Amend DESCRIPTION with dependencies from imports and suggests package list

Description

Amend DESCRIPTION with dependencies from imports and suggests package list

Usage

att_to_desc_from_is(
  path.d = "DESCRIPTION",
  imports = NULL,
  suggests = NULL,
  check_if_suggests_is_installed = TRUE,
  normalize = TRUE,
  must.exist = TRUE
)

Arguments

path.d	path to description file.
imports	character vector of package names to add in Imports section
suggests	character vector of package names to add in Suggests section
check_if_suggests_is_installed	Logical. Whether to require that packages in the Suggests section are installed.
normalize	Logical. Whether to normalize the DESCRIPTION file. See desc::desc_normalize()
must.exist	Logical. If TRUE then an error is given if packages do not exist within installed packages. If NA, a warning.

Details

must.exist is better set to TRUE during package development. This stops the process when a package does not exists on your system. This avoids check errors with typos in package names in DESCRIPTION. When used in CI to discover dependencies, for a bookdown for instance, you may want to set to FALSE (no message at all) or NA (warning for not installed).

Value

Fill in Description file

Examples

tmpdir <- tempfile(pattern = "descfromis")
dir.create(tmpdir)
file.copy(system.file("dummypackage",package = "attachment"), tmpdir,
 recursive = TRUE)
dummypackage <- file.path(tmpdir, "dummypackage")
# browseURL(dummypackage)
att_to_desc_from_is(path.d = file.path(dummypackage, "DESCRIPTION"),
imports = c("magrittr", "attachment"), suggests = c("knitr"))

# In combination with other functions
att_to_desc_from_is(path.d = file.path(dummypackage, "DESCRIPTION"),
imports = att_from_rscripts(file.path(dummypackage, "R")),
suggests = att_from_rmds(file.path(dummypackage, "vignettes")))

# Clean temp files after this example
unlink(tmpdir, recursive = TRUE)
