Reshd

Description

Reshd stands for remote Erlang shell daemon. It offers a telnet port into an Erlang shell in the Erlang node.

Screenshot (well, sort of)

Here is an example session. Italic text is text that has been typed in.

First we need to start the reshd:

    109> reshd:start(40044).
    {ok,40044}

Then we can connect:

    unixprompt% telnet localhost 40044
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    Eshell V5.0.1
    1> io:format("Hello world!~n").
    Hello world!
    ok
    2> exit().
    ** Terminating shell **
    Connection closed by foreign host.
    unixprompt%

There is also an Emacs package, resh, which provides means for connecting to the Erlang from within Emacs. Type as follows:

Connecting

Type M-x resh RET to connect to the erlang node.

Compilation buffer

Type C-c s in the resh-buffer to set the current buffer as the current inferior erlang compilation buffer. Now, when you type C-c C-k, the compilation command will go directly into that erlang node.

Download

Download the latest version: reshd-1.6.tar.gz (40 kB).

Reshd is also available on github

Reshd is written in Erlang, so you need to download and install a copy of Erlang on your machine first.

Caveats

• There is no tab completion and parentesis blinking like in the ordinary Erlang shell. However, if you use resh from within Emacs, to connect to the Erlang node, all your line editing wishes will be fullfilled.
• There is no authorization procedure, and the connection is not encrypted.
• There are no privileges. Any function in any module is callable for anyone.
