File::PerlMove - Rename files using Perl expressions
use File::PerlMove qw(pmv); pmv( sub { lc($_[0]) }, \@filelist, { verbose => 1 });
File::PerlMove provides a single subroutine: File::PerlMove::pmv.
pmv takes three arguments: transform, filelist, and options.
transform must be a string or a code reference. If it is a string, it is assumed to be a valid Perl expression that will be evaluated to modify $_.
$_
When transform is invoked it should transform a file name passes as argument into a new file name.
filelist must be an array reference containing the list of file names to be processed.
options is a hash reference containing options to the operation.
Options are enabled when set to a non-zero (or otherwise 'true') value. Possible options are:
Show the changes, but do not rename the files.
Link instead of rename.
Symlink instead of rename. Note that not all platforms support symlinking,
Process the files in reversed order.
Overwrite existing files.
Create target directories if necessary.
If transform is a code reference, it is called with the old name as argument and must return the new, transformed name.
If legacy is true, the code reference adheres to the old API where the routine modifies the filename stored in $_.
More verbose information.
The main subroutine pmv() can be exported on demand.
If the transform argument is a verb, File::PerlMove will try to load (require) a package File::PerlMove::verb. This package must define a subroutine File::PerlMove::verb::verb. This subroutine is then used to perform the transformation.
If such a package cannot be loaded it may be the name of a builtin routine. See "BUILTINS".
If the transform argument is in the form pkg=verb then File::PerlMove::pkg is used instead of File::PerlMove::verb. This makes it possible to have extension modules that define multiple transform routines.
If the package name contains :: it is taken to be the full package name. For example,
::
t::foo=bar
will load package t::foo and call subroutine t::foo::bar.
If the transform argument is a verb and not an extension (see "EXTENSIONS"), it may be the name of a builtin routine.
Currently supported builtins:
Performs a lowercase operation.
Performs an uppercase operation.
Upcases the first letter.
Performs a titlecase operation.
Note, however, that using any of these operations is useless on file systems that are case insensitive, like MS Windows and Mac.
See pmv for examples.
