sbt-web plugin for concatenating files together, using the sbt-web asset pipeline.
Add the plugin to your project/plugins.sbt
:
addSbtPlugin("net.ground5hark.sbt" % "sbt-concat" % "0.1.9")
Add the Sonatype releases resolver:
resolvers += Resolver.sonatypeRepo("releases")
Enable the sbt-web plugin for your project:
lazy val root = (project in file(".")).enablePlugins(SbtWeb)
Add the concat
task to your asset pipeline in your build.sbt
:
pipelineStages := Seq(concat)
Below is an example of specifying concat groups within your build.sbt
file. You can use PathFinder
objects or a
Seq[String]
to specify the files to concatenate together.
Concat.groups := Seq(
"style-group.css" -> group(Seq("css/style1.css", "css/style2.css")),
"script-group.js" -> group(Seq("js/script1.js", "js/script2.js")),
"style-group2.css" -> group((sourceDirectory.value / "assets" / "style") * "*.css")
)
Note that with a PathFinder
, you will need to take care to ensure that the files it selects will be concatenated in
the order that you desire.
To match entries in Seq[String]
in group PathMapping
is used. Only relative paths up to one level deep are guaranteed match.
This will produce three files with concatenated contents:
style-group.css
/** css/style1.css **/
body { color: #000; }
/** css/style2.css **/
#main { background-color: #fff; }
script-group.js
/** js/script1.js **/
function onDomReady(){ ... }
/** js/script2.js **/
$(onDomReady);
style-group2.css
/** assets/style/main.css **/
body { font-weight: bold; }
/** assets/style/base.css **/
section { font-size: 15em; }
These will reside under the asset build directory in the base target directory by default. You can change the name
of this directory using the Concat.parentDir
SettingKey
.
