scripts/weechat-open-url

#!/bin/bash
## A script to handle opening urls from weechat in tmux, possibly on host maching
## Inspired by https://toxicfrog.github.io/remote-url-handling-in-weechat-and-tmux/
##
## This script is relying on the laptop opening a reverse ssh tunnel to the server
##
## Add binding for M-o #, for 1 through 9 (10 can be 0)
## /key bind meta-o1 /url_hint_replace /exec -bg weechat-open-url {url1}
## /key bind meta-o2 /url_hint_replace /exec -bg weechat-open-url {url2}
##
## You can chose between a split (split-window -h) or new (new-window) in tmux
