Tools for CRAN-like Repositories
A set of functions to manage CRAN-like repositories efficiently. This
package is an alternative to
goal is to make updates to the repository easier and faster, without the
need of scanning all the package files.
cranlike keeps the package data in a SQLite database, in
addition to the
PACKAGES* files. This database is the
canonical source of the package data. It can be updated quickly, to add
and remove packages. The
PACKAGES* files are generated from
create_empty_PACKAGES creates an empty CRAN-like
repository in the specified directory. It creates the SQLite database
(if it does not exist), and also the
update_PACKAGES is similar, but it also scans the
directory for package files, and adds them to the database. Use this
function on an existing CRAN-like repository. It creates and updates the
database, and then the
add_PACKAGES adds one or more package files to the
repository. The files must already exist in the directory. The database
is created if needed, and then updated with the new packages. Then the
PACKAGES* files will be re-generated.
remove_PACKAGES removes one or more package files from
the repository. It first removes them from the database, and then
removes the files from the directory. Finally, it re-generates the
package_versions lists all packages in the repository.
It uses the SQLite database instead of parsing the
PACKAGES* files, so it is much faster.
