2ipty

2ipty is a pseudo terminal that reads a fifo and your terminal for input. It can be useful for terminal applications that you may want to control with some keybinding. I use this with mpsyt, which I use as a music player. Sometimes I want to play/pause without looking for the terminal window with mpsyt. To do this, I bound the XF86AudioPlay key to echo -ne ' ' > /tmp/my-mpsyt.fifo (in my i3config). Now, when I press XF86AudioPlay anywhere or the space bar in the player, the music is played or paused.

Ussage

2ipty <cmd> <input path>

Example

tty1:

$ 2ipty python /tmp/toto.fifo
>>> print("This is typed into tty1")
This is typed into tty1
>>> print("This is from /tmp/toto.fifo")
This is from /tmp/toto.fifo
>>>

tty2:

$ echo 'print("This is from /tmp/toto.fifo")' > /tmp/toto.fifo
