# Deno Shell

Deno Shell is a experimental TypeScript shell that's very thin layer on top of Deno.

DenoSH scripts is superset of TypeScript so any typescript code should work just fine.

# Features

- [ ] first class executables

- [ ] piping function output into variables

# Areas to explore

- structured output

- concurrency (execute binaries with something like `await Promise.all([$(echo one), $(echo two)])`)

- queue command while another command is running

# Non goals

- performance (who cares - it's shell)

# Syntax rules

- ?

# Examples (not implemented)

### Saving output of command

```js

let x = $(echo test message);

console.log(x); // outputs `test message`

```

### Parallelize execution

```js

const results = await Promise.all([$(sleep 10), $(sleep 15), $(sleep 20)]);

// Will sleep for 20sec

```

### JSON support

```js

let z = $(curl http://some-json.com/json);

console.log(z.nested.field); // returned json was changed into json without user action

```

### String interpoloration

```js

let z = "Some string";

echo ${z}

let url = "http://some-json.com/json";

curl ${url} | echo

```

### Error codes?

I'd like something like this to work

```js

fallibleCommand;

// if command fails, error will be printed out

```

```js

try {

  fallibleCommand;

} catch (e) {

  // if command fails, user has access to error inside `e` variable

  // e: {code: 123, text: "error text"}

}

```
