# Pyramid Scheme
Pyramid is a dialect of the Scheme programming language targeting the Ethereum Virtual Machine(EVM).
Here is an example of a Pyramid program:
```scheme
(begin
(define (factorial n)
(if (= n 1)
1
(* (factorial (- n 1)) n)))
(factorial 5))
```
## Getting Started
Pyramid Scheme is under heavy construction. Join our [public Discord channel](https://discord.gg/854RH6x) if you'd like to contribute or use Pyramid to develop Ethereum contracts.
After installing the prerequisites(listed below),
```bash
$ ./pyramid -t tests/0001-factorial.pmd
(Test Passed: return 120 120 ((s . 14066) (g . 47052) (z . 3591)))
```
To deploy that program on a test network:
* Install [Ganache CLI](https://github.com/trufflesuite/ganache-cli)
* Start an EthereumJS test chain: `ganache-cli -l 10000000`. It will output a list of "Available Accounts".
* Change the `from` variable in [deploy.js](deploy.js) to one of the test accounts.
* Change the `code` variable to be the hex string that the Pyramid compiler output
* Install the [Go Ethereum](https://github.com/ethereum/go-ethereum) client.
* Attach to the EthereumJS chain: `geth attach http://localhost:8545`.
* Copy the contents of `deploy.js` into the `geth` Javascript prompt.
You can see advanced command line options using `pyramid --help`.
### Prerequisites
* Install the Racket language runtime at https://download.racket-lang.org
* Install necessary packages using "raco pkg install ". The packages are:
* [binaryio-lib](https://docs.racket-lang.org/binaryio/index.html)
* [errortrace-lib](https://docs.racket-lang.org/errortrace/using-errortrace.html)
* Ensure the `keccak-256sum` tool is available on your PATH

### Editor
I recommend Emacs with `racket-mode`. You should add Pyramid's `.pmd` extension to the list of `racket-mode` file extensions:
```
(add-to-list 'auto-mode-alist '("\\.pmd\\'" . racket-mode))
```
