Quickstart

If you simply want to try pelo without having to build all the dependencies, run:

docker run --security-opt seccomp=unconfined ebzzry/pelo 8.8.8.8

If you’re satisfied, you may create a shell function:

pelo () { docker run --security-opt seccomp=unconfined ebzzry/pelo $@; }

a shell alias:

alias pelo="docker run --security-opt seccomp=unconfined ebzzry/pelo"

or even a script in ~/bin:

cat > ~/bin/pelo << MEH
#!/usr/bin/env bash
docker run --security-opt seccomp=unconfined ebzzry/pelo $@
MEH
chmod +x ~/bin/pelo

Installation

Install the dependencies using the following commands, on Debian and NixOS systems, respectively:

sudo apt-get install -y curl sbcl cl-launch make git iputils-ping sox

nix-env -i curl sbcl cl-launch gnumake git iputils sox

Then, install pelo:

mkdir -p ~/bin ~/common-lisp
git clone https://github.com/fare/asdf ~/common-lisp/asdf
git clone https://github.com/zhaqenl/pelo ~/common-lisp/pelo
curl -O https://beta.quicklisp.org/quicklisp.lisp
sbcl --noinform --load quicklisp.lisp --eval  '(quicklisp-quickstart:install)' --eval '(let ((ql-util::*do-not-prompt* t)) (ql:add-to-init-file) (sb-ext:exit))'
sbcl --noinform --eval "(progn (mapc #'ql:quickload '(:inferior-shell :clon :cl-launch :fare-utils :cl-scripting)) (sb-ext:exit))"
make -C ~/common-lisp/pelo install

The executable program will then be available at:

~/bin/pelo

Docker

To build the Docker image, run the following command inside the repository directory:

docker build -t ogag/pelo .

To test it out:

docker run --security-opt seccomp=unconfined ogag/pelo --help
