Support invert Property for Boolean Type Fields in contentTypes configuration

[chriskyfung]

I would like to suggest adding support for the invert property for boolean type fields in the frontMatter.taxonomy.contentTypes configuration. This feature would allow users to invert the logic of boolean fields, making it easier to handle scenarios where the absence of a field should be interpreted as false.

Use Case

A common scenario where this feature would be useful is when a user wants to exclude a page from the sitemap. In Jekyll, this can be achieved using the jekyll-sitemap plugin by adding sitemap: false to the page front matter. Here is an example:

---
title: Exclude from Sitemap
sitemap: false
---

# The page should be excluded from the sitemap

Current Issue

Currently, when defining a boolean field in the frontMatter.taxonomy.contentTypes configuration as follows:

{
  "title": "Sitemap",
  "name": "sitemap",
  "type": "boolean"
}

The behaviors in the editor panel:

• Toggling on the Sitemap field results in sitemap: true in the front matter.
• Toggling off the Sitemap field removes the sitemap field from the front matter.

These behaviors do not allow for the explicit setting of sitemap: false, which is necessary to exclude a page from the sitemap.

Proposed Solution

By adding support for the invert property, users could define the boolean field as follows:

{
  "title": "Sitemap",
  "name": "sitemap",
  "type": "boolean",
  "invert": true
}

With this configuration:

• Toggling on the Sitemap field would result in sitemap: false in the front matter.
• Toggling off the Sitemap field would remove the sitemap field from the front matter.

This would allow users to explicitly set sitemap: false to exclude a page from the sitemap, aligning with the behavior of the jekyll-sitemap plugin.

Benefits

• Provides greater flexibility in handling boolean fields.
• Aligns with common practices in other static site generators like Jekyll.
• Enhances the user experience by allowing for more explicit control over front matter fields.

Supporting the invert property for boolean type fields in the frontMatter.taxonomy.contentTypes configuration would be a valuable addition, enabling users to better manage their content and configurations. I hope you consider this feature request for future updates.
