Changed the name to avoid conflict with https://hex.pm

Hex Formatter

Returns a hex encoded binary from a list, binary or integer.

iex> Hexfmt.encode("12345678")
"3132333435363738"

iex> Hexfmt.encode(12345678)
"BC614E"

Returns a decoded binary from a hex string

iex> Hexfmt.decode("3132333435363738")
"12345678"

Returns a hex string visual representation of a given list or binary. No need to insert leading '0', just to see the contents of a list.

iex> Hexfmt.hexify('ABcd')
"[0x41, 0x42, 0x63, 0x64]"

iex> Hexfmt.hexify("ABcd")
"<<0x41, 0x42, 0x63, 0x64>>"

Returns a decimal string visual representation of a given list or binary. No need to insert leading '0', just to see the contents of a list.

iex> Hexfmt.decify('ABcd')
"[65, 66, 99, 100]"

iex> Hexfmt.decify("ABcd")
"<<65, 66, 99, 100>>"

~h Sigil

iex> import HexSigil
nil

takes a String containing hex characters [0..9, A..F], and converts it into an Elixir binary of 8-bit hex numbers

iex> ~h{12345678}
<<18, 52, 86, 120>>

takes a String in form of comma separated values, and converts it into an String containing hex characters [0..9, A..F]

iex> ~h{18, 52, 86, 120}x
"12345678"
