~ said everyone before gumd
v.0.0.9

python3 -mpip install gumd
Use gumd (Daemon) programmatically
>>>> from gumd import GumD
>>>> gumd =GumD('235.35.3.5:3535',1)
>>>> gumd.mcast("/home/a/stuff")
stream uri: udp://@235.35.3.5:3535
>>>>
Use gumc (Client) programmatically
>>>> from gumc import GumC
>>>> gumc = GumC("udp://@235.35.3.5:3535")
>>>> data = gumc.read(8)
>>>> data
b'Helloooo'
Cli tools
- The cli tools gumd and gumc try to install to ~/.local/bin
- make sure ~/.local/bin is in your path I have this at the end my .bashrc
PLAN9=/home/a/plan9port export PLAN9
PATH=/home/a/.local/bin:$PLAN9:$PATH export PATH
if you dont get them installed, roll your own.
- gumd (Daemon)
#!/usr/bin/env python3
from gumd import cli
cli()
- gumc (Client)
#!/usr/bin/env python3
