# metalsmith-register-helpers
|
|||
|
|
|
|||
|
|
A Metalsmith plugin for registering Handlebars helpers.
|
|||
|
|
|
|||
|
|
## CLI Usage
|
|||
|
|
|
|||
|
|
Install via npm and then add the `metalsmith-register-partials` key to your `metalsmith.json` plugins, like so:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
{
|
|||
|
|
"plugins": {
|
|||
|
|
"metalsmith-register-helpers": {
|
|||
|
|
"directory": "path/to/helpers"
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
This will register all helpers in the specified directory, and use the first part of the filename as the helper name. As a simple (and admittedly contrived) example, you could add a helper that wraps everything in `<strong>` tags, stored in the file `strong.js`:
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
module.exports = function (content) {
|
|||
|
|
return '<strong>' + content + '</strong>'
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
And then access it in your templates:
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<pre><code>{{ strong myJSONMetadata }}</code></pre>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Adding Handlebars Helpers
|
|||
|
|
|
|||
|
|
There are lots of helpers you could try this with in the [Handlebars Helpers](https://github.com/assemble/handlebars-helpers) library. For example, add the `capitalizeFirst` helper into `helpers/ellipsis.js`:
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
/**
|
|||
|
|
* capitalizeFirst.js
|
|||
|
|
* http://git.io/vUJU2
|
|||
|
|
*/
|
|||
|
|
|
|||
|
|
module.exports = function (str) {
|
|||
|
|
if (str && typeof str === "string") {
|
|||
|
|
return str.charAt(0).toUpperCase() + str.slice(1)
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Now, you can access it in your templates:
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<h1>{{ capitalizeFirst "the lost typo devision." }}</h1>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Adding `devDependencies` as helpers
|
|||
|
|
|
|||
|
|
If you’d prefer, this is another way to include helpers installed as `dependencies` in your `package.json` file into your Metalsmith project. For example, you can install the [Moment Handlebars helper](https://www.npmjs.com/package/helper-moment):
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
npm install --save helper-moment
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Then, add it as a helper in `_helpers/moment.js`:
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
var helperMoment = require('helper-moment');
|
|||
|
|
|
|||
|
|
module.exports = function (str, pattern){
|
|||
|
|
return helperMoment(str, pattern)
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
You can now access it in your template:
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<time date-time="{{ date }}">{{ moment date format="MMMM Do, YYYY"}}</time>
|
|||
|
|
```
