"""
Opens links in a browser.
Installation
------------
First use case: local use
~~~~~~~~~~~~~~~~~~~~~~~~~
If you use poezio on your workstation, this is for you.
You only have to load the plugin: ::
/load link
Second use case: remote use
~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you use poezio through SSH, this is for you.
.. note:: Small explanation: Poezio will create a `Unix FIFO`_ and send the commands in,
and you will have to run a dæmon locally with ssh, to get those commands.
First, set the :term:`exec_remote` option in the config file to ``true``. Then select
the directory you want to put the fifo in (default is the current
directory, :file:`./`), the :file:`poezio.fifo` file will be created there.
After that, load the plugin: ::
/load link
And open a link with :term:`/link` (as described below), this will create the FIFO.
You need to grab poezio’s sources on your client computer, or at least the `daemon.py`_
file.
Finally, on your client computer, run the ssh command:
.. code-block:: bash
ssh toto@example.org "cat ~/poezio/poezio.fifo" | python3 daemon.py
Usage
-----
.. glossary::
/link
**Usage:** ``/link [range]``
This plugin adds a :term:`/link` command that will open the links in ``firefox``. If
you want to use another browser, you can use the :term:`/set` command to change the
:term:`browser` option.
:term:`/link` without argument will open the last link found
in the current tab, if any is found. An optional range
argument can be given, to select one or more links to
open. Examples:
``/link 1`` is equivalent to ``/link``
``/link 3`` will open the third link found in the current tab,
starting from the bottom.
``/link 1:5`` will open the last five links in the current tab
``/link :2`` will open the last two links
Options
-------
:term:`exec_remote`
To execute the command on your client
