rmate
If you wish to activate TextMate from an ssh session you can do so by copying the rmate (ruby) script to the server you are logged into. The script will connect back to TextMate running on your Mac so you should setup an ssh tunnel (as your Mac is likely behind NAT):
ssh -R 52698:localhost:52698 user@example.org
This can be made permanent by adding a section to your ~/.ssh/config file
Host <host>
RemoteForward 52698 localhost:52698
or, if using unix sockets (available with OpenSSH v6.7 and above):
ssh -R /home/user/.rmate.socket:localhost:52698 user@example.org
Install
Rubygems
You can install rmate via gem:
gem install rmate
Updating to latest version can be done using:
gem update rmate
Standalone
Installing into ~/bin can be done using these two lines:
curl -Lo ~/bin/rmate https://raw.githubusercontent.com/textmate/rmate/master/bin/rmate
chmod a+x ~/bin/rmate
If ~/bin is not already in your PATH then you may want to add something like this to your shell startup file (e.g. ~/.profile):
export PATH="$PATH:$HOME/bin"
Usage
rmate [options] file
Call rmate --help for a list of options. Default options can be set in /etc/rmate.rc or ~/.rmate.rc, e.g.:
host: auto # Prefer host from SSH_CONNECTION over localhost
port: 52698
unixsocket: ~/.rmate.socket # Use this socket file if it exists
You can also set the RMATE_HOST, RMATE_PORT and RMATE_UNIXSOCKET environment variables.
