BSL025 - Empty statement

← All rules

Summary

Empty statement

Identifiers

Field Value
Rule code BSL025
Compatible alias EmptyStatement
Severity WARNING
Without configuration Yes
BSLLS JSON, ON mode without overrides Yes
Registry flag implemented Yes
Tags syntax, convention

The implemented flag describes the registry; it does not certify verified BSLLS parity.

Behavior

  • The public identifier BSL025 and alias EmptyStatement 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 = ["BSL025"]
ignore = ["EmptyStatement"]

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: BSL025
  • bsl-disable:
Value = "example";  // bsl-disable: BSL025
  • compatible BSLLS form:
Value = "example";  // BSLLS:EmptyStatement-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: BSL025
// code without this diagnostic
// noqa-enable: BSL025

// bsl-disable: BSL025
// code without this diagnostic
// bsl-enable: BSL025

// BSLLS:EmptyStatement-off
// code without this diagnostic
// BSLLS:EmptyStatement-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

An empty statement is an operator consisting only of a semicolon (";"). Usually appears when:

  • refactoring, when the developer deleted a part of the code, but forgot to delete the last ";"
  • "copy paste", when the developer pasted the copied code containing the final character ";"
  • inattentive, when the developer twice (or even more) times clicked the symbol ";"

An empty statement does not lead to code errors, but clutters it, reducing perception.
