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
