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 the IDE settings Ctrl+Alt+S.
Inspection | Description | Default Severity |
|---|---|---|
Annotator | Reports problems that are found by language annotators in the result of a batch code inspection run. | |
Duplicated code fragment | Reports duplicated blocks of code from the selected scope: the same file or the entire project. The inspection features quick-fixes that help you to set the size of detected duplicates, navigate to repetitive code fragments, and compare them in a tool window. The inspection options allow you to select the scope of the reported duplicated fragments and set the initial size for the duplicated language constructs. You can also configure the constructs that you want to anonymize in Preferences | Editor | Duplicates. | |
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\n in Settings | Editor | Code Style | Line separator, while the file you are editing uses \r\n as a line separator. The inspection also warns you about mixed line separators within a file. | |
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
| |
Problematic whitespace | Reports the following problems:
| |
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suppression | Reports usages of the following elements that can be safely removed because the inspection they affect is no longer applicable in this context:
public class C {
// symbol is already private,
// but annotation is still around
@SuppressWarnings({"WeakerAccess"})
true;
void f() {
CONST = false;
}
}
| |
Syntax error | Reports syntax errors that have been found in the result of a batch code inspection run. | |
TODO comment | Reports TODO comments in your code. You can configure the format for TODO comments in Settings | Editor | TODO. Since syntax highlighting for TODO comments is already provided, this inspection is efficient if you run it in the batch mode. | |
The line is longer than allowed by code style | Reports lines that are longer than the right margin parameter specified in the Code Style settings. |
