ConvertConstantCommand

A command that acts identically to a visitor-based transform, but also has
class commands.constant_folding.ConvertConstantCommand(context: libcst.codemod.CodemodContext, string: str, constant: str)

Bases: libcst.codemod.VisitorBasedCodemodCommand

A command that acts identically to a visitor-based transform, but also has the support of add_args() and running supported helper transforms after execution. See CodemodCommand and ContextAwareTransformer for additional documentation.

Parameters

  • context (libcst.codemod.CodemodContext) –

  • string (str) –

  • constant (str) –

DESCRIPTION :str = Converts raw strings to constant accesses.
static add_args(arg_parser: argparse.ArgumentParser) → None

Override this to add arguments to the CLI argument parser. These args will show up when the user invokes libcst.tool codemod with --help. They will also be presented to your class’s __init__ method. So, if you define a command with an argument ‘foo’, you should also have a corresponding ‘foo’ positional or keyword argument in your class’s __init__ method.

Parameters

arg_parser (argparse.ArgumentParser) –

Return type

None

leave_SimpleString(self, original_node: libcst.SimpleString, updated_node: libcst.SimpleString) → Union[libcst.SimpleString, libcst.Name]
Parameters

  • original_node (libcst.SimpleString) –

  • updated_node (libcst.SimpleString) –

Return type

Union[libcst.SimpleString, libcst.Name]
