adf_directory: Changing and creating directories on a virtual device

In adfExplorer: Access and Manipulate Amiga Disk Files

Changing and creating directories on a virtual device

Description

adf_directory() shows the current directory of a virtual device, when a file system is present. When connecting to or creating a new device, the current directory is the disk's root by default. To change the current directory, use adf_directory() in combination with the assign operator (⁠<-⁠).

Usage

adf_directory(dev, ...)

## S3 method for class 'adf_device'
adf_directory(dev, ...)

adf_directory(dev, ...) <- value

## S3 replacement method for class 'adf_device'
adf_directory(dev, ...) <- value

## S3 replacement method for class 'adf_device.character'
adf_directory(dev, ...) <- value

## S3 replacement method for class 'adf_device.virtual_path'
adf_directory(dev, ...) <- value

make_adf_dir(x, path, ...)

## S3 method for class 'adf_device'
make_adf_dir(x, path, ...)

## S3 method for class 'virtual_path'
make_adf_dir(x, path, ...)

## S3 method for class 'character'
make_adf_dir.adf_device(x, path, ...)

## S3 method for class 'virtual_path'
make_adf_dir.adf_device(x, path, ...)

Arguments

dev	The virtual adf device for which information needs to be obtained. It should be of class adf_device which can be created with create_adf_device() or connect_adf().
...	Ignored
value	A character string or a virtual_path (see virtual_path()) representing directory you wish to set as current.
x	An adf_device or virtual_path class object. The first specifies the device on which a directory needs to be created. The latter specifies both the directory and the device on which it needs to be created.
path	A character string or a virtual_path (see virtual_path()) specifying the name of the new directory to be created. Should be missing when x is of class virtual_path

Details

To create a new directory on a device use make_adf_dir() and use a full or relative path name to specify the new directory name.

See vignette("virtual_paths") for a note on file and directory names on the Amiga.

Value

make_adf_dir() returns the device connection. adf_directory() returns the current directory as a virtual_path class object.

Examples

## Open virtual device to demonstrate methods
my_device <- demo_adf(write_protected = FALSE)

## Show the current directory
adf_directory(my_device)

## Create a new directory
make_adf_dir(my_device, "DF0:s/newdir")

## Change the current dir to the new directory:
adf_directory(my_device) <- "DF0:s/newdir"

## Close the virtual device
close(my_device)
