Change {{folder_name}} and {{event_folder_name}} to return a dot instead of an empty string

[Taitava]

Currently, if a note is located in the vault's root folder, and a shell command like echo {{folder_name}} is executed, then the value of {{folder_name}} is an empty text.

I'm planning to change the value to be a dot . when the folder in question is the vault's root folder. This is a breaking change, unfortunately. (If the folder is not the vault's root, then nothing will change).

Examples of situations that are currently problematic:

Example situation	Current, problematic result	Better result after the change
When defining a file path where {{folder_name}} is just one part of it, e.g. echo "Content" > {{folder_name}}/NewNote.md	echo "Content" > /NewNote.md Creates a file to the file system root, outside of the Obsidian vault.	echo "Content" > ./NewNote.md Creates a file correctly in the current working directory, i.e. usually the vault's root folder.
When copying a directory, e.g. cp -r {{folder_name}} /absolute/path/for/new/folder/outside/of/the/vault	cp -r /absolute/path/for/new/folder/outside/of/the/vault The first argument to cp is omitted because it was empty.	cp -r . /absolute/path/for/new/folder/outside/of/the/vault The first argument is correctly . so it's not accidentally omitted.

Variables affected by the change

• {{folder_name}}
• {{event_folder_name}}

Variables that already give a dot . in similar situations

• {{folder_path:relative}}
• {{event_folder_path:relative}}
• {{new_note_folder_name}}
• {{new_note_folder_path}}

As there are already variables that give a dot . for the root folder, this change will streamline the behavior.
