Efene Shell¶

Efene provides a shell (or REPL) similar to the one provided by Erlang.

To get it you need to download and build efene:

git clone https://github.com/efene/efene
cd efene
make

And then run:

./fnshell

You will see something like:

$ ./fnshell

Erlang/OTP 18 [erts-7.0] [source] [64-bit] [smp:4:4] [async-threads:10] [kernel-poll:false]

efene shell (call q() to quit, help() for help, Ctrl+g for Job Control Mode)

>>>

As the banner says, write q() and press enter to quit, write help() and press enter to see other builtin functions, if you press Ctrl+g you enter erlang’s Job Control Mode, see “JCL Mode” section in the shell manual page from the erlang documentation for more details of what you can do there.

You can symlink fnshell from a place in your $PATH to be able to run it from any folder, for example:

mkdir -p ~/bin
cd ~/bin
ln -s path/to/efene/fnshell

Note

Change path/to/fnshell to the actual path where you have the fnshell file

Add ~/bin to your $PATH if you don’t have it already:

export PATH=$PATH:$HOME/bin

Add it to your shell rc file to have it permanently set (.zshrc for zsh, .bashrc for bash)
