hexdump.rb - 1.0.0 Latest Release

Published by postmodern 9 months ago

  • Added the ability to hexdump typed data. Available type:s are :
    • :char - signed 8bit ASCII character
    • :uchar - unsigned 8bit ASCII character
    • :int8 - signed 8bit integer
    • :uin8 / :byte - unsigned 8bit integer (default)
    • :int16 / :short - signed 16bit integer
    • :int16_le / :short_le - signed 16bit integer (little endian)
    • :int16_be / :short_be - signed 16bit integer (big endian)
    • :int16_ne / :short_ne - signed 16bit integer (network endian)
    • :uint16 / :ushort - unsigned 16bit integer
    • :uint16_le / :ushort_le - unsigned 16bit integer (little endian)
    • :uint16_be / :ushort_be - unsigned 16bit integer (big endian)
    • :uint16_ne / :ushort_ne - unsigned 16bit integer (network endian)
    • :int32 / :int / :long - signed 32bit integer
    • :int32_le / :int_le / :long_le - signed 32bit integer (little endian)
    • :int32_be / :int_be / :long_be - signed 32bit integer (big endian)
    • :int32_ne / :int_ne / :long_ne - signed 32bit integer (network endian)
    • :uint32 / :uint / :ulong - unsigned 32bit integer
    • :uint32_le / :uint_le / :ulong_le - unsigned 32bit integer (little endian)
    • :uint32_be / :uint_be / :ulong_be - unsigned 32bit integer (big endian)
    • :uint32_ne / :uint_ne / :ulong_ne - unsigned 32bit integer (network endian)
    • :int64 / :long_long - signed 64bit integer
    • :int64_le / :long_long_le - signed 64bit integer (little endian)
    • :int64_be / :long_long_be - signed 64bit integer (big endian)
    • :int64_ne / :long_long_ne - signed 64bit integer (network endian)
    • :uint64 / :ulong_long - unsigned 64bit integer
    • :uint64_le / :ulong_long_le - unsigned 64bit integer (little endian)
    • :uint64_be / :ulong_long_be - unsigned 64bit integer (big endian)
    • :uint64_ne / ulong_long_ne - unsigned 64bit integer (network endian)
    • :float - single precision 32bit floating-point number
    • :float_le - single precision 32bit floating-point number (little endian)
    • :float_be - single precision 32bit floating-point number (big endian)
    • :float_ne - single precision 32bit floating-point number (network endian)
    • :double - double precision 64bit floating-point number
    • :double_le - double precision 64bit floating-point number (little endian)
    • :double_be - double precision 64bit floating-point number (big endian)
    • :double_ne - double precision 64bit floating-point number (network endian)
  • Added support for optionally skipping N bytes or reading at most N bytes of
    data (ex: offset: 10 and length: 100).
  • Added support for optional zero-padding of the data so it aligns with the type
    size (ex: zero_pad: true).
  • Added support for displaying the index in a separate numeric base than the
    numeric columns (ex: index_base: 10, base: 2). Defaults to base 16.
  • Added support for omitting repeating rows with a * (ex: repeating: true or
    repeating: false to disable).
  • Added support for grouping columns together like GNU hexdump -C (ex:
    group_columns: 4).
  • Added support for grouping characters together (ex: group_chars: 4).
  • Added support for grouping characters together to align with the type's size
    (ex: group_chars: :type).
  • Added support for displaying UTF-8 characters or other character encodings.
  • Added support for disabling the characters column entirely
    (ex: chars_column: false).
  • Added support for ANSI styling and highlighting (ex: style: {...} and
    highlights: {...}).
  • Added Hexdump::ModuleMethods to provide a top-level
    Hexdump::ModuleMethods#hexdump hexdump method.
    • Include Hexdump::ModuleMethods into Kernel by default.
  • Added preliminary truffleruby support.
  • hexdump methods now accept a block for configuring the hexdump instance.
  • Renamed Hexdump::Dumper to Hexdump::Hexdump.
  • Renamed the :width option to :columns.
hexdump.rb - 1.0.1

Published by postmodern 9 months ago

  • Switched to using require_relative to improve load-times.
  • Correctly alias :long/:ulong to :int32/:uint32.
  • Disable ANSI styling in Hexdump#hexdump if the output is not a TTY.
  • Removed the old hexdump/extensions file in favor of hexdump/core_ext.
