-# Contributing to Gulp Sass
-
-Gulp Sass is a very light-weight [Gulp](https://github.com/gulpjs/gulp) wrapper for [`node-sass`](https://github.com/sass/node-sass), which in turn is a Node binding for [`libsass`](https://github.com/sass/libsass), which in turn is a port of [`Sass`](https://github.com/sass/sass).
-
-## Submitting Issues
-
-* Before creating a new issue, perform a [cursory search](https://github.com/issues?utf8=%E2%9C%93&q=repo%3Adlmanning%2Fgulp-sass+repo%3Asass%2Fnode-sass+repo%3Asass%2Flibsass+repo%3Asass%2Fsass+repo%3Asass-eyeglass%2Feyeglass) in the Gulp Sass, Node Sass, Libsass, and main Sass repos to see if a similar issue has already been submitted. Please also refer to our [Common Issues and Their Fixes](https://github.com/dlmanning/gulp-sass/wiki/Common-Issues-and-Their-Fixes) page for some basic troubleshooting.
-* You can create an issue [here](https://github.com/dlmanning/gulp-sass/issues). Please include as many details as possible in your report.
-* Issue titles should be descriptive, explaining at the high level what it is about.
-* Please include the version of `gulp-sass`, Node, and NPM you are using, as well as what operating system you are having a problem on.
-* _Do not open a [pull request](#pull-requests) to resolve an issue without first receiving feedback from a `collaborator` or `owner` and having them agree on a solution forward_.
-* Include screenshots and animated GIFs whenever possible; they are immensely helpful.
-* Issues that have a number of sub-items that need to be complete should use [task lists](https://github.com/blog/1375%0A-task-lists-in-gfm-issues-pulls-comments) to track the sub-items in the main issue comment.
-
-
-## Pull Requests
-
-* **DO NOT ISSUE A PULL REQUEST WITHOUT FIRST [SUBMITTING AN ISSUE](#submitting-issues)**
-* Pull requests should reference their related issues. If the pull request closes an issue, [please reference its closing in your commit messages](https://help.github.com/articles/closing-issues-via-commit-messages/). Pull requests not referencing any issues will be closed.
-* Pull request titles should be descriptive, explaining at the high level what it is doing, and should be written in the same style as [Git commit messages](#git-commit-messages).
-* Update the `CHANGELOG` with the changes made by your pull request, making sure to use the proper [Emoji](#emoji-cheatsheet).
-* Follow our JavaScript styleguides. Tests will fail if you do not.
-* Ensure that you have [EditorConfig](http://editorconfig.org/) installed in your editor of choice and that it is functioning properly.
-* Do not squash or rebase your commits when submitting a Pull Request. It makes it much harder to follow your work and make incremental changes.
-* Update the [CHANGELOG](#maintaining-thechangelog) with your changes.
-* Branches should be made off of the most current `master` branch from `git@github.com:dlmanning/gulp-sass.git`
-* Pull requests should be made into our [master](https://github.com/dlmanning/gulp-sass/tree/master) branch.
-
-### Git Commit Messages
-
-* Use the present tense (`"Add feature"` not `"Added Feature"`)
-* Use the imperative mood (`"Move cursor to…"` not `"Moves cursor to…"`)
-* Limit the first line to 72 characters or less
-* Consider including relevant Emoji from our [Emoji cheatsheet](#emoji-cheatsheet)
-
-## Creating a New Version
-
-Versioning is done through [SEMVER](http://semver.org/). When creating a new version, create new release branch off of `master` with the version's name, and create a new tag with `v` prefixed with the version's name from that branch. 
-
-For instance, if you are creating version `1.1.0`, you would create a branch `release/1.1.0` from `master` and create a tag `v1.1.0` from branch `release/1.1.0`.
-
-### Maintaining the Changelog
-
-The Changelog should have a list of changes made for each version. They should be organized so additions come first, changes come second, and deletions come third. Version numbers should be 2nd level headers with the `v` in front (like a tag) and the date of the version's most recent update should be underneath in italics.
-
-Changelog messages do not need to cover each individual commit made, but rather should have individual summaries of the changes made. Changelog messages should be written in the same style as [Git commit messages](#git-commit-messages).
-
-## Emoji Cheatsheet
-
-When creating creating commits or updating the CHANGELOG, please **start** the commit message or update with one of the following applicable Emoji. Emoji should not be used at the start of issue or pull request titles.
-
-* :art: `:art:` when improving the format/structure of the code
-* :racehorse: `:racehorse:` when improving performance
-* :memo: `:memo:` when writing long-form text (documentation, guidelines, principles, etc…)
-* :bug: `:bug:` when fixing a bug
-* :fire: `:fire:` when removing code or files
-* :green_heart: `:green_heart:` when fixing the CI build
-* :white_check_mark: `:white_check_mark:` when adding tests
-* :lock: `:lock:` when dealing with security
-* :arrow_up: `:arrow_up:` when upgrading dependencies
-* :arrow_down: `:arrow_down:` when downgrading dependencies
-* :shirt: `:shirt:` when removing linter warnings
-* :shipit: `:shipit:` when creating a new release

+subject to the following conditions:

-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
+The above copyright notice and this permission notice shall be included in all
+copies or substantial portions of the Software.

-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-# gulp-sass
+[![Build Status](https://travis-ci.org/dlmanning/gulp-sass.svg?branch=master)](https://travis-ci.org/dlmanning/gulp-sass)

-Sass plugin for [Gulp](https://github.com/gulpjs/gulp).
+gulp-sass
+=========

-This is a fork of [David Manning's Gulp Sass](https://github.com/dlmanning/gulp-sass).
+SASS plugin for [gulp](https://github.com/gulpjs/gulp).

-# Support
-
-Only [Active LTS and Current releases][1] are supported.
-
-[1]: https://github.com/nodejs/Release#release-schedule
-
-# Install
+#Install

 ```
-yarn add --dev sass @selfisekai/gulp-sass
+npm install gulp-sass
 ```

-# Basic Usage
+#Basic Usage

-Something like this will compile your Sass files:
+Something like this:

 ```javascript
-'use strict';
+var gulp = require('gulp');
+var sass = require('gulp-sass')

-const gulp = require('gulp');
-const sass = require('@selfisekai/gulp-sass');
-
-sass.compiler = require('sass');
-
-gulp.task('sass', () => {
-  return gulp.src('./sass/**/*.scss')
-    .pipe(sass().on('error', sass.logError))
-    .pipe(gulp.dest('./css'));
-});
-
-gulp.task('sass:watch', () => {
-  gulp.watch('./sass/**/*.scss', ['sass']);
+gulp.task('sass', function () {
+	gulp.src('./scss/*.scss')
+		.pipe(sass())
+		.pipe(gulp.dest('./css'));
 });
 ```

-You can also compile synchronously, doing something like this:
+Options passed as a hash into `sass()` will be passed along to [`node-sass`](https://github.com/sass/node-sass)

-```javascript
-'use strict';
+## gulp-sass specific options

-const gulp = require('gulp');
-const sass = require('@selfisekai/gulp-sass');
+#### `errLogToConsole: true`

-sass.compiler = require('sass');
+If you pass `errLogToConsole: true` into the options hash, sass errors will be logged to the console instead of generating a `gutil.PluginError` object. Use this option with `gulp.watch` to keep gulp from stopping every time you mess up your sass.

-gulp.task('sass', () => {
-  return gulp.src('./sass/**/*.scss')
-    .pipe(sass.sync().on('error', sass.logError))
-    .pipe(gulp.dest('./css'));
-});
+#### `onSuccess: callback`

-gulp.task('sass:watch', () => {
-  gulp.watch('./sass/**/*.scss', ['sass']);
-});
-```
+Pass in your own callback to be called upon successful compilaton by node-sass. The callback has the form `callback(css)`, and is passed the compiled css as a string. Note: This *does not* prevent gulp-sass's default behavior of writing the output css file.

-You can choose whether to use [Dart Sass][] or [Node Sass][] by setting the `sass.compiler` property. Dart Sass will be used by default, but it's strongly recommended that you set it explicitly for forwards-compatibility in case the default ever changes.
+#### `onError: callback`

-Compiler    | Maintained | No installation problems
------------|------------|-------------------------
-[Dart Sass] | yes        | yes
-[Node Sass] | no         | no
-
-[Dart Sass]: http://sass-lang.com/dart-sass
-[Node Sass]: https://github.com/sass/node-sass
-
-Note that when using Dart Sass, **synchronous compilation is twice as fast as asynchronous compilation** by default, due to the overhead of asynchronous callbacks.
-
-## Options
-
-Pass in options just like you would for [Node Sass](https://github.com/sass/node-sass#options); they will be passed along just as if you were using Node Sass. Except for the `data` option which is used by gulp-sass internally. Using the `file` option is also unsupported and results in undefined behaviour that may change without notice.
-
-For example:
-
-```javascript
-gulp.task('sass', () => {
- return gulp.src('./sass/**/*.scss')
-   .pipe(sass({outputStyle: 'compressed'}).on('error', sass.logError))
-   .pipe(gulp.dest('./css'));
-});
-```
-
-Or this for synchronous code:
-
-```javascript
-gulp.task('sass', () => {
- return gulp.src('./sass/**/*.scss')
-   .pipe(sass.sync({outputStyle: 'compressed'}).on('error', sass.logError))
-   .pipe(gulp.dest('./css'));
-});
-```
+Pass in your own callback to be called upon a sass error from node-sass. The callback has the form `callback(err)`, where err is the error string generated by libsass. Note: this *does* prevent an actual `gulpPluginError` object from being created.

 ## Source Maps

-`gulp-sass` can be used in tandem with [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps) to generate source maps for the Sass to CSS compilation. You will need to initialize [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps) prior to running `gulp-sass` and write the source maps after.

+  .pipe(sourcemaps.init());
+    .pipe(sass())
  .pipe(sourcemaps.write())
-  .pipe(gulp.dest('./css'));
-});
+  .pipe('./css');
+
+// will write the source maps inline in the compiled CSS files
 ```

-By default, [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps) writes the source maps inline in the compiled CSS files. To write them to a separate file, specify a path relative to the `gulp.dest()` destination in the `sourcemaps.write()` function.

-# Issues
+#Imports and Partials

-`gulp-sass` is a very light-weight wrapper around either [Dart Sass][] or [Node Sass][] (which in turn is a Node binding for [LibSass][]). Because of this, the issue you're having likely isn't a `gulp-sass` issue, but an issue with one those projects or with [Sass][] as a whole.
+gulp-sass now automatically passes along the directory of every scss file it parses as an include path for node-sass. This means that as long as you specify your includes relative to path of your scss file, everything will just work.

-[LibSass]: https://sass-lang.com/libsass
-[Sass]: https://sass-lang.com
+scss/includes/_settings.scss:

-If you have a feature request/question how Sass works/concerns on how your Sass gets compiled/errors in your compiling, it's likely a Dart Sass or LibSass issue and you should file your issue with one of those projects.
+```scss
+$blue: #3bbfce;
+$margin: 16px;
+```

-If you're having problems with the options you're passing in, it's likely a Dart Sass or Node Sass issue and you should file your issue with one of those projects.
+scss/style.scss:
+
+```scss
+@import "includes/settings";
+
+.content-navigation {
+  border-color: $blue;
+  color:
+    darken($blue, 9%);
+}
+
+.border {
+  padding: $margin / 2;
+  margin: $margin / 2;
+  border-color: $blue;
+}
+```

-We may, in the course of resolving issues, direct you to one of these other projects. If we do so, please follow up by searching that project's issue queue (both open and closed) for your problem and, if it doesn't exist, filing an issue with them.
