pruneRepo: Prune repository from older copies of packages

Description

The function determines which packages in a repositories can be removed as they are being ‘shadowed’ by a newer version of the same packages.

Usage

getRepoInfo(repopath = getOption("dratRepo", "~/git/drat"),
  type = c("source", "binary", "mac.binary", "mac.binary.big-sur-x86_64",
  "mac.binary.big-sur-arm64", "mac.binary.el-capitan", "mac.binary.mavericks",
  "win.binary", "both"), pkg, version = getRversion(),
  location = getOption("dratBranch", "gh-pages"))
pruneRepo(repopath = getOption("dratRepo", "~/git/drat"), type = c("source",
  "binary", "mac.binary", "mac.binary.big-sur-x86_64",
  "mac.binary.big-sur-arm64", "mac.binary.el-capitan", "mac.binary.mavericks",
  "win.binary", "both"), pkg, version = getRversion(), remove = FALSE,
  location = getOption("dratBranch", "gh-pages"))
pruneRepoForAllRversions(repopath = getOption("dratRepo", "~/git/drat"),
  type = c("source", "mac.binary", "mac.binary.big-sur-x86_64",
  "mac.binary.big-sur-arm64", "mac.binary.el-capitan", "mac.binary.mavericks",
  "win.binary", "both"), pkg, remove = FALSE)
updateRepo(repopath = getOption("dratRepo", "~/git/drat"),
  type = c("source", "mac.binary", "mac.binary.big-sur-x86_64",
  "mac.binary.big-sur-arm64", "mac.binary.el-capitan", "mac.binary.mavericks",
  "win.binary", "both"), version = NA, ...)

Value

A data frame describing the repository is returned containing columns with columns “file”,

“package” (just the name), “version” and a logical variable “newest” indicating if the package can be removed.

Arguments

repopath: Character variable with the path to the repo; defaults to the value of the “dratRepo” option with “"~/git/drat"” as fallback
type: Character variable for the type of repository, so far “source”, “binary”, “win.binary”, “mac.binary”, “mac.binary.mavericks”, “mac.binary.el-capitan”, “mac.binary.big-sur-x86_64”, “mac.binary.big-sur-arm64”, or “both”
pkg: Optional character variable specifying a package name, whose older versions should be pruned. If missing (the default), pruning is performed on all packages.
version: R version information in the format X.Y or X.Y.Z. Only used, if pruning binary packages. (default: version = getRversion()). If version = NA, all available R versions will be used. If version = NULL, this defaults to getRversion().
location: An optional character variable with the GitHub Pages location: either “gh-pages” indicating a branch of that name, or “docs/” directory in the main branch. The default value can be overridden via the “dratBranch” option.
remove: Character or logical variable indicating whether files should be removed. Nothing happens if ‘FALSE’. If different from (logical) ‘FALSE’ and equal to character “git” files are removed via git rm else via a straight file deletion.
...: For updateRepo a catch-all collection of parameters. Arguments passed to update_PACKAGES currently include latestOnly, for which the default value is set here to FALSE. See update_PACKAGES. Please note that this has an effect for update_PACKAGES only, if new packages are found, e.g. manually added.

Details

Given a package name, R will always find the newest version of that package. Older versions are therefore effectively shadowed and can be removed without functionally changing a repository.

However, if a current package file is removed without pruneRepo, the PACKAGES, PACKAGES.gz and PACKAGES.rds file might be not up to date. To ensure the correct information is available in these indices, run updateRepo.

These functions are still undergoing development and polish and may change in subsequent versions.
