json-rpc-shell

json-rpc-shell is a simple shell for running JSON-RPC 2.0 queries.

This software has been created as a replacement for the following shell, which is written in Java: http://software.dzhuvinov.com/json-rpc-2.0-shell.html

Features

In addition to most of the features provided by Vladimir Dzhuvinov's shell you get the following niceties:

• configurable JSON syntax highlight, which with prettyprinting turned on helps you make sense of the results significantly

• ability to pipe output through a shell command, so that you can view the results in your favourite editor or redirect them to a file

• ability to edit the input line in your favourite editor as well with Alt+E

Supported transports

• HTTP

• HTTPS

• WebSocket

• WebSocket over TLS

WebSockets

The JSON-RPC 2.0 spec doesn't say almost anything about underlying transports. The way it's implemented here is that every request is sent as a single text message. If it has an "id" field, i.e. it's not just a notification, the client waits for a message from the server in response.

There's no support so far for any protocol extensions, nor for specifying the higher-level protocol (the "Sec-Ws-Protocol" HTTP field).

Packages

Regular releases are sporadic. git master should be stable enough. You can get a package with the latest development version from Archlinux's AUR.

Building and Usage

Build dependencies: CMake, pkg-config, help2man, liberty (included), http-parser (included)
Runtime dependencies: libev, Jansson, cURL, openssl, readline or libedit >= 2013-07-12,

$ git clone --recursive https://git.janouch.name/p/json-rpc-shell.git
$ mkdir json-rpc-shell/build
$ cd json-rpc-shell/build
$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug
$ make

To install the application, you can do either the usual:

# make install

Or you can try telling CMake to make a package for you. For Debian it is:

$ cpack -G DEB
# dpkg -i json-rpc-shell-*.deb

Note that for versions of CMake before 2.8.9, you need to prefix cpack with fakeroot or file ownership will end up wrong.

Run the program with --help to obtain usage information.

Test server

If you install development packages for libmagic, an included test server will be built but not installed which provides a trivial JSON-RPC 2.0 service with FastCGI, SCGI, and WebSocket interfaces. It responds to the ping method.
