@suppress annotations

Rishipal Singh Bhatia edited this page Jul 1, 2022 · 41 revisions

If you cannot easily fix a JsCompiler warning, you can suppress it using the @suppress annotation in the function's JSDoc block or the @fileoverview block or any assignment in statement position.

Example

/**
 * ...
 * Good; suppresses within the entire function.
 * Also, this suppresses multiple warnings.
 * @suppress {visibility|underscore}
 */
function blah() {
  /** @suppress {visibility} */ // Good; suppresses within this declaration only.
  otherClass.privateField_ = blah;

  /** @suppress {checkTypes} */  // Bad; doesn't work.
  foo(incompatible.type);

  /** @suppress {missingRequire} */  // Good; this is an exception (see below).
  foo(blah.not.required);
}

Other locations

Some specific @suppress annotations are allowed elsewhere:

  • @suppress {extraRequire} is valid just before a goog.require(...); statement.
  • @suppress {missingRequire} is valid on any statement.
  • @suppress {with} is valid on with statements e.g. /** @suppress {with} */ with(Math) { alert(PI);} suppresses JSC_USE_OF_WITH warning.

All other annotations can only be suppressed for a function, file, or declaration. You cannot suppress most warnings for a single line within a function.

Suppression tags

The full list of suppressions accepted by the parser can be found in the jsdoc.suppressions list here.

The specific warnings included in each suppression can be found here (note that not all groups are recognized as suppressions).

Error to suppression map

This table maps all suppressible error ids to the corresponding @suppress tag. Note that some errors are not suppressible in code and are omitted from this table.

These suppression tags are not canonical. In some cases multiple tags may suppress the same error.
