SSHubl

A Sublime Text 4+ plugin for your SSH connections

Introduction

This plugin aims to grant the power of (Open)SSH to Sublime Text. Included features are :

• Open a remote terminal
• Open a remote folder over sshfs
• Open forward and reverse ports (or UNIX domain sockets)
• Automatic environment re-setup on project opening

It has been inspired by Visual Studio Code Remote - SSH plugin, without the drawback of depending on a remote agent running on the SSH server.

Dependencies

• Sublime Text 4081+
• OpenSSH client
• sshfs (FUSE) client
• pexpect Python package (used for non-interactive SSH connection on Linux/macOS)
• Terminus Sublime Text package (used for remote terminal feature on Linux/macOS, required on Windows)

On Debian : apt-get install -y sshfs

Installation

With Package Control (recommended)

1. Open your command palette and type in : Package Control: Install Package
2. Browse the list or search for SSHubl
3. Press Enter and you're done !

Package Control dedicated page here.

Manually

1. Go to the Sublime Text packages folder (usually $HOME/.config/sublime-text/Packages/ or %AppData%\Sublime Text\Packages\)
2. Clone this repository there : git clone https://github.com/HorlogeSkynet/SSHubl.git
3. [Linux/macOS] Satisfy either pexpect and ptyprocess third-party dependencies in Sublime Text Lib/python38/ folder (see here for further information) or Terminus Sublime Text package dependency
4. [Windows] Satisfy Terminus Sublime Text package dependency
5. Restart Sublime Text and… :tada:

Usage

Open your command palette and type in SSHubl to select Connect to server. Once connected, you will be able to select Forward port/socket, Open/Select directory (mount sshfs) or even Open a terminal commands.

Frequently Asked Questions

Why can I non-interactively connect to new hosts without accepting their fingerprint ?

pexpect package is known to always accept remotes' public key, and it isn't configurable.

How is “SSHubl” pronounced ?

[ʃʌbəl]

Why haven't you opted for a pure Python approach ?

Paramiko doesn't support FUSE. There is also fs.sshfs, but it relies on PyFilesystem 2 which doesn't support “re-exposing” FUSE as local mount point.

Is SSHubl compatible with other SSH clients ?

As it uses OpenSSH connections multiplexing feature, no.

Do you plan to support Sublime Text 3 ?

It's very unlikely as SSHubl requires Python 3.8 runtime and depends on several Sublime Text 4081+ API.
