NAME

App::DataDirUtils - (DEPRECATED) CLI utilities related to datadirs

VERSION

This document describes version 0.003 of App::DataDirUtils (from Perl distribution App-DataDirUtils), released on 2021-08-23.

DEPRECATION NOTICE

This distribution is deprecated in favor of the more general App::TaggedDirUtils.

SYNOPSIS

See CLIs included in this distribution.

DESCRIPTION

This distribution includes several utilities related to datadirs:

• list-datadirs

A "datadir" is a directory which has a (usually empty) file called .tag-datadir. A datadir usually does not contain other datadirs.

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

FUNCTIONS

list_datadirs

Usage:

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

Search datadirs recursively in a list of directory names.

Note: when a datadir is found, its contents are no longer recursed to search for other datadirs.

This function is not exported.

Arguments ('*' denotes required arguments):

• detail => bool

• prefixes* => array[dirname]

  Locations to find datadirs.

  Directory name(s) to search for "datadirs", i.e. directories which have .tag-datadir file in its root.

• skip_git => bool (default: 1)

  Do not recurse into .git directory.

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 datadir?

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 datadir
    media-2020b/ -> a datadir
  2021/
    media-2021a/ -> a datadir
  etc/
    foo -> a datadir
    others/
      bar/ -> a datadir

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

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.
