Struct lib_ruby_parser::nodes::XHeredoc [−][src]
#[repr(C)]pub struct XHeredoc { pub parts: Vec<Node>, pub heredoc_body_l: Loc, pub heredoc_end_l: Loc, pub expression_l: Loc, }
Expand description
Represents a executable here-document literal (both with and without interpolation)
It’s similar to Xstr
in terms of abstract syntax tree, but has different source maps.
Fields
parts: Vec<Node>
A list of string parts (static literals and interpolated expressions)
heredoc_body_l: Loc
Location of the executable here-document body
<<-`HERE`\n a\n #{42}\nHERE
~~~~~~~~~~~~~~~
heredoc_end_l: Loc
Location of the executable here-document end
<<-`HERE`\n a\n #{42}\nHERE
~~~~
expression_l: Loc
Location of the executable here-document identifier
<<-`HERE`\n a\n #{42}\nHERE
~~~~~~~
Note: This is the only node (with Heredoc
) that has expression_l
smaller that all other sub-locations merged.
The reason for that is that it’s possible to add more code after here-document ID:
<<-`HERE` + "rest"
content
HERE
