* fieldPairs() already handles variant objects fine. decided not to
go further along the way of identifying object variants by their
discriminants in tag URIs.
* variant objects are now supported just like normal objects.
* renamed setTagUriForType to setTagUri
* generated TagId is now const (can be used in case etc)
* Uses compile-time counter independent from tag library
* Fixed a parser bug that got confused when looking for an implicit
map key in a plain scalar that contains &, * or !
* Added OutputYamlVersion to PresentationOptions
* Renamed some symbols for consistency, fixes#6:
- yamlStartSequence -> yamlStartSeq
- yamlEndSequence -> yamlEndSeq
- yamlStartDocument -> yamlStartDoc
- yamlEndDocument -> yamlEndDoc
- yTagMap -> yTagMapping
* Improved code formatting at some places
* Fixed code documentation at some places
* Added generic objects to TODO list
* Removed obsolete parsing tests, these are superseeded
by yaml-dev-kit test suite integration
* Added PresentationOptions object; merged PresentationStyle,
indentationStep and NewLineStyle in it
* Updated signatures of relevant procs
* Implemented user-defined newline style in presenter
* Some typo fixes in code
* nim documentation now generates API doc with source links
* presenter now uses "" if a string starts with @ or `
* Removed some outdated stuff
* Added raises pragma to every proc in yaml.nim
* Properly encapsulate exceptions from YamlStreams
* Discovered a Nim compiler bug and added a workaround
* Added possibility to query line, column and line content from
YamlParser
* Updated rst documentation
* Actually call callback in fastparse if available
* Fixed parsing YAML version
* fastparse now used for everything
* private/[lexer|parser].nim gone
* Made fastparse use YamlParser object
* Got all tests working with fastparse
* Some more smaller changes to API
* Made TagLibrary a ref object
* Started writing fastparse.nim, a parser aimed to deliver
much faster speeds than the current implementation. It
currently is only able to parse block content
* Added YamlPresenter*Error exceptions
* Added raises pragma to present()
* catch exceptions from YamlStream and Stream in present() and
put them as cause into YamlPresenter*Error
* Added loadToJson() proc
* Give "~" the type hint yTypeNull
* Always output "null" for yTagNull/yTypeNull scalars when
presenter is in JSON mode
* Added YamlWarningCallback that may be used to capture
parser warnings
* Removed yamlWarning as event kind
* Replaced checks for well-formedness in presenter with asserts
* Added checks for JSON compatibility of YamlStream in presenter
* Added proper type hints for special float values in
serializer to be able to check for them in the presenter
* Yield tag of custom type serialization when using ytsRootOnly,
but don't yield tags of map keys or values
* Yield proper tag of Table[K, V] serialization if requested
* renamed dumper.nim to presenter.nim to conform to YAML spec
* Fixed a bug in the lexer where an error would be raised if
characters not allowed in tag shorthands are used in local tags
* Fixed processing of object tags for all kinds of root nodes in Parser
* Improved dumper to output a space after a local tag
* Renamed some enumeration types to conform better to the YAML spec
* Added secondaryPrefix to YamlTagLibrary
* Added possibility to control tag output style independently from
presentation style in serializer
* Created local tags for all types that are serialized and use them in
construction and serialization
* Better JSON serialization (map bool literals to true/false if
possible)
* Fixed a problem where the tag of block sequence would be
wrongly placed
* Always output "" when dumping empty strings
* Added helper functions to create YamlStreamEvents.
* Moved procs for YamlStreamEvents to private/events.nim
* renamed dump() to present()
* Added dump() and load() to yaml.serialization
