Streem is a stream based concurrent scripting language. It is based on a programming model similar to the shell, with influences from Ruby, Erlang, and other functional programming languages.
Note: Streem is still in the design stage. It's not working yet. Stay tuned.
In Streem, a simple cat program looks like this:
STDIN | STDOUT
Streem is a (sort of) DSL for data flows. Above code means
building data-flow connection between STDIN and STDOUT.
Actual data processing will be done in the event loop
invoked after program execution.
For another example, a simple FizzBuzz will look like this:
seq(100) | {|x|
if x % 15 == 0 {
"FizzBuzz"
}
else if x % 3 == 0 {
"Fizz"
}
else if x % 5 == 0 {
"Buzz"
}
else {
x
}
} | STDOUT
The second part in the pipeline ({|x|...}) is a function
object. If a function object is connected in the pipeline,
it will be invoked for each element in the stream.

- gcc / clang
make
Please note that Streem will not run any scripts yet, but you can check parse files and check syntax.
