Properties
attribute
Gets the attribute being accessed in a chained attribute expression.
This property returns the Attribute component of a chained attribute expression (e.g., in object.attribute
, returns the attribute
part).
Args: None
Returns: Attribute: The attribute component of the chained expression.
extended
Returns a SymbolGroup of all extended nodes associated with this element.
Creates a SymbolGroup that provides a common interface for editing all extended nodes, such as decorators, modifiers, and comments associated with the element.
Args: None
Returns: SymbolGroup: A group containing this node and its extended nodes that allows batch modification through a common interface.
extended_source
Returns the source text representation of all extended nodes.
Gets the source text of all extended nodes combined. This property allows reading the source text of all extended nodes (e.g. decorators, export statements) associated with this node.
Returns: str: The combined source text of all extended nodes.
file
The file object that this Editable instance belongs to.
Retrieves or caches the file object associated with this Editable instance.
Returns: File: The File object containing this Editable instance.
filepath
The file path of the file that this Editable instance belongs to.
Returns a string representing the absolute file path of the File that contains this Editable instance.
Returns: str: The absolute file path.
full_name
Returns the full name of the attribute, including the object expression.
Gets the complete name representation of a chained attribute, which includes both the object and attribute parts (e.g., ‘my_object.my_attribute’).
Returns: str: The full string representation of the chained attribute expression.
function_calls
Returns a list of all function calls contained within this expression.
Traverses the extended nodes of this expression to find all function calls within it. This is useful for tasks like analyzing call patterns or renaming function invocations.
Returns: list[FunctionCall]: A list of FunctionCall objects representing all function calls contained within this expression.
object
Returns the object that contains the attribute being looked up.
Provides access to the object part of a chained attribute expression (e.g., in ‘A.method’, returns the ‘A’ part).
Returns: Object: The object component of the chained attribute expression. Guaranteed to be an instance of Chainable.
resolved_value
Returns the resolved value of an Expression.
Returns the last assigned expression value if the expression is resolvable, otherwise returns itself. For example, if ‘b = a’ where ‘a = 1’, resolving ‘b’ returns 1.
Returns: Union[Expression, list[Expression]]: The resolved expression value(s). Returns a single Expression if there is only one resolved value, or a list of Expressions if there are multiple resolved values. Returns self if the expression is not resolvable or has no resolved types.
source
Text representation of the Editable instance.
Returns the source text of the Editable instance. This is the main property used to access the text content of any code element in GraphSitter.
Returns: str: The text content of this Editable instance.
variable_usages
Returns Editables for all TreeSitter node instances of variable usages within this node’s scope.
This method finds all variable identifier nodes in the TreeSitter AST, excluding:
- Function names in function calls
- Import names in import statements
- Property access identifiers (except the base object)
- Keyword argument names (in Python and TypeScript)
This is useful for variable renaming and usage analysis within a scope.
Returns: list[Editable]: A list of Editable nodes representing variable usages. Each Editable corresponds to a TreeSitter node instance where the variable is referenced.
Methods
commit
Commits any pending transactions for the current node to the codebase.
Commits only the transactions that affect the file this node belongs to. This is useful when you want to commit changes made to a specific node without committing all pending transactions in the codebase.
Args: None
Returns: None
edit
Replace the source of this Editable
with new_src
.
Replaces the text representation of this Editable instance with new text content. The method handles indentation adjustments and transaction management.
Args:
new_src (str): The new source text to replace the current text with.
fix_indentation (bool): If True, adjusts the indentation of new_src
to match the current text’s indentation level. Defaults to False.
priority (int): The priority of the edit transaction. Higher priority edits are applied first. Defaults to 0.
dedupe (bool): If True, deduplicates identical transactions. Defaults to True.
Returns: None
find
Find and return matching nodes or substrings within an Editable instance.
This method searches through the extended_nodes of the Editable instance and returns all nodes or substrings that match the given search criteria.
Args: strings_to_match (Union[list[str], str]): One or more strings to search for. exact (bool): If True, only return nodes whose source exactly matches one of the strings_to_match. If False, return nodes that contain any of the strings_to_match as substrings. Defaults to False.
Returns: list[Editable]: A list of Editable instances that match the search criteria.
find_string_literals
Returns a list of string literals within this node’s source that match any of the given strings.
Args: strings_to_match (list[str]): A list of strings to search for in string literals. fuzzy_match (bool): If True, matches substrings within string literals. If False, only matches exact strings. Defaults to False.
Returns: list[Editable]: A list of Editable objects representing the matching string literals.
flag
Adds a visual flag comment to the end of this Editable’s source text.
Flags this Editable by appending a comment with emoji flags at the end of its source text. This is useful for visually highlighting specific nodes in the source code during development and debugging.
Returns: None
get_variable_usages
Returns Editables for all TreeSitter nodes corresponding to instances of variable usage that matches the given variable name.
Retrieves a list of variable usages that match a specified name, with an option for fuzzy matching. By default, excludes property identifiers and argument keywords.
Args: var_name (str): The variable name to search for. fuzzy_match (bool): If True, matches variables where var_name is a substring. If False, requires exact match. Defaults to False.
Returns: list[Editable]: List of Editable objects representing variable usage nodes matching the given name.
insert_after
Inserts code after this node.
Args: new_src (str): The source code to insert after this node. fix_indentation (bool, optional): Whether to adjust the indentation of new_src to match the current node. Defaults to False. newline (bool, optional): Whether to add a newline before the new_src. Defaults to True. priority (int, optional): Priority of the insertion transaction. Defaults to 0. dedupe (bool, optional): Whether to deduplicate identical transactions. Defaults to True.
Returns: None
insert_before
Inserts text before this node’s source with optional indentation and newline handling.
This method inserts the provided text before the current node’s source code. It can automatically handle indentation and newline placement.
Args: new_src (str): The text to insert before this node. fix_indentation (bool): Whether to fix the indentation of new_src to match the current node. Defaults to False. newline (bool): Whether to add a newline after new_src. Defaults to True. priority (int): Transaction priority for managing multiple edits. Defaults to 0. dedupe (bool): Whether to deduplicate identical transactions. Defaults to True.
Returns: None
reduce_condition
Reduces an editable to the following condition
remove
Deletes this Node and its related extended nodes (e.g. decorators, comments).
Removes the current node and its extended nodes (e.g. decorators, comments) from the codebase. After removing the node, it handles cleanup of any surrounding formatting based on the context.
Args: delete_formatting (bool): Whether to delete surrounding whitespace and formatting. Defaults to True. priority (int): Priority of the removal transaction. Higher priority transactions are executed first. Defaults to 0. dedupe (bool): Whether to deduplicate removal transactions at the same location. Defaults to True.
Returns: None
replace
Search and replace occurrences of text within this node’s source and its extended nodes.
This method performs string replacement similar to Python’s string.replace(), with support for regex patterns. It operates on both the main node and any extended nodes (e.g. decorators, exports).
Args: old (str): The text or pattern to search for. new (str): The text to replace matches with. count (int, optional): Maximum number of replacements to make. Defaults to -1 (replace all). is_regex (bool, optional): Whether to treat ‘old’ as a regex pattern. Defaults to False. priority (int, optional): Priority of the replacement operation. Defaults to 0.
Returns: int: The total number of replacements made.
Raises: ValueError: If there are multiple occurrences of the substring in a node’s source.
search
Returns a list of all regex match of regex_pattern
, similar to python’s re.search().
Searches for matches of a regular expression pattern within the text of this node and its extended nodes.
