XAttr

Crystal bindings to XATTR.

This library allows to manage extended file attributes (XATTR). Filesystem support implemented for Linux and MacOS.

Extended attributes are name:value pairs associated permanently with files and directories and can be used to add semantic metadata, see guidelines.

Where the platform allows it, XAttr supports setting extended attributes to symlinks.

Installation

1. Add the dependency to your shard.yml:
