Code Inspections in General
This topic lists all JetBrains Rider code inspections available in General.
You can toggle specific inspections or change their severity level on the Editor | Inspection Settings | Inspection Severity | Other Languages page of settings Ctrl+Alt+S.
Inspection | Description | Default Severity |
|---|---|---|
Annotator | Reports issues essential to this file (e.g., syntax errors) in the result of a batch code inspection run. These kinds of issues are usually always highlighted when you open the file in the editor and can't be configured (unlike inspections). The options below are controlling the analysis level of this inspection:
| |
Empty directory | Reports empty directories. Available only from Code | Inspect Code or Code | Analyze Code | Run Inspection by Name and isn't reported in the editor. Use the Only report empty directories located under a source folder option to have only directories under source roots reported. | |
Inconsistent line separators | Reports files with line separators different from the ones that are specified in the project's settings. For example, the inspection will be triggered if you set the line separator to The inspection also warns you about mixed line separators within a file. | |
Incorrect formatting | Reports formatting issues that appear if your code doesn't follow your project's code style settings. This inspection is not compatible with languages that require third-party formatters for code formatting, for example, Go or C with CLangFormat enabled. | |
Injected references | Reports unresolved references injected by Language Injections. Example:
@Language("file-reference")
String fileName = "/home/user/nonexistent.file"; // highlighted if file doesn't exist
| |
Line is longer than allowed by code style | Reports lines that are longer than the Hard wrap at parameter specified in Settings | Editor | Code Style | General. | |
Problematic whitespace | Reports the following problems:
| |
Qodana service message | Reports the Qodana service messages such as suspending a particular inspection due to a large number of reported problems. | |
Reassigned to plain text | Reports files that were explicitly re-assigned to Plain Text File Type. This association is unnecessary because the platform auto-detects text files by content automatically. You can dismiss this warning by removing the file type association in Settings | Editor | File Types | Text. | |
Redundant suppression | Reports usages of the following elements that can be safely removed because the inspection they affect is no longer applicable in this context:
Example:
public class C {
// symbol is already private,
// but annotation is still around
@SuppressWarnings({"WeakerAccess"})
true;
void f() {
CONST = false;
}
}
| |
TODO comment | Reports TODO comments in your code. You can configure the format for TODO comments in Settings | Editor | TODO. Enable the Only warn on TODO comments without any details option to only warn on empty TODO comments, that don't provide any description on the task that should be done. Disable to report all TODO comments. |
