Package 'attachment' reference manual

Title:	Deal with Dependencies
Description:	Manage dependencies during package development. This can retrieve all dependencies that are used in ".R" files in the "R/" directory, in ".Rmd" files in "vignettes/" directory and in 'roxygen2' documentation of functions. There is a function to update the "DESCRIPTION" file of your package with 'CRAN' packages or any other remote package. All functions to retrieve dependencies of ".R" scripts and ".Rmd" or ".qmd" files can be used independently of a package development.

`document`	Run function roxygenise of roxygen2 package
`normalize`	Logical. Whether to normalize the DESCRIPTION file. See `desc::desc_normalize()`
`inside_rmd`	Logical. Whether function is run inside a Rmd, in case this must be executed in an external R session
`must.exist`	Logical. If TRUE then an error is given if packages do not exist within installed packages. If NA, a warning.
`check_if_suggests_is_installed`	Logical. Whether to require that packages in the Suggests section are installed.

Details

Your daily use is to run att_amend_desc(), as is. You will want to run this function sometimes with some extra information like att_amend_desc(pkg_ignore = "x", update.config = TRUE) if you have to update the configuration file. Next time att_amend_desc() will use these parameters from the configuration file directly.

Value

Update DESCRIPTION file.

Examples


# Run on an external "dummypackage" as an example
# For your local use, you do not have to specify the `path` as below
# By default, `att_amend_desc()` will run on the current working directory

tmpdir <- tempfile(pattern = "description")
dir.create(tmpdir)
file.copy(system.file("dummypackage",package = "attachment"), tmpdir,
 recursive = TRUE)
dummypackage <- file.path(tmpdir, "dummypackage")

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
)
att_to_desc_from_is(
  path.d = "DESCRIPTION",

  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

tmpdir <- tempfile(pattern = "descfromis")
dir.create(tmpdir)
file.copy(system.file("dummypackage",package = "attachment"), tmpdir,

Create reproducible environments for your R projects with renv

  path = ".",
  dev_pkg = "_default",
  folder_to_include = c("dev", "data-raw"),
  output = "renv.lock",

  path = ".",
  dev_pkg = "_default",
  folder_to_include = c("dev", "data-raw"),
  output = "renv.lock",
  install_if_missing = TRUE,
  document = TRUE,
  pkg_ignore = NULL,
  check_if_suggests_is_installed = TRUE,
  ...
)

create_renv_for_prod(
  path = ".",
  output = "renv.lock.prod",
  dev_pkg = "remotes",
  check_if_suggests_is_installed = FALSE,
  ...
)

Arguments

`path`	Path to your current package source folder
`dev_pkg`	Vector of packages you need for development. Use `⁠_default⁠` (with underscore before to avoid confusing with a package name), to use the default list. Use `NULL` for no extra package. Use `attachment:::extra_dev_pkg` for the list.
`folder_to_include`	Folder to scan to detect development packages
`output`	Path and name of the file created, default is `./renv.lock`
`install_if_missing`	Logical. Install missing packages. `TRUE` by default
`document`	Logical. Whether to run `att_amend_desc()` before detecting packages in DESCRIPTION.
`pkg_ignore`	Vector of packages to ignore from being discovered in your files. This does not prevent them to be in "renv.lock" if they are recursive dependencies.
`check_if_suggests_is_installed`	Logical. Whether to require that packages in the Suggests section are installed.
`...`	Other arguments to pass to `renv::snapshot()`

Value

a renv.lock file
