# Measures

## NUOL measure

A NUOL measure is a disabled measure which when updated executes a bang. 

```
[Rainmeter]
OnRefreshAction=[!Delay 20][!EnableMeasureGroup NUOL]
; having a delay prevents the measures from updating & executing when the module is first loaded

[ACTIONHELLOWORLD]
Measure=Calc        ; Any unreactive measure type is fine
OnUpdateAction=[!Log "HelloWorld!"]     ; can be any action
Group=NUOL
Disabled=1
```

And to call this bang, you can simply update the measure with \
`!UpdateMeasure ACTIONHELLOWORLD` 

But why not just call a variable with a bang value? That will work... but only when called in the currentconfig. Using a NUOL measure you can call the bangs from a different config with\
`!UpdateMeasure ACTIONHELLOWORLD "MainConfigName\Main"`

## mToggle measure

{% hint style="warning" %}
mToggle measures are used in most hotkey modules toggle\
It is not recommended to use mToggle anymore, instead, use lua to achieve better results
{% endhint %}

A mToggle measure is a measure which when called toggles and execute actions.\
We'll be using NUOL measures to support calling functions from different configs.

```
[mToggle]
Measure=Calc
Formula=1 - mToggle            ; every time the measure updates, the value toggles
IfCondition=mToggle = 0
IfTrueAction=[!UpdateMeasure ACTIONLOAD]
IfFalseAction=[!UpdateMeasure ACTIONUNLOAD]
```

{% hint style="info" %}
The default value of mToggle is always 1, and you cannot have it default 0. 
{% endhint %}

This mToggle works, but you are unable to set it to either value with an action. Therefore, we'll be needing another measure to set mToggle's value: **mToggleSet**

```
[mToggleSet]
Measure=Calc
Formula=mToggle
IfCondition=mToggle = 0                ; This allows the measure to always set mToggle's value to 1
iftrueaction=[!UpdateMeasure mToggle]
ifconditionmode=1
Group=NUOL
Disabled=1
```
