Position Independent Source Code

This repository is a mirror of [pisc.junglecoder.com](https://pisc.junglecoder.com), so if you'd like to get the best view of the project, that's where you should be able to find it.
I recommend opening an issue, or emailing me based on my profile before opening a PR. 

Right now I'm focusing on more tests, some basic performance improvements, and building up to a high quality IRC/Slack/Discord chat-bot frame work, hopefully one that can trade punches with Hubot. Contributions that focus in theses areas are more than welcome.

# PISC
Position Independent Source Code. A small, stack-based, concatenative language.

## About 

This is currently a small side project to see how far a small stack-based scripting language can go in spare time. Inspired by Factor (80%), Forth (5%) and Python (5%) and Tcl (5%) (not 100% inspired yet.)
Plans are currently for an interperated language that uses a "arrays and hashtables" approach to data stucturing.

## TODO:

If you can understand what is going on, please submit a pull request to add something that I'm missing. I'm not trying to compete with [factor](http://factorcode.org) or [forth](http://www.forth.com/forth/) for performance/features, but I trying out their style of programming to see how it goes. Ports of this interpretor to the language of your choice are welcome as well. 

With that in mind, things that I will be adding (or accepting PRs for) as [time](http://www.catb.org/jargon/html/C/copious-free-time.html) allows:


  - More tests for different combinators (if, loop, while)
  - A standard library build from a minimal core (this is a lot of the things below)
  - Stack shuffling combinators (see the ones in factor):

  -- drop ( x -- )
  -- 2drop ( x y -- )

  -- 3drop ( x y z -- )
  -- nip ( x y -- y )
  -- 2nip ( x y z -- z )
  -- dup  ( x -- x x )
  -- 2dup ( x y -- x y x y )
  -- 3dup ( x y z -- x y z )
  -- 2over ( x y z -- x y z x y )
  -- pick ( x y z -- x y z x )
  -- swap ( x y -- y x )
  - Add a way for modules to be added without a lot of major modifications in the core loop of the interp.
  - Math words. A lot is needed here, and in double/int versions ( >, <, =, -, +, div, mod ) 
  - String manipulation words (concat, >upper, >lower, int>string, double>string, etc)
  - Array and map manipulating words (ways to define them, literals, member access, so on.)
  - A basic compliation step for reducing cache misses in the core loop (transforming words into constant lookup codes, so that word lookup isn't proportional to the number of words in the core loop)
  - STDIN/STDOUT words.
  - Regex facilties. 
  - File i/o words
  - A plan for multiprocessing. (I want to pull from TCL on this one if I can)
  - Combinators for quotations, like bi and tri. 
  - A plan for a module system.
  - Syscalls
  - shellout words. 
  - struct words (when this thing allows for partial compilation or some such thing.)
  - Bindings to awesome libraries (SDL, Tk, ImageMagick)

# PISC
Position Independent Source Code. A small, stack-based, concatenative language.

## About 

PISC's source and documentation are hosted at [https://pisc.junglecoder.com/ ](https://pisc.junglecoder.com).
A quick starter can be found at [PISC in Y Minutes](https://pisc.junglecoder.com/home/apps/fossil/PISC.fossil/wiki?name=PISC+in+Y+Minutes)

## Building 

PISC requires go 1.9+ to build. Installation instructions [here](https://golang.org/doc/install)

Once go is installed, you'll (currently) need to run `git clone https://github.com/yumaikas/PISC-mirror "$GOPATH/src/pisc"`
Running `cd $GOPATH/src/pisc && go get -u && go build -o pisc` will fetch depenencies and get you a PISC executable. You can launch a REPL with `pisc -i` and play with it there.


## Playground


PISC has a playground at https://pisc.junglecoder.com/playground/

Explorers are even now mapping out the various lanes of slipspace. Most people seem to be content to stay on the planet of their birth, as both subspace and slipspace are treacherous places. Pirates, freighters, and smugglers alike vie for fattest, quickest buck. Planetary fleets mostly protect their homes. There used to be a system-wise empire around Sol, but logistics makes a galaxy-wide one near-impossible. Even if galactic rule was possible, the early slipspace instabilities spread people far and wide throughout space. This factured the society left behind. It took decades for a slipspace drive to be stable enough for more experimental use. It was only with the aging and death of those who witnessed the slipspace fracturing that the slipspace came to be accepted as a means of travel. The last 15 years have shown wondrous things.

/*
Each ship is built out of lanes
Each ship has a drone loadout controlled by the Cockpit
If the cockpit is destroyed, you game is over. 
Most ships don't try to destroy a cockpit however, 
preferring to leave you helpless or capture you.

Ships can have 1x3 to 3x10 in dimentions, and filled with different segments

Lanes can come in 3 sizes as well, Small, Medim and Large

Segment types (* indicate mandatory segment): 

Life-support/Cockpit*, 
Engines*,
Fuel Tank*
cargo pod
Crew quarter (1 crew member per section)
drone pod (1 drone per section)

There are also possible non-standard segments:

Long range sensors ( extra combat round )
Contraband pod ( far better chance of passing an inspection )
Ship scanner (allows you to see into ship segments)
Tow package (allows you to haul ships/trailers around)

Segments have varying levels of armor:
low: Can be breached by any attck
medium: Will withstand a minimum of 1 successful attack.
heavy: Will withstand a minimum of 3 successful attacks.

Drones come in 3 basic types:

Attack: Shoots stuff
Defence: Defends against attack drones, each shot charges up a mega-beam
Ion: shorts-out drones and/or sections

Advanced drones: Raider

Raider drones do a variety of things, depending on which type of segment they manage to hit

If they hit Life-support/cockpit, they take over the ship, 
which allows it to be slaved to yours for transport to shipyards

If they hit a engine pod, the opposing ship will be slowed down

If they hit a Fuel tank, all the fuel in that tank is transfered to your ship next turn

If they hit a cargo bay, the cargo in that bay is transfared to your ship next turn

If they hit a crew-quarter, the crew member in that quarter is either 
captured or killed, depending on if you have space to carry them or not.

# It's AJAX

All over again. Includes support for xmlHttpRequest, JSONP, CORS, and CommonJS Promises A.

It is also isomorphic allowing you to `require('reqwest')` in `Node.js` through the peer dependency [xhr2](https://github.com/pwnall/node-xhr2), albeit the original intent of this library is for the browser. For a more thorough solution for Node.js, see [mikeal/request](https://github.com/request/request).

## API

``` js
reqwest('path/to/html', function (resp) {
  qwery('#content').html(resp)
})

reqwest({
    url: 'path/to/html'
  , method: 'post'
  , data: { foo: 'bar', baz: 100 }
  , success: function (resp) {
      qwery('#content').html(resp)
    }
})

reqwest({
    url: 'path/to/html'
  , method: 'get'
  , data: [ { name: 'foo', value: 'bar' }, { name: 'baz', value: 100 } ]
  , success: function (resp) {
      qwery('#content').html(resp)
    }
})

reqwest({
    url: 'path/to/json'
  , type: 'json'
  , method: 'post'
  , error: function (err) { }
  , success: function (resp) {
      qwery('#content').html(resp.content)
    }
})

reqwest({
    url: 'path/to/json'
  , type: 'json'
  , method: 'post'
  , contentType: 'application/json'
  , headers: {
      'X-My-Custom-Header': 'SomethingImportant'
    }
  , error: function (err) { }
  , success: function (resp) {
      qwery('#content').html(resp.content)
    }
})

// Uses XMLHttpRequest2 credentialled requests (cookies, HTTP basic auth) if supported
reqwest({
    url: 'path/to/json'
  , type: 'json'
  , method: 'post'
  , contentType: 'application/json'
  , crossOrigin: true
  , withCredentials: true
  , error: function (err) { }
  , success: function (resp) {
      qwery('#content').html(resp.content)
    }
})

reqwest({
    url: 'path/to/data.jsonp?callback=?'
  , type: 'jsonp'
  , success: function (resp) {
      qwery('#content').html(resp.content)
    }
})

reqwest({
    url: 'path/to/data.jsonp?foo=bar'
  , type: 'jsonp'
  , jsonpCallback: 'foo'
  , jsonpCallbackName: 'bar'
  , success: function (resp) {
      qwery('#content').html(resp.content)
    }
})

reqwest({
    url: 'path/to/data.jsonp?foo=bar'
  , type: 'jsonp'
  , jsonpCallback: 'foo'
  , success: function (resp) {
      qwery('#content').html(resp.content)
    }
  , complete: function (resp) {
      qwery('#hide-this').hide()
    }
})
```

## Promises

``` js
reqwest({
    url: 'path/to/data.jsonp?foo=bar'
  , type: 'jsonp'
  , jsonpCallback: 'foo'
})
  .then(function (resp) {
    qwery('#content').html(resp.content)
  }, function (err, msg) {
    qwery('#errors').html(msg)
  })
  .always(function (resp) {
    qwery('#hide-this').hide()
  })
```

``` js
reqwest({
    url: 'path/to/data.jsonp?foo=bar'
  , type: 'jsonp'
  , jsonpCallback: 'foo'
})
  .then(function (resp) {
    qwery('#content').html(resp.content)
  })
  .fail(function (err, msg) {
    qwery('#errors').html(msg)
  })
  .always(function (resp) {
    qwery('#hide-this').hide()
  })
```

``` js
var r = reqwest({
    url: 'path/to/data.jsonp?foo=bar'
  , type: 'jsonp'
  , jsonpCallback: 'foo'
  , success: function () {
      setTimeout(function () {
        r
          .then(function (resp) {
            qwery('#content').html(resp.content)
          }, function (err) { })
          .always(function (resp) {
             qwery('#hide-this').hide()
          })
      }, 15)
    }
})
```

## Options

  * `url` a fully qualified uri
  * `method` http method (default: `GET`)
  * `headers` http headers (default: `{}`)
  * `data` entity body for `PATCH`, `POST` and `PUT` requests. Must be a query `String` or `JSON` object
  * `type` a string enum. `html`, `xml`, `json`, or `jsonp`. Default is inferred by resource extension. Eg: `.json` will set `type` to `json`. `.xml` to `xml` etc.
  * `contentType` sets the `Content-Type` of the request. Eg: `application/json`
  * `crossOrigin` for cross-origin requests for browsers that support this feature.
  * `success` A function called when the request successfully completes
  * `error` A function called when the request fails.
  * `complete` A function called whether the request is a success or failure. Always called when complete.
  * `jsonpCallback` Specify the callback function name for a `JSONP` request. This value will be used instead of the random (but recommended) name automatically generated by reqwest.

## Security

If you are *still* requiring support for IE6/IE7, consider including [JSON3](https://bestiejs.github.io/json3/) in your project. Or simply do the following

``` html
<script>
(function () {
  if (!window.JSON) {
    document.write('<scr' + 'ipt src="http://cdnjs.cloudflare.com/ajax/libs/json3/3.3.2/json3.min.js"><\/scr' + 'ipt>')
  }
}());
</script>
```


## Contributing

``` sh
$ git clone git://github.com/ded/reqwest.git reqwest
$ cd !$
$ npm install
```

Please keep your local edits to `src/reqwest.js`.
The base `./reqwest.js` and `./reqwest.min.js` will be built upon releases.

## Running Tests

``` sh
make test
```

## Browser support

  * IE6+
  * Chrome 1+
  * Safari 3+
  * Firefox 1+
  * Opera

## Ender Support
Reqwest can be used as an [Ender](http://enderjs.com) module. Add it to your existing build as such:

    $ ender add reqwest

Use it as such:

``` js
$.ajax({ ... })
```

Serialize things:

``` js
$(form).serialize() // returns query string -> x=y&...
$(form).serialize({type:'array'}) // returns array name/value pairs -> [ { name: x, value: y}, ... ]
$(form).serialize({type:'map'}) // returns an object representation -> { x: y, ... }
$(form).serializeArray()
$.toQueryString({
    foo: 'bar'
  , baz: 'thunk'
}) // returns query string -> foo=bar&baz=thunk
```

Or, get a bit fancy:

``` js
$('#myform input[name=myradios]').serialize({type:'map'})['myradios'] // get the selected value
$('input[type=text],#specialthing').serialize() // turn any arbitrary set of form elements into a query string
```

## ajaxSetup
Use the `request.ajaxSetup` to predefine a data filter on all requests. See the example below that demonstrates JSON hijacking prevention:

``` js
$.ajaxSetup({
  dataFilter: function (response, type) {
    if (type == 'json') return response.substring('])}while(1);</x>'.length)
    else return response
  }
})
```

## RequireJs and Jam
Reqwest can also be used with RequireJs and can be installed via jam

```
jam install reqwest
```

```js
define(function(require){
  var reqwest = require('reqwest')
});
```

## spm
Reqwest can also be installed via spm [![](http://spmjs.io/badge/reqwest)](http://spmjs.io/package/reqwest)

```
spm install reqwest
```

## jQuery and Zepto Compatibility
There are some differences between the *Reqwest way* and the
*jQuery/Zepto way*.

### method ###
jQuery/Zepto use `type` to specify the request method while Reqwest uses
`method` and reserves `type` for the response data type.

### dataType ###
When using jQuery/Zepto you use the `dataType` option to specify the type
of data to expect from the server, Reqwest uses `type`. jQuery also can
also take a space-separated list of data types to specify the request,
response and response-conversion types but Reqwest uses the `type`
parameter to infer the response type and leaves conversion up to you.

### JSONP ###
Reqwest also takes optional `jsonpCallback` and `jsonpCallbackName`
options to specify the callback query-string key and the callback function
name respectively while jQuery uses `jsonp` and `jsonpCallback` for
these same options.


But fear not! If you must work the jQuery/Zepto way then Reqwest has
a wrapper that will remap these options for you:

```js
reqwest.compat({
    url: 'path/to/data.jsonp?foo=bar'
  , dataType: 'jsonp'
  , jsonp: 'foo'
  , jsonpCallback: 'bar'
  , success: function (resp) {
      qwery('#content').html(resp.content)
    }
})

// or from Ender:

$.ajax.compat({
  ...
})
```

If you want to install jQuery/Zepto compatibility mode as the default
then simply place this snippet at the top of your code:

```js
$.ajax.compat && $.ender({ ajax: $.ajax.compat });
```


**Happy Ajaxing!**
