App::DataDirUtils - (DEPRECATED) CLI utilities related to datadirs
This document describes version 0.003 of App::DataDirUtils (from Perl distribution App-DataDirUtils), released on 2021-08-23.
This distribution is deprecated in favor of the more general App::TaggedDirUtils.
See CLIs included in this distribution.
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.
Usage:
list_datadirs(%args) -> [$status_code, $reason, $payload, \%result_meta]
Search datadirs recursively in a list of directory names.
Note: when a datadir is found, its contents are no longer recursed to search for other datadirs.
This function is not exported.
Arguments ('*' denotes required arguments):
detail => bool
prefixes* => array[dirname]
Locations to find datadirs.
Directory name(s) to search for "datadirs", i.e. directories which have .tag-datadir file in its root.
.tag-datadir
skip_git => bool (default: 1)
Do not recurse into .git directory.
Returns an enveloped result (an array).
First element ($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)
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

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.
