NAME

App::SymlinkUtils - CLI utilities related to symbolic links (symlinks)

VERSION

This document describes version 0.004 of App::SymlinkUtils (from Perl distribution App-SymlinkUtils), released on 2023-08-25.

DESCRIPTION

This distribution includes several utilities related to symlinks:

FUNCTIONS

Usage:

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

Perform various checks on a symlink.

This function is not exported.

Arguments ('*' denotes required arguments):

  • content_matches => bool

    Whether content should match extension.

    If set to true, will guess media type from content and check that file extension exists nd matches the media type. Requires File::MimeInfo::Magic, which is only specified as a "Recommends" dependency by File-Symlink-Util distribution.

  • ext_matches => bool

    Whether extension should match.

    If set to true, then if both symlink name and target filename contain filename extension (e.g. jpg) then they must match. Case variation is allowed (e.g. JPG) but other variation is not (e.g. jpeg).

  • is_abs => bool

    Whether we should check that symlink target is an absolute path.

    If set to true, then symlink target must be an absolute path. If set to false, then symlink target must be a relative path.

  • symlink* => filename

    Path to the symlink to be checked.

  • target => filename

    Expected target path.

    If specified, then target of symlink (after normalized to absolute path) will be checked and must point to this target.

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)

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.
