{{less}} 
{{less}} handlebars helper. This helper allows you to use LESS inside style tags in your HTML. By default, the resulting CSS will be rendered inside the
<style>...</style>tags of the rendered HTML, but you may alternatively define a destination path using thedesthash option of the helper.
Quickstart
In the root of your project, run the following in the command line:
npm i handlebars-helper-less --save-devExample:
{{#less}}<style>@foo-border-color: #eee; // Foo.foo { margin: 20px 0; padding: 20px; border-left: 3px solid @foo-border-color;}</style>{{/less}}Compiles to:
Options
In addition to native Less.js options, the following helper options may be defined on the less object in the assemble options, e.g:
assemble: options: less: // less options here dest
Type: String
Default: undefined
Optionally define a destination path for the compiled CSS. The filename will be appended to either a destdir defined in the less options, or to the assets path, if defined. When no dest is defined in the hash, the resulting CSS will be rendered inside <style>...</style> tags in the output HTML.
For example, give the following expression: {{#less dest="foo.css"}}...{{/less}}, and the following defined in the Gruntfile:
assemble: options: assets: 'dist/assets/css' The compiled CSS will be saved to: dist/assets/css/foo.css.
destdir
Type: String
Default: undefined
Optionally define a destination directory to prepend to any dest used in the options hash of the helper.
For example, give the following expression: {{#less dest="foo.css"}}...{{/less}}, and the following defined in the Gruntfile:
assemble: options: assets: 'dist/assets/css' less: destdir: 'css' The compiled CSS will be saved to: css/foo.css.
Usage Examples
Using the dest option
HTML and LESS
Given that we have component.hbs:
Document {{#less dest="component.css"}} {{/less}} <!-- The component --> This is an awesome component! And we have this config in the Gruntfile:
assemble: options: assets: 'dist/assets/css' Rendered HTML and CSS
It would render to: dist/component.html
Document <!-- The component --> This is an awesome component! and dist/assets/css/component.css
Register the Helper
If you use Assemble choose one of the following approaches to register the helper:
Option #1: Gruntfile
Define paths to any helpers in the helpers option of your project's Gruntfile:
grunt;Option #2: Add to devDependencies and keywords
Or, add the helper to the devDependencies of your project's package.json, and then add the name of the module, handlebars-helper-less, to the keywords:
Assemble will automatically register any helpers found when matching names are defined in both keywords and devDependencies. It just works.
