Origin

JRPC was written by Julien Delplanque, who designed it against the specification and left behind a test suite that is the specification's own example section. The history, the design and the copyright notice are his, and the MIT licence is unchanged.

It was forked from juliendelplanque/JRPC, which has had no change to library code since 2021 and whose CI stops at Pharo 10. Development continues here.

Features

• Client and Server support for JSON-RPC 2.0.
• Only depends on Pharo's built-in packages.
• Uses STONJSON to parse JSON internally.
• Transport agnostic (like JSON-RPC 2.0 spec claims).
• Can currently be used over
  • HTTP
  • TCP
• It is easy to add other transport layers.
• Optional data in the error object, describing what failed in the image, for servers that ask for it.
