Versions

Every binding reports the version of itself, of the C library it wraps and of the Prism it parses Ruby with. A bug report is much easier to act on with this line in it.

Ruby

Herb.version
# => "herb gem v0.11.2, libprism v2.1.0+4691667, libherb v0.11.2 (Ruby C native extension)"

JavaScript

Herb.version
// => "@herb-tools/node@0.11.2, @herb-tools/core@0.11.2, libprism@2.1.0+4691667, libherb@0.11.2 (Node.js C++ native extension)"

Java

Herb.version();
// => "herb java v0.11.2, libprism v2.1.0+4691667, libherb v0.11.2 (Java JNI)"

Rust

herb::version();
// => "herb rust v0.11.2, libprism v2.1.0+4691667, libherb v0.11.2 (Rust FFI)"

Java and Rust also report the two versions on their own, which is the form to compare against in code.

Java

Herb.herbVersion();   // => "0.11.2"
Herb.prismVersion();  // => "2.1.0+4691667"

Rust

herb::herb_version();   // => "0.11.2"
herb::prism_version();  // => "2.1.0+4691667"

The herb version command prints the same information for the gem and the library it loaded.

bundle exec herb version
