A system for Python that generates static type annotations by collecting runtime types

Overview

MonkeyType

MonkeyType collects runtime types of function arguments and return values, and can automatically generate stub files or even add draft type annotations directly to your Python code based on the types collected at runtime.

Example

Say some/module.py originally contains:

def add(a, b):
    return a + b

And myscript.py contains:

from some.module import add

add(1, 2)

Now we want to infer the type annotation of add in some/module.py by running myscript.py with MonkeyType. One way is to run:

$ monkeytype run myscript.py

By default, this will dump call traces into a SQLite database in the file monkeytype.sqlite3 in the current working directory. You can then use the monkeytype command to generate a stub file for a module, or apply the type annotations directly to your code.

Running monkeytype stub some.module will output a stub:

def add(a: int, b: int) -> int: ...

Running monkeytype apply some.module will modify some/module.py to:

def add(a: int, b: int) -> int:
    return a + b

This example demonstrates both the value and the limitations of MonkeyType. With MonkeyType, it's very easy to add annotations that reflect the concrete types you use at runtime, but those annotations may not always match the full intended capability of the functions. For instance, add is capable of handling many more types than just integers. Similarly, MonkeyType may generate a concrete List annotation where an abstract Sequence or Iterable would be more appropriate. MonkeyType's annotations are an informative first draft, to be checked and corrected by a developer.

Motivation

Readability and static analysis are the primary motivations for adding type annotations to code. It's already common in many Python style guides to document the argument and return types for a function in its docstring; annotations are a standardized way to provide this documentation, which also permits static analysis by a typechecker such as mypy.

For more on the motivation and design of Python type annotations, see PEP 483 and PEP 484.

Requirements

MonkeyType requires Python 3.6+ and the libcst library (for applying type stubs to code files). It generates only Python 3 type annotations (no type comments).

Installing

Install MonkeyType with pip:

pip install MonkeyType

How MonkeyType works

MonkeyType uses the sys.setprofile hook provided by Python to interpose on function calls, function returns, and generator yields, and record the types of arguments / return values / yield values.

It generates stub files based on that data, and can use libcst to apply those stub files directly to your code.

See the full documentation for details.

`monkeytype run manage.py test` doesn't produce sqllite file

I've run monkeytype run manage.py test in my django project after pip install monkeytype (inside of a virtual env) and I'm not seeing any output of the sqllite file described in the README.

Running monkeytype stub for any of my modules doesn't work either. If there's something different that I have to do for django tests, let's add that to the README. Otherwise, am I missing something?

record per-key types for heterogenous dicts and suggest TypedDict annotation

Currently MonkeyType assumes dicts are homogenous. When heterogenous dicts are seen, we just combine all the value types into a Union (and then if that Union gets too big, by default we rewrite it to Any). It'd be more useful in such cases to suggest a TypedDict annotation with per-key value types.

The trick here is that we don't really know the intention, so there'd be some level of heuristic involved. Like, if there's multiple non-None value types (and probably if the number of keys is less than some threshold), rather than recording just a single value type, we record per-key value types. Then we'd also need some smarts when combining traces into an annotation: if we have any traces with per-key value types, try to construct a consistent TypedDict, but if we find that key names and value types aren't matching up consistently, fallback to normal Dict.

There's enough fuzziness in the heuristics here and this'd be enough work that it might not be worth it, but for codebases that use lots of heterogenous dicts, it'd make the generated annotations a lot more useful.

MonkeyType is not working in IPython

The newer version of MonkeyType does not work in IPython. I think https://github.com/Instagram/MonkeyType/commit/e8bb8a687e18dbb3c734ef33501a573265465c9d could be the reason.

An interactive session in IPython will assert __name__ == '__main__' it would still be meaningful to capture the CallTrace so folks could interactively type their notebook/python source.

I can totally understand if this falls outside the scope of the project.

monkeytype / retype doesn't apply stubs in __init__.py

For one of my modules, I ran test cases via monketype run, I can see the traces in the sqlite3 database, and I can run 'monketype stub modulename' and see what looks like valid stub output.

However, when I run 'monkeytype apply modulename', it returns no errors but the module is not modified.

I've been able to successfully update other modules. This module is my only good repro so far. There are no errors anywhere. I'm open to ideas on how to proceed. I guess i can start with debugging monkeytype?

Support PEP 604 Union syntax (Union[a, b] → a | b)
PEP 604 introduces a new Union syntax in Python 3.10+. It would be nice if Monkeytype could leverage that, and perhaps have a flag to use a union with None rather than the Optional type.

And are there any other async or builtin types that need this special handling?

Even though traces that don't decode usually get ignored, async types are probably very meaningful for the codebase.

"Failed collecting trace" and then lots of exceptions

Should be a pretty easy repro.

Create a Dockerfile with the following contents:

FROM ubuntu:20.04
RUN apt-get update
RUN apt-get install -y python3 python3-pip
RUN pip3 install monkeytype
RUN echo "from pkg_resources.extern import six" > repro.py

Then build it with docker build --network=host -t repro . and start with docker run --rm -it repro bash (or whatever).

Can verify that the import works correctly:

root@2ed6e4080312:/# python3 repro.py
root@2ed6e4080312:/#

(python3 here is 3.8)

But this doesn't work through MonkeyType:

We don't need to print the full traceback, and we could probably hint people that even if a few traces failed to collect that doesn't mean useful type traces weren't still collected.
