cōgitō analyses D code and calculates its cognitive complexity.
Run make install build/release/bin/cogito.
It will download and install the frontend and build a binary. Then you can run it on some D source:
Run ./build/release/bin/cogito src/main.d.
module app: 5 (src/main.d)
accumulateResult: 5 (src/main.d:9)
accumulateResult.(λ): 0 (src/main.d:12)
accumulateResult.(λ): 2 (src/main.d:16)
(λ): 0 (src/main.d:33)
| Property name | Allowed values | Description |
|---|---|---|
| --threshold | Positive numbers | Fail if the source score exceeds this threshold. |
| --aggregate-threshold | Positive numbers | Fail if an aggregate score exceeds this threshold. |
| --module-threshold | Positive numbers | Fail if a function score exceeds this threshold. |
| --format | flat, verbose, debug and silent |
See below. |
| --help | – | Show a help message. |
Flat format outputs only the functions violating a limit. If no limits are set, it prints all functions with their source file name and line number.
Verbose is the same as flat but it always prints all scores.
Debug output adds column numbers and scores inside aggregates.
Silent format produces no output, but returns an error if one of the thresholds is exceeded.
The return code of the program provides some information on what kind of error occurred.
- 0: Success
- 1: Command line arguments are invalid
- 2: Some source files contain errors
- 3: Function threshold violation
- 4: Aggregate threshold violation
- 5: Module threshold violation
