This script enumerates dependencies for packages in a void-packages repository and identifies build-time dependency cycles. It is based on earlier scripts provided by the Void maintainer @Chocimier. The key differences are
- No intermediate files are created
- Dependency enumeration is parallelized by default
- Output provides a more illustrative view of cycles
For command syntax, run xbps-cycles.py -h. Often, it may be sufficient to run
xbps-cycles.py with no arguments. By default, the script will look for a
repository at $XBPS_DISTDIR; if that variable is not defined, the current
directory is used instead. To override this behavior, use the -d option to
provide the path to your desired void-packages clone.
The standard behavior will be to spawn multiple processes, one per CPU, to
enumerate package dependencies. This is by far the most time-consuming part of
the execution. To override the degree of parallelism, use the -j option.
Failures should be harmless but, at this early stage, unlikely to be pretty or even helpful.
