JarCasting
Pine is a functional HTML5 and XML library for the Scala platform. It supports parsing, manipulating and rendering of HTML. Pine provides type-safe bindings for HTML5 generated from MDN. Tree nodes are immutable and can be constructed from compile-time or runtime HTML/XML content. The tree may be manipulated and rendered back as HTML or as a browser node.
Features
- Immutable and typed trees
- Type-safe bindings, generated from MDN
- Support for custom elements and attributes
- HTML5 and XML parser based on recursive descent
- Macros for compile-time HTML string/file parsing
- Tree manipulation
- Rendering as HTML strings
- DSL for common operations
- Unit and property-based tests
- Few dependencies
JavaScript back end
- Rendering as DOM nodes
- Updating nodes in DOM
- DSL for attaching/detaching events
Compatibility
| Platform | Platform version | Scala versions |
|---|---|---|
| JVM | 2.11 (T), 2.12 (T), 2.13 (L) | |
| Scala.js | 1.0 | 2.12 (T), 2.13 (L) |
| Scala Native | 0.4.0-M2 | 2.11 (T) |
- (T): Typelevel Scala
- (L): Lightbend Scala
Examples
import pine._
val url = "http://github.com/"
val root = html"<a href=$url>GitHub</a>"
println(root.toHtml) // <a href="http://github.com/">GitHub</a>
JavaScript
import pine.dom._
println(root.toDom) // [object HTMLAnchorElement]
sbt
Pine makes use of a language extension called literal types, see SIP-23. For Scala 2.11 and 2.12, only Typelevel Scala implements this feature. However, it is available in Lightbend Scala from 2.13 onwards.
2.13 onwards
scalaVersion := "2.<version>"
libraryDependencies += scalaOrganization.value % "scala-reflect" % scalaVersion.value
< 2.13
scalaVersion := "2.12.4-bin-typelevel-4" // or "2.11.11-bin-typelevel-4"
scalaOrganization := "org.typelevel"
scalacOptions += "-Yliteral-types"
libraryDependencies += scalaOrganization.value % "scala-reflect" % scalaVersion.value
Scala.js settings
libraryDependencies := libraryDependencies.value.filterNot(_.name == "scalajs-compiler")
addCompilerPlugin("org.scala-js" % "scalajs-compiler" % scalaJSVersion cross CrossVersion.patch)
Scala Native settings
libraryDependencies := libraryDependencies.value.filterNot(_.name == "nscplugin")
addCompilerPlugin("org.scala-native" % "nscplugin" % nativeVersion cross CrossVersion.patch)
Dependencies
libraryDependencies += "tech.sparse" %% "pine" % "<version>" // JVM
libraryDependencies += "tech.sparse" %%% "pine" % "<version>" // JavaScript, Native
