For example, you use a Linux as a virtual machine on Windows host. You connect to Linux by SSH client(e.g. PuTTY). When you want to copy text of a file on Linux to Windows, what do you do? One solution is doing cat file.txt and drag displayed text. But this answer is NOT elegant! Because your hand leaves from the keyboard to use the mouse.

Another solution is using the Lemonade. You input cat file.txt | lemonade copy. Then, lemonade copies text of the file to clipboard of the Windows!

In addition to the above, lemonade supports pasting and opening URL.

On server (in the above, Windows)

$ lemonade server

Client (in the above, Linux)

# You want to copy a text
$ cat file.txt | lemonade copy

# You want to paste a text from the clipboard of Windows
$ lemonade paste

# You want to open an URL to a browser on Windows.
$ lemonade open 'http://google.com'

Configuration

You can override command line options by configuration file. There is configuration file at ~/.config/lemonade.toml.

Server

port = 1234
allow = '192.168.0.0/24'

port is a listening port of TCP.
allow is a comma separated list of a allowed IP address(with CIDR block).

Client

port = 1234
host = '192.168.x.x'
trans-loopback = true
trans-localfile = true

port is a port of server.
host is a hostname of server.
trans-loopback is a flag of translation loopback address.
trans-localfile is a flag of translation localfile.

Detail of trans-loopback and trans-localfile are described Advanced Usage.

Advanced Usage

trans-loopback

Default: true

This option works with open command only.

If this option is true, lemonade translates loopback address to address of client.

For example, you input lemonade open 'http://127.0.0.1:8000'. If this option is false, server receives loopback address. But this isn't expected. Because, at server, loopback address is server itself.

If this option is true, server receives IP address of client. So, server can open URL!

trans-localfile

Default: true

This option works with open command only.

If this option is true, lemonade translates path of local file to address of client.

For example, you input lemonade open ./file.txt. If this option is false, server receives ./file.txt. But this isn't expected. Because, at server, ./file.txt doesn't exist.

If this option is true, server receives IP address of client. And client serve the local file. So, server can open the local file!

Alias

You can use lemonade as a xdg-open, pbcopy and pbpaste.

For example.

$ ln -s /path/to/lemonade /usr/bin/xdg-open
$ xdg-open  'http://example.com' # Same as lemonade open 'http://example.com'
