Install

Install with npm:

$ npm i generator-util --save

Usage

var util = require('generator-util');

API

.exists

Return true if a filepath exists on the file system.

Params

• filepath {String}
• returns {Boolean}

Example

utils.exists('foo');
//=> false

utils.exists('gulpfile.js');
//=> true

.renameKey

Rename the key used for storing views/templates

Params

• key {String}
• view {Object}: the renameKey method is used by [templates][] for both setting and getting templates. When setting, view is exposed as the second parameter.
• returns {String}

.toAlias

Opposite of .toFullname, creates an "alias" from the given name by either stripping options.prefix from the name, or just removing everything up to the first dash. If options.alias is a function, it will be used instead.

Params

• name {String}
• options {Object}
• returns {String}

Example

utils.toAlias('generate-foo');
//=> 'foo';

utils.toAlias('a-b-c', {prefix: 'a-b'});
//=> 'c';

.toFullname

Opposite of .toAlias, creates a generator name from the given alias and namespace.

Params

• alias {String}
• namespace {String}
• returns {String}

Example

utils.toFullname('foo', 'generate');
//=> 'generate-foo';

utils.toFullname('generate-bar', 'generate');
//=> 'generate-bar'

.toGeneratorPath

Create an object-path for looking up a generator.

Params

• name {String}
• returns {String}

Example

utils.toGeneratorPath('a.b.c');
//=> 'generators.a.generators.b.generators.c'

.getGenerator

Get a generator from app.

Params

• app {Object}
• name {String}: Generator name
• returns {Object}: Returns the generator instance.

.tryResolve

Try to require.resolve module name, first locally then in the globaly npm directory. Fails silently if not found.

Params

• name {String}: The name or filepath of the module to resolve
• options {Object}: Pass options.cwd and/or options.configfile (filename) to modify the path used by resolve.
• returns {String|undefined}

Example

utils.tryResolve('foo');
// or
utils.tryResolve('generate-foo');
// or
utils.tryResolve('generate-foo', {cwd: require('global-modules')});
// or
utils.tryResolve('./foo/bar/baz.js');

.tryRequire

Try to require the given module, failing silently if it doesn't exist. The function first calls require on the given name, then tries require(path.resolve(name)) before giving up.

Params

• name {String}: The module name or file path
• returns {any|undefined}: Returns the value of requiring the specified module, or undefined if unsuccessful.

Example

utils.tryRequire('foo');

.tableize

Modified from the tableize lib, which replaces dashes with underscores, and we don't want that behavior. Tableize obj by flattening and normalizing the keys.

Params

• {Object}: obj
• returns {Object}

.isFunction

Returns true if the given value is a function.

Params

• value {any}
• returns {Boolean}

Example

utils.isFunction('foo');
//=> false

utils.isFunction(function() {});
//=> true

.isBoolean

Returns true if the given value is a boolean.

Params

• value {any}
• returns {Boolean}

Example

utils.isBoolean('foo');
//=> false

utils.isBoolean(false);
//=> true

.isString

Returns true if a the given value is a string.

Params

• value {any}
• returns {Boolean}

Example

utils.isString('foo');
//=> false

utils.isString({});
//=> true

.isObject

Returns true if a the given value is an object.

Params

• value {any}
• returns {Boolean}

Example

utils.isObject('foo');
//=> false

utils.isObject({});
//=> true

.arrayify

Cast the given value to an array.

Params

• value {String|Array}
• returns {Array}

Example

utils.arrayify('foo');
//=> ['foo']

utils.arrayify(['foo']);
//=> ['foo']
