NAME

App::perlmv::scriptlet::add_prefix_datestamp - Add datestamp prefix (YYYYMMDD-) to filenames, using files' modification time as date

VERSION

This document describes version 0.003 of App::perlmv::scriptlet::add_prefix_datestamp (from Perl distribution App-perlmv-scriptlet-add_prefix_datestamp), released on 2023-08-25.

SYNOPSIS

With filenames:

 foo.txt
 new-bar.txt

This command:

 % perlmv add-prefix -a prefix=new- *

will rename the files as follow:

 foo.txt -> new-foo.txt
 new-bar.txt -> new-new-bar.txt

This command:

 % perlmv add-prefix -a prefix=new- -a avoid_duplicate_prefix=1 *

will rename the files as follow:

 foo.txt -> new-foo.txt

DESCRIPTION

Adding a datestamp prefix on filenames is one of the ways I often use to organize documents. There is file modification time supplied by the filesystem, but this information does not survive through git repository or sharing across the web/mobile application. Hence putting the information in the filename.

SCRIPTLET ARGUMENTS

Arguments can be passed using the -a (--arg) perlmv option, e.g. -a name=val.

avoid_duplicate_prefix

Avoid adding prefix when filename already has prefix that looks like datestamp (1xxxxxxx- to 2xxxxxxx).

date

Use this date instead of file's modification time.

prefix_format

Specify datestamp format, in the form of strftime() template.

The default format is "%Y%m%d-" or "%Y%m%dT%H%M%S-" if you enable the with_time option. But you can customize it here.

prefix_regex

Specify how existing datestamp prefix should be recognized.

This regex is used to check for the existence of datestamp (if you use the avoid_duplicate_prefix option. The default is qr/^\d{8}(?:T\d{6})?-/ but if your existing datestamps are in different syntax you can accommodate them here.

with_time

Whether to add time (YYYYMMDD"T"hhmmss instead of just date (YYYYMMDD).

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
