ftp

lightweight RFC959 FTP server written in crystal lang

Note from the creator

Hello guys! ;)

This little baby is still under development. My goal is to make a shard of it once totally finished.

Actually, it's my first project written in Crystal : feel free to contribute, or to send tips ! I'm doing it only to train myself.

And don't hesitate to give a star if you like it, of course!

Installation

1. Add the dependency to your shard.yml:

dependencies:
  ftp:
    github: LeChatErrant/ftp

1. Run shards install

Usage

require "ftp"

server = Ftp::FTPServer.new(8000, "/home")
server.start
sleep

Run example

You can find an example of utilisation at the root of the repository

To try it, simply run crystal build example.cr --release

Then you can execute it with ./example port root_directory

This will run a FTP server, listening on the specified port and mounted on 'root_directory'
