Back in early 2018, the prrd package was introduced as release 0.0.1, uploaded to CRAN, and updated once as release 0.0.2. I have used it extensively for every CRAN release of Rcpp, RcppArmadillo, RcppEigen, BH, and possibly others.

The idea of prrd is simple, and described in some more detail on its webpage and its GitHub repo. Reverse dependency checks are an important part of package development and is easily done in a (serial) loop. But these checks are also generally embarassingly parallel as there is no or little interdependency between them (besides maybe shared build depedencies). See the following (dated) screenshot (running six parallel workers, arranged in split byobu session).

Since the two early releases, I made a few changes to e.g. the analysis of package checks and their summaries (but never pushed these) as well as a few usability enhancements. This release regroups these.

The release is summarised in the NEWS entry:

Changes in prrd version 0.0.3 (2020-04-19)

• Extended functionality summarise() with optional use of package foghorn (Dirk)

• New scripts enqueueDepends, dequeueDepends and summmariseJobs (Dirk)

• Added tweaks and enhancements throughout (Dirk)

• The default queue location can now be set via options (Dirk)

• Meta-data on package, version and date is now stored, and shown on dequeue startup (Dirk)

• The README.md was clarified and improved (Dirk, Avraham Adler in #8, Robert Nuske in #10)

CRANberries provides the usual summary of changes to the previous version. See the aforementioned webpage and its repo for details. For more questions or comments use the issue tracker off the GitHub repo.

If you like this or other open-source work I do, you can now sponsor me at GitHub. For the first year, GitHub will match your contributions.
