Behavior

  • The public identifier BSL014 and alias LineLength are stable.
  • The rule reports the cases documented on this page.
  • Suppressions and project configuration are applied before publication.
  • The rule requires neither an external analyzer nor network access.

Configuration and suppression

BSL### is the primary stable identifier. The compatible alias is accepted in select, ignore, and compatible block suppression comments.

[tool.onec-hbk-bsl]
select = ["BSL014"]
ignore = ["LineLength"]

All three suppression families support both a current line and a range. When an opening comment follows code, it affects only that line. Use any one form:

  • noqa:
Value = "example";  // noqa: BSL014
  • bsl-disable:
Value = "example";  // bsl-disable: BSL014
  • compatible BSLLS form:
Value = "example";  // BSLLS:LineLength-off

When the same opening comment is on a line by itself, it starts a range. Close it with the matching marker from the same family:

// noqa: BSL014
// code without this diagnostic
// noqa-enable: BSL014

// bsl-disable: BSL014
// code without this diagnostic
// bsl-enable: BSL014

// BSLLS:LineLength-off
// code without this diagnostic
// BSLLS:LineLength-on

To disable the rule until the end of the file, omit the closing noqa-enable, bsl-enable, or BSLLS:…-on marker.

Opening and closing markers must belong to the same family.

Description

If the line length is grater than 120 characters you should you line break. It is not recommended to have lines longer than 120 characters, except when line break is impossible (example, in code we have a string constant which is displayed without line breaks in message window using object MessageToUser).
