dot-urlRemapFn: Resolve the 'reproducible.urlRemap' option to a remap...

In reproducible: Enhance Reproducibility of R Code

Resolve the reproducible.urlRemap option to a remap function

Description

Internal. The reproducible.urlRemap option may be set to any of:

• NULL – no remapping;

• a ⁠function(url, filename)⁠ (e.g. built with makeUrlRemap());

• a data.frame/data.table manifest with filename and url columns; or

• a length-one character path or URL to a CSV with those columns. This returns a single ⁠function(url, filename)⁠ (or NULL). For the data.frame/character forms it builds the function once via makeUrlRemap() and caches it (keyed on the option value), so the lookup is not rebuilt – and a CSV path/URL is not re-read – on every download. An invalid option value is ignored with a warning (returns NULL), so it can never break a download.

Usage

.urlRemapFn(opt = getOption("reproducible.urlRemap"))

Arguments

opt	The current value of the reproducible.urlRemap option.

Value

A ⁠function(url, filename)⁠ or NULL.
