Prefer double-quoted strings unless you need single quotes to avoid extra backslashes for escaping. Open
require 'aws-sdk-ses'

- Exclude checks
Checks if uses of quotes match the configured preference.
Example: EnforcedStyle: single_quotes (default)
# bad
"No special symbols"
"No string interpolation"
"Just text"
# good
'No special symbols'
'No string interpolation'
'Just text'
"Wait! What's #{this}!"
Example: EnforcedStyle: double_quotes
# bad
'Just some text'
'No special chars or interpolation'
# good
"Just some text"
"No special chars or interpolation"
"Every string in #{project} uses double_quotes"
Closing method call brace must be on the line after the last argument when opening brace is on a separate line from the first argument. Open
AwsCredentials.secret_access_key))
- Read upRead up
- Exclude checks
This cop checks that the closing brace in a method call is either on the same line as the last method argument, or a new line.
When using the symmetrical
(default) style:
If a method call's opening brace is on the same line as the first argument of the call, then the closing brace should be on the same line as the last argument of the call.
If an method call's opening brace is on the line above the first argument of the call, then the closing brace should be on the line below the last argument of the call.
When using the new_line
style:
The closing brace of a multi-line method call must be on the line after the last argument of the call.
When using the same_line
style:
The closing brace of a multi-line method call must be on the same line as the last argument of the call.
Example:
# symmetrical: bad
# new_line: good
# same_line: bad
foo(a,
b
)
# symmetrical: bad
# new_line: bad
# same_line: good
foo(
a,
b)
# symmetrical: good
# new_line: bad
# same_line: good
foo(a,
b)
# symmetrical: good
# new_line: good
# same_line: bad
foo(
a,
b
)
Align the elements of a hash literal if they span more than one line. Open

AwsCredentials.access_key_id,
AwsCredentials.secret_access_key))

Check that the keys, separators, and values of a multi-line hash literal are aligned according to configuration. The configuration options are:
- key (left align keys)
- separator (align hash rockets and colons, right align keys)
- table (left align keys, hash rockets, and values)
The treatment of hashes passed as the last argument to a method call can also be configured. The options are:
- always_inspect
- always_ignore
- ignore_implicit (without curly braces)
- ignore_explicit (with curly braces)
Example:
# EnforcedHashRocketStyle: key (default)
# EnforcedColonStyle: key (default)
# good
{
foo: bar,
ba: baz
}
{
:foo => bar,
:ba => baz
}
# bad
{
foo: bar,
ba: baz
}
{
:foo => bar,
:ba => baz
}
Example:
# EnforcedHashRocketStyle: separator
# EnforcedColonStyle: separator
#good
{
foo: bar,
ba: baz
}
{
:foo => bar,
:ba => baz
}
#bad
{
foo: bar,
ba: baz
}
{
:foo => bar,
:ba => baz
}
{
:foo => bar,
:ba => baz
}
Example:
# EnforcedHashRocketStyle: table
# EnforcedColonStyle: table
#good
{
foo: bar,
ba: baz
}
{
:foo => bar,
:ba => baz
}
#bad
{
foo: bar,

Unused method argument - options
. If it's necessary, use _
or _options
as an argument name to indicate that it won't be used. You can also write as initialize(*)
if you want the method to accept any arguments but don't care about them. Open
def initialize(options = {})

This cop checks for unused method arguments.

# good
