SpaceCadet
Space Cadet is a way to make it more convenient to input
parens - those (
and )
things -, symbols that a lot of programming languages
use frequently. If you are working with Lisp, you are using these all the time.
What it does, is that it turns your left and right Shift
keys into parens if
you tap and release them, without pressing any other key while holding them.
Therefore, to input, say, (print foo)
, you don't need to press Shift
, hold
it, and press 9
to get a (
, you simply press and release Shift
, and
continue writing. You use it as if you had a dedicated key for parens!
But if you wish to write capital letters, you hold it, as usual, and you will
not see any parens when you release it. You can also hold it for a longer time,
and it still would act as a Shift
, without the parens inserted on release:
this is useful when you want to augment some mouse action with Shift
, to
select text, for example.
After getting used to the Space Cadet style of typing, you may wish to enable
this sort of functionality on other keys, as well. Fortunately, the Space Cadet
plugin is configurable and extensible to support adding symbols to other keys.
Along with (
on your left Shift
key and )
on your right Shift
key,
you may wish to add other such programming mainstays as {
to your left-side cmd
key,
}
to your right-side alt
key, [
to your left Control
key, and ]
to your right
Control
key. You can map the keys in whatever way you may wish to do, so feel free to
experiment with different combinations and discover what works best for you!
Using the plugin
Using the plugin with its defaults is as simple as including the header, and enabling the plugin:
#include <Kaleidoscope.h>
#include <Kaleidoscope-SpaceCadet.h>
KALEIDOSCOPE_INIT_PLUGINS(SpaceCadet);
void setup() {
Kaleidoscope.setup();
}
This assumes a US QWERTY layout on the host computer, though the plugin sends the correct keymap code for each symbol. Because the mapping is entirely configurable, though, you may switch out keys at your leisure.
If you wish to enable additional modifier keys (or disable the default behavior for the shift and parentheses combinations), configuration is as simple as passing a new keymap into the SpaceCadet object, as shown below:
#include <Kaleidoscope.h>
#include <Kaleidoscope-SpaceCadet.h>
KALEIDOSCOPE_INIT_PLUGINS(SpaceCadet);
void setup() {
Kaleidoscope.setup();
//Set the keymap with a 250ms timeout per-key
//Setting is {KeyThatWasPressed, AlternativeKeyToSend, TimeoutInMS}
//Note: must end with the SPACECADET_MAP_END delimiter
static kaleidoscope::plugin::SpaceCadet::KeyBinding spacecadetmap[] = {
{Key_LeftShift, Key_LeftParen, 250}
, {Key_RightShift, Key_RightParen, 250}
, {Key_LeftGui, Key_LeftCurlyBracket, 250}
, {Key_RightAlt, Key_RightCurlyBracket, 250}
, {Key_LeftAlt, Key_RightCurlyBracket, 250}
, {Key_LeftControl, Key_LeftBracket, 250}
, {Key_RightControl, Key_RightBracket, 250}
, SPACECADET_MAP_END
};
//Set the map.
SpaceCadet.map = spacecadetmap;
}
Plugin methods
The plugin provides the SpaceCadet
object, with the following methods and
properties:
.map
Set the key map. This takes an array of
kaleidoscope::plugin::SpaceCadet::KeyBinding
objects with the specialSPACECADET_MAP_END
sentinel to mark the end of the map. Each KeyBinding object takes, in order, the key that was pressed, the key that should be sent instead, and an optional per-key timeout overrideIf not explicitly set, defaults to mapping left
shift
to(
and rightshift
to)
.
kaleidoscope::plugin::SpaceCadet::KeyBinding
An object consisting of the key that is pressed, the key that should be sent in its place, and the timeout (in milliseconds) until the key press is considered to be a "held" key press. The third parameter, the timeout, is optional and may be set per-key or left out entirely (or set to
0
) to use the default timeout value.
.time_out
Set this property to the number of milliseconds to wait before considering a held key in isolation as its secondary role. That is, we'd have to hold a
Shift
key this long, by itself, to trigger theShift
role in itself. This timeout setting can be overridden by an individual key in the keymap, but if it is omitted or set to0
in the key map, the global timeout will be used.Defaults to 1000.
.enable()
This method enables the SpaceCadet plugin. This is useful for interfacing with other plugins or macros, especially where SpaceCadet functionality isn't always desired.
The default behavior is
enabled
.
.disable()
This method disables the SpaceCadet behavior. This is useful for interfacing with other plugins or macros, especially where SpaceCadet functionality isn't always desired.
.active()
This method returns
true
if SpaceCadet is enabled andfalse
if SpaceCadet is disabled. This is useful for interfacing with other plugins or macros, especially where SpaceCadet functionality isn't always desired.
.enableWithoutDelay()
This method enables the SpaceCadet plugin in "no-delay" mode. In this mode, SpaceCadet immediately sends the primary (modifier) value of the SpaceCadet key when it is pressed. If it is then released before timing out, it sends the alternate "tap" value, replacing the modifier.
Key_SpaceCadetEnable
This provides a key for placing on a keymap for enabling the SpaceCadet behavior. This is only triggered on initial press, and does not trigger again if held down or when the key is released.
Key_SpaceCadetDisable
This provides a key for placing on a keymap for disabling the SpaceCadet behavior. This is only triggered on initial press, and does not trigger again if held down or when the key is released.
