Use =~ in places where the MatchData returned by #match will not be used.
Open

              elsif line.match(/^Host /)
Severity: Minor
Found in modules/mu/master.rb by rubocop

This cop identifies the use of Regexp#match or String#match, which returns #<MatchData>/nil. The return value of =~ is an integral index/nil and is more performant.

Example:

# bad
do_something if str.match(/regex/)
while regex.match('str')
  do_something
end

# good
method(str =~ /regex/)
return value unless regex =~ 'str'

Redundant use of Object#to_s in interpolation.

        MU.log "Minimizing footprint of #{count.to_s} found resources", MU::DEBUG
Severity: Minor
Found in modules/mu/adoption.rb by rubocop

This cop checks for string conversion in string interpolation, which is redundant.

Example:

# bad

"result is #{something.to_s}"

Example:

# good

"result is #{something}"

Avoid more than 4 levels of block nesting.

              hashcfg.delete("id") if hashcfg["name"]
Severity: Minor
Found in modules/mu/adoption.rb by rubocop

This cop checks for excessive nesting of conditional and looping constructs.

You can configure if blocks are considered using the CountBlocks option. When set to false (the default) blocks are not counted towards the nesting level. Set to true to count blocks as well.

The maximum level of nesting allowed is configurable.

Do not suppress exceptions.

Found in modules/mu/providers/azure/vpc.rb by rubocop

This cop checks whether the end keywords are aligned properly.

Three modes are supported through the EnforcedStyleAlignWith configuration parameter:

If it's set to keyword (which is the default), the end shall be aligned with the start of the keyword (if, class, etc.).

If it's set to variable the end shall be aligned with the left-hand-side of the variable assignment, if there is one.

If it's set to start_of_line, the end shall be aligned with the start of the line where the matching keyword appears.

Example: EnforcedStyleAlignWith: keyword (default)

# bad

variable = if true
    end

# good

variable = if true
           end

Example: EnforcedStyleAlignWith: variable

# bad

variable = if true
    end

# good

variable = if true
end

Example: EnforcedStyleAlignWith: startofline

# bad

variable = if true
    end

# good

puts(if true

Severity: Minor
Found in modules/mu/mommacat.rb by rubocop

This cop checks that your heredocs are using meaningful delimiters. By default it disallows END and EO*, and can be configured through blacklisting additional delimiters.

Example:

# good
<<-SQL
  SELECT * FROM foo
SQL

# bad
<<-END
  SELECT * FROM foo
END

# bad
<<-EOS
  SELECT * FROM foo
EOS
