1 | # Contributing to assemble-helpers
2 |
3 | First and foremost, thank you! We appreciate that you want to contribute to assemble-helpers, your time is valuable, and your contributions mean a lot to us.
4 |
5 | **What does "contributing" mean?**
6 |
7 | Creating an issue is the simplest form of contributing to a project. But there are many ways to contribute, including the following:
8 |
9 | - Updating or correcting documentation
10 | - Feature requests
11 | - Bug reports
12 |
13 | If you'd like to learn more about contributing in general, the [Guide to Idiomatic Contributing](https://github.com/jonschlinkert/idiomatic-contributing) has a lot of useful information.
14 |
15 | **Showing support for assemble-helpers**
16 |
17 | Please keep in mind that open source software is built by people like you, who spend their free time creating things the rest the community can use.
18 |
19 | Don't have time to contribute? No worries, here are some other ways to show your support for assemble-helpers:
20 |
21 | - star the [project](https://github.com/jonschlinkert/assemble-helpers)
22 | - tweet your support for assemble-helpers
23 |
24 | ## Issues
25 |
26 | ### Before creating an issue
27 |
28 | Please try to determine if the issue is caused by an underlying library, and if so, create the issue there. Sometimes this is difficult to know. We only ask that you attempt to give a reasonable attempt to find out. Oftentimes the readme will have advice about where to go to create issues.
29 |
30 | Try to follow these guidelines
31 |
32 | - **Investigate the issue**:
33 | - **Check the readme** - oftentimes you will find notes about creating issues, and where to go depending on the type of issue.
34 | - Create the issue in the appropriate repository.
35 |
36 | ### Creating an issue
37 |
38 | Please be as descriptive as possible when creating an issue. Give us the information we need to successfully answer your question or address your issue by answering the following in your issue:
39 |
40 | - **version**: please note the version of assemble-helpers are you using
41 | - **extensions, plugins, helpers, etc** (if applicable): please list any extensions you're using
42 | - **error messages**: please paste any error messages into the issue, or a [gist](https://gist.github.com/)
43 |
44 | ## Above and beyond
45 |
46 | Here are some tips for creating idiomatic issues. Taking just a little bit extra time will make your issue easier to read, easier to resolve, more likely to be found by others who have the same or similar issue in the future.
47 |
48 | - read the [Guide to Idiomatic Contributing](https://github.com/jonschlinkert/idiomatic-contributing)
49 | - take some time to learn basic markdown. This [markdown cheatsheet](https://gist.github.com/jonschlinkert/5854601) is super helpful, as is the GitHub guide to [basic markdown](https://help.github.com/articles/markdown-basics/).
50 | - Learn about [GitHub Flavored Markdown](https://help.github.com/articles/github-flavored-markdown/). And if you want to really go above and beyond, read [mastering markdown](https://guides.github.com/features/mastering-markdown/).
51 | - use backticks to wrap code. This ensures that code will retain its format, making it much more readable to others
52 | - use syntax highlighting by adding the correct language name after the first "code fence"

2 |
3 | > Plugin that adds helpers for assemble projects. Includes both sync and async helpers that take advantage of assemble's powerful features.
4 |
5 | ## Install
6 |
7 | Install with [npm](https://www.npmjs.com/):
8 |
9 | ```sh
10 | $ npm install --save assemble-helpers
11 | ```
12 |
13 | ## Usage
14 |
15 | ```js
16 | var assembleHelpers = require('assemble-helpers');
17 | var assemble = require('assemble');
18 | var app = assemble();
19 |
20 | app.use(assembleHelpers());
21 | ```
22 |
23 | ## Helpers
24 |
25 | ### [{{content}}](index.js#L30)
26 |
27 | Returns the stringified contents from a `view` object, or just returns the value if `view` is a string.
28 |
29 | **Params**
30 |
31 | * `view` **{String|Object}**
32 | * `returns` **{String}**: Returns `view.contents` or the value if it's a string.
33 |
34 | **Example**
35 |
36 | ```js
37 | app.view('foo', {contents: 'This is contents'});
38 |
39 | // {{contents foo}}
40 | //=> "This is contents"
41 | ```
42 |
43 | ### [{{find}}](index.js#L62)
44 |
45 | Get the first view with the given `name` from any collection, or the specified `collection`. If no collection is passed only `renderable` collections will be searched ("renderable" collections are any collections not specified as `partials` and `layouts`).
46 |
47 | **Params**
48 |
49 | * `name` **{String}**: The name/key (`view.stem`, `view.basename`, `view.relative` or `view.path`) of the view to find. It's good practice to use a longer path when practical.
50 | * `collection` **{String}**: (optional)
51 | * `returns` **{Object|undefined}**: Returns the view if found, or `undefined` if not.
52 |
53 | **Example**
54 |
55 | ```handlebars
56 | {{find "foo"}}
57 | {{find "foo.hbs" }}
58 | {{find "a/b/c/foo.hbs"}}
59 |
60 |
61 | {{find "foo" "pages"}}

82 | ```
83 |
84 | ### [{{config}}](index.js#L110)
85 |
86 | Get the value of `prop` from `app.options` or the context. Dot-notation may be used. Context values from `app.cache.data` will override values from `app.options`, and values from locals will override all other values.
87 |
88 | **Params**
89 |
90 | * `prop` **{String}**
91 | * `locals` **{Object}**: (optional) Locals to merge onto the options.

98 | app.data({a: {b: 'd'}});
99 | app.data({foo: {a: {b: 'ABC'}}});
100 |
101 | // {{config "x"}} => 'z'
102 | // {{config "a.b.c"}} => 'eee'
103 | // {{config "a.b"}} => '{c: 'eee'}'
104 |
105 | // with locals
106 | // {{config foo "a.b.c"}} => 'ABC'
107 | // {{config foo "a.b"}} => '{c: 'ABC'}'
108 | ```
109 |

117 | * `returns` **{any}**
118 |
119 | **Example**
120 |
121 | ```js
122 | app.option({a: {b: 'c'}});
123 |
124 | // {{option "a"}} => '{b: 'c'}'
125 | // {{option "a.b"}} => 'c'
126 | ```
127 |
128 | ### [{{enabled}}](index.js#L168)

147 | ```
148 |
149 | ### [{{disabled}}](index.js#L193)
150 |
151 | Return the given value of `prop` from `this.options`.
152 |

155 | * `prop` **{String}**
156 | * `returns` **{any}**
157 |
158 | **Example**

160 | ```js
161 | app.option('foo', false);
162 | app.option('bar', true);

165 | // {{disabled "foo"}} => true
166 | // {{disabled "bar"}} => false
