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
