Giving agents a more expressive way to act

Act via Code

Represents an argument passed into a FunctionCall.

Argument

Represents an assignment for a single variable within an assignment statement.
Attributes: left: The left side of the assignment right: The right side of the assignment
Example: ```typescript var z var z = 5 ```

Assignment

A class that represents an assignment statement in a codebase, such as `x = 1`, `a, b = 1, 2`, `const {a: b} = myFunc(),`, etc.
This includes potentially multiple Assignments via `statement.assignments`, which represent each assignment of a value to a variable within this statement.
For example, assigning to a destructured object, or assigning multiple values to multiple variables in a single statement.

AssignmentStatement

Abstract representation of an attribute on a class definition.

Attribute

An awaited expression, only found in asynchronous contexts, e.g. await(foo(bar))

AwaitExpression

Represents binary expressions, e.g. all of +,-,*,/, as well as booleaneoperations (and, or) etc.

BinaryExpression

BlockStatement

Boolean

Any symbol that can be invoked with arguments eg.
Function, Class, Decorator, ExternalModule

Callable

Abstract representation catch clause.
Attributes: code_block: The code block that may trigger an exception condition: The condition which triggers this clause

CatchStatement

An attribute of an object. (IE a method on a class, a function from a module, etc)
Examples: A.method()

ChainedAttribute

Abstract representation of a Class definition.

Class

Container class for a list of code Statements that share an indentation level, e.g. a function body or class body.
Enables various types of queries and operations on the code block.

CodeBlock

This class provides the main entrypoint for most programs to analyzing and manipulating codebases.
It provides a high-level interface to interact with the codebase graph, and provides methods to access and manipulate files, directories, symbols, and other entities in the codebase.

Codebase

Abstract representation of comment statements.

Comment

A group of comments that form a larger comment block.

CommentGroup

Any comparison expression in the code.
Includes all set of `<`, `<=`, `>`, `>=`, `==`, `!=` etc.

ComparisonExpression

Decorator

Represents a dict (object) literal the source code.
You can use standard Python operations to operate on this dict (i.e. `len`, `del`, `set`, `get`, etc)

Dict

Directory representation for codebase. GraphSitter abstraction of a file directory that can be used to look for files and symbols within a specific directory.

Editable

Represents a single symbol being exported.

Export

Abstract representation of a single export statement that appears in a file. One export statement can export multiple symbols from a single source.
Attributes: exports: A list of the individual exports this statement represents

ExportStatement

An interface for any node object that can be exported eg. Class, class name,  top-level functions, imports

Exportable

Represents an arbitrary Expression, such as List, Dict, Binary Expression, String.

Expression

ExpressionGroup

Abstract representation of any expression statements that resolves to an expression. In some languages without a statement delimiter, expression statement and the enclosed expression looks the same in text.
For example, in Python: ```python x = 1 ``` The above code is an expression statement, but its expression value is an assignment.
In Typescript: ```typescript x = 1; ``` The above code is also an expression statement, but its expression value is an assignment excluding the semicolon.

ExpressionStatement

Represents an external module, like `datetime`, that can be referenced.
These are only added to the graph during import resolution and will not exist in a local file's subgraph. This is because we don't know what an import is referencing or resolves to until we see the full codebase.

ExternalModule

Represents a generic file.
Could represent a source file or a non-code file such as a markdown file or image file.

File

Kwargs for the flag_instance method of the Codebase class.
Attributes: message: The message to be displayed in the diff preview or posted as a comment on the PR. message_type: Where the message will be sent (CODEGEN, GITHUB, SLACK) message_recipient: The recipient of the message.

FlagKwargs

Abstract representation of the for loop.
Attributes: code_block: The code block that is executed in each iteration of the loop
