play-sass

Sass asset handling plugin for Play 2.x. Implemented as sbt plugin.

Prerequisites

Sass compiler needs to be installed for plugin to work. This means that sass executable needs to be found in path. Sass can be installed by by installing sass gem.

gem install sass

You can verify that sass has been installed by following command:

% sass -v
Sass 3.1.16 (Brainy Betty)

Installation

Plugin versions are linked to different Play versions. Each Play-version has some differences in how plugin is enabled. Please select suitable instructions below.

After following the instructions *.sass and *.scss files in app/assets directories will then be automatically compiled to *.css files. Files starting with _-character will be left out from compilation as per Play convention.

Play 2.3

Add following to your projects project/plugins.sbt

resolvers += "Sonatype OSS Releases" at "https://oss.sonatype.org/content/repositories/releases"

addSbtPlugin("net.litola" % "play-sass" % "0.4.0")

After that you'll need to enable plugin in build.sbt.

lazy val root = (project in file(".")).enablePlugins(PlayScala, net.litola.SassPlugin)

If you would like to pass your own command line arguments to Sass call, you can do it with .settings call. For example to use Compass you should append following after previous line.

.settings(
	sassOptions := Seq("--compass")
)

Play 2.2

Add following to your projects project/plugins.sbt

resolvers += "Sonatype OSS Releases" at "https://oss.sonatype.org/content/repositories/releases"

addSbtPlugin("net.litola" % "play-sass" % "0.3.0")

In addition you'll need to add settings to your project. On Play 2.2 this is done by modifying build.sbt and appending following line:

net.litola.SassPlugin.sassSettings

If you would like to pass your own command line arguments to Sass call, you can do it by overriding SassPlugin.sassOptions. For example to use Compass you can use following:

net.litola.SassPlugin.sassSettings

net.litola.SassPlugin.sassOptions := Seq("--compass")

Play 2.0 & 2.1

Add following to your projects project/plugins.sbt:

resolvers += "Sonatype OSS Releases" at "https://oss.sonatype.org/content/repositories/releases"

addSbtPlugin("net.litola" % "play-sass" % "0.2.0")

For 2.0 use version 0.1.3.

After that you should do following changes to project/Build.scala.

import net.litola.SassPlugin

val main = PlayProject(appName, appVersion, appDependencies, mainLang = SCALA).settings( SassPlugin.sassSettings:_* )

Usage

Source Files

This plugin expects .scss your files to be located in PROJECT_ROOT/app/assets, or some sub-folder of that folder.

Linking to generated CSS

The app/assets directory is mapped to the root path in the running app, so for instance the output of this SCSS file:

app/assets/test.scss

can be accessed via this import:

<link rel="stylesheet" href="@routes.Assets.at("test.css")">
