-# aesophia
-
-This is the __sophia__ compiler for the æternity system which compiles contracts written in __sophia__ code to the æternity VM code.
-
-For more information about æternity smart contracts and the sophia language see [Smart Contracts](https://github.com/aeternity/protocol/blob/master/contracts/contracts.md) and the [Sophia Language](https://github.com/aeternity/protocol/blob/master/contracts/sophia.md).
-
-It is an OTP application written in Erlang and is by default included in
-[æternity Epoch](https://github.com/aeternity/epoch). However, it can
-also be included in other system to compile contracts coded in sophia which
-can then be loaded into the æternity system.

+<p>The ACI interface encoder and decoder.</p>
+<h3 id="description">Description</h3>
+<p>This module provides an interface to generate and convert between
+Sophia contracts and a suitable JSON encoding of contract
+interface. As yet the interface is very basic.</p>
+<p>Encoding this contract:</p>
+<div class="highlight"><pre><span></span><code>contract Answers =
+  record state = { a : answers }
+  type answers() = map(string, int)
+
+  stateful function init() = { a = {} }
+  private function the_answer() = 42
+  function new_answer(q : string, a : int) : answers() = { [q] = a }
+</code></pre></div>
+<p>generates the following JSON structure representing the contract interface:</p>
+<div class="highlight"><pre><span></span><code><span class="p">{</span>
+<span class="w">  </span><span class="nt">&quot;contract&quot;</span><span class="p">:</span><span class="w"> </span><span class="p">{</span>

+<p>Sophia is a functional language designed for smart contract development. It is strongly typed and has
+restricted mutable state.</p>
+<p>Sophia is customized for smart contracts, which can be published
+to a blockchain. Thus some features of conventional
+languages, such as floating point arithmetic, are not present in Sophia, and
+some <a href="https://aeternity.com">æternity blockchain</a> specific primitives, constructions and types have been added.</p>

+<h2 id="layout-blocks">Layout blocks</h2>
+<p>Sophia uses Python-style layout rules to group declarations and statements. A
+layout block with more than one element must start on a separate line and be
+indented more than the currently enclosing layout block. Blocks with a single
+element can be written on the same line as the previous token.</p>
+<p>Each element of the block must share the same indentation and no part of an
+element may be indented less than the indentation of the block. For instance</p>
+<div class="highlight"><pre><span></span><code><span class="k">contract</span><span class="w"> </span><span class="nf">Layout</span><span class="w"> </span><span class="ow">=</span>

+</code></pre></div>
+<h2 id="notation">Notation</h2>
+<p>In describing the syntax below, we use the following conventions:</p>
+<ul>
+<li>Upper-case identifiers denote non-terminals (like <code>Expr</code>) or terminals with
+  some associated value (like <code>Id</code>).</li>
+<li>Keywords and symbols are enclosed in single quotes: <code>'let'</code> or <code>'='</code>.</li>
+<li>Choices are separated by vertical bars: <code>|</code>.</li>
+<li>Optional elements are enclosed in <code>[</code> square brackets <code>]</code>.</li>
+<li><code>(</code> Parentheses <code>)</code> are used for grouping.</li>
+<li>Zero or more repetitions are denoted by a postfix <code>*</code>, and one or more
+  repetitions by a <code>+</code>.</li>
+<li><code>Block(X)</code> denotes a layout block of <code>X</code>s.</li>
+<li><code>Sep(X, S)</code> is short for <code>[X (S X)*]</code>, i.e. a possibly empty sequence of <code>X</code>s
+  separated by <code>S</code>s.</li>
+<li><code>Sep1(X, S)</code> is short for <code>X (S X)*</code>, i.e. same as <code>Sep</code>, but must not be empty.</li>
+</ul>
+<h2 id="declarations">Declarations</h2>
+<p>A Sophia file consists of a sequence of <em>declarations</em> in a layout block.</p>

-%% Jump optimization:
-%%   Replaces a jump to a jump with a jump to the final destination

-
-%% The compilation of conditionals generates a lot of labels and
-%% jumps, some of them unnecessary. This optimization phase reorders
-%% code so that as many jumps as possible can be eliminated, and
-%% replaced by just falling through to the destination label. This
-%% both optimizes the code generated by conditionals, and converts one
-%% call of a function into falling through into its code--so it
-%% reorders code quite aggressively. Function returns are indirect
-%% jumps, however, and are never optimized away.
-
-%% IMPORTANT: since execution begins at address zero, then the first
-%% block of code must never be moved elsewhere. The code below has
-%% this property, because it processes blocks from left to right, and
-%% because the first block does not begin with a label, and so can
-%% never be jumped to--hence no code can be inserted before it.
-
-%% The optimization works by taking one block of code at a time, and
-%% then prepending blocks that jump directly to it, and appending
-%% blocks that it jumps directly to, resulting in a jump-free sequence
-%% that is as long as possible. To do so, we store blocks in the form
-%% {OptionalLabel, Body, OptionalJump} which represents the code block
-%% OptionalLabel++Body++OptionalJump; the optional parts are the empty
-%% list of instructions if not present.  Two blocks can be merged if
-%% the first ends in an OptionalJump to the OptionalLabel beginning
-%% the second; the OptionalJump can then be removed (and the
-%% OptionalLabel if there are no other references to it--this happens
-%% during dead code elimination.
-
-%% TODO: the present implementation is QUADRATIC, because we search
-%% repeatedly for matching blocks to merge with the first one, storing
