+
+
+Form-binder is a micro data binding and validating framework, easy to use and hack.
+
+## Usage at a glance
+
+```scala
+import com.github.tminglei.bind.simple._
+
+val binder = FormBinder(messages, errsTree())
+
+val mappings = tmapping(
+  "id" -> long(),
+  "body" -> (expandJson() >-: tmapping(
+    "email" -> (required() >+: text(email())),
+    "price" -> (omitLeft("$") >-: float()),
+    "count" -> number().verifying(min(3), max(10))
+  ).label("xx").verifying { case (label, (email, price, count), messages) =>
+    if (price * count > 1000) {
+      Seq(s"$label: $price * $count = ${price * count}, too much!")
+    } else Nil
+  })
+)
+
+binder.bind(mappings, params).fold(
+  errors => errors,
+  { case (id, (email, price, count)) => 
+    // do something here
+  }
+)
+
+```
+
+1) define your binder
+2) define your mappings
+3) prepare your data
+4) bind and consume
+
+
+## Installation & Integration
+
+#### 1. Add the dependency to your sbt project file:
+
+```scala
+libraryDependencies += "com.github.tminglei" %% "form-binder" % "0.10.0"
+```
+
+#### 2. Define your helper trait:
+
+```scala
+object FormBinderSupport {
+  val BindMessagesKey = "__bind_messages"
+}
+
+trait FormBinderSupport extends I18nSupport { self: ScalatraBase =>
+  import FormBinderSupport._
+
+  before() {
+    request(BindMessagesKey) = Messages(locale, bundlePath = "bind-messages")
+  }
+
+  def binder(implicit request: HttpServletRequest) = FormBinder(bindMessages.get, errsTree())
+
+  ///
+  private def bindMessages(implicit request: HttpServletRequest): Messages = if (request == null) {
+    throw new ScalatraException("There needs to be a request in scope to call bindMessages")
+  } else {
+    request.get(BindMessagesKey).map(_.asInstanceOf[Messages]).orNull
+  }
+}
+```
+
+#### 3. Then, mix and use it in your app codes:
+
+```scala
+import org.scalatra.ScalatraServlet
+import com.github.tminglei.bind.simple._
+
+class SampleServlet extends ScalatraServlet with FormBinderSupport {
+
+  get("/:id") {
+    val mappings = tmapping(
+      "id" -> long()
+    )
+    binder.bind(mappings, data(multiParams)).fold(
+      errors => holt(400, errors),
+      { case (id) =>
+        Ok(toJson(repos.features.get(id)))
+      }
+    )
+  }
+}
+```
+
+That's it. _See the [project site](https://github.com/tminglei/form-binder) for more details._
