[Feature]: add `if` tag for conditions

[dromse]

What kind of feature do you want?

Add tag if for showing task by specific conditions defined in scripts.

Draft example

First, you need to set path to directory where you will be store condition scripts. For example Conditions in the root of vault.

You can write script tuesday.js to show task only on tuesdays.

// Conditions/tuesday.js
const date = new Date();
const dayOfWeek = date.toLocaleString("en-US", { weekday: "long" });

function showOnTuesday() {
  if (dayOfWeek === "Tuesday") {
    return true;
  }

  return false;
}

export default showOnTuesday

Remark: Your function must return boolean value.

And then you can use your condition:

- [ ] do a very important task #if/tuesday

And then if task is not done, it will appear in UI on every tuesday.

You can define different logic like show task on location, weather, time, device conditions etc. It's all about your imagination and JavaScript API capabilities.

Impact

Impact for users

Pros:

• Users can define their personal wanted conditions
• Users don't need to wait on new functionality for task conditions

Cons:

• Risk of using not verified scripts (How to avoid: write your own scripts or use verified ones)
• Learning JavaScript for creating scripts (How to avoid: developers need to create list for verified scripts for common usage)

Impact for development

Pros:

• Delegate part of work on plugin to users personal scripts
• Decrease unnecessary code growing

Cons:

• Increases risk of bugs because of new functionality (How to avoid: cover new functionality by tests)
