Standalone

rmate is a single file script, so you can simply download it to a location in your PATH. For example, assuming /usr/local/bin is in the PATH

wget https://raw.githubusercontent.com/sclukey/rmate-python/master/bin/rmate
chmod +x ./rmate
mv ./rmate /usr/local/bin/rmate

PyPI

You can also install rmate with pip

pip install rmate

SSH Connection Settings

For rmate to be able to connect back to TextMate, a port must be tunneled through the ssh connection. By default, rmate uses port 52698, and the port can be tunneled for an individual connection on the command line

ssh -R 52698:localhost:52698 user@example.com

or for all connections by adding a rule to your ~/.ssh/config

Host *
RemoteForward 52698 localhost:52698
