Inherits from
Expression, Editable, SymbolGroup
Properties
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.
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.
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
Get the source code content of the node.
Retrieves the underlying source code content associated with this node as stored in the _source attribute.
Returns: str: The source code content of the node.
symbols
Returns the list of symbols in the group.
Gets the list of symbols associated with this SymbolGroup. These symbols can be code elements like functions, classes, or variables that form a logical grouping.
Returns: list[Child]: A list of symbol objects that belong to this group.
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
Edit the source for this Collection instance.
This method is used to update the source of a Collection while preserving its start and end brackets. It is primarily used internally by Collection to maintain structural integrity during edits.
Args: *args: Variable length argument list passed to the parent Editable class’s edit method. **kwargs: Arbitrary keyword arguments passed to the parent Editable class’s edit method.
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.
index
Return the index of the first occurrence of value.
Returns -1 if value is not present.
insert
Adds value
to the container that this node represents
Args:
value: source to add
index: If provided, the value
will be inserted at that index, otherwise will default to end of the list.
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
Removes an element from a Collection.
Deletes the specified element from the Collection by calling its remove method. If no value is specified, delegates to the parent class’s remove method.
Args: value (Child | None): The element to remove from the Collection. If None, delegates to parent class. *args: Variable length argument list to pass to the remove method. **kwargs: Arbitrary keyword arguments to pass to the remove method.
Returns: None: This method doesn’t return anything.
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.
Args: regex_pattern (str): The regular expression pattern to search for. include_strings (bool): When False, excludes the contents of string literals from the search. Defaults to True. include_comments (bool): When False, excludes the contents of comments from the search. Defaults to True.
Returns: list[Editable]: A list of Editable objects corresponding to the matches found.
