Diff Command¶
The wily diff command will compare the last cached revision of the code with the current metrics. It will run the default metrics for the current environment.

Examples¶
To see the changes in metrics for a list of files, give the files to the wily diff
command.
$ wily diff example.py example2.py src/example3.py
The diff command will only show files where the metrics have changes, to see all files regardless of changes, provide the --all
flag.
$ wily diff example.py --all
To show specific metrics, add a combination of comma-separated --metrics
flags.
$ wily diff example.py --metrics raw.loc,cyclomatic.complexity
Diff will show function and class-level metrics by default. To show only module-level metrics, add the --no-detail
flag
$ wily diff example.py --no-detail
