Detailed Description

parse a read-only (immutable) YAML source buffer.

This is achieved by first copying the contents of the buffer to the tree's arena, and then calling parse_in_arena() . All the resulting scalars will be filtered in the arena. These overloads accept an existing parser object, and provide the opportunity to use special parser options.

See also

ParserOptions

Note

These freestanding functions use a temporary parser object, and are convenience functions to easily parse YAML without the need to instantiate a separate parser. Note that some properties (notably node locations in the original source code) are only available through the parser class. If you need access to any of these properties, use the appropriate overload from Parse in arena with existing parser

Warning

overloads receiving a substr YAML buffer are intentionally left undefined, such that calling parse_in_arena() with a substr will cause a linker error. This is to prevent an accidental copy of the source buffer to the tree's arena, because substr (which is mutable) is implicitly convertible to csubstr (which is immutable). If you really intend to parse a mutable buffer in the tree's arena, convert it first to immutable by assigning the substr to a csubstr prior to calling parse_in_arena(). This is not needed for parse_in_place() because csubstr is not implicitly convertible to substr. To be clear:

 {c++}
substr mutable_buffer = ...;
parser.parse_in_arena(mutable_buffer); // linker error
 
csubstr immutable_buffer = ...;
parser.parse_in_arena(immutable_buffer); // ok
