rsub 1.0.2

Open and edit files from a remote machine in your local Sublime Text or TextMate 2.

With rsub you can open and edit files from a remote machine (you’re connected via SSH) in your local Sublime Text* or TextMate 2. No need to setup a shared filesystem or anything like that, just a SSH tunnel!

This script is a port of the original rmate.

* To get it work on Sublime Text you need `rsub-plugin <https://github.com/jirutka/rsub-plugin>`__.

Installation

The rsub requires Python 2.7+ or 3.× and module docopt 0.4.0+.

System-wide

Install from PyPi system-wide:

sudo pip install rsub

…or manually:

git clone [e-mail]:jirutka/rsub-client.git
cd rsub-client
sudo ./setup.py install
cd .. && rm -Rf rsub-client

Locally

If you don’t have root access to the system, or just don’t want to install rsub system-wide, then you can tell pip or setup.py to install rsub into your home directory (namely ~/.local):

pip install --user rsub

…or manually:

git clone [e-mail]:jirutka/rsub-client.git
cd rsub-client
./setup.py --user install
cd .. && rm -Rf rsub-client

The rsub script should be installed in ~/.local/bin. If you want to make it accessible from anywhere, add this directory to your PATH (choose one according to shell you’re using):

echo 'export PATH=$HOME/.local/bin:$PATH' >> ~/.bashrc                   # bash
echo 'export PATH=$HOME/.local/bin:$PATH' >> ~/.zshrc                    # zsh
echo 'set -x PATH $HOME/.local/bin $PATH' >> ~/.config/fish/config.fish  # fish

Usage

You can use rsub --help to see the usage:

Usage:
  rsub [options] [-l NUM] [-m NAME] [-t TYPE] -
  rsub [options] [-l NUM...] [-m NAME...] [-t TYPE...] FILE...

  -                     Read from the standard input.
  FILE                  File to open (will be created if does not exist yet).

  -l NUM --line=NUM     Place caret on line [NUM] after loading the file.
  -m NAME --name=NAME   The display name shown in editor.
  -t TYPE --type=TYPE   Treat file as having [TYPE] (e.g. rb, py, md).

Options:
  -H HOST --host=HOST   Connect to host. Use 'auto' to detect the host from SSH.
  -p PORT --port=PORT   Port number to use for connection.
  -w --wait             Wait for file(s) to be closed by the editor.
  -f --force            Open even if the file is not writable.
  -v --verbose          Verbose logging messages.
  -h --help             Show this message and exit.
  --version             Show version and exit.

Default options can be set in /etc/rsubrc and ~/.rsubrc (or /etc/rmate.rc and ~/.rmate.rc for compatibility with original rmate):

host = auto  # prefer host from SSH_CONNECTION over localhost
port = 52698

You can also set the RSUB_HOST and RSUB_PORT (or RMATE_HOST and RMATE_PORT) environment variables.

Setting up the connection

To do its job, rsub needs a connection back to your computer so that it can talk to Sublime Text or TextMate. There are multiple ways you can accomplish this, but probably the best way is to use a reverse SSH tunnel:

ssh -R 52698:localhost:52698 example.com

The -R option sets up a reverse tunnel. The first 52698 names a port on the remote. It will be connected to localhost:52698 or the same port on the connecting box. That port number is the default for Sublime Text, TextMate 2 and rsub. To test things out, launch Sublime Text or TextMate 2 on your local machine and run a command like this on the remote:

rsub test.md

After you verify that things are working, feel free to update your SSH setting to automatically setup the tunnel without you needing to supply the -R arguments all the time.

For a single server just add an entry like the following to your ~/.ssh/config:

Host example.com
RemoteForward 52698 localhost:52698

If you want to make those settings the default for all of your servers, use the wildcard host:

Host *
RemoteForward 52698 localhost:52698
