binary 1.2.1

Utilities for accessing binary data and bit manipulation in Dart and Flutter

CHANGELOG

1.2.1

• Fixed a bug where BitPatternBuilder.parse('00AA_AABB') incorrectly threw a FormatException assuming that _ deliniated the end of the A variable segment and the subsequent A was a new segment (which is invalid). It now correctly parses the above as just two variable segments (AAAA, BB).

1.2.0

• Added BitPatternBuilder.parse, a simplified-format for building BitPattern from a string of alpha-numeric characters, where 0 and 1 are pre-defined (static) flags for matching, and charaters are variable segments:

  // Create a BitPattern (Data Structures).
  final $01V = BitPatternBuilder([
    BitPart(0),
    BitPart(1),
    BitPart.v(1, 'A'),
  ]).build();
  
  // Create a BitPattern (Parse a String).
  final $01Vs = BitPatternBuilder.parse('01A').build();
  print($01V == $01Vs); // true
  

• Fixed a bug where it was not possible to capture variables that were >8-bit.

1.1.0

• Added BitPatternBuilder, BitPattern, BitPart: a new API in order to build bit-based patterns and match against arbitrary sets of bits, optionally extracting variable names. This API is intended to make it easier to build apps and packages around implementing emulators and other decoders.

1.0.0

A large update to bring into line for Dart 2, as well take advantage of newer langauge features like extension methods over top-level methods. As a result, the new API is not compatible with previous versions, but migration should be trivial.

0.1.3

• Added arithmeticShiftRight

0.1.2

• Moved into a standalone repository (outside of gba.dart).
• Added signExtend as a method to Integral.
• Added areSet.
• Added msb.

0.1.1

• Added signExtend

0.1.0

• Fixed a bug where int128 and uint128 only had a length of 64.

0.0.4

• Updated the documentation and README.

0.0.3

• Added isZero.

0.0.2

• Added isNegative, hasCarryBit, doesAddOverflow, doesSubOverflow, mask.
• Added parseBits.

0.0.1

• Add top-level isSet and isClear, Integral#isSet, Integral#isClear.
• Add checked-mode range checks to bitChunk and bitRange.
• Fix a bug in the implementation of bitChunk and bitRange.
• Added a top-level fromBits and Integral#fromBits

0.0.0

• Initial commit, feedback welcome!
