Features

Bugfixes

Other

  • Rewrite CLI using the derive API, see #225 (@sorairolake)

v0.14.0

Features

  • New --character-table option, with the ability to use codepage 437, see #194 and #195 (@sharifhsn)
  • New --character-table=ascii option for a ASCII-only character table, see #212 and #36 (@sharkdp)

Bugfixes

  • Show output when doing hexyl /dev/zero, see #211 (@sharifhsn)
  • Respect NO_COLOR environment variable, see #210 (@sharkdp)

v0.13.1

Bugfixes

  • Correctly handle discontinuous input (stdin), see #196 and #197 (@sharifhsn)

v0.13.0

Features

  • Support both little and big Endian dumps using --endianness={little,big}, see #189 and #104 (@RinHizakura)

Changes

  • Breaking: Changed the meaning of the short flag -C to be consistent with hexdump -C. Previously, this would hide the character panel, but now -C shows the character panel, in case it has been previously (e.g. in an alias) disabled with --no-characters, see #187 (@sharkdp)

hexyl as a library

  • New endianness method for PrinterBuilder

v0.12.0

Features

  • Only show one panel by default if the terminal width is not wide enough for two panels, see #182 (@sharkdp)
  • Respect the NO_COLOR environment variable, see #179 (@sharifhsn)

Bugfixes

  • Do not fail with an error if --panels=auto is used and the output is piped, see #184 (@sharkdp)

Changes

  • Breaking: For xxd-compatibility reasons, --group_bytes has been renamed to --group-size (with an --groupsize alias), see #121 (@sharkdp)

hexyl as a library

  • Breaking: num_group_bytes has been renamed to group_size.

v0.11.0

Features

  • Significantly improved performance, see #173 and #176 (@sharifhsn)
  • Added variable panels through the --panels and --terminal-width flags, see #13 and #164 (@sharifhsn)
  • Added new --group-bytes/-g option, see #104 and #170 (@RinHizakura)
  • Added new --base B option (where B can be binary, octal, decimal or hexadecimal), see #147 and #178 (@sharifhsn)
  • Show actual zero bytes as ⋄ in the character panel (previously: 0), in order not to confuse them with ASCII 0 bytes if colors are deactivated. Closes #166 (@sharkdp)

hexyl as a library

  • Breaking change: Printer::new is deprecated as a part of the public API. Alternatively, you can now construct a Printer using the PrinterBuilder builder API, see #168. (@sharifhsn)

Other

  • More tests for the squeezing feature, see #177 (@mkatychev)

Thank you

Special thanks go to @sharifhsn, not just for the new features, bugfixes and performance improvements. But also for many internal improvements of the code base and other maintenance tasks.

v0.10.0

Features

  • Added new --plain, --no-characters, and --no-position flags, see #154 (@mkatychev)
  • Allow hex numbers and units for --block-size argument, see #111 and #144 (@merkrafter)

Other

  • Added a man page, see #151 (@sorairolake)
  • Mention ability to specify length in hex, see #143 (@merkrafter)
  • --length and --bytes are now marked as conflicting command-line options, see #152 (@sorairolake)

v0.9.0

Changes

  • Breaking change (binary): setting the -o/--display-offset flag no longer overrides the value set by --skip #115. The first displayed address is now the sum of the two values - this matches the behaviour of xxd.

Features

  • Allow relative and negative byte offsets (e.g. hexyl --skip=-1block), see #99 (@ErichDonGubler)
  • Added -l as another alias for '-n/--length' (xxd compatibility), see #121 and #135 (@TheDoctor314)

Bugfixes

  • Argument --length silently takes precedence over --bytes, see #105
  • Print warning on empty content, see #107 and #108
  • Disallow block sizes of zero, see #110
  • Fix newline appearing in --version output, see #131 and #133 (@scimas)

Other

  • Better diagnostic messages, see #98 (@ErichDonGubler)

Packaging

  • hexyl is now available on snapstore, see #116 (@purveshpatel511)

v0.8.0

Features

  • A new --skip <N> / -s <N> option can be used to skip the first N bytes of the input, see #16, #88 (@Tarnadas, @MaxJohansen, @ErichDonGubler)
  • The --length/--bytes/--skip/--display-offset options can now take units for their value argument, for example: 
    hexyl /dev/random --length=1KiB
hexyl $(which hexyl) --skip=1MiB --length=10KiB
    Both decimal SI prefixes (kB, MB, …) as well as binary IEC prefixes (KiB, MiB, …) are supported. In addition, there is a new --block-size <SIZE> option that can be used to control the size of the block unit: 
    hexyl /dev/random --block-size=4kB --length=2block
    See: #44 (@ErichDonGubler and @aswild)

Other

  • Various improvements throughout the code base by @ErichDonGubler

Packaging

  • hexyl is now available on Void Linux, see #91 (@notramo)

v0.7.0

Bugfixes

  • hexyl can now be closed with Ctrl-C when reading input from STDIN, see #84

Changes

v0.6.0

Features

  • hexyl can now be used as a library, see #67 (@tommilligan)

  • Added a new -o/--display-offset option to add a certain offset to the reported file positions, see #57 (@tommilligan)

Bugfixes

  • Remove additional space on short input, see #69 (@nalshihabi)

Other

  • Performance improvements, see #73 and #66

v0.5.1

Bugfixes

  • Fixed build failure on OpenBSD 6.5, see #61

  • Added a new --border option with support for various styles (Unicode, ASCII, None), see #54 (@dmke)
  • The --length/-n argument can be passed as a hexadecimal number (hexyl -n 0xff /dev/urandom), see #45 (@Qyriad)
  • Added --bytes/-c as an alias for --length/-n, see #48 (@selfup)

Changes

  • Print header immediately before the first line, see #51 (@mziter)

v0.4.0
