Summary: Max rule length exceeded

Category: Style


Having too much logic placed in a single rule body.


To use helper rules and functions to compose your rules.


Splitting up large rules into smaller ones, and liberally using helper rules and functions, makes your policy easier for others to read and understand, and for yourself and your team to maintain.

Note that this rule only counts the number of lines of a rule, and currently does not take into account the actual content inside of it. Neither does it try to analyze the complexity of the code in the rule.

Configuration Options

This linter rule provides the following configuration options:

# one of "error", "warning", "ignore"
level: error
# default limit is 30 lines
max-rule-length: 30
# whether to count comments as lines
# by default, this is set to false
count-comments: false
# except rules with empty bodies from this rule, as they're
# likely an assignment of long values rather than a "rule"
# with conditions:
# users := [
# {"username": "ted"},
# {"username": "alice"},
# {"username": "bob"},
# # ... many more lines
# ]
# the default value is true
except-empty-body: true
