NimYAML/CHANGELOG.md

0.9.0

Features:

• Better DOM API:
  • yMapping is now a Table
  • field names have changed to imitate those of Nim's json API
  • Better getter and setter procs
• Added ability to resolve non-specific tags in presenter.transform

Bugfixes:

• Fixed parsing floating point literals (#30)
• Fixed a bug with variant records (#31)
• Empty documents now always contain an empty scalar

0.8.0

Features:

• NimYAML now has a global tag URI prefix for Nim types, tag:nimyaml.org,2016:. This prefix is denoted by the custom tag handle !n!.
• Support arbitrary tag handles.
• Added ability to mark object and tuple fields as transient.
• Added ability to set a default value for object fields.
• Added ability to ignore key-value pairs in the input when loading object values.
• Support !!timestamp by parsing it to Time from module times.

Bugfixes:

• Fixed a bug concerning duplicate TagIds for different tags in the serializationTagLibrary
• Convert commas in tag URIs to semicolons when using a tag URI as generic parameter to another one, because commas after the tag handle are interpreted as flow separators.

0.7.0

Features:

• Better handling of internal error messages
• Refactoring of low-level API:
  • No more usage of first-class iterators (not supported for JS target)
  • Added ability to directly use strings as input without stdlib's streams (which are not available for JS)
• Added ability to parse octal and hexadecimal numbers
• Restructuring of API: now available as submodules of yaml. For backwards compatibility, it is still possible to import yaml, which will import all submodules
• Check for missing, duplicate and unknown fields when deserializing tuples and objects

Bugfixes:

• Fixed double quotes inside plain scalar (#25)
• Return correct line content for errors if possible (#23)
• Some smaller lexer/parser fixes

0.6.3

Bugfixes:

• Can load floats from integer literals (without decimal point) (#22)

0.6.2

Bugfixes:

• Fixed problem when serializing a type that overloads the == operator (#19)
• Fixed type hints for floats (0 digit was not processed properly) (#21)

0.6.1

Bugfixes:

• Fixed deserialization of floats (#17)
• Handle IndexError from queues properly

0.6.0

Features:

• Properly support variant object types
• First version that works with a released Nim version (0.14.0)

Bugfixes:

• Fixed a crash in presenter when outputting JSON or canonical YAML
• Raise an exception when trying to output multiple documents in JSON style

0.5.1

Bugfixes:

• Fixed a problem that was introduced by a change in Nim devel

0.5.0

Features:

• Support variant object types (experimental)
• Added ability to use variant object types to process heterogeneous data
• Support set type
• Support array type
• Support int, uint and float types (previously, the precision must be specified)
• Check for duplicate tag URIs at compile time
• Renamed setTagUriForType to setTagUri

Bugfixes:

• None, but fastparse.nim has seen heavy refactoring

0.4.0

Features:

• Added option to output YAML 1.1
• Added benchmark for processing YAML input
• Serialization for OrderedMap
• Use !nim:field for object field names (#12)

Bugfixes:

• Code refactoring (#9, #10, #11, #13)
• Some small improvements parsing and presenting

0.3.0

Features:

• Renamed some symbols to improve consistency (#6):
  • yamlStartSequence -> yamlStartSeq
  • yamlEndSequence -> yamlEndSeq
  • yamlStartDocument -> yamlStartDoc
  • yamlEndDocument -> yamlEndDoc
  • yTagMap -> yTagMapping
• Introduced PresentationOptions:
  • Let user specify newline style
  • Merged old presentation options indentationStep and presentationStyle into it
• Use YAML test suite from yaml-dev-kit to test parser.

Bugfixes:

• Fixed various parser bugs discovered with YAML test suite:
  • Block scalar as root node no longer leads to a parser error
  • Fixed a bug that caused incorrect handling of comments after plain scalars
  • Fixed bugs with newline handling of block scalars
  • Fixed a bug related to block sequence indentation
  • Skip content in tag and anchor names and single-quoted scalars when scanning for possible implicit map key
  • Properly handle more indented lines in folded block scalars
  • Fixed a problem with handling ':' after whitespace
  • Fixed indentation handling after block scalar

0.2.0

Features:

• Added DOM API
• Output block scalars in presenter if scalar is long and block scalar output is feasible. Else, use multiple lines for long scalars in double quotes.

Bugfixes:

• Improved parser (#1, #3, #5)
• Made parser correctly handle block sequences that have the same indentation as their parent node (#2)
• Fixed problems with outputting double quoted strings (#4)

0.1.0

• Initial release
