Load All Package Code

Description

Sources all R files in a package for interactive development, without requiring a full install.

Usage

load_all(path = ".", env = new.env(parent = globalenv()), quiet = TRUE)

Arguments

`path`	Path to package root directory.
`env`	Environment to source files into. Defaults to a fresh environment whose parent is the global environment.
`quiet`	Logical. Suppress file sourcing messages? Default TRUE.

Value

The environment into which files were sourced (invisibly). Does not modify the search path. If you want search-path behavior, call 'attach()' yourself:

attach(tinypkgr::load_all(), name = "tinypkgr:mypkg")

Examples

# Scaffold a throwaway package in tempdir() and source its R/ files.
pkg <- file.path(tempdir(), "loadpkg")
dir.create(file.path(pkg, "R"), recursive = TRUE, showWarnings = FALSE)
writeLines(c(
  "Package: loadpkg",
  "Title: Example",
  "Version: 0.0.1",
  "Authors@R: person('A', 'B', email = 'a@b.com', role = c('aut','cre'))",
  "Description: Example.",
  "License: GPL-3"
), file.path(pkg, "DESCRIPTION"))
writeLines("add <- function(x, y) x + y", file.path(pkg, "R", "add.R"))

e <- load_all(pkg)
e$add(2, 3)

unlink(pkg, recursive = TRUE)
