Behavior¶
- The public identifier
BSL212and aliasMissedRequiredParameterare 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.
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:
bsl-disable:
- compatible
BSLLSform:
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: BSL212
// code without this diagnostic
// noqa-enable: BSL212
// bsl-disable: BSL212
// code without this diagnostic
// bsl-enable: BSL212
// BSLLS:MissedRequiredParameter-off
// code without this diagnostic
// BSLLS:MissedRequiredParameter-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¶
Required parameters must not be omitted when calling methods, otherwise the value Undefined will be passed to the parameter, which the method often cannot process.
If the value Undefined is valid, then you need to
- explicitly pass a value
- or make the parameter optional with a default value of Undefined.
Examples¶
For example
Incorrect:
ChangeFormFieldColor(,"Result", StyleColors.ArthursShirtColor); // missing first parameter Form
ChangeFormFieldColor(,,); // missing all required parameters
Correct:
