Edit YAML files for Ansible containing embedded Jinja2 templating. You will need to ensure that at least one of the following is installed: • The tree-sitter-yaml Tree-sitter parser (Emacs 29 and higher only). https://github.com/tree-sitter-grammars/tree-sitter-yaml • The yaml-mode Emacs package. https://github.com/yoshiki/yaml-mode If you have installed Emacs with your operating system’s package manager, it may have automatically installed the Tree-sitter parser for you, in which case you should be good to go.
