# Streem

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.
## Compiling
### Installing dependencies
* bison
* flex
* gcc / clang
### Run make
```shell
make
```
## Examples
In Streem, a simple `cat` program looks like this:
```
stdin | stdout
```
You can try it out by (firstly `cd` to streem top directory):
```shell
$ bin/streem -e 'stdin | stdout'
```
or
```shell
$ bin/streem examples/01cat.strm
```
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) returns a stream of numbers from 1 to 100.
# A function object in pipeline works as a map function.
# stdout is an output destination.
seq(100) | map{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.
There are more examples under folder `examples/`. Just play with them!
