A terminal embedded in Nautilus, the GNOME’s file browser

Nautilus Terminal is a terminal embedded into Nautilus, the GNOME’s file browser. It is always opened in the current folder, and follows the navigation (the cd command is automatically executed when you navigate to another folder).

NOTE: This is a complete re-implementation of my previous Nautilus Terminal plugin <https://launchpad.net/nautilus-terminal>__.

Main Features

• Embed a Terminal in each Nautilus tab / window,
• Follows the navigation: if you navigate in Nautilus, the cd command is automatically executed in the terminal,
• Can be displayed / hidden using the F4 key (configurable),
• Configurable: font, background and text color, terminal position (displayed at top or at bottom of the windows),...
• Supports copy / paste through contextual menu and Ctrl+Shift+C / Ctrl+Shift+V,
• Supports drag & drop of file on the terminal,
• ...

If you want to read more about this project and its history, I wrote an article on my blog (it is in French, but Google Translate should help) : Nautilus Terminal: The story of a complicated project <https://blog.flozz.fr/2018/12/17/nautilus-terminal-lhistoire-dun-projet-complique/>__.

Trouble Shooting
----------------

Nautilus Terminal Doesn't show up

Nautilus Terminal Doesn't show up? Here are a bunch of things to check before opening an issue:

• Try to restart Nautilus::

    nautilus -q
  

• Try to restart Nautilus and keep it attached to a terminal to catch eventual error messages::

    nautilus -q && nautilus
  

• Check that the extension is properly installed with one of the following commands::

    nautilus-terminal --check
    python3 -m nautilus_terminal --check
  

  If everything is OK, the output should be::

    Nautilus Python: Installed
    Nautilus Terminal Extension: Installed
  

  If there is any error, you will have an help message similar to this one to tell you how to fix::

    Nautilus Python: Installed
    Nautilus Terminal Extension: Absent
        Please install the Nautilus Extension with one of the following commands:
        System-wide: sudo nautilus-terminal --install-system
        Current user: nautilus-terminal --install-user
        NOTE: you may need to replace the 'nautilus-terminal' command by 'python3 -m nautilus_terminal'.
  

• Try to get some logs from Nautilus::

    nautilus -q && nautilus
  

Nautilus crashes at startup

If Nautilus crashes at startup, the first thing to do is to get some logs. Run
it from a terminal with the following command and check if there is something
useful in the logs::

    nautilus -q ; nautilus

If you see an error similar to this one::

    (org.gnome.Nautilus:9812): GLib-GIO-ERROR **: 18:42:59.373: Settings schema 'org.flozz.nautilus-terminal' does not contain a key named 'default-focus-terminal'

It means that an older version of the GSettings schema is installed. Search for
the following files on your system and removes them:

* ``/usr/share/glib-2.0/schemas/org.flozz.nautilus-terminal.gschema.xml``
* ``/usr/local/share/glib-2.0/schemas/org.flozz.nautilus-terminal.gschema.xml``
* ``~/.local/share/glib-2.0/schemas/org.flozz.nautilus-terminal.gschema.xml``

Once done, recompile GSettings databases with the following commands (depending
on which files you found)::

    sudo glib-compile-schemas /usr/local/share/glib-2.0/schemas
    sudo glib-compile-schemas /usr/share/glib-2.0/schemas
    glib-compile-schemas ~/.local/share/glib-2.0/schemas/

Once done, reinstall the schema with one of the following commands::

   # For system-wide install (recommended)
   sudo nautilus-terminal --install-system

   # For user install
   python3 -m nautilus_terminal --install-user

Finally restart Nautilus.


Detect if running inside nautilus-terminal

To detect whether the shell is running inside nautilus-terminal, there is an environment variable exposed when executing the shell::

INSIDE_NAUTILUS_PYTHON=1

It is useful in case you want to avoid running things inside the nautilus-terminal::

~/.bashrc:

Run termux only if not inside nautilus-terminal

if [ -z "$INSIDE_NAUTILUS_PYTHON" ]; then tmux -attach fi

Reporting an issue

If none of the above worked, please `open an issue
<https://github.com/flozz/nautilus-terminal/issues>`_ with as much information
as possible:

* How did you installed Nautilus Terminal,
* What you tried,
* Any error message outputted during the installation or by Nautilus,
* When possible, please include the output of one of the following command::

        nautilus-terminal --print-debug
        python3 -m nautilus_terminal --print-debug


Hacking and Debug
-----------------

If you want work on this software, you will first have to install the
dependencies listed above.

This extension comes in two parts: a conventional Python module
(``nautilus_terminal``), and a small bit of bootstrap code that’s loaded
by ``python-nautilus`` when Nautilus starts up
(``nautilus_terminal_extension.py``). The bootstrap code must be
installed where ``python-nautilus`` can find it before you can start
making changes and testing them::

   python3 -m nautilus_terminal --install-user  # Current user only
   sudo python3 -m nautilus_terminal --install-system  # System-wide

When the bootstrap is loaded into Nautilus, it imports the Python module
from either the normal ``PYTHONPATH``, or from your working copy of this
repository if the right debug environment is set.

With the bootstrap installed, you can use the following script to test
new code in Nautilus without having to reinstall the module::

   tools/debug-in-nautilus.sh
   tools/debug-in-nautilus.sh --no-bg  # keep Nautilus attached to the console

When you start working on this extension, you will have to compile the
GSettings schema (and you will have to recompile it each time you modify the
``nautilus_terminal/schemas/org.flozz.nautilus-terminal.gschema.xml`` file)::

   glib-compile-schemas nautilus_terminal/schemas/

Running lint and tests::

   pip3 install nox
   python3 -m nox -s lint
   python3 -m nox -s test

Happy hacking! :)


Packaging This Software
-----------------------

If you want to package this software for a Linux distribution, here are some
useful information for you:

* You can use the ``python3 setup.py install --root /tmp/foo/bar`` command to
  perform a system-wide-like install in the specified folder.

* You should remove the ``nautilus_terminal/not_packaged.py`` file from your
  package. Removing this file will disable options that allow user to modify
  its installation (``--install-*`` and ``--uninstall-*`` options of the
  ``nautilus-terminal`` command).
