Layout/SpaceInsideHashLiteralBraces

Safe autocorrect: Yes :white_check_mark: The auto-correct a cop does is safe (equivalent) by design.

Description

Overview

Checks that braces used for hash literals have or don't have surrounding space depending on configuration.

Examples

EnforcedStyle: space (default)

# The `space` style enforces that hash literals have
# surrounding space.

# bad
h = {a: 1, b: 2}

# good
h = { a: 1, b: 2 }

EnforcedStyle: no_space

# The `no_space` style enforces that hash literals have
# no surrounding space.

# bad
h = { a: 1, b: 2 }

# good
h = {a: 1, b: 2}

EnforcedStyle: compact

# The `compact` style normally requires a space inside
# hash braces, with the exception that successive left
# braces or right braces are collapsed together in nested hashes.

# bad
h = { a: { b: 2 } }
foo = { { a: 1 } => { b: { c: 2 } } }

# good
h = { a: { b: 2 }}
foo = {{ a: 1 } => { b: { c: 2 }}}

EnforcedStyleForEmptyBraces: no_space (default)

# The `no_space` EnforcedStyleForEmptyBraces style enforces that
# empty hash braces do not contain spaces.

# bad
foo = { }
bar = {    }

# good
foo = {}
bar = {}

EnforcedStyleForEmptyBraces: space

# The `space` EnforcedStyleForEmptyBraces style enforces that
# empty hash braces contain space.

# bad
foo = {}

# good
foo = { }
foo = {  }
foo = {     }
