README

A lightweight Drupal filter that converts simple inline footnote markers into numbered footnotes appended to the end of the content.

Overview

Footnote Writer provides a minimal syntax for adding footnotes directly inside text without dealing with HTML or manual numbering.

It is designed to:

• reduce friction while writing
• avoid manual footnote management
• integrate cleanly with Drupal’s text format system

This module does one thing:

• transform [fn: ...] into structured, numbered footnotes

Installation

composer require cms-alchemy/footnote-writer
drush en footnote_writer

On enabling, the filter is automatically enabled for:

• Basic HTML
• Full HTML

Usage

Write footnotes inline using:

[fn: This is a footnote.]

Multiple footnotes are supported:

This is a sentence.[fn: First note.]

Another sentence.[fn: Second note.] Output Behavior

The filter will:

replace each [fn: ...] with a numbered marker in the text collect all footnotes append them to the end of the content in order

Example (conceptual):

This is a sentence.¹

Another sentence.²

1. First note.
2. Second note.

Limitations

• Nested footnotes are not supported
• Complex structures inside footnotes may not render as expected
• Interaction with other filters depends on filter order
