Obsidian Templater Script to Generate Folder Links

folder_links.js

// This function will generate links to every file in the same folder as this one
// use <%tp.user.folder_links(tp.file.path(), tp.file.title)%> to generate the list.

// The main use of this is if the notes are organized "Wiki style", with a file in
// each folder that matches the folder name, i.e.

// notes/
// ├─ notes.md
// ├─ stickynotes/
// │  ├─ stickynotes.md
// │  ├─ dec-21-2020.md
// ├─ school/
// │  ├─ school.md
// │  ├─ chemistry/
// │  │  ├─ chemistry.md
