CodeXGLUE -- Method Generation
Here is the introduction and pipeline for method generation task.
Task Definition
Method generation is the prediction of a method body implementation conditioned on a signature, a docstring, and any more context.
Dataset
We use CodeSearchNet Python dataset. The CodeSearchNet repositories are re-downloaded to extract all the methods, including their signatures, docstrings and bodies. We remove the methods that don't have docstrings and whose name contains 'test'. We preserve the context around this method for auxiliary information since it is really a difficult task to generator the method body only based on its signature/docstring. We also apply literal normalization for better user experience.
Data Format
The data format of each line in train/dev/test.jsonl is:
{
"signature": "def do_transform(self, v=<NUM_LIT:1>):",
"body": "if not self.transform:<EOL><INDENT>return<EOL><DEDENT>try:<EOL><INDENT>self.latest_value = utils.Transform ...",
"docstring": "Apply the transformation (if it exists) to the latest_value",
"id": "f19:c4:m1"
}
The id indicts where you can find this method in the raw data. In this instance, it means the 2nd method in the 2nd class in the 19th file. We apply literal normalization to function signature and body, replace \n with <EOL> and keep track in INDENT and DEDENT.
Data Statistics
Data statistics are shown in the below table.
