Streem is a prototype of a stream-based concurrent scripting language created by Yukihiro Matsumoto, influenced by the shell pipeline model, Ruby, and Erlang. It is implemented in C and provides a CLI interpreter where programs are expressed as data-flow pipelines such as 'stdin | stdout'.

Use cases

  • write shell-like pipeline scripts
  • experiment with stream-based programming
  • process data flows concurrently
  • learn about concurrent language design
  • run simple data transformation pipelines

When to choose

  • you want to experiment with a novel stream-oriented language design
  • you are interested in pipeline/concurrency language research
  • you want a lightweight C-based scripting interpreter to hack on

When to avoid

  • you need a production-ready language - it is explicitly still in the design stage
  • you need a rich standard library or ecosystem
  • you need long-term stability or support
