termite/README.rst

A keyboard-centric VTE-based terminal, aimed at use within a window manager
with tiling and/or tabbing support.

Termite looks for the configuration file in the following order:
``$XDG_CONFIG_HOME/termite/config``, ``~/.config/termite/config``,
``$XDG_CONFIG_DIRS/termite/config``, ``/etc/xdg/termite/config``.

Termite's exit status is 1 on a failure, including a termination of the child
process from an uncaught signal. Otherwise the exit status is that of the child
process.

DEPENDENCIES
============

The `vte-ng <https://github.com/thestinger/vte-ng>`_ project is required until
VTE exposes the necessary functions for keyboard text selection and URL hints
(if ever). A simple patch `has been submitted upstream
<https://bugzilla.gnome.org/show_bug.cgi?id=679658#c10>`_ but they're unwilling
to expose functionality that's not required by GNOME Terminal even if there's
no extra maintenance (it already exists internally) and no additional backwards
compatibility hazards.

If no browser is configured and $BROWSER is unset, xdg-open from xdg-utils is
used as a fallback.

.. [1] The directory can be set by a process running in the terminal. For
       example, with zsh:

       .. code:: sh

            if [[ $TERM == xterm-termite ]]; then
              . /etc/profile.d/vte.sh
              __vte_osc7
            fi
       ::

       For example, with bash:

       .. code:: sh

            if [[ $TERM == xterm-termite ]]; then
              . /etc/profile.d/vte.sh
              __vte_prompt_command

+-----------------------------------+-----------------------------------------------------------+

During scrollback search, the current selection is changed to the search match
and copied to the PRIMARY clipboard buffer.

With the text input widget focused, up/down (or tab/shift-tab) cycle through
completions, escape closes the widget and enter accepts the input.

In hints mode, the input will be accepted as soon as termite considers it a
unique match.

PADDING
=======

Internal padding can be added by using CSS to style the VTE widget. Adding the
follow snippet to ``$XDG_CONFIG_HOME/gtk-3.0/gtk.css`` (or
``~/.config/gtk-3.0/gtk.css``) will add uniform 2px padding around the edges:

.. code:: css

    VteTerminal {
        padding: 2px;
    }

This can also be used to add varying amounts of padding to each side via
standard usage of the CSS padding property.
