Recommended Text Editors
We highly recommend to use a decent editor software to manage Kometa's .yml files.
Standard text editors (such as Notepad and TextEdit) often save text in a rich-text format which can result in text formatted in a way that Kometa cannot read. But not only that, they also make it very hard to visually distinguish the formatting, such as indentation.
Kometa requires indents to always be multiples of 2 spaces, and not TAB stops. If you have one space too much, or too few, it is very hard to notice that with a editor like Notepad.
An editor that is more focused on editing code instead of text will automatically detect the .YML fileformat and adjust things to make it easier to work. They can also try to detect possible errors even before you actually run the .yml in Kometa.
This can save a lot of time and headaches.
Preferred:
Visual Studio Code (Windows/Mac/Linux, Opensource & Free) Website
Additionally, install the indent-rainbow by oderwat extension and the YAML by Red Hat extension and leverage our schema.json file by adding this to the top of your config.yml file: # yaml-language-server: $schema=https://raw.githubusercontent.com/Kometa-Team/Kometa/nightly/json-schema/config-schema.json
Other options:
Notepad++ (Windows only, Opensource & Free)
Website
Sublime Text (Windows/Mac/Linux, Paid)
