find_functions {functiondepends}

Functions in path

Description

Parses files in given path. It searches for functions and loads them. Is safe for use with scripts as it doesn't source the whole file, just functions. There are no side-effects to sourcing .R files.

Usage

find_functions(
  path,
  envir = new.env(),
  recursive = TRUE,
  separate_path = FALSE
)

Arguments

path

Character, path to folder

envir

Environment to source loaded functions into

recursive

Logical, whether to search files recursively

separate_path

Logical, whether to split path into hierarchy of directories. Produces multiple character columns with 'Level' prefix.

Value

A tibble with character columns indicating path to source files and names of functions defined in them.

Examples

path <- file.path(tempdir(), "find_functions_example")
dir.create(path, showWarnings = FALSE)
code <- "
add <- function(x, y) {
  x + y
}
add_one = function(x) {
  add(x, 1)
}
assign('add_two', function(x) {
  add(x, 2)
})
"
write(code, file.path(path, "code.R"))
find_functions(path)
