NAME

App::TaggedDirUtils - CLI utilities related to tagged directories

VERSION

This document describes version 0.001 of App::TaggedDirUtils (from Perl distribution App-TaggedDirUtils), released on 2021-08-23.

SYNOPSIS

See CLIs included in this distribution.

DESCRIPTION

This distribution includes several utilities related to tagged directories:

A "tagged directory" is a directory which has one or more tags: usually empty files called .tag-TAGNAME, where TAGNAME is some tag name.

You can backup, rsync, or do whatever you like with a tagged directory, just like a normal filesystem directory. The utilities provided in this distribution help you handle tagged directories.

FUNCTIONS

list_tagged_dirs

Usage:

 list_tagged_dirs(%args) -> [$status_code, $reason, $payload, \%result_meta]

Search tagged directories recursively in a list of places.

Note: when a tagged dir is found, its contents are no longer recursed to search for other tagged dirs.

This function is not exported.

Arguments ('*' denotes required arguments):

  • detail => bool

  • has_files => array[filename]

  • has_tags => array[str]

  • lacks_files => array[filename]

  • lacks_tags => array[str]

  • prefixes* => array[dirname]

    Changes file.

    Location(s) to search for tagged subdirectories, i.e. directories which have some file with specific names in its root.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)

FAQ

Why tagged directories?

With tagged directories, you can put them in various places and not just on a single parent directory. For example:

 media/
   2020/
     media-2020a/ -> a tagged dir
       .tag-media
       ...
     media-2020b/ -> a tagged dir
       .tag-media
       ...
   2021/
     media-2021a/ -> a tagged dir
       .tag-media
       ...
   etc/
     foo -> a tagged dir
       .tag-media
       ...
     others/
       bar/ -> a tagged dir
         .tag-media
         ...

As an alternative, you can also create symlinks:

 all-media/
   media-2020a -> symlink to ../media/2020/media-2020a
   media-2020b -> symlink to ../media/2020/media-2020b
   media-2021a -> symlink to ../media/2021/media-2021a
   media-2021b -> symlink to ../media/2021/media-2021b
   foo -> symlink to ../media/etc/foo
   bar -> symlink to ../media/etc/others/bar

and process entries in all-media/.

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, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
