: function(value), // modify the answer when: function(answers) // only ask this question when this function returns true } ] } }, }, }) #### Options ##### config Type: String required This is used for three things: It will set or overwrite the config of other Grunt tasks: config: 'jshint.allFiles.reporter' The key in the resulting answers object: if (answers['jshint.allFiles.reporter'] === 'custom') {... It can be an abitrary value read using grunt.config: grunt.config('jshint.allFiles.reporter') ##### type Type: String required Type of question to ask: list: use arrow keys to pick one choice. Returns a string. checkbox: use arrow keys and space bar to pick multiple items. Returns an array. confirm: Yes/no. Returns a boolean. input: Free text input. Returns a string. password: Masked input. Returns a string. Here's an example of each type: | grunt-prompt example | |:-------------:| | grunt-prompt example | The documentation for Inquiry has more details about type as well as additional typess. ##### message Type: String|function() required Question to ask the user. If it's a function, it needs to return a string. Hint: keep it short, users hate to read. ##### default Type: String/Array/Boolean/'function' optional Default value used when the user just hits Enter. If a value field is not provided, the filter value must match the name exactly. ##### choices For question types 'list' and 'checkbox': Type: array of hashes name The label that is displayed in the UI. value optional Value returned. When not used the name is used instead. checked optional Choose the option by default. Only for checkbox. choices: [ { name: 'jshint', checked: true }, { name: 'jslint' }, { name: 'eslint' }, '---', // puts in a non-selectable separator { name: 'I like to live dangerously', value: 'none' } ] ##### validate Type: function(value) optional Return true if it is valid (true true, not a truthy value). Return string message if it is not valid. ##### filter Type: function(value) optional Use a modified version of the input for the answer. Useful for stripping extra characters, converting strings to integers. ##### when Type: function(answers) optional Choose when this question is asked. Perfect for asking questions based on the results of previous questions. ##### then Type: function(results) optional Runs after all questions have been asked. ### How to use the results in your Gruntfile You can also modify how tasks will work by changing options for other tasks. You do not need to write code to do this, it's all in the config var. Here we will let the user choose what Mocha reporter to use. js config: prompt: { mochacli: { options: { questions: [ { config: 'mochacli.options.reporter' type: 'list' message: 'Which Mocha reporter would you like to use?', default: 'spec' choices: ['dot', 'spec', 'nyan', 'TAP', 'landing', 'list', 'progress', 'json', 'JSONconv', 'HTMLconv', 'min', 'doc'] } ] } } } and create a shortcut: grunt.registerTask('test', [ 'prompt:mochacli', 'mochacli' ]); And run it: $ grunt test | grunt-prompt setting up Mocha | |:-------------:| | grunt-prompt setting up Mocha | ### How can values be accessed from my own code? This config value is accessible to all other grunt tasks via grunt.config('<config name>'). If you had this: js config: 'validation' Then later on in your custom task can access it like this: js var validation = grunt.config('validation'); ### Usage Examples | grunt-prompt with grunt-bump | |:-------------:| | grunt-prompt with grunt-bump | This is an example of how grunt-prompt for something like grunt-bump which makes it easy to update your project's version in the package.json, bower.json, and git tag. js prompt: { bump: { options: { questions: [ { config: 'bump.increment', type: 'list', message: 'Bump version from ' + '<%= pkg.version %>'.cyan + ' to:', choices: [ { value: 'build', name: 'Build: '.yellow + (currentVersion + '-?').yellow + ' Unstable, betas, and release candidates.' }, { value: 'patch', name: 'Patch: '.yellow +, 'patch').yellow + ' Backwards-compatible bug fixes.' }, { value: 'minor', name: 'Minor: '.yellow +, 'minor').yellow + ' Add functionality in a backwards-compatible manner.' }, { value: 'major', name: 'Major: '.yellow +, 'major').yellow + ' Incompatible API changes.' }, { value: 'custom', name: 'Custom: ?.?.?'.yellow + ' Specify version...' } ] }, { config: 'bump.version', type: 'input', message: 'What specific version would you like', when: function (answers) { return answers['bump.increment'] === 'custom'; }, validate: function (value) { var valid = semver.valid(value) && true; return valid || 'Must be a valid semver, such as 1.2.3-rc1. See ' + ''.blue.underline + ' for more details.'; } }, { config: 'bump.files', type: 'checkbox', message: 'What should get the new version:', choices: [ { value: 'package', name: 'package.json' + (!grunt.file.isFile('package.json') ? ' file not found, will create one'.grey : ''), checked: grunt.file.isFile('package.json') }, { value: 'bower', name: 'bower.json' + (!grunt.file.isFile('bower.json') ? ' file not found, will create one'.grey : ''), checked: grunt.file.isFile('bower.json') }, { value: 'git', name: 'git tag', checked: grunt.file.isDir('.git') } ] } ] } } } ### Release History 1.1.0 - 4 Mar 2014 - Messages can be functions instead of strings for dynamic questions. 1.0.0 - 4 Feb 2014 - Dropping support for Node 0.8. 0.2.2 - 4 Feb 2014 - Updated readme to make it auto-generated. 0.2.1 - 4 Feb 2014 - Fix bug when using a function to provide choices. 0.2.0 - 26 Jan 2014 - Added then option which runs after questions.
