Apply custom_folders additions and removals to a base folder set

Internal helper backing init_project()'s custom_folders argument.

Usage

.resolve_custom_folders(base_folders, custom_folders, preserve_parents = TRUE)

Arguments

base_folders

Character vector. The folder set to modify.

custom_folders

Character vector or NULL. Bare names add; names prefixed with "-" remove.

preserve_parents

Logical. When TRUE (the default), removing a nested folder such as "output/figures" keeps its parent "output" in the set. When FALSE, the removal is honored exactly as written and no parent is added back. init_project() passes FALSE when the base set came from a config, since a config is a complete statement of the intended structure.

Value

A character vector.
