- Add PolicyLengthConfig struct with max_col, max_file_bytes, and max_lines fields, replacing hardcoded constants in the lexer. - Add Engine::set_policy_length_config and clear_policy_length_config to allow callers to override the default limits. - Add Source::from_contents_with_limits and from_file_with_limits for direct Source construction with custom limits; existing from_contents and from_file signatures are preserved using defaults. - Add tests for default rejection, custom limits, and engine plumbing. - Add bindings for C, C++, Python, WASM/JS, Java, Ruby, C#, Go
Regorusrb
Regorus is
- Rego-Rus(t) - A fast, light-weight Rego interpreter written in Rust.
- Rigorous - A rigorous enforcer of well-defined Rego semantics.
Installation
Regorus can be used in Ruby by configuring bundler to build from the remote git source.
If using Bundler to manage gems (recommended), edit your gemfile to include the following
gem "regorusrb", git: "https://github.com/microsoft/regorus/", glob: "bindings/ruby/*.gemspec"
or manually install checkout the source and build the gem
git clone https://github.com/microsoft/regorus/ cd regorus/bindings/ruby rake && rake build # should eventually output 'regorusrb 0.1.0 built to pkg/regorusrb-0.1.0.gem.' gem install --local ./pkg/regorusrb-0.1.0.gem
It is not yet available in rubygems.
See Repository.
To build this gem locally without bundler,
rake build
then to install the gem and build the native extensions
gem install --local ./pkg/regorusrb-0.1.0.gem

Development
To update the gem version or dependencies within bindings/ruby/Gemfile.lock, run bundle update --gemfile=bindings/ruby/Gemfile from the project directory, or cd bindings/ruby && bundle update
After checking out the repo, cd bindings/ruby and run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
