Functions

cmd(str)

Run a command and return the exit code. This function is intended to be run interactively

hex(value)

Inspect a value with all integers printed out in hex. This is useful for one-off hex conversions. If you’re doing a lot of work that requires hexadecimal output, you should consider running

cmd(str)

cmd(String.t() | charlist()) :: integer()

Run a command and return the exit code. This function is intended to be run interactively.

hex(value)

hex(integer()) :: String.t()

Inspect a value with all integers printed out in hex. This is useful for one-off hex conversions. If you’re doing a lot of work that requires hexadecimal output, you should consider running:

IEx.configure(inspect: [base: :hex])

The drawback of doing the above is that strings print out as hex binaries.
