Code Inspections in EditorConfig

This topic lists all JetBrains Rider code inspections available in EditorConfig.

You can toggle specific inspections or change their severity level on the Editor | Inspection Settings | Inspection Severity | Other Languages page of the IDE settings Ctrl+Alt+S.

Inspection	Description	Default Severity
Deprecated property	Reports EditorConfig properties that are no longer supported.	Warning
Duplicate character class letter	Reports wildcard patterns in the EditorConfig section that contain a duplicate character in the character class, for example `[aa]`.	Warning
Duplicate or redundant pattern	Reports file patterns that are redundant as there already are other patterns that define the same scope of files or even a broader one. For example, in `[{.java,}]` the first `.java` pattern defines a narrower scope compared to ``. That is why it is redundant and can be removed.	Warning
EditorConfig section is not unique	Reports sections that define the same file pattern as other sections.	Warning
Empty header	Reports sections with an empty header. Section header must contain file path globs in the format similar to one supported by `gitignore`.	Error
Empty section	Reports sections that do not contain any EditorConfig properties.	Warning
Extra top-level declaration	Reports multiple top-level declarations. There can be only one optional “root=true” top-level declaration in the EditorConfig file. Using multiple top-level declarations is not allowed.	Error
Invalid property value	Reports property values that do not meet value restrictions. For example, some properties may be only “true” or “false”, others contain only integer numbers etc. If a value has a limited set of variants, use code completion to see all of them.	Error
Invalid reference	Reports identifiers that are either unknown or have a wrong type.	Error
No matching files	Reports sections with wildcard patterns that do not match any files under the directory in which the `.editorconfig` file is located.	Warning
Non-unique list value	Reports duplicates in lists of values.	Error
Overlapping sections	Reports subsets of files specified in the current section that overlap with other subsets in other sections. For example: `[{foo,bar}]` and `[{foo,bas}]` both contain “foo”.	Weak warning
Overridden property	Reports properties that are already defined in other sections. For example: [.java] indent_size=4 [{.java,.js}] indent_size=2 The second section includes all `.java` files too but it also redefines indent_size. As a result the value 2 will be used for files matching `*.java`.	Warning
Overriding property	Reports properties that override the same properties defined earlier in the file. For example: [.java] indent_size=4 [{.java,.js}] indent_size=2 The second section includes the same files as `[.java]` but also sets indent_size to value 2. Thus the first declaration `indent_size=4` will be ignored.	Warning
Redundant property	Reports properties that are redundant when another applicable section already contains the same property and value. For example: [] indent_size=4 [.java] indent_size=4 are both applicable to `*.java` files and define the same `indent_size` value.	Warning
Redundant wildcard	Reports wildcards that become redundant when the “” wildcard is used in the same section. The “” wildcard defines a broader set of files than any other wildcard. That is why, any other wildcard used in the same section has no affect and can be removed.	Warning
Required declarations are missing	Reports properties that miss the required declarations. Refer to the documentation for more information.	Error
Space in file pattern	Reports space characters in wildcard patterns that affect pattern matching. If these characters are not intentional, they should be removed.	Weak warning
Too many wildcards	Reports sections that contain too many wildcards. Using a lot of wildcards may lead to performance issues.	Weak warning
Unexpected comma	Reports commas that cannot be used in the current context. Commas are allowed only as separators for values in lists.	Error
Unexpected key-value pair	Reports key-value pairs that are not allowed in the current context.	Error
Unexpected top-level declaration	Reports unexpected top-level declarations. Top-level declarations other than “root=true” are not allowed in the EditorConfig file.	Error
Unexpected value list	Reports lists of values that are used in properties in which lists are not supported. In this case, only a single value can be specified.	Error
Unknown property	Reports properties that are not supported by the IDE. Note: some “ij” domain properties may require specific language plugins.	Warning
Unnecessary braces	Reports pattern lists that are either empty `{}` or contain just one pattern, for example `{foo}`. The braces are needed only if there are two and more, for example: `{foo,bar}`	Error
Unnecessary character class	Reports character classes that consist of a single character. Such classes can be simplified to a character, for example `[a]` → `a`.	Warning
Unused declaration	Reports unused declarations. Such declarations can be removed.	Warning
