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 v0.11.0, libprism v1.9.0, libherb v0.11.0 (Ruby C native extension)"

JavaScript

Herb.version
// => "@herb-tools/node@0.11.0, @herb-tools/core@0.11.0, libherb@0.11.0 (Node.js C++ native extension)"

Java

Herb.version();
// => "herb java v0.11.0, libprism v1.9.0, libherb v0.11.0 (Java JNI)"

Rust

herb::version();
// => "herb rust v0.11.0, libprism v1.9.0, libherb v0.11.0 (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();   // => "0.11.0"
Herb.prismVersion();  // => "1.9.0"

Rust

herb::herb_version();   // => "0.11.0"
herb::prism_version();  // => "1.9.0"

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

bundle exec herb version
