ChangeLog

[Unreleased][unreleased]

Changed/Fixed

Added

Thanks

0.10.0

Changed/Fixed

  • Refactor code
  • Upgrade to nom 7
  • Reduce nom dependencies and features (remove bitvec)
  • Fix parsing of String with generic errors enabled (#32)

0.9.1

Changed/Fixed

  • Special case derive functions should be public (#27)
  • Fixed missing extra_args in parsing function decls (#29)

Added

  • Enable array fields (#26)

Thanks

  • @dbcfd for fixing public attribute on special-case functions
  • @katyo for fixing missing extra_args
  • @hammypants for arrays (#26)

0.9.0

Changed/Fixed

Added

  • Add Into attribute to convert output/error types
  • Generate implementation of Parse trait when possible (closes #21)

The code now generates 3 functions instead of one (parse):

  • parse_be: parse object as big-endian
  • parse_le: parse object as little-endian
  • parse: default function, wraps a call to parse_be

If the endianness of the struct is fixed, then all 3 functions are equivalent.

Thanks

0.8.0

Refactor crate:

  • Split crate in two (nom-derive and nom-derive-impl) so it can export public items, in particular the Parse trait
  • Provide implementation of Parse for primitive types, including primitive arrays (closes #4). Also provide example of newtype pattern to specify different implementations (#16)
  • Refactor argument parsing and code generation. The AST now include all items, and does not handle most attributes as special, and generate code from top to bottom. This means that
    • attributes are now all handled the same way for deriving struct and enum
    • order of attributes is now important
    • it is possible to specify that a field should be first parse then ignored (#18), or the parse function that will be used with Count (#9)
    • endianness is now determined by first looking a field attribute, then object endianness.
    • The NomBE and NomLE custom derive attributes have been added, and allow specifying global endianness using imports (for ex use nom_derive::NomLE as Nom) (#14)
  • Add support for generic type parameters and better support for lifetimes and where clauses
  • Add GenericErrors attribute, to generate a function signature with generic error type (#19)
  • Add Complete attribute for top-level (#17)

Except for the order of attributes, there should be no breaking change.

0.7.2

  • Add LengthCount attribute (#15)
  • Add f32 and f64 as native types (#16)
  • Rewrite error handling to raise compile errors (instead of panic)

0.7.1

  • Fix build for syn 1.0.58 (#11)

0.7.0

  • Upgrade to nom 6

0.6.3

  • Add support for guards in Selector Patterns (#5)
  • Add limited support for Unit fields in enum (#6)
  • Make parse method public for enums too (#7)

0.6.2

  • Add ExtraArgs support for structs (top-level only)
  • Allow dynamic configuration of endianness (SetEndian attribute)
  • Add support for u128/i128 (#3)

0.6.1

  • Add Tag attribute
  • Fix type verification with Cond when using multiple attributes

0.6.0

  • Switch to nom parsing functions, do not generate macros
  • Use qualified paths, caller do not have to import nom macros
  • Move all attributes under the 'nom' namespace
  • Add many attributes (LittleEndian, BigEndian, Map, Debug, Value, Take, AlignAfter/AlignBefore, SkipAfter/SkipBefore, ErrorIf, etc.)
  • Deprecate the NomDeriveDebug derive (replaced by DebugDerive attribute)
  • Improve documentation, add many examples
  • Rewrite attribute parser, now accepting a more flexible syntax

0.5.0

  • Upgrade to nom 5.0
  • The parse method is now public
  • Upgrade dependencies (syn, quote, proc-macro2)

0.4.0

  • Add support for Enum parser generator
    • Enums require a selector to choose the variant
    • Fieldless enums (list of constants) are handled as a special case
  • Add NomDeriveDebug attribute to display generated parser on stderr during build

0.3.0

  • Move crate to rust-bakery github project
  • Add Count attribute
