class RuboCop::Cop::Style::TrailingCommaInArguments
Checks for trailing comma in argument lists. The supported styles are:
-
‘consistent_comma`: Requires a comma after the last argument,
for all parenthesized method calls with arguments.
-
‘comma`: Requires a comma after the last argument, but only for
parenthesized method calls where each argument is on its own line.
-
‘no_comma`: Requires that there is no comma after the last
argument.
@example EnforcedStyleForMultiline: consistent_comma
# bad method(1, 2,) # good method(1, 2) # good method( 1, 2, 3, ) # good method( 1, 2, 3, ) # good method( 1, 2, )
@example EnforcedStyleForMultiline: comma
# bad method(1, 2,) # good method(1, 2) # bad method( 1, 2, 3, ) # good method( 1, 2, 3 ) # bad method( 1, 2, 3, ) # good method( 1, 2, 3 ) # good method( 1, 2, )
@example EnforcedStyleForMultiline: no_comma (default)
# bad method(1, 2,) # good method(1, 2) # good method( 1, 2 )
