.IX Title "Plain 3"
.TH Plain 3 "2006-07-30" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
Filesys::Virtual::Plain \- A Plain virtual filesystem
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&        use Filesys::Virtual::Plain;
.Ve
.PP
.Vb 1
\&        my $fs = Filesys::Virtual::Plain->new();
.Ve
.PP

.Ve
.PP
.Vb 1
\&        print foreach ($fs->list('/'));
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module is used by other modules to provide a pluggable filesystem.
.SH "CONSTRUCTOR"
.IX Header "CONSTRUCTOR"
.Sh "\fInew()\fP"
.IX Subsection "new()"
You can pass the initial cwd, root_path, and home_path as a hash.
.SH "METHODS"
.IX Header "METHODS"
.ie n .Sh "login($username, $password\fP, \f(CW$become)"
.el .Sh "login($username, \f(CW$password\fP, \f(CW$become\fP)"
.IX Subsection "login($username, $password, $become)"
Logs in a user.  Returns 0 on failure.  If \f(CW$username\fR is 'anonymous' then it
will try to login as 'ftp' with no password.  If \f(CW$become\fR is defined then it
will try to change ownership of the process to the uid/gid of the logged in
user.  \s-1BEWARE\s0 of the consequences of using \f(CW$become\fR.  \fIlogin()\fR also sets the 
uid, gid, home, gids, home_path, and chdir to the users'.
.Sh "cwd"
.IX Subsection "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.
.Sh "root_path($path)"
.IX Subsection "root_path($path)"
Get or set the root path.  All file paths are  off this and cwd
For example:
.PP
.Vb 3
\&        $self->root_path('/home/ftp');
\&        $self->cwd('/test');
\&        $self->size('testfile.txt');
.Ve
.PP
The size command would get the size for file /home/ftp/test/testfile.txt
not /test/testfile.txt
.Sh "chmod($mode,$file)"
.IX Subsection "chmod($mode,$file)"
chmod's a file.
.Sh "modtime($file)"
.IX Subsection "modtime($file)"
Gets the modification time of a file in \s-1YYYYMMDDHHMMSS\s0 format.
.Sh "size($file)"
.IX Subsection "size($file)"
Gets the size of a file in bytes.
.Sh "delete($file)"
.IX Subsection "delete($file)"
Deletes a file, returns 1 or 0 on success or failure.
.Sh "chdir($dir)"
.IX Subsection "chdir($dir)"
Changes the cwd to a new path from root_path.
Returns undef on failure or the new path on success.
.ie n .Sh "mkdir($dir, $mode)"
.el .Sh "mkdir($dir, \f(CW$mode\fP)"
.IX Subsection "mkdir($dir, $mode)"
Creats a directory with \f(CW$mode\fR (defaults to 0755) and \fIchown()\fR's the directory
with the uid and gid.  The return value is from \fImkdir()\fR.
.Sh "rmdir($dir)"
.IX Subsection "rmdir($dir)"
Deletes a directory or file if \-d test fails.  Returns 1 on success or 0 on
failure.
.Sh "list($dir)"
.IX Subsection "list($dir)"
Returns an array of the files in a directory.
.Sh "list_details($dir)"
.IX Subsection "list_details($dir)"
Returns an array of the files in ls format.
.Sh "stat($file)"
.IX Subsection "stat($file)"
Does a normal \fIstat()\fR on a file or directory
.Sh "test($test,$file)"
.IX Subsection "test($test,$file)"
Perform a perl type test on a file and returns the results.
.PP
For example to perform a \-d on a directory.
.PP
.Vb 1
\&        $self->test('d','/testdir');
.Ve
.PP
See filetests in perlfunc (commandline: perldoc perlfunc)
.Sh "open_read($file,[params])"
.IX Subsection "open_read($file,[params])"
Opens a file with IO::File. Params are passed to \fIopen()\fR of IO::File.
It returns the file handle on success or undef on failure.  This could
be technically be used for any sort of open operation.  See IO::File's
open method.
.Sh "close_read($fh)"
.IX Subsection "close_read($fh)"
Performs a \f(CW$fh\fR\->\fIclose()\fR
.ie n .Sh "open_write($fh, $append)"
.el .Sh "open_write($fh, \f(CW$append\fP)"
.IX Subsection "open_write($fh, $append)"
Performs an \f(CW$fh\fR\->open(\*(L">$file\*(R") or \f(CW$fh\fR\->open(\*(L">>$file\*(R") if \f(CW$append\fR is defined.
Returns the filehandle on success or undef on failure.
.Sh "close_write($fh)"
.IX Subsection "close_write($fh)"
Performs a \f(CW$fh\fR\->\fIclose()\fR
.ie n .Sh "seek($fh, $pos\fP, \f(CW$wence)"
.el .Sh "seek($fh, \f(CW$pos\fP, \f(CW$wence\fP)"
.IX Subsection "seek($fh, $pos, $wence)"
Performs a \f(CW$fh\fR\->seek($pos, \f(CW$wence\fR). See IO::Seekable.
.ie n .Sh "utime($atime, $mtime\fP, \f(CW@files)"
.el .Sh "utime($atime, \f(CW$mtime\fP, \f(CW@files\fP)"
.IX Subsection "utime($atime, $mtime, @files)"
Performs a \fIutime()\fR on the file(s).  It changes the access time and mod time of
those files.
