# capnproto-java: Cap'n Proto for Java

This is an experimental pure Java implementation of [Cap'n Proto](http://capnproto.org).

It doesn't do much yet.

## getting started

You will need [SBT](http://scala-sbt.org). We recommend [this version](https://github.com/paulp/sbt-extras).

To compile:
```
$ sbt compile
```

To read a message:
```
$ echo '(people = [(id = 123, name = "Alice", email = "alice@example.com", employment = (school = "MIT"))])' \
 | capnp encode examples/src/main/schema/addressbook.capnp AddressBook \
 | java -cp runtime/target/scala-2.11/classes:examples/target/scala-2.11/classes/ \
   org.capnproto.examples.AddressbookMain read
```

To write a message:
```
$ java -cp runtime/target/scala-2.11/classes:examples/target/scala-2.11/classes/  \
  org.capnproto.examples.AddressbookMain write \
  | capnp decode examples/src/main/schema/addressbook.capnp AddressBook
```

To generate IntelliJ project files, do `sbt update gen-idea`.
