SVKBD: Simple Virtual Keyboard
|
||
=================================
|
||
|
||
This is a simple virtual keyboard, intended to be used in environments,
|
||
where no keyboard is available.
|
||
|
||
Installation
|
||
------------
|
||
|
||
$ make
|
||
$ make install
|
||
|
||
This will create by default `svkbd-intl`, which is svkbd using an international
|
||
layout with multiple layers and overlays, and optimised for mobile devices.
|
||
|
||
You can create svkbd for additional layouts by doing:
|
||
|
||
$ make LAYOUT=$layout
|
||
|
||
This will take the file `layout.$layout.h` and create `svkbd-$layout`.
|
||
`make install` will then pick up the new file and install it accordingly.
|
||
|
||
Layouts
|
||
---------
|
||
|
||
The following layouts are available:
|
||
|
||
* **Mobile Layouts:**
|
||
* ``mobile-intl`` - A small international layout optimised for mobile devices. This layout consists of multiple layers which
|
||
can be switched on the fly, and overlays that appear on long-press of certain keys, adding input ability for
|
||
diacritics and other variants, as well as some emoji. The layers are:
|
||
* a basic qwerty layer
|
||
* a layer for numeric input, arrows, and punctuation
|
||
* a layer for function keys, media keys, and arrows
|
||
* a cyrillic layer (ЙЦУКЕН based); the э key is moved to an overlay on е
|
||
* a dialer/numeric layer
|
||
* ``mobile-plain`` - This is a plain layout with only a qwerty layer and numeric/punctuation layer. It was
|
||
originally made for [sxmo](https://sr.ht/~mil/Sxmo/).
|
||
* **Traditional layouts**:
|
||
* ``en`` - An english layout without layers (QWERTY)
|
||
* ``de`` - A german layout (QWERTZ)
|
||
* ``ru`` - A russian layout (ЙЦУКЕН)
|
||
* ``sh`` - A serbo-croatian layout using latin script (QWERTZ)
|
||
|
||
Usage
|
||
-----
|
||
|
||
$ svkbd-mobile-intl
|
||
|
||
This will open svkbd at the bottom of the screen, showing the default
|
||
international layout.
|
||
|
||
$ svkbd-mobile-intl -d
|
||
|
||
This tells svkbd to announce itself being a dock window, which then
|
||
is managed differently between different window managers. If using dwm
|
||
and the dock patch, then this will make svkbd being managed by dwm and
|
||
some space of the screen being reserved for it.
|
||
|
||
$ svkbd-mobile-intl -g 400x200+1+1
|
||
|
||
This will start svkbd-intl with a size of 400x200 and at the upper left
|
||
window corner.
|
||
|
||
For layouts that consist of multiple layers, you can enable layers on program start through either the ``-l`` flag or
|
||
through the ``SVKBD_LAYERS`` environment variable. They both take a comma separated list of layer names (as defined in
|
||
your ``layout.*.h``). Use the ``↺`` button in the bottom-left to cycle through all the layers.
|
||
|
||
Some layouts come with overlays that will show when certain keys are hold pressed for a longer time. For
|
||
example, a long press on the ``a`` key will enable an overview showing all kinds of diacritic combinations for ``a``.
|
||
|
||
Overlay functionality interferes with the ability to hold a key and have it outputted repeatedly. You can disable
|
||
overlay functionality with the ``-O`` flag or by setting the environment variable ``SVKBD_ENABLEOVERLAYS=0``. There is
|
||
also a key on the function layer of the keyboard itself to enable/disable this behaviour on the fly. Its label shows
|
||
``≅`` when the overlay functionality is enabled and ``≇`` when not.
|
||
|
||
Notes
|
||
---------
|
||
|
||
This virtual keyboard does not actually modify the X keyboard layout, the ``mobile-intl``, ``mobile-plain`` and ``en`` layouts simply rely on a standard US QWERTY layout (setxkbmap us) being activated, the other layouts (``de``, ``ru``, ``sh``) require their respective XKB keymaps to be active.
|
||
|
||
If you use another XKB layout you will get unpredictable output that does not match the labels on the virtual keycaps!
