Elixir v1.4.5 Inspect.Opts View Source
Defines the Inspect.Opts used by the Inspect protocol.
The following fields are available:
:structs
- whenfalse
, structs are not formatted by the inspect protocol, they are instead printed as maps, defaults totrue
.:binaries
- when:as_strings
all binaries will be printed as strings, non-printable bytes will be escaped.When
:as_binaries
all binaries will be printed in bit syntax.When the default
:infer
, the binary will be printed as a string if it is printable, otherwise in bit syntax.:charlists
- when:as_charlists
all lists will be printed as char lists, non-printable elements will be escaped.When
:as_lists
all lists will be printed as lists.When the default
:infer
, the list will be printed as a charlist if it is printable, otherwise as list.:limit
- limits the number of items that are printed for tuples, bitstrings, and lists, does not apply to strings nor charlists, defaults to 50.:pretty
- if set totrue
enables pretty printing, defaults tofalse
.:width
- defaults to 80 characters, used when pretty istrue
or when printing to IO devices. Set to 0 to force each item to be printed on its own line.:base
- prints integers as:binary
,:octal
,:decimal
, or:hex
, defaults to:decimal
. When inspecting binaries any:base
other than:decimal
impliesbinaries: :as_binaries
.:safe
- whenfalse
, failures while inspecting structs will be raised as errors instead of being wrapped in theInspect.Error
exception. This is useful when debugging failures and crashes for custom inspect implementations:syntax_colors
- when set to a keyword list of colors the output will be colorized. The keys are types and the values are the colors to use for each type. e.g.[number: :red, atom: :blue]
. Types can include:number
,:atom
,regex
,:tuple
,:map
,:list
, and:reset
. Colors can be anyIO.ANSI.ansidata/0
as accepted byIO.ANSI.format/1
.
