Terminal User Interface
-----------------------

The ``cylc tui`` command (Tui) replaces the old ``cylc monitor``. It provides a
tree view that is very similar to the Cylc UI and supports some control
functionality.

Performance
TUI currently refreshes its display every second. Large workflows which
change rapidly may evolve faster than TUI is able to keep pace with which
will cause TUI to freeze.

A more performant implementation which does not rely on a scheduled global
update will follow in due course.

GScan
The old ``cylc gscan`` GUI has been removed. You can now find the gscan
display on the left-hand side of the Cylc UI.

In a future release ``cylc tui`` will be able to list workflows in a similar
way.

There are two UI options available to monitor and control workflows at Cylc 8.


Cylc TUI
Cylc Tui
--------

Cylc TUI is a text based UI, available on the command line with
``cylc tui <workflow_id>``.
Cylc Tui (TUI = Terminal User Interface) is a command line version of the GUI
which comes packaged with the Cylc scheduler.

It remains in development, with smooth running with large workflows soon to be
resolved.
It can be used to monitor and control any workflows running under your user
account, trigger tasks, access log files and perform other common activities.

Cylc Web GUI
------------

Cylc 8 web GUI is available, both as a single user application, ``cylc gui``
and as a multi user hub, ``cylc hub``. Both are dependent on `Cylc UI Server`_ installation.
The Cylc GUI application is a monitoring and control application which runs in
a web browser, it is distributed in the `Cylc UI Server`_ package which comes
separately from the core scheduler.

Start the GUI server and open the web app in your browser by running
``cylc gui``.

Cylc 8 UI workflow tree view
The GUI displaying a workflow using the "tree" view.

See :ref:`UI_Server_config` for how to configure the GUI.

Launching the UI via the hub will require authentication.
The default Authenticator uses PAM to authenticate system users with their
username and password.
As some workflows can be very large, or even infinite, the GUI uses a "window"
system to determine what to display. For more information, see :ref:`n-window`.

Going via the hub unlocks the ability to grant other users the permission
to view and interact with workflows running under your account.
Site administrators will need to configure this, for more information
see :ref:`cylc.uiserver.multi-user`.

Cylc Hub
--------

Cylc 8 Hub authentication page
The Cylc 8 GUI can be deployed with Jupyter Hub to support multi-user access
where it is possible to grant users the permission to view and interact with
workflows running under other user accounts. In these deployments, users will
have to authenticate when they open the GUI in the browser.

See :ref:`UI_Server_config` for how to configure the GUI.
The central server is started by the ``cylc hub`` command.

As some workflows can be very large, or even infinite, the UI uses a "window"
system to determine what to display. For more information, see :ref:`n-window`.

The UI continues to be developed.

Tui
^^^

The Tui (terminal user interface) is a command line version of the Gui.
You can use it to monitor and control your workflows.

There has been a major update to Tui at Cylc 8.3.0, you can now use Tui to
browse your installed workflows. Tui is now able to keep up with larger
workflows which would previously have caused it to time out.
