install_exiftool {exiftoolr}

Install ExifTool, downloading (by default) the current version

Description

Install the current version of ExifTool

Usage

install_exiftool(
  install_location = NULL,
  win_exe = NULL,
  local_exiftool = NULL,
  quiet = FALSE
)

Arguments

install_location

Path to the directory into which ExifTool should be installed. If NULL (the default), installation will be into the directory returned by backports::R_user_dir("exiftoolr").

win_exe

Logical, only used on Windows machines. Should we install the standalone ExifTool Windows executable or the ExifTool Perl library? (The latter relies, for its execution, on an existing installation of Perl being present on the user's machine.) If set to NULL (the default), the function installs the Windows executable on Windows machines and the Perl library on other operating systems.

local_exiftool

If installing ExifTool from a local "*.zip" or ".tar.gz", supply the path to that file as a character string. With default value, 'NULL', the function downloads ExifTool from https://exiftool.org and then installs it.

quiet

Logical. Should function should be chatty?

Value

Called for its side effect
