Methods

add_comment

Adds a new comment to the symbol.

add_decorator

Adds a decorator to a function or method.

add_keyword

Insert a keyword in the appropriate place before this symbol if it doesn’t already exist.

add_statements

arrow_to_named

Converts an arrow function to a named function in TypeScript/JavaScript.

asyncify

Modifies the function to be asynchronous, if it is not already.

convert_props_to_interface

Converts React component props to TypeScript interfaces.

dependencies

Returns a list of symbols that this symbol depends on.

edit

Replace the source of this node with new_src.

find

Find and return matching nodes or substrings within an Editable instance.

find_string_literals

Returns a list of string literals within this node’s source that match any of the given

flag

Flags a TypeScript symbol by adding a flag comment and returning a CodeFlag.

get_component

Returns a specific JSX element from within this symbol’s JSX elements.

get_import_string

Generates the appropriate import string for a symbol.

get_name

Returns the name node of the object.

get_parameter

Gets a specific parameter from the callable’s parameters list by name.

get_parameter_by_index

Returns the parameter at the given index.

get_parameter_by_type

Retrieves a parameter from the callable by its type.

get_variable_usages

Returns Editables for all TreeSitter nodes corresponding to instances of variable usage

insert_after

Inserts code after this node.

insert_before

Inserts text before the current symbol node in the Abstract Syntax Tree.

insert_statements

Inserts lines of code into the function body at the specified index.

is_child_of

Checks if this node is a descendant of the given editable instance in the AST.

is_valid_node

Determines if a given tree-sitter node corresponds to a valid function type.

is_wrapped_in

Check if this node is contained another node of the given class

move_to_file

rename

Renames a symbol and updates all its references in the codebase.

rename_local_variable

Renames a local variable and all its usages within a function body.

replace
