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

This software was originally created as a replacement for a different shell made by Vladimir Dzhuvinov, in order to avoid Java, but has evolved since.


In addition to most of the features provided by its predecessor, you will 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

  • WebSocket (RFC 6455) can also be used as a transport rather than HTTP

  • even Language Server Protocol servers may be launched as a slave command

  • support for method name tab completion using OpenRPC discovery or file input


See the man page for information about usage. The rest of this README will concern itself with externalities.


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


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

Avoid libedit if you can, in general it works but at the moment history is acting up and I have no clue about fixing it. Multiline editing is also misbehaving there.

$ git clone --recursive https://git.janouch.name/p/json-rpc-shell.git
$ mkdir json-rpc-shell/build
$ cd json-rpc-shell/build
$ 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

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, WebSocket and LSP-like co-process interfaces. It responds to ping and date, supports OpenRPC discovery and it can serve static files.
