input-remapper comes with an optional custom macro language with support for cross-device variables, conditions and named parameters.
Syntax errors are shown in the UI on save. Each key
function adds a short delay of 10ms
between key-down, key-up and at the end. See usage.md
for more info.
Macros are written into the same text field, that would usually contain the output symbol.
Bear in mind that anti-cheat software might detect macros in games.
Acts like a pressed key. All names that are available in regular mappings can be used here.
key(symbol: str)Examples:
key(symbol=KEY_A) key(b).key(space)
Inject the press/down/1 and release/up/0 events individually with those macros.
key_down(symbol: str) key_up(symbol: str)Examples:
key_down(KEY_A) key_up(KEY_B)
Waits in milliseconds before continuing the macro. If the max_time argument is provided, it will randomize the time between time and max_time.
wait(time: int, max_time: int | None)Examples:
wait(time=100) wait(500) wait(10, 1000)
Repeats the execution of the second parameter a few times
repeat(repeats: int, macro: Macro)Examples:
repeat(1, key(KEY_A)) repeat(repeats=2, key(space))
Holds a modifier while executing the second parameter
modify(modifier: str, macro: Macro)Examples:
modify(Control_L, key(a).key(x))
If an input is held down long enough, then it turns into a modifier for all keys that came and come afterwards.
You can use this to create home row mods for example.
Behaves similar to the Mod-Tap feature of QMK.
mod_tap( default: str, modifier: str, tapping_term: int )Examples:
mod_tap(a, Shift_L) mod_tap(s, Control_L, 300)
Holds down all the provided symbols like a combination, and releases them when the actual key on your keyboard is released.
An arbitrary number of symbols can be provided.
When provided with a single key, it will behave just like a regular keyboard key.
hold_keys(*symbols: str)Examples:
hold_keys(KEY_B) hold_keys(KEY_LEFTCTRL, KEY_A) hold_keys(Control_L, Alt_L, Delete) set(foo, KEY_A).hold_keys($foo)
Runs the child macro repeatedly as long as the input is pressed.
hold(macro: Macro)Examples:
hold(key(space))
Moves the mouse cursor
If the fractional
acceleration
value is provided then the cursor will accelerate from zero to a maximum speed ofspeed
.mouse( direction: up | down | left | right, speed: int, acceleration: int | float )Examples:
mouse(up, 1) mouse(left, 2) mouse(down, 10, 0.05)
Moves the mouse cursor in both x and y direction.
If the fractional
acceleration
value is provided then the cursor will accelerate from zero to the maximum specified x and y speeds.mouse( x: int | float, y: int | float, acceleration: int | float )Examples:
mouse_xy(x=10, y=20) mouse_xy(-5, -1, 0.01) mouse_xy(x=10, acceleration=0.05)
Injects scroll wheel events
wheel( direction: up | down | left | right, speed: int )Examples:
mouse(up, 10) mouse(left, 20)
Writes an event. Examples for
type
,code
andvalue
can be found via thesudo evtest
command. Also check out input-event-codes.h.EV_KEY
for keys,EV_REL
for mouse movements,EV_ABS
for gamepad events among others.event( type: str | int, code: str | int, value: int )Examples:
event(EV_KEY, KEY_A, 1) event(EV_REL, REL_X, -10) event(2, 8, 1)
Set a variable to a value. This variable and its value is available in all injection processes.
Variables can be used in function arguments by adding a
$
in front of their name:repeat($foo, key(KEY_A))
Their values are available for other injections/devices as well, so you can make them interact with each other. In other words, using
set
on a keyboard andif_eq
with the previously used variable name on a mouse will work.set(variable: str, value: str | int)Examples:
set(foo, 1) set(foo, "qux")
Adds a number fo a variable.
add(variable: str, value: int)Examples:
set(a, 1).add(a, 2).if_eq($a, 3, key(x), key(y))
Compare two values and run different macros depending on the outcome.
if_eq( value_1: str | int, value_2: str | int, then: Macro | None, else: Macro | None )Examples:
set(a, 1).if_eq($a, 1, key(KEY_A), key(KEY_B)) set(a, 1).set(b, 1).if_eq($a, $b, else=key(KEY_B).key(KEY_C)) set(a, "foo").if_eq("foo", $a, key(KEY_A)) set(a, 1).if_eq($a, 1, None, key(KEY_B))
Run the first macro if your capslock is on, otherwise the second.
if_capslock( then: Macro | None, else: Macro | None )Examples:
if_capslock( then=hold_keys(KEY_3), else=hold_keys(KEY_4) )
Run the first macro if your numlock is on, otherwise the second.
if_numlock( then: Macro | None, else: Macro | None )Examples:
if_numlock(hold_keys(KEY_3), hold_keys(KEY_4))
If the key is tapped quickly, run the
then
macro, otherwise the second. The third param is the optional time in milliseconds and defaults to 300msif_tap( then: Macro | None, else: Macro | None, timeout: int )Examples:
if_tap(key(KEY_A), key(KEY_B), timeout=500) if_tap(then=key(KEY_A), else=key(KEY_B))
If the key that is mapped to the macro is pressed and released, run the
then
macro.If another key is pressed while the triggering key is held down, run the
else
macro.If a timeout number is provided, the macro will run
else
if no event arrives for more than the configured number in milliseconds.if_single( then: Macro | None, else: Macro | None, timeout: int | None )Examples:
if_single(key(KEY_A), key(KEY_B)) if_single(None, key(KEY_B)) if_single(then=key(KEY_A), else=key(KEY_B)) if_single(key(KEY_A), key(KEY_B), timeout=1000)
Run all provided macros in parallel.
parallel(*macros: Macro)Examples:
parallel( mouse(up, 10), hold_keys(a), wheel(down, 10) )
Multiple functions are chained using .
.
Unlike other programming languages, qux(bar())
would not run bar
and then
qux
. Instead, cux
can decide to run bar
during runtime depending on various
other factors. Like repeat
is running its parameter multiple times.
Whitespaces, newlines and tabs don't have any meaning and are removed when the macro gets compiled, unless you wrap your strings in "quotes".
Similar to python, arguments can be either positional or keyword arguments.
key(symbol=KEY_A)
is the same as key(KEY_A)
.
Using $
resolves a variable during runtime. For example set(a, $1)
and
if_eq($a, 1, key(KEY_A), key(KEY_B))
.
Comments can be written with '#', like key(KEY_A) # write an "a"
