cran_static_path_handler {microCRAN}

Handler for package repository files

Description

Creates handler for handling access to static files in the repository, i.e., the src/contrib, bin/windows/contrib, and bin/macosx/contrib subdirectories.

Use cran_static_redirect_handler to let another process (e.g. an Apache httpd or nginx server) handle the request, by redirecting it.

Usage

cran_static_path_handler(repo_dir, path_prefix = NULL)

cran_static_redirect_handler(dest_url)

Arguments

repo_dir

Path to local directory, where the root of the repository is. The (source) packages will be stored locally at ⁠{repo_dir}/src/contrib/⁠.

path_prefix

Optional URL-component, if the repository exists at a subdirectory of the host (see run's path). Here, it is only for decorative purposes.

dest_url

The url requests are forwarded to, after being appened with the request; it should contain all path-components up to the '/src' or '/bin' parts.

Value

A handler (function) for use in a Plumber router "filter" .

Examples

require(plumber)

  cran_static_path_handler(repo_dir, path_prefix = 'cran'))
