PRED can either be a regexp string or a major mode symbol. PLIST may contain

these properties:

Provides a secondary predicate. This function takes no arguments and is

executed from within the target buffer. If it returns nil, this rule will be

skipped over.

:trigger
|

The yasnippet trigger keyword used to trigger the target snippet. If
|

omitted, `+file-templates-default-trigger' is used.
|

:mode SYMBOL
|
||||
What mode to get the yasnippet snippet from. If omitted, either PRED (if
|
||||
it's a major-mode symbol) or the mode of the buffer is used.
|

:project BOOL
|

If non-nil, ignore this template if this buffer isn't in a project.

:ignore BOOL

If non-nil, don't expand any template for this file and don't test any other
