NAME
Perl::Critic::Policy::CodeLayout::LimitLineLength - Limit the length of lines
VERSION
version v0.1.0
SYNOPSIS
[CodeLayout::LimitLineLength]
max_line_length = 72
# Bad - line exceeds configured maximum
my $very_long_variable_name = "long string that exceeds maximum length";
# Good - line within limit
my $very_long_variable_name =
"long string that exceeds maximum length";DESCRIPTION
This policy flags lines that exceed a configurable maximum length. Long lines can be difficult to read, especially in narrow terminal windows or when viewing code side-by-side with diffs or other files.
The default maximum line length is 80 characters, which provides good readability across various display contexts while still allowing reasonable code density.
You can configure perltidy to keep lines within the specified limit. Only when it is unable to do that will you need to manually make changes.
CONFIGURATION
max_line_length
The maximum allowed line length in characters. Defaults to 80.

Long Variable Assignments
# Bad - exceeds 72 characters
my $configuration_manager = VeryLongModuleName::ConfigurationManager->new;
# Good - broken into multiple lines

$param1, $param2, $param3, $param4
);Long String Literals
# Bad - exceeds 72 characters
