An attribute name whose spelling is too similar to one of FIDL's official attributes will result in a compiler warning:
{% include “docs/reference/fidl/language/error-catalog/label/_bad.md” %}
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0145.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
In the above example, the attribute @duc is too similar in spelling to the official FIDL attribute @doc. In cases like this, the attribute naming is intentional, and not an accidental misspelling of an official FIDL attribute, it should be modified to be sufficiently unique:
{% include “docs/reference/fidl/language/error-catalog/label/_good.md” %}
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0145.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
Besides spell checking, the purpose of this warning is to discourage using names that are too similar to official FIDL attributes.
The typo detection algorithm works by calculating the edit distance of the attribute name from every official FIDL attribute. Names that are too similar, defined as having too small of an edit distance, trigger the typo detector.
