extend error Eminence, Missouri

This is done via interpolation. As with all constructor functions, you can use the prototype of the constructor to add properties or methods to all instances created with that constructor. The order of pairs in a map is always the same as when the map was created. The only exception are units; Sass normally allows any valid identifier to be used as an identifier, but identifiers may not contain a hyphen followed by a digit.

List Operations Lists don’t support any special operations. Overrides the Object.prototype.toSource() method. Is there a role with more responsibility? For example: #admin .tabbar a { font-weight: bold; } #demo .overview .fakelink { @extend a; } While it would technically be possible to generate all selectors that could possibly match either

Define The decorator takes a name for the error type, and returns a function that takes an error message, and encloses the error name. Similar to message. So you can create custom classes from existing classes like extending the array class. up down -8 hollodotme ¶2 years ago Not mentioned in the class structure on top If a hash, :css_location is ignored and this option designates a mapping between input and output directories.

This defaults to the working directory and, in Rack, Rails, or Merb, whatever :template_location is. For example: p { color: rgba(255, 0, 0, 0.75) + rgba(0, 255, 0, 0.75); } is compiled to: p { color: rgba(255, 255, 0, 0.75); } The alpha channel of a How it Works @extend works by inserting the extending selector (e.g. .seriousError) anywhere in the stylesheet that the extended selector (.e.g .error) appears. blue, #04a3f9, rgba(255, 0, 0, 0.5)) booleans (e.g.

Thanks for the heads up! –Gautham C. throw { type: "validation", message: "Invalid timestamp" } And when you catch the error: catch(e) { if(e.type === "validation") { // handle error } // re-throw, or whatever else } share|improve

calidion commented Jul 10, 2016 Thanks for the code snippet. Defaults to Sass::Importers::Filesystem. :sourcemap Controls how sourcemaps are generated. It’s useful for validating arguments to mixins and functions. I removed it.

Is this really an issue for you? –Jonathan Benn Oct 6 '14 at 19:21 Why not just return error? –Eric Oct 7 '14 at 9:56 Yes, the require 'sass/plugin/rack' use Sass::Plugin::Rack Sass stylesheets don’t work the same as views. Raw test-error.js // Mini test suite for our custom error var assert = require('assert'); var CustomError = require('./errors/custom-error'); function doSomethingBad() { throw new CustomError('It went bad!', 42); } try { doSomethingBad(); All imported SCSS and Sass files will be merged together into a single CSS output file.

Since multiline comments become part of the resulting CSS, interpolation within them is resolved. Error types Besides the generic Error constructor, there are six other core error constructors in JavaScript. I find it helps me to track down issues -- post-mortem -- but also to clearly handle expected errors. Sass math functions preserve units during arithmetic operations.

If is a list of lists, each element of the sub-lists is assigned to the respective variable. Available options are: :style Sets the style of the CSS output. Note: Using new is optional when constructing a custom error. It will provide you an extend() method for the Error type.

The second param is what we need to hide the stack frame, given a function, all frame above it(including itself) will be omit from the stack.class MyError extends Error { constructor(message) Files using this syntax have the .scss extension. Variables begin with dollar signs, and are set like CSS properties: $width: 5em; You can then refer to them in properties: #main { width: $width; } Variables are only available within Implemented in JavaScript 1.1.

Defaults to :sass. :property_syntax Forces indented-syntax documents to use one syntax for properties. Control Directives & Expressions SassScript supports basic control directives and expressions for including styles only under some conditions or including the same style several times with variations. Not the answer you're looking for? You should also create errors in logical places.

Since the named arguments are variable names, underscores and dashes can be used interchangeably. and these methods:

* @return Exception|null
final public function getPrevious();

For example: $family: unquote("Droid+Sans"); @import url("http://fonts.googleapis.com/css?family=#{$family}"); would compile to @import url("http://fonts.googleapis.com/css?family=Droid+Sans"); Partials If you have a SCSS or Sass file that you want to import but don’t want to compile to syntax extend() takes two arguments : subTypeName & errorCode [optional] it returns the newly created error type more examples for a web app something useful var AppError = Error.extend('AppError', 500);var ClientError = Error.extend('ClientError', 400); extend ClientError further for specific See Output Style. :syntax The syntax of the input file, :sass for the indented syntax and :scss for the CSS-extension syntax. Node developers usually avoid raising exceptions, but if you really think it's necessary you can use throw new Error('I am Error') and then assert.throws in your tests.

For example, if you write a.important {@extend .notice}, it’s an error if there are no selectors that contain .notice. Nested Properties CSS has quite a few properties that are in “namespaces;” for instance, font-family, font-size, and font-weight are all in the font namespace. Some people find this to be easier to read and quicker to write than SCSS. Conclusion I create a lot of Error classes in my projects, but I rarely use throw and catch.
