This is a [Racket](http://racket-lang.org/) package containing a
|
|
|
|
|
single
|
|
|
|
|
[collection](http://docs.racket-lang.org/reference/collects.html),
|
|
|
|
|
`marketplace`, which includes
|
|
|
|
|
|
|
|
|
|
- the implementation of the `#lang marketplace` language from the
|
|
|
|
|
paper, in
|
|
|
|
|
[`marketplace/`](https://github.com/tonyg/marketplace/tree/master/marketplace/).
|
|
|
|
|
|
|
|
|
|
- the echo server example from the paper, in

|
|
|
[`marketplace/examples/echo-paper.rkt`](https://github.com/tonyg/marketplace/tree/master/marketplace/examples/echo-paper.rkt).

|
|
|

[`marketplace/examples/chat-paper.rkt`](https://github.com/tonyg/marketplace/tree/master/marketplace/examples/chat-paper.rkt).
|
|
|
|
|
|
|
|
|
|
- the Haskell, Erlang and Python implementations of the chat server
|
|
|
|
|
from the paper, in

[`marketplace/examples/chat.hs`](https://github.com/tonyg/marketplace/tree/master/marketplace/examples/chat.hs),

[`chat.erl`](https://github.com/tonyg/marketplace/tree/master/marketplace/examples/chat.erl),

and

[`chat.py`](https://github.com/tonyg/marketplace/tree/master/marketplace/examples/chat.py)

respectively.

## How to compile and run the code
|
|
|
|
|
|
|
|
|
|
You will need the latest **prerelease** version of Racket. Any version
|
|
|
|
|
newer than or equal to Racket 5.3.3.7 should work. Nightly-build
|
|
|
|
|
installers for Racket can be downloaded
|
|
|
|
|
[here](http://pre.racket-lang.org/installers/).
|
|
|
|

|
|
|
Once you have Racket installed, run
|
|
|
|
|
|
|
|
|
|
raco pkg install --link `pwd`
|
|
|
|
|
|
|
|
|
|
from the root directory of the Git checkout to install the package in
|
|
|
|
|
your Racket system. (Alternatively, `make link` does the same thing.)
|
|
|
|
|
This will make `#lang marketplace` available to programs.
|
|
|
|
|
|
|
|
|
|
It will take several minutes to compile the code. On my Macbook Air,
|
|
|
|
|
it takes around 10 minutes; on my ridiculously fast desktop machine,
|
|
|
|
|
it still takes around 2 minutes.

|
|
|
|
|
|
|
|
At this point, you may load and run any of the example `*.rkt` files
|
|
|
|
|
in the
|
|
|
|
|
[`marketplace/examples/`](https://github.com/tonyg/marketplace/tree/master/marketplace/examples/)
|
|
|
|
|
directory.
|
|
|
|
|
|
|
|
|
|
Note that both the echo server and chat server examples do not print
|
|
|
|
|
any output on standard output: instead, they simply start running and
|
|
|
|
|
silently await TCP connections. Once one of the servers is running, in
|
|
|
|
|
a separate window, try `telnet localhost 5999`.
|
|
|
|
|
|
|
|
|
|
Note also that both the echo server and the chat server use port 5999,
|
|
|
|
|
so you cannot run both simultaneously.
