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.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     xattr:
       github: ettomatic/xattr
   

2. Run shards install

Usage

require "xattr"

xattr = XAttr.new("./myfile.txt")
xattr["tags"] = "mytag1,mytag2"
xattr["tags"]
# => "mytag1,mytag2"

xattr.keys
# => ["tags"]

xattr.to_h
# => { "tags" => "mytag1,mytag2" }

xattr.remove("tags")
xattr.keys
