# solc-ast

[![Pypi Status](https://img.shields.io/pypi/v/py-solc-ast.svg)](https://pypi.org/project/py-solc-ast/) [![Build Status](https://img.shields.io/github/workflow/status/iamdefinitelyahuman/py-solc-ast/main%20workflow/master)](https://github.com/iamdefinitelyahuman/py-solc-ast/actions) [![Coverage Status](https://img.shields.io/codecov/c/github/iamdefinitelyahuman/py-solc-ast)](https://codecov.io/gh/iamdefinitelyahuman/py-solc-ast)

A tool for exploring the Solidity abstrax syntrax tree as generated by the [solc](https://github.com/ethereum/solidity) compiler.

## Installation

You can install the latest release via `pip`:

```bash
$ pip install py-solc-ast
```

Or clone the repo and use `setuptools`:

```bash
$ python setup.py install
```

## Usage

First, use [py-solc-x](https://github.com/iamdefinitelyahuman/py-solc-x) to compile your contracts to the [standard JSON output format](https://solidity.readthedocs.io/en/latest/using-the-compiler.html#output-description).

```python
>>> import json
>>> import solcx
>>> input_json = json.load(open('input.json'))
>>> output_json = solcx.compile_standard(input_json)
```

Next, import `solcast` and initialize using `from_standard_output_json` or `from_standard_output`. This returns a list of `SourceUnit` objects, which each represent the base AST node in a Solidity source file.

```python
>>> import solcast
>>> nodes = solcast.from_standard_output(output_json)
>>> nodes
[<SourceUnit iterable 'contracts/Token.sol'>, <SourceUnit iterable 'contracts/SafeMath.sol'>]
```

You can also generate a single `SourceUnit` directly from that source's AST:

```python
>>> import solcast
>>> node = solcast.from_ast(output_json["sources"]["contracts/Token.sol"]["ast"])
>>> node
<SourceUnit iterable 'contracts/Token.sol'>
```

### Interacting with Nodes

Each node has the following attributes:

```python
>>> node
<FunctionDefinition iterable 'mul'>

>>> node.depth  # Number of nodes between this node and the SourceUnit
2

>>> node.offset  # Absolute source offsets as a (start, stop) tuple
(1693, 2151)

>>> node.contract_id  # Contract ID as given by the standard compiler JSON
2

>>> node.fields  # List of fields for this node
['baseNodeType', 'documentation', 'id', 'implemented', 'kind', 'modifiers', 'name', 'nodeType', 'nodes', 'parameters', 'returnParameters', 'scope', 'src', 'stateMutability', 'superFunction', 'visibility']

```

Fields mostly follow the expected [AST grammar](https://solidity.readthedocs.io/en/latest/miscellaneous.html#language-grammar). One notable difference: `Block` nodes are omitted and the body of each `Block` is available within it's parent as the attribute `nodes`. Nodes containing a body are iterable and can be accessed with list-like syntax. Additionally, any child node with a `name` field is accessible using dict-like syntax.

The following additional fields are also available:

* Most nodes have a `baseNodeType` field as defined in [grammar.py](solcast/grammar.py)
* `ContractDefinition` nodes have `dependencies` and `libraries` fields that point to related `ContractDefition` nodes

Some Examples:

```python
>>> source_node
<SourceUnit iterable 'contracts/math/SafeMath.sol'>

>>> source_node.keys()
['absolutePath', 'children', 'contract_id', 'depth', 'exportedSymbols', 'id', 'is_child_of', 'is_parent_of', 'keys', 'nodeType', 'nodes', 'offset', 'parent', 'parents', 'src']

>>> source_node.nodes
[<PragmaDirective object>, <ContractDefinition iterable 'SafeMath'>]

>>> source_node[1]
<ContractDefinition iterable 'SafeMath'>

>>> source_node['SafeMath']
<ContractDefinition iterable 'SafeMath'>

>>> source_node['SafeMath'].keys()
['baseContracts', 'children', 'contractDependencies', 'contractKind', 'contract_id', 'dependencies', 'depth', 'documentation', 'fullyImplemented', 'id', 'is_child_of', 'is_parent_of', 'keys', 'libraries', 'linearizedBaseContracts', 'name', 'nodeType', 'nodes', 'offset', 'parent', 'parents', 'scope', 'src']

>>> source_node['SafeMath'].nodes
[<FunctionDefinition iterable 'add'>, <FunctionDefinition iterable 'sub'>, <FunctionDefinition iterable 'mul'>, <FunctionDefinition iterable 'div'>, <FunctionDefinition iterable 'mod'>]

>>> source_node['SafeMath']['mul']
<FunctionDefinition iterable 'mul'>

>>> source_node['SafeMath']['mul']
[<IfStatement object>, <VariableDeclarationStatement object>, <FunctionCall object>, <Return object>]
```

### Exploring the Tree

The `Node.children()` method is used to search and filter through child nodes of a given node. It takes any of the following keyword arguments:

* `depth`: Number of levels of children to traverse. `0` returns only this node.
* `include_self`: Includes this node in the results.
* `include_parents`: Includes nodes that match in the results, when they also have child nodes that match.
* `include_children`: If True, as soon as a match is found it's children will not be included in the search.
* `required_offset`: Only match nodes with a source offset that contains this offset.
* `offset_limits`: Only match nodes when their source offset is contained inside this source offset.
* `filters`: Dictionary of `{'attribute': "value"}` that children must match. Can also be given as a list of dicts, children that match any of the dicts will be returned.
* `exclude_filter`: Dictionary of `{'attribute': "value"}` that children cannot match.

```python
>>> node = s['Token']['transfer']
>>> node.children(
    include_children=False,
    filters={'nodeType': "FunctionCall", "expression.name": "require"}
)
[<FunctionCall>]
```

`Node.parent()` and `Node.parents()` are used to travel back up the tree. They take the following arguments:

* `depth`: Depth limit. If given as a negative value, it will be subtracted from this object's depth.
* `filters`: Dictionary of `{'attribute': "value"}` that parents must match.

`Node.parent()` returns one result, `Node.parents()` returns a list of matches.

```python
>>> node.parents()
[<ContractDefinition iterable 'Token'>, <SourceUnit iterable object 'contracts/Token.sol'>]
```

## Tests

To run the test suite:

```bash
$ tox
```
