Minetest snippets mod

A way for admins to run and save lua snippets.

More documentation coming soon.

API

• snippets.register_snippet(name, <code or def>): Registers a snippet. def can be a table containing code (or func), and optionally owner. If persistent is specified, this snippet will remain registered across reboots.
• snippets.unregister_snippet(name): The opposite of snippets.register_snippet.
• snippets.registered_snippets: A table containing the above snippets.
• snippets.log(level, msg): For use inside snippets: Logs a message. level can be none, debug, info, warning, or error.
• snippets.register_on_log(function(snippet, level, msg)): Run when snippets.log is called. snippet is the name of the snippet. Newest functions are called first. If a callback returns true, any remaining functions are not called (including the built-in log function). Callbacks can check what player (if any) owns a snippet with snippets.registered_snippets[snippet].owner.
• snippets.log_levels: A table containing functions that run minetest.colorize on log levels (if applicable). Example: snippets.log_levels.error('Hello') → minetest.colorize('red', 'Hello')
• snippets.exec_as_player(player_or_name, code): Executes code (a string) inside an "anonymous snippet" owned by the player.
• snippets.exec(code): Executes code inside a generic snippet.
• snippets.run(name, ...): Executes a snippet.
