bunkchat is ultra-simple, local-only group chat for tilde servers written in posix sh

install

git clone https://git.bunk.computer/bunk/bunkchat.git && \
cd ./bunkchat && \
sudo ./install.sh

usage

bunkchat is comprised of three separate programs

1. proclaim - post in chat
2. heed - read current chat
3. scry - read old chat

run proclaim and heed in adjacent terminals for best ux

security

hopefully!

• the chat log is append only, but anyone can append anything to it
• proclaim only accepts user input with read -r, which does not expand variables, and appends to the chat log with echo "$userinput" >> $chatlog
• heed only does tail -f on the chat log
• scry only opens the chat log with less
• no one has execute permissions on the chat log

if you find a security issue, please contact us

notes

bunkchat is one large group chat that every user on the server is part of

if your file system does not support setting append only permissions with chattr +a, install.sh will fail

bunkchat should work on all standard linuces. not tested on bsd
