Copy derivations from the Nix store to current working directory

Source: R/rxp_copy.R
rxp_copy.Rd

When Nix builds a derivation, its output is saved in the Nix store located under /nix/store/. Even though you can import the derivations into the current R session using rxp_read() or rxp_load(), it can be useful to copy the outputs to the current working directory. This is especially useful for Quarto documents, where there can be more than one input, as is the case for html output.

Usage

rxp_copy(derivation_name = NULL, dir_mode = "0755", file_mode = "0644")

Arguments

derivation_name

The name of the derivation to copy. If empty, then all the derivations are copied.

dir_mode

Character, default "0755". POSIX permission mode to apply to directories under the copied output (including the top-level output directory).

file_mode

Character, default "0644". POSIX permission mode to apply to files under the copied output.

Value

Nothing, the contents of the Nix store are copied to the current working directory.
