NAME ^

Filesys::Virtual::Plain - A Plain virtual filesystem

SYNOPSIS ^

        use Filesys::Virtual::Plain;

        my $fs = Filesys::Virtual::Plain->new();

        $fs->login('xantus', 'supersekret');

        print foreach ($fs->list('/'));

DESCRIPTION ^

This module is used by other modules to provide a pluggable filesystem.

CONSTRUCTOR ^

new()

You can pass the initial cwd, root_path, and home_path as a hash.

METHODS ^

login($username, $password, $become)

Logs in a user. Returns 0 on failure. If $username is 'anonymous' then it will try to login as 'ftp' with no password. If $become is defined then it will try to change ownership of the process to the uid/gid of the logged in user. BEWARE of the consequences of using $become. login() also sets the uid, gid, home, gids, home_path, and chdir to the users'.

cwd

Gets or sets the current directory, assumes / if blank. This is used in conjunction with the root_path for file operations. No actual change directory takes place.

root_path($path)

Get or set the root path. All file paths are off this and cwd For example:

        $self->root_path('/home/ftp');
        $self->cwd('/test');
        $self->size('testfile.txt');

The size command would get the size for file /home/ftp/test/testfile.txt not /test/testfile.txt

chmod($mode,$file)

chmod's a file.

modtime($file)

Gets the modification time of a file in YYYYMMDDHHMMSS format.

size($file)

Gets the size of a file in bytes.

delete($file)

Deletes a file, returns 1 or 0 on success or failure.

chdir($dir)

Changes the cwd to a new path from root_path. Returns undef on failure or the new path on success.

mkdir($dir, $mode)

Creats a directory with $mode (defaults to 0755) and chown()'s the directory with the uid and gid. The return value is from mkdir().

rmdir($dir)

Deletes a directory or file if -d test fails. Returns 1 on success or 0 on failure.

list($dir)

Returns an array of the files in a directory.

list_details($dir)

Returns an array of the files in ls format.

stat($file)

Does a normal stat() on a file or directory

test($test,$file)

Perform a perl type test on a file and returns the results.

For example to perform a -d on a directory.

        $self->test('d','/testdir');

See filetests in perlfunc (commandline: perldoc perlfunc)

open_read($file,[params])

Opens a file with IO::File. Params are passed to open() of IO::File. It returns the file handle on success or undef on failure. This could be technically be used for any sort of open operation. See IO::File's open method.

close_read($fh)

Performs a $fh->close()

open_write($fh, $append)

Performs an $fh->open(">$file") or $fh->open(">>$file") if $append is defined. Returns the filehandle on success or undef on failure.

close_write($fh)

Performs a $fh->close()

seek($fh, $pos, $wence)

Performs a $fh->seek($pos, $wence). See IO::Seekable.

utime($atime, $mtime, @files)

Performs a utime() on the file(s). It changes the access time and mod time of those files.
