R: Create or update PACKAGES* files for a CRAN-like repository

update_PACKAGES {cranlike}

R Documentation

Create or update PACKAGES* files for a CRAN-like repository

Description

This function is similar to tools::write_PACKAGES(), with some differences:

It always uses the MD5sum field.
It defaults to addFiles = TRUE, to allow following the package files better.
It does not support the verbose, unpacked, and subdirs arguments currently.
It uses a database to speed up the indexing process, and only reindexes files that have added, removed or updated.

Usage

update_PACKAGES(dir = ".", fields = NULL, type = c("source", "mac.binary",
  "win.binary"))

Arguments

dir

Character vector describing the location of the repository (directory including source or binary packages) to generate the ‘PACKAGES’, ‘PACKAGES.gz’ and ‘PACKAGES.rds’ files from and write them to.

fields

a character vector giving the fields to be used in the ‘PACKAGES’, ‘PACKAGES.gz’ and ‘PACKAGES.rds’ files in addition to the default ones, or NULL (default).

The default corresponds to the fields needed by available.packages: "Package", "Version", "Priority", "Depends", "Imports", "LinkingTo", "Suggests", "Enhances", "OS_type", "License" and "Archs", and those fields will always be included, plus the file name in field "File" if addFile = TRUE and the path to the subdirectory in field "Path" if subdirectories are used.

type

Type of packages: currently source ‘.tar.gz,bz2,xz’ archives, and macOS or Windows binary (‘.tgz’ or ‘.zip’, respectively) packages are supported. Defaults to "win.binary" on Windows and to "source" otherwise.

Details

update_PACKAGES uses a SQLite database to aid updating PACKAGES* files quickly. It this database does not exist, then it will be created based on the existing PACKAGES* files. If no PACKAGES* files exist, either, then these will be created via tools::write_PACKAGES().
