Easier: install it from the Store, which also updates it.
This app provides Ruby - ruby, gem, bundle, irb, rake and the other commands that come with it - to run and build Ruby programs directly on the WD NAS device.
- Its standard library is complete: OpenSSL (
openssl,net/https), YAML (psych, with libyaml),fiddle(libffi) andzlibare built in, as are the gems that come with Ruby (Bundler, Rake, Minitest, test-unit, RBS, TypeProf, debug, RDoc...). The NAS's own libraries aren't used, so nothing depends on their versions. - Gems you install are kept when the app is updated or removed: they go in
Nas_Prog/_ruby/gems, and their commands inNas_Prog/_ruby/bin, linked into/usr/bin(as root - never over a command that's already there; the app links them again at every boot).bundle installworks the same way, and a project can still keep its gems in its own folder (bundle config set --local path vendor/bundle). - No C compiler on the NAS: gems that come ready-built for Linux install as usual (e.g.
sqlite3,nokogiri,pg,ffi,google-protobuf), and pure Ruby gems always do. A gem that has to compile C code needs a compiler - e.g. the Entware app's (opkg install gcc make). Ruby's own headers are included, for that. - HTTPS works (
gem install,Net::HTTP): Ruby's OpenSSL trusts the app's own copy of Mozilla's certificate authorities (binaries/etc/cacert.pem, as curl publishes it), unlessSSL_CERT_FILEorSSL_CERT_DIRsays otherwise. - It's Ruby built from its source on the NAS's Debian version (so it only needs the NAS's own glibc), relocatable, and pinned by SHA256 with its libraries in
static/ruby/build.sh. The app's RubyGems settings are instatic/ruby/operating_system.rb. Intel models only.
A small test server is started on port 30291 (a page with Ruby's and its libraries' versions), with its output in test_server.log in the app's install directory.
The app's page in the NAS dashboard (Apps → Ruby) shows the versions of Ruby, RubyGems and Bundler, the gems installed, and the test server's status, with a link to it and a restart button. Only NAS admins can use the page (see Management pages).
